Description

  The present invention relates to a connector for connecting a lamp and a flat cable used in an automobile or the like, and a connection structure using the same.

  In recent years, flat cables having good space factor and large current capacity have been used for in-car wiring of automobiles or the like, compared to wire harnesses in which round electric wires are bundled. A flat cable is obtained by applying an insulating coating to a plurality of flat conductors arranged in parallel by extrusion coating or pasting of a plastic film.

  Conventionally, the following methods are known as means for connecting a lamp to a flat cable. (1) A method in which a conductor exposed portion is provided on one side of a flat cable, and a lamp contact is brought into contact with the conductor exposed portion (Patent Document 1). (2) A method of removing the insulation coating from the end portion of the flat cable to expose the flat conductor, and connecting the exposed conductor portion to the bus bar and the spring terminal supporting the lamp by welding or soldering (Patent Document 2).

Embodiment 1 FIGS. 1 to 5 show an embodiment of the present invention. In the figure, 10 is an automotive lamp, 12 is a flat cable as a wiring material, and 14 is a connector. The lamp 10 has a pair of lead portions 16. The flat cable 12 is formed by laminating, for example, a polyethylene terephthalate film from both sides to a plurality (two in the illustrated example) of flat conductors 18 arranged in parallel and applying a collective insulating coating 20.

  As shown in FIG. 1, the connector 14 includes a connector 22, a plate 24, a housing 26, a lid 28, and the like. The connector 22 is made of metal, and as shown in FIG. 2, piercing pieces 32 that pierce the flat conductor of the flat cable are formed on both sides of the connector plate 30 downward. The plate 24 is made of metal and has a slot 34 into which the tip of the piercing piece 32 of the connector 22 is press-fitted. The size of the slot 34 is set so that it cannot be easily pulled out when the tip of the piercing piece 32 is press-fitted.

  The housing 26 is made of plastic and has a recess 36 formed on the upper surface. A pair of round holes 38 for introducing the lead portion of the lamp into the recess 36 are formed on one end side of the housing 26, and a flat hole 40 for introducing a flat cable into the recess 36 is formed on the other end side. . The plate 24 is fixed to the bottom of the recess 36. The lid 28 is formed so as to fit into the recess 36 of the housing 26. The connector 22 is held by the lid body 28 so as to be slidable up and down, and is positioned at a position where the tip of the piercing piece 32 is press-fitted into the slot 34 of the plate 24. A lead portion pressing groove 42 is formed on the lower surface of the lid 28.

  Connection between the lamp 10 and the flat cable 12 using the connector 14 is performed as follows. First, as shown in FIG. 3, the flat cable 12 is introduced from the flat hole 40 into the recess 36 of the housing 26, and the lead portion 16 of the lamp 10 is introduced from the round hole 38. The flat cable 12 is positioned by the flat hole 40 and the inner wall of the recess 36 so that the flat conductor 18 is located on the slot 34 of the plate 24. The lead portion 16 is positioned by the round hole 38 so as to be positioned on the flat cable 12 in the center portion in the width direction of the flat conductor 18.

  Next, as shown in FIG. 4, the lid 28 is fitted into the recess 36 of the housing 26. As a result, the connector 22 straddles the lead portion 16 and the lead portion 16 is pressed by the pressing groove 42. The connector 22 is preferably formed in a size such that the inner surface of the piercing piece 32 is in contact with both side surfaces of the lead portion 16. Thereafter, when the connector 22 is pushed in, as shown in FIG. 5, the piercing pieces 32 pierce and penetrate the flat conductor 18 on both sides of the lead portion 16, and the penetrated portions are press-fitted into the slots 34 of the plate 24.

  Thus, the connector 22 cannot be pulled out, and the lead portion 16 and the flat conductor 18 are electrically connected via the connector 22. In this connection structure, the lead portion 16 and the flat cable 12 are sandwiched between the connector plate portion 30 and the plate 24 of the connector 22, and the piercing piece 32 of the connector 22 passes through the flat conductor 18 and the flat conductor 18. Because of the close contact, the connection state is more stable than that of contact of the contacts, and high reliability can be obtained.

Embodiment 2 FIGS. 6 and 7 show another embodiment of the present invention. FIGS. 6 and 7 correspond to FIGS. 3 and 5 of the first embodiment, respectively, and illustrations corresponding to FIGS. 1, 2, and 4 of the first embodiment are omitted. In this embodiment, the positional relationship between the connector 22 and the plate 24 is opposite to that of the first embodiment. That is, the connector 22 is inserted into the recess 36 of the housing 26 so that the piece 32 faces upward, and the plate 24 is fixed to the lower surface of the lid 28. The connector 22 is held by the housing 26 and positioned at a position where the lead portion 16 of the lamp 10 can be mounted. The plate 24 is held by the lid 28 and positioned at a position where the stab 32 is press-fitted into the slot 34. ing.

  In the case of this embodiment, the positional relationship between the lead portion 16 and the flat cable 12 is also opposite to that in the first embodiment, and the lead portion 16 introduced into the recess 36 from one end side is connected to the connector 22 as shown in FIG. The flat cable 12 arranged inside and introduced from the other end side is arranged on the connector 22. When the lid body 28 is pushed into the recess 36 in this state, the piercing piece 32 pierces and penetrates the flat conductor 18 of the flat cable 12 as shown in FIG. The Therefore, a connection state similar to that of the first embodiment can be obtained.

  Since the configuration other than the above is the same as that of the first embodiment, the same portions are denoted by the same reference numerals and description thereof is omitted.

Embodiment 3 FIG. 8 shows still another embodiment of the present invention. In this embodiment, the connector of the type of the first embodiment is made waterproof. That is, the cross-sectional shape of the portion of the housing 26 into which the flat cable 12 is introduced is made into an oval shape (or a circular shape), a groove is formed on the outer periphery thereof, and a rubber packing 44 for waterproof sealing is attached to the groove. . The rubber packing 44 protrudes from the outer peripheral surface of the housing 26 and comes into close contact with the inner peripheral surface of the lamp cover 46 when the lamp cover 46 is covered. If it does in this way, the waterproofness of the part which connected the lamp | ramp 10 and the flat cable 12 with the connector 14 can be maintained. In order to make the waterproof property more reliable, an injection hole 48 that leads to the internal space is formed in the connector 14, and a jelly-like water leakage prevention material, for example, is injected from the injection hole 48 so that the space in the housing 26 is filled. It is advisable to fill with a water-proofing material.

  Since the configuration other than the above is the same as that of the first embodiment, the same portions are denoted by the same reference numerals and description thereof is omitted.
