Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a zipper connector and connector assembly. Background Technology

[0002] The pull strap connector is used to mate with the mating connector. The locking element is located on the insulating part of the pull strap connector and is used to lock the pull strap connector and the mating connector. By pulling the pull strap on the locking element, the locking element is disengaged from the mating connector, thereby unlocking the pull strap connector and the mating connector.

[0003] In related technologies, the locking element is equipped with a spring piece, which is a barbed anti-retraction structure used to form a one-way engagement with the insulating component. When the pull strap is pulled, the pull strap drives the locking element to move, thereby disengaging the locking element from the mating connector. However, the barbed anti-retraction spring piece has low strength. After the pull strap connector is subjected to vibration or long-term use, the spring piece is prone to deformation, fatigue, or even breakage, leading to loosening or failure of the connection between the locking element and the insulating component. Utility Model Content

[0004] The purpose of one embodiment of this utility model is to provide a pull strap connector and connector assembly, which improves the resistance of the spring to deformation, fatigue and fracture, and improves the connection reliability between the locking component and the insulating component.

[0005] One embodiment of this utility model adopts the following technical solution:

[0006] A zipper connector, comprising:

[0007] Insulating components are equipped with locking grooves;

[0008] A locking element is provided on the insulating element. The locking element is provided with a spring piece. One end of the spring piece along the first direction is connected to the locking element, and the other end is suspended. The spring piece is locked in the locking groove along the second direction. The first direction and the second direction are set at an angle, and the angle is greater than 0 and less than 180°.

[0010] In some embodiments, the angle between the first direction and the second direction is 90°, and the side of the spring piece along the second direction is in contact with the groove wall of the locking groove.

[0011] In some embodiments, the spring includes a first elastic portion and a second elastic portion arranged along a first direction and disposed at an angle, the first elastic portion being connected between the second elastic portion and the locking member, and the second elastic portion being capable of deforming relative to the first elastic portion to be located within the locking groove.

[0012] In some embodiments, the insulating member is provided with a clearance groove communicating with the latch groove, and the connection between the first elastic part and the second elastic part is not lower than the first groove bottom of the clearance groove.

[0013] In some embodiments, the insulating member is provided with at least two locking slots, the locking member is provided with at least two spring pieces, the at least two spring pieces are locked in the at least two locking slots in a one-to-one correspondence, the at least two locking slots are arranged along the first direction, and the at least two spring pieces are arranged in a corresponding manner along the first direction.

[0014] In some embodiments, the locking member is inserted into the insulating member along the second direction. One of the insulating member and the locking member has a first limiting groove, and the other has a first limiting platform. The first limiting platform is located within the first limiting groove, thereby limiting the insulating member and the locking member along the first direction. And / or, one of the insulating member and the locking member has a second limiting groove, and the other has a second limiting platform. The second limiting platform is located within the second limiting groove, thereby limiting the insulating member and the locking member along a third direction, which is perpendicular to both the first direction and the second direction.

[0015] In some embodiments, the locking member is U-shaped and includes a first sidewall and a second sidewall that are spaced apart and connected to each other along a third direction. The second sidewall is located on the side of the first sidewall away from the insulating member. The spring is located on the first sidewall. The second sidewall has a latching protrusion for engaging with the slot of the mating connector.

[0016] In some embodiments, the second sidewall is provided with an avoidance window, and the projection of the spring sheet on the second sidewall is located within the avoidance window.

[0017] In some embodiments, the insulating member is provided with a baffle, and when the mating connector is inserted into the pull strap connector, the baffle abuts against the side of the mating connector where the slot is provided.

[0018] A connector assembly includes a mating connector and a zipper connector as described in any of the preceding claims, the mating connector being inserted into the zipper connector.

[0019] The beneficial effects of this utility model embodiment:

[0020] One embodiment of this utility model provides a pull tab connector and connector assembly. The direction of the tension force on the spring tab is angled to the extension direction of the spring tab. That is, the extension direction of the spring tab experiences the component of the tension force, and the width direction of the spring tab also experiences the component of the tension force. The side of the spring tab contacts the wall of the locking groove to bear pressure, relying on the lateral stiffness of the spring tab to prevent slippage. This reduces the force on the extension direction of the spring tab, effectively improving its resistance to deformation, fatigue, and fracture, and enhancing the connection reliability between the locking component and the insulating component. Furthermore, the angled locking direction of the spring tab to its extension direction helps to shorten the space occupied by the spring tab in the second direction, facilitating the miniaturization design of the pull tab connector.

