[0036] like Figures 1 to 5 As shown, an embodiment discloses a pull-type connector, including a linkage member 100, a guide member 200 and a handle 300, wherein the linkage member 100 includes a front end 110 and a rear end 120, wherein the front end 110 can be used to extend into the assembly hole 11 of the member to be connected and be fixed circumferentially, and the guide member 200 is sleeved outside the middle part of the linkage member 100, wherein the first end and the front end 110 of the guide member 200 are both extended into the assembly hole 11, and a slide groove 410 and a protrusion 420 are respectively provided on the outer wall of the first end and the inner wall of the assembly hole 11, and the slide groove 410 and the protrusion 420 are slidably matched. The slide groove 410 includes a first groove section 411 arranged along the axial direction of the linkage member 100 and a second groove section 412 arranged along the circumferential direction of the linkage member 100. The two ends of the handle 300 are respectively slidably matched with the second end and the rear end 120 of the guide member 200. The handle 300 slides along the axial direction of the linkage member 100. The inner wall of the handle 300 and the outer wall of the second end are respectively provided with a slidably matched guide groove 430 and a buckle body 440. The guide groove 430 is arranged in a spiral shape, and when the buckle body 440 moves along the guide groove 430, the protrusion 420 slides along the second groove section 412.

[0037] The pull-type connector can assemble the linkage member 100, the guide member 200 and the handle 300. The guide member 200 can be sleeved outside the middle of the linkage member 100. One end of the handle 300 is slidably matched with the second end through the cooperation of the slide groove 410 and the protrusion 420. The other end of the handle 300 is slidably matched with the linkage member 100, and the handle 300 slides along the axial direction of the linkage member 100, and the front end 110 and the first end are extended into the assembly hole 11. The front end 110 can slide along the assembly hole 11, and the protrusion 420 can move along the first groove section 411. The front end 110 is fixed circumferentially in the assembly hole 11. The handle 300 that slides with the linkage member 100 cannot rotate, but the handle 300 slides with the second end of the guide member 200. As the handle 300 moves axially along the linkage member 100, the buckle body 440 moves along the guide groove 430, so that the guide member 200 rotates under the guidance of the guide groove 430. At the same time, the first end of the guide member 200 rotates relative to the inner wall of the assembly hole 11, and the protrusion 420 slides along the second groove section 412, so that the protrusion 420 is stuck in the second groove section 412. At this time, the front end 110 of the guide member 200 is locked with the member to be connected 10 and cannot be pulled out from the assembly hole 11. After the front end 110 of the linkage member 100 and the first end of the guide member 200 are inserted into the assembly hole 11 of the above-mentioned pull-type connector, it is only necessary to press the handle 300 toward the member to be connected 10 to drive the guide member 200 to rotate, thereby locking the first end of the guide member 200 and the member to be connected 10, thereby realizing a self-locking function, and the locking function can be realized by single-handed operation, which is simple to operate.

[0038] In one embodiment, if Figures 5 to 7 As shown, the slide groove 410 is provided on the outer wall of the first end, and the guide groove 430 is provided on the outer wall of the second end. In the circumferential direction of the guide member 200, the guide groove 430 and the second groove section 412 are provided in the same direction. Since the guide groove 430 and the slide groove 410 are both provided on the guide member 200 and are respectively located at the first end and the second end, the guide groove 430 and the slide groove 410 are provided in the same circumferential direction of the guide member 200, so that the sliding cooperation between the guide groove 430 and the buckle body 440 can drive the sliding cooperation between the protrusion 420 and the slide groove 410, and the cooperation of the two parts does not interfere with each other, so as to ensure that the above-mentioned pull-type connector can be self-locked by pressing the guide member 200 toward the member to be connected 10. At this time, the front end 110 and the first end can be extended into the assembly hole 11 first, the front end 110 and the first end can be guided and limited, and then the protrusion 420 can be aligned to enter the slide groove 410, which can be convenient for operation.

[0039] Specifically, Figure 5 for Figure 2 In the structure shown, the assembly state of the protrusion 420, the buckle body 440 and the guide member 200 is as follows: Figure 7 for Figure 6In the structure shown, the protrusion 420, the buckle body 440 and the guide member 200 are assembled, wherein when the handle 300 is pressed toward the member to be connected 10, the buckle body 440 on the handle 300 moves toward the direction close to the member to be connected 10, and the buckle body 400 is Figure 5 Move to the middle position Figure 7 The guide member 200 rotates under the guidance of the guide groove 430, so that the protrusion 420 is moved from Figure 5 Move the position in Figure 7 The middle position realizes self-locking.

