Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a plug and a connector. Background Art

[0002] Connectors are increasingly being used in the market and are indispensable in signal transmission technology. When a system using a connector is used in an environment subject to vibration or shaking, the plug may be accidentally pulled by external forces (such as wire tension), which can cause it to loosen or shift sideways from the socket, thereby disconnecting the contact between the clip and the pin inside the plug, causing signal interruption or error, such as signal "1" changing to signal "0." This can cause abnormal operation or interruption of the entire electrical system, affecting the stability of the entire system, especially when there are multiple connectors in the system, where the failure rate will be even higher. The above defects are particularly prominent when the connector uses a guide rail terminal block and a guide rail terminal block plug. Utility Model Content

[0003] To overcome the shortcomings of the prior art, the present invention provides a plug that, by providing an auxiliary clamping structure, enables the elastic clamping member in the plug, with the aid of the auxiliary clamping structure, to significantly increase its clamping force on the pins in the socket, ensuring electrical contact and electrical conductivity between the two, and having better anti-loosening capabilities. The present invention also provides a connector.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A plug is used for plugging into a socket and electrically connecting to pins in the socket, comprising: a plug housing;

[0006] an elastic clamping member disposed within the plug housing and having conductive properties, comprising an elastic clamping portion having a clamping opening for inserting a pin of the socket, the elastic clamping portion being capable of deforming outward to expand the clamping opening, and having a tendency to return inward to its original shape when deformed outward;

[0007] and an auxiliary clamping structure disposed within the plug housing, comprising an auxiliary clamping portion having an auxiliary opening, the auxiliary clamping portion being deformable outwardly to expand the auxiliary opening, and having a tendency to return inwardly to its original shape when deformed outwardly;

[0008] When the elastic clamping portion is located in the auxiliary opening and the pin in the socket is inserted into the clamping opening, the elastic clamping portion acts on the auxiliary clamping portion to deform the auxiliary clamping portion outward.

[0009] With the above structure, when a user inserts the plug into a socket, the pin in the socket acts on the elastic clamping portion, causing the elastic holding portion to deform outward, and the clamping opening to expand to facilitate the insertion of the pin into the clamping opening. At this time, the elastic clamping portion has a tendency to return to its original shape inward to act on the pin, so that the clamping opening can be in close contact with the pin to achieve good electrical contact and electrical conductivity between the two.

[0010] At the same time, when the elastic clamping portion is deformed outward, it will act on the auxiliary clamping portion and enable the auxiliary clamping portion to deform outward. At this time, the auxiliary clamping portion has a tendency to restore its original shape inward to act on the elastic persistence portion, so that the clamping force of the clamping mouth of the elastic clamping member on the pin is increased, further ensuring the electrical contact and electrical conductivity between the two, and having better anti-loosening ability.

[0011] Furthermore, the elastic clamping portion includes a first clamping portion and a second clamping portion that are arranged opposite to each other, and the clamping opening is formed between the first clamping portion and the second clamping portion; the first clamping portion is movable relative to the second clamping portion and has a tendency to move toward the second clamping portion when it is away from the second clamping portion, and / or the second clamping portion is movable relative to the first clamping portion and has a tendency to move toward the first clamping portion when it is away from the first clamping portion.

[0012] The above structure makes the structure of the elastic clamping part more reasonable, so that the elastic clamping part can be deformed outward to expand the clamping opening and has the ability to return to its original shape inward when deformed outward; specifically, the first clamping part can move relative to the second clamping part, and the second clamping part can also move relative to the first clamping part.

[0013] Furthermore, the auxiliary clamping part includes a first clamping part and a second clamping part which are arranged opposite to each other, the first clamping part is located on a side of the first clamping part away from the second clamping part, the second clamping part is located on a side of the second clamping part away from the first clamping part, and the auxiliary opening is formed between the first clamping part and the second clamping part; when the first clamping part is movable relative to the second clamping part, the first clamping part is movable relative to the second clamping part and has a tendency to move toward the second clamping part when it is away from the second clamping part, and when the second clamping part is movable relative to the first clamping part, the second clamping part is movable relative to the first clamping part and has a tendency to move toward the first clamping part when it is away from the first clamping part.

[0014] The above structure makes the structure of the auxiliary clamping portion more reasonable, and enables the auxiliary clamping portion to deform outward to expand the auxiliary opening and to have the tendency to return inward to its original shape when deformed outward.

[0015] Further, the elastic clamping member includes an elastic clamping connection portion, a first elastic clamping force arm, and a second elastic clamping force arm, one end of the first elastic clamping force arm is connected to one side of the elastic clamping connection portion, and the other end is formed as a first clamping force arm movable end, one end of the second elastic clamping force arm is connected to the other side of the elastic clamping connection portion, and the other end is formed as a second clamping force arm movable end, the first elastic clamping force arm and the second elastic clamping force arm are respectively formed as the first clamping portion and the second clamping portion, and the clamping opening is formed between the movable end of the first clamping force arm and the movable end of the second clamping force arm.

[0016] The above structure makes the structure of the elastic clamp more reasonable, and the function of the elastic clamp, that is, the elastic deformation ability of the first clamping part and the second clamping part, can be achieved with a simple structure; specifically, the elastic clamp adopts an integrated structure.

