[0002] Since leakage of electrical connectors poses a great threat to people and equipment, the prior art, such as invention patent CN113013681A, discloses a fixed-point self-shorting electrical connector, including any two adjacent jacks in a seat shell connected via a metal connecting plate, the metal connecting plate is crimped between the front insulator of the hole and the middle insulator, a top hole is opened on the metal connecting plate, a top connection through hole is opened on the front insulator of the hole corresponding to the top hole, an insulating plunger is slidably arranged in the top connection through hole, a through connection through hole is opened on the middle insulator corresponding to the top hole, a front probe, a spring, and a rear probe are built into the through connection through hole, the front probe is connected to the rear probe via a spring, the front probe is pressed against the top hole via the spring, the rear probe is pressed against the circuit board, and the circuit board is crimped between the middle insulator and the rear insulator of the hole; a plurality of ejector pins corresponding to the insulating plunger are passed through the needle insulator to push the front probe out of the top hole. When the plug and socket are separated, the front probe is reset by the spring to connect the short circuit when the shell is not completely separated, and the connector is automatically short-circuited. When the plug and socket are plugged in, the front probe is pushed out of the top hole by the ejector pin to release the short circuit. However, the above device needs to be equipped with an ejector pin, and the structure is relatively complicated. Utility Model Content

[0003] The purpose to be achieved by the utility model is to provide a self-short-circuit electric connector, which solves the problem of complex structure of the electric connector and makes the structure of the electric connector simpler.

[0004] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a self-short-circuiting electrical connector, comprising a plug and a socket adapted to the plug, the plug comprising a first insulator and sockets arranged at intervals on the first insulator, the socket comprising a second insulator and conductive pins arranged thereon with corresponding sockets, the conductive pins passing through the second insulator, adjacent conductive pins forming an accommodating cavity, a short-circuit member and a first elastic member arranged between the short-circuit member and the inner wall of the accommodating cavity being slidably arranged in the accommodating cavity, the short-circuit member comprising a short-circuit portion and a push rod portion fixedly connected to the short-circuit portion, an opening for the push rod portion to pass through the second insulator is provided on the inner wall of the accommodating cavity, the push rod portion is located on the same side as the conductive pin after passing through the second insulator, the short-circuit member has a tendency to pass through the second insulator and the short-circuit portion contacts the adjacent conductive pins under the elastic force of the first elastic member, and when the plug is plugged into the socket, the surface of the first insulator pushes the push rod portion to separate the short-circuit portion from the adjacent conductive pins.

[0005] After adopting the above technical solution, the utility model has the following advantages: First, in the state where the plug and the socket are not plugged together, due to the action of the first elastic member, the short-circuit member automatically makes the short-circuit portion contact the adjacent conductive pin to form a short circuit, which can effectively prevent electrical accidents caused by misoperation, such as electrostatic discharge or accidental electric shock, and improve the use safety. Second, when the plug and the socket are correctly plugged together, the push rod portion is directly pushed on the outside by the first insulator, without setting a thimble, which simplifies the structure and the operation process, avoids complex mechanical insertion actions, and does not require additional alignment and insertion actions, improving the convenience and efficiency of use, reducing the mechanical wear caused by plugging and unplugging, and prolonging the service life of the components.

[0006] Further, a shielding cover is provided above the conductive pin on the socket, and an inclined guiding surface is provided below the conductive pin on the socket. The shielding cover and the guiding surface enclose a guiding channel for guiding the plug to be plugged into the socket.

[0007] Adopting the above technical solution, the shielding cover covers above the conductive pin, effectively preventing dust, moisture and external foreign objects from entering the socket, protecting the conductive pin from corrosion or physical damage, and also preventing accidental touch, improving the use safety. The design of the guiding channel helps users to more accurately position and guide the alignment of the plug and the socket visually and tactilely, especially in the case of poor visibility or limited space, improving the accuracy and efficiency of plugging.

[0008] Further, a limiting portion is provided on the plug, and a locking member is provided on the inner wall of the guiding channel. When the plug is plugged into the socket, the locking member cooperates with the limiting portion to lock, so as to lock the plug on the socket.

[0009] Adopting the above technical solution, the cooperation and locking of the locking member and the limiting portion ensure a firm connection between the plug and the socket, can minimize the situation of the plug falling off caused by accidental touch or pulling, and can significantly reduce the risk of electrical safety accidents.

[0010] Further, the limiting portion includes a limiting groove provided on the plug, and the locking member includes a movable groove provided on the guiding surface, a ball plunger slidably disposed in the movable groove, and a second elastic member connecting the ball plunger and the inner wall of the movable groove. The ball plunger has a tendency to protrude from the inner wall of the movable groove under the elastic force of the second elastic member.

