[0049] In addition, please combine Fig. 9 As shown, the main body 11 also includes a top surface 116, an opening 1160 that passes through the top surface 116 upward, a first mounting hole 1161 that passes through the top surface 116 upward and is located on one side of the opening 1160, and a second mounting hole 1162 that passes through the top surface 116 upward and is located on the other side of the opening 1160. The main body 11 also includes a fixing plate 117 located between the first end wall 111 and the second end wall 112. In the illustrated embodiment of the present invention, the fixing plate 117 is a vertical plate. The fixing plate 117 includes a drawstring groove 1170 that passes through the moving direction C and a drawstring shaft 1171 located between an edge (e.g., upper edge) of the fixing plate 117 and the drawstring groove 1170. The drawstring 7 extends from the connection with the movable part 3 along the moving direction C through the drawstring groove 1170, and extends out of the main body 11 after being bent around the drawstring shaft 1171. The fixing plate 117 also includes a receiving hole 1172. In the illustrated embodiment of the present invention, there are two receiving holes 1172. The receiving holes 1172 are recessed on the surface of the fixing plate 117 facing the movable part 3, that is, the receiving holes 1172 are exposed on the surface of the fixing plate 117 facing the movable part 3. One end of the elastic member 4 is disposed in the receiving hole 1172, and the other end of the elastic member 4 abuts against the movable part 3.

[0050] Please refer to Figures 4 to 6 As shown, the tongue plate 12 includes a first surface 121 and a second surface 122 that are oppositely disposed.

[0051] The conductive terminal 2 includes a docking portion 21 exposed to the tongue plate 12 and a connecting portion 22 electrically connected to the cable 5 (please refer to FIG. Fig. 9As shown). In the illustrated embodiment of the present invention, the docking portion 21 is in the shape of a flat plate and is exposed on the first surface 121 and the second surface 122, respectively. In one embodiment of the present invention, the conductive terminal 2 is embedded in the insulating body 1. Of course, in other embodiments, the conductive terminal 2 can also be directly installed on the insulating body 1; or the conductive terminal 2 and the insulating block are first combined into a terminal module and then installed on the insulating body 1. The fixing method of the conductive terminal 2 and the insulating body 1 is well known to those skilled in the art, and the present invention will not be repeated.

[0052] In the illustrated embodiment of the present invention, the cable 5 extends beyond the main body 11 along the moving direction C.

In the illustrated embodiment of the present invention, there are two first locking protrusions 311 and they are respectively located on both sides (e.g., the left side and the right side) of the base 31 to improve the docking retention force. In the illustrated embodiment of the present invention, the first locking protrusion 311 is integrally formed with the main body 11. Of course, in other embodiments, the first locking protrusion 311 can also be made separately from the main body 11 and then assembled and fixed together. In this case, the first locking protrusion 311 can be made of a material different from that of the main body 11, such as a wear-resistant material with good structural strength. The base 31 is also provided with a drawstring connection portion 312, and the drawstring 7 is connected to the drawstring connection portion 312. The drawstring connection portion 312 includes a through groove 310 that penetrates the base along the moving direction C. The drawstring connection portion 312 is located above the through groove 310. The drawstring connecting portion 312 is similar to an axle and is located between the through slot 310 and an edge (eg, upper edge) of the base 31. One end of the drawstring 7 passes through the through slot 310 and is sleeved around the drawstring connecting portion 312.

[0055] In the illustrated embodiment of the present invention, the elastic member 4 is a compression spring installed between the base 31 and the inner wall surface 115 of the main body 11. There are two compression springs arranged side by side to improve the stability of the movable part 3 when moving. In addition, in order to better position the compression spring, the base 31 is also provided with a positioning column 313 (see FIG. 1 ) which is at least partially inserted into the compression spring. Fig.11 shown).

[0056] The drawstring connector 100 includes a second locking protrusion 14 that protrudes backward from the second end wall 112. In the illustrated embodiment of the present invention, there are two second locking protrusions 14 and they are located on both sides (e.g., the left side and the right side) of the second end wall 112 to improve the docking retention force. In the illustrated embodiment of the present invention, the second locking protrusion 14 is integrally formed with the main body 11 to save costs. Of course, in other embodiments, the second locking protrusion 14 can also be made separately from the main body 11 and then assembled and fixed together. In this case, the second locking protrusion 14 can be made of a different material from the main body 11. The first locking protrusion 311 and the second locking protrusion 14 are used to snap with the locking hole of the docking connector 200 to improve the docking retention force (to be described in detail later).

[0057] Please refer to Figure 7 , Figure 8 and Fig.11 As shown, the first push rod 32 includes a first groove 320, a first limiting surface 321 located at one end of the first groove 320 along the moving direction C, and a second limiting surface 322 located at the other end of the first groove 320 along the moving direction C. The first limiting surface 321 is closer to the first end wall 111 than the second limiting surface 322.

[0058] Similarly, the second push rod 33 includes a second groove 330, a third limiting surface 331 located at one end of the second groove 330 along the moving direction C, and a fourth limiting surface 332 located at the other end of the second groove 330 along the moving direction C.

[0059] The drawstring connector 100 includes a first pin 151 and a second pin 152 fixed in the first mounting hole 1161 and the second mounting hole 1162. The first pin 151 is inserted into the first groove 320, and the second pin 152 is inserted into the second groove 330. The size of the first groove 320 along the moving direction C is larger than the size of the first pin 151 along the moving direction C. The size of the second groove 330 along the moving direction C is larger than the size of the second pin 152 along the moving direction C. The first limiting surface 321 is used to abut against the first pin 151, and the third limiting surface 331 is used to abut against the second pin 152, so as to prevent the movable component 3 from excessively moving along the moving direction C under the action of the pull belt 7; the second limiting surface 322 is used to abut against the first pin 151, and the fourth limiting surface 332 is used to abut against the second pin 152, so as to prevent the movable component 3 from excessively returning in the direction opposite to the moving direction C when the elastic member 4 releases the restoring force.

