Description

Technical Field

[0001] The present invention relates to the technical field of electric connectors, in particular to an electric connector, a joint mechanism and a test plug wiring system. Background Art

[0002] With the improvement of the intelligence level of electrical equipment, the electrical connections of its internal and external circuits have become more complicated, the application of various electrical connectors has increased accordingly, and the tasks of whole machine wiring inspection and electrical debugging have become more arduous.

[0003] Usually, electrical connectors are used for electrical connections inside and outside the equipment. When the equipment is put into operation and repaired and debugged, it is often necessary to insert the plugs on various testing instruments into the corresponding sockets on the equipment to be tested for electrical testing. During this process, the staff needs to frequently plug and unplug the plugs. If the plugs are not tightly inserted, the plugs may accidentally fall off due to vibration or external force, which may cause equipment failure. After the debugging work is completed, the staff needs to unplug the plug again. Repeated plugging and unplugging is time-consuming, labor-intensive, and inefficient. If too much force is used, it will not only consume physical strength, but also affect the stability of the socket.

[0004] Therefore, in order to ensure the reliability of electrical connection, enable the plug and socket to be plugged and locked, make the plugging and unplugging operations easier, and improve efficiency, we have proposed an electrical connector, a connector mechanism, and a test plug wiring system. Summary of the invention

[0005] In view of the above technical problems that the plug needs to be frequently plugged and unplugged during the commissioning, maintenance and debugging of the existing equipment, the plug and the socket need to be locked together and plugged and unplugged with less effort, the electrical connector in the present invention is proposed.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: an electrical connector, comprising a first connecting member, comprising a first surface having a pressure-bearing portion and a second surface having a limiting portion; and a second connecting member, comprising a fixing portion and an extrusion portion, wherein the fixing portion can be buckled on the limiting portion along a first direction, and when the fixing portion is buckled on the limiting portion, the extrusion portion is opposite to the pressure-bearing portion; and when the fixing portion moves relative to the limiting portion, the extrusion portion can generate at least a second direction force on the pressure-bearing portion, and the angle between the first direction and the second direction is not equal to 0°.

[0007] As a preferred solution of the electrical connector of the present invention, wherein: the first connecting member is provided with a connecting hole, the fixing portion can pass through the connecting hole of the first connecting member, and be buckled on the limiting portion through the fixing portion.

[0008] As a preferred solution of the electrical connector of the present invention, the fixing portion and the extrusion portion extend in the same direction.

[0009] As a preferred solution of the electrical connector of the present invention, the fixing portion and the extrusion portion extend in the same direction.

[0010] As a preferred solution of the electrical connector of the present invention, the fixing portion includes an inner hook surface corresponding to the limiting portion, and when the fixing portion is buckled on the limiting portion along the first direction, the inner hook surface is in contact with the limiting portion.

[0011] As a preferred solution of the electrical connector of the present invention, wherein: the second connecting member can rotate relative to the first connecting member, when the fixing part moves relative to the limiting part by rotating, the extrusion part can generate a force in a second direction on the pressed part by rotating in the same direction.

[0012] As a preferred solution of the electrical connector of the present invention, when the fixing portion is buckled on the limiting portion along the first direction, there is an adapting space between the extruding portion and the pressed portion.

[0013] As a preferred solution of the electrical connector of the present invention, wherein: a guide surface is provided at the end of the fixing portion, and the fixing portion can cross over the first connecting member through the guide surface; or, a guide surface corresponding to the end of the fixing portion is provided on the first connecting member, so that the fixing portion can cross over the first connecting member from the guide surface.

[0014] As a preferred solution of the electrical connector of the present invention, wherein: the second connecting member can perform linear motion relative to the first connecting member away from the limiting portion, and the pressed portion has a tendency to gradually approach the second surface from the direction close to the connecting hole to the direction away from the connecting hole; when the fixing portion moves away from the limiting portion through linear motion, the extrusion portion can generate a force in the second direction on the pressed portion.

[0015] As a preferred solution of the electrical connector of the present invention, a slot is formed between the fixing portion and the extrusion portion, and the slot has an extrusion surface that matches the pressed portion.

[0016] As a preferred solution of the electrical connector of the present invention, a slot is formed between the fixing portion and the extrusion portion, and the slot has an extrusion surface that matches the pressed portion.

[0017] As a preferred solution of the electrical connector of the present invention, the second connector further comprises an operating portion; the operating portion is connected to the extrusion portion, and the operating portion is arranged on the other end of the extrusion portion relative to the fixing portion.

[0018] One beneficial effect of the present invention is that by providing the first connecting member and the second connecting member, the fixing portion can be buckled on the limiting portion along the first direction to form a connection. When the two need to be disengaged, by making the extrusion portion squeeze the pressed portion, not only can the fixing portion and the limiting portion be disengaged, but the extrusion portion can also generate a force in the second direction on the pressed portion, thereby lifting the first connecting member, achieving a labor-saving effect to a certain extent.

[0019] In view of the above-mentioned technical problems that the plug and the socket need to be locked when they are plugged in, but need to be labor-saving and easy to improve efficiency when the plug and the socket are disengaged, the connector mechanism in the present invention is proposed.

