Description

Technical Field

[0001] This utility model relates to a zipper connector, belonging to the field of connector technology. Background Technology

[0002] Pull-tab connectors in related technologies typically include an insulating body, an unlocking spring mounted on the insulating body, and a pull strap that mates with the unlocking spring. The unlocking spring includes a first locking spring arm and a second locking spring arm. The pull strap directly or indirectly drives the unlocking spring to elastically deform, thereby causing the first and second locking spring arms to disengage from their locking positions, thus unlocking the mating connector.

[0003] However, the pull strap in the related technology lacks a reliable limiting structure, which makes it easy for the pull strap to deviate when pulled. This deviation may cause the pull strap to get stuck in the relevant gap, resulting in the pull strap jamming. In addition, this deviation may also cause the force applied to the unlocking spring to be not located at the center of the unlocking spring (e.g., deviated to one side), thereby causing the first locking spring arm and the second locking spring arm to fail to unlock simultaneously, resulting in unlocking failure.

[0004] There is still room for improvement in the related technology of pull strap connectors. Utility Model Content

[0046] Please refer to Figures 1 to 15 As shown, this utility model discloses a pull strap connector 100, which includes a body part 1, an unlocking spring piece 2 mounted on the body part 1, a pull strap 3 connected to the unlocking spring piece 2, and a cover plate 4 that cooperates with the unlocking spring piece 2.

[0047] In the illustrated embodiment of this utility model, the body portion 1 is provided with at least one tongue plate 11 configured to mate with a mating connector (not shown). At least one surface of the tongue plate 11 is provided with a conductive sheet 111. In the illustrated embodiment of this utility model, there are several tongue plates 11, arranged at intervals along a first direction A1-A1 (e.g., left-right direction). The width of the tongue plates 11 along the first direction A1-A1 is not uniform.

[0048] In one embodiment of this utility model, the body portion 1 includes a built-in circuit board, and the tongue plate 11 is formed from the built-in circuit board. The body portion 1 includes a cable 12 electrically connected (e.g., soldered) to the built-in circuit board.

[0049] In the embodiment illustrated in this utility model, the body portion 1 includes an insulating body 13, which has a first slot 131 and a second slot 132 arranged at intervals along the first direction A1-A1. Furthermore, the body portion 1 also includes a mounting wall 133 located at the rear end of the first slot 131 and the second slot 132. The mounting wall 133 includes a first fixing protrusion 134 and a second fixing protrusion 135. The first fixing protrusion 134 has a first retaining groove 1341 and a first pressing portion 1342 located at the top of the first retaining groove 1341. The second fixing protrusion 135 has a second retaining groove 1351 and a second pressing portion 1352 located at the top of the second retaining groove 1351.

The pull strap 3 is close to the first limiting surface 141 and the second limiting surface 151, and the pull strap 3 is limited between the first limiting surface 141 and the second limiting surface 151.

[0051] In the embodiment illustrated in this utility model, both the first limiting protrusion 14 and the second limiting protrusion 15 are integrally formed with the body portion 1. Of course, those skilled in the art will understand that the first limiting protrusion 14 and the second limiting protrusion 15 can also be designed separately from the body portion 1. In this case, the first limiting protrusion 14 and the second limiting protrusion 15 can be designed more flexibly as needed, and their materials are not necessarily the same as those of the body portion 1.

[0052] In the embodiment illustrated in this utility model, the main body 1 is further provided with a first mounting protrusion 16 and a second mounting protrusion 17, both of which cooperate with the cover plate 4. In the embodiment illustrated in this utility model, the first mounting protrusion 16 extends integrally with the first limiting protrusion 14, and the second mounting protrusion 17 extends integrally with the second limiting protrusion 15.

[0053] In the embodiment illustrated in this utility model, the main body 1 is further provided with a first fixing hole 191 and a second fixing hole 192, both of which extend along a third direction A3-A3 (e.g., vertical direction).

[0054] The pull strap 3 extends along the second direction A2-A2 (e.g., the front-to-back direction). The body portion 1 has a groove 18 that mates with the pull strap 3 and a mating surface 181 located at the bottom of the groove 18. At least a portion of the pull strap 3 extending rearward through the first limiting protrusion 14 and the second limiting protrusion 15 along the second direction A2-A2 abuts against the mating surface 181, and the mating surface 181 is flat (without steps). This configuration allows the pull strap 3 to move more smoothly when pulled by an external force, and the pull strap 3 is less prone to flipping. In the embodiment illustrated in this utility model, the first direction A1-A1, the second direction A2-A2, and the third direction A3-A3 are all perpendicular to each other.

[0055] In the embodiment illustrated in this utility model, the unlocking spring 2 is made of metal. The unlocking spring 2 includes a mounting portion 20 mounted on the body portion 1, a first bent portion 21 that bends upward and forward from one side of the mounting portion 20, a second bent portion 22 that bends upward and forward from the other side of the mounting portion 20, a middle bent portion 23 that bends upward and forward from the middle of the mounting portion 20, a force-applying portion 24 connected to the first bent portion 21, the second bent portion 22 and the middle bent portion 23, a first spring arm 25 that extends forward integrally from the force-applying portion 24, and a second spring arm 26 that extends forward integrally from the force-applying portion 24.

[0056] In the embodiment illustrated in this utility model, the mounting part 20 is provided with a first hollow hole 201, a second hollow hole 202, a first retaining part 203 located outside the first hollow hole 201, and a second retaining part 204 located outside the second hollow hole 202. The first fixing protrusion 134 is at least partially received in the first hollow hole 201, the first retaining part 203 is retained in the first retaining groove 1341, and the first pressing part 1342 presses against the first retaining part 203 along the third direction A3-A3. The second fixing protrusion 135 is at least partially received in the second hollow hole 202, the second retaining part 204 is retained in the second retaining groove 1351, and the second pressing part 1352 presses against the second retaining part 204 along the third direction A3-A3.