[0040] Alternatively, if Figure 1 , Figure 3 and Figure 8 As shown, the linkage member 100 is provided with an axial groove 101, and the handle 300 is provided with a guide block 310 that slidably cooperates with the axial groove 101, so that the handle 300 can move along the axial direction of the linkage member 100.

[0041] Specifically, Figure 5 As shown, the guide member 200 is a cylindrical structure, and the guide groove 430 is spirally arranged along the outer circumferential surface of the guide member 200, that is, the guide groove 430 extends in the axial direction and circumferential direction of the guide member 200 at the same time, and the extension direction of the guide groove 430 in the circumferential direction of the guide member 200 is the same as the extension direction of the second groove section 412. It is ensured that when the guide member 200 is pressed against the member to be connected 10, the guide groove 430 can rotate the guide member 200 and make the protrusion 420 enter the second groove section 412 to achieve a self-locking effect.

[0042] In other embodiments, the protrusion 420 may also be provided at the first end of the guide member 200, and the slide groove 410 may also be provided on the inner wall of the assembly hole 11; the buckle body 440 may also be provided at the second end of the guide member 200, and the guide groove 430 may also be provided on the inner wall of the handle 300. In this case, a self-locking effect may also be achieved.

[0043] In one embodiment, if Figure 2 and Figure 6 As shown, a stopper 201 is protruded outward from the middle of the guide member 200, and the stopper 201 is used to abut against the member to be connected 10, and the slide groove 410 and the guide groove 430 are respectively arranged on both sides of the stopper 201. The stopper 201 can abut against the member to be connected 10, and limit the guide member 200 so that it will not be displaced too much relative to the member to be connected 10. At this time, the protrusion 420 will not abut the connection between the first groove section 411 and the second groove section 412, and the protrusion 420 will not be affected by large friction due to excessive contact force, and the sliding of the protrusion 420 along the second groove section 412 will be reduced, thereby reducing the resistance to the rotation of the guide member 200 and making the operation more labor-saving.

[0044] In other embodiments, the stopper 201 may not be provided, and the guide member 200 can be limited by the protrusion 420 abutting against the connection between the first groove section 411 and the second groove section 412 to prevent it from further penetrating into the assembly hole 11. At this time, the handle 300 can be pushed toward the part to be connected 10 to achieve self-locking.

[0045] In one embodiment, if Fig. 9 As shown, the guide member 200 includes a first body 210 and a second body 220, the first body 210 and the second body 220 are butt-jointed, a receiving cavity 202 is formed between the first body 210 and the second body 220, a slide groove 410 is provided on the first body 210, and a guide groove 430 is provided on the second body 220. A chip or a sensor can be placed in the receiving cavity 202 for function expansion, and different modules can be placed according to the use requirements, so as to have a wider application range.

[0046] Specifically, the first split body 210 and the second split body 220 are coaxially arranged so that both ends of the guide member 200 can rotate synchronously to achieve self-locking.

[0047] In one embodiment, if Figure 3 and Fig. 9 As shown, a first docking portion 221 is provided at one end of the second body 220 close to the first body 210, and the outer edge of the first docking portion 221 is folded toward the direction of the first body 210 to form a bayonet 22, and a slot 223 is provided on the inner side wall of the bayonet 222, and the length of the slot 223 is less than the depth of the bayonet 222, and a second docking portion 211 is provided at one end of the first body 210 close to the second body 220, and the second docking portion 211 is used to extend into the bayonet 222 and cooperate with the first docking portion 221 to form a blocking portion 201, and a protrusion 212 matching the slot 223 is provided on the second docking portion 211. Since the length of the slot 223 is smaller than the depth of the socket 222, the first docking portion 221 is docked with the second docking portion 211 so that the protrusion 212 is inserted into the slot 223. Then, a receiving cavity 202 can be formed between the first docking portion 221 and the bottom wall of the socket 222 for placing a chip or sensor. At this time, the first docking portion 221 and the second docking portion 211 can rotate synchronously, so that self-locking can be achieved by pressing the handle 300 toward the connected component 10.