[0024] Another beneficial effect of the present invention is that when the plug and the socket are tightly plugged in, the fixing portion can be buckled on the limiting portion along the first direction, and when the plug and the socket need to be separated, the fixing portion is moved away from the limiting portion by the operating portion, while the extrusion portion generates a force on the pressed portion to move away from the extrusion portion, providing assistance to separate the plug and the socket.

[0025] Considering that during the commissioning, maintenance and debugging of equipment, it is necessary to insert the plug on the detection instrument into the equipment to be detected to detect the on-off of the internal circuit, thus the test plug wiring system in the present invention is proposed.

[0027] Another beneficial effect of the present invention is that the plug can be arranged on the detection instrument, and the socket is correspondingly arranged on the device to be tested. When the plug is inserted into the socket, the on-off condition of the internal electrical circuit of the device can be tested. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0052] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0053] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0054] Example 1, reference Figure 1 to Figure 17 , which is the first embodiment of the present invention, provides an electrical connector.

[0055] The electrical connector includes: a first connecting member 100, which includes a first surface M-1 having a pressure-bearing portion 101 and a second surface M-2 having a limiting portion 102; and a second connecting member 200, which includes a fixing portion 201 and an extruding portion 202, wherein the fixing portion 201 can be buckled on the limiting portion 102 along a first direction, and when the fixing portion 201 is buckled on the limiting portion 102, the extruding portion 202 is opposite to the pressure-bearing portion 101; and, when the fixing portion 201 moves relative to the limiting portion 102, the extruding portion 202 can generate at least a second direction of force on the pressure-bearing portion 101, and the angle between the first direction and the second direction is not equal to 0°.

[0056] The first connector 100 in this embodiment is actually a connection structure provided on the socket of the device to be tested (the device to be tested may be a power protection device, such as a power protection cabinet), and the connection structure is used to fix the plug plugged into the socket. In one embodiment, the first connector 100 may be a flat plate structure with a certain thickness, and is fixed to the outer edge of the socket.

[0057] Specifically, a side surface of the first connector 100 corresponding to the plug-in direction is the first surface M-1, and the pressure-bearing portion 101 is a pressure-bearing area on the first surface M-1. The pressure-bearing area can be a plane coinciding with the first connector 100, or a plane parallel to the first connector 100, or an inclined plane forming a certain angle with the first connector 100. Of course, when the pressure-bearing portion 101 is not completely a plane (such as a slightly curved surface), it can still be implemented.

[0058] The other side surface of the first connecting member 100 relative to the first surface M-1 is the second surface M-2, and the limiting portion 102 is a limiting area existing on the second surface M-2. The limiting area can be a plane overlapping with the first connecting member 100, or a plane parallel to the first connecting member 100. Of course, the limiting portion 102 can also be other curved surface shapes, but at least it should ensure that the fixing portion 201 can be hooked thereon.

[0059] The second connecting member 200 in this embodiment is actually a connecting structure arranged on the plug of the detection instrument (the detection instrument can be an HP90 tester, a multi-circuit continuity tester, etc.). When the detection instrument is fixed to the socket of the device to be tested through the plug, the locking effect of the second connecting member 200 on the first connecting member 100 can achieve a fixed connection between the detection instrument and the device to be tested. Of course, the second connecting member 200 and the first connecting member 100 can also be disassembled to achieve the removal of the detection instrument.

[0060] Specifically, the second connecting member 200 includes a fixing portion 201 and an extrusion portion 202. The fixing portion 201 is a structure for buckling with the limiting portion 102 on the first connecting member 100, which may be a hook-shaped structure; the extrusion portion 202 is a structure for extruding the pressure-bearing portion 101 on the first connecting member 100, which may be a block structure, a flat plate structure or other irregular structures that can produce an extrusion effect on the pressure-bearing portion 101.

[0061] The present invention sets, as Figure 6~Figure 17 As shown, the first direction is from the edge of the first connector 100 to the center of the first connector 100, that is, the direction of F1 in the figure; the second direction is the direction of the plug being plugged into the socket, that is, the direction of F2 in the figure.

[0062] When the detection instrument is fixed on the socket of the device to be tested through the plug to realize the locking function, the fixing part 201 can be buckled on the limiting part 102 along the first direction; when the plug of the detection instrument is to be unplugged from the socket of the device to be tested to realize the unlocking function, the fixing part 201 can be operated to move away from the limiting part 102, and when the fixing part 201 moves relative to the limiting part 102, the extrusion part 202 can generate at least a second direction of force on the pressed part 101. The present invention stipulates that: the angle between the first direction and the second direction is not equal to 0. The above-mentioned plugging and unplugging process between the plug and the socket can exist in the following two different implementations:

[0063] In the first embodiment, rotary extrusion is used. Figure 6~Figure 13, the second connecting member 200 is hingedly arranged on the plug of the detection instrument, and it can be buckled on the pressure-bearing part 101 of the first connecting member 100 through its hook-shaped fixing part 201 to achieve locking. When unlocking is required, the second connecting member 200 can be toggled so that the second connecting member 200 can rotate relative to the first connecting member 100. In this process, when the fixing part 201 moves away from the limiting part 102 by rotation, the extrusion part 202 can generate a second direction of force on the pressure-bearing part 101 by rotating in the same direction, so that the first connecting member 100 can gradually move away from the plug of the detection instrument through the action of the lever, and finally disengage and unlock. Therefore, in practice, the operator only needs a toggling force on the second connecting member 200 to achieve the two functions of "unlocking" and "assisting to release" at the same time, and no longer needs to independently apply the "toggling" and "external pulling" forces at the same time, which is labor-saving and convenient.

