The metal sleeve is sleeved outside the thin cover, the sealing element and the thick cover to form a fixing effect. There is a limiting structure between the metal sleeve and the thick cover, and the metal sleeve is also fixed with a clamping spring, the clamping spring abuts against the rear end of the thin cover to form integral fixing.

[0003] The problem of this installation and fixing mode is that the inner wall of the metal sleeve is provided with a clamping groove, and the diameter of the clamping groove is greater than the diameter of the rear end opening of the metal sleeve, so that the installer needs to overcome the elastic force of the clamping spring to install the clamping spring into the clamping groove. In the actual operation process, manual installation is adopted at first, and long-time manual operation can easily injure the fingers of the operator, thereby affecting the processing efficiency. Then, the technical personnel in the field formulate a special fixture for the assembly of the clamping spring. Although the fixture can reduce the pressure of the hands of the operator in the actual use process, the wear rate of the fixture is relatively high (the hinge position of the fixture needs to overcome the deformation force of the clamping spring, and after wear, the clamping range of the fixture is prone to shaking, affecting assembly), and the replacement frequency of the fixture is increased, thereby increasing the production cost.

[0038] Embodiment 1

[0039] The present embodiment provides a connector convenient to install, as shown in the accompanying drawings, comprising: Figures 1-6

[0040] ​The body 11 is provided with a joint end 111, the joint end 111 includes a thin cover 12, a sealing element 13, a thick cover 14, a conductive element 15, and a metal sleeve 16 provided with a cavity 161. The thin cover 12, the sealing element 13, the thick cover 14, and the conductive element 15 are fixed to form a module. Here, the module refers to forming a whole, that is, the mutual connection and fixation between the four parts. The four parts are first installed and fixed, and then the installed whole is installed into the cavity 161, which is equivalent to that the module is accommodated in the cavity 161. In this embodiment, the thin cover 12 is connected and fixed with one side of the sealing element 13, the other side of the sealing element 13 is connected and fixed with the thick cover 14, one end of the conductive element 15 extends into the thick cover 14 through the thin cover 12 and the sealing element 13, the other end of the conductive element 15 is used to connect with a cable, and the front end of the thick cover 14 cooperates with an external connector which is inserted into the thick cover 14 to form an electrical connection with the conductive element 15.

[0041] The outer edge wall of the thick cover 14 is provided with a longitudinal groove 142 and a transverse groove 143. One end of the longitudinal groove 142 penetrates through the front end of the thick cover 14, the other end of the longitudinal groove 142 communicates with the transverse groove 143, the longitudinal groove 142 and the transverse groove 143 are perpendicular to each other, and the two form a 7-shaped structure. The inner wall of the metal sleeve 16 is provided with a first protrusion 162.

[0042] In a first state, the module is installed into the metal sleeve 16, that is, the module enters into the cavity 161 along the axial direction of the cavity 161, at this time, the first protrusion 162 slides along the longitudinal groove 142. In a second state, the module is rotated, specifically, the module is radially rotated, that is, the module rotates relative to the cavity 161, at this time, the first protrusion 162 slides along the transverse groove 143. By integrating the several parts to form a module, and then cooperating the first protrusion 162 with the longitudinal groove 142 and the transverse groove 143 to form axial locking, the connection and fixation effect between the module and the metal sleeve 16 is formed. Compared with the compression spring structure in the prior art, this structure is more convenient to install and does not need a clamp.

[0043] Specifically, as shown in the accompanying drawings, Figure 4 , Figure 6 The transverse groove 143 is provided with a limiting protrusion 1431, and the first protrusion 162 slides beyond the limiting protrusion 1431 to the end of the transverse groove 143. The limiting protrusion 1431 forms a limiting and fixing effect to prevent radial rotation. The number of limiting protrusions 1431 can be one, multiple, or symmetrically arranged. The purpose is to reduce the width of the transverse groove 143, so that when the first protrusion 162 slides beyond the limiting protrusion 1431, an elastic extrusion is formed, which is equivalent to an interference fit. After the first protrusion 162 slides beyond, a limiting and fixing effect is formed. In addition, a pin fixing mode can also be used.

