Description

Technical Field

[0001] This utility model relates to the field of cable and cable components, specifically a wire harness assembly with a sealing structure at the wire threading position. Background Technology

[0002] A wire harness is a combination of multiple cables that can transmit electrical energy / signals between two or more electrical / electronic devices and can also ground electrical / electronic devices. Therefore, wire harnesses are widely used in various electrical and electronic devices.

[0003] In the prior art, electrical / electronic equipment is often integrated into a chassis / rack (such as a power distribution cabinet, control cabinet, server cabinet, and battery compartment). Obviously, the wiring harness needs to pass through the chassis / rack to connect to the electrical / electronic equipment. Therefore, it is usually necessary to open a cable pass hole in the chassis / rack.

[0004] Some electrical / electronic equipment requires waterproof sealing. While cable glands can be installed at the cable passage holes of the chassis / rack to achieve waterproof sealing, when multiple cables need to pass through the chassis / rack, a cable gland must be installed for each cable. This obviously increases the material and assembly costs of the equipment, as well as its weight and size, and also causes inconvenience in subsequent inspection and maintenance. Alternatively, multiple cables can be integrated into a cable harness and passed through the cable passage holes of the chassis / rack together, with sealant filled at the passage holes. This can also achieve waterproof sealing, but there are certain gaps between the cables and between each cable and the passage hole. It is difficult for the sealant to fill all these gaps individually, and there is a risk of sealant aging and failure. The inherent problem of inconvenience in subsequent inspection and maintenance still exists.

[0005] In conclusion, how to provide a waterproof and reliable sealing structure for the cable routing locations of the chassis / rack that is also easy to inspect and maintain has become an urgent problem to be solved. Utility Model Content

[0008] In the above technical solution, one end of the porous sealing member is formed with an inlet portion; the inlet portion of the porous sealing member, from its root to its end, forms a structure with a gradually narrowing diameter.

[0009] In the above technical solution, the porous sealing member has a stop rib formed on the other side relative to the inlet portion; and, the porous sealing member has a sealing mating portion formed between the inlet portion and the stop rib; in the porous sealing member, the root diameter of the inlet portion is D1, the diameter of the sealing mating portion is D2, and the diameter of the stop rib is D3, then: D3>D2, and D1>D2.

[0010] In the above technical solution, the porous sealing component is one of the following materials: silicone, rubber, flexible plastic, and composite material.

[0011] In the above technical solution, the wire harness assembly also includes a wire harness outer sheath for covering each of the cables.

[0012] In the above technical solution, the wire harness assembly with a threading position sealing structure of this utility model also includes a clamping member; the clamping member is sleeved on the outer sheath of the wire harness assembly and is used to tighten the outer sheath of the wire harness and each of the cables.

[0013] In the above technical solution, at least one end of the wire harness assembly is provided with a connector.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The wire harness assembly with a wire passage sealing structure of this utility model allows each cable of the wire harness assembly to pass through the sealing wire passage hole of the multi-hole sealing member in an interference fit manner.

It provides a waterproof and reliable sealing structure for the wire passage position of the chassis / cabinet, which is convenient for inspection and maintenance. It can also effectively prevent the wire harness assembly (especially the cables) from slipping or dislodging. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This embodiment provides a wire harness assembly with a wire threading position sealing structure, which can transmit electrical energy / signals between two or more electrical / electronic devices, and / or can enable the grounding of electrical / electronic devices.

[0021] Please see Figures 1-3 The wire harness assembly with a threading position sealing structure in this embodiment includes a wire harness assembly 1 and a porous sealing member 2.

[0022] The wire harness assembly 1 includes at least a plurality of cables 11, which can be power lines or signal lines, and is covered with an outer sheath for insulation and signal shielding.

[0023] The porous sealing component 2 is elastic. Specifically, the porous sealing component 2 is made of one of the following materials: silicone, rubber, flexible plastic, and composite material, which makes it elastic. Furthermore, the porous sealing component 2 is an integrally injection molded structure.

[0024] The porous sealing component 2 has several axially penetrating sealing wire holes 21. In this embodiment, all the sealing wire holes 21 are round holes. The sealing wire holes 21 can be integrally injection molded with the porous sealing component 2, or they can be obtained by machining.

[0025] Each cable 11 of the wire harness assembly 1 passes through the sealed wire hole 21 of the porous sealing member 2 in an interference fit manner, so that there is no gap between each cable 11 and the porous sealing member 2.

[0026] Furthermore, an inlet portion 22 is formed at one end of the porous sealing member 2; the inlet portion 22 of the porous sealing member 2 has a gradually narrowing diameter structure from its root to its end; in this embodiment, the outer edge of the cross section of the inlet portion 22 is arc-shaped, and in other possible embodiments, the inlet portion 22 can be frustum-shaped or conical.

[0027] Furthermore, the porous sealing member 2 has a stop rib 24 formed on the side opposite to the inlet portion 22; and a sealing mating portion 23 is formed between the inlet portion 22 and the stop rib 24; that is, the porous sealing member 2 is arranged sequentially along the axial direction as: inlet portion 22, sealing mating portion 23, and stop rib 24; see also Figure 3 In the porous sealing member 2, the root diameter of the inlet part 22 is D1, the diameter of the sealing mating part 23 is D2, and the diameter of the stop rib 24 is D3. Then, D3 > D2, and D1 > D2.

[0028] Furthermore, the wire harness assembly 1 also includes a wire harness sheath 12 for covering each cable 11. The wire harness sheath 12 is an insulator that can integrate each cable 11 into a single strand to improve the insulation performance and mechanical strength of the wire harness assembly 1.

[0029] Furthermore, the wire harness assembly with a wire threading position sealing structure in this embodiment also includes a clamping member. The clamping member is sleeved on the wire harness outer sheath 12 of the wire harness assembly 1 and is used to tighten the wire harness outer sheath 12 and each cable 11 to further improve the insulation performance (preventing moisture from entering the wire harness outer sheath 12) and mechanical strength of the wire harness assembly 1. In this embodiment, the clamping member is a plastic cable tie.

[0030] Furthermore, at least one end of the wire harness assembly 1 is provided with a connector 3. In this embodiment, both ends of the wire harness assembly 1 are provided with connectors 3 to enable quick connection between the wire harness assembly 1 and electrical / electronic equipment.

[0031] In this embodiment, the wire harness assembly with a wire-passing position sealing structure requires the guide portion 22 of the multi-hole sealing member 2 to be pushed into the wire-passing position of the chassis / rack after passing through the wire-passing position (usually a round hole) in the chassis / rack. (During this process, the shape of the guide portion 22 makes it easy for the multi-hole sealing member 2 to be pushed into the wire-passing position.) This allows the sealing mating portion 23 of the multi-hole sealing member 2 to be located in the wire-passing position in the radial direction. At this time, the guide portion 22 and the stop rib 24 of the multi-hole sealing member 2 abut against the inner and outer walls of the chassis / rack, respectively. In this way, there is no gap between each cable 11 of the wire harness assembly 1 and the wire-passing position of the chassis / rack. This ensures a good seal between the wire harness assembly 1 and the chassis / rack and effectively prevents the wire harness assembly 1 (especially the cables 11) from slipping or dislodging.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