[0011] With the above technical solution, the continuous outward elastic force provided by the second elastic member ensures that the ball plunger always maintains a certain pressure on the outside world. Once it engages with the limit groove, a firm physical lock can be formed, effectively preventing the plug from accidentally coming out under vibration or external force, enhancing the stability of the connection. Secondly, the unlocking process is simple. The user only needs to apply an appropriate external force to overcome the resistance of the second elastic member and retract the ball plunger, facilitating the removal of the plug.

[0012] Furthermore, four conductive pins are provided around each of the push rod portions, and the conductive pins are arranged in an array along the circumferential direction.

[0013] With the above technical solution, the circumferentially arranged conductive pins form a self-aligning mechanism. Even in the case of blind insertion or inaccurate alignment, there is a high probability that at least some of the conductive pins can be correctly connected, improving the convenience and fault tolerance of the connection, and also enabling the first insulator to more accurately push the push rod portion.

[0014] Furthermore, the length of the conductive pin protruding from the second insulator is L1, and the length of the push rod portion protruding from the second insulator is L2, and L1 > L2.

[0015] With the above technical solution, it ensures the establishment of an electrical connection, that is, the short-circuit state is released only after the contact between the conductive pin and the jack, avoiding the risk of the circuit being powered on when the plug is not fully in place, greatly improving the operation safety. Secondly, when the user plugs and unpluggs the plug, they can feel a clear sequence of steps, that is, first feel a "click" sound when the electrical connection is established, and then feel the feeling of the push rod portion being pushed open. This feedback enhances the certainty of the operation and user satisfaction.

[0016] Furthermore, a third insulator is provided in the accommodation cavity. The third insulator has an insulating cavity with a front end communicating with the opening. The short-circuit portion and the first elastic member are arranged in the insulating cavity. Conductive ribs are provided on the adjacent conductive pins at the front end of the installation cavity, and the first elastic member pushes the short-circuit portion into contact with the conductive ribs.

[0017] With the above technical solution, the setting of the conductive ribs makes the short-circuit contact points concentrated on the conductive ribs rather than the entire conductive pin. The introduction of the third insulator effectively isolates the non-contact part of the short-circuit portion from the conductive pin, greatly enhancing the electrical insulation performance, avoiding potential short-circuit risks, and improving the use safety.

[0018] Furthermore, the jacks are arranged in an array in the same direction.

[0019] With the above technical solution, the jack array in the same direction helps to simplify the alignment work of the jacks and the conductive pins. Only one or several alignments need to be completed to align all the jacks and conductive pins.

[0020] Further, a tail cover facilitating operation is provided on the plug, and the tail cover and the plug are detachably connected by screws.

[0021] With the above technical solution, in addition to facilitating operation, the tail cover can also provide physical protection for the plug and the connection part. The detachable tail cover design enables the tail cover to be separated from the plug first during the installation process, facilitating alignment with the socket for insertion. After completion, the tail cover is screwed on for fixation, simplifying the operation process. At the same time, when maintenance or plug replacement is required, it can also be quickly disassembled, improving the maintenance efficiency.

[0022] Further, an installation cavity for installing a first insulator is provided on the plug. The installation cavity is provided with an installation step surface and a snap ring, and the first insulator is snap-connected to the installation step surface through the snap ring.

[0023] With the above technical solution, the snap ring fixing method allows for quick and easy installation or replacement of the first insulator. The snap ring can provide stable radial pressure to ensure that the first insulator is firmly fixed in the installation cavity and is not easily detached even under vibration or external force, enhancing the mechanical stability of the plug.

[0039] The technical solution of the present utility model will be described in detail below with specific embodiments. These several specific embodiments can be combined or replaced according to the actual situation. For the same or similar concepts or processes, they may not be repeated in some embodiments.