[0017] Furthermore, the auxiliary clamping structure includes an auxiliary clamping connection part, a first auxiliary clamping force arm, and a second auxiliary clamping force arm, one end of the first auxiliary clamping force arm is connected to one side of the auxiliary clamping connection part, and the other end is formed as a first clamping force arm movable end, one end of the second auxiliary clamping force arm is connected to the other side of the auxiliary clamping connection part, and the other end is formed as a second clamping force arm movable end, the first auxiliary clamping force arm and the second auxiliary clamping force arm are respectively formed as the first clamping part and the second clamping part, the first clamping force arm movable end and the second clamping force arm movable end extend toward the side of the elastic clamping member groove to form a first auxiliary action part and a second auxiliary action part, respectively, and the auxiliary mouth is formed between the first auxiliary action part and the second auxiliary action part.

[0018] The above-mentioned structure makes the structure of the auxiliary clamping structure more reasonable, and the function of the auxiliary clamping structure, that is, the deformation ability of the first clamping part and the second clamping part, can be achieved by adopting a simple structure; and the first auxiliary action part and the second auxiliary action part provided with a protrusion can better cooperate with the elastic clamping part and act on the elastic clamping part; specifically, the auxiliary clamping structure adopts an integrated structure.

[0019] Furthermore, the first auxiliary clamping arm and the second auxiliary clamping arm are sheet-like structures, and the first auxiliary clamping arm has a certain width in the moving direction of the first clamping part, and the second auxiliary clamping arm has a certain width in the moving direction of the second clamping part, that is, the auxiliary clamping structure is formed as an 'n'-shaped planar structure spring sheet.

[0020] By adopting the above structure, the first auxiliary clamping force arm and the second auxiliary clamping force arm can provide a stronger clamping force when they undergo a smaller deformation, so that the auxiliary clamping structure can fit into a smaller space.

[0021] Furthermore, the width of the first auxiliary clamping arm gradually decreases along the direction from the end where the first auxiliary clamping arm is connected to the auxiliary clamping connection part to the movable end of the first clamping arm, and the width of the second auxiliary clamping arm gradually decreases along the direction from the end where the second auxiliary clamping arm is connected to the auxiliary clamping connection part to the movable end of the second clamping arm.

[0022] With the above structure, the first clamping force arm and the second clamping force arm can be deformed more easily under the action of the elastic clamping part.

[0023] Furthermore, the movable end of the first clamping arm is recessed toward one side of the movable end of the second clamping arm, away from the movable end of the second clamping arm, to form a first notch; the movable end of the second clamping arm is recessed toward one side of the movable end of the first clamping arm, away from the movable end of the first clamping arm, to form a second notch.

[0024] With the above structure, the setting of the first notch and the setting of the second notch reduce the widths of the first auxiliary action part and the second auxiliary action part accordingly, so as to form an avoidance space for the elastic clamping part, that is, to increase the opening size of the auxiliary port so that the elastic clamping part is located in the auxiliary port.

[0025] Furthermore, in the auxiliary clamping structure, at least the first auxiliary clamping arm and the second auxiliary clamping arm are made of spring steel.

[0026] The above structure makes the auxiliary clamping structure more reasonable, so that the first auxiliary clamping arm and the second auxiliary clamping arm can provide a stronger clamping force when they undergo a smaller deformation, so that the auxiliary clamping structure can adapt to a smaller space.

[0027] Furthermore, the plug housing is provided with a plug installation cavity for accommodating the elastic clamping member;

[0028] The elastic clamping member is arranged in the plug installation cavity, and the auxiliary clamping structure is arranged in the plug installation cavity and is located behind the elastic clamping portion.

[0029] The above structure makes the plug housing structure more reasonable, and the auxiliary clamping structure and the elastic clamping member are reasonably positioned, thereby achieving stable cooperation between the auxiliary clamping structure and the elastic clamping member without occupying too much additional space, which is convenient for users' actual use.

[0030] Furthermore, the plug installation cavity protrusion is provided with a clamping member positioning column, and correspondingly, the elastic clamping member is provided with a clamping member positioning hole matching the clamping member positioning column; the plug installation cavity protrusion is provided with a clamping structure positioning column, and correspondingly, the auxiliary clamping structure is provided with a clamping structure positioning hole matching the clamping structure positioning column.

[0031] With the above structure, the clamping member positioning column and the clamping member positioning hole cooperate to realize the positioning and installation of the elastic clamping member in the plug installation cavity; the clamping structure positioning column and the clamping structure positioning hole cooperate to realize the positioning and installation of the auxiliary clamping structure in the plug installation cavity; specifically, the clamping member positioning hole is arranged on the elastic clamping connection part; the auxiliary clamping connection part, the first auxiliary clamping force arm and the second auxiliary clamping force arm together form the clamping structure positioning hole.

