Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0025] See also Figure 1-7 The present invention provides a technical solution: a double-head quick-plug push-pull self-locking connector, including a rubber core component 100, a rubber core component support mechanism 200, a rubber core fixing mechanism 300, a second plug shell 400, a third plug shell 500 and a positioning adapter 600.

[0026] The rubber core assembly 100 includes a first rubber core body 110 and a second rubber core body 120, and the first rubber core body 110 and the second rubber core body 120 are fixedly plugged with a plurality of plug pins 130 arranged in a certain order, and the two groups of plug pins 130 are connected and conducted by a stretchable wire 140; the rubber core assembly support mechanism 200 includes a first insulating support sheet 210 and a second insulating support sheet 220, and the first insulating support sheet 210 and the second insulating support sheet 220 are sleeved on the outside of the first rubber core body 110 and the second rubber core body 120 through a positioning mechanism 230; the rubber core fixing mechanism 300 is respectively installed on the first rubber core body 110 and the outside of the second rubber core body 120; and the first rubber core body 110 and the second rubber core body 120 are respectively covered with a plug inner shell 330 and a first plug outer shell 340 through a rubber core fixing mechanism 300, and an external thread 331 is provided on the outside of the plug inner shell 330; the second plug outer shell 400 is sleeved on the outside of the plug inner shell 330, the third plug outer shell 500 is sleeved on the outside of the second plug outer shell 400, and the third plug outer shell 500 is sleeved on the outside of the first plug outer shell 340, and an internal thread 610 is provided on the inner side of one end of the positioning adapter 600, and the internal thread 610 is threadedly connected with the external thread 331.

[0027] Specifically, the plurality of pins 130 fixedly plugged into the first plastic core body 110 and the second plastic core body 120 are arranged in a certain order to meet specific electrical connection requirements. At the same time, the two groups of pins 130 of the first plastic core body 110 and the second plastic core body 120 can make the plug have the function of connecting two ends;

[0028] The two groups of pins 130 are connected and conducted by a stretchable wire 140, so that when the double-ended plug is used, the electrical signal can be stably transmitted, and the stretchable wire 140 can adapt to different usage scenarios, and when the plug is pulled by a certain external force, the electrical connection will not be disconnected;

[0029] The first insulating support sheet 210 and the second insulating support sheet 220 in the plastic core assembly support mechanism 200 are sleeved on the outside of the first plastic core body 110 and the second plastic core body 120 through the positioning mechanism 230, which can provide support and positioning for the plastic core body, ensuring that the plastic core body will not be displaced or shaken during use, thereby ensuring the relative position of the pin 130 is stable, and then ensuring the stability of the electrical connection;

[0030] The rubber core fixing mechanism 300 is installed on the outside of the rubber core body, and the first rubber core body 110 and the second rubber core body 120 can be firmly inserted into the plug inner shell 330 and the first plug outer shell 340, while the second plug outer shell 400, the third plug outer shell 500 and the positioning adapter body 600 are mutually sleeved, and the positioning adapter body 600 is threadedly connected to the plug inner shell 330. A tight plug structure is formed by nesting and threading, so that the plug is easy to assemble and can effectively prevent external dust and other debris from entering the plug and affecting the plug performance.

[0031] In this embodiment, there are seven pins 130 , and the ends of the pins 130 are each provided with a hollow cavity 131 , and the ends of the wires 140 are inserted into the hollow cavity 131 and fixed by welding.

[0032] Specifically, the number of the pins 130 is 7. A larger number of pins 130 can meet more electrical connection requirements and realize more types of signal transmission or power transmission. The hollow cavity 131 is set at the end of the pin 130. When the end of the wire 140 is inserted into the hollow cavity 131, the two groups of pins 130 are connected by welding and fixing, so that the connection between the pin 130 and the wire 140 is more stable, and it is not easy to loosen or disconnect when the plug is subjected to external forces such as vibration and pulling.

[0033] Moreover, the connection method of welding the wire 140 in the hollow cavity 131 also increases the conductive contact area, further ensuring the electrical connection stability of the plug when it is used in a double-ended connection.

[0034] In this embodiment, the positioning mechanism 230 includes a snap-fit ​​groove 231 opened inside the first insulating support sheet 210 and the second insulating support sheet 220. When the first insulating support sheet 210 and the second insulating support sheet 220 are snapped together, the snap-fit ​​groove 231 is snapped onto the outside of the stepped groove 232 provided at the ends of the first rubber core body 110 and the second rubber core body 120. The positioning mechanism 230 also includes a first positioning protrusion 233 fixedly connected to the outer side of the ends of the first insulating support sheet 210 and the second insulating support sheet 220. The first positioning protrusion 233 is snap-fitted with the first positioning groove 234 provided at both ends of the second insulating support sheet 220.

