Description

Technical Field

[0001] The present application relates to the technical field of terminal connectors, and in particular to a plug-in terminal connector. Background Art

[0002] A plug-in terminal connector, also known as a plug-in terminal block or a plug-in connector, is an electrical connector specifically designed to connect wires or conductors on a circuit board. This connector has a unique design and can be directly inserted into a pre-designed slot or jack for quick and easy connection. It is widely used in various electronic devices, such as televisions, stereos, computer motherboards, etc., as well as in industrial automation, transportation, ships and other fields. The main reason for its popularity is its significant advantages such as easy connection, stable connection performance, and low contact resistance.

[0003] During the use of existing plug-in terminal connectors, the connecting terminals often need to be connected or removed from the connecting base multiple times. After long-term use, the connection between the connecting terminals and the connecting base is likely to become loose, thereby affecting the stability of the connection between the connecting terminals and the connecting base. In addition, during use, the connecting terminals and the connecting base are easily damaged during the process of plugging and unplugging. After damage, the connecting terminals or the connecting base need to be replaced before they can continue to be used normally.

[0004] Therefore, there is an urgent need for a plug-in terminal connector that can maintain high performance after long-term use. Summary of the invention

[0005] The present application provides a plug-in terminal connector, which can facilitate long-term use and maintain high performance.

[0006] The present application provides a plug-in terminal connector, which adopts the following technical solution:

[0007] A plug-in terminal connector comprises a connection base and a plurality of connection terminals, wherein the connection terminals are detachably connected to the connection base;

[0008] The connecting base includes a base body, a plurality of conductive pins, a matching piece and a positioning assembly;

[0009] The plurality of conductive needles are arranged on the seat body, and the matching piece is provided with a plurality of through holes for the conductive needles to pass through and a plurality of clearance grooves for the conductive needles to pass through, and the through holes are communicated with the clearance grooves; the positioning assembly is arranged on the seat body, and includes a plurality of first positioning pieces and a plurality of second positioning pieces, and the first positioning pieces and the second positioning pieces are both movable relative to the seat body; the matching piece is provided with a matching groove, and the matching piece is also provided with a plurality of through openings for connecting the matching groove with the outside, and the matching piece has a plurality of clamping parts in the matching groove; when the plurality of conductive needles are respectively inserted into the plurality of clearance grooves and the matching piece abuts against the seat body, the positioning assembly can enter the matching groove, the plurality of first positioning pieces respectively pass through the plurality of through openings, the plurality of second positioning pieces are clamped and matched with the plurality of clamping parts, and the plurality of first positioning pieces and the plurality of second positioning pieces can both limit the matching piece from moving in the direction away from the seat body along the direction in which the conductive needles are passed through;

[0010] The connecting terminal comprises a conductive member and a connecting member, wherein the conductive member is arranged on the connecting member;

[0011] The connecting member is adapted to the giving way slot, and a plugging slot for the conductive pin to be inserted is provided on the connecting member, and after the conductive pin is inserted into the plugging slot, the conductive member can contact the corresponding conductive pin;

[0012] A snap-in piece is movably connected to the connecting piece, and the matching piece is provided with a snap-in slot on one side of the clearance slot for the snap-in piece to be inserted into, and the snap-in slot is communicated with the outside world; after the connecting piece is inserted into the clearance slot, the conductive needle can be inserted into the plug-in slot, and the snap-in piece can be inserted into the snap-in slot to restrict the connecting piece from leaving the clearance slot.

[0013] By adopting the above technical solution, the fitting is detachably connected to the base body through the positioning assembly. After the fitting is connected to the base body, a plurality of connecting terminals can be detachably connected to the connecting base, thereby ensuring that it has high performance in use. In addition, the loss caused by plugging and unplugging between the connecting terminals and the connecting base can be concentrated on the fitting. When the fitting becomes loose or the structure is damaged due to long-term use, replacing the fitting can maintain a high performance between the connecting terminals and the connecting base for long-term use.

[0014] Optionally, the first positioning member is fixed relative to the seat body and has elasticity, and the first positioning member can pass through the through-opening after interference fit with the corresponding through-opening;

[0015] The second positioning member is fixed relative to the seat body and the matching member is elastic at a position close to the clamping portion. During the process of the second positioning member entering the matching groove, the second positioning member can be deformed to be clamped with the clamping portion after contacting the clamping portion.

