Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically a wire harness with high tensile strength. Background Technology

[0002] A wire harness is an assembly that consists of copper contact terminals (connectors) crimped to wires and cables, and then covered with an insulator or an outer metal shell. The wire harness is widely used in the automotive, communications, and other fields.

[0003] A search revealed that patent CN220440023U discloses a compact, pull-out resistant medical wire harness. This harness comprises a first wire harness head and a second wire harness head, two sets of L-shaped rods, a vertical rod, a connecting sleeve, an elastic snap-fit ​​piece, and an arc-shaped groove. When the first wire harness head is inserted into the second wire harness head, the elastic snap-fit ​​piece engages with the arc-shaped groove, thus connecting the first and second wire harness heads. This facilitates the connection and use of the two wire harness bodies.

[0004] While the above solution can lock the first and second wire harness heads to prevent them from pulling apart, the connection mechanism is too complex, costly, difficult to manufacture, and inconvenient to operate. Furthermore, the solution does not address the pull-out resistance between the wires and the wire harness heads. Therefore, we propose a wire harness with high tensile strength. Utility Model Content

[0005] The purpose of this invention is to provide a wire harness with high tensile strength to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high tensile strength wire harness includes a cable and a connector assembly installed at the end of the cable. The connector assembly includes a male plug and a female plug. One end of each male plug and female plug is integrally formed with a sleeve, which is fixedly fitted onto the end of the cable. A metal block is provided inside each male plug and female plug. A tensile rope is provided inside the cable. The tensile rope passes through the male plug or female plug and is fixedly connected to the corresponding metal block. A slot is opened at the end of the male plug away from the sleeve. Multiple conductive rods are fixedly inserted into the slot and are fixedly connected to the wires of the cable. A protrusion is integrally formed at the end of the female plug away from the sleeve. Multiple conductive sleeves are installed on the end face of the protrusion. The conductive sleeves are adapted to the conductive rods and are fixedly connected to the corresponding wires of the cable. Two slots are symmetrically opened on both outer walls of the male plug. Locking mechanisms are installed on both outer walls of the female plug at the corresponding positions of the slots. The locking mechanisms are adapted to the slots.

[0008] As a further embodiment of this utility model: the cable includes several conductors, the outer walls of which are covered with an insulating layer, and the outer sides of the several insulating layers are collectively covered with an outer insulating sheath. The tensile rope passes through the end face of the outer insulating sheath, and the sleeve is fitted on the outer insulating sheath and is fixed by thermal fusion.

[0009] As a further embodiment of this utility model: multiple opening slots and claws are formed on the outer peripheral wall of the conductive sleeve by stamping, and the claws are biased towards the inner side of the conductive sleeve.

[0010] As a further embodiment of this utility model, a sealing ring is embedded in the outer wall of the protrusion.

[0011] As a further embodiment of this utility model: the locking mechanism includes a connecting rod, one end of which is fixedly connected to a locking block, the locking block being adapted to a locking groove, a connecting seat being fixedly connected to the outer wall of the connecting rod, mounting grooves being provided on both sides of the outer wall of the female plug corresponding to the connecting seat, a pin being fixedly passed through the outer wall of the cable corresponding to the mounting groove, the connecting seat being rotatably sleeved on the corresponding pin, a spring being provided in the mounting groove, the spring abutting against the connecting rod, and the spring and the locking block being located on both sides of the connecting seat respectively.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model has a simple structure and is easy to manufacture. By setting metal blocks inside the male and female plugs and fixing the metal blocks to the anti-tension rope of the cable, when the cable is subjected to strong pulling, the axial force it experiences will be transmitted to the metal blocks along the anti-tension rope, thereby effectively preventing the cable from detaching from the plug due to strong pulling. When connecting the male and female plugs, the protrusion of the male plug is inserted into the slot so that the conductive sleeve is fitted on the conductive rod. Then, the locking mechanism is engaged with the corresponding slot to lock the male and female plugs. The operation is simple and convenient. Attached Figure Description