[0035] Specifically, when the first insulating support sheet 210 and the second insulating support sheet 220 are buckled together, the buckling groove 231 is buckled outside the stepped groove 232 at the ends of the first rubber core body 110 and the second rubber core body 120, so as to accurately locate the first insulating support sheet 210 and the second insulating support sheet 220 outside the rubber core body, and prevent them from being displaced in the radial direction;

[0036] The first positioning protrusions 233 on the outer sides of the ends of the first insulating support sheet 210 and the second insulating support sheet 220 are snap-fitted into the first positioning grooves 234 provided at both ends of the second insulating support sheet 220, so that the first insulating support sheet 210 and the second insulating support sheet 220 can be positioned in the axial direction, ensuring that the first insulating support sheet 210 and the second insulating support sheet 220 will not slide or misalign axially when they are outside the rubber core body, thereby ensuring the stability of the plug structure.

[0037] In this embodiment, the rubber core fixing mechanism 300 includes a first plug rubber core fixing sheet 310 and a second plug rubber core fixing sheet 320. The first plug rubber core fixing sheet 310 and the second plug rubber core fixing sheet 320 are respectively mounted on the outside of the first rubber core body 110 and the second rubber core body 120. An arc portion 311 is provided at one end of the first plug rubber core fixing sheet 310 and the second plug rubber core fixing sheet 320. The arc portions 311 of the first plug rubber core fixing sheet 310 and the second plug rubber core fixing sheet 320 are respectively engaged with the arc grooves provided on the inner sides of the plug inner shell 330 and the first plug outer shell 340.

[0038] Specifically, the first plug rubber core fixing piece 310 and the second plug rubber core fixing piece 320 are connected by the arc portion 311 and the arc groove of the plug inner shell 330 and the first plug outer shell 340, so that the rubber core body can form a stable connection with the plug inner shell 330 and the first plug outer shell 340. When the plug is subjected to external force during use, the arc portion 311 and the arc groove can effectively prevent the rubber core body from moving in the plug inner shell 330 and the first plug outer shell 340, thereby ensuring the stability of the position of the pin 130 and further ensuring the reliability of the electrical connection. In addition, the plug rubber core fixing piece made of insulating material and the rubber core body can also increase the insulation of the plug and improve the safety of the plug.

[0039] In this embodiment, a notch 332 is provided on the outer side of the external thread 331 of the plug inner shell 330 to prevent the wire clamp from rotating. A sealing ring installation groove 333 is provided at one end of the external thread 331 of the plug inner shell 330, and a sealing ring 334 is sleeved inside the sealing ring installation groove 333.

[0040] Specifically, when assembling the plug, when it comes to operating the wire clamp, the provided notch 332 can prevent the wire clamp from rotating, and the sealing ring 334 sleeved inside the sealing ring mounting groove 333 can prevent external impurities such as dust and moisture from entering the interior of the plug through the connection between the plug inner shell 330 and the positioning adapter body 600, thereby avoiding problems such as poor contact and corrosion in the plug, thereby improving the durability and reliability of the plug.

[0041] In this embodiment, a second positioning protrusion 335 is fixedly connected to the outside of the plug inner shell 330 , and the second positioning protrusion 335 is buckled and connected with a second positioning groove 510 provided on the third plug outer shell 500 .

[0042] Specifically, when the plug is assembled, the second positioning protrusion 335 cooperates with the second positioning groove 510 to ensure that the third plug shell 500 is accurately and stably mounted on the outside of the plug inner shell 330, thereby ensuring the efficiency of plug assembly. In addition, the snap-fit ​​connection method can also enhance the connection stability between the plug inner shell 330 and the third plug shell 500, thereby preventing relative displacement between the two.

[0043] In this embodiment, an annular protrusion 410 is provided on the outer side of one end of the second plug housing 400 , and a plurality of clamping claws 420 are provided on the other end of the second plug housing 400 . The annular protrusion 410 is buckled and connected with an annular groove provided inside the third plug housing 500 .

[0044] Specifically, when assembling the plug, the cooperation between the annular protrusion 410 and the annular groove can ensure that the second plug housing 400 is accurately sleeved inside the third plug housing 500, thereby achieving rapid and stable assembly. The plurality of clamping claws 420 provided on the second plug housing 400 can facilitate the sleeve clamping of the plug inner housing 330 during the assembly of the plug, thereby improving the assembly efficiency.

[0045] The engagement of the annular protrusion 410 with the annular groove can prevent the second plug housing 400 from being displaced relative to the third plug housing 500, thereby ensuring the stability of the entire external structure of the plug and the reliability of the plug when used in double-ended connection or in different environments.

[0046] In this embodiment, when the internal thread 610 and the external thread 331 are tightened, one end of the positioning adapter 600 is tightly abutted against one end of the plug inner shell 330 .

[0047] Specifically, when the internal thread 610 and the external thread 331 are tightened, one end of the positioning adapter body 600 is tightly abutted against one end of the plug inner shell 330. The tight abutment forms a stable connection structure between the positioning adapter body 600 and the plug inner shell 330, and the sealing ring 334 provided can effectively ensure the waterproofness of the plug.