[0016] By adopting the above technical solution, the mating piece is connected to the positioning assembly through the elastic deformation of the first positioning piece and the clamping portion. It is easy to operate and can form a relatively firm connection relationship between the mating piece and the base body, thereby effectively improving the stability between the connecting terminal and the connecting base.

[0017] Optionally, the positioning assembly further includes a body and a driving gear, and includes a first positioning member and two second positioning members, and the first positioning member and the second positioning member are both movably connected to the body;

[0018] The two second positioning members are respectively located on both sides of the body, and the movable direction of the second positioning members is perpendicular to the insertion direction of the conductive needle; the first positioning member can rotate relative to the body, and the rotation axis of the first positioning member is parallel to the insertion direction of the conductive needle;

[0019] The driving gear is arranged on the body and connected to the first positioning member. The second positioning member has a rack structure. The driving gear is meshed with the rack structure of the second positioning member. The rotation of the first positioning member can drive the driving gear to rotate, thereby driving the two second positioning members to move synchronously and in opposite directions.

[0020] By adopting the above-mentioned technical scheme, the position state of the positioning assembly can be switched by controlling the rotation of the first positioning member, which makes it easier for the matching member to be connected or disconnected with the seat body through the positioning member. At the same time, it can reduce the loss caused by the detachable connection between the matching member and the seat body, thereby effectively extending the service life of the matching member and facilitating its long-term use.

[0021] Optionally, the positioning assembly also includes a first elastic member, which is arranged on the body and can drive the first positioning member to rotate to an extreme position and maintain it; when the first positioning member rotates to another extreme position, the first positioning member can pass through the through opening and the distance between the two second positioning members is minimized.

[0022] By adopting the above technical solution, the positioning component can be easily connected to the base body after the matching component is connected to the base body, so as to reduce the probability that the connection between the matching component and the base body is released due to the change of the position state of the positioning component after being subjected to external force.

[0023] Optionally, the first positioning member has a plurality of guide surfaces at one end away from the body, and when the body enters the mating groove, the position of the mating groove wall close to the through opening can contact the guide surfaces, and when the mating member moves toward the direction close to the seat body, the first positioning member can be driven to rotate by overcoming the force of the first elastic member.

[0024] By adopting the above technical solution, the degree of automation of the process in which the matching piece forms a connection with the seat body through the positioning assembly can be effectively improved. During the connection between the matching piece and the seat body, the first positioning piece can be driven to rotate and the second positioning piece can be driven to slide and retract, which is convenient for the first positioning piece to pass through the through opening and the second positioning piece to enter the matching groove. After the matching piece is installed in place, the positioning assembly can automatically switch the position state to form a connection between the matching piece and the seat body, thereby further facilitating operation.

[0025] Optionally, the positioning assembly further includes a second elastic member, and two ends of the second elastic member are respectively connected to the body and the first positioning member;

[0026] The first positioning member can slide relative to the body, and the sliding direction of the first positioning member is parallel to the insertion direction of the conductive needle;

[0027] The second elastic member can drive the first positioning member to slide to the extreme position in the direction away from the body. After the first positioning member passes through the through opening, the second elastic member drives the first positioning member at the extreme position to abut against the side of the matching member away from the seat body.

[0028] By adopting the above technical solution, the second elastic member can facilitate the rotation of the first positioning member under the action of the matching member, and at the same time can drive the first positioning member to quickly pass through the through opening when the first positioning member rotates to a position where it can pass through the through opening, thereby further facilitating the use of the positioning assembly.

[0029] Optionally, the positioning assembly also includes an adjusting member, which is inserted through the first positioning member in a direction parallel to the sliding direction of the first positioning member, and one end of the adjusting member close to the body is threadedly engaged with the body, and one end of the adjusting member away from the body is located on one side of the first positioning member and is against the first positioning member.

[0030] By adopting the above technical solution, the user can conveniently improve the positioning effect of the first positioning member on the matching member by controlling the adjustment member, thereby effectively improving the positioning effect of the positioning component on the matching member after installation on the seat body.

[0031] Optionally, the positioning assembly also includes a plurality of deformable members with elastic deformation capabilities, and the plurality of deformable members are respectively arranged on the two second positioning members, and the deformable members are partially exposed at one end of the second positioning member away from the body and form a slot for the snap-in portion to be snapped into, and the slot is flared in the direction away from the body.

