BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a Zero Insertion Force (hereinafter referred to as "ZIF") connector for inserting a contact into a mating contact with no insertion force.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional ZIF connector includes an insulator 53 and an insulator 53.
(Pin connector) 5 having a plurality of conductive contacts (pin contacts) 51 arranged on one surface 50 of the other, and a mating insulator 63, and a mating surface 60 of the mating insulator 63 facing the one surface 50. And a mating connector (socket connector) 6 having a mating contact (socket contact) 61 disposed in the connector. In this ZIF connector, one surface 50 and the mating surface 6
The connector 5 and the mating connector 6 are relatively moved in a second direction B (see FIG. 6) orthogonal to a first direction A in which the contact 51 approaches each other, so that the distal end of the contact 51 is moved. The connection is made by pressing the mating contact 61 while being elastically deformed.

More specifically, on one surface 50 of an insulator 53, a relatively thin and long conductive pin contact 51 is provided upright. A plurality of conductive socket contacts 61 are erected on a mating surface 60 of the mating insulator 63. A socket hole 62 is formed in the socket contact 61 for receiving the tip of the pin contact 51 in the socket portion 64. The hole diameter of the socket hole 62 is set to be larger than the diameter of the pin contact 51.

[0004] In this type of ZIF connector, after the pin contact 51 is inserted into the socket contact 61 in the first direction A, as shown in FIG. Direction B
, The pin contact 51 and the socket contact 61 are connected. in this case,
The second direction B may be the opposite direction as shown. While the pin contact 51 is elastically deformed by the movement of the mating insulator 63 , the tip end of the pin contact 51 presses and contacts two locations on the inner wall of the socket hole 62 to maintain an electrical connection between them. It is.

[0005] The forces received by the socket contacts 61 from the pin contacts 51 are shown as "P" and "F".

In the above-described ZIF connector, the forces received per one of the plurality of socket contacts 61 are P and F, which are opposite to each other, and the force supporting the socket contacts 61 against them is “PF”. "is required.

Therefore, the force for holding the whole in the state shown in FIG. 6 can be obtained by assuming that the number of pin contacts 51 is "n".
It becomes "nx (P-F)".

Since the force for simply bringing the n pin contacts 51 into contact with the socket contacts 61 is "nxP", such a structure of the ZIF connector can be driven with a smaller force. Useful in terms.

[0009]

However, in the above-described structure, each pin contact 51 must be inclined as shown in FIG. In addition, "PF"
In order to reduce the size, it is necessary to make the pin contact 51 thinner to have a longer dimension.

As described above, when the pin contact 51 is made thin and long, as shown in FIG. 7, when the pin contact 51 is machined, assembled into the insulator 53, or handled. Since each of the pins 51 is deformed irregularly, the tip positions of the pin contacts 51 are also irregularly arranged.

For this reason, even if an attempt is made to connect the pin connector 5 and the socket connector 6, the pin contact 51 does not fit into the socket contact 61, and the pin connector 5 and the socket connector 6 cannot be connected.

Further, in order to correct the irregularity of the pin contacts 51 of the ZIF connector shown in FIG. 7, as shown in FIG. 8, an insulator 53 and a mating insulator 63 are provided.
It is conceivable that the locator 9 is disposed between the locator 9 and the pin contact 51 to be inserted into the insertion hole 10 of the locator 9 and aligned. However, in this case, as shown in FIG. 6, when the pin connector 51 and the mating connector 6 are relatively moved to elastically deform the pin contact 51, when the pin contact 51 touches the inner wall of the insertion hole 10, the pin Contact 5
Since the contact pressures P and F between the first contact 1 and the mating contact 61 fluctuate and the contact becomes unstable, the pin contact 51 is inserted into the insertion hole 1.
It is necessary to enlarge the insertion hole 10 to some extent so as not to touch the inner wall of the zero. Even if the pin contacts 51 are inserted through the insertion holes 10 of the locator 9, if the pin contacts 51 are not aligned properly, they cannot be aligned.

Therefore, the problem of the present invention has been proposed in view of such problems of the prior art, and even if the tip positions of the pin contacts are not uniform at the time of manufacturing a ZIF connector or the like. A ZIF connector capable of aligning the tip positions of each pin contact, and obtaining a normal contact state without disturbing the behavior of the pin contact at the time of connection with the socket contact, and enabling a reliable connection. Is to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. In this embodiment, the same parts as those in FIG.

Referring to FIG. 1, a ZIF connector includes an insulator 53 and one surface 50 of the insulator 53.
Multiple conductive contacts (pin contacts) placed on top
And a mating contact (socket contact) 61 disposed on a mating surface 60 of the mating insulator 63 opposing the one surface 50. Included connector (socket connector) 6. In this ZIF connector, the socket connector 6 is moved in the second direction (shown in FIGS. 1 and 3) B and C orthogonal to the first direction A in which the one surface 50 and the mating surface 60 approach each other. The contact 51 is pressed against the socket contact 61 while elastically deforming the distal end of the contact 51 for connection.

More specifically, on one surface 50 of the insulator 53, a plurality of relatively thin and long conductive pin contacts 51 are erected. A plurality of conductive socket contacts 61 are erected on a mating surface 60 of the mating insulator 63. Socket contact 6
A socket hole 62 is formed in the socket portion 64 for receiving the tip of the pin contact 51 in the socket portion 64. The hole diameter of the socket hole 62 is set to be larger than the diameter of the pin contact 51.

