[0056] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this application will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0057] It is understood that the terms "including" and "having" and any variations thereof in the embodiments of the present application are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or components that are inherent to these processes, methods, products, or devices.

[0058] like Figure 1 As shown, the device according to the embodiment of the present application includes a relay 10 and a wiring harness 20 , and the wiring harness 20 is arranged around the relay 10 .

[0059] It is understandable that the present application does not impose any particular limitation on the device. For example, the device may be a battery pack, or other device that requires the configuration of the relay 10 .

[0060] like Figure 2 and Figure 3 As shown, the relay 10 of the embodiment of the present application includes a relay housing 100, a relay body 300, a lead-out piece 400 and a fastener 500. The relay body 300 is disposed in the relay housing 100, the static contact 310 of the relay body 300 is electrically connected to the lead-out piece 400, and the fastener 500 is used to fasten the lead-out piece 400 and the static contact 310. In one embodiment, the fastener 500 can be a screw, but is not limited thereto.

[0061] In the embodiment of the present application, the relay body 300 has a pair of stationary contacts 310 , and each stationary contact 310 is electrically connected to a lead-out member 400 .

[0062] The present application does not specifically limit the type of the relay 10 . For example, the relay 10 may be a high voltage DC relay or a common relay.

[0063] When the relay 10 is a high-voltage DC relay, the relay body 300 may include an insulating cover, a yoke plate, a moving assembly, a moving contact piece, and a magnetic circuit portion, etc. The connection relationship between the insulating cover, the yoke plate, the moving assembly, the moving contact piece, and the magnetic circuit portion may refer to the arrangement of the existing high-voltage DC relay, which will not be described here, and the wire management assembly 200 of the relay 10 will be described in detail below.

[0064] like Figures 1 to 3 As shown, the relay housing 100 of the embodiment of the present application includes a housing body 100a and a wire management assembly 200. The relay body 300 is disposed in the housing body 100a, and a portion of the static contact 310 of the relay body 300 extends out of the outer wall surface of the housing body 100a. At least a portion of the wire management assembly 200 extends out of an outer surface 110a of the housing body 100a, and the wire management assembly 200 has a wire management port 230 for the wire harness 20 to pass through, and the wire harness 20 is confined in the wire management port 230.

[0065] The relay housing 100 of the embodiment of the present application includes a shell body 100a and a wire management assembly 200. The wire management port 230 of the wire management assembly 200 can limit the wire harness 20 so that the wire harness 20 around the relay can be orderly limited in the wire management port 230 of the wire management assembly 200, making the wire harness 20 around the relay neat and orderly, thereby improving the aesthetics and safety.

[0066] like Figure 3 As shown, the housing body 100a includes a first housing 110 and a second housing 120, which are connected to form a chamber for accommodating the relay body 300. The first housing 110 and the second housing 120 can be connected by snap-fitting, but the present invention is not limited thereto.

[0067] In one embodiment, the first shell 110 is in the shape of a cuboid with an opening, and the second shell 120 is substantially in the shape of a plate. The second shell 120 is buckled to the opening of the first shell 110 .

[0068] In another embodiment, the first shell 110 and the second shell 120 are both in a rectangular shape and have an opening on one side. The opening of the first shell 110 and the opening of the second shell 120 are arranged opposite to each other, and when the opening of the first shell 110 and the second shell 120 are snapped together, a chamber for accommodating the relay body 300 is formed.

[0069] It can be understood that in one embodiment, the cable management assembly 200 is disposed in the first shell 110; in another embodiment, the cable management assembly 200 is disposed in the second shell 120; in another embodiment, part of the cable management assembly 200 is disposed in the first shell 110, and another part of the cable management assembly 200 is disposed in the second shell 120.

[0070] Next, the cable management assembly 200 is described by taking an example in which a portion of the cable management assembly 200 is disposed in the first housing 110 and another portion of the cable management assembly 200 is disposed in the second housing 120 .

[0071] like Figure 2 and Figure 3 As shown, the cable management assembly 200 includes a hook 210 and a protrusion 220, wherein the hook 210 is disposed on the second housing 120 and the protrusion 220 is disposed on the first housing 110. It is understandable that disposing the hook 210 and the protrusion 220 on the second housing 120 and the first housing 110, respectively, is more conducive to molding.

[0072] It should be noted that the present application does not specifically limit the number of hooks 210 and protrusions 220 included in the cable management assembly 200. For example, in one embodiment, the number of hooks 210 included in the cable management assembly 200 may be equal to the number of protrusions 220; in another embodiment, the number of hooks 210 included in the cable management assembly 200 is less than the number of protrusions 220; in yet another embodiment, the number of hooks 210 included in the cable management assembly 200 is greater than the number of protrusions 220.