[0032] By adopting the above technical solution, it is possible to further facilitate the snap-fitting between the snap-fitting portion and the second positioning member. At the same time, the matching member can adjust its own installation position on the base body during the snap-fitting process between the snap-fitting portion and the second positioning member, and can further improve the positioning effect of the second positioning member on the matching member, thereby making the positioning of the matching member on the base body more stable and more accurate.

[0033] Optionally, the end of the deformable member away from the slot has an abutment portion, the abutment portion is located on the side of the first positioning member close to the body and abuts against the second elastic member, and the abutment portion can drive the deformable member to deform close to the slot after being acted upon by external force.

[0034] By adopting the above technical solution, the control adjusting member can improve the positioning effect of the first positioning member on the matching member, and at the same time, the force between the deformable member and the clamping portion can be increased to improve the positioning effect of the second positioning member on the matching member.

[0035] Optionally, the clamping member is fixedly connected to the connecting member and is elastic, the matching member has a protrusion on the groove wall of the clearance groove, and the protrusion is located on a side of the clamping groove away from the through hole;

[0036] When the clamping member is inserted into the clearance groove along with the connecting member, the clamping member can contact the protruding portion, and the protruding portion can guide the clamping member to deform and then be clamped into the clamping groove.

[0037] By adopting the above technical solution, the user can easily achieve a detachable connection between the connecting terminal and the connecting base, and at the same time can effectively reduce the loss caused by the detachable connection between the connecting terminal and the connecting base, thereby reducing the probability of loose connection or even failure after long-term use.

[0038] In summary, the present application includes at least one of the following beneficial effects:

[0039] 1. It can effectively reduce the loss of the plug-in terminal connector during use, extend its service life, facilitate its long-term use, and maintain high performance;

[0040] 2. The wear of the plug-in terminal connector during use can be concentrated on the mating parts, and the mating parts can be easily replaced, so as to further facilitate its long-term use;

[0041] 3. It can make the detachable connection process between the matching part and the seat body more convenient and quick in an automated manner, and can also reduce the wear of the matching part during the installation process;

[0042] 4. It can effectively improve the stability and position accuracy of the installation of the matching parts, so as to improve the effect and performance of the detachable connection between the final connection terminal and the connection base. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The following is combined with Figure 1-7 This application is described in further detail.

[0052] Embodiment 1:

[0053] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a plug-in terminal connector, including a plurality of connection terminals 2 and a connection base 1, each connection base 1 can be detachably connected to a plurality of connection terminals 2. After the connection terminal 2 is connected to the connection base 1, the circuit between the connection terminal 2 and the connection base 1 can be connected. In this embodiment, the plug-in terminal connector preferably includes three connection terminals 2 and one connection base 1.

[0054] The connection base 1 includes a base body 11, a plurality of conductive pins 12, a matching piece 13 and a positioning assembly 14. The base body 11 is the main body of the connection base 1 and has a corresponding circuit structure inside; the conductive pins 12 are used to form a circuit connection between the connection base 1 and the connection terminal 2; the matching piece 13 can form a detachable connection result for the connection terminal 2 on the base body 11, so as to form a connection between the connection terminal 2 and the connection base 1; the positioning assembly 14 is used to control the connection between the matching piece 13 and the base body 11.

[0055] Reference Figure 1 and Figure 3 Preferably, the seat body 11 is a rectangular parallelepiped structure as a whole, and the end surface of the seat body 11 with the largest area is preferably used for the installation of the matching piece 13.

[0056] Reference Figure 1 and Figure 2 , preferably, the conductive needle 12 is in an elongated rod-shaped structure as a whole. One end of the conductive needle 12 in the length direction is located inside the base 11, and forms a circuit connection with the circuit structure inside the base 11; the other end of the conductive needle 12 in the length direction is exposed on one side of the end face of the base 11 for mounting the matching piece 13, and the length direction of the exposed part of the conductive needle 12 is perpendicular to the end face of the base 11 for mounting the matching piece 13. In the present embodiment, correspondingly, the connecting base 1 preferably includes a total of three conductive needles 12, and the three conductive needles 12 are on the base 11 close to one end of the length direction of the base 11, and the three conductive needles 12 are evenly spaced on the base 11 along the width direction of the base 11.

