<Embodiment>
An electric wire with a terminal 1 according to an embodiment of the present invention, which includes an electric wire 10 and an insulation displacement terminal 20 according to an embodiment of the present invention, will be described below with reference to the drawings. Furthermore, a connector 3 according to an embodiment of the invention, which includes an insulation displacement terminal 20 according to an embodiment of the invention and a housing 2, will also be described. In particular, as shown in FIGS. 1, 2, and 6, a plurality (two) of press-connecting terminals 20 are attached to the housing 2 in a state of being integrally formed and electrically connected through the connecting portion 31. As shown in FIG. Furthermore, each of the plurality of insulation displacement terminals 20 is attached to the corresponding electric wire 10 . As a result, the two electric wires 10 are electrically connected via a plurality (two) of pressure contact terminals 20, and the connection points between the wires 10 and the pressure contact terminals 20 are protected by the housing 2. FIG.

Hereinafter, for convenience of explanation, as shown in FIGS. 1 and 2, "front-rear direction", "vertical direction", "width direction", "front", and "rear" are defined. The front-back direction, the up-down direction, and the width direction are orthogonal to each other. The front-rear direction coincides with the extending direction of the electric wire 10 . Each component constituting the electric wire with terminal 1 will be described in order below.

First, the electric wire 10 will be described. As shown in FIG. 2 , the electric wire 10 has a long metal conductor core wire 11 and a resin coating 12 that covers the side surface of the conductor core wire 11 . In this example, the cross section of the electric wire 10 has a circular shape, but it may have a shape other than a circular shape such as a rectangular shape.

Next, the pressure contact terminal 20 will be described. As shown in FIG. 2(a), the pressure contact terminal 20 is formed by pressing and bending a single flat metal plate. The pressure contact terminal 20 includes a pair of bottom plate portions 21 arranged in the front-rear direction, and a pair of upright plate portions 22 standing upward from the ends of the pair of bottom plate portions 21 on the front-rear direction inner side (sides facing each other). , an upper plate portion 23 that connects the upper end portions (extending ends) of the pair of standing plate portions 22 in the front-rear direction, and the ends of the pair of bottom plate portions 21 on the front-rear direction outer side (opposite side to the side facing each other). and a pair of barrel portions 24 provided in the . The pair of standing plate portions 22 (that is, pressure contact blades 25 to be described later) and the upper plate portion 23 are formed in an arch shape as a whole.

The pair of bottom plate portions 21 are a pair of flat plates whose thickness direction is oriented in the vertical direction, and are spaced apart in the front-rear direction so as to form one plane.

The pair of erected plate portions 22 are a pair of flat plates whose thickness direction is oriented in the front-rear direction, and are opposed to each other with a gap therebetween in the front-rear direction. Each standing plate portion 22 is provided with a pressure blade 25 configured to define a pressure slot 26 in the widthwise central portion thereof. More specifically, the press contact blades 25 are configured to have shapes facing each other in the width direction with the press contact slots 26 interposed therebetween. As a result, the two press contact blades 25 are arranged side by side with a space therebetween in the front-rear direction. The press contact slot 26 is a groove-shaped space that opens upward and extends downward. Therefore, the upper plate portion 23 specifically connects the upper end portions of the pressure contact blades 25 on one side in the width direction and the upper end portions of the pressure contact blades 25 on the other side in the width direction to each other in the front-rear direction. .

As shown in FIG. 3A, the press-contact blade 25 has an opening 27 located on the upper side and a conducting portion 28 that continues to the lower side of the opening 27 . The opening 27 is a portion where the interval between the pressure contact slots 26 becomes narrower as it goes downward (closer to the bottom plate portion 21 ), and functions to break through the coating 12 of the wire 10 and guide the wire 10 to the conductive portion 28 . .

The conductive portion 28 is a portion in which the distance between the pressure contact slots 26 is kept constant in the vertical direction, and functions to conduct the conductor core wire 11 of the electric wire 10 press-fitted into the pressure contact slot 26 . At the lower end of the conductive portion 28, the space between the pressure contact slots 26 becomes narrower as it goes downward, and the lower end of the conductive portion 28 is positioned upwardly away from the bottom plate portion 21 by the dimension L (FIG. 3A). reference).