[0044] Specifically, as shown in the accompanying drawings, Figures 2-3As shown, the fixed pin 17 is connected and fixed with the thick cover 14 through the metal sleeve 16, and the fixed pin 17 is embedded into the metal sleeve 16. The fixed pin 17 is connected and fixed with the thick cover 14 through the metal sleeve 16, which strengthens the fixing effect between the two, and when the fixed pin 17 is installed in place, the tail end of the fixed pin 17 does not exceed the outer edge wall of the metal sleeve 16, forming an embedded effect. In the embodiment, the number of fixed pins 17 is two, and the two fixed pins 17 are symmetrically arranged.

[0045] Specifically, as shown in the accompanying drawings Figures 2-3 As shown, the thick cover 14 is provided with a first through hole 141, and the number of first through holes 141 can be adjusted according to actual needs. In the embodiment, the number of first through holes 141 is consistent with the number of conductive parts 15. The sealing part 13 is provided with a second through hole 131, and the number of second through holes 131 is consistent with the number of conductive parts 15. The thin cover 12 is provided with a third through hole 121, and the number of third through holes 121 is consistent with the number of conductive parts 15. In the embodiment, the first through hole 141, the second through hole 131 and the third through hole 121 are coaxially arranged. The inner diameter of the second through hole 131 is smaller than that of the first through hole 141 and the third through hole 121. The second through hole 131 is provided to form an interference fit effect, so that the sealing part 13 can better realize sealing. The conductive part 15 extends into the first through hole 141 through the third through hole 121 and the second through hole 131. It should be noted that the fixed pin 17 will not extend into the first through hole 141, and the fixed pin 17 only has a fixing effect and will not be associated with the internal conductive part 15.

[0046] Specifically, as shown in the accompanying drawings Figure 5 As shown, the inner wall of the third through hole 121 is provided with a limiting part 122, and the limiting part 122 cooperates with the conductive part 15. The limiting part 122 forms a limiting effect to limit the position of the conductive part 15. The limiting part 122 and the conductive part 15 form a foolproof effect.

[0047] Specifically, the thick cover 14 is provided with a stepped protrusion 144, and the inner wall of the metal sleeve 16 is provided with a stepped groove 164 cooperating with the stepped protrusion 144. The cooperation of the stepped protrusion 144 and the stepped groove 164 prevents the thick cover 14 from protruding from the front end of the metal sleeve 16, forming a limiting and fixing effect.

[0048] Specifically, as shown in the accompanying drawings Figure 6 As shown, the edge wall of the metal sleeve 16 is also provided with a through groove 165 extending to the front end of the metal sleeve 16. The provision of the through groove 165 allows the external connector to cooperate with a certain elastic effect when the external connector is connected, thereby reducing the difficulty of plugging.

[0049] Specifically, the front end of the thick cover 14 does not exceed the front end of the metal sleeve 16.

[0050] Specifically, the thin cover 12 is fixedly connected with the sealing member 13 by splicing. The splicing between the thin cover 12 and the sealing member 13 can be the cooperation between the first positioning column and the first positioning hole, in which case the first positioning column and the first positioning hole are irrelevant to the second through hole 131 and the third through hole 121; or the splicing can be that the sealing member 13 is provided with the first positioning column, the second through hole 131 of the sealing member 13 axially penetrates the first positioning column, and the first positioning column extends into the third through hole 121 to be fixedly positioned. The sealing member 13 is fixedly connected with the thick cover 14 by splicing. The splicing between the sealing member 13 and the thick cover 14 can be the cooperation between the second positioning column and the second positioning hole, in which case the second positioning column and the second positioning hole are irrelevant to the first through hole 141 and the second through hole 131; or the splicing can be that the sealing member 13 is provided with the second positioning column, the second through hole 131 of the sealing member 13 axially penetrates the second positioning column, and the second positioning column extends into the first through hole 141 to be fixedly positioned. The splicing forms the connection and fixation between the two adjacent components. In addition, the bolt fixation or the adhesive fixation can also be used to form the connection and fixation among the three components.

[0051] Specifically, in addition to the waterproof sealing between the joint ends 111, the bent pipe of the body 11 and the connection with the cable are all waterproof designed, so as to improve the sealing level of the whole connector.

[0052] Obviously, the above embodiments are only examples for clearly illustrating but not limiting the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, all the embodiments do not need to be exhausted, and the obvious changes or variations derived therefrom are still within the protection scope of the utility model.