The locator 1 is provided between one surface 50 of the insulator 53 and a mating surface 60 of the mating insulator 63. Locator 1 includes a pair of uprights 11, 1 erected in the first direction A on the upper surface of insulator 53.
2 and a contact insertion portion 13 provided so as to bridge between the standing legs 11 and 12 at a substantially middle position in the vertical direction between the standing legs 11 and 12. The contact insertion portion 13 includes a plurality of conductive pin contacts 5.
A plurality of insertion holes 15 for inserting one through one are formed. The locator 1 and the socket connector 6 have engagement means for engaging them. The engagement means is provided so as to protrude from one surface of the mating insulator 63.
The locator 1 has a projection 70 and a recess 18 provided between the uprights 11 and 12 of the locator 1. That is, the mating insulator 63 and the locator 1 are engaged with each other in an uneven relationship by the protrusion 70 and the recess 18 .

As shown in FIG. 1, the connection method in this type of ZIF connector is as follows. First, the locator 1 is moved in the second direction so that the bottom surfaces of the standing portions 11, 12 slide on one surface 50 of the insulator 53. C direction of B and C (Fig. 1
To the right of the paper). In this case, Pinkontaku
G is in a state in which the locator 1 that moves in the C direction abuts against the inner wall surface of the insertion hole 15 and is pressed, and furthermore, the tip ends of the pin contacts 51 are aligned.
The posture is maintained at a position where the tip of the contact 15 is loosely fitted in the socket hole 62. By doing so, even if the postures of the pin contacts 51 are not uniform, they are corrected by this,
The tips of the pin contacts 51 are aligned.

The insertion hole 15 may have a circular shape as shown in FIG. 2A, or may have a moving direction (second directions B and C) as shown in FIG. 2B. Long oval shape. That is, the insertion hole 15 is set to a size larger than the diameter of the pin contact in order to allow deformation of the pin contact 51 at the time of pressing contact between the pin contact 51 and the socket portion 61 described later ,
The pin contact 51 comes into contact with the inner wall surface of the insertion hole 15 and is pushed.
From the attached state, engage with the mating insulator 63

As a result, the pin contact 51 separates from the inner wall surface,
The diameter of the pin contact so that it does not touch the surface
The size is larger than the size.

Next, with the pin contacts 51 aligned, the pin connector 5 and the socket connector 6 are relatively approached, and the tip of each pin contact 51 is inserted into the corresponding socket hole 62. Insertion into the socket hole 62 can be performed smoothly because the pin contacts 51 are aligned.

In this state, the mating insulator 6
3 is coupled to locator 1. The connection between the two is formed so that the mating surface of the socket contact 61 protrudes toward one surface of the insulator 53, while the distance dimension L 1 between the upright portions 11 and 12 of the locator 1 is set to the mating insulator 63. This can be achieved by setting the protruding portion (the portion having the width L2) 70 to be fittable. That is, the dimension L1 between the standing portions 11 and 12 of the locator 1 is set to be equal to or slightly larger than L2. In this way, the pin
The contact 51 is connected to the socket contact 61 by a zero insertion force.

Next, as shown in FIG. 3, with the pin contacts 51 aligned, the socket connector 6 is moved with respect to the pin connector 5 in the direction B opposite to the direction C. Due to the movement of the mating insulator 63 and the locator 1, the pin contact 51 is elastically deformed while the tip of the pin contact 51 is positioned above the inner wall of the socket hole 62.
By pressing and contacting the lower two places, the two are maintained in an electrically connected state.

As described with reference to FIG. 6, the force for bringing the n pin contacts 51 into contact with the socket contact 61 is "nxP".
In the structure of the connector, it can be driven with a smaller force. Also, the coupling means between the other insulator 63 and the locator 1 is not limited to this,
Needless to say, it may be performed by other known means.

FIG. 4 shows another embodiment of the ZIF connector of the present invention. In the embodiment shown in FIGS. 1 to 3, the locator 1 for aligning the pin contact 51 the second direction B, and are to be moved manually in the C direction of C, the movement It is configured to be performed without manual operation. The same parts as those in the embodiment shown in FIGS. 1 to 3 are denoted by the same reference numerals, and description thereof will be omitted. In the ZIF connector shown in FIG. 4, the stopper 5 for regulating the range of movement of the locator 1 in the C direction among the second directions B and C of the locator 1 and the direction C with respect to the stopper 57 are different. A holding portion 55 provided in the opposite direction B is provided. Holder 55 and Holder 55
An elastic member 3 for urging the locator 1 in a predetermined direction C is provided between the locator 1 and the outer surface of the locator 1 facing the locator 1. As described above, the locator 1 is moved in the second direction B or C in the second direction B or C.
A holding portion 55 that serves as a spring seat for holding and holding the spring 3 in the insulator 53, and a stopper that prevents the locator 1 from moving further, provided with an elastic member (spring) 3 that elastically biases the locator 1 in the direction. What is necessary is just to form the part 57. Then, the socket connector 6 is connected in the second direction B, C
When the locator 1 is moved in the direction C, a gap is formed between the locator 1 and the stopper 57.

Therefore, if a block having the size of the gap is sandwiched between the gaps, the pin contact 51 can be kept in a state of being pressed against the socket hole 62 of the socket contact 61.
