Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to a single-row wire harness connector. Background Art

[0002] Flexible flat cable (FFC) is a new type of data cable, which has the advantages of being soft, arbitrarily bendable and foldable, thin in thickness, small in volume, simple in connection and convenient in disassembly. The FFC cable is connected to other components through a connector to form stable data transmission.

[0003] With the development of the new energy vehicle industry, the entire industry has higher and higher requirements for the layout of the vehicle interior space and weight reduction. The FFC cable is connected through a connector. The existing FFC cable and connector are fixed by clamping, so that the FFC cable and the connector cannot ensure stable connection during actual use, affecting data transmission. The connection method between the FFC cable and the connector makes the volume and weight of the existing connector unable to meet the development needs of the vehicle. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a single-row wire harness connector with a smaller volume, lighter weight and better stability than the prior art.

[0005] To achieve the above object, the technical solution adopted by the utility model is: a single-row wire harness connector, including a housing one, a housing two, a sheath one, a sheath two, a flexible cable one and a flexible cable two. The sheath one is sleeved on the flexible cable one and is in snap-fit with the housing one. The sheath two is sleeved on the flexible cable two and is in snap-fit with the housing two. An embedding groove is provided on the side of the housing one facing away from the sheath one. A protruding end protruding away from the sheath one is provided at the bottom of the embedding groove. A conductive terminal is penetrated through the protruding end. The housing two is tubular and partially inserted between the protruding end and the embedding groove. The housing one and the housing two are in snap-fit. The conductive terminal is welded and fixed to the flexible cable one. A fixing structure one for keeping the housing one and the flexible cable one relatively fixed is provided between the housing one and the flexible cable one. The conductive terminal is in electrical contact with the flexible cable two. A fixing structure two for keeping the sheath two and the flexible cable two relatively fixed is provided between the sheath two and the flexible cable two.

[0006] With the above solution, during assembly, first sleeve the sheath one on the flexible cable one and keep the housing one and the flexible cable one relatively fixed through the fixing structure one, then snap-fix the sheath one and the housing one, then sleeve the sheath two on the flexible cable two and keep the sheath two and the flexible cable two relatively fixed through the fixing structure two, then snap-fix the sheath two and the housing two, and finally insert the housing two between the embedding groove and the protruding end and make the housing one and the housing two in snap-fit to complete the connection.

[0007] The utility model is easy to assemble, small in size, light in weight and good in stability, and can meet the needs of automobile development.

[0008] As a further configuration of the utility model, a snap-in block is provided on the inner wall of the embedding groove, an elastic arm is provided on the outer wall of the shell two, one end of the elastic arm facing the shell one is fixed to the shell two, and the elastic arm is provided with a snap-in groove that can be snap-fitted with the snap-in block.

[0009] The above scheme is adopted to facilitate the clamping and ensure the clamping effect. When disassembly is required, the end of the elastic arm away from the shell one can be pressed to complete the separation of the shell two from the shell one.

[0010] As a further configuration of the utility model, a strip-shaped positioning block is provided on the outer wall of the second shell, and a positioning groove for the positioning block to slide is provided on the groove wall of the embedding groove.

[0011] The above solution facilitates the insertion of the second housing into the embedding groove.

[0012] As a further configuration of the utility model, the second sheath is located inside the second shell, and blocks are provided on the two opposite outer walls of the second shell. The two opposite outer walls of the second sheath are provided with L-shaped spring pieces that fit with the outer walls of the second shell, and the spring pieces are provided with grooves that can form a limit with the blocks.

[0013] The above solution facilitates the clamping connection between the second sheath and the second shell. When it is necessary to disassemble and replace, the second sheath and the second shell can be separated by breaking open the spring sheet.

[0014] As a further configuration of the utility model, a limiting groove for inserting the spring piece is provided on the outer wall of the second shell, and the clamping block is arranged at the bottom of the limiting groove.

[0015] By adopting the above solution, the second sheath and the second shell can maintain a stable connection when the utility model is actually used, thereby ensuring the stability of data transmission.

[0016] As a further configuration of the utility model, a force-applying end is provided on a side of the elastic arm away from the housing.

[0017] By adopting the above solution, when the shell one and the shell two need to be separated, the force-applying end facilitates the operator to apply force to the elastic arm.

[0018] As a further configuration of the present invention, the fixing structure 1 is at least two fixing blocks arranged on the shell 1 and fixing holes arranged on the flexible cable 1 for the fixing blocks to be embedded.

[0019] As a further configuration of the present invention, the second fixing structure is a groove arranged on two opposite sides of the second flexible flat cable and a protrusion arranged on the second sheath and capable of forming a limit with the groove.

[0020] With the above solution, the structure is simple and the fixing effect is good, so that in the actual use process of the present utility model, the flexible cable one, the conductive terminal and the flexible cable two are stably connected.