[0060] The cover plate 6 is received and fixed in the opening 1160 of the main body 11, and the drawstring 7 extends out of the cover plate 6. In one embodiment of the present invention, the cover plate 6 presses the connection between the cable 5 and the conductive terminal 2 (for example, the welding part between the two) to play a protective role.

[0061] Please refer to Figures 2 to 7 as well as Fig.12 As shown, the docking connector 200 includes a docking insulating body 81, a plurality of docking terminals 82 fixed on the docking insulating body 81, and a metal shell 83 covering the docking insulating body 81. The docking insulating body 81 includes a bottom wall 811 and a plurality of side walls 812 perpendicular to the bottom wall 811. Figure 5 As shown, the bottom wall 811 is provided with a positioning groove 8110 for accommodating the positioning plate 13. Specifically, the positioning groove 8110 includes a first positioning groove 8111 for accommodating the first positioning piece 131, a second positioning groove 8112 for accommodating the second positioning piece 132, and a third positioning groove 8113 for accommodating the third positioning piece 133. In the illustrated embodiment of the present invention, the first positioning groove 8111, the second positioning groove 8112, and the third positioning groove 8113 pass through the bottom wall 811.

[0062] Please refer to Figure 7 and Fig.12As shown, the side walls 812 enclose a docking slot 8120 for accommodating the tongue plate 12. The docking terminals 82 are arranged in two rows, and the docking terminals 82 include elastic docking arms 821 and mounting tails 822 for mounting on the circuit board 300. The elastic docking arms 821 extend into the docking slot 8120 and are used to contact the docking portion 21.

[0063] The metal shell 83 includes a first side wall 831, a second side wall 832 arranged opposite to the first side wall 831, a first connecting wall 833 connecting one side of the first side wall 831 and one side of the second side wall 832, and a second connecting wall 834 connecting the other side of the first side wall 831 and the other side of the second side wall 832. The first side wall 831 is provided with a first locking hole 8311 matched with the first locking protrusion 311. The second side wall 832 is provided with an elastic arm 8321, and the elastic arm 8321 is provided with a second locking hole 8322 matched with the second locking protrusion 14. In the illustrated embodiment of the present invention, the elastic arm 8321 is a cantilever, which can be elastically deformed under the action of an external force and return to its original position after the external force is released. In the illustrated embodiment of the present invention, there are two elastic arms 8321, which are respectively located on the left and right sides of the second side wall 832, wherein the elastic arm 8321 close to the first connecting wall 833 has a first slot 8323 therebetween and the first connecting wall 833, and the elastic arm 8321 close to the second connecting wall 834 has a second slot 8324 therebetween and the second connecting wall 834 (please refer to FIG. Figure 3 By providing the first slot 8323 and the second slot 8324, the corresponding elastic arm 8321 has better elastic deformation ability.

[0064] When the pull-tab connector 100 is inserted into the docking connector 200, the positioning plate 13 corresponds to the positioning groove 8110, the tongue plate 12 corresponds to the docking slot 8120, and the docking portion 21 of the conductive terminal 2 corresponds to the elastic docking arm 821 of the docking terminal 82; as the pull-tab connector 100 is inserted, the inclined surfaces of the first locking protrusion 311 and the second locking protrusion 14 respectively abut against the first side wall 831 and the second side wall 832; the movable component 3 overcomes the action of the elastic member 4 and shrinks inwardly along the moving direction C by a certain distance; when the first locking protrusion 311 and the second locking protrusion 14 move downward to correspond to the first locking hole 8311 and the second locking hole 8322, the elastic member 4 restores the elastic force to make the movable component 3 return to its position in the direction opposite to the moving direction C. At this time, the first locking protrusion 311 and the second locking protrusion 14 protrude forward and backward into the first locking hole 8311 and the second locking hole 8322 respectively, so as to realize the locking of the drawstring connector 100 and the docking connector 200. Compared with the prior art, the present invention can realize double-sided locking by providing the first locking protrusion 311 and the second locking protrusion 14 on both sides, thereby improving the docking retention force and reducing the risk of the drawstring connector 100 and the docking connector 200 becoming loose.

[0065] When unlocking is required, an external force is applied to pull the drawstring 7, and the drawstring 7 generates a force component along the moving direction C, which overcomes the force of the elastic member 4, so that the movable component 3 moves along the moving direction C; at this time, on the one hand, the first locking protrusion 311 is disengaged from the first locking hole 8311; on the other hand, the first push rod 32 and the second push rod 33 extend rightward and protrude from the second end wall 112 to push the corresponding elastic arm 8321 to deform outward, so that the second locking protrusion 14 is disengaged from the second locking hole 8322. In other words, at this time, the drawstring connector 100 and the docking connector 200 are unlocked on both sides, and the drawstring connector 100 can be pulled out of the docking connector 200 by applying other forces or by applying an upward force component on the drawstring 7.

[0066] The above implementation modes are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. The understanding of the present invention should be based on the technical personnel in the relevant technical field. Although the present invention has been described in detail in this specification with reference to the above implementation modes, the ordinary technical personnel in the field should understand that the technical personnel in the relevant technical field can still modify or replace the present invention with equivalents, and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention.