[0057] Reference Figure 1 and Figure 4 The positioning assembly 14 includes a body 143, a plurality of first positioning members 141 and a plurality of second positioning members 142. In this embodiment, the positioning assembly 14 preferably includes one first positioning member 141 and two second positioning members 142.

[0058] The body 143 is a rectangular parallelepiped structure, and the body 143 is fixedly mounted on the end surface of the base 11 for mounting the mating member 13. In this embodiment, the length direction of the body 143 is preferably perpendicular to the length direction of the conductive pin 12 and parallel to the width direction of the base 11, and the body 143 is preferably located on the side of the conductive pin 12 away from the end thereof on the base 11.

[0059] The first positioning member 141 is fixedly mounted on one end of the body 143 away from the base 11 , and the two second positioning members 142 are respectively fixedly mounted on two ends of the body 143 in the length direction.

[0060] Reference Figure 2 and Figure 4 The mating piece 13 is a double-layer stepped structure that is approximately a rectangular parallelepiped. The lower stepped structure of the mating piece 13 is used to form a connection with the positioning assembly 14 so that the mating piece 13 itself can be installed and fixed on the base body 11.

[0061] The mating piece 13 has a mating groove 131 on the stepped structure at the lower level. The mating groove 131 is generally in the shape of a rectangular parallelepiped structure. The mating groove 131 forms an opening on the end surface of the mating piece 13 that abuts against the seat body 11. The positioning assembly 14 can enter the mating groove 131 through the opening of the mating groove 131.

[0062] The step structure at the lower level of the matching member 13 also has a through hole 132 for the first positioning member 141 to pass through, and the through hole 132 allows the end of the matching groove 131 away from its own opening to communicate with the outside world. The end of the first positioning member 141 away from the body 143 has an arrow structure facing away from the seat body 11. The first positioning member 141 is elastic and can move relative to the body 143 through elastic deformation, and the structure of other parts of the first positioning member 141 is compatible with the through hole 132. In this embodiment, the first positioning member 141 is preferably made of rubber material.

[0063] The mating piece 13 has a snap-fitting portion 133 at both ends of the mating groove 131 in the length direction for forming a snap-fitting with the second positioning piece 142. The two snap-fitting portions 133 correspond to the two second positioning pieces 142 one by one, respectively, and the parts of the mating portion close to the two snap-fitting portions 133 have elastic deformation capabilities, and space is reserved on both sides of the snap-fitting portion 133 to facilitate its elastic deformation.

[0064] When the matching member 13 is installed and fixed on the base body 11 through the positioning assembly 14 , the first positioning member 141 first enters the matching groove 131 , and the body 143 and the two second positioning members 142 enter the matching groove 131 subsequently.

[0065] After the first positioning member 141 enters the matching groove 131, its arrow structure can penetrate into the through opening 132 and undergo elastic deformation, so that it can pass through the through opening 132; when the matching member 13 contacts and abuts against the seat body 11, the arrow structure of the first positioning member 141 can just pass through the through opening 132 and the side of the stepped structure at the lower level of the matching member 13 away from the seat body 11. At this time, the arrow structure of the first positioning member 141 can be deformed and restored, abutting against the side of the stepped structure at the lower level of the matching member 13 away from the seat body 11, and at this time, the first positioning member 141 can limit the movement of the matching member 13 in the direction away from the body 143.

[0066] After the second positioning member 142 enters the matching groove 131, it will first contact with the corresponding snap-fit ​​portion 133, causing the snap-fit ​​portion 133 to deform in a direction away from the matching groove 131 so that the second positioning member 142 can enter the matching groove 131; after the second positioning member 142 enters the matching groove 131 and the matching member 13 contacts and abuts against the seat body 11, the snap-fit ​​portion 133 can be deformed and restored. At this time, the second positioning member 142 is located on the side of the corresponding snap-fit ​​portion 133 away from the seat body 11 and abuts against it, and at this time, the second positioning member 142 can form a snap-fit ​​with the corresponding snap-fit ​​portion 133, which limits the movement of the matching member 13 in a direction away from the body 143.

[0067] When removing and replacing the matching piece 13 , the matching piece 13 only needs to be pulled out in a direction away from the base 11 . The first positioning piece 141 and the two clamping portions 133 can be elastically deformed by the force, so that the matching piece 13 can be separated from the base 11 smoothly.

