[0009] Based on technical solution four, technical solution five is also provided. In technical solution five and its related embodiments, a limiting groove is provided in the second through hole, and the elastic seal is provided with a limiting portion adapted to the limiting groove so that the elastic seal and the connecting member can be limitedly connected along the extension direction of the cable.

[0010] Based on technical solution five, technical solution six is ​​also provided. In technical solution six and its related embodiments, a first slot is formed between the water retaining portion and the limiting portion, and each connector is provided with a limiting wall suitable for inserting into the first slot, and the inner surface of the limiting wall forms the slot wall of the limiting slot.

[0011] Based on technical solution six, technical solution seven is also provided. In technical solution seven and its related embodiments, the cable extends from the connecting end of the electrical module, and the outer wall where the connecting end of the electrical module is located is defined as the front wall, and each connecting head is suitable for being detachably fixed to the front wall; each connecting head is provided with a pressure wall facing the front wall; the elastic sealing member is provided with an abutting wall suitable for abutting against the outer wall of the electrical module near the front wall, and the abutting wall is clamped between the front wall and the pressure wall; the pressure wall and the abutting wall are both located in the second through hole; the surface of the pressure wall facing away from the front wall forms the groove wall of the limiting groove.

[0012] Based on Technical Solution Seven, there is also provided Technical Solution Eight. In Technical Solution Eight and its related embodiments, a flange is convexly provided in the first through hole.

[0014] Technical solution ten and its related embodiments provide an electrical module, wherein the electrical module is provided with a cable extending from a connection end, and adopts a waterproof connector for a cable as described in any one of technical solutions one to nine.

[0015] From the above description of the utility model and its preferred embodiments, it can be seen that, compared with the prior art, the technical solution of the utility model and its preferred embodiments have the following beneficial effects due to the adoption of the following technical means:

[0016] In the first technical solution, during installation, the first end and the second end of the elastic seal are moved away from each other so that the cable enters the elastic seal radially. At this time, although the elastic seal is sleeved outside the cable, it is still not tightly matched with the cable. Then, the connectors of the connector are connected to each other to form a second through hole that clamps the elastic seal radially. Under the action of the connector, the elastic seal is sealed with the cable, so that a waterproof structure can be formed on the outside of the cable. When the waterproof connector is installed on the electrical module, the waterproof and dustproof performance can be improved. During disassembly, the multiple connectors are first disassembled, and then the first end and the second end of the elastic seal are moved away from each other so that the cable can be radially separated from the elastic seal. The seal is suitable for the splicing structure of the deformation-matching connector, which makes the waterproof connector easy to disassemble and assemble. Therefore, the waterproof connector can be disassembled and assembled when both ends of the cable are connected, which is more convenient. In addition, compared with the structure where the elastic seal does not form an opening on the side, when installing the waterproof connector, it is often necessary to pass the free end of the cable through the elastic seal, and then gradually move the elastic seal along the extension direction of the cable to the connection end of the electrical module. When disassembling, the opposite is true. In order to ensure the sealing, the elastic seal and the cable are tightly matched, and the resistance during the movement is very large, so the whole operation is time-consuming and labor-intensive. The structure of the elastic seal of the present technical solution also makes the operation simpler when it is sleeved outside the cable.

[0017] In the second technical solution, the connection point of the elastic seal and the connection point of the connector are staggered along the circumferential direction, and the abutment between the first end and the second end of the elastic seal is tighter, which is more conducive to the close fit between the elastic seal and the cable.

[0018] In technical solution three, a first abutting surface is set at the first end, and a second abutting surface is set at the second end. When the elastic seal is not subjected to force, the first abutting surface and the second abutting surface abut against each other. On the one hand, the first end and the second end can be formed by directly cutting after the elastic seal is processed, which is convenient for processing; on the other hand, the cooperation of the first abutting surface and the second abutting surface makes it difficult for the elastic seal to fall off the abutment due to extrusion deformation when the elastic seal is squeezed by the connecting part. On the contrary, it fits tightly due to the tangential component of the extrusion force, thereby improving the protection effect.

[0019] In technical solution four, the elastic sealing component is provided with a water retaining portion extending out of the second through hole and abutting against the edge of the second through hole, which can increase the waterproofness at the edge of the second through hole, thereby reducing the entry of water into the second through hole and improving the protective effect.

[0020] In technical solution five, the limiting groove and the limiting portion are adapted to allow the elastic seal and the connector to be limitedly connected along the extension direction of the cable, so that the connection between the connector and the elastic seal has not only clamping force but also resistance along the extension direction of the cable, thereby making the connection more stable.

[0021] In technical solution six, a first slot is formed between the water retaining part and the limiting part, and each connector is provided with a limiting wall suitable for inserting into the first slot, and the inner surface of the limiting wall forms the slot wall of the limiting slot, which not only ensures that the water retaining part abuts against the edge of the second through hole, but also forms multiple layers of limiting between the elastic seal and the connector in the extension direction of the cable, thereby further making the connection between the connector and the elastic seal more stable.