The pair of barrel portions 24 are positioned so as to sandwich the pair of standing plate portions 22 (thus, the two press contact blades 25) in the front-rear direction. Each barrel portion 24 has a pair of crimping pieces 29 standing upward as shown in FIG. 2(a). The pair of crimping pieces 29 are a pair of flat plates whose thickness direction is oriented in the width direction, and are opposed to each other with a gap in the width direction. The pair of barrel portions 24 hold the wire 10 so as to keep the conductor core wire 11 positioned in the conductive portion 28 of the pressure contact slot 26 (see FIG. 2(b), etc.).

Further, in this example, as shown in FIG. 4, the position of the pressure contact blade 25 at which the wire 10 is pressed and the position at which the wire 10 is held by the pair of barrel portions 24 substantially match in the vertical direction. Therefore, the electric wire 10 positioned between the pair of barrel portions 24 extends substantially linearly over the entire area in the front-rear direction.

In this example, as shown in FIG. 2(a), two press-connecting terminals 20 are connected to each other in the width direction by connecting portions 31 that connect to the bottom plate portions 21 of each other, and are electrically connected. Thus, the two pressure contact terminals 20 electrically connected to each other are attached to the housing 2 . In the above, each part which comprises the electric wire 1 with a terminal was demonstrated.

Next, the housing 2 and the connector 3 will be explained. As shown in FIG. 1, the housing 2 made of resin includes a base portion 41, a lid portion 42 that closes an upper opening of the base portion 41, and a hinge portion 43 that connects the lid portion 42 to the base portion 41 so that it can be opened and closed. Prepare for unity. The housing 2 constitutes a rectangular box-shaped casing when the lid portion 42 is closed (see also FIG. 6(c)).

The base portion 41 includes a rectangular bottom portion 44 and a pair of side plate portions 45 extending in the front-rear direction and extending in the front-rear direction. One end side of the hinge portion 43 is connected to the front-back direction central portion of the upper end portion of one side plate portion 45 of the pair of side plate portions 45 . A locking projection 46 projecting outward in the width direction is formed at the center of the widthwise outer surface of the other side plate portion 45 of the pair of side plate portions 45 .

At a predetermined position on the upper surface (inner surface) of the bottom portion 44 of the base portion 41, as shown in FIG. is fixed to The fixing of the pressure contact terminal 20 is achieved by fixing at least one of the bottom plate portion 21 and the coupling portion 31 of the pressure contact terminal 20 to the upper surface of the bottom portion 44 of the base portion 41 by a known method. Thereby, the connector 3 is obtained.

In the open state shown in FIG. 1(a), the lid portion 42 includes a rectangular top plate portion 47 and side plate portions 48 that stand upward from the edges on one side in the width direction of the top plate portion 47 and extend in the front-rear direction. and a pair of front and rear plate portions 49 standing upward from both front and rear side edges of the top plate portion 47 and extending in the width direction, and are open in the other side in the upper direction and the width direction. The other end side of the hinge portion 43 is connected to the center portion in the front-rear direction of the edge portion extending in the front-rear direction on the other side in the width direction of the top plate portion 47 .

In each of the pair of front and rear plate portions 49, two insertion portions 51 for inserting two wires 10 arranged in the width direction are formed side by side in the width direction. Each insertion portion 51 is a groove portion recessed toward the top plate portion 47 . Instead of the side plate portion 48 , a locking piece 52 is formed independently of the side plate portion 48 and standing upright from the top plate portion 47 in a tongue-like shape. The locking hole of the locking piece 52 is adapted to be locked to the locking projection 46 of the base portion 41 when the lid portion 42 is closed. The housing 2 and the connector 3 have been described above.

Next, a method for attaching the pressure contact terminal 20 to the electric wire 10 will be described. In this embodiment, the pressure contact terminal 20 is attached to the electric wire 10 using the pressure contact jig 60 shown in FIG. The pressure contact jig 60 is made of resin or metal, and includes a base portion 61 extending in the front-rear direction, a pressure contact projection 62 projecting downward from the lower portion of the base portion 61 and extending in the front-rear direction, and the pressure contact projection 62 extending in the front-rear direction. A pair of crimping crimpers 63 protruding downward from the lower portion of the base portion 61 so as to be sandwiched between them are integrally provided.

