BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector assembly, and more particularly to an electrical connector assembly having a connector holder for holding two connectors in parallel.

[0002]

2. Description of the Related Art In a certain type of electromechanical device, two independent electrical connectors having a predetermined number of female contacts arranged in a row at a predetermined pitch in a length direction of a housing are provided.
Line up in rows and connect the connectors 2 in the length of the housing.
There is a need to supply such a connector because it is convenient to fit and electrically connect to a mating electrical connector having a predetermined number of male contacts arranged in a row at a pitch corresponding to the pitch.

Therefore, conventionally, a box-shaped holder having only one side surface (the rear side surface from which an electric wire extends) opened along the lengthwise direction is formed, and a connector having a female contactor on the opened side surface of the holder. There is known a connector which is arranged in two rows and fitted together and, in this fitted state, is fitted into a mating connector having a male contactor for electrical connection.

As a means to meet the above demand, it is conceivable to manufacture a connector corresponding to a combination of two connectors having female contacts. According to this, the said holding body becomes unnecessary. However, in the connector of the type in which the electric wires are pressure-connected to the contactors, either one of the electric wires is separately pressure-connected to the one row of contactors, or the electric wire is simultaneously pressure-connected to the two rows of contactors. However, with the former method, there is another
That work in a row requires the connector to be flipped over, making it unsuitable for high-speed manufacturing, and the latter method is not technical to handle with automated machines commonly used in the industry. This method is not adopted because it is difficult.

[0005]

Since the holding body has side walls facing each other along the length direction, the holding body becomes bulky by the thickness of both side walls. Therefore, it is difficult to meet the demand for reduction in size, weight, and thinness of the entire connector including the holder. Further, in a connector having a relatively large number of contacts, the holding body for fitting the contacts also becomes large and large. When both of them become long and large, the fitting and removal resistance of the connector with respect to the holding body becomes large, and in order to withstand this, it is necessary to provide a structure that further enhances the shape holding strength of both. Then, the fitting / removal resistance of the connector with respect to the holding body increases, and the operation is difficult to perform.

There is a problem that the connector is deformed when the connector is pressed to fit the mating connector due to the increase in size and size. Further, this deformation may cause prying due to the contact of the mating connector.

Furthermore, when the holding body becomes large and large, the opposing side walls along the length direction thereof are likely to warp inward.
Also in this respect, it is difficult to insert and remove the connector with respect to the holding body.

Therefore, it is an object to solve such drawbacks of the prior art.

An object of the present invention is to provide an electrical connector assembly which solves the above drawbacks.

SUMMARY OF THE INVENTION An electrical connector assembly according to the present invention has an elongated side wall having holes arranged at a predetermined pitch along the longitudinal direction and a central portion along one side of the side wall along the longitudinal direction. A pair of connector holding chambers defined by a slender intermediate partition wall that is substantially orthogonal to each other and an end wall that integrally intersects both surfaces in the vicinity of opposite ends in the length direction of the intermediate partition wall and that has locking means. A pair of connectors having a connector holder, a plurality of contacts arranged in the longitudinal direction of the side wall at the same pitch as the holes, and another locking means for engaging with the locking means; It is characterized in that the pair of connectors are mounted in the holding chamber to integrate the contactor with the hole.

[0011]

In the electrical connector assembly according to the present invention, the two connectors are integrally locked in the connector holding chamber of the connector holding body, which is defined by the side wall having the hole, the partition wall and the end wall. Therefore, the connector is securely held. Further, the connector assembly is prevented from being deformed when it is pressed, and the contacts are not twisted.

Embodiments of the present invention will be described below with reference to the drawings.

1 and 2, a connector holder (hereinafter, simply referred to as a holder) 10 and a connector 20 are shown.

The holder 10 is preferably made of a relatively soft synthetic resin, and has an elongated side wall (front side wall) 11 facing a mating connector (not shown), and a center along the longitudinal direction of the front side wall 11. An elongated partition wall 1 that is substantially orthogonal to one surface
2 and end walls 13a, 13b, 14a, 14b that integrally intersect with each other at both ends in the length direction of the front side wall 11 and the partition wall 12. The height of these end walls is 1
Height (width) of front side wall portions 11a and 11b partitioned by 2
It is formed slightly shorter than. End walls 13a, 13b
Locking means 15 projecting inward are provided at the upper edge and the lower edges of the end walls 14a and 14b. The rear side edge portion of the middle partition wall 12 facing the front side wall 11 is provided with second locking means 16 protruding in a triangular shape whose outer surface is inclined at predetermined intervals in the lengthwise direction. Contact insertion holes 17 corresponding to the arrangement pitch of the female contacts (not shown) of the connector 20 are formed near the upper and lower edges of the front side wall 11 at predetermined intervals. The male contactor of the mating connector passes through the insertion hole 17 and fits into the female contactor for electrical connection.