[0073] In the embodiment of the present application, the cable management assembly 200 includes two hooks 210 and two protrusions 220 , and the orthographic projections of the two hooks 210 on the outer surface 110 a are located between the orthographic projections of the two protrusions 220 on the outer surface 110 a , but the present invention is not limited thereto.

[0074] like Figure 2 and Figure 3 As shown, the hook 210 includes a connecting portion 211, a cantilever 212 and a barb 213. The connecting portion 211 is connected to the edge of the second housing 120, and at least part of the connecting portion 211 extends out of the outer surface 110a; one end of the cantilever 212 is connected to the part of the connecting portion 211 extending out of the outer surface 110a, and the space between the cantilever 212 and the outer surface 110a of the first housing 110 forms a wire management port 230; the barb 213 is provided at the other end of the cantilever 212, and is used to stop the wire harness 20 from escaping from the wire management port 230. The cantilever 212 is made of elastic material, so that when the barb 213 is squeezed by the wire harness 20, the cantilever 212 can be deformed in a direction away from the outer surface 110a.

[0075] Specifically, when the wire harness 20 is arranged, the extrusion force formed by the wire harness 20 squeezing the barb 213 causes the cantilever 212 to deform in a direction away from the outer surface 110a. As the deformation of the cantilever 212 gradually increases, the wire harness 20 is inserted into the wire management opening 230. After the wire harness 20 is inserted into the wire management opening 230, the cantilever 212 is reset so that the barb 213 forms a stop for the wire harness 20 to prevent the wire harness 20 from slipping out of the wire management opening 230.

[0076] It can be seen that the wire management assembly 200 of the embodiment of the present application forms a semi-closed structure. After the wire harness 20 passes through the wire management opening 230, the wire harness 20 around the relay becomes neat and orderly, which improves the aesthetics and safety, and facilitates the pressing of the wire harness, which is simple to operate.

[0077] In one embodiment, the length direction of the cantilever 212 is parallel to the outer surface 110 a .

[0078] The number of hooks 210 included in the cable management assembly 200 of the present application can be one or more, and a plurality means more than two. When the number of hooks 210 is multiple, the multiple cantilevers 212 of the multiple hooks 210 extend from their respective connecting parts 211 in the same direction. In this way, the opening directions of the multiple cable management openings 230 formed between the multiple hooks 210 and the outer surface 110a are also the same, so that the wiring harness 20 can be moved in the direction opposite to the extension direction of the cantilever 212 to simultaneously engage the multiple hooks 210.

[0079] Please continue reading Figure 2 and Figure 3 The protrusion 220 is protruding from the outer surface 110a of the first housing 110 and is disposed next to the barb 213 to prevent the wire harness 20 from escaping from the wire management port 230. In the embodiment of the present application, the protrusion 220 cooperates with the barb 213 of the hook 210 to further prevent the wire harness 20 from escaping from the wire management port 230.

[0080] like Figure 3 As shown, the side wall 112 of the first housing 110 has a notch 113 , and the connecting portion 211 is disposed in the notch 113 .

[0081] like Figure 4 As shown, the barb 213 has a first guide surface 213a, and the protrusion 220 has a second guide surface 221. When the wire harness 20 presses the barb 213, the first guide surface 213a is used to guide the wire harness 20 to be clamped into the wire management port 230, and the second guide surface 221 is used to guide the wire harness 20 to be clamped into the wire management port 230.

[0082] In the embodiment of the present application, the barb 213 is provided with a first guide surface 213 a , and the protrusion 220 has a second guide surface 221 , so that the operator can insert the wire harness 20 into the wire management opening 230 with less effort.

[0083] It is understandable that the cable management assembly 200 is not limited to the structure of the hook 210 and the protrusion 220, as long as it can allow the wire harness to pass through and limit the wire harness.

[0084] In summary, the relay housing 100, the relay 10 and the device according to the embodiment of the present application have at least the following advantages and beneficial effects:

[0085] The relay housing 100 of the embodiment of the present application includes a shell body 100a and a wire management assembly 200. The wire management port 230 of the wire management assembly 200 can limit the wire harness 20 so that the wire harness 20 around the relay can be orderly limited in the wire management port 230 of the wire management assembly 200, making the wire harness 20 around the relay neat and orderly, thereby improving the aesthetics and safety.

[0086] Furthermore, the barb 213 is provided with a first guide surface 213 a , and the protrusion 220 has a second guide surface 221 , so that the operator can insert the wire harness 20 into the wire management opening 230 with less effort.