[0032] Furthermore, the plug installation cavity protrusion is provided with a limiting protrusion, the clamping member positioning column is located above the limiting protrusion, the elastic clamping member includes an elastic clamping connection portion connected to the elastic clamping portion, the clamping member positioning hole is provided on the elastic clamping connection portion, and the distance from the clamping member positioning hole to the lower edge of the elastic clamping connection portion matches the distance from the clamping member positioning column to the upper end surface of the limiting protrusion;

[0033] The clamping structure positioning column is located below the limiting protrusion, and the distance from the clamping structure positioning hole to the upper edge of the auxiliary clamping structure matches the distance from the clamping structure positioning column to the lower end surface of the limiting protrusion.

[0034] With the above structure, when the elastic clamping member is installed in the plug installation cavity, the clamping member positioning hole cooperates with the clamping member positioning column, and the lower edge of the elastic clamping connection portion rests on the upper end surface of the limiting protrusion, making the installation of the elastic clamping member more stable and preventing it from rotating.

[0035] When the auxiliary clamping structure is installed in the plug installation cavity, the clamping structure positioning hole cooperates with the clamping structure positioning column, and the upper edge of the auxiliary clamping structure rests on the lower end surface of the limiting protrusion, making the installation of the auxiliary clamping structure more stable and avoiding rotation.

[0036] Furthermore, the plug housing is provided with a pin entry hole for the pin of the socket to enter at a position opposite to the clamping opening.

[0037] The above structure makes the plug housing structure more reasonable.

[0038] A connector comprises a socket and the above-mentioned plug, wherein the socket comprises a socket housing and a conductive pin, wherein the pin is arranged in the socket housing.

[0039] With the above structure, when the plug is plugged into the socket, the elastic clamping member in the plug, with the assistance of the auxiliary clamping structure, can greatly increase its clamping force on the pins in the socket, thereby ensuring electrical contact and electrical conductivity between the two and having better anti-loosening capability.

[0040] Furthermore, the socket housing is provided with a plug insertion cavity for inserting the plug, and at least one end of the pin is located in the plug insertion cavity;

[0041] The portion of the plug housing for inserting into the plug insertion cavity is formed as a plug housing insertion portion, a locking protrusion is provided on a first plug outer side wall of the plug housing insertion portion, and a locking groove is correspondingly provided on a first insertion cavity inner wall opposite to the first plug outer side wall in the plug insertion cavity, and when the plug housing insertion portion is fully inserted into the plug insertion cavity, the locking protrusion is located in the locking groove.

[0042] With the above structure, when the plug housing insertion portion is fully inserted into the plug insertion cavity, the locking protrusion is located in the locking slot to achieve locking, which can greatly improve the anti-loosening capability of the plug.

[0043] Furthermore, along the direction in which the plug housing insertion portion is inserted into the plug insertion cavity, the end surface of the locking protrusion that first contacts the inner wall of the first insertion cavity and / or the side of the inner wall of the first insertion cavity that first contacts the locking protrusion are provided with a first guide surface for guiding the locking protrusion into the locking slot;

[0044] Along the direction of pulling the plug housing out of the plug insertion cavity, the end surface of the locking protrusion that first contacts the locking groove and / or the side of the locking groove that first contacts the locking protrusion are provided with a second guide surface for guiding the locking protrusion to disengage from the locking groove;

[0045] Specifically, the first guide surface and the second guide surface are inclined surfaces or arc-shaped surfaces.

[0046] The above structure makes the structural arrangement of the plug and the socket more reasonable. The arrangement of the first guide surface makes it easier for the user to insert the plug insertion portion into the plug insertion cavity; the arrangement of the second guide surface makes it easier for the user to unlock the locking protrusion and the locking slot when pulling the plug insertion portion out of the plug insertion cavity.

[0047] Furthermore, along the direction of the plug shell insertion part being inserted into the plug insertion cavity, a locking tongue structure is provided at the end of the plug shell insertion part that first enters the plug insertion cavity, and a lock hole slot structure for inserting the locking tongue structure is provided on the side of the plug insertion cavity opposite to its opening, and when the plug shell insertion part is fully inserted into the plug insertion cavity, the locking tongue structure is inserted into the lock hole slot structure.

[0048] With the above structure, when the plug housing insertion portion is fully inserted into the plug insertion cavity, the locking tongue structure is inserted into the locking hole slot structure, and the two cooperate to lock and prevent the plug from moving or rotating sideways, thereby ensuring a stable and reliable connection between the plug and the socket;

[0049] The above structure is particularly suitable for the case where the socket adopts a semi-open structure similar to a guide rail terminal block.

[0050] Furthermore, the locking tongue structure includes a locking tongue connecting portion, and a first locking tongue block and a second locking tongue block arranged on both sides of the locking tongue connecting portion, and the first locking tongue block and the second locking tongue block are located on both sides of the clamping port; correspondingly, the lock hole slot structure includes a lock hole connecting slot matching the locking tongue connecting portion, and a first lock hole slot and a second lock hole slot arranged on both sides of the lock hole connecting portion and matching the first lock tongue block and the second lock tongue block respectively, and the first lock hole slot and the second lock hole slot are located on both sides of the pin, and when the plug shell insertion portion is fully inserted into the plug insertion cavity, the bottom surface of the lock hole connecting slot is opposite to the bottom surface of the locking tongue connecting portion.