[0022] In Technical Solution 7, the setting of the abutment wall and the pressure wall ensures the sealing of the edge of the connecting end, and further makes the connecting part and the elastic sealing part not easy to separate in the extension direction of the cable, thereby further improving the waterproof and dustproof effect of the electrical module; the surface of the pressure wall away from the front wall forms the groove wall of the limiting groove, the structure is simple and easy to process, and the pressure wall is located in the second through hole. On this basis, the abutment wall is at least partially located in the second through hole, so that the second through hole can protect the abutment wall, thereby improving the protectiveness of the edge of the abutment wall, and further providing the waterproof and dustproof effect of the electrical module.

[0023] In technical solution eight, a flange is convexly provided in the first through hole, which ensures an interference fit between the cable and the first through hole, so that even if the cable is deformed due to high pressure, it can still fit closely with the first through hole to achieve a waterproof effect.

[0024] In technical solution nine, the connecting heads are snap-connected and / or screwed to each other, and each connecting head is also provided with a connecting wall abutting against the front wall, and the connecting wall is locked on the front wall, so the structure is simple and easy to install.

[0025] In technical solution ten, the electrical module adopts the waterproof connector in the above technical solution and has the same technical advantages as the above technical solution. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] See also Figure 1-6 , Figure 1 An electrical module 10 is shown, which is provided with a cable extending from a connection end, and a waterproof connector for the cable is installed at the connection end. The outer wall where the connection end of the electrical module 10 is located is defined as the front wall 11, and the structure of the waterproof connector is described.

[0042] See also Figure 2-6 The waterproof connector includes an elastic seal 20 and a connector 30. The elastic seal 20 extends from a first end 21 to a second end 22 along the circumference of the cable. The elastic seal 20 is adapted to deform to form an opening for the cable to enter and exit radially when the first end 21 and the second end 22 are away from each other, and to form a first through hole 23 adapted to be sleeved outside the cable when the first end 21 and the second end 22 are in contact with each other. Figure 6 A flange 231 is convexly provided in the first through hole 23, and the first through hole 23 is a circular through hole. The first end 21 of the elastic seal 20 is provided with a first abutting surface (not shown in the figure) inclined relative to the radial direction of the cable, and the second end 22 of the elastic seal 20 is provided with a second abutting surface (not shown in the figure) matched with the first abutting surface. When the elastic seal 20 is not subjected to force, the first abutting surface and the second abutting surface abut each other.

[0043] See also Figure 4 The elastic seal 20 is provided with a water retaining portion 24, a limiting portion 25 and an abutting wall 26 at intervals along the extension direction of the cable, a first slot 27 is formed between the water retaining portion 24 and the limiting portion 25, and a second slot 28 is formed between the limiting portion 25 and the abutting wall 26. In this embodiment, the outer contours of the water retaining portion 24, the limiting portion 25 and the abutting wall 26 are all square, but it should be understood that in other embodiments, the outer contours of the water retaining portion 24, the limiting portion 25 and the abutting wall 26 may be elliptical or polygonal. The abutting wall 26 is suitable for abutting the front wall 11.

[0044] See also Figure 2-4 and Figure 6The connector 30 includes at least two connectors 31 arranged along the circumference of the cable, and each connector 31 is suitable for connecting and enclosing to form a second through hole 32 suitable for radially clamping the elastic seal 20 so that the elastic seal 20 and the cable fit tightly. Figure 1-6 In the embodiment, the connector 30 includes two connectors 31 arranged along the circumference of the cable. Figure 2 In the embodiment, the two connectors 31 are connected to each other. Figure 3 In the embodiment, the two connectors 31 are screwed to each other. In other embodiments, the connectors 31 can also be snap-fitted or screwed to each other at the same time, which is not limited in this embodiment. Figure 4 and Figure 6 The second through hole 32 is provided with a limiting groove 321 adapted to the limiting portion 25 so that the elastic seal 20 and the connector 30 are limitedly connected along the extension direction of the cable. Each connector 31 is provided with a limiting wall 311 suitable for inserting into the first card slot 27 and a pressing wall 312 inserted into the second card slot 28. The pressing wall 312 is close to and faces the front wall 11. The surface of the limiting wall 311 facing the front wall 11 and the surface of the pressing wall 312 away from the front wall 11 respectively form two groove walls of the limiting groove 321. The abutting wall 26 is at least partially located in the second through hole 32. The water retaining portion 24 extends out of the second through hole 32 and abuts against the edge of the second through hole 32. Figure 6 In the embodiment, the water retaining portion 24 abuts against the surface of the limiting wall 311 away from the front wall 11 and substantially blocks the hole wall of the second through hole 32. Each connector 31 is also provided with a connecting wall 313 abutting against the front wall 11, and the connecting wall 313 is locked on the front wall 11 by a stud. When the connecting wall 313 is locked with the front wall 11, the abutting wall 26 is sandwiched between the front wall 11 and the pressing wall 312.

[0045] See also Figure 2-3 The connection point of the elastic sealing member 20 is staggered with the connection point of the connecting member 30 along the circumferential direction, that is, the position of the first end 21 and the second end 22 is staggered with the connection position of the two connecting heads 31 along the circumferential direction.