[0035] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0038] In related technologies, the spring clip adopts a barbed anti-retraction structure. The end of the spring clip that connects to the locking element is the root, and the other end is the elastic end. The elastic end of the spring clip is used to form a one-way engagement with the insulating element by relying on the elastic deformation of the spring clip. When the pull strap pulls the locking element, the direction of the tension force of the pull strap on the spring clip is the extension direction of the spring clip. The root of the spring clip is subjected to bending stress and shear stress, which can easily lead to failures such as deformation, fatigue or breakage.

[0039] like Figures 1-9 As shown, this embodiment provides a pull strap connector, including an insulating member 100, a locking member 200, and a pull strap 300. The insulating member 100 is provided with a locking groove 110. The locking member 200 is disposed on the insulating member 100 and is provided with a spring piece 210. One end of the spring piece 210 along a first direction is connected to the locking member 200, and the other end is suspended. The spring piece 210 is locked in the locking groove 110 along a second direction. The first direction and the second direction are set at an angle, and the angle range is greater than 0 and less than 180°. One end of the pull strap 300 along the second direction is connected to the locking member 200, and the other end is located outside the locking member 200.

[0040] The tension direction of the spring piece 210 is set at an angle to the extension direction of the spring piece 210, meaning that the extension direction of the spring piece 210 is subjected to the component of the tension force, and the width direction of the spring piece 210 is also subjected to the component of the tension force. The side of the spring piece 210 contacts the groove wall of the locking groove 110 to bear pressure, relying on the lateral stiffness of the spring piece 210 to prevent slippage. This reduces the force on the spring piece 210 in the extension direction, effectively improving its resistance to deformation, fatigue, and fracture, and enhancing the connection reliability between the locking element 200 and the insulating element 100. Furthermore, the locking direction of the spring piece 210 is set at an angle to its extension direction, which helps to shorten the space occupied by the spring piece 210 in the second direction, facilitating the miniaturization design of the pull-tab connector.

[0041] In one embodiment, the angle between the first direction and the second direction is 90°. The side of the spring piece 210 along the second direction is in contact with the groove wall of the locking groove 110. The tension of the spring piece 210 in the extending direction caused by the pull strap 300 is zero, and the pressure is entirely borne by the contact between the side of the spring piece 210 and the groove wall of the locking groove 110, making the anti-retraction force of the spring piece 210 more stable. The space occupied by the spring piece 210 in the second direction is the width of the spring piece 210, making the size of the pull strap connector in the second direction as small as possible. The side of the spring piece 210 and the groove wall of the locking groove 110 make surface contact, which effectively improves the assembly accuracy of the locking component 200 and the insulating component 100.

[0042] The spring piece 210 includes a first elastic portion 211 and a second elastic portion 212 arranged along a first direction and at an included angle. The first elastic portion 211 is connected between the second elastic portion 212 and the locking member 200. The second elastic portion 212 can deform relative to the first elastic portion 211 to be located within the locking groove 110. During assembly, the locking member 200 is mounted on the insulating member 100, and the spring piece 210 is correspondingly positioned in the locking groove 110. Then, the second elastic portion 212 is riveted to position it within the locking groove 110. By performing these two steps, the second elastic portion 212 is installed into the locking groove 110, facilitating assembly and reducing the possibility of elastic deformation, fatigue, and breakage at the root of the spring piece 210 during assembly. After riveting, the bottom of the second elastic portion 212 is parallel to the second groove bottom 111 of the locking groove 110, with a gap between them or they may abut against each other.

[0043] The insulating component 100 is provided with a relief groove 120 that communicates with the locking groove 110. The connection 213 of the first elastic part 211 and the second elastic part 212 is not lower than the first groove bottom 121 of the relief groove 120. During assembly, the connection 213 passes through the first groove bottom 121 of the relief groove 120 and then moves to the locking groove 110 to prevent structural interference and facilitate assembly.

[0044] In one embodiment, the locking member 200 is U-shaped and includes a first sidewall 240 and a second sidewall 250 that are spaced apart and connected to each other along a third direction. The second sidewall 250 is located on the side of the first sidewall 240 away from the insulating member 100. A spring piece 210 is located on the first sidewall 240. The third direction is perpendicular to the first and second directions. Exemplarily, the third direction is a vertical direction, and the first and second directions are horizontal directions. The second sidewall 250 is located above the first sidewall 240 and is used to lock with the mating connector. The end of the second sidewall 250 away from the connection with the first sidewall 240 is provided with a through hole 270, through which the pull strap 300 passes to connect with the locking member 200.

