[0032] The present disclosure provides a connection cable for a charging cabinet, comprising a plurality of conductive terminals and a plurality of battery core wires, each of the conductive terminals being electrically connected to a corresponding battery core wire. The connection cable for a charging cabinet further comprises:

[0033] A nylon plug, wherein the plurality of conductive terminals are arranged in the nylon plug;

[0034] A flat PVC cable body, wherein the flat PVC cable body is overmolded on the plurality of the electric core wires, and an end of the flat PVC cable body is fixedly connected to the nylon plug;

[0035] A PVC plastic sleeve is overmolded on the end of the flat PVC cable body and extends to the end surface of the nylon plug.

[0036] See also Figures 1 to 5 In order to better understand the connection cable 10 for the charging cabinet of the present disclosure, the connection cable 10 for the charging cabinet is further explained below:

[0037] A connection cable 10 for a charging cabinet in one embodiment includes a plurality of conductive terminals 100 and a plurality of electric core wires 200, and each of the conductive terminals 100 is electrically connected to the corresponding electric core wire 200. The connection cable 10 for a charging cabinet also includes a nylon plug 300, a flat PVC cable body 400, and a PVC plastic sleeve 500. The plurality of conductive terminals 100 are arranged in the nylon plug 300. The flat PVC cable body 400 is overmolded on the plurality of electric core wires 200, and the end of the flat PVC cable body 400 is fixedly connected to the nylon plug 300. The PVC plastic sleeve 500 is overmolded on the end of the flat PVC cable body 400, and the PVC plastic sleeve 500 extends to the end surface of the nylon plug 300.

[0038] In this embodiment, the outer contour of the flat PVC cable body 400 is set to a flat shape, so that the flat PVC cable body 400 can be used for wiring in a relatively small space in a multi-battery module charging cabinet, thereby making it easier to use multiple battery modules in series. The PVC plastic sleeve 500 is overmolded on the end of the flat PVC cable body 400, and the PVC plastic sleeve 500 extends to the end surface of the nylon plug 300. At the same time, the PVC plastic sleeve 500 uses the same PVC material as the flat PVC cable body 400, so that it can not only improve the adhesion of the PVC plastic sleeve 500 overmolded on the flat PVC cable body 400, but also effectively avoid the problem of easy breakage at the connection when the end of the flat PVC cable body 400 and the nylon plug 300 are bent. This effectively improves the convenience of use of the connecting cable 10 for the charging cabinet in scenarios where space is limited.

[0039] like Figures 2 to 4 As shown, in one embodiment, each of the electrical core wires 200 is arranged in parallel, and the multiple conductive terminals 100 are respectively m power conductive terminals 110 and n signal conductive terminals 120, wherein m and n are both positive integers; the multiple electrical core wires 200 include m power core wires 210 and n signal core wires 220, the m power core wires 210 are electrically connected to the m power conductive terminals 110 in a one-to-one correspondence, and the n signal core wires 220 are electrically connected to the n signal conductive terminals 120 in a one-to-one correspondence.

[0040] It can be understood that the battery core wires 200 are arranged in parallel in an orderly manner without interfering with each other, thereby improving the convenience of assembly when the m power core wires 210 are electrically connected to the m power conductive terminals 110 in a one-to-one correspondence and the n signal core wires 220 are electrically connected to the n signal conductive terminals 120 in a one-to-one correspondence, and effectively avoiding the situation in which the difficulty of assembly is increased due to the tangled connection of the joints of the battery core wires 200.

[0041] like Figure 3 and Figure 4 As shown, in one embodiment, the number of the nylon plugs 300 is two, and the two nylon plugs 300 are connected to the two ends of the flat PVC cable body 400. In one embodiment, the end of the nylon plug 300 away from the flat PVC cable body 400 is provided with a plug slot 301, and the plug end of each conductive terminal 100 is exposed in the plug slot 301, and the cross section of the flat PVC cable body 400 is rectangular or elliptical. It can be understood that the nylon plugs 300 at both ends of the connecting cable 10 for the charging cabinet can be respectively plugged into the power socket of one battery module and the power socket of another battery module through the plug end of the conductive terminal 100, so as to realize the series connection of multiple battery modules. Since the cross section of the flat PVC cable body 400 is rectangular or elliptical, the bending effect of the flat PVC cable body 400 can be improved, which is conducive to the arrangement of cables in the relatively narrow space in the charging cabinet.