[0068] Furthermore, in order to facilitate the user to know the snap-fitting condition between the second positioning member 142 and the snap-fitting portion 133 in the matching groove 131, it is preferred that observation ports 134 are opened on both sides of the through opening 132 on the lower step structure of the matching member 13, and the observation ports 134 are connected to the matching groove 131. The two observation ports 134 correspond one-to-one to the two snap-fitting portions 133, and the user can observe the snap-fitting condition between the positioning member and the corresponding snap-fitting portion 133 through the observation ports 134.

[0069] The stepped structure of the upper layer of the mating piece 13 is provided with a plurality of through holes 135 for the conductive pins 12 to pass through and a plurality of clearance grooves 136 for the connection terminals 2 to form a connection with the connection base 1. The plurality of through holes 135 correspond to the plurality of clearance grooves 136 one by one, and the through holes 135 are communicated with the corresponding clearance grooves 136. One end of the through hole 135 away from the corresponding clearance groove 136 penetrates through the end surface of the mating piece 13 that contacts and abuts against the base body 11 to form an opening, and one end of the clearance groove 136 away from the corresponding through hole 135 penetrates through the stepped structure of the upper layer to form an opening.

[0070] When the matching piece 13 is installed and fixed on the base body 11 through the positioning assembly 14, the three conductive pins 12 can pass through the corresponding through holes 135 respectively; after the matching piece 13 is installed and fixed on the base body 11 through the positioning assembly 14, the exposed parts of the three conductive pins 12 will be mainly located in the corresponding clearance grooves 136.

[0071] The connection terminal 2 includes a conductive member 22 and a connecting member 21. The conductive member 22 enables the connection terminal 2 to have circuit connectivity; and the connecting member 21 is used to achieve a detachable connection between the connection terminal 2 and the connection base 1.

[0072] The connector 21 is a rectangular parallelepiped structure, and the connector 21 is adapted to the clearance groove 136. The connector 21 has a plug-in groove 211 for inserting the conductive pin 12 and adapted to the conductive pin 12. The opening direction of the plug-in groove 211 is parallel to the length direction of the connector 21, and the plug-in groove 211 forms an opening at one end of the length direction of the connector 21.

[0073] The conductive member 22 is fixedly installed on the connector 21 at a position away from the opening of the plug-in slot 211. When the connector 21 is fully inserted into the clearance slot 136, the corresponding conductive pin 12 will be inserted into the corresponding plug-in slot 211. At this time, the end of the conductive pin 12 away from the seat body 11 can contact the corresponding conductive member 22 to form a circuit connection.

[0074] Furthermore, in order to facilitate the connection between the connecting member 21 and the matching member 13 to have sufficient stability after being plugged in and to facilitate the user to release the connection between the two, the connecting terminal 2 also includes a clamping member 23.

[0075] One end of the clamping member 23 is fixedly connected to a position on one side of the matching member 13 near the conductive member 22. The clamping member 23 is elastic and can be bent and deformed relative to the connecting member 21. There is enough space between the clamping member 23 and the connecting member 21 for the clamping member 23 to bend in a direction close to the matching member 13. In this embodiment, the clamping member 23 is preferably a plastic product with elasticity, and the connecting member 21 preferably has a groove on its end surface near the clamping member 23 to make way for the clamping member 23 to bend and deform inward.

[0076] The stepped structure of the upper layer of the mating piece 13 is also provided with a plurality of engaging grooves 137 for the engaging member 23 to engage with the mating piece 13, and the plurality of engaging grooves 137 correspond one to one with the plurality of clearance grooves 136. In this embodiment, preferably, the mating piece 13 is provided with a total of three engaging grooves 137, which are communicated with the corresponding clearance grooves 136 and penetrate through one end of the mating piece 13 away from the mating groove 131 to form an opening.

[0077] The matching member 13 has protrusions 138 on the groove walls of the three clearance grooves 136 close to the corresponding engaging grooves 137 for guiding the engaging member 23 to bend and deform. The protrusions 138 are located on a side of the corresponding engaging groove 137 away from the corresponding through hole 135 .

[0078] When the clip 23 is inserted into the clearance groove 136 together with the connector 21, the clip 23 will contact the corresponding protrusion 138, and the protrusion 138 will then guide the clip 23 to bend and deform in the direction close to the corresponding connector 21, so that the clip 23 can pass through the space between the protrusion 138 and the connector 21. After the connector 21 is fully inserted into the clearance groove 136, the end of the clip 23 will deform and recover to be snapped into the clip groove 137, so as to improve the stability of the plug-in fit between the connector 21 and the mating member 13.