[0064] In the second embodiment, linear sliding extrusion is used. Figure 14~Figure 17 , the second connector 200 is arranged on the plug of the detection instrument by sliding fit, and it can be buckled on the pressure-bearing part 101 of the first connector 100 through its hook-shaped fixing part 201 to achieve locking. The sides of the extrusion part 202 and the pressure-bearing part 101 opposite to each other are provided with slope surfaces that can fit each other. When unlocking is required, the second connector 200 can be slid outward so that the second connector 200 can slide relative to the first connector 100. In this process, when the fixing part 201 moves away from the limiting part 102 by lateral sliding, the extrusion part 202 can generate a component force in the second direction on the first connector 100 by squeezing the pressure-bearing part 101 with the slope, so that the first connector 100 can also gradually move away from the plug of the detection instrument, and finally disengage and unlock. Therefore, in practice, the operator only needs an outward sliding force on the second connector 200 to achieve the two functions of "unlocking" and "assisting release" at the same time, and no longer needs to pinch and pull out at the same time, which is labor-saving and convenient.

[0065] In summary, the present invention buckles the fixing portion 201 on the second connecting member 200 onto the limiting portion 102 of the first connecting member 100, so that the connection between the socket and the plug is tighter, and the plug can be effectively prevented from falling off due to accidental collision or pulling; and when the socket and the plug need to be separated, the fixing portion 201 is moved away from the limiting portion 102, and at the same time of disengagement, the extrusion portion 202 squeezes the pressed portion 101, thereby providing an assisting force to lift the plug, achieving a labor-saving effect, while also providing safety protection.

[0066] Example 2, reference Figure 1 to Figure 17, which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but further, the fixing portion 201 can be buckled on the limiting portion 102 through two implementation methods.

[0067] The first connecting member 100 is provided with a connecting hole 103 , and the fixing portion 201 can pass through the connecting hole 103 of the first connecting member 100 and be buckled on the limiting portion 102 through the fixing portion 201 .

[0068] Specifically, the connecting hole 103 is a hole that passes through the first surface M-1 and the second surface M-2 on the first connecting member 100. The connecting hole 103 can be set at any position in the middle of the first connecting member 100, and can also be set at the edge of the first connecting member 100. The connecting hole 103 is mainly used to provide a movement space for the fixing part 201 to buckle toward the limiting part 102. The side wall of the connecting hole 103 can be a vertical plane, an inclined surface with a certain slope, or a surface with a certain curvature. All of the above situations can be implemented.

[0069] Preferably, the fixing portion 201 and the pressing portion 202 extend in the same direction.

[0070] It should be noted that the fixing portion 201 and the extruding portion 202 need to extend in the same direction. Figure 5 As shown, if the fixing portion 201 and the extruding portion 202 do not extend in the same direction, when the fixing portion 201 moves relative to the limiting portion 102, although the release effect can be achieved, the extruding portion 202 cannot generate a force in the second direction on the pressed portion 101, and thus cannot provide assistance to lift the plug.

[0071] Preferably, the fixing portion 201 and the pressing portion 202 extend in the same direction.

[0072] Preferably, the fixing portion 201 includes an inner hook surface 201 a corresponding to the limiting portion 102 . When the fixing portion 201 is buckled onto the limiting portion 102 along the first direction, the inner hook surface 201 a is in contact with the limiting portion 102 .

[0073] When the fixing portion 201 has a tendency to move along the first direction and buckle toward the limiting portion 102 , there is a surface on the fixing portion 201 that can fit with the limiting portion 102 , and the surface is defined as the inner hook surface 201 a .

[0074] The inner hook surface 201a is mainly used to form a stable connection between the first connector 100 and the second connector 200. When the inner hook surface 201a is attached to the limiting portion 102, it can prevent the first connector 100 and the second connector 200 from being easily separated, that is, the tight connection between the plug and the socket is strengthened to prevent loosening; and the inner hook surface 201a can be a plane on the fixing portion 201, or a curved surface with certain protrusions, such as Figure 4 As shown, as long as there is an area on the inner hook surface 201 a that can fit with the limiting portion 102 , it will be sufficient.

[0075] Preferably, in the first embodiment, the second connecting member 200 can rotate relative to the first connecting member 100, and when the fixing portion 201 moves relative to the limiting portion 102 by rotating, the extrusion portion 202 can generate a force in a second direction on the pressed portion 101 by rotating in the same direction.

