[0038] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary, only for explaining the present application, and cannot be understood as a limitation of the present application.

[0039] As shown in Figures 1 to 6 The present embodiment provides a connector sealing structure for electrically connecting the same number of male wires 110 and female wires 310, which comprises a bridging connector 200, a sheath 400 and a sealing unit; one end of the bridging connector 200 is provided with the same number of male fixed wire grooves 201 as the male wires 110, each male wire 110 is partially installed in the corresponding male fixed wire groove 201, the male fixed wire groove 201 is filled with a male protective layer 510, the other end of the bridging connector 200 is provided with the same number of female fixed wire grooves 204 as the female wires 310, each female wire 310 is partially installed in the corresponding female fixed wire groove 204, the female fixed wire groove 204 is filled with a female protective layer 520, each male wire 110 installed in the male fixed wire groove 201 is electrically connected with the female wire 310 installed in the corresponding female fixed wire groove 204; the sheath 400 is provided with a containing cavity for containing the bridging connector 200, the containing cavity is communicated with a male through hole 402, a female through hole and a plurality of water leakage holes 401, all male wires 110 are threaded through the male through hole 402, all female wires 310 are threaded through the female through hole, the water leakage holes 401 are used for discharging the liquid in the containing cavity; the sealing unit is used for closing the female through hole.

[0040] The connector sealing structure reduces the installation difficulty of the male end wire 110 and the female end wire 310 on the bridging connector 200 by means of the openings of the male fixed wire slot 201 and the female fixed wire slot 204, ensures the stability of the installation, reduces the risk of the male end wire 110 and the female end wire 310 from being separated from the bridging connector 200 due to accidents, improves the process efficiency of the connector sealing structure, helps to reduce the setting requirement of the wire fixing jig during production, and reduces the cost of the wire fixing jig. The setting of the male end protective layer 510 and the female end protective layer 520 realizes the waterproof protection of the components in the male fixed wire slot 201 and the female fixed wire slot 204, reduces the risk of wire corrosion failure, and prolongs the service life of the connector sealing structure. The setting of the male end through hole 402 and the female end through hole realizes the position avoidance of the male end wire 110 and the female end wire 310, and also ensures the positioning ability of the male end wire 110 and the female end wire 310. The setting of the sealing unit plays a role in closing the female end through hole, reduces the risk of water entering the containing cavity, and cooperates with the opening of the water leakage hole 401 to achieve the purpose of timely discharging the liquid in the containing cavity, avoiding the accumulation of water in the containing cavity, thereby further reducing the risk of wire corrosion failure, and meeting the protection requirements of the bridging connector 200, the male end wire 110 and the female end wire 310.

[0041] In the embodiment, the bridging connector 200 is installed with an electric connection element, the number of the electric connection element is the same as that of the male end wire 110, one end of the electric connection element is placed in one male fixed wire slot 201 and electrically connected with the male end wire 110, and the other end is placed in one female fixed wire slot 204 and electrically connected with the female end wire 310. By means of the setting of the electric connection element, the design requirement that each male end wire 110 installed in the male fixed wire slot 201 is electrically connected with one female end wire 310 installed in the female fixed wire slot 204 is met. The above design is simple and reliable, has high working stability and occupies small space, and is helpful for stable operation of the connector sealing structure.

[0042] Specifically, the electric connection element is embedded in the bridging connector 200. The above design enables the electric connection element to be integrally formed with the bridging connector 200, thereby reducing the setting difficulty of the electric connection element and reducing the risk of position deviation of the electric connection element due to accidents. The above design reduces the production cost of the bridging connector 200, reduces the manufacturing difficulty of the bridging connector 200, and prolongs the service life of the bridging connector 200.

[0043] Specifically, the male end wire 110 installed in the male fixed wire slot 201 is welded on the electric connection element, and the female end wire 310 installed in the female fixed wire slot 204 is welded on the electric connection element.