The connector 20 includes a housing 21. The housing 21 is made of an insulating material such as synthetic resin,
The cavities 22 are formed at the arrangement pitch of the female contacts. In FIG. 1, the cavity 22 is open on the rear side (front side) and the lower side (contact receiving surface) of the housing 21.
The female contactor is attached to the electric wire 27 by pressure contact with the female contactor, and is attached from the lower surface opening portion of the cavity 22. The engaging portion 23 formed in the rear side surface opening portion of the cavity 22 pulls the female contactor backward. Have been thwarted. The end wall 24a of the housing 21,
Ears 25a, 25b (other locking means) that engage with the inner surface of the first locking means 15 of the holding body 10 are formed at approximately the center of the outer surface of 24b. The width dimension of the housing 21 that intersects the length direction is substantially equal to the dimension between the inner surface of the front side wall 11 of the holding body 10 and the inner surface of the second locking means 16. The height of the housing 21 is substantially equal to the height of the front side wall portions 11a and 11b. Protrusions 26 are provided near both ends of the upper surface of the housing 21 to prevent the connector 20 from being mistakenly fitted and held in the holder 10 in the upside-down direction.

As shown in FIG. 3, two connectors 20 are provided.
Is directed to the upper and lower holding chambers 18a and 18b (see FIGS. 1 and 2) of the holding body 10 divided by the partition wall 12 so that the lower surface open portion of the cavity 22 of the connector faces the plane of the partition wall 12. It is held by being pushed in from the top and bottom and fitted. In this holding state, the ear portions 25a of the connector 20,
25b engages with the inner surface of the first locking means 15 of the holding body 10, and the rear side surface (front surface) of the connector 20 engages with the inner surface of the locking means 16 of the holding body 10. Therefore, the two connectors 20 are prevented from randomly moving or being pulled out in either direction. Further, in this holding state, as is clear from FIGS. 2 and 3, the holding body 10 is
The upper and lower edges of the front side wall 11, the upper edges of the end walls 13a and 13b, and the lower edges of the end walls 14a and 14b do not project from the upper and lower surfaces of the connector 20. From holder 10 to connector 20
In order to pull out, the group of electric wires 27 may be gripped and slightly twisted so that the rear side edge of the connector 20 approaches the front side wall 11 side with the front side edge of the connector 20 as a fulcrum.

As described above, the connector 20 is attached to the holder 10.
Each of the pair of end walls 13a, 13b facing each other in the length direction of the holding body, when fitted to or detached from the holding body,
14a, 14b are pushed outward by the ears 25a, 25b of the connector against the elasticity thereof to expand, and after fitting and unmating, return to the original shape.

As described above, the end wall 1 of the holder 10 is
Since 3a, 13b, 14a, 14b can be expanded,
The connector 20 can be fitted into the holding body 10 from the rear direction, but its operation is not so easy as compared with that from the up and down direction of the holding body 10. Therefore, the fitting operation from the up and down direction is usually performed. Done. Even if the upper and lower surfaces of the connector 20 are erroneously fitted and held to the holding body 10 in a direction opposite to the normal vertical direction, the projection 26 interferes with the holding and the fitting and holding cannot be performed. In addition, the second locking means 1
6 is most preferably provided on the partition wall 12 as in the illustrated example, and is sufficient to prevent rearward unintentional disconnection of the connector, but, for example, 10 and the connector 20 are relatively short, the end walls 13a. It may be provided only in a predetermined portion of 13b, 14a, 14b.

[0019]

According to the electric connector assembly of the present invention, two pieces are provided in the connector holding chamber of the connector holding body, which is defined by the side wall having the holes of the predetermined pitch, the partition wall, and the end wall. The connector is locked together with the contact and the hole positioned, so that the connector assembly can be firmly constructed with relatively few materials. Even when the connector is pressed against the mating connector for fitting, the connector is prevented from moving by the side wall of the connector holder, so that the electrical connector assembly is not easily deformed. The mating contactor is guided by the hole and is inserted only at a predetermined position, so that the electrical connector assembly is less likely to be deformed, so that the electrical connector assembly can be fitted smoothly.
