Sheath for male end of low voltage wiring harness connector for automobile

Abstract

The utility model relates to the field of automotive wiring harnesses, and specifically to a protective sleeve for the male end of a low-voltage wiring harness connector for automobiles, comprising a sleeve box that is sleeved on the male end of the connector, an inner side plate of the bottom plate of the sleeve box extending with an inner tube toward the male end of the connector, the inner tube and the plug rod at the male end of the connector forming a sleeve-type fit, and the height of the inner tube is less than or equal to the height of the sleeve box. When the above scheme is used for the male end plug-in of the low-voltage wiring harness for automobiles, each plug rod of the male end of the wiring harness can be protected to avoid the terminal being skewed or bent due to collision, and the protective effect is better; at the same time, if the male end plug rod is skewed, the plug rod can be simply corrected through the inner tube.

Description

Technical Field

[0001] The utility model relates to the field of automobile wiring harnesses, in particular to a sheath of a male end of a low-voltage wiring harness connector for an automobile. Background Art

[0002] Low-voltage wiring harnesses are important parts of automobiles, and are arranged in various parts of the vehicle. Due to the need for docking and connection of the body, doors, front and rear bumpers, engine wiring harnesses, etc., as well as the increase in automobile functions, the vehicle wiring harness requires many docking connectors. The male terminal of the connector is in the shape of a needle rod. If it is not protected during transportation, it is easy for foreign objects to enter the sheath or bump into it, causing the terminal to be skewed or the needle to bend, making it difficult to assemble in the workshop, and also affecting the performance of the connector. Poor connection can cause some functions of the vehicle off the line to fail.

[0003] The current protection measures are mostly to seal the butt ends with tape, which is not very reliable. First, the tape may be punctured during transportation. Second, the sealing tape is too strong for workers to tear off during assembly in the workshop. If it is not strong enough, it may fall off during transportation, which does not provide protection. In addition to the tape, the existing sealing protective cover has no internal structure, but is simply a flat protective cover that cannot properly fix and protect each terminal. If the terminal is skewed, it cannot be simply corrected. Utility Model Content

[0004] The utility model aims to provide a sheath for the male end of a low-voltage wiring harness connector for an automobile, which protects the plugging rod of the male end of the wiring harness and can play a corrective effect.

[0005] To achieve the above-mentioned purpose, the technical solution unique to the utility model is: a protective sleeve for the male end of a low-voltage wiring harness connector for an automobile, comprising a sleeve box that is sleeved on the male end of the connector, an inner plate of the bottom plate of the sleeve box extending with an inner tube toward the male end of the connector, the inner tube and the plug rod at the male end of the connector forming a sleeve-type fit, and the height of the inner tube is less than or equal to the height of the sleeve box.

[0006] When the above solution is used for the male end plug-in of the low-voltage wiring harness for automobiles, it can protect each plug rod of the male end of the wiring harness, avoid the terminal being skewed and the pin being bent due to collision, and the protection effect is better; at the same time, if the male end plug rod is skewed, the plug rod can be simply corrected through the inner tube.

[0010] The technical solution of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0011] A protective cover for the male end of a low-voltage wiring harness connector for an automobile, characterized in that it includes a sleeve box 10 sleeved on the end of the male end A of the connector, an inner plate of a bottom plate 11 of the sleeve box 10 extending toward the male end A of the connector with an inner tube 20, the inner tube 20 and the insertion rod A1 at the end of the male end A of the connector form a sleeve-type fit, and the height of the inner tube 20 is less than or equal to the height of the sleeve box 10.

[0012] like Figure 3 As shown, the inner tube 20 in the sleeve 10 is coaxially arranged with the insertion rod A1 on the male end A of the connector, and the sleeve 10 is connected with the end of the male end A of the connector, and the pin A1 is inserted into the tube cavity of the inner tube 20. The inner wall of the inner tube 20 covers the rod body of the insertion rod A1 to maintain the connection between the sleeve and the male end A of the connector, and due to the guiding effect of the inner tube 20, individual crooked pins A1 will be corrected accordingly.

[0013] In order to facilitate the insertion of the plug rod A1, the inner tube 20 includes a straight tube section 21 close to the bottom plate 11 of the sleeve 10 and a flared tube section 22 close to the male end A of the connector and with a gradually increasing diameter. That is, the diameter of the inner tube 20 is larger at the tube mouth, which is not only convenient for the plug-in connection between the two, but also can be "bent" back at the flared tube section 22 even if the rod end of the individual plug rod A1 deviates from the axis. As the insertion action gradually deepens, the rod end of the plug rod A1 enters the straight tube section 21, and the crooked plug rod A1 is also corrected.

[0014] The overall shape of the sleeve 10 is rectangular, because the cross section of the male end A of the connector is generally rectangular. The number of the inner tubes 20 corresponds to the number of the male ends A of the connector. The lengths of the inner tubes 20 are the same overall. The gaps between the ports of the horn tube sections 22 of the inner tubes 20 are arranged.
