For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The utility model discloses a connector, such as Figure 1 , 2 As shown, the connector includes a shielding component, a housing component 2, a lock cylinder 3, and a waterproof fixing component.

[0026] The shielding assembly includes a contact, an insulating member, a shielding body and other structures. The insulating member is placed between the contact and the shielding body. The connection structure of the three is prior art and will not be described in detail here. Figure 3 As shown, the shielding assembly includes a square plug-in end 11 and a circular locking end 12. Correspondingly, the plug-in ends of the insulating member and the shielding body are both oriented in the same direction, and the contact member can still adopt any existing structure. A locking groove 13 is provided on the shielding assembly, and a shielding spring sheet 14 is provided on the plug-in end 11, that is, a shielding spring sheet 14 is provided on the shielding body. The locking groove 13 is provided on the shielding body.

[0027] The housing component is provided with a receiving through hole for receiving the shielding component. The receiving through hole is provided with an elastic locking member 21 whose one end can be inserted into the locking groove 13 .

[0028] One end of the lock cylinder is inserted into the gap between the elastic locking member 21 and the side wall of the accommodating through hole;

[0029] The waterproof fixing assembly includes a first waterproof fixing structure disposed at the plug-in end 11 and fixed on the housing assembly, and a second waterproof fixing structure disposed at the locking end 12 and fixed on the housing assembly.

[0030] With the above structure, the elastic locking member 21 is placed in the locking groove 13 to achieve the first locking. Due to the elasticity of the elastic locking member 21, when the pulling force is greater than the threshold, it will deform and will be separated from the locking groove 13. In this regard, a lock cylinder is inserted into the gap between the elastic locking member 21 and the side wall of the accommodating through hole to achieve secondary locking, thereby preventing the elastic locking member 21 from being separated from the locking groove 13. The structure has high stability. The mating end of the shielding component is square, which increases the design area of ​​the shielding spring sheet, increases the area in the width direction, and improves the contact reliability of the connector in a vibration environment. Waterproof fixing components are set at both ends to achieve waterproofing, further improving the waterproof performance of the connector.

[0031] In order to further enhance the shielding conduction performance and the shielding reliability, shielding spring pieces 14 are arranged on the four side surfaces of the plug end 11 .

[0032] In order to improve the perception of insertion into place, a first step structure 31 abutting against the elastic locking piece 21 is provided on the lock cylinder 3 and a stop protrusion 32 is provided on the outer wall of the other end of the lock cylinder; a second step structure 22 abutting against the stop protrusion 32 is provided in the accommodating through hole.

[0033] The waterproof fixing assembly can be implemented in a variety of structures, for example, Figure 2 As shown, the first waterproof fixing structure includes a first end cover 411 fixed to the housing component 2 and a first sealing ring 412 sleeved at the connection between the housing component 2 and the first end cover 411. The second waterproof fixing structure includes a second end cover 422 fixed to the housing component 2 and a second waterproof ring 421 placed between the lock cylinder 3 and the second end cover.

[0034] The elastic locking member 21 can adopt the solution in the prior art, that is, a bent portion structure, or can be Figure 2 As described above, a clamping protrusion is arranged on the spring sheet to form an elastic locking member.

[0035] The lock cylinder 3 can be implemented in a variety of structures, such as a straight cylinder. In order to facilitate installation and improve the stability of the lock cylinder 3, such as Figure 4 As shown, at least one groove structure 33 is provided at one end of the lock cylinder 3. The diameter of the lock cylinder 3 gradually decreases from one end to the other end, that is, the diameter of the lock cylinder 3 gradually decreases from the end provided with the groove structure 33 to the end provided with the second step structure 22, and the diameter here is the outer diameter.

[0036] In order to make the lock cylinder deform better during the plugging process, at least two groove structures are provided.

[0037] To facilitate installation, the width of the groove structure in the circumferential direction of the locking end 12 is smaller than the width of the elastic locking member.

[0038] The diameter of the smaller end of the lock cylinder is less than or equal to the diameter of the receiving hole, and the diameter of the larger end is slightly larger than the diameter of the receiving hole. With the above structure, after the lock cylinder is placed in the receiving hole, one end of the groove structure 33 is deformed and fits with the inner wall of the receiving hole, so that the position can remain unchanged in a vibration environment.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