[0057] In the embodiment illustrated in this utility model, the mounting part 20 is attached to the mounting wall 133, and the mounting part 20 is provided with a first through hole 205 and a second through hole 206.

[0058] The first spring arm 25 is at least partially located in the first slot 131, and the second spring arm 26 is at least partially located in the second slot 132. The first spring arm 25 has a first locking protrusion 251 protruding from the body portion 1, and the second spring arm 26 has a second locking protrusion 261 protruding from the body portion 1. The first locking protrusion 251 and the second locking protrusion 261 are configured to lock with the mating connector.

[0059] In the embodiment illustrated in this utility model, the intermediate bend 23 is located between the first bend 21 and the second bend 22 along the first direction A1-A1. The intermediate bend 23 has an arc-shaped outer surface 231, and the pull strap 3 cooperates with the arc-shaped outer surface 231 to improve the stability of the pull strap 3 during sliding. The width of the intermediate bend 23 along the first direction A1-A1 is greater than the width of the first bend 21 along the first direction A1-A1, and the width of the intermediate bend 23 along the first direction A1-A1 is also greater than the width of the second bend 22 along the first direction A1-A1. With this configuration, when the pull strap 3 is pulled, the strength of the middle part of the unlocking spring 2 can be increased, preventing uneven force due to collapse and deformation at the middle part, thus preventing unlocking failure. In addition, the first bend 21 and the second bend 22 located on both sides can provide better restoring elasticity to the first spring arm 25 and the second spring arm 26 located on both sides, respectively.

[0060] In the embodiment illustrated in this utility model, the pull strap 3 is fastened to the force-applying portion 24 of the unlocking spring 2 to drive the first spring arm 25 and the second spring arm 26 to undergo elastic deformation, thereby causing the first locking protrusion 251 and the second locking protrusion 261 to disengage from the mating connector to achieve unlocking. Those skilled in the art will understand that in the embodiment illustrated in this utility model, the pull strap 3 is directly fastened to the force-applying portion 24 of the unlocking spring 2. When the embodiment illustrated in this utility model does not have a slider connected to the pull strap 3 and configured to press against the unlocking spring 2, this utility model simplifies the structure and improves reliability. In the embodiment illustrated in this utility model, when manually pressed, the hand directly presses on the unlocking spring 2.

[0061] In the embodiment illustrated in this utility model, the pull strap 3 includes a fastening part 31 that is fastened to the force-applying part 24. The portion of the pull strap 3 connected to the fastening part 31 extends out of the body part 1 from the bottom of the mounting part 20. In conjunction with the first limiting protrusion 14 and the second limiting protrusion 15 on both sides, this utility model ensures that the force exerted by the pull strap 3 on the first elastic arm 25 and the second elastic arm 26 is consistent, thereby facilitating synchronous unlocking.

[0062] In the embodiment illustrated in this utility model, the cover plate 4 is fixed to the body portion 1, and the unlocking spring 2 is at least partially located between the cover plate 4 and the body portion 1. In one embodiment of this utility model, the cover plate 4 is made of insulating material. The cover plate 4 has a first mounting hole 41 and a second mounting hole 42, the first mounting protrusion 16 is fixed in the first mounting hole 41, and the second mounting protrusion 17 is fixed in the second mounting hole 42. In one embodiment of this utility model, the first mounting protrusion 16 is fixed in the first mounting hole 41 by heat fusion, and the second mounting protrusion 17 is fixed in the second mounting hole 42 by heat fusion.

[0063] Furthermore, the cover plate 4 also includes a first opening 43 and a second opening 44. The first opening 43, the first through hole 205, and the first fixing hole 191 are aligned with each other. The second opening 44, the second through hole 206, and the second fixing hole 192 are aligned with each other. The pull strap connector 100 also includes a first fixing member 51 inserted into the first opening 43, the first through hole 205, and the first fixing hole 191 to be fixed to the body part 1, and a second fixing member 52 inserted into the second opening 44, the second through hole 206, and the second fixing hole 192 to be fixed to the body part 1. In one embodiment of this utility model, both the first fixing member 51 and the second fixing member 52 are screws.

[0064] Compared to existing technologies, the pull strap connector 100 of this utility model includes a first limiting protrusion 14 and a second limiting protrusion 15. The first limiting protrusion 14 has a first limiting surface 141 facing the second limiting protrusion 15, and the second limiting protrusion 15 has a second limiting surface 151 facing the first limiting protrusion 14. The pull strap 3 is close to the first limiting surface 141 and the second limiting surface 151, and the pull strap 3 is limited between the first limiting surface 141 and the second limiting surface 151. With this configuration, the first limiting protrusion 14 and the second limiting protrusion 15 can limit the pull strap 3, thereby preventing the pull strap 3 from getting stuck or excessively deflected, which could lead to unlocking failure.

[0065] Furthermore, even if the pull strap 3 extending from the body portion 1 deviates under force, the portion of the pull strap 3 located between the first limiting protrusion 14 and the second limiting protrusion 15 remains in a predetermined position due to the constraint of the first limiting surface 141 and the second limiting surface 151. At this time, the portion of the external force applied to the unlocking spring 2 remains in the center of the unlocking spring 2. Ultimately, the first spring arm 25 and the second spring arm 26 are evenly stressed, avoiding the problem that at least one of the first spring arm 25 and the second spring arm 26 would fail to unlock due to the deviation of the external force applied to the unlocking spring 2.

[0066] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. The understanding of the present utility model should be based on those skilled in the art. Although the present utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still make modifications or equivalent substitutions to the present utility model. All technical solutions and improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model.
