Technical Field

[0001] The utility model belongs to the technical field of high-voltage connectors for new energy vehicles, and specifically relates to a high-voltage connector for new energy vehicles. Background Art

[0002] New energy vehicle high-voltage connector refers to a high-voltage connector used to connect automotive batteries, motors, controllers and other components. It is an important part of the high-voltage circuit of new energy vehicles. General new energy vehicle high-voltage connectors are usually composed of contacts, insulators, shells and other accessories. They are widely used in the combined assembly of battery management systems, vehicle controllers and motor controllers of new energy vehicles.

[0003] Since new energy vehicle high-voltage connectors are mainly used in the high-voltage power distribution circuit of new energy vehicles, the working voltage is generally above 400V. At the same time, the power distribution circuit environment of new energy vehicles is relatively harsh. New energy vehicle high-voltage connectors are easily affected by factors such as humid air, dust, and vehicle vibration, resulting in unstable connections and poor contact of internal contacts.

[0004] However, the high-voltage connectors for new energy vehicles in the existing technology are mainly connected and assembled by means of bolts or snap-fits. Although this method can assemble and fix the high-voltage connectors for new energy vehicles, it cannot effectively seal and protect the high-voltage connectors for new energy vehicles, resulting in poor stability and short service life of the high-voltage connectors for new energy vehicles.

[0005] Therefore, in response to the above technical problems, it is necessary to provide a high-voltage connector for new energy vehicles.

[0006] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

[0011] In one or more embodiments of the present invention, an adsorption pad is fixedly connected to one side of the pair of Velcro strips facing away from the female Velcro strips, and the side of the adsorption pad located outside the receiving groove is flush with the outer surface of the housing. The adsorption pad adsorbs moisture from the connection between the housing and the outer sleeve.

[0012] In one or more embodiments of the present invention, the assembly plate is provided with a plurality of evenly distributed assembly through-holes. The plurality of assembly through-holes facilitates assembly and securing of the assembly plate with bolts. A snap-fit ​​groove is provided on the side of the assembly plate proximate the outer sealing ring. The outer sealing ring is assembled and secured by the engagement of the snap-fit ​​groove with the elastic assembly protrusion.

[0013] In one or more embodiments of the present invention, a resilient assembly protrusion is integrally formed on one side of the outer sealing ring close to the assembly plate, and the resilient assembly protrusion is snap-fitted into the snap-fit ​​groove. The assembly limit block is assembled and limited by the mutual cooperation between the resilient assembly protrusion and the snap-fit ​​groove.

[0014] In one or more embodiments of the present invention, an inner core block is fixedly mounted within the insulating inner housing. The inner core block secures the contact members. A pair of contact members are fixedly mounted within the inner core block. This facilitates electrical conduction between the connection terminals. A pair of connecting wires are fixedly mounted on the side of the outer sealing ring facing away from the housing. These connecting wires are in electrical communication with the contact members, transmitting electrical signals to the contact members via the pair of connecting wires.

[0015] In one or more embodiments of the present invention, the bottom seal airbag ring is hollow.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, a high-voltage connector for new energy vehicles in one embodiment of the present invention includes a housing 1 .

[0032] like Figures 1 to 2 As shown, the outer side of the housing 1 is fixedly connected with an assembly plate 2. The outer sealing ring 3 is assembled and limited by the assembly plate 2. At the same time, the housing 1 can be assembled and fixed by assembling and fixing the assembly plate 2.

[0033] Specifically, a plurality of evenly distributed assembly through holes are provided on the assembly plate 2. The plurality of assembly through holes facilitates the assembly and fixing of the assembly plate 2 with bolts.

[0034] like Figures 5 and 6 As shown, an outer sealing ring 3 is snap-fitted on one side of the assembly plate 2, so as to seal and protect the outer surface of the housing 1 by elastically deforming the outer sealing ring 3.

[0035] like Figures 5 and 6 As shown, the outer sealing ring 3 is integrally formed with an elastic assembly protrusion 12 on one side close to the assembly plate 2. The elastic assembly protrusion 12 is engaged and assembled in the engagement groove. The assembly limit block 8 is assembled and limited by the mutual cooperation between the elastic assembly protrusion 12 and the engagement groove.

[0036] Specifically, a snap-fit ​​groove is provided on one side of the assembly plate 2 close to the outer sealing ring 3. The outer sealing ring 3 is assembled and fixed by the snap-fit ​​groove and the elastic assembly protrusion 12.

[0037] like Figures 1 to 3 As shown, an insulating inner shell 4 is integrally formed in the housing 1. The inner core block 13 and the contact member 14 are assembled and fixed by the insulating inner shell 4.

[0038] like Figure 1 As shown, an inner core block 13 is fixedly assembled in the insulating inner shell 4. The contact piece 14 is assembled and fixed by the inner core block 13.

[0039] like Figure 1 As shown, a pair of contact members 14 are fixedly assembled in the inner core block 13. It is convenient to electrically conduct the connection ends through the pair of contact members 14.

