[0035] Embodiment 1

[0036] Please refer to Figures 1 to 7 The utility model proposes a male end component 10, which is applied to a plug-in connector 100. The plug-in connector 100 includes a female end component 20, and the male end component 10 includes: a male end body 11, and the male end body 11 is provided with an insertion cavity 111 and a first accommodating cavity 112; a male end contact 12, at least two of the male end contacts 12 are arranged in the insertion cavity 111; and a short-circuit spring 13, each of the male end contacts 12 is connected to at least one short-circuit spring 13, and at least a first short-circuit portion 131 and a second short-circuit portion 132 are provided on the short-circuit spring 13, and the first short-circuit portion 131 and the second short-circuit portion 132 are arranged in the first accommodating cavity 112; wherein the male end component 10 has a first state of contact and conduction with the female end component 20 and a second state of disconnection from the female end component 20.

[0037] In the above-mentioned embodiment of the present application, the male end assembly 10 includes a male end body 11, a male end contact 12 and a short-circuit spring 13. The first accommodating cavity 112 on the male end body 11 is used to accommodate the short-circuit spring 13, and the male end contact 12 is arranged in the plug-in cavity 111 of the male end body 11; the short-circuit spring 13 is connected to the male end contact 12, and a first short-circuit portion 131 and a second short-circuit portion 132 are arranged on the short-circuit spring 13. When two adjacent first short-circuit portions 131 are in contact, and two adjacent second short-circuit portions 132 are in contact at the same time, the corresponding male end contact 12 connected by the short-circuit spring 13 can realize a double short-circuit function to improve the short-circuit reliability, thereby significantly improving the safety of use of the operator; when two adjacent first short-circuit portions 131 are in contact, or two adjacent second short-circuit portions 132 are in contact, the corresponding male end contact 12 connected by the short-circuit spring 13 can also realize a short-circuit function.

[0038] The number of short-circuit springs 13 can be set according to actual needs, and can be two, four, or more; accordingly, each male contact 12 can be connected to two short-circuit springs 13, or multiple short-circuit springs 13, thereby forming multiple short-circuit functions according to actual needs, making the short-circuit function more reliable.

[0039] The male end component 10 has a first state in which it is in contact and connected with the female end component 20 and a second state in which it is disconnected from the female end component 20. In the first state, the male end component 10 is in contact and connected with the female end component 20, at which time, the two adjacent first short-circuit parts 131 and the two adjacent second short-circuit parts 132 are disconnected; in the second state, the male end component 10 is disconnected from the female end component 20, at which time the two adjacent first short-circuit parts 131 in the male end component 10 are in contact with each other and the two adjacent second short-circuit parts 132 are in contact with each other, so that the corresponding two male end contact members 12 are short-circuited.

[0040] The two first short-circuit parts 131 and the two adjacent second short-circuit parts 132 of the adjacent short-circuit springs 13 can respectively contact each other to achieve double self-short-circuit, forming a double insurance short-circuit function, one to ensure that the short-circuit can be achieved, and the other to ensure that the short-circuit function can be achieved in the male terminal assembly 10.

[0041] By providing the first short-circuit portion 131 and the second short-circuit portion 132 on the short-circuit spring 13, a double-safety short-circuit is achieved, which can improve contact stability, reduce the risk of electric shock, increase the service life of the connector 100, and improve safety performance.

[0042] The technical solution of the utility model is to set two short-circuit parts on the short-circuit spring 13, and the two adjacent short-circuit springs 13 are in contact with each other through the two first short-circuit parts 131 and the two second short-circuit parts 132, so that the corresponding two male contact pieces 12 are in a short-circuit state, thereby achieving the short-circuit function and the withstand voltage requirement. By setting the first short-circuit part 131 and the second short-circuit part 132 at the same time, a double connection can be achieved, making the self-short-circuit function more reliable. Even if one of the short-circuit springs 13 fails to self-short after a long period of working, the other self-short can still work normally, which can ensure the normal self-short-circuit function, ensure the personal safety of the operator, and enhance the safety and reliability of the use of the equipment.

[0043] In an embodiment of the present utility model, the short-circuit spring 13 has a fixed end 133 and a spring end 134, the fixed end 133 is fixed on the male contact 12, and the spring end 134 extends toward the first accommodating cavity 112; the first short-circuit portion 131 and the second short-circuit portion 132 are sequentially arranged on the spring end 134.