[0048] In one embodiment, if Figure 1 and Figure 4As shown, a positioning portion 450 is provided on the inner wall of the assembly hole 11, and the positioning portion 450 is provided on the side of the protrusion 420 away from the handle 300. A first limiting groove 460 that slides with the positioning portion 450 and a second limiting groove that slides with the protrusion 420 are provided on the outer wall of the front end 110. The protrusion 420 can enter the first groove section 411 through the second limiting groove. When the protrusion 420 is located in the second groove section 412, the positioning portion 450 is located in the first limiting groove 460. At this time, when the front end 110 of the linkage member 100 and the first end of the guide member 200 extend into the assembly hole 11, the protrusion 420 in the assembly hole 11 slides with the second limiting groove. After the front end 110 passes the position of the protrusion 420, the protrusion 420 will continue to slide with the first groove section 411 of the slide groove 410, and the positioning portion 450 slides with the first limiting groove 460, which can achieve circumferential fixation of the linkage member 100 to prevent it from rotating. At this time, the handle 300 can use the linkage member 100 as a reference for movement. In the process of the handle 300 approaching the part to be connected 10, the handle 300 will not rotate. Through the cooperation of the guide groove 430 and the buckle body 440, the guide member 200 is rotated to achieve the self-locking of the above-mentioned pull-type connector.

[0049] In other embodiments, an elastic buckle is provided on the inner wall of the assembly hole 11, and a placement hole is provided on the inner wall of the assembly hole 11. The elastic buckle includes an elastic member and a protrusion. The elastic member is located in the placement hole, and the protrusion is connected to the elastic member and is partially located outside the placement hole. The protrusion is an arc surface structure, and a matching recess matching the protrusion is provided on the outer wall of the front end 110. At this time, when the matching recess on the front end 110 moves to the position of the protrusion, the protrusion can be snapped into the matching recess to achieve circumferential fixation of the linkage 100.

[0050] In one embodiment, if Fig.10 and Fig.11 As shown, the pull-type connector further includes a contact pin 500 and an abutment member 600. A mounting hole 102 is provided in the linkage member 100, and an annular step 103 is provided in the mounting hole 102. The contact pin 500 includes a needle head 510 and a main body 520. The needle head 510 passes through the annular step 103. The abutment member 600 is threadedly matched with the mounting hole 102. The abutment member 600 and the annular step 103 are used to match and clamp the main body 520. The abutment member 600 can be rotated relative to the linkage member 100 to achieve compression of the contact pin 500, and the contact pin 500 can be replaced or repaired as needed.

[0051] In one embodiment, if Figure 1 , Fig.10 and Fig.11As shown, the pull-type connector further includes a fastener 700, a wire-passing hole 601 is provided in the abutment 600, and a plurality of clamping parts 610 are provided at intervals along the circumferential direction at the end of the abutment 600 away from the annular step 103. The fastener 700 is sleeved on the end of the abutment 600 away from the annular step 103, and the clamping parts 610 all extend into the fastener 700, and the inner hole diameter of the fastener 700 gradually decreases in the direction away from the annular step 103. Since there will be a wire connected to the contact pin 500, and the wire will pass through the abutment 600, the wire can pass through the wire-passing hole 601, and after the fastener 700 is sleeved, the plurality of clamping parts 610 at the end of the abutment 600 will be tightened and close to each other as the clamping parts 610 extend into the fastener 700, so as to clamp the wire, thereby achieving a good fixing effect on the wire and facilitating the removal of the contact pin 500 and the wire.

[0052] In one embodiment, if Fig.10 and Fig.11 As shown, the abutment member 600 further includes a threaded portion 620 and a stop portion 630. The threaded portion 620 is disposed on a side of the stop portion 630 away from the clamping portion 610. The threaded portion 620 is threadedly matched with the mounting hole 102. The stop portion 630 is used to abut against the handle 300. The stop portion 630 is spaced apart from the guide member 200. The stop portion 630 can limit the handle 300 and prevent the buckle body 440 on the handle 300 from falling out of the guide groove 430. No assembly is required during use, which is more convenient.

[0053] In one embodiment, if Figure 5 As shown, the distance between the two opposite side walls of the second slot section 412 gradually decreases in the direction away from the first slot section 411. The connection between the second slot section 412 and the first slot section 411 will guide the protrusion 420, so that the protrusion 420 enters the second slot section 412 from the first slot section 411. At this time, the distance between the two side walls of the second slot section 412 is large, which can prevent the protrusion 420 from being stuck at the connection, ensuring that the protrusion 420 can smoothly enter the second slot section 412 from the first slot section 411, and the distance between the two opposite side walls of the second slot section 412 decreases in the direction away from the first slot section 411. As the protrusion 420 moves, the fit between the protrusion 420 and the second slot section 412 becomes tighter, and the locking effect is better.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