[0044] In one embodiment of the present embodiment, the male fixing wire slot 201 is communicated with a male limiting through hole 202 on the side away from the female fixing wire slot 204, and the male end wire 110 passes through the male limiting through hole 202; in another embodiment of the present embodiment, the female fixing wire slot 204 is communicated with a female limiting through hole 205 on the side away from the male fixing wire slot 201, and the female end wire 310 passes through the female limiting through hole 205; in yet another embodiment of the present embodiment, the bridge connector 200 is provided with both the male limiting through hole 202 and the female limiting through hole 205.

[0045] The male limiting through hole 202 and the female limiting through hole 205 provide space for the male end wire 110 and the female end wire 310, respectively, avoiding the situation that the male end wire 110 and the female end wire 310 conflict with the bridge connector 200, and optimizing the stress condition of the male end wire 110 and the female end wire 310. Meanwhile, the layout position of the male end wire 110 and the female end wire 310 can be limited, reducing the possibility that the male end wire 110 and the female end wire 310 are separated from the male fixing wire slot 201 and the female fixing wire slot 204 due to accidents, which helps to simplify the specific structure of the connector sealing structure, reduce the occupied space, and prolong the service life.

[0046] Exemplarily, the bridge connector 200 has two opposite setting surfaces, all the male fixing wire slots 201 are recessed on the two setting surfaces, and all the female fixing wire slots 204 are recessed on the two setting surfaces. The two setting surfaces optimize the structure of the bridge connector 200, which helps to improve the layout density of the wires on the bridge connector 200, realize the lightweight improvement of the connector sealing structure, and reduce the occupied space.

[0047] Specifically, the bridge connector 200 is a cuboid. The cuboid shape has low processing difficulty and is convenient for positioning by a jig, thereby further reducing the setting requirement of the wire fixing jig, reducing the manufacturing difficulty of the connector sealing structure, and improving the process efficiency of the connector sealing structure.

[0048] In one embodiment of the present embodiment, the setting surface is provided with a male protruding plate 203, which is arranged on the side of the male fixed wire slot 201 close to the female fixed wire slot 204. In another embodiment of the present embodiment, the setting surface is provided with a female protruding plate 206, which is arranged on the side of the female fixed wire slot 204 close to the male fixed wire slot 201. In yet another embodiment of the present embodiment, the setting surface is provided with both the male protruding plate 203 and the female protruding plate 206. The arrangement of the male protruding plate 203 and the female protruding plate 206 separates the male fixed wire slot 201 and the female fixed wire slot 204, thereby reducing the probability of accidental electrical connection between the male wire 110 and the female wire 310, reducing the risk of short circuit and misconnection of the connector sealing structure, improving the safety of use, and reducing the risk of damage to external devices connected to the male wire 110 and the female wire 310.

[0049] Specifically, the male protruding plate 203 and the female protruding plate 206 abut against the inner wall of the accommodating cavity. The above arrangement avoids the accidental positional deviation of the bridge connector 200 in the accommodating cavity, ensures the stability of the arrangement of the bridge connector 200, reduces the risk of damage to the bridge connector 200, and prolongs the service life of the bridge connector 200.

[0050] In one embodiment provided by the present embodiment, the sealing unit includes a sealing block 600, which fills the female through hole. Specifically, the sealing block 600 is injection molded. The sealing block 600 ensures the sealing effect of the female through hole, reduces the risk of liquid entering the accommodating cavity from the female through hole, improves the waterproof effect of the connector sealing structure, improves the setting efficiency of the sealing unit, and avoids the relative positional deviation between the female wires 310.

[0051] As shown in Figure 7 , in another embodiment provided by the present embodiment, the sealing unit includes a protective sleeve 700, which is sleeved on the portion of the female wire 310 located in the female through hole. The design of the protective sleeve 700 sleeved on the female wire 310 reduces the setting difficulty of the sealing unit, reduces the setting cost of the sealing unit, and reduces the risk of relative positional deviation between the female wires 310.

[0052] Continuing to refer to Figures 1 to 6 , the sheath 400 is a tubular member, the male through hole 402 and the female through hole are arranged at two ends of the sheath 400, and the plurality of water leakage holes 401 are uniformly distributed on the side wall of the sheath 400. The shape of the tubular member simplifies the setting structure of the sheath 400, defines the arrangement position of the male wire 110 and the female wire 310, optimizes the layout of the connector sealing structure, and further reduces the space occupied by the connector sealing structure.