[0051] The above structure makes the structural arrangement of the lock tongue structure and the lock hole slot structure more reasonable, ensuring stable and reliable locking cooperation between the two.

[0052] Furthermore, the front sides of the first lock hole slot and the second lock hole slot are respectively provided with a first communication port and a second communication port identical thereto.

[0053] With the above structure, the provision of the first communication port and the second communication port enables the user to observe whether the first locking tongue block and the second locking tongue block are inserted into the first lock hole slot and the second lock hole slot when inserting the plug.

[0054] Furthermore, a limiting guide portion is provided on the outer side wall of the second plug of the plug shell insertion portion, and a limiting guide groove matching the limiting guide portion is correspondingly provided on the inner wall of the second insertion cavity in the plug insertion cavity opposite to the outer side wall of the second plug, and the limiting guide groove extends along the insertion direction of the plug shell insertion portion.

[0055] With the above structure, the cooperation between the position limiting guide portion and the position limiting guide groove can play a guiding role during the process of inserting the plug into the socket, and has a certain position limiting effect.

[0056] Furthermore, the limiting guide portion includes a limiting guide block and a first limiting guide connecting portion for connecting the limiting guide block and the outer side wall of the second plug; correspondingly, the limiting guide groove includes a first limiting guide groove matching the limiting guide block, and a second limiting guide groove connecting the first limiting guide groove and the plug insertion cavity, and the second limiting guide groove matches the first limiting guide connecting portion;

[0057] The thickness of the position-limiting guide block is greater than the thickness of the first position-limiting guide connecting portion. Correspondingly, the width of the first position-limiting guide groove is greater than the width of the second position-limiting guide groove.

[0058] With the above structure, the structures of the position-limiting guide portion and the position-limiting guide groove are more reasonable, and the two can cooperate better to achieve better guidance and position limiting.

[0059] Furthermore, the outer side wall of the second plug and the outer side wall of the first plug are the same side wall of the plug shell insertion part, and correspondingly, the inner wall of the second insertion cavity and the inner wall of the first insertion cavity are the same inner wall of the plug insertion cavity; along the direction of the plug shell insertion part being inserted into the plug insertion cavity, the locking protrusion is located in front of the limit guide part, and the locking slot is located in front of the limit guide slot.

[0060] Along the direction of the plug shell insertion portion being inserted into the plug insertion cavity, the locking protrusion is located in front of the limiting guide portion, and the locking slot is located in front of the limiting guide slot. It can be understood that, in the process of the plug shell insertion portion being inserted into the plug insertion cavity, the locking protrusion enters the plug insertion cavity before the limiting guide portion, and the plug shell insertion portion first passes through the limiting guide slot and then passes through the locking slot.

[0061] The above structure makes the structure of the plug and the socket more reasonable; during installation, the locking protrusion first passes through the limiting guide groove, and then enters the locking slot after being retracted and tightly pressed, which greatly reduces the distance that the locking protrusion needs to move after being squeezed, making it easier to insert the plug during actual use.

[0062] Furthermore, the portion of the plug shell that is not inserted into the plug insertion cavity is formed as a plug shell body, and the side of the plug shell body on the same side as the outer side wall of the second plug protrudes from the outer side wall of the second plug, and the limiting guide portion includes a second limiting guide connecting portion, and the two ends of the second limiting guide connecting portion are respectively connected to the limiting guide block and the side of the plug shell body facing the plug shell insertion portion.

[0063] With the above structure, the structural arrangement of the plug housing is more reasonable, and the arrangement of the second position-limiting guide connecting portion makes the arrangement of the position-limiting guide block more stable.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0083] The following describes the technical solutions provided by various embodiments of the present application in conjunction with the accompanying drawings.

[0084] See Figures 1 to 3 , the utility model provides a plug 1, which is used to be plugged into a socket 2 and electrically connected to a pin 201 in the socket 2, comprising: a plug housing 101;

[0085] The elastic clamping member 102 is disposed within the plug housing 101 and has conductive properties. The elastic clamping member 1021 has a clamping opening 1022 for inserting the pin 201 of the socket 2. The elastic clamping member 1021 can deform outward to expand the clamping opening 1022, and the elastic clamping member 1021 has a tendency to return inward to its original shape after deforming outward.

[0086] and an auxiliary clamping structure 103 disposed within the plug housing 101, comprising an auxiliary clamping portion 1031 having an auxiliary opening 1032. The auxiliary clamping portion 1031 is capable of deforming outward to expand the auxiliary opening 1032, and the auxiliary clamping portion 1031 has a tendency to return inward to its original shape when deformed outward.

[0087] When the elastic clamping portion 1021 is located in the auxiliary opening 1032 and the pin 201 in the socket 2 is inserted into the clamping opening 1022 , the elastic clamping portion 1021 acts on the auxiliary clamping portion 1031 to deform the auxiliary clamping portion 1031 outward.

[0088] With the above structure, when the user inserts the plug 1 into the socket 2, the pin 201 in the socket 2 acts on the elastic clamping portion 1021, causing the elastic holding portion to deform outward, and the clamping opening 1022 to expand to facilitate the insertion of the pin 201 into the clamping opening 1022. At this time, the elastic clamping portion 1021 has a tendency to return to its original shape inward to act on the pin 201, so that the clamping opening 1022 can be in close contact with the pin 201 to achieve good electrical contact and electrical conductivity between the two.