[0076] Preferably, when the fixing portion 201 is buckled onto the limiting portion 102 along the first direction, an adaption space K exists between the extruding portion 202 and the pressed portion 101 .

[0077] In order to ensure a tight fit between the plug and the socket and prevent the plug from being loosened due to accidents such as collision or pulling, a second connecting member 200 is provided so that the fixing portion 201 is buckled on the limiting portion 102, and the fixing portion 201 can be buckled on the limiting portion 102 by linear motion or rotational motion. If the fixing portion 201 buckles the limiting portion 102 by rotational motion, the extruding portion 202 will rotate together with the fixing portion 201; in order to ensure that the rotation of the extruding portion 202 does not affect the pressed portion 101 while the fixing portion 201 completes the action of buckling the limiting portion 102, a space needs to be provided to allow the extruding portion 202 to rotate in this space, such as Figure 6~Figure 13 As shown, this space is the adaptation space K.

[0078] Preferably, a guide surface M is provided at the end of the fixing portion 201, and the fixing portion 201 can cross the first connecting member 100 through the guide surface M; or, a guide surface M corresponding to the end of the fixing portion 201 is provided on the first connecting member 100, so that the fixing portion 201 can cross the first connecting member 100 from the guide surface M.

[0079] When the fixing portion 201 is buckled with the limiting portion 102 by rotating, the guide surface M is mainly used to guide the fixing portion 201 to rotate to a certain extent and buckle the limiting portion 102; Figure 6 , Figure 8 , Fig.10 , Fig.12 As shown, the guide surface M is provided at the end of the fixing portion 201. When the fixing portion 201 passes through the connecting hole 103, the guide surface M on the fixing portion 201 cooperates with the side wall of the connecting hole 103, so that the fixing portion 201 rotates to a certain extent and buckles the limiting portion 102; Figure 7 , Fig. 9 , Fig.11 , Fig.13As shown, the guide surface M is provided on the first connecting member 100 . When the fixing portion 201 passes through the connecting hole 103 , the end of the fixing portion 201 will cooperate with the guide surface M on the first connecting member 100 , thereby guiding the fixing portion 201 to buckle the limiting portion 102 .

[0080] It should be mentioned that the guide surface M may be a plane with a certain inclination. Of course, an incomplete plane with a certain inclination (such as a slightly curved surface) may also be implemented.

[0081] When the second connecting member 200 passes through the connecting hole 103 on the first connecting member 100 by rotating, so that the fixing portion 201 is buckled on the inner hook surface 201a, the following situations can be specifically described:

[0082] The first case is: Figure 6 As shown, when the plug is inserted into the socket, the second connector 200 on the plug will engage with the first connector 100 on the socket. Specifically, the fixing portion 201 will pass through the connecting hole 103. Under the action of the guide surface M, the fixing portion 201 will rotate and hook the limiting portion 102 along the first direction. At this time, the extrusion portion 202 will rotate together with the fixing portion 201. Through the provided adaptation space K, the extrusion portion 202 rotates in the adaptation space K without affecting the pressed portion 101. Therefore, after the fixing portion 201 hooks the limiting portion 102, a stable connection between the plug and the socket can be formed.

[0083] According to Figure 6 In the implementation mode, when the plug needs to be unplugged, the fixing portion 201 only needs to be rotated away from the limiting portion 102, so that the fixing portion 201 is released, and at the same time, the extruding portion 202 rotates in the same direction, so that the extruding portion 202 rotates through the adaptation space K and provides an extrusion force in at least the second direction to the pressed portion 101, so that the plug connected to the second connecting member 200 is lifted upward, thereby separating the plug from the socket, and improving the safety during the plugging and unplugging process.

[0084] The second situation is: Figure 7 As shown, when the plug is inserted into the socket, the second connector 200 on the plug will engage with the first connector 100 on the socket. Specifically, the fixing portion 201 will pass through the connecting hole 103, and the guide surface M is arranged on the side wall of the connecting hole 103. When the fixing portion 201 passes through, it will flexibly cooperate with the guide surface M, so that the fixing portion 201 rotates and hooks the limiting portion 102 along the first direction. At this time, the extruding portion 202 will rotate together with the fixing portion 201. Through the provided adaptation space K, the extruding portion 202 can rotate in the adaptation space K without affecting the pressed portion 101. Therefore, after the fixing portion 201 hooks the limiting portion 102, a stable connection between the plug and the socket can be formed.

[0085] According to Figure 7 In the implementation mode, when the plug needs to be unplugged, the fixing portion 201 only needs to be rotated away from the limiting portion 102, so that the fixing portion 201 can be released. At the same time, the extruding portion 202 can rotate in the same direction, so that the extruding portion 202 rotates through the adaptation space K and provides an extrusion force in at least the second direction to the pressed portion 101, so that the plug connected to the second connecting member 200 can be lifted upward, so that the plug is separated from the socket, and safety is also provided during the plugging and unplugging process.