[0040] like Figure 1 As shown, a pair of connecting core wires 15 are fixedly mounted on the side of the outer sealing ring 3 facing away from the housing 1 , and the pair of connecting core wires 15 are in conduction with the contact 14 . Electrical signals are transmitted to the contact 14 via the pair of connecting core wires 15 .

[0041] Specifically, a snap-fitting groove is formed between the housing 1 and the insulating inner housing 4. The snap-fitting groove is used to assemble and limit the connection terminal.

[0042] like Figures 4 to 8 As shown, a bottom sealing airbag ring 5 is sleeved on the outer side of the insulating inner shell 4. The bottom sealing airbag ring 5 is elastically deformed to seal and protect the engaging and assembling groove.

[0043] Specifically, the bottom sealing airbag ring 5 is hollow and is used to seal and protect the connection end assembled in the engaging assembly groove through the elastic deformation of the bottom sealing airbag ring 5 .

[0044] like Figure 4 As shown, a pair of side guide air cushions 6 are fixedly connected to the side of the bottom seal airbag ring 5 facing away from the assembly plate 2. These side guide air cushions 6 securely assemble and connect the bottom seal airbag ring 5 and the shock-absorbing sealing airbag ring 7, providing gas flow. Furthermore, the elastic deformation of the side guide air cushions 6 provides shock absorption protection for the connectors assembled within the mounting grooves.

[0045] The outer side of the insulating inner shell 4 is provided with a pair of assembly receiving grooves, and the pair of side guide air cushions 6 are both assembled in the assembly receiving grooves. The assembly receiving grooves are used to limit the assembly of the side guide air cushions 6.

[0046] like Figure 4 As shown, a pair of side guide air cushions 6 are integrally connected to a shock-absorbing and sealing airbag ring 7 at one end away from the bottom sealing airbag ring 5. The shock-absorbing and sealing airbag ring 7 is expanded to provide shock-absorbing and sealing protection to the connection end assembled in the engaging assembly groove.

[0047] Specifically, an annular receiving groove is defined on the side of the insulating inner shell 4 facing away from the bottom-sealing airbag ring 5. The shock-absorbing and sealing airbag ring 7 is snap-fitted into this groove. This groove limits the position of the shock-absorbing and sealing airbag ring 7 during assembly. The side of the shock-absorbing and sealing airbag ring 7 outside the groove is flush with the outer surface of the insulating inner shell 4. This minimizes interference with the assembly of the insulating inner shell 4 caused by the shock-absorbing and sealing airbag ring 7.

[0048] The shock-absorbing and sealing airbag ring 7 is hollow, and a pair of side guide air cushions 6 are provided with conductive features. The bottom sealing airbag ring 5 and the shock-absorbing and sealing airbag ring 7 are connected to each other through the pair of side guide air cushions 6. The pair of side guide air cushions 6 connect the bottom sealing airbag ring 5 and the shock-absorbing and sealing airbag ring 7, allowing the shock-absorbing and sealing airbag ring 7 to expand as the bottom sealing airbag ring 5 deforms. This expansion of the shock-absorbing and sealing airbag ring 7 can thus provide shock absorption and auxiliary sealing for the connecting end assembled in the engaging assembly groove.

[0049] like Figures 1 to 3 As shown, both sides of the housing 1 are integrally formed with assembly limit blocks 8. The assembly limit blocks 8 facilitate auxiliary assembly and positioning of the housing 1.

[0050] Specifically, a pair of receiving grooves are formed on the outer side of the housing 1 and arranged between a pair of assembly limit blocks 8. The adsorption pad 11 is assembled and received through the pair of receiving grooves.

[0051] like Figures 2 to 3As shown, a pair of magic tapes 9 are fixedly assembled in a pair of receiving grooves, and a magic tape 10 is adhered to one side of the pair of magic tapes 9. The adsorption pad 11 is conveniently assembled and fixed by the mutual adsorption of the magic tapes 9 and the magic tape 10.

[0052] like Figures 2 to 3 As shown, a pair of Velcro strips 10 are fixedly connected to an adsorption pad 11 on the side facing away from the Velcro strip 9. The side of the adsorption pad 11 located outside the receiving groove is in the same horizontal plane as the outer surface of the housing 1. The adsorption pad 11 adsorbs and protects the connection end of the housing 1 from moisture.

[0053] In specific use, before the housing 1 is plugged in and assembled, the adsorption pad 11 can be assembled into the receiving groove by adhering the female Velcro strip 9 and the secondary Velcro strip 10. Subsequently, the housing 1 can be assembled and fixed by assembling the assembly plate 2 through the multiple assembly through holes. During the assembly and fixing process, the outer sealing ring 3 can be elastically deformed to provide sealing and position protection on the outside of the housing 1.

[0054] At the same time, during the plug-in assembly process of the shell 1, the connecting end can be inserted into the snap-fit ​​assembly groove, and the bottom sealing airbag ring 5 can be squeezed by the connecting end so that the gas in the bottom sealing airbag ring 5 can be transported along the side guide air cushion 6 to the shock-absorbing sealing airbag ring 7. The expansion of the shock-absorbing sealing airbag ring 7 can assist in sealing and shock-absorbing the connecting end and the insulating inner shell 4, thereby improving the connection stability of the shell 1.

[0055] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