[0089] At the same time, when the elastic clamping portion 1021 is deformed outward, it will act on the auxiliary clamping portion 1031 and enable the auxiliary clamping portion 1031 to deform outward. At this time, the auxiliary clamping portion 1031 has a tendency to restore its original shape inward to act on the elastic persistence portion, so that the clamping force of the clamping port 1022 of the elastic clamping member 102 on the pin 201 is increased, further ensuring the electrical contact and electrical conductivity between the two, and having better anti-loosening ability.

[0090] Furthermore, the elastic clamping portion 1021 includes a first clamping portion 1021a and a second clamping portion 1021b that are arranged opposite to each other, and the clamping mouth 1022 is formed between the first clamping portion 1021a and the second clamping portion 1021b; the first clamping portion 1021a is movable relative to the second clamping portion 1021b and has a tendency to move toward the second clamping portion 1021b when it is away from the second clamping portion 1021b, and / or the second clamping portion 1021b is movable relative to the first clamping portion 1021a and has a tendency to move toward the first clamping portion 1021a when it is away from the first clamping portion 1021a.

[0091] The above structure makes the structure of the elastic clamping part 1021 more reasonable, so that the elastic clamping part 1021 can be deformed outward to expand the clamping mouth 1022 and has the ability to restore its original shape inward when deformed outward; specifically, the first clamping part 1021a can move relative to the second clamping part 1021b, and the second clamping part 1021b can also move relative to the first clamping part 1021a.

[0092] Furthermore, the auxiliary clamping portion 1031 includes a first clamping portion 1031a and a second clamping portion 1031b that are arranged opposite to each other, the first clamping portion 1031a is located on a side of the first clamping portion 1021a away from the second clamping portion 1021b, the second clamping portion 1031b is located on a side of the second clamping portion 1021b away from the first clamping portion 1021a, and the auxiliary opening 1032 is formed between the first clamping portion 1031a and the second clamping portion 1031b; When the second clamping part 1021b is movable, the first clamping part 1031a can move relative to the second clamping part 1031b and has a tendency to move toward the side of the second clamping part 1031b when it is away from the second clamping part 1031b. When the second clamping part 1021b is movable relative to the first clamping part 1021a, the second clamping part 1031b can move relative to the first clamping part 1031a and has a tendency to move toward the side of the first clamping part 1031a when it is away from the first clamping part 1031a.

[0093] The above structure makes the auxiliary clamping portion 1031 more rational in structure, and enables the auxiliary clamping portion 1031 to deform outward to expand the auxiliary opening 1032 and to have the ability to return to its original shape inward when deformed outward.

[0094] Furthermore, the elastic clamping member 102 includes an elastic clamping connection portion 1023, a first elastic clamping force arm 1024, and a second elastic clamping force arm 1025, one end of the first elastic clamping force arm 1024 is connected to one side of the elastic clamping connection portion 1023, and the other end is formed as a first clamping force arm movable end 1024a, one end of the second elastic clamping force arm 1025 is connected to the other side of the elastic clamping connection portion 1023, and the other end is formed as a second clamping force arm movable end 1025a, the first elastic clamping force arm 1024 and the second elastic clamping force arm 1025 are respectively formed as the first clamping portion 1021a and the second clamping portion 1021b, and the clamping opening 1022 is formed between the first clamping force arm movable end 1024a and the second clamping force arm movable end 1025a.

[0095] The above structure makes the structure of the elastic clamping member 102 more reasonable, and the function of the elastic clamping member 102, that is, the elastic deformation ability of the first clamping part 1021a and the second clamping part 1021b, can be achieved by adopting a simple structure; specifically, the elastic clamping member 102 adopts an integrated structure.

[0096] Furthermore, the auxiliary clamping structure 103 includes an auxiliary clamping connection portion 1033, a first auxiliary clamping force arm 1034, and a second auxiliary clamping force arm 1035, wherein one end of the first auxiliary clamping force arm 1034 is connected to one side of the auxiliary clamping connection portion 1033, and the other end is formed as a first clamping force arm movable end 1034a, and one end of the second auxiliary clamping force arm 1035 is connected to the other side of the auxiliary clamping connection portion 1033, and the other end is formed as a second clamping force arm movable end 1035a. An auxiliary clamping force arm 1034 and the second auxiliary clamping force arm 1035 are respectively formed as the first clamping part 1031a and the second clamping part 1031b, and the movable end 1034a of the first clamping force arm and the movable end 1035a of the second clamping force arm extend toward the groove side of the elastic clamping member 102 to form the first auxiliary action part 1034b and the second auxiliary action part 1035b, respectively, and the auxiliary mouth 1032 is formed between the first auxiliary action part 1034b and the second auxiliary action part 1035b.

[0097] The above-mentioned structure makes the structure of the auxiliary clamping structure 103 more reasonable, and the function of the auxiliary clamping structure 103, that is, the deformation ability of the first clamping part 1031a and the second clamping part 1031b, can be achieved by adopting a simple structure; and the first auxiliary action part 1034b and the second auxiliary action part 1035b provided with a protrusion can better cooperate with the elastic clamping part 102 and act on the elastic clamping part 102; specifically, the auxiliary clamping structure 103 adopts an integrated structure.