[0045] The insulating component 100 has at least two locking slots 110, and the locking component 200 has at least two spring tabs 210, that is, the first sidewall 240 has at least two spring tabs 210. The at least two spring tabs 210 are locked one-to-one with the at least two locking slots 110. By increasing the number of locking slots 110 and corresponding spring tabs 210, the connection reliability between the insulating component 100 and the locking component 200 is improved. However, if the number of locking slots 110 and spring tabs 210 is too large, the structure will be more complex, occupy more space, and be difficult to arrange. For example, there can be two, three, four or more locking slots 110, and correspondingly two, three, four or more spring tabs 210.

[0046] At least two locking slots 110 are arranged along the first direction, and at least two spring pieces 210 are correspondingly arranged along the first direction, thereby reducing the size of the pull strap connector along the second direction. Alternatively, at least two locking slots 110 are arranged along the second direction, and at least two spring pieces 210 are correspondingly arranged along the second direction. Alternatively, the locking slots 110 can be arranged arbitrarily, and the spring pieces 210 can be arranged accordingly.

[0047] For example, two springs 210 are provided, and the second elastic portions 212 of the two springs 210 are arranged facing or away from each other along the first direction. By providing two springs 210 and corresponding two locking grooves 110, the connection reliability between the insulating member 100 and the locking member 200 can be satisfied without making the structure too complicated.

[0048] The locking element 200 is inserted into the insulating element 100 along the second direction. One of the insulating element 100 and the locking element 200 has a first limiting groove 220, and the other has a first limiting platform 130. The first limiting platform 130 is positioned within the first limiting groove 220, thus limiting the insulating element 100 and the locking element 200 along the first direction and improving their installation accuracy. Alternatively, one of the insulating element 100 and the locking element 200 has a second limiting groove 140, and the other has a second limiting platform 230. The second limiting platform 230 is positioned within the second limiting groove 140, thus limiting the insulating element 100 and the locking element 200 along a third direction. This third direction is perpendicular to both the first and second directions, further improving the installation accuracy of the locking element 200 and the insulating element 100 along this third direction.

[0049] For example, the first direction is the left-right direction, the second direction is the front-back direction, the pull strap 300 is located on the front side of the pull strap connector, the first sidewall 240 and the second sidewall 250 are connected on the rear side of the locking member 200, the first sidewall 240 and the second sidewall 250 are provided with a first limiting groove 220 on the rear side, and the insulating member 100 is provided with a first limiting platform 130 on the rear side; the first sidewall 240 is provided with a second limiting platform 230 on the rear side, and the insulating member 100 is provided with a second limiting groove 140 with the groove opening facing the front side; and / or, the first sidewall 240 is provided with a second limiting platform 230 on the left and right sides, and the insulating member 100 is provided with a second limiting groove 140 with the groove opening facing the front side. The locking element 200 is inserted into the insulating element 100 from front to back, so that the second limiting platform 230 is inserted into the second limiting groove 140 and the first limiting platform 130 is inserted into the first limiting groove 220. After being inserted into place, the spring piece 210 is located at the locking groove 110, which facilitates assembly.

[0050] The second sidewall 250 is provided with a clearance window 280. The projection of the spring piece 210 on the second sidewall 250 is located in the clearance window 280, so as to facilitate observation of the spring piece 210 being installed in the locking groove 110 and the second elastic part 212 being riveted through the clearance window 280.

[0051] The locking member 200 has a latching protrusion 260, specifically a latching protrusion 260 on the second sidewall 250, for engaging with the slot of a mating connector (such as a wire connector). Specifically, the mating connector has a housing, and the slot is formed on the housing. When the mating connector and the pull strap connector are inserted, the housing is inserted into the pull strap connector, and the locking member 200 is located inside the housing. The slot and the latching protrusion 260 on the housing engage. However, when the pull strap connector is subjected to strong tension, the latching protrusion 260 can easily deform the housing of the mating connector, causing the latching protrusion 260 to disengage from the slot and fail to engage. Therefore, the insulating member 100 has a stop 150. When the mating connector and the pull strap connector are inserted, the stop 150 abuts against the side of the mating connector with the slot. The stop 150 can prevent deformation of the housing, thereby preventing the latching protrusion 260 from disengaging from the slot and improving the connection reliability of the pull strap connector and the mating connector.

[0052] The pull-tab connector includes electrical components 400, such as conductive terminals, for electrical connection with the mating connector. This is based on existing technology and will not be elaborated further. The insulating component 100 is a housing located outside the electrical components 400, providing support and protection for the electrical components 400.

[0053] This embodiment also provides a connector assembly, including a mating connector and a pull strap connector as described above. The mating connector is inserted into the pull strap connector. By improving the resistance of the spring piece 210 of the pull strap connector to deformation, fatigue and fracture, the connection reliability between the locking member 200 and the insulating member 100 is improved, the reliability of the pull strap connector is improved, and thus the reliability of the connector assembly is improved.

[0054] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