[0053] Furthermore, the accommodating cavity is divided into a receiving portion and a transition portion. The female through-hole, the receiving portion, the transition portion, and the male through-hole 402 are coaxially connected along the length of the sheath 400. The diameter of the female through-hole is larger than that of the male through-hole 402. The female through-hole and the receiving portion have the same diameter. Along the direction from the female through-hole to the male through-hole 402, the diameter of the transition portion gradually decreases until the diameter of the transition portion and the diameter of the male through-hole 402 are the same. With this design, the structure of the accommodating cavity is optimized, the processing difficulty of the accommodating cavity is reduced, and the production cost of the sheath 400 is reduced. When the bridging connector 200 needs to be placed in the accommodating cavity, it is only necessary to first pass the male wire 110 through the male through-hole 402 and then drag the male wire 110 to ensure that the male wire 110, the bridging connector 200, and the female wire 310 are all in place. This arrangement improves the process efficiency of the connector sealing structure, reduces production costs, and reduces the workload of operators.

[0054] Specifically, the water leakage hole 401 is connected to the transition portion.

[0055] In one implementation of this embodiment, the material of the male end protection layer 510 is UV glue; in another implementation of this embodiment, the material of the female end protection layer 520 is UV glue; in another implementation of this embodiment, the material of both the male end protection layer 510 and the female end protection layer 520 is UV glue.

[0056] UV glue has the advantages of strong safety and good economy. After the wire is welded to the electrical connection element, the male end protective layer 510 and the female end protective layer 520 can be formed by spraying UV glue on the surface of the solder joint after the UV glue solidifies. The above design is simple and reliable, occupies little space and has high production efficiency, ensures the waterproof effect of the connector sealing structure, and helps to achieve lightweight improvement.

[0057] like Figures 1 to 7 As shown, this embodiment also provides a wiring harness connector, including a male connector end 100, a female connector end 300 and the above-mentioned connector sealing structure, the male connector end 100 includes all male end wires 110, the female connector end 300 has the same number of female end wires 310 and each female connector end 300 includes a female end wire 310.

[0058] By means of the arrangement of the connector male end 100 and the connector female end 300, the wiring harness connector can realize the connection between components connected to multiple connector female ends 300 and a component connected to one connector male end 100, which helps to ensure the electrical connection relationship between the components.

[0059] Specifically, the connector male end 100 further comprises a male end wire sleeve 120 and a male end plug, all the male end wires 110 are connected to the male end plug at one end away from the bridging connector 200, the male end plug is used to connect external components, the male end wire sleeve 120 is of insulating material and sleeved on the outer surface of all the male end wires 110; the connector female end 300 further comprises a female end wire sleeve 320 and a female end plug 330, the female end wires 310 are connected with the female end plug 330 at one end away from the bridging connector 200, the female end plug 330 is used to connect external components, the female end wire sleeve 320 is of insulating material and sleeved on the outer surface of the female end wires 310.

[0060] The embodiment also provides a wire harness connector manufacturing process applied to the wire harness connector, comprising the following steps:

[0061] Step one: each male end wire 110 of the connector male end 100 is installed in a male fixed wire slot 201, and each female end wire 310 of the connector female end 300 is installed in a female fixed wire slot 204.

[0062] Step two: the male end protection layer 510 is used to fill the male fixed wire slot 201, and the female end protection layer 520 is used to fill the female fixed wire slot 204.

[0063] Step three: the sheath 400 is sleeved on the bridging connector 200, all the male end wires 110 pass through the male end through hole 402, and all the female end wires 310 pass through the female end through hole.

[0064] Step four: the sealing unit is used to close the female end through hole.

[0065] The wire harness connector manufacturing process achieves the assembly purpose of the wire harness connector through the above steps, and completes the assembly process of the wire harness connector. The above process is simple and direct, simplifies the process of the production process, optimizes the manufacturing process of the wire harness connector, the above steps reduce the probability of misoperation of the operator, improve the yield of the product, and help to improve the process efficiency of the wire harness connector.
