As shown in fig. 2 and 3, the workpiece 20 has a housing structure, and the workpiece 20 is provided with a mounting hole 200, and the mounting hole 200 communicates an inner side 210 and an outer side 220 of the workpiece 20. The mounting hole 200 includes an outer opening 201 and an inner opening 202, and an inner wall 203 of the mounting hole 200 extends from the outer opening 201 to the inner opening 202. The connector 10 is elongated and includes a first end 110 and a second end 120, the connector 10 includes a housing and a conductive member disposed in the housing, the conductive member extends along the elongated connector 10, that is, extends from the first end 110 to the second end 120, the component inside the workpiece 20 is electrically connected to the conductive member at the second end 120 of the connector 10, the component outside the workpiece 20 is electrically connected to the conductive member at the second end 120 of the connector 10, and thus, the electrical connection between the component inside the workpiece 20 and the component outside is realized through the connector 10, and functions of power supply or signal interaction between the component inside the workpiece 20 and the component outside can be realized. And the connector 10 is connected with the workpiece 20 in a sealing manner, so that the waterproof and dustproof effects are achieved, water vapor outside the workpiece 20 cannot enter the workpiece 20, and the stability of parts inside the workpiece 20 is ensured.

As shown in fig. 1, the connector 10 is elongated, the connector 10 is inserted into the mounting hole 200 along the length direction, the second end 120 of the connector 10 protrudes outward along the direction perpendicular to the length direction of the connector 10 to form an abutment wall 120A, as shown in fig. 2 and 3, the connector 10 is mounted from the inner side 210 to the outer side 220 of the workpiece 20, that is, after the first end 110 of the connector 10 is inserted into the mounting hole 200 from the inner opening 202 of the mounting hole 200 of the workpiece 20 and protrudes from the outer opening 201, and the abutment wall 120A of the second end 120 of the connector 10 abuts against the end of the inner opening 202 of the mounting hole 200 after the first end 110 of the connector 10 protrudes from the outer opening 201 of the mounting hole 200 to form a sealing structure. The first end 110 of the connector 10 protrudes from the outer opening 201 of the mounting hole 200 to facilitate electrical connection with external components. A direction in which the inner opening 202 of the mounting hole 200 of the workpiece 20 is directed toward the outer opening 201 is defined as a first direction, that is, the connector 10 is inserted into the mounting hole 200 from the inner side 210 of the workpiece 20 in the first direction. Further, the connector 10 is provided with the elastic locking piece 130, the workpiece 20 is provided with the locking groove 230, and after the connector 10 is inserted into the mounting hole 200 from the inner side 210 of the workpiece 20 along the first direction, when the abutting wall 120A of the second end 120 of the connector 10 abuts against the end of the inner opening 202 of the mounting hole 200, the elastic locking piece 130 is locked with the locking groove 230, that is, the elastic locking piece 130 is locked with the locking groove 230 so as to limit the connector 10 from exiting the mounting hole 200 of the workpiece 20 along the direction opposite to the first direction. In some embodiments, the abutting wall 120A of the second end 120 of the connector 10 is a thin-walled structure and has a certain elasticity, when the connector 10 is inserted into the installation hole 200 along the first direction and the elastic abutting wall 120A of the connector 10 just abuts against the end of the inner opening 202 of the installation hole 200, the elastic locking element 130 is not locked with the locking groove 230, and the abutting wall 120A of the connector 10 is further pushed to abut against the end of the inner opening 202 of the installation hole 200 along the first direction so that the elastic locking element 130 is locked with the locking groove 230 after the abutting wall 120A is elastically deformed. At this time, the abutting wall 120A is merely abutted against the end of the opening 202 in the mounting hole 200 by the elastic force, which greatly increases the waterproofness.

In the above embodiment, as shown in fig. 3, the abutting wall 120A of the second end 120 of the connector 10 abuts on the end of the inner opening 202 of the mounting hole 200 to form the sealing portion a, which is disposed at the innermost side 210 where the connector 10 abuts against the workpiece 20, and since the innermost side 210 generally has less water, the reliability of water resistance is greatly improved. It is easily conceived that if the seal a is provided at the outer side 220 of the mounting hole 200 or at the middle of the mounting hole 200, the seal a in both cases has a greater chance of being exposed to a place where water is much, and is less waterproof than if the seal a is provided at the innermost side 210 of the mounting hole 200.

In one embodiment, the elastic locking member 130 is in a hook shape, and the elastic locking member 130 may be made of a plastic material or may be made of a metal material. Elastic locking piece 130 one end is connected in connector 10, and the other end forms the interval with connector 10, and when pressing elastic locking piece 130 towards the direction of connector 10 shell, elastic deformation can take place for elastic locking piece 130, and after removing external force, the free end of elastic locking piece 130 can move towards the direction of keeping away from the connector 10 shell under the effect of elastic restoring force. As shown in fig. 2, the locking groove 230 is disposed in the mounting hole 200 near the outer opening 201.

As shown in fig. 2, the inner side 210 of the workpiece 20 is provided with a guide slope 240, the guide slope 240 is disposed at the outer side 220 of the inner opening 202 of the mounting hole 200, and one end of the guide slope 240 is connected to the inner opening 202. When the connector 10 is inserted into the mounting hole 200 in the first direction, the free end of the elastic locking piece 130 is gradually elastically compressed and deformed by the interference of the guide slope 240, and the elastic locking piece 130 is gradually inserted into the mounting hole 200 by the guide of the guide slope 240.

In one embodiment, as shown in fig. 1, the connector 10 is provided with a water-locking ring 140 between the first end 110 and the second end 120, the water-locking ring 140 protruding around the circumference of the connector 10, and as shown in fig. 2, when the connector 10 is inserted into the mounting hole 200 in the first direction, the water-locking ring 140 can abut against the inner wall 203 of the mounting hole 200. In some embodiments, a plurality of water-lock rings 140 are disposed along the length of the connector 10, as shown in fig. 1, four water-lock rings 140 are disposed along the length of the connector 10, and the water-lock rings 140 are disposed between the first end 110 and the second end 120. As shown in fig. 3, when the elastic locking member 130 is locked with the locking groove 230, at least one water locking ring 140 is disposed at the inner opening 202 of the mounting hole 200 and forms a seal at the inner opening 202, and the elastic locking member 130 is disposed between the two water locking rings 140 to increase water locking. As shown in fig. 3, the special structure of the elastic locking piece 130 and the locking groove 230 causes the connector 10 to have a weak water locking capability at the position of the elastic locking piece 130 and the locking groove 230, and the water locking rings 140 are provided at both the front and rear of the elastic locking piece 130, thereby improving the water locking capability.

In one embodiment, as shown in fig. 1, in which a groove 150 is formed between two water-locking rings 140, in conjunction with fig. 2 or fig. 3, a flexible annular water-locking member 160 is disposed in the groove 150, and the annular water-locking member 160 may be made of a rubber material. Naturally, the outermost periphery of the annular water-locking member 160 protrudes from the outermost periphery of the water-locking ring 140, so that the annular water-locking member 160 can firmly and elastically abut against the inner wall 203 of the mounting hole 200 to form a seal.

In one embodiment, the annular water lock 160 is disposed proximate the second end 120 of the connector 10.