[0098] Furthermore, the first auxiliary clamping arm 1034 and the second auxiliary clamping arm 1035 are sheet-like structures, and the first auxiliary clamping arm 1034 has a certain width in the moving direction of the first clamping part 1031a, and the second auxiliary clamping arm 1035 has a certain width in the moving direction of the second clamping part 1031b, that is, the auxiliary clamping structure 103 is formed as an 'n'-shaped planar structure spring sheet.

[0099] With the above structure, the first auxiliary clamping arm 1034 and the second auxiliary clamping arm 1035 can provide a stronger clamping force even when they undergo a slight deformation, so that the auxiliary clamping structure 103 can fit into a smaller space.

[0100] Furthermore, the width of the first auxiliary clamping arm 1034 gradually decreases along the direction from the end where the first auxiliary clamping arm 1034 is connected to the auxiliary clamping connection part 1033 to the movable end 1034a of the first clamping arm, and the width of the second auxiliary clamping arm 1035 gradually decreases along the direction from the end where the second auxiliary clamping arm 1035 is connected to the auxiliary clamping connection part 1033 to the movable end 1035a of the second clamping arm.

[0102] Furthermore, the first clamping arm movable end 1034a is recessed toward one side of the second clamping arm movable end 1035a away from the second clamping arm movable end 1035a to form a first notch 1034c, and the second clamping arm movable end 1035a is recessed toward one side of the first clamping arm movable end 1034a away from the first clamping arm movable end 1034a to form a second notch 1035c.

[0103] With the above structure, the setting of the first notch 1034c and the setting of the second notch 1035c cause the widths of the first auxiliary action portion 1034b and the second auxiliary action portion 1035b to be reduced accordingly, so as to form an avoidance space for the elastic clamping portion 1021, that is, to increase the opening size of the auxiliary port 1032 so that the elastic clamping portion 1021 is located in the auxiliary port 1032.

[0104] Furthermore, in the auxiliary clamping structure 103 , at least the first auxiliary clamping arm 1034 and the second auxiliary clamping arm 1035 are made of spring steel.

[0105] The above structure makes the auxiliary clamping structure 103 more reasonable, so that the first auxiliary clamping force arm 1034 and the second auxiliary clamping force arm 1035 can provide a stronger clamping force when they undergo a smaller deformation, so that the auxiliary clamping structure 103 can adapt to a smaller space.

[0106] Furthermore, the plug housing 101 is provided with a plug installation cavity 1011 for accommodating the elastic clamping member 102;

[0107] The elastic clamping member 102 is disposed in the plug installation cavity 1011 , and the auxiliary clamping structure 103 is disposed in the plug installation cavity 1011 and is located behind the elastic clamping portion 1021 .

[0108] The above structure makes the structure of the plug housing 101 more reasonable, and the auxiliary clamping structure 103 and the elastic clamping member 102 are reasonably positioned, achieving stable cooperation between the auxiliary clamping structure 103 and the elastic clamping member 102 without taking up too much additional space, which is convenient for users' actual use.

[0109] Furthermore, the protrusion of the plug installation cavity 1011 is provided with a clamping member positioning column 1012, and correspondingly, the elastic clamping member 102 is provided with a clamping member positioning hole 1026 matching the clamping member positioning column 1012; the protrusion of the plug installation cavity 1011 is provided with a clamping structure positioning column 1013, and correspondingly, the auxiliary clamping structure 103 is provided with a clamping structure positioning hole 1036 matching the clamping structure positioning column 1013.

[0110] By adopting the above structure, the clamping member positioning column 1012 and the clamping member positioning hole 1026 cooperate to realize the positioning and installation of the elastic clamping member 102 in the plug installation cavity 1011; the clamping structure positioning column 1013 and the clamping structure positioning hole 1036 cooperate to realize the positioning and installation of the auxiliary clamping structure 103 in the plug installation cavity 1011; specifically, the clamping member positioning hole 1026 is arranged on the elastic clamping connection part 1023; the auxiliary clamping connection part 1033, the first auxiliary clamping force arm 1034 and the second auxiliary clamping force arm 1035 enclose to form the clamping structure positioning hole 1036.

[0111] Furthermore, the plug installation cavity 1011 is convexly provided with a limiting protrusion 1014, the clamping member positioning column 1012 is located above the limiting protrusion 1014, the elastic clamping member 102 includes an elastic clamping connection portion 1023 connected to the elastic clamping portion 1021, and the clamping member positioning hole 1026 is provided on the elastic clamping connection portion 1023, and the distance from the clamping member positioning hole 1026 to the lower edge of the elastic clamping connection portion 1023 matches the distance from the clamping member positioning column 1012 to the upper end surface of the limiting protrusion 1014;

[0112] The clamping structure positioning column 1013 is located below the limiting protrusion 1014 , and the distance from the clamping structure positioning hole 1036 to the upper edge of the auxiliary clamping structure 103 matches the distance from the clamping structure positioning column 1013 to the lower end surface of the limiting protrusion 1014 .