[0046] The method of using the waterproof connector of this embodiment is as follows:

[0047] During installation, the first end 21 and the second end 22 of the elastic seal 20 are moved away from each other so that the cable enters the elastic seal 20 radially. At this time, although the elastic seal 20 is sleeved outside the cable, it is still not tightly fitted with the cable. Then, the connectors 31 of the connector 30 are connected to each other to form a second through hole 32 that clamps the elastic seal 20 radially. Under the action of the connector 30, the elastic seal 20 is sealed with the cable, so that a waterproof joint can be formed on the outside of the cable. When the waterproof joint is installed on the electrical module 10, the waterproof and dustproof performance can be improved. During disassembly, first disassemble the multiple connectors 31, and then move the first end 21 and the second end 22 of the elastic seal 20 away from each other so that the cable can be radially separated from the elastic seal 20.

[0048] In the present embodiment, the elastic seal 20 is suitable for the splicing structure of the deformation-matching connector 30, so that the waterproof connector can be easily assembled and disassembled, and thus the waterproof connector can be assembled and disassembled when both ends of the cable are connected, which is more convenient; in addition, compared with the structure in which the elastic seal 20 does not form an opening on the side, when installing the waterproof connector, it is often necessary to pass the free end of the cable through the elastic seal 20, and then gradually move the elastic seal 20 along the extension direction of the cable to the connection end of the electrical module 10, and in order to ensure the sealing, the elastic seal 20 and the cable are tightly matched, and the resistance during the movement is very large, so the whole operation is time-consuming and labor-intensive. The structure of the elastic seal 20 of the present technical solution also makes it easier to operate when it is sleeved outside the cable.

[0049] In this embodiment, the connection of the elastic seal 20 and the connection of the connector 30 are staggered along the circumferential direction, and the first end 21 and the second end 22 of the elastic seal 20 are more closely abutted, which is more conducive to the close fit between the elastic seal 20 and the cable.

[0050] In this embodiment, a flange 231 is protruded inside the first through hole 23 to ensure an interference fit between the cable and the first through hole 23, so that even if the cable is deformed due to high pressure, it can still fit tightly with the first through hole 23 to achieve a waterproof effect.

[0051] Furthermore, a first abutting surface is provided at the first end 21, and a second abutting surface is provided at the second end 22. When the elastic seal 20 is not subjected to force, the first abutting surface and the second abutting surface abut against each other. On the one hand, the first end 21 and the second end 22 can be formed by directly cutting after the elastic seal 20 is processed, which is convenient for processing. On the other hand, the cooperation between the first abutting surface and the second abutting surface makes it difficult for the elastic seal 20 to fall off the abutment due to extrusion deformation when the elastic seal 20 is squeezed by the connecting member 30. On the contrary, it fits tightly due to the tangential component of the extrusion force, thereby improving the protection effect.

[0052] In this embodiment, the elastic sealing member 20 is provided with a water retaining portion 24 extending out of the second through hole 32 and abutting against the edge of the second through hole 32, which can increase the waterproofness at the edge of the second through hole 32, thereby reducing the water entering the second through hole 32 and improving the protective effect.

[0053] In this embodiment, the limiting groove 321 and the limiting portion 25 are adapted to make the elastic seal 20 and the connector 30 limit connection along the extension direction of the cable, so that the connection between the connector 30 and the elastic seal 20 not only has a clamping force, but also has resistance along the extension direction of the cable, so that the connection is more stable. A first card slot 27 is formed between the water retaining portion 24 and the limiting portion, and each connector 31 is provided with a limiting wall 311 suitable for inserting into the first card slot 27. The inner surface of the limiting wall 311 forms the groove wall of the limiting groove 321, which not only ensures that the water retaining portion 24 abuts against the edge of the second through hole 32, but also forms a multi-layer limit between the elastic seal 20 and the connector 30, so as to further make the connection between the connector 30 and the elastic seal 20 more stable. The setting of the abutting wall 26 and the pressing wall 312 ensures the sealing of the edge of the connection end, thereby further improving the waterproof and dustproof effect of the electrical module 10, and further increasing the connector 30 and the elastic seal 20 are not easy to separate in the extension direction of the cable. The surface of the pressing wall 312 facing away from the front wall 11 forms a groove wall of a limiting groove 321, which has a simple structure and is easy to process, and enables the pressing wall 312 to be located in the second through hole 32. On this basis, the abutting wall 26 is at least partially located in the second through hole 32, so that the second through hole 32 can protect the abutting wall 26, thereby improving the protectiveness of the edge of the abutting wall 26, and further providing a waterproof and dustproof effect for the electrical module 10.

[0054] In this embodiment, the connectors 31 are snap-fitted and / or screw-fitted to each other. Each connector 31 is further provided with a connecting wall 313 abutting against the front wall 11. The connecting wall 313 is locked on the front wall 11, and the structure is simple and easy to install.

[0055] The description of the above specification and embodiments is used to explain the protection scope of the utility model, but does not constitute a limitation on the protection scope of the utility model. Through the enlightenment of the utility model or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent replacements or other improvements to the embodiments of the utility model or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the utility model.