[0079] When the connection between the connecting member 21 and the matching member 13 needs to be released, the corresponding end of the clamping member 23 can be pressed at the opening of the corresponding clamping groove 137 to release the clamping member 23 from the matching member 13, and the connecting member 21 can be pulled out.

[0080] The implementation principle of a plug-in terminal connector in the embodiment of the present application is as follows:

[0081] The fitting member 13 is installed and fixed on the base body 11 through the positioning assembly 14, so that the first positioning member 141 passes through the through hole 132 to limit the fitting member 13, and the second positioning member 142 is engaged with the corresponding clamping portion 133 to limit the fitting member 13, thereby improving the stability of the connection between the fitting member 13 and the base body 11;

[0082] The detachable connection between the connection terminal 2 and the connection base 1 facilitates operation and reduces loss, thereby extending the service performance of the circuit connection between the connection terminal 2 and the connection base 1;

[0083] During the process of connecting and disconnecting the connecting terminal 2 and the connecting base 1, the loss can be concentrated on the matching piece 13, reducing the damage to the circuit, and the matching piece 13 is easy to disassemble and replace, thereby effectively extending the service life of the plug-in terminal connector.

[0084] Embodiment 2:

[0085] Reference Figure 1 and Figure 5 The difference between this embodiment and embodiment 1 lies in the positioning component 14.

[0086] Reference Figure 6 and Figure 7The first positioning member 141 and the second positioning member 142 are both movably connected to the body 143 , and the positioning assembly 14 further includes a plurality of first elastic members 145 , a plurality of second elastic members 147 , an adjusting member 144 , a driving gear 146 and a plurality of deformable members 148 .

[0087] The adjusting member 144 is in a cylindrical structure as a whole. One end of the adjusting member 144 in the length direction penetrates into the body 143 and is threadedly matched with the body 143 . The axial direction of the adjusting member 144 is parallel to the length direction of the conductive needle 12 .

[0088] The first positioning member 141 is sleeved and installed on the adjusting member 144, and can slide relative to the adjusting member 144 along the axis direction of the adjusting member 144, and can rotate relative to the adjusting member 144 with the axis of the adjusting member 144 as the axis. The adjusting member 144 has a limiting portion 1441 at one end away from the body 143 for limiting the first positioning member 141 from being separated from the adjusting member 144. At this time, the movable range of the first positioning member 141 is located between the limiting portion 1441 and the body 143.

[0089] The second positioning member 142 is installed on a side of the body 143 away from the base 11 , and is slidably connected to the body 143 . The sliding direction of the second positioning member 142 is parallel to the length direction of the body 143 .

[0090] A plurality of second elastic members 147 are installed between the arrow structure of the first positioning member 141 and the body 143. One end of the second elastic member 147 abuts against the bottom of the arrow structure of the first positioning member 141, and the other end abuts against the two second positioning members 142 at the same time. The second elastic member 147 can drive the first positioning member 141 to slide in a direction away from the body 143, so that the first positioning member 141 has a tendency to maintain contact and abut against the limit member. In this embodiment, the positioning assembly 14 preferably includes a second elastic member 147, and the second elastic member 147 is preferably a compression spring. The second elastic member 147 is sleeved outside the adjusting member 144, and the end of the second elastic member 147 away from the first positioning member 141 is fixedly connected with a gasket for contacting and abutting against the two second positioning members 142 at the same time.

[0091] Further, the through opening 132 on the matching member 13 is preferably matched with the arrow structure of the first positioning member 141. When the first positioning member 141 is rotated to a certain position relative to the adjusting member 144, the arrow structure of the first positioning member 141 can just pass through the through opening 132, and other structures of the first positioning member 141 can smoothly penetrate the through opening 132. In this embodiment, it is preferred that the arrow structure of the first positioning member 141 can just pass through the through opening 132 of the matching member 13 when the length direction is rotated to be parallel to the length direction of the seat body 11.

[0092] Furthermore, it is preferred that the arrow structure of the first positioning member 141 has a plurality of guide surfaces 1411 for contacting the mating member 13. In this embodiment, it is preferred that the arrow structure of the first positioning member 141 has two guide surfaces 1411 in total, the guide surface 1411 is located at one end of the arrow structure of the first positioning member 141 away from the body 143, and the two guide surfaces 1411 are respectively located at both ends of the arrow structure of the first positioning member 141 in the length direction.