[0113] With the above structure, when the elastic clamping member 102 is installed in the plug installation cavity 1011, the clamping member positioning hole 1026 cooperates with the clamping member positioning column 1012, and the lower edge of the elastic clamping connection portion 1023 rests on the upper end surface of the limiting protrusion 1014, making the installation of the elastic clamping member 102 more stable and preventing it from rotating.

[0114] When the auxiliary clamping structure 103 is installed in the plug installation cavity 1011, the clamping structure positioning hole 1036 cooperates with the clamping structure positioning column 1013, and the upper edge of the auxiliary clamping structure 103 rests on the lower end face of the limiting protrusion 1014, making the installation of the auxiliary clamping structure 103 more stable and preventing it from rotating.

[0115] Furthermore, the plug housing 101 is provided with a pin entry hole 1015 at a position opposite to the clamping opening 1022 for the pin 201 of the socket 2 to enter.

[0116] The above structure makes the structure of the plug housing 101 more reasonable.

[0117] See Figures 1 to 6 A connector includes a socket 2 and the above-mentioned plug 1, wherein the socket 2 includes a socket housing 202 and a conductive pin 201, and the pin 201 is arranged in the socket housing 202.

[0118] With the above structure, when the plug 1 is plugged into the socket 2, the elastic clamping member 102 in the plug 1, with the assistance of the auxiliary clamping structure 103, can greatly increase its clamping force on the pin 201 in the socket 2, thereby ensuring electrical contact and electrical conductivity between the two and having better anti-loosening capability.

[0119] Furthermore, the socket housing 202 is provided with a plug insertion cavity 2021 for inserting the plug 1, and at least one end of the pin 201 is located in the plug insertion cavity 2021;

[0120] The part of the plug housing 101 used to be inserted into the plug insertion cavity 2021 is formed as a plug housing insertion portion 1016, and a locking protrusion 1017 is protruded on the first plug outer side wall 1016a of the plug housing insertion portion 1016. A locking groove 2022 is correspondingly provided on the first insertion cavity inner wall 2021a of the plug insertion cavity 2021 opposite to the first plug outer side wall 1016a, and when the plug housing insertion portion 1016 is fully inserted into the plug insertion cavity 2021, the locking protrusion 1017 is located in the locking groove 2022.

[0121] With the above structure, when the plug housing insertion portion 1016 is fully inserted into the plug insertion cavity 2021 , the locking protrusion 1017 is located in the locking slot 2022 to achieve locking, which can greatly improve the anti-loosening capability of the plug 1 .

[0122] Furthermore, along the direction in which the plug housing insertion portion 1016 is inserted into the plug insertion cavity 2021, the end surface of the locking protrusion 1017 that first contacts the first insertion cavity inner wall 2021a and / or the side of the first insertion cavity inner wall 2021a that first contacts the locking protrusion 1017 is provided with a first guide surface 3 for guiding the locking protrusion 1017 into the locking slot 2022;

[0123] Along the direction in which the plug housing 101 is pulled out of the plug insertion cavity 2021 , the end surface of the locking protrusion 1017 that first contacts the locking groove 2022 and / or the side of the locking groove 2022 that first contacts the locking protrusion 1017 are provided with a second guide surface 4 for guiding the locking protrusion 1017 to disengage from the locking groove 2022 ;

[0124] Specifically, the first guide surface 3 and the second guide surface 4 are inclined surfaces or arc-shaped surfaces.

[0125] The above structure makes the structural arrangement of the plug 1 and the socket 2 more reasonable. The arrangement of the first guide surface 3 makes it easier for the user to insert the insertion part of the plug 1 into the plug insertion cavity 2021; the arrangement of the second guide surface 4 makes it easier for the user to unlock the locking protrusion 1017 and the locking slot 2022 when pulling the insertion part of the plug 1 out of the plug insertion cavity 2021.

[0126] Furthermore, along the direction of the plug shell insertion portion 1016 being inserted into the plug insertion cavity 2021, a locking tongue structure 1018 is provided at the end of the plug shell insertion portion 1016 that first enters the plug insertion cavity 2021, and a locking hole slot structure 2023 for inserting the locking tongue structure 1018 is provided on the side of the plug insertion cavity 2021 opposite to its opening, and when the plug shell insertion portion 1016 is fully inserted into the plug insertion cavity 2021, the locking tongue structure 1018 is inserted into the locking hole slot structure 2023.

[0127] With the above structure, when the plug housing insertion portion 1016 is fully inserted into the plug insertion cavity 2021, the locking tongue structure 1018 is inserted into the locking hole slot structure 2023. The two cooperate to lock and prevent the plug 1 from moving or rotating sideways, thereby ensuring a stable and reliable connection between the plug 1 and the socket 2.

[0128] The above structure is particularly suitable for the case where the socket 2 adopts a semi-open structure similar to a guide rail terminal block.