[0086] The third situation is: Figure 8 As shown, the pressed portion 101 on the first connecting member 100 is an inclined plane with a certain angle. When the plug is inserted into the socket, the second connecting member 200 on the plug can still be engaged with the first connecting member 100 on the socket. Specifically, the fixing portion 201 passes through the connecting hole 103. Under the action of the guide surface M, the fixing portion 201 rotates and hooks the limiting portion 102 along the first direction. At this time, the extruding portion 202 rotates with the fixing portion 201. Through the provided adaptation space K, the extruding portion 202 rotates in the adaptation space K without affecting the pressed portion 101. Therefore, after the fixing portion 201 hooks the limiting portion 102, a stable connection between the plug and the socket can be formed.

[0087] According to Figure 8 In the implementation mode, when the plug needs to be unplugged, the fixing portion 201 only needs to be rotated away from the limiting portion 102, so that the fixing portion 201 can be disengaged. At the same time, the extruding portion 202 can rotate in the same direction, so that the extruding portion 202 rotates through the adaptation space K and provides an extrusion force in at least the second direction to the pressed portion 101, so that the plug connected to the second connecting member 200 is lifted upward, thereby separating the plug from the socket, and improving the safety during the plugging and unplugging process.

[0088] The fourth situation is: Fig. 9As shown, the pressure-bearing portion 101 on the first connecting member 100 is an inclined plane with a certain angle. When the plug is inserted into the socket, the second connecting member 200 on the plug will engage with the first connecting member 100 on the socket. Specifically, the fixing portion 201 will pass through the connecting hole 103. In this embodiment, the guide surface M is arranged on the side wall of the connecting hole 103. When the fixing portion 201 passes through, it will flexibly cooperate with the guide surface M, so that the fixing portion 201 rotates and hooks the limiting portion 102 along the first direction. At this time, the extruding portion 202 will rotate together with the fixing portion 201, and through the provided adaptation space K, the extruding portion 202 can rotate in the adaptation space K without affecting the pressure-bearing portion 101. Therefore, after the fixing portion 201 hooks the limiting portion 102, a stable connection between the plug and the socket can be formed.

[0089] According to Fig. 9 In the implementation mode, when the plug needs to be unplugged, the fixing portion 201 only needs to be rotated to move it away from the limiting portion 102. At this time, the fixing portion 201 is released, and at the same time, the extruding portion 202 rotates in the same direction, so that the extruding portion 202 rotates through the adaptation space K and provides an extrusion force in at least the second direction to the pressed portion 101, so that the plug connected to the second connecting member 200 can be lifted upward, thereby separating the plug from the socket, and providing safety during the plugging and unplugging process.

[0090] Preferably, in the second embodiment, the second connecting member 200 can perform linear motion away from the limiting portion 102 relative to the first connecting member 100, and the pressure portion 101 has a tendency to gradually approach the second surface M-2 from a direction close to the connecting hole 103 to a direction away from the connecting hole 103; when the fixing portion 201 moves away from the limiting portion 102 through linear motion, the extrusion portion 202 can generate a force in the second direction on the pressure portion 101.

[0091] Preferably, a slot 202 a is formed between the fixing portion 201 and the extruding portion 202 , and the slot 202 a has an extruding surface 202 a - 1 matched with the pressed portion 101 .

[0092] A clamping groove 202 a is formed between the fixing portion 201 and the pressing portion 202 , and can be clamped between the pressed portion 101 and the limiting portion 102 on the first connecting member 100 .

[0093] In the present invention, the surface of the slot 202a opposite to the inner hook surface 201a is the extrusion surface 202a-1. When the fixing portion 201 moves away from the limiting portion 102 in a linear motion, the extrusion surface 202a-1 is provided with a slope surface that can cooperate with the pressure-bearing portion 101.

[0094] The extrusion surface 202a-1 is mainly used for when the fixing part 201 moves relatively away from the limiting part 102, the extrusion part 202 will move therewith, and there will be a surface on the extrusion part 202 as the extrusion surface 202a-1. During the movement, the extrusion surface 202a-1 will generate a force in at least the second direction on the pressed part 101, thereby achieving the release and providing assistance to enable the plug to move away from the socket.

[0095] Preferably, the second connecting member 200 further includes an operating portion 203 ; the operating portion 203 is connected to the extruding portion 202 , and the operating portion 203 is disposed on the other end of the extruding portion 202 relative to the fixing portion 201 .

[0096] The operating portion 203 is mainly provided so that when the fixing portion 201 needs to move relatively away from the limiting portion 102, that is, when the fixing portion 201 needs to rotate or move linearly, the staff can conveniently hold it for operation; and the operating portion 203 can be of any shape. The present invention takes the operating portion 203 as an example of a long rod, such as Figure 1~Figure 3 As shown, when it is necessary to rotate the fixing portion 201 away from the limiting portion 102, it is only necessary to rotate the operating portion 203 to make the fixing portion 201 relatively separate from the limiting portion 102; similarly, when it is necessary to make a relative linear motion between the fixing portion 201 and the limiting portion 102, the setting of the operating portion 203 can also facilitate the staff to pull it, and pulling the operating portion 203 will cause the fixing portion 201 to move along with it.

