Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a connector,
More specifically, it improves the electrical connectivity between the exposed conductor portion of the flat harness that is inserted into the housing of the connector and the terminal.

[0002]

2. Description of the Related Art Conventionally, as a means for supplying power to a combination lamp or the like of an automobile, a connector branched from a required portion of a flat harness arranged inside the automobile is fitted and connected to each lamp or the like. There is. Each of the connectors is connected to the flat harness by branching and connecting the conductor exposed by peeling off one surface of the intermediate portion of the flat harness and the terminal in each connector.

More specifically, as shown in FIG. 11, the connector 1 holds the upper and lower surfaces of the flat harness 4 by a frame-shaped sealing material 3 having a center hole 3b formed in the vertical direction. A part of the lower surface of the flat harness 4 exposed at the center hole 3b of the sealing material 3 is peeled off to expose the conductor 4a. The lower sealing material 3 is housed in the annular recess 6b of the housing 6, the terminal 5 is housed in the terminal housing chamber 6a at the center of the housing 6, and the projection 5a at the upper end of the terminal 5 is located in the central hole 3b of the sealing material 3. The exposed conductor 4a of the flat harness 4 is pressed and brought into contact with the conductor 4a, and the cover 2 is covered from above from above with the seal material 3 interposed therebetween to be locked and fixed to the housing 6.

[0004]

However, as shown in FIG.
As shown in, since the conductor 4a is exposed by previously peeling off the insulating coating 4b on the contact surface of the flat harness 4 with the terminal 5, an oxide film M, an oil film, or the like is attached to the conductor 4a. Exposed conductor 4a and terminal 5 of flat harness 4
There is a problem that the electrical connection with the projection 5a is blocked by the oxide film M and the like, and the electrical connection reliability is reduced.

The present invention has been made in view of the above problems, and an object thereof is to improve reliability of electrical connection between an exposed conductor and a terminal of a flat harness.

[0006]

In order to solve the above-mentioned problems, the present invention firstly requires that a flat harness in which both surfaces of a conductor are covered with an insulating coating is penetrated between a housing and a cover in an orthogonal direction. A connector for branching connection in which a part of an insulating coating on the housing side of a flat harness is peeled off to expose a conductor, and a tip end surface of a terminal housed in the housing is brought into contact with the exposed conductor portion from an orthogonal direction. While holding the flat harness through the cover, the cover mounting portion of the outer peripheral wall of the housing and the outer peripheral wall of the cover are formed into a cylindrical shape, and the cover is put on the housing and rotated relatively to each other. Locking means for fixing is provided, and when the cover is locked and fixed to the housing, the cover is relatively rotated to prevent the terminal from contacting the exposed conductor portion. By moving it provides a connector which is characterized in that it is configured to wipe the surface of the conductor exposed portion.

With the above construction, even if the conductor exposed portion exposed by peeling off the insulating coating on the lower surface of the flat harness is covered with an oxide film or an oil film, the cover is locked to the housing. When fixed, the terminals move relative to the conductor exposed portions of the flat harness while being in contact with each other, so that the oxide film and the like can be automatically wiped by the terminals. The parts can be surely brought into contact with each other to improve electrical connection reliability.

A substantially L-shaped guide groove is provided on the outer surface of the cover mounting portion of the housing, and a locked portion is provided at the end of the guide groove, while a locking piece is projected on the inner surface of the outer peripheral wall of the cover. A structure in which the cover is rotated with respect to the housing while sliding the locking piece in the guide groove, and the locking piece is locked to the locked portion to lock and fix the cover to the housing. I am trying.

That is, by guiding the locking piece of the cover into the guide groove of the housing in an L-shape, the cover can be rotated relative to the housing simultaneously with the locking operation. . Since the locking piece is locked by providing the locked portion at the end of the guide groove, the cover does not come off after locking.

The tip contact surface of the terminal, which comes into contact with the exposed conductor of the flat harness, is eccentric from the center of rotation.

In the case where the number of the terminal accommodating chambers in the housing is an odd number, when the terminals accommodated in the central terminal accommodating chamber coincide with the center point of the rotation, the central terminal rotates at the center point. However, since it does not move, the effect of wiping off the oxide film, oil film, etc. may be weakened.However, with the above configuration, all the terminals are eccentric from the center point in advance. The flat harness moves while contacting the exposed conductor portion, and the effect of wiping the oxide film or the like can be reliably obtained.

Secondly, the present invention secondly inserts the end of the flat harness in which both sides of the conductor are covered with the insulating coating in the orthogonal direction between the housing and the cover, and the insulating coating on the housing side of the flat harness is provided. A connector in which a conductor is exposed by peeling off a part of the conductor, and a tip of a terminal housed in a housing is brought into contact with the conductor exposed portion from an orthogonal direction for branch connection, and the flat harness is held in the cover. At the same time, the cover is provided with a locking means for fixing while sliding in a direction orthogonal to the axis of the housing, and the cover is relatively slid when the housing is locked and the conductor exposed portion is fixed. We also provide a connector characterized in that the surface of the conductor exposed portion is wiped by moving while contacting the terminal. .

With the above structure, when the cover is locked to the housing, the terminal relatively slides while contacting the conductor exposed portion of the flat harness, thereby removing the oxide film and the like. Wiring can be automatically wiped by the terminal, and the terminal and the conductor exposed portion can be surely brought into contact with each other to improve the electrical connection reliability.

The cover has a pair of slide frames projecting downward from both sides of the upper surface of the cover, and locking pieces projecting from the inner surfaces of the slide frames, while the outer surfaces of the cover mounting portion of the housing are substantially covered. An L-shaped guide groove and a substantially inverted L-shaped guide groove are provided so as to face each other, and a locked portion is provided at the end of each guide groove, and the inner surface of each slide frame and the guide groove are provided. Is parallel to the outer surface of the cover mounting portion having, and slides the cover with respect to the housing while guiding the locking piece in the guide groove,
By locking the locking piece to the locked portion, the cover is locked and fixed to the housing.

That is, by guiding the locking piece of the cover to the guide groove of the housing, the cover mounting portion having the slide frame and the guide groove are parallel to each other. It is possible to slide it with respect to the housing. Since the locking piece is locked by providing the locked portion at the end of the guide groove, the cover does not come off after locking.

In both the first and second inventions, the cover is provided with a spring accommodating portion at a position facing the terminal accommodating portion of the housing to accommodate the spring, and the spring is the flat harness. By pressing the upper surface, the contact stability between the terminal and the exposed conductor of the flat harness is increased.

With the above structure, not only can the exposed conductor portion of the flat harness and the terminal be in stable contact after the connector is assembled, but also when the cover is rotated or slid relative to the housing. Since the spring presses the flat harness against the terminal, the oxide film or the like covering the exposed conductor portion can be wiped more strongly by the terminal.

Further, the housing is provided with a frame-shaped sealing material surrounding a contact portion between the terminal and the conductor exposed portion of the flat harness, and / or a sealing material for pressing the flat harness on the cover. I have it.

Since the contact portion between the terminal and the exposed conductor portion is exposed, it is possible to prevent water or the like from entering the contact portion by surrounding the contact portion with the frame-shaped sealing material as described above. Although the sealing material is waterproof only on the terminal side, it is more preferable to provide the sealing material on the cover side and sandwich the flat harness between the upper and lower sealing materials. The flat harness used in the connector is preferably formed by laminating both surfaces of flat conductors arranged in parallel with insulating films.
