Description

Technical Field

[0001] The utility model belongs to the technical field of wire harnesses, and in particular relates to a high-strength traction high-voltage wire harness. Background Art

[0002] In the existing Chinese patent database, a patent named "a wiring harness" is disclosed, with application number CN201822127781.7 and application date 2018-12-18. The device includes several connecting wires and connectors arranged at both ends of the connecting wires. The connecting wires include a conductor layer and an insulating layer wrapped outside the conductor layer. The insulating layer is wrapped with a buffer layer. The buffer layer is evenly provided with several grooves in the axial direction. A reinforcement ring is arranged in the groove. The depth of the groove is the same as the thickness of the reinforcement ring. A light-transmitting layer is arranged outside the buffer layer. A plurality of reinforcement ropes are evenly arranged in the space between the buffer layer and the light-transmitting layer. A light-emitting module is arranged between adjacent reinforcement ropes. The light-emitting module is connected to the connectors at both ends. A plurality of connecting grooves are evenly arranged in the axial direction of the light-transmitting layer. A connecting ridge is formed between adjacent connecting grooves. A plurality of partition grooves are arranged on the connecting ridge. At least two connecting grooves are embedded with a plurality of strapping belts, which greatly improves the anti-pressure and anti-pulling capabilities; and can provide a light-emitting reminder of the use status. It will not be entangled and knotted; multiple connecting wires are convenient to bundle, and the wiring harness can also be conveniently and quickly fixed to external equipment and the like.

Therefore, this article aims to propose a high-strength traction high-voltage wiring harness, which completes the locking connection between the female connector and the sub-connector by setting a sub-sleeve and a female sleeve that are screwed outside the female connector and the sub-connector to prevent them from falling off.

[0009] As a preferred solution, a plurality of the clamping grooves are arranged along the axis of the female connector.

[0010] As a preferred solution, both the sub-casing body and the main casing body are provided with a neck for passing the wire, and an elastic rubber sleeve is attached to the inner surface of the neck.

[0011] Compared with the prior art, the utility model has the following beneficial effects: due to the locking connection between the sub-sleeve and the mother sleeve, the mother connector and the sub-connector can be prevented from loosening relative to each other, thereby improving the safety of the wiring harness during use.

[0014] In the figure: 1 wire, 2 sub-connector, 3 female connector, 4 sub-housing, 5 female housing, 6 limit ball head, 7 slot, 8 blind hole, 9 slider, 10 compression spring, 11 inner flange, 12 column, 13 neck, 14 elastic rubber sleeve. DETAILED DESCRIPTION

[0015] The technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0016] like Figure 1-2As shown, a high-strength traction high-voltage wire harness includes a conductor 1 with a circular cross-section, one end of the conductor 1 is connected to a sub-connector 2, and the other end is connected to a female connector 3, the outer shell of the sub-connector 2 is connected to a sub-housing 4, and the outer shell of the female connector 3 is connected to a female housing 5, and a plurality of limit ball heads 6 are elastically connected to the outer peripheral surface of the free end of the sub-housing 4, and each limit ball head 6 is radially evenly distributed with the central axis of the sub-connector 2 as the axis, and the free end end surface of the female housing 5 is provided with an inner hole, and a slot 7 for engaging with the limit ball head 6 is provided on the annular inner wall of the inner hole. A blind hole 8 is provided on the outer peripheral surface of the free end of the sub-housing 4, and a slider 9 is slidably connected in the blind hole 8, and a compression spring 10 is provided between the slider 9 and the inner bottom of the blind hole 8, one end of the compression spring 10 is connected to the inner bottom surface of the blind hole 8, and the other end is connected to the bottom of the slider 9, and an inner flange 11 is provided at the opening of the blind hole 8, and the upper surface of the slider 9 abuts against the lower surface of the inner flange 11. A column 12 is provided between the slider 9 and the limiting ball head 6. A threaded section is provided at the upper end of the column 12, and the limiting ball head 6 is screwed onto the threaded section. Several slots 7 are provided along the axis of the female connector 3. Both the sub-sleeve 4 and the female sleeve 5 are provided with a neck 13 through which the wire 1 passes, and an elastic rubber sleeve 14 is attached to the inner surface of the neck 13.

[0017] During operation, the operator inserts the female connector 3 into the female sleeve 5 and inserts the sub-connector 2 into the sub-sleeve 4. After completion, the end face of the sub-sleeve 4 is moved to face the inner hole of the end face of the female sleeve 5, so that the end face of the sub-sleeve 4 moves into the inner hole. During the movement, the limiting ball head 6 is squeezed by the inner wall of the inner hole, and the compression spring 10 is compressed until the limiting ball head 6 moves to the slot 7. The reset action of the compression spring 10 reacts the limiting ball head 6 into the slot 7, completing the locking of the sub-sleeve 4 and the female sleeve 5. Therefore, when the female connector 3 and the sub-connector 2 fall off, they need to overcome the locking force between the sub-sleeve 4 and the female sleeve 5 before they can separate from each other.