[0129] Furthermore, the lock tongue structure 1018 includes a lock tongue connecting portion 1018a, and a first lock tongue block 1018b and a second lock tongue block 1018c provided on both sides of the lock tongue connecting portion 1018a, and the first lock tongue block 1018b and the second lock tongue block 1018c are located on both sides of the clamping opening 1022; correspondingly, the lock hole slot structure 2023 includes a lock hole connecting slot 2023a matching the lock tongue connecting portion 1018a, and a lock hole connecting slot 2023a provided on the lock tongue connecting portion 1018a. The first lock hole groove 2023b and the second lock hole groove 2023c are respectively matched with the first lock tongue block 1018b and the second lock tongue block 1018c on both sides of the hole connecting portion, and the first lock hole groove 2023b and the second lock hole groove 2023c are located on both sides of the pin 201. When the plug housing insertion portion 1016 is fully inserted into the plug insertion cavity 2021, the bottom surface of the lock hole connecting groove 2023a is opposite to the bottom surface of the lock tongue connecting portion 1018a.

[0130] The above structure makes the structural arrangement of the lock tongue structure 1018 and the lock hole slot structure 2023 more reasonable, ensuring stable and reliable locking cooperation between the two.

[0131] Furthermore, the front sides of the first lock hole slot 2023b and the second lock hole slot 2023c are respectively provided with a first communication port 2023d and a second communication port 2023e identical thereto.

[0132] With the above structure, the first communication port 2023d and the second communication port 2023e are provided so that when a user inserts the plug 1 , the user can observe whether the first locking tongue block 1018b and the second locking tongue block 1018c are inserted into the first lock hole slot 2023b and the second lock hole slot 2023c .

[0133] Furthermore, a limiting guide portion 1019 is provided on the second plug outer side wall 1016b of the plug shell insertion portion 1016, and a limiting guide groove 2024 matching the limiting guide portion 1019 is correspondingly provided on the second insertion cavity inner wall 2021b of the plug insertion cavity 2021 opposite to the second plug outer side wall 1016b, and the limiting guide groove 2024 extends along the insertion direction of the plug shell insertion portion 1016.

[0134] With the above structure, the cooperation between the limiting guide portion 1019 and the limiting guide groove 2024 can play a guiding role in the process of inserting the plug 1 into the socket 2, and has a certain limiting effect.

[0135] Furthermore, the limiting guide portion 1019 includes a limiting guide block 1019a and a first limiting guide connecting portion 1019b for connecting the limiting guide block 1019a and the second plug outer side wall 1016b; correspondingly, the limiting guide groove 2024 includes a first limiting guide groove 2024a matching the limiting guide block 1019a, and a second limiting guide groove 2024b for connecting the first limiting guide groove 2024a and the plug insertion cavity 2021, and the second limiting guide groove 2024b matches the first limiting guide connecting portion 1019b;

[0136] The thickness of the limiting guide block 1019a is greater than the thickness of the first limiting guide connection portion 1019b. Correspondingly, the width of the first limiting guide groove 2024a is greater than the width of the second limiting guide groove 2024b.

[0137] With the above structure, the structures of the limiting guide portion 1019 and the limiting guide groove 2024 are more reasonable, and the two can cooperate better to better achieve guidance and limiting.

[0138] Furthermore, the second plug outer side wall 1016b and the first plug outer side wall 1016a are the same side wall of the plug shell insertion portion 1016, and correspondingly, the second insertion cavity inner wall 2021b and the first insertion cavity inner wall 2021a are the same inner wall of the plug insertion cavity 2021; along the direction of the plug shell insertion portion 1016 being inserted into the plug insertion cavity 2021, the locking protrusion 1017 is located in front of the limiting guide portion 1019, and the locking slot 2022 is located in front of the limiting guide slot 2024.

[0139] Along the direction of the plug shell insertion part 1016 being inserted into the plug insertion cavity 2021, the locking protrusion 1017 is located in front of the limiting guide part 1019, and the locking slot 2022 is located in front of the limiting guide slot 2024. It can be understood that in the process of the plug shell insertion part 1016 being inserted into the plug insertion cavity 2021, the locking protrusion 1017 enters the plug insertion cavity 2021 before the limiting guide part 1019, and the plug shell insertion part 1016 first passes through the limiting guide slot 2024 and then passes through the locking slot 2022.

[0140] The above structure makes the structure of the plug 1 and the socket 2 more reasonable; during installation, the locking protrusion 1017 first passes through the limiting guide groove 2024, and then enters the locking slot 2022 after being retracted and pressed. This greatly reduces the distance that the locking protrusion 1017 needs to move after being squeezed, making it easier to insert the plug 1 during actual use.

[0141] Furthermore, the portion of the plug housing 101 that is not inserted into the plug insertion cavity 2021 is formed as a plug housing body 101A, and the side of the plug housing body 101A on the same side as the second plug outer side wall 1016b protrudes from the second plug outer side wall 1016b, and the limiting guide portion 1019 includes a second limiting guide connecting portion 1019c, and the two ends of the second limiting guide connecting portion 1019c are respectively connected to the limiting guide block 1019a and the side of the plug housing body 101A facing the plug housing insertion portion 1016.

[0142] With the above structure, the structural arrangement of the plug housing 101 is more reasonable, and the arrangement of the second limiting guide connecting portion 1019c makes the arrangement of the limiting guide block 1019a more stable.

Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present application should be included in the scope of protection of the present application.