In order to attach the pressure contact terminal 20 to the electric wire 10 using the pressure contact jig 60, first, as shown in FIG. Using a jig 60 , one of the two wires 10 is attached to one of the two pressure contact terminals 20 fixed to the base 41 of the housing 2 .

Specifically, the electric wire 10 is placed in the opening 27 (pressing slot 26) of the pressing blade 25, and in the space between the pair of crimping pieces 29 positioned on both sides of the opening 27 in the front-rear direction. The pressure welding jig 60 arranged above the electric wires 10 is pressed downward while the electric wires 10 are arranged so as to be inserted through them. As a result, the press-contact projections 62 push downward the wire 10 placed in the opening 27 , and each of the pair of crimping crimpers 63 presses the tip of the corresponding pair of crimping pieces 29 . do.

When the press-contact projection 62 pushes downward the wire 10 placed in the opening 27 of the press-contact blade 25, the coating 12 of the wire 10 is eaten away and the conductor core wire 11 is exposed. It enters between the conducting portions 28 (see FIGS. 2(b), 3(b), and 4). This achieves electrical connection between the conductor core wire 11 and the conductive portion 28 (that is, electrical connection between the pressure contact terminal 20 and the wire 10).

Each crimping crimper 63 presses the tips of the pair of crimping pieces 29 so that the pair of crimping pieces 29 positioned above the electric wire 10 inserted into the space between the pair of crimping pieces 29 is pushed. are crimped so as to engage with each other (see FIGS. 2(b), 3(b) and 4). In this example, the tips of the pair of crimping pieces 29 are engaged so that the tip of one crimping piece 29 overlaps the tip of the other crimping piece 29. . As a result, the electric wire 10 positioned in the space between the pair of crimping pieces 29 can be prevented from coming out upward from the space, so that the electric wire 10 press-fitted into the conducting portion 28 of the press contact blade 25 can be pushed upward. Pulling out (that is, moving toward the opening 27 of the press contact blade 25) can be suppressed.

Through the steps described above, first, one of the two wires 10 is attached to one of the two pressure contact terminals 20 fixed to the base portion 41 of the housing 2 (see FIG. 6). (a)). As a result, the electric wire 1 with a terminal is obtained for one pressure contact terminal 20 .

Then, the other electric wire 10 of the two electric wires 10 is also attached to the other insulation displacement terminal 20 by the same procedure, as shown in FIG. 6(b). As a result, the electric wire 1 with a terminal is obtained for the other insulation displacement terminal 20 . Further, the two electric wires 1 with terminals are electrically connected to each other via the connecting portion 31 (see FIG. 2) that connects the two pressure contact terminals 20 .

Then, as shown in FIG. 6C, the lid portion 42 of the housing 2 is closed so that the corresponding electric wires 10 extend from the insertion portions 51 of the lid portion 42 of the housing 2, respectively. The locking hole of the locking piece 52 is locked to the locking projection 46 of the base portion 41 . This completes the attachment of the housing 2 to the two electric wires 1 with terminals. By completing the attachment of the housing 2, as shown in FIG. protected by

Therefore, the pressure contact terminal 20 of this configuration can prevent the wire 10 from being detached or misaligned even when an unintended external force is applied to the press-fitted wire 10, compared to the conventional pressure contact terminal 20 described above. Therefore, the press contact terminal 20 can properly hold the electric wire 10 that has been press-fitted into the press contact slot 26 .

Furthermore, according to the press contact terminal 20, the wire 10 is held by the barrel portion 24 so that the contact between the conductor core of the wire 10 and the conductive portion 28 of the press contact slot 26 is maintained.

In the above embodiment, in the vertical direction, the pressure contact position with the wire 10 by the pressure contact blade 25 and the holding position of the wire 10 by the pair of barrel portions 24 substantially match (see FIG. 4). On the other hand, as shown in FIG. 7, the position where the pressure contact blade 25 contacts the wire 10 may be positioned above the position where the wire 10 is held by the pair of barrel portions 24 . According to this configuration, the barrel portion 24 exerts a force in the direction (downward) for press-fitting the electric wire 10 into the press-contact blade 25 , so that the state in which the wire 10 is firmly press-fitted into the press-contact blade 25 can be maintained. Therefore, in addition to unintended movement of the electric wire 10 in the erecting direction (vertical direction), unintended movement of the electric wire 10 in the axial direction of the electric wire 10 can also be restricted.
