and a contact holding portion 16 are formed.

The guide pins 12a and 12b are connected to the guide socket lla.
, llb and contact holding portion 14.16 (fitting groove 13
．． 15), and this is to facilitate the fitting operation of the housing 10, which will be described later.

In the present invention, two housings 10 having exactly the same configuration are used as a pair of housings,
In addition, in its use, as shown in FIGS. 2 and 3, one of the two housings 10 is arranged so that the upper and lower stages are symmetrical to the other. In this arrangement, the guide pins 12a, 12b and the guide socket lla on the left side in FIGS.
, llb and a guide socket llb on the right side,
lla and the guide pins 12b and 12a are respectively fitted, and the contact/holding part 16, fitting groove 15, contact holding part 14, fitting groove 13 on the left side, and the fitting groove 13, contact on the right side. Child holding part 14 and fitting groove 15
, and the contact holding portion 16 are fitted into each other (see FIGS. 4 to 7).

As shown in FIGS. 4 to 6, the guide pins 12a and 12b on the left side have a female contact 18 connected to the electric wire 17, and a guide socket 11a.

A male contactor 20 connected to the electric wire 19 is loaded in each of the terminals 11b. Furthermore, the guide sockets llb and lla on the right side are loaded with a male contact 22 connected to an electric wire 21, and the guide pins 12b and 12a are loaded with a female contact 24 connected to an electric wire 23, respectively. .

As shown in FIG. 7, the contact holding parts 14 on the left and right sides
．． Connected to 16 are hermaphroditic contacts 27 and 28 which are respectively connected to electric wires 25 and 26. Contact 27°28
are hermaphroditic, and their contact surfaces have an elastic leap shape, so they can ensure reliable contact with each other with low contact force.

As understood from the foregoing, the guide sockets lla, llb, guide pin 12a, and guide sockets lla and llb of the housing 10 are of the same type and are arranged so that the upper and lower stages are symmetrical.
12b and the contact holding part 14.16, the contact 22
, 20.18.24 and 27.28 are respectively loaded to form a pair of connectors.

In such a connector, fitting starts from the state shown in FIG. 3, and the fitting is completed in the state shown in FIGS. 6 and 7. Here, it should be noted that, as understood from FIG. 2 and as described above, the guide pins 12a, 12b are connected to the guide sockets lla, ll.
b and contact holding part 14.16 (fitting groove 13.15
When the housings 10 of the pair of connectors are fitted together, first, the guide sockets 1b and 1a facing each other and the guide pins 12a and 12b are fitted together, After this fitting progresses halfway, the fitting groove 13.15 and the contact holding portion 16.14 that face each other start fitting. This means that
It is shown that these guide sockets and guide pins perform the positioning function while guiding the fitting position prior to the fitting between the fitting groove and the contact holding portion. therefore.

When a pair of housings 10 are fitted together, the contact holding portions 14 and 16 of one housing may collide with the contact holding portions 16 and 14 of the other housing due to misfitting, and the contact portions of one housing may collide. Unreasonable impact deformation and damage between the contacts 27 and 28 and the contacts 28 and 27 of the other housing can be prevented.

In FIGS. 1, 4 to 6, the housing lO

has. One of the pair of housings 10 is attached to a stationary part such as a device (not shown) with only the bushing 30 fixed, and the other housing is attached to a movable part (drawer) that slides on the stationary part. Only the bushing 30 can be fixed and installed. This allows the housings to be mounted to accommodate misfitting of the housings due to slight positional errors.

In the present invention, the guide sockets lla, llb,
Guide pins 12a, '12b and contact holding part 14
．． There is no particular limitation as to what kind of contactor is loaded in 16. However, it is suitable to use a contact with a relatively large current capacity in the guide socket and the guide pin, and a contact with a relatively small current capacity in the contact holding part.

〔Effect of the invention〕

According to the present invention, in a connector having a guide socket and a guide pin in the housing, the guide socket and the guide pin are also loaded with contacts and used as an electrical connection part of the connector. Therefore, for example, when used for equipment such as a copying machine that requires an electrical connection part with a relatively large current capacity and an electrical connection part with a relatively small current capacity, the former connection part may be a guide socket or a guide. You can use pins. Therefore, compared to the case of using a conventional connector in which the former connection part and the latter connection part are independent, the installation space occupied by the connector can be saved.

In addition, in this case, according to the connector of the present invention, since the guide socket and guide pin are arranged on both sides of the housing, even if a strong current flows through the contacts loaded therein, the temperature rise will be small. Side effects occur.

Further, since the guide pin projects further forward than the guide socket and the contact holding portion, it is extremely easy to fit the pair of connectors together.

Furthermore, since the pair of housings are formed to have exactly the same shape, only one type of mold is required, which is extremely advantageous in terms of economy and management.