[0040] As Figures 1 to 8 shown, the present utility model provides a self-shorting electrical connector, which includes a plug 100 and a socket 200 adapted to the plug 100. The plug 100 includes a first insulator 110 and a plurality of jacks 111 spaced apart on the first insulator 110. The socket 200 includes a second insulator 210 and conductive pins 220 provided thereon corresponding to the jacks 111. The conductive pins 220 penetrate through the second insulator 210. An accommodation cavity 221 is formed by surrounding between adjacent conductive pins 220. A shorting member and a first elastic member 240 provided between the shorting member and the inner wall of the accommodation cavity 221 are slidably disposed in the accommodation cavity 221. The shorting member includes a shorting portion 231 and a push rod portion 232 fixedly connected to the shorting portion 231. An opening 222 for the push rod portion 232 to penetrate through the second insulator 210 is formed on the inner wall of the accommodation cavity 221. After the push rod portion 232 penetrates through the second insulator 210, it is on the same side as the conductive pin 220. The shorting member has a tendency to make the push rod portion 232 penetrate through the second insulator 210 and the shorting portion 231 contact the adjacent conductive pin 220 under the elastic force of the first elastic member 240. In the state where the plug 100 and the socket 200 are not inserted, the shorting member automatically makes the shorting portion 231 contact the adjacent conductive pin 220 due to the action of the first elastic member 240, forming a short circuit, which can effectively prevent electrical accidents caused by misoperation, such as electrostatic discharge or accidental electric shock, and improve the use safety. Secondly, when the plug 100 and the socket 200 are inserted, the push rod portion 232 is directly pushed through the surface of the first insulator 110 to separate the shorting portion 231 from the adjacent conductive pin 220, without setting a thimble, which simplifies the structure and also simplifies the operation process, without additional alignment and insertion actions, avoiding complex mechanical insertion actions, simplifying the operation process, improving the convenience and efficiency of use, and also reducing the mechanical wear caused by plugging and unplugging, and extending the service life of the components.

[0041] It should be noted that a through hole 211 communicating with the opening 222 is provided on the second insulator 210, allowing the push rod portion 232 to pass through the second insulator 210 to the outside.

[0042] To further enable the first insulator 110 to more accurately push the push rod portion 232, the push rod portion 232 and the conductive pin 220 are arranged in parallel. A shielding cover 201 is provided above the conductive pin 220 on the socket 200, that is, the shielding cover 201 is located above the push rod portion 232, effectively preventing dust, moisture, and external foreign objects from entering the interior of the socket 200, protecting the conductive pin 220 from corrosion or physical damage, and also preventing accidental touch, improving the safety of use. Secondly, an inclined guiding surface 202 is provided below the conductive pin 220 on the socket 200. The shielding cover 201 and the guiding surface 202 enclose a guiding channel 203 for guiding the plug 100 to be inserted into the socket 200. The design of the guiding channel 203 helps users to more accurately position and guide the alignment of the plug 100 and the socket 200 visually and tactilely, especially in the case of poor visibility or limited space, improving the accuracy and efficiency of insertion. Since the push rod portion 232 and the conductive pin 220 are arranged in parallel, the surface of the first insulator 110 can also more accurately push the push rod portion 232.

[0043] Furthermore, the jacks 111 are arranged in an array in the same direction, and the corresponding conductive pins 220 are also arranged to match the jacks 111. The array of jacks 111 in the same direction helps to simplify the alignment work of the jacks 111 and the conductive pins 220. Only by completing the alignment of one or several of them can all the jacks 111 and the conductive pins 220 be aligned, and it can also make the plug 100 and the socket 200 more beautiful.

[0044] Specifically, four conductive pins 220 are provided around each push rod portion 232, and the conductive pins 220 are arranged in a circumferential array. The four conductive pins 220 and the short-circuiting member form a single electrical component. The circumferentially arranged conductive pins 220 form a self-aligning mechanism. Even in the case of blind insertion or inaccurate alignment, there is a high probability that at least a part of the conductive pins 220 can be correctly connected, improving the convenience and fault tolerance of connection, and also enabling the first insulator 110 to more accurately push the push rod portion 232.

[0045] In the prior art, the self-short-circuit unlocking of the socket 200 is synchronized with the plug 100 and the socket 200, resulting in the circuit being powered on before the plug 100 is fully in place, which is prone to leakage risks. Therefore, in the prior art, the length of the conductive pin 220 protruding from the second insulator 210 is L1, and the length of the push rod portion 232 protruding from the second insulator 210 is L2, where L1 > L2, ensuring the establishment of electrical connection, that is, the short-circuit state is released only after the conductive pin 220 contacts the jack 111, avoiding the risk of the circuit being powered on before the plug 100 is fully in place, greatly improving the operation safety. Secondly, when the user plugs and unpluggs the plug 100, a clear sequence of steps can be felt, that is, first, the establishment of electrical connection with a "click" sound is felt, and then the feeling of the push rod portion 232 being pushed away. This feedback enhances the certainty of operation and user satisfaction.

[0046] To reduce the situation where the plug 100 falls off due to accidental touch or pulling, a limiting portion is provided on the plug 100, and a locking member is provided on the inner wall of the guiding channel 203. When the plug 100 is inserted into the socket 200, the locking member cooperates with the limiting portion to lock, so as to lock the plug 100 on the socket 200. The cooperation and locking of the locking member and the limiting portion ensure a firm connection between the plug 100 and the socket 200, and can significantly reduce the risk of electrical safety accidents.