[0097] When the second connecting member 200 moves from the connecting hole 103 on the first connecting member 100 by linear motion, so that the inner hook surface 201a is attached to the limiting portion 102, there are two specific cases:

[0098] The first case is: Fig.14 As shown, by setting a slide groove 303 (the slide groove 303 can be set on the plug, and can also be set on a carrier connected to the plug), the slide groove 303 in the present invention is set on the protective cover 301 connected to the plug; the slide groove 303 is mainly set to enable the second connecting member 200 to move linearly in the slide groove 303, that is, the second connecting member 200 can move linearly relative to the first connecting member 100 and away from the limiting portion 102 (of course, the present invention does not exclude other settings that can allow the second connecting member 200 to move linearly relative to the first connecting member 100).

[0099] A slider 206 is provided on the extrusion portion 202 , and the slider 206 can slide in the slide groove 303 .

[0100] During the process of plugging the plug into the socket, Fig.14As shown, the fixing portion 201 passes through the connecting hole 103, and the slope surface on the pressed portion 101 corresponds to the pressing surface 202a-1, while the inner hook surface 201a does not fit with the limiting portion 102. In order to make the connection between the plug and the socket more secure and prevent loosening, the fixing portion 201 can be made of Fig.14 In the state shown, the second connecting member 200 is continued to be pushed, so that the fixing portion 201 moves toward the direction close to the limiting portion 102, and then the inner hook surface 201a will fit on the limiting portion 102, so that a tight connection between the plug and the socket can be achieved, so that the plug will not be easily loosened due to unexpected circumstances; it should be noted that there is a certain friction coefficient between the slide groove 303 and the slider 206. When the second connecting member 200 is pushed to a certain position, that is, the slider 206 moves to a certain position of the slide groove 303, due to the existing friction coefficient, it will not move easily unless the staff deliberately applies additional thrust (of course, the present invention does not exclude other settings in which the slider 206 can be fixed at any position of the slide groove 303).

[0101] According to Fig.14 In the implementation mode, when it is necessary to unplug the plug, it is only necessary to pull the second connecting member 200 so that the second connecting member 200 can move linearly away from the limiting portion 102 relative to the first connecting member 100. At this time, since the pressure-bearing portion 101 is provided with an inclined plane with a certain angle, the extrusion surface 202a-1 is provided as an inclined plane cooperating with the pressure-bearing portion 101. When the second connecting member 200 moves in a direction away from the limiting portion 102, the extrusion surface 202a-1 cooperates with the pressure-bearing portion 101, so that the extrusion surface 202a-1 will generate a force of at least the second direction on the pressure-bearing portion 101. While completing the separation of the fixing portion 201 from the limiting portion 102, an assisting force is provided to pull the plug upward, so that the socket and the plug are separated.

[0102] The second situation is: Fig.16 As shown, by setting a movable groove 301a (the movable groove 301a can be set on the plug, and can also be set on a carrier connected to the plug), the movable groove 301a in the present invention is set on the protective cover 301 connected to the plug, and a movable block 207 that can movably cooperate with the movable groove 301a is set on the side wall of the pressure-bearing part 101; in this case, the second connecting member 200 can slide in the connecting hole 103, and when the plug and the socket are not engaged, there is no direct connection relationship between the second connecting member 200 and the plug; and similarly, there is a certain friction coefficient between the second connecting member 200 and the connecting hole 103. When the staff does not apply additional force to the second connecting member 200, the second connecting member 200 can be relatively fixed somewhere in the connecting hole 103, and the second connecting member 200 can only be pulled when the staff applies a pulling force.

[0103] When the second connecting member 200 is Fig.16 When the plug is placed in the connecting hole 103, the pressure-bearing portion 101 is provided with an inclined plane with a certain angle, and the extrusion surface 202a-1 is provided with an inclined plane cooperating with the pressure-bearing portion 101. At this time, the pressure-bearing portion 101 is in contact with the extrusion surface 202a-1, and the inner hook surface 201a is not in contact with the limiting portion 102. Furthermore, after the plug is inserted into the socket, the edge of the protective cover 301 below the movable block 207 is shorter than the edge of the protective cover 301 above the movable block 207, so that the edge of the protective cover 301 below the movable block 207 is shorter than the edge of the protective cover 301 above the movable block 207 during the process of the plug being buckled into the socket. Unaffected, after the plug and the socket are fastened together, the edge of the protective cover 301 located above the movable block 207 extends and fits on the movable block 207; and then in this state, in order to make the connection between the plug and the socket tighter and prevent the plug from getting loose due to unexpected circumstances, which would hinder the equipment maintenance and debugging process, the second connecting member 200 can be pushed toward the direction close to the limiting portion 102, and then the inner hook surface 201a fits on the limiting portion 102, and the movable block 207 enters the movable groove 301a on the protective cover 301, so that the plug cannot be easily loosened during the equipment debugging process.

