Abstract

PURPOSE:To make possible fitting even in small space and connector-fitting simultaneous with assemblage by disposing a connection terminal face of one connector adjoining a contact of the other connector and automatically regulating the position of the terminal touching the contact. CONSTITUTION:A first connector 1 and a second connector 2 are combined together. Then, a pin 12 of a freely slidable terminal frame 13 moves along a long hole 11 of the base of connector 1, guided by a guide groove 21 of the connector 1, guided by a guide groove 21 of the connector 2. Touching position of a contact terminal 24 of the connector 2 and of a plate terminal 15 of the connector 1 are thus automatically regulated, so that the terminal 24 and the terminal 25 touch mutually in face. Due to this constitution, the contact is fitted even in a narrow space without regulation and the perfect fitting of the connector simultaneously with assemblage is easily attained. A face-contact type connector, not involving blind work, is thus obtained.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surface contact type connector, and more particularly to a surface contact type connector used for connecting electric wires in a narrow place such as an automobile door.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, various parts are incorporated in a door of an automobile, and various functional parts,
For example, an electric component such as a window switchgear and an electric wire for supplying the electric power, for example, a wire harness a are usually attached to the door panel A side, and a switch block b and a courtesy lamp for controlling them are provided inside the door panel A. It is provided on the side of the door trim B attached to the side. The interconnection between these electrical components and switches is made by coupling the first connector 1 attached to the door panel A side and the second connector 2 attached to the door trim B side when assembling the door. It has become.

Such connectors are usually connected to each other at the same time when the door trim is attached to the door panel, but the connectors are not always completely fitted only by attaching the door trim. . Therefore, after attaching the door trim to the door panel, a method has been adopted in which a hand is inserted through the partial opening provided in the door trim to completely join the incompletely joined connector and to fix it so that it will not easily come off. .

Further, conventionally, such a door has been used as a connector in which a male terminal and a female terminal, which are axially opposed to each other, are inserted and attached. Not only cannot be installed vertically to the surface of the door, but it also has to be installed within a range that is within reach, which poses a problem that the installation position is restricted. Further, there is a problem that the work for fitting the connector, which is inserted at the same time as assembling the door at the same time as the semi-coupled state, is more completely fitted, and it is a blind work and the workability is poor.

[0005]

SUMMARY OF THE INVENTION Therefore, the present invention is intended to solve the above problems, and can be installed in a narrow space without any restriction, and moreover, a connector such as a door panel or a door trim can be installed. It is an object of the present invention to provide an improved electrical connector in which the complete fitting of the connector can be easily achieved at the same time as the assembling of the members, and a blinding operation is not required. In order to achieve such an object, the side surface of the connection terminal of one connector is configured to come into contact with and separate from the contact of the other connector, and the position of contact with the contact of the terminal is automatically regulated and the contact resistance is lowered. It was decided to provide a connecting terminal guiding means that can be suppressed.

[0006]

This problem is solved by a base body in which side plates having guide long holes parallel to the bottom face are provided upright on the left and right sides, and the long holes are slidably mounted on the base body. A first connector provided with a terminal frame body which is provided with a pin piercing through and projecting outwardly symmetrically and a flat plate terminal fixed in parallel to the upper surface of the terminal frame body, and an open end A socket body in which side plates having pin guide grooves for guiding the pin toward the bottom surface in the vicinity of the end portion and the end portion and in the middle portion and in the oblique direction are provided upright on both left and right sides, and a socket body of the socket body. This can be achieved by the surface contact type connector of the present invention, which is a combination of the second connectors provided with the contact terminals protruding from the bottom surface.

Further, in such a surface contact type connector, by forming a pin locking means at the bottom of the pin guide groove, it is possible to prevent the pin from being easily disengaged from the completely fitted state.

[0008]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A surface contact type connector of the present invention will be described with reference to the drawings. In the figure, reference numeral 1 is a first connector attached to the door panel A side. A terminal frame 13 is provided slidably provided with pins 12 penetrating and projecting outwardly symmetrically on both left and right sides. On the terminal frame 13, a terminal of an electric wire 14 is fixed. A plurality of rectangular flat terminals 15 are arranged and fixed in parallel with the bottom surface of the base body 10, that is, the surface of the terminal frame body 13. Therefore, the flat terminal 15 can be freely advanced and retracted in parallel with the end of the electric wire 14 in parallel with the bottom surface of the base 10 within a range limited by the elongated hole 11.