[0044] In detail, the fixed end 133 of the shorting spring 13 is used to be fixed on the male contact 12 and maintain contact and conduction with the male contact 12; the fixed end 133 and the male contact 12 can be integrally connected or separately fixedly connected in various forms. The spring end 134 of the shorting spring 13 extends toward the first accommodating cavity 112, so that two adjacent shorting springs 13 form mutual contact in the first accommodating cavity 112.

[0045] In one embodiment, if Figure 7 The fixed end 133 of the short-circuit spring 13 is sleeved on the outside of the male contact 12, and the spring end 134 of the short-circuit spring 13 extends toward the first accommodating cavity 112. The first short-circuit portion 131 and the second short-circuit portion 132 are sequentially arranged on the spring end 134 so as to achieve contact and conduction in the first accommodating cavity 112.

[0046] In the embodiment of the present invention, the first short-circuit portion 131 is formed by the head of the spring end 134 extending and bending toward the center axis of the first accommodating cavity 112 ; the two opposite first short-circuit portions 131 are in contact and conduction at the center axis of the first accommodating cavity 112 .

[0047] It is worth noting that the shape and contact method of the first short-circuit portion 131 and the second short-circuit portion 132 can be set according to actual needs. They can be bent to form a raised contact point, and the two contact points are in stable contact; they can also be set in a plate shape to form a raised contact surface, and the two contact surfaces are in contact; they can also be connected to the two short-circuit portions by setting an intermediate connecting piece.

[0048] like Figure 3 In one embodiment, the first short-circuit portion 131 and the second short-circuit portion 132 are arranged in sequence from top to bottom along the height direction of the spring end 134. The first short-circuit portion 131 is arranged close to the head of the spring end 134, and the second short-circuit portion 132 is arranged close to the fixed end 133. The head of the spring end 134 is the end of the spring end 134 away from the fixed end 133. The first short-circuit portion 131 extends from the head of the spring end 134 toward the central axis of the first accommodating cavity 112 and is bent. The two first short-circuit portions 131 are bent to form a convex contact point, and contact is conducted through the two contact points. The two first short-circuit portions 131 contact each other through their own elastic influence to achieve a self-short circuit function.

[0049] In an embodiment of the utility model, the second short-circuit portion 132 is formed by punching and bending the main body of the spring end 134 toward the central axis of the first accommodating cavity 112; the male end assembly 10 also includes a movable short-circuit component 14, which is arranged in the first accommodating cavity 112 and displaced along the central axis of the first accommodating cavity 112, and the two opposite second short-circuit portions 132 are respectively abutted against the movable short-circuit component 14 to achieve contact and conduction.

[0050] Specifically, the main body of the spring end 134 refers to the middle part of the spring end 134. Figure 7 The second short-circuit portion 132 is formed by accurately cutting the main body of the spring end 134 through a stamping tool. The second short-circuit portion 132 is also bent toward the central axis of the first accommodating cavity 112 so that two adjacent second short-circuit portions 132 are located in the first accommodating cavity 112.

[0051] The movable short-circuit 14 is movably connected to the male end body 11 and can be displaced along the central axis of the first accommodating cavity 112. The two adjacent second short-circuit parts 132 are in contact with each other by abutting against the movable short-circuit 14. This method can reduce the wear of the two adjacent second short-circuit parts 132 in direct contact and improve the reliability of short-circuit. The movable short-circuit 14 can be a movable metal contact rod or a movable metal contact sheet. Its specific structure can be set according to actual needs, as long as it can form contact with the two second short-circuit parts 132.

[0052] At the same time, this contact mode is distinguished from the contact mode of two adjacent first short-circuit parts 131, which can avoid the two same modes from forming relatively consistent wear after long-term use, avoid the situation where two self-short circuits fail at the same time, and improve the reliability of the equipment.

[0053] In an embodiment of the utility model, the movable short-circuit 14 includes a positioning column 141, a metal short-circuit sheet 142 and an elastic element 143. The first end 1411 of the positioning column 141 can be movably arranged at the bottom of the first accommodating cavity 112. The metal short-circuit sheet 142 is fixedly clamped to the first end 1411 of the positioning column 141. The compression deformation of the elastic element 143 is linearly related to the movable stroke of the positioning column 141. The two opposite second short-circuit portions 132 are respectively abutted against the metal short-circuit sheet 142 to achieve contact conduction.