[0104] According to Fig.16 In the implementation mode, when the plug needs to be unplugged, it is only necessary to pull the second connecting member 200 so that the fixing portion 201 is away from the limiting portion 102 to achieve the unlocking effect. At the same time, the inclined plane on the pressure-bearing portion 101 cooperates with the inclined plane on the extrusion surface 202a-1, so that the second connecting member 200 will push the plug upward when it moves. That is, when the second connecting member 200 is moving, the movable block 207 disengages from the movable groove 301a, so that the pressure-bearing portion 101 and the extrusion surface 202a-1 cooperate with each other, so that the second connecting member 200 will move upward, and the movable block 207 lifts the part of the protective cover 301 extending outward from the top, thereby helping to lift the plug and achieving the effect of "assisting to remove", which is labor-saving and convenient, and provides a certain degree of safety protection.

[0105] In daily applications, the plug is inserted into the socket, especially when the plug needs to be repeatedly plugged in and out during use, it will easily become loose. If the fastening connection between the two is not strengthened, it is very likely that the electrical equipment will fail during operation due to looseness or poor contact between the plug and the socket. Even more, when the equipment needs to run for a long time or is in a special working environment, the loosening of the plug will cause the equipment to stop working or cause other problems; or there is no fastening connection between the plug and the socket, so when in use, the plug may fall off due to accidental collision or pulling, increasing the risk of loose electrical connection or short circuit. Therefore, the present invention provides a second connecting member 200, which cooperates with the limiting portion 102 through the inner hook surface 201a, so that the plug and the socket can be tightly connected, thereby improving safety and reducing the failure rate, while also avoiding the possibility of misoperation to a certain extent, thereby improving the electrical connection quality of the equipment, so that the plug and the socket will not be easily loosened.

[0106] When the plug and the socket need to be separated, the plug may often be pulled suddenly, causing severe impact or friction between the plug and the socket, thereby causing abnormal operation or failure of the device. However, through the arrangement of the present invention, when the fixing portion 201 moves relatively away from the limiting portion 102, the extrusion portion 202 generates at least one force in the second direction on the pressed portion 101, that is, the extrusion portion 202 can press one end of the socket and lift one end of the plug, so that the socket and the plug can be separated more smoothly, avoiding the loosening of the socket caused by a sudden pull of the plug, ensuring the installation and stability of the socket connection, reducing the wear or damage of the contact ends of the plug and the socket, and extending the service life of the device; not only that, by providing an additional second connecting member 200 to control the separation of the plug and the socket, accidental electric shock or other safety problems caused by improper operation can be avoided to a certain extent, and the staff of the present invention can use the operation The plug is plugged and unplugged by the part 203, which takes the safety of the staff into consideration and makes the plugging and unplugging process more controllable. For example, when the equipment is experiencing a circuit fault and short circuit, it is safer to a certain extent by toggling the operating part 203 than by directly unplugging the plug. In addition, the second connecting piece 200 provided in the present invention can achieve the effect of fastening the connection when the plug and the socket are plugged in, and when the plug and the socket are separated, one action can not only achieve the effect of loosening the fastening connection between the plug and the socket, but also achieve the function of assisting in pulling out the plug while realizing unlocking, which is more labor-saving. Compared with directly fastening the connection between the plug and the socket, and needing to loosen the connection lock before pulling out the plug when separating, the present invention can complete two actions simultaneously, which is more convenient. Especially in the case where the plug and the socket need to be frequently connected and disconnected, the second connecting piece 200 can save a lot of time and energy for the staff, and also greatly reduce the tedious complexity in the operation.

[0107] Example 3, reference Figure 6~Figure 17, which is the third embodiment of the present invention, and this embodiment is based on the previous embodiment, except that Figure 10~Figure 13 As shown, the second connecting member 200 can also pass through the edge of the first connecting member 100 and buckle on the limiting portion 102 by rotating, without the need to additionally set up the connecting hole 103. When the plug is inserted into the socket, the second connecting member 200 passes through the first connecting member 100 from the edge. Due to the action of the guide surface M, the second connecting member 200 is deflected, so that the inner hook surface 201a is attached to the limiting portion 102, and the first connecting member 100 and the second connecting member 200 are also locked; when unlocking is required, the fixing portion 201 can be moved away from the limiting portion 102, so as to achieve the effect of unlocking and assisting the plug to be removed at the same time. The specific movement process principle of this scheme can refer to the movement process principle of the first embodiment mentioned above, and will not be elaborated here.

[0108] In addition, the second connecting member 200 can also be buckled on the edge of the first connecting member 100 by linear movement, such as Fig.15 , Fig.17 As shown, there is no need to pass through the connecting hole 103, and the first connecting member 100 and the second connecting member 200 can be fastened by pushing the fixing portion 201 toward the limiting portion 102, so that the inner hook surface 201a is fitted on the limiting portion 102, that is, the locking between the plug and the socket is achieved; similarly, when it is necessary to unplug the plug, the fixing portion 201 is pulled outward to make the fixing portion 201 away from the limiting portion 102, so that under the action of the inclined plane, unlocking is achieved while achieving the effect of assisting the removal of the plug. The specific movement process principle of this scheme can refer to the movement process principle of the second embodiment mentioned above, and will not be elaborated here.