[0047] Specifically, the limiting portion includes a limiting groove 120 provided on the plug 100, and the locking member includes a movable groove 204 provided on the guiding surface 202, a ball plunger 205 slidably disposed in the movable groove 204, and a second elastic member 206 connecting the ball plunger 205 to the inner wall of the movable groove 204. The ball plunger 205 has a tendency to protrude from the inner wall of the movable groove 204 under the elastic force of the second elastic member 206, ensuring that the ball plunger 205 always maintains a certain pressure on the outside world. Once it engages with the limiting groove 120, a firm physical lock can be formed, effectively preventing the plug 100 from accidentally coming out under vibration or external force, enhancing the stability of the connection. Secondly, the unlocking process is simple. The user only needs to apply an appropriate external force to overcome the resistance of the second elastic member 206 and retract the ball plunger 205, facilitating the removal of the plug 100.

[0048] To further improve the usage safety, a third insulator 250 is provided in the accommodation cavity 221. The third insulator 250 has an insulating cavity 251 with its front end communicating with the opening 222. The short - circuit part 231 and the first elastic member 240 are arranged in the insulating cavity 251. A conductive rib 223 is provided on the adjacent conductive pins 220 at the front end of the installation cavity 140. The first elastic member 240 pushes the short - circuit part 231 into contact with the conductive rib 223. The arrangement of the conductive rib 223 makes the short - circuit contact point concentrated on the conductive rib 223 rather than the entire conductive pin 220. The introduction of the third insulator 250 effectively isolates the non - contact part of the short - circuit part 231 from the conductive pin 220, greatly enhancing the electrical insulation performance, avoiding potential short - circuit risks, and improving the usage safety.

[0049] To facilitate the use of the plug 100, the plug 100 is also provided with a tail cover 130 that is conducive to operation. The tail cover 130 and the plug 100 are detachably connected by screws. In addition to facilitating operation, the tail cover 130 can also provide physical protection for the plug 100 and the connection part. The detachable design of the tail cover 130 enables the tail cover 130 to be separated from the plug 100 first during the installation process, facilitating alignment with the socket 200 for insertion. After completion, the tail cover 130 is screwed on for fixation, simplifying the operation process. At the same time, when the plug 100 needs to be repaired or replaced, it can also be quickly disassembled, improving the maintenance efficiency.

[0050] Moreover, since the first insulator 110 is extruded by the push rod part 232 for a long time, it is prone to deformation. Therefore, the plug 100 is also provided with an installation cavity 140 for installing the first insulator 110. The installation cavity 140 is provided with an installation step surface 141 and a snap ring 150. The first insulator 110 is clamped on the installation step surface 141 by the snap ring 150. The fixing method of the snap ring 150 allows for quick and simple installation or replacement of the first insulator. The snap ring 150 can provide stable radial pressure to ensure that the first insulator 110 is firmly fixed in the installation cavity 140 and is not easily detached even under vibration or external force, enhancing the mechanical stability of the plug 100.

[0051] During use, as Figure 5 shown, when the plug 100 and the socket 200 are separated, the short - circuit member is under the elastic force of the first elastic member 240 and has the push rod part 232 passing through the second insulator 210 and the short - circuit part 231 contacting the adjacent conductive pins 220, short - circuiting the adjacent conductive pins 220;

[0052] As Figure 1As shown, when the plug 100 and the socket 200 are plugged in, the conductive pin 220 is first inserted into the socket 111, and an electrical connection is established with a "click" sound, followed by the push rod portion 232 being pressed by the first insulator 110, so that the short-circuit portion 231 is separated from the conductive rib 223, and the self-short circuit of the socket 200 is released until the surface of the first insulator 110 contacts the surface of the second insulator 210, and the ball plunger 205 is inserted into the limiting groove 120, so that the plug 100 and the socket 200 can achieve a reliable plug-in connection.

[0053] It should be noted that in the present invention, a short-circuit component can be selectively arranged in the accommodating cavity 221, so that the conductive pins 220 on the socket 200 can selectively achieve self-short-circuit protection.

[0054] It should be noted that the first elastic member 240 and the second elastic member 206 can be components with good elasticity such as springs, so that the short-circuit member and the ball plunger 205 can be quickly reset.

[0055] In addition to the above-mentioned preferred embodiments, the present invention also has other implementation modes. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work are within the scope of protection requested by the present invention.
