Embodiment 2 FIG. 4 shows a second embodiment of the present invention, in which the area of the lower opening of the cover 7 is larger than the area of the upper surface of the base 6. The base 6 is formed into an elongated shape, and substantially L-shaped legs 13 are integrally extended from both ends of the base 6 in the longitudinal direction. Connecting protrusions 25 are protruded from both ends of the base 6 in the longitudinal direction, and each connecting protrusion 25 has an engagement hole 14 formed therein. Similar to the first embodiment, a hook 17 at the tip of an engaging piece 16 extending from the lower edge of the cover 7 engages with the periphery of the engaging hole 14, thereby connecting the base 6 and the cover 7. I'm trying to make it happen. Attachment holes 15 are opened in the legs and extend vertically through the legs, and by inserting a fixing device such as a screw through the attachment holes 15, the base 6 can be fixed to a wall or the like. In addition, the mounting hole 15 is a long hole elongated in the width direction of the base 6 as in the first embodiment, so that the position of the base 6 can be adjusted while the base 6 is fixed to a wall or the like. It's getting old.
The connector 5 is disposed on the base 6 with the insertion port 3 open upward, and is disposed substantially in a straight line along the longitudinal direction of the base 6. The connector 5 is fixed to the base 6 by sandwiching the connector 5 between each pair of holding pieces 12 protruding from the base 6 in correspondence with each connector 5, as in the first embodiment. The hook portion 23 formed at the upper end of the holding piece 12 may be engaged with the upper surface of the connector 5.
Since the upper surface of the base 6 has a smaller area than the opening on the lower surface of the cover 7 as described above, there is no space between the cover 7 and the base 6 when the cover 7 is engaged with the base 6. A gap is formed, and the electric wire 4 can be introduced into the cover 7 through this gap. The electric wires 4 introduced into the cover 7 in this manner are connected to the connector 5 to be electrically connected to each other as in the first embodiment.

Embodiment 3 The one shown in FIG. 5 is a third embodiment, in which the base 6 is formed into an elongated shape as in the second embodiment,
Approximately L-shaped legs 13 are integrally extended from both ends in the longitudinal direction. In the above two examples, the connector 5 was arranged on the top surface of the base 6 with the insertion port 3 opened upward, but in this embodiment, the insertion port 3 was opened on the side surface of the base 6. A connector 5 is disposed in the shape of the connector. The connector 5 is attached to the base 6 in the same way as in the above two examples, and the connector 5 is held between the holding pieces 12 provided on the side of the base 6, one pair for each connector 5. A hook portion 2 formed at the tip of the piece 12
The connector 5 is fixed to the base 6 by locking the connector 3 to one surface of the connector 5. The engagement hole 14 is formed in the center of the leg in the vertical direction, and an engagement piece 16 extending from the lower edge of the cover 7 is inserted into the engagement hole 14. The cover 7 is coupled to the base 6 by engaging the hook 17 with the circumferential edge of the engagement hole 16. Also,
The electric wire 4 is connected to the cover 7 and the base 6 as in the second embodiment.
are introduced into the cover 7 through the gap between them, and are electrically connected to each other by being connected to the connector 5.

Embodiment 4 The one shown in FIGS. 6 and 7 is a fourth embodiment, which has substantially the same structure as the first embodiment, but the lower surface of the base 6 has sawtooth-shaped A holding portion 30 is formed. The holding part 30 is the base 6
When the base 6 is fixed to the wall surface 31, it is formed so as to leave a space slightly smaller than the diameter of the electric wire 4 between it and the wall surface 31, and by fixing the base 6 to the wall surface, the electric wire 4 can be held down. The electric wire 4 is held between the wall surface and the base 6 with the lower end portion of the portion 30 biting in to prevent the electric wire 4 from shifting.
With this configuration, the electric wire 4 is fixed at the same time as the base 6 is fixed to the wall surface, and the electric wire 4 is prevented from coming off from the connector 5 even if tension is applied from the outside to the electric wire 4 connected to the connector 5. It is something that can be done.

8 and 9 show the mounting structure of the connector 5 on the base 6 in each of the above embodiments. A holding hole 35 is formed at the position where the is attached. The holding hole 35 has a substantially rectangular shape, and a pair of opposing sides are recessed to form a removal hole 36, and a bottom protrusion 37 is formed on the bottom surface of the holding hole 35. Further, a holding piece 12 is provided protruding from a pair of sides of the opening edge of the holding hole 35 that are different from the removal hole 36, and holds the connector 5 on the upper end surface when the connector 5 is inserted into the holding hole 35. A hook portion 23 at the tip of the piece 12 is adapted to be locked. Thus, the connector 5 is inserted into the holding hole 3.
By inserting the connector 5 into the holding piece 12
When the connector 5 is removed from the base 6, the connector 5 is held by the removal hole 36 as shown in FIG. The connector 5 can be easily removed by inserting a screw rod 38 such as a screwdriver into the hole 35 and prying the screw rod 38 with its tip in contact with a corner of the lower surface of the connector 5. Here, since the bottom protrusion 37 is formed on the bottom surface of the holding hole 35, the tip of the screw rod 38 can be inserted into the lower surface side of the connector 5, and the force from the screw rod 38 is reduced. can be effectively applied to the connector 5, and the connector 5 can be easily removed.

[Effects of the Invention] As described above, the present invention provides a connector that holds electric wires inserted through a plurality of insertion holes opened at one end of a housing with corresponding locking members, and electrically connects the electric wires to each other. and a base to which multiple connectors are fixed, so that the wires can be reliably and easily connected to each other by simply inserting the wires into the connectors. Since it is fixed on one base, it has the advantage that multiple connectors can be fixed at once, and it is easy to fix the connector to a wall etc., and furthermore, the connector can be fitted into the base. A holding hole to be held is formed, a pair of opposing sides of the holding hole are recessed to form a removal hole, a bottom protrusion is formed at the bottom of the holding hole, and a connector is fitted into the holding hole. A part of the bottom part of the connector is supported by the bottom projection, and a gap is formed between the other part of the bottom part of the connector and the bottom of the holding hole,
The connector can be installed by fitting it into the holding hole because the space is in communication with the removal hole, and when removing the connector from the base, the bottom of the connector and the bottom of the holding hole can be connected through the removal hole. The advantage is that the connector can be easily removed by inserting a screwdriver-like rod into the gap formed between the two and prying it up with the tip of the rod in contact with the bottom corner of the connector. In addition, since multiple connectors can be attached and detached from the base in this way, the number of connectors can be used depending on the connection status between the electric wires, and the It can easily accommodate various connection states.