[0109] Example 4, reference Figure 1 to Figure 17 , which is the fourth embodiment of the present invention, and this embodiment provides a connector mechanism, a plug 300, a second connector 200 connected to the plug 300; and a socket 400, a first connector 100 connected to the socket 400; the plug 300 is fixed on the socket 400 through the connection between the second connector 200 and the first connector 100.

[0110] Preferably, a mounting portion 204 is further provided between the operating portion 203 and the pressing portion 202 of the second connecting member 200 ; the second connecting member 200 is fixed to the plug 300 via the mounting portion 204 .

[0111] like Figure 1 As shown, the extrusion portion 202 is movably connected to the mounting portion 204. The mounting portion 204 can be of any shape. The mounting portion 204 is actually provided to form a connection relationship between the second connecting member 200 and the plug. The mounting portion 204 can enable the extrusion portion 202 to rotate relative to the plug.

[0112] Preferably, the second connecting member 200 further includes an elastic member 205 disposed on the mounting portion 204 ; the elastic member 205 can enable the extruding portion 202 to generate a movement trend in the first direction or in the extending direction of the fixing portion 201 .

[0113] The elastic member 205 is a device that can undergo elastic deformation. In the present invention, the elastic member 205 is preferably a torsion spring. One end of the elastic member 205 is connected to the second connecting member 200, and the other end is connected to the plug (or a carrier connected to the plug, such as the protective cover 301). The actual purpose of setting the elastic member 205 is that when the second connecting member 200 can rotate relative to the first connecting member 100, when the fixing portion 201 deflects through the connecting hole 103, under the action of the elastic member 205, the inner hook surface 201a can be attached to the limiting portion 102; and when the plug is separated from the socket, the elastic member 205 can also reset the second connecting member 200.

[0114] Preferably, the plug 300 includes a protective cover 301 and a cable tie opening 302 disposed on the protective cover 301 ; the second connector 200 is fixed to the edge of the protective cover 301 of the plug 300 through the mounting portion 204 .

[0115] The protective cover 301 is arranged on the outside of the plug, which can play a role in dust and water proofing the plug during daily use; a wire harness opening 302 is arranged on the protective cover 301, and when the wires on the plug are connected, the wires can be combed out from the wire harness opening 302, making the overall wiring more neat and orderly, and improving the aesthetics.

[0116] In summary, when the operating part 203 is bent so that the fixing part 201 is away from the limiting part 102, the extrusion part 202 will rotate in the same direction and be squeezed by the extrusion part 202 to generate a force in the second direction, so that the first connecting member 100 and the second connecting member 200 are separated, thereby separating the plug 300 and the socket 400. After the plugging and unplugging action is completed, the extrusion part 202 can be restored to its initial state under the action of the elastic member 205.

[0117] Example 5, reference Figure 1 to Figure 19 , which is the fifth embodiment of the present invention, and this embodiment provides a test plug wiring system, wherein the plug 300 is a single-loop test plug or a multi-loop test plug; the socket 400 is connected to the device to be tested, and the plug 300 is connected to a detection device that can be used to detect the device to be tested.

[0118] In summary, in practical applications, the plug 300 in the present invention can be a single-loop test plug or a multi-loop test plug. The plug 300 is connected to a detection instrument, and the socket 400 is connected to the corresponding device to be tested. When it is necessary to detect the continuity of the internal electrical circuit of the device to be tested, it is only necessary to connect the plug 300 to the socket 400.

[0119] Example 6, reference Figure 1 to Figure 21 , which is the sixth embodiment of the present invention, and this embodiment provides the specific design dimensions of the first case in the first implementation mode, that is, Figure 6 Design for application dimensions shown.

[0120] Table 1 Dimensional design table of the first case in the first implementation method

[0121] ,

[0122] like Fig. 20 As shown in Table 1, the second connectors 200 are symmetrically arranged on both sides of the protective cover 301, and the distance from the rotation center of one second connector 200 to the rotation center of another second connector 200 is set to Z. Considering that the plug on the 24-pin connector has a standard length, the Z dimension cannot be too short, and if the Z dimension is too long, it will waste space, so the value range of Z is 153mm~165mm.

[0123] like Fig.21 As shown in Table 1, the distance from the rotation center point of the extrusion portion 202 to the extended end of the extrusion portion 202 is defined as X, and the value range of X is preferably 9 mm to 14 mm. If it is less than 9 mm, the extrusion portion 202 will be too short to apply at least a second direction force to the pressed portion 101 during rotation. If X exceeds 14 mm, the overall second connecting member 200 will occupy too much space.

[0124] like Fig.21 As shown in Table 1, the distance from the rotation center point of the extrusion part 202 to the extrusion surface 202a-1 is defined as Y, and the value range of Y is preferably 3.5mm~10mm.

[0125] When the first connecting member 100 is disengaged from the second connecting member 200, the angle at which the fixing portion 201 or the extruding portion 202 rotates is defined as an action angle β. Considering the pulling stroke of the extruding portion 202 and whether it can provide a force in the second direction to disengage the plug 300, the value range of β is preferably 42°~76°.
