Detailed Description

In order that the utility model may be more readily understood, a more particular description of the utility model will be rendered by reference to specific embodiments that are illustrated in the appended drawings.

Referring to fig. 1 to 5, the present embodiment provides a quick-plug waterproof connector, which includes: the waterproof device comprises an outer shell 1, an insulator 2 arranged in the outer shell 1, an inner conductor 3 penetrating through the inside of the insulator 2, an outer conductor 4, a waterproof sleeve 5 and a plastic piece 7, wherein one end of the outer conductor 4 is inserted into the outer shell 1 and is welded with the inner conductor 3, the waterproof sleeve 5 is sleeved on the outer layer of a protective sleeve 8 of the outer conductor 4, and the plastic piece 7 is formed by injection molding to cover the outer layer of the waterproof sleeve 5. The waterproof sleeve 5 is completely wrapped in the plastic member 7, so that water can be prevented from penetrating from the gap between the injection molding material 7 and the protective sleeve 8 of the outer conductor 4 to cause poor electrical performance when the connector of the present embodiment is applied in a wet environment.

Specifically, the outer case 1 has a hollow inner cavity penetrating both ends thereof; an assembling cavity for interference fit connection of the insulator 2 is formed in the hollow cavity; and the insulator 2 has a hollow cavity penetrating both ends thereof; the inner conductor 3 penetrates the hollow cavity.

Secondly, a contact 6 in a ring shape is sleeved on the circumferential outer side of the end part of the insulator 2, which is far away from the outer conductor 4; and the contact 6 is in interference fit with the assembly cavity.

Furthermore, the protective sheath 8 of the outer conductor 4 is partially inserted and fixed into the outer housing 1; and the waterproof sleeve 5 comprises a main sleeve 51 sleeved on the outer layer of the protective sleeve 8 of the outer conductor 4 and an extension pipe 52 integrally connected with the main sleeve 51 and used for being sleeved on the outer layer of the part of the outer shell 1 where the protective sleeve 8 is fixed. For example, in an alternative embodiment, the waterproof sleeve 5 and the outer case 1 are both made of metallic copper.

The outer housing 1 is further provided with an elastic collar 10, which is arranged on the outer side of the end facing away from the outer conductor 4; and a first sealing ring 9 is further clamped between the outer side wall of the outer shell 1 and the inner side wall of the elastic collar 10, and the first sealing ring 9 can form a sealing fit effect between the elastic collar 10 and the outer shell 1. For the elastomeric collar 10 of the present embodiment, it may be made of metallic copper.

In more detail, referring to the drawings, an alternative embodiment is illustrated, in which the elastic collar 10 includes an annular body 101 and a plurality of notches 102 spaced apart along the circumferential direction of the annular body 101; wherein each notch 102 extends in the axial direction of the annular body 101 and each notch 102 extends to one of the axial ends of the annular body 101. The arrangement of each notch 102 on the annular body 101 is the same here. Based on this structure, that is to say, a closed loop structure is formed on the annular body 101. The notch 102 is formed by extending from one end of the annular body 101 away from the closed ring structure along the axial direction of the annular body 101. In this embodiment, the elastic collar 10 is nested on the outer side of the outer housing 1, and the design of the notch 102 on the annular body 101 is used to make the elastic collar 10 have an interference fit structure with the outer housing 1.

In addition, it should be noted that the outer side of the elastic collar 10 is also sleeved with an annular thread sleeve 11; an external thread structure 111 is formed on the outer side wall of the annular thread bush 11.

A second sealing ring 12 is also clamped between the outer side wall of the elastic lantern ring 10 and the inner side wall of the annular threaded sleeve 11; wherein the outer side wall of the annular body 101 of the elastic collar 10 is prefabricated with an annular groove 107 for embedding the second sealing ring 12. The design of the second sealing ring 12 here prevents water from penetrating into the connector from the end of the screw sleeve.

Further, the annular body 101 is provided with a raised annular barb 103 on the circumferential outer wall of the shaft end remote from the notch 102. The inner wall of the annular thread sleeve 11 is also provided with an annular concave area 112 suitable for embedding the annular barb 103; and the length of the annular recessed region 112 in the axial direction of the annular thread bush 11 is longer than the length of the annular barb 103 in the axial direction of the annular thread bush 11.

Based on the above structure, the annular thread bush 11 is in press-fit with the elastic collar 10, and is limited by means of the annular barb 103 on the elastic collar 10 after the annular thread bush 11 is pressed onto the elastic collar 10, and here, the annular recessed area 112 is longer than the annular barb 103 along the axial direction of the annular thread bush 11, so that the annular thread bush 11 can rotate around the elastic collar 10 or move back and forth, and the rapid plugging function of the connector is realized under the cooperation of the annular thread bush 11 and the elastic collar 10.

Finally, it is also necessary to say that the annular body 101 is formed with a wedge-shaped connecting portion 105 on the inner side wall of the shaft end of the notch 102; and a wedge-shaped fitting groove 113 adapted to be in plug-fit with the wedge-shaped connecting portion 105 is also formed on the inner wall of the annular threaded sleeve 11. The length of the wedge-shaped connecting portion 105 and the wedge-shaped adapting groove 113 combined with the annular concave region 112 along the axial direction of the annular thread sleeve 11 is larger than the length of the annular barb portion 103 along the axial direction of the annular thread sleeve 11, so that the annular thread sleeve 11 can move linearly back and forth relative to the elastic collar 10.