[0093] During the process of the fitting 13 being installed and fixed on the seat body 11 through the positioning assembly 14, if the position state of the arrow structure of the first positioning member 141 cannot directly pass through the through opening 132 at this time, the position close to the through opening 132 on the fitting 13 will simultaneously contact the two guide surfaces 1411 on the first positioning member 141; at this time, if the fitting 13 applies a force to the two guide surfaces 1411 in the direction close to the machine body 143, the first positioning member 141 can overcome the force of the second elastic member 147 and slide in the direction close to the machine body 143, and at the same time, the first positioning member 141 can rotate relative to the adjusting member 144 under the action of the two guide surfaces 1411 until its position state can pass through the through opening 132; when the arrow structure of the first positioning member 141 rotates to its position state that can pass through the through opening 132, the second elastic member 147 will drive the first positioning member 141 to slide through the through opening 132 in the direction away from the machine body 143, so that the arrow structure of the first positioning member 141 is located outside the fitting 13.

[0094] Furthermore, the first positioning member 141 is preferably limited in its rotation relative to the adjusting member 144. In this embodiment, the first positioning member 141 preferably rotates at an angle of 90° relative to the adjusting member 144. When the first positioning member 141 rotates to an extreme position, its position state can pass through the through hole 132.

[0095] The driving gear 146 is mounted on the body 143 and is also sleeved outside the adjusting member 144. The driving gear 146 is rotatably connected to the body 143, and the rotation axis of the driving gear 146 coincides with the axis of the adjusting member 144. The driving gear 146 has a sleeve extending outward in a direction away from the body 143, and the sleeve is sleeved and matched with the first positioning member 141. The first positioning member 141 can slide relative to the sleeve along the axis direction of the adjusting member 144, and the first positioning member 141 can drive the driving gear 146 to rotate during the rotation relative to the adjusting member 144.

[0096] The second positioning members 142 are provided with rack structures along their sliding direction, and the rack structures on the two second positioning members 142 are respectively located on both sides of the driving gear 146 and mesh with the driving gear 146. When the driving gear 146 rotates, the two second positioning members 142 can be driven to slide synchronously and in opposite directions through the meshing between the driving gear 146 and the rack structures.

[0097] When the first positioning member 141 rotates to a position where it can pass through the through opening 132, the two second positioning members 142 slide to a position where the distance between them is the smallest, and during the installation of the matching member 13, a distance is maintained between the second positioning members 142 and the corresponding snap-fitting portions 133; when the first positioning member 141 rotates to another extreme position, the two second positioning members 142 slide to a position where the distance between them is the largest, and if the matching member 13 is installed to contact and abut against the seat body 11, the second positioning members 142 can contact the corresponding snap-fitting portions 133 and form a snap-fitting fit.

[0098] The first elastic member 145 is installed between the driving gear 146 and the body 143. The two ends of the first elastic member 145 are fixedly connected to the driving gear 146 and the body 143 respectively, and the first elastic member 145 can drive the driving gear 146 to rotate in a certain direction, so that the first positioning member 141 can rotate to the extreme position state when its position state cannot pass through the through hole 132 and maintain it. In this embodiment, the first elastic member 145 is preferably a torsion spring. Since the torsion spring is a common prior art, it will not be described here, and only its installation position is shown in the drawings.

[0099] When the mating piece 13 is installed so that the arrow structure of the first positioning piece 141 passes through the through opening 132 and is located outside the mating piece 13, the threaded cooperation between the control adjusting piece 144 and the body 143 can be controlled to control the position of the limiting portion 1441, so that a force can be applied to the arrow structure of the first positioning piece 141 in a direction close to the body 143 through the limiting portion 1441, so that the arrow structure of the first positioning piece 141 is pressed against the mating piece 13 and a force is applied to the mating piece 13 in a direction close to the seat body 11, thereby improving the positioning effect of the first positioning piece 141 on the mating piece 13.

[0100] The deformable member 148 is elastic, and a plurality of the deformable members 148 correspond one-to-one to a plurality of the second positioning members 142 . In this embodiment, correspondingly, the positioning assembly 14 preferably includes two deformable members 148 in total; and the deformable members 148 are preferably made of rubber material.