Reference numeral 2 denotes a second connector attached to the door trim B side, which has a side plate having a pin guide groove 21 for fitting and guiding the pin 12 upon fitting with the first connector 1. The socket body 20 is provided on both the left and right sides so as to face each other. A plurality of contact terminals 24 made of elastic metal pieces are provided on the upper surface of the socket body 20.
Are projected in an array corresponding to the flat terminals 15. The pin guide groove 21 is provided in the first connector 1
When the plugs are inserted into the socket-shaped second connector 2 from the direction perpendicular to the bottom surfaces while keeping the bottom surfaces parallel to each other, the flat plate-shaped terminals 15 initially face the contact terminals 24 protruding on the bottom surfaces. Is formed so that the pin 12 can be guided so as to come into contact with the bottom face while being guided in a diagonal direction and finally press the contact terminal 24 in the vertical direction again.

A pin engaging arm 22 is provided at the bottom of the pin guide groove 21, that is, at the end of the pin guide groove 21 so as to project inwardly of the pin guide groove 21.
Is engaged with the pin locking arm 22 to prevent the first connector 1 inserted into the second connector 2 from falling off. The tip portion of the pin 12 that engages with the pin locking arm 22 is formed in a shape suitable for achieving reliable locking. Further, a locking projection 23 is provided on the edge of the opening of the socket body 20 to prevent the tip of the inserted terminal frame body 13 from falling off from the socket body 20.

The surface contact type connector of the present invention is mounted so as to face the surface of the door panel A and the surface of the door trim B which are opposed to each other, and the mounting positions of the first connector 1 and the second connector 2 are the fitting of the door trim B. It is necessary to decide in advance in consideration of the joint position. As shown in FIG. 3, for example, the clamp 3 projecting from the surface of the door trim B is inserted into the mounting hole 4 provided in the surface of the door panel A so that the door trim B can be mounted and fixed to the door panel A. If so, the connector coupling operation can be performed at the same time as the door trim B is attached.

[0012]

In the surface-contact type connector of the present invention configured as described above, when the door trim B is mounted on the surface of the door panel A, the first connector 1 and the second connector 2 are placed in a position facing each other, and the pin 12 is It is located near the entrance end of the pin guide groove 21. Therefore, the door trim B is replaced by the door panel A
When the pin 12 is pressed toward, the pin 12 is fitted into the inlet end of the pin guide groove 21, is inserted, is guided by the pin guide groove 21 to reach the bottom, and is engaged and fixed with the pin locking arm 22.
At that time, the terminal frame body 13 of the first connector 1 moves in parallel with the bottom surface of the base body 10 in accordance with the movement of the pin 12, and the flat plate terminal 15 slides while contacting with the contact terminal 24 and then crimped thereto. At the same time, the tip portion of the terminal frame body 13 is also locked and fixed to the locking projection 23, and complete fitting is achieved.

The surface-contact type connector of the present invention thus fits completely by simply pressing a pair of connectors from each other in a direction perpendicular to the surface of the terminals, but the mounting surfaces of the connectors should be parallel to each other. It works exactly the same wherever it is installed. Even if an oxide film or other foreign matter that interferes with conduction adheres to the contact portion of the terminal, the flat terminal slides while contacting before it is crimped to the contact terminal, so the foreign matter is eliminated. A good connection state with low resistance can be obtained.

[0014]

Since the surface-contact type connector of the present invention is constructed as described above, it has a small thickness, a short insertion length, can be mounted between narrow wall surfaces, and can be pressed with a small force. Only then can a reliable electrical connection be achieved. Therefore, when the surface contact type connector of the present invention is used for assembling a vehicle door, it is possible to fit the door trim to the door panel and simultaneously complete the electrical circuit connection at the same time, thus eliminating the conventional blind work. Became possible.