[0054] In detail, the first end 1411 of the positioning column 141 refers to the end of the positioning column 141 close to the short-circuit spring 13. The positioning column 141 can be movably arranged at the bottom of the first accommodating cavity 112 to drive the metal short-circuit sheet 142 to move. The compression deformation of the elastic element 143 is linearly related to the movable stroke of the positioning column 141. The elastic element 143 can be arranged in the first accommodating cavity 112 and abutted between the positioning column 141 and the male end body 11. A mounting groove can also be provided to fix the elastic element 143 and connect the elastic element to the positioning column 141. The mounting method can be set according to actual conditions, and it is only necessary to enable the elastic element 143 to reset the positioning column 141 after the movement. The two adjacent second short-circuit portions 132 are respectively abutted on the metal short-circuit sheet 142 to achieve contact conduction, that is, they contact each other through the metal short-circuit sheet 142 as a bridge to achieve the self-short-circuit function.

[0055] In an embodiment of the utility model, a positioning hole 113 is formed at the bottom of the first accommodating cavity 112, and the second end 1412 of the positioning column 141 is movably disposed in the positioning hole 113. A positioning step 1131 is convexly formed on the hole wall of the positioning hole 113, and a supporting step 1413 is convexly formed on the outer wall of the second end 1412 of the positioning column 141. The supporting step 1413 abuts against the positioning step 1131 to limit the maximum movable stroke of the positioning column 141 when the elastic element 143 is reset; one end of the elastic element 143 abuts against the second end 1412 of the positioning column 141, and the other end of the elastic element 143 abuts against the male end body 11.

[0056] It is worth noting that a positioning hole 113 is provided at the bottom of the male end body 11 located in the first accommodating cavity 112, and the second end portion 1412 of the positioning column 141 refers to the end of the positioning column 141 away from the short-circuit spring piece 13, and the second end portion 1412 of the positioning column 141 is arranged in the positioning hole 113, and the movement of the positioning column 141 is guided by the positioning hole 113, and the positioning column 141 is limited by the positioning step 1131 and the supporting step 1413 to ensure that the positioning column 141 can move stably in the positioning hole 113, accurately realize the contact and conduction between the metal short-circuit sheet 142 and the two adjacent second short-circuit parts 132 in the first state, and disconnect the metal short-circuit sheet 142 from the two adjacent second short-circuit parts 132 in the first state.

[0057] The elastic element 143 is disposed in the positioning hole 113 and abuts between the positioning column 141 and the male end body 11 . The elastic element 143 can be a spring or an elastic airbag. The elastic element 143 can reset the movement of the positioning column 141 .

[0058] In an embodiment of the utility model, the male end body 11 is further provided with a second accommodating cavity 114, the second accommodating cavity 114 is connected with the first accommodating cavity 112 through the positioning hole 113, and the central axis of the first accommodating cavity 112, the central axis of the positioning hole 113 and the central axis of the second accommodating cavity 114 coincide with each other; and the elastic element 143 is arranged in the second accommodating cavity 114, the second end 1412 of the positioning column 141 is provided with a first abutting groove, and the male end body 11 is provided with a second abutting groove; one end of the elastic element 143 abuts against the first abutting groove, and the other end of the elastic element 143 abuts against the second abutting groove.

[0059] In detail, the second accommodating cavity 114 is connected to the positioning hole 113 and the first accommodating cavity 112. The second accommodating cavity 114 is used to install the elastic element 143 and can guide the movement of the elastic element 143. The two ends of the elastic element 143 are respectively abutted in the first abutting groove and the second abutting groove to maintain the stability of the connection of the elastic element 143. Figure 3 When the elastic element 143 is in a natural state, the elastic element 143 enables the positioning column 141 to have a tendency to keep the metal shorting piece 142 in contact with the second shorting portion 132 .

[0060] In the embodiment of the utility model, the first end 1411 of the positioning column 141 is provided with an escape groove 1414 so that the first end 1411 of the positioning column 141 forms two opposite abutment columns 1415 ; the metal shorting piece 142 is fixedly clamped at the bottom of the escape groove 1414 .

[0061] Specifically, Figure 5 A avoidance groove 1414 is opened at the first end portion 1411 of the positioning column 141 to form two opposite abutting columns 1415 at the first end portion 1411 of the positioning column 141. The metal shorting piece 142 is arranged at the bottom of the avoidance groove 1414.

At the same time, the plug-in contact piece 32 is inserted into the male contact piece 12 and the female contact piece 22, and the male end component 10 is conductive with the female end component 20.

[0077] In the second state, the insulating isolation piece 311 is separated from the first accommodating cavity 112, so that the two short-circuiting spring pieces 13 can contact and conduct, so that the corresponding two male contact pieces 12 are short-circuited.