[0101] The deformable member 148 is installed inside the corresponding second positioning member 142, and one end of the deformable member 148 is exposed at a position on the second positioning member 142 where it contacts the snap-in portion 133 when snap-fitting with the snap-in portion 133. The deformable member 148 at this position forms a slot 1481 for the snap-in portion 133 to be snapped into, and the slot 1481 is flared in a direction away from the body 143.

[0102] When the clamping portion 133 is clamped into the clamping slot 1481, both sides of the clamping portion 133 and the side thereof close to the second positioning member 142 are in contact with the deformable member 148. In the process that the second positioning member 142 slides to gradually clamp the clamping portion 133 into the clamping slot 1481, the deformable member 148 can correct the installation position of the matching member 13 on the seat body 11, so that the installation position of the matching member 13 is more accurate; at the same time, the deformable member 148 will be squeezed after contacting the clamping portion 133, so that the clamping effect between the second positioning member 142 and the clamping portion 133 is enhanced, thereby improving the positioning effect of the second positioning member 142 on the matching member 13.

[0103] The other end of the deformable member 148 away from the groove has an abutment portion, which is exposed at the position where the second positioning member 142 contacts the gasket on the first elastic member 145. The action force of the first elastic member 145 can drive it to squeeze the abutment portion through the gasket, and during the sliding of the second positioning member 142, the gasket on the first elastic member 145 will maintain contact with the abutment portion, so that the elastic deformation of the deformable member 148 near the slot 1481 is intensified, thereby further improving the positioning effect of the second positioning member 142 on the mating member 13 and further correcting the installation position of the mating member 13.

[0104] The implementation principle of a plug-in terminal connector in the embodiment of the present application is as follows:

[0105] During the installation of the matching piece 13 on the base body 11, the matching piece 13 first contacts the arrow structure of the first positioning piece 141, and under the action of the two guide surfaces 1411, the first positioning piece 141 is driven to rotate until it can smoothly pass through the through opening 132, and at the same time, the two second positioning pieces 142 are driven to slide toward each other, so that the body 143 and the two second positioning pieces 142 can smoothly enter the matching groove 131; thereafter, the second elastic piece 147 will drive the first positioning piece 141 to pass through the through opening 132. When the arrow structure of the first positioning piece 141 passes through the through opening 132, the first elastic piece 145 will drive the driving gear 146 to rotate so that the first positioning piece 141 is rotated and reset to a position state where the matching piece 13 is restricted from leaving the base body 11, and at the same time, the two second positioning pieces 142 are driven to slide toward each other, so that the body 143 and the two second positioning pieces 142 can smoothly enter the matching groove 131; afterwards, the second elastic piece 147 will drive the first positioning piece 141 to pass through the through opening 132. When the arrow structure of the first positioning piece 141 passes through the through opening 132, the first elastic piece 145 will drive the driving gear 146 to rotate so that the first positioning piece 141 is rotated and reset to a position state where the matching piece 13 is restricted from leaving the base body 11, and at the same time, the two second positioning pieces 142 are driven to slide toward each other, so that the body 143 and the two second positioning pieces 142 can smoothly enter the matching groove 131; The member 142 will also slide in the reverse direction to form a snap fit with the corresponding snap-fit ​​portion 133; then, the threaded connection between the control adjusting member 144 and the body 143 is controlled, and a downward force is applied to the arrow structure of the first positioning member 141 through the limiting portion 1441, so that the first positioning member 141 is pressed against the matching member 13, thereby improving its positioning effect on the matching member 13, so as to reduce the probability of the connection between the matching member 13 and the seat body 11 being loosened; at the same time, after the deformation member 148 is deformed by the force of the second elastic member 147, the snap fit effect of the second positioning member 142 on the corresponding snap-fit ​​portion 133 can be improved, thereby improving the positioning effect of the second positioning member 142 on the matching member 13, so as to further reduce the probability of the connection between the matching member 13 and the seat body 11 being loosened;

[0106] When it is necessary to release the connection between the fitting 13 and the seat body 11, the threaded connection between the control adjusting member 144 and the body 143 is controlled to form a gap between the arrow structure of the first positioning member 141 and the fitting 13, and then the arrow structure of the first positioning member 141 is rotated so that it can pass through the through opening 132. At this time, the fitting 13 can be moved away from the seat body 11 to separate the fitting 13 from the seat body 11.

[0107] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