[0042] like Figure 3 As shown, in one embodiment, the two side walls of the nylon plug 300 are respectively formed with a first air-avoiding hole 302 and a second air-avoiding hole 303. In one embodiment, the nylon plug 300 further includes an integrally formed first plug-in guide through hole 304 and a second plug-in guide through hole 305, and the first plug-in guide through hole 304 and the second plug-in guide through hole 305 are diagonally arranged away from the end of the flat PVC cable body 400.

[0043] It can be understood that in this embodiment, when the nylon plug 300 is plugged into the power socket of the battery module, the first plug-in guide through hole 304 and the second plug-in guide through hole 305 are aligned with the corresponding guide posts in the power socket of the battery module respectively, and then the nylon plug 300 is plugged into the power socket of the battery module so that the plug-in end of the conductive terminal 100 can be fully aligned and connected with the power socket of the battery module; finally, a screw is used to connect the threaded hole of the first plug-in guide through hole 304 and the power socket of the battery module, and similarly, another screw is used to connect the threaded hole of the second plug-in guide through hole 305 and the power socket of the battery module, thereby effectively improving the connection stability between the nylon plug 300 and the power socket of the battery module. At the same time, it can also ensure that when the flat PVC cable body 400 is bent and twisted, the nylon plug 300 will not fall off from the power socket of the battery module.

[0044] like Figure 3 and Figure 5As shown, in one embodiment, the outer wall of the PVC plastic sleeve 500 is respectively formed with a first anti-slip portion 510 and a second anti-slip portion 520, the first anti-slip portion 510 and the second anti-slip portion 520 are respectively located on the opposite side walls of the PVC plastic sleeve 500, the first anti-slip portion 510 is respectively staggered at the first air avoidance hole 302 and the second air avoidance hole 303, and the second anti-slip portion 520 is respectively staggered at the first air avoidance hole 302 and the second air avoidance hole 303. It can be understood that the user can increase the grip of the PVC plastic sleeve 500 by holding the first anti-slip portion 510 and the second anti-slip portion 520, so as to facilitate the user to plug or unplug the nylon plug 300 and the power socket of the battery module.

[0045] like Figure 2 As shown, in one embodiment, the connection cable 10 for the charging cabinet further includes a soft rubber handle 600, and both ends of the soft rubber handle 600 are connected to the PVC plastic sleeve 500. In one embodiment, both ends of the soft rubber handle 600 are movably connected to the PVC plastic sleeve 500. In one embodiment, both ends of the soft rubber handle 600 are rotatably connected to the PVC plastic sleeve 500. It can be understood that the soft rubber handle 600 can improve the convenience of storing the connection cable 10 for the charging cabinet. Specifically, the user can move and place the connection cable 10 for the charging cabinet by holding the soft rubber handle 600, or hang the idle connection cable 10 for the charging cabinet high on the wall, which is conducive to ventilation and drying, and can prevent the conductive terminal 100 in the nylon plug 300 from being affected by moisture. In this embodiment, both ends of the soft rubber handle 600 are sleeved on a rotating plastic screw or a rotating metal screw, and the rotating plastic screw or the rotating metal screw is movably buckled with the PVC plastic sleeve 500, so that both ends of the soft rubber handle 600 are rotatably connected to the PVC plastic sleeve 500.

[0046] Compared with the prior art, the present invention has at least the following advantages:

[0047] The outer contour of the flat PVC cable body is set to a flat shape, so that the flat PVC cable body can be used for wiring in a relatively small space in a multi-battery module charging cabinet, making it easier to use multiple battery modules in series. The PVC plastic sleeve is overmolded on the end of the flat PVC cable body, and the PVC plastic sleeve extends to the end face of the nylon plug. At the same time, the PVC plastic sleeve uses the same PVC material as the flat PVC cable body, which not only improves the adhesion of the PVC plastic sleeve overmolded on the flat PVC cable body, but also effectively avoids the problem of easy breakage at the connection when the end of the flat PVC cable body and the nylon plug are bent. This effectively improves the ease of use of the connecting cable for the charging cabinet in scenarios where space is restricted.

[0048] The above-mentioned embodiments only express several implementation methods of the present disclosure, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the disclosed patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present disclosure, and these all belong to the protection scope of the present disclosure.
