Abstract
Description
Technical Field
[0001] This utility model relates to a connector, and more particularly to a ZIF connector with anti-detachment cap. Background Technology
[0002] Zero Insertion Force (ZIF) connectors are commonly used in consumer electronics to connect internal screens, cameras, batteries, and motherboards in mobile phones, tablets, and laptops. In automotive electronics, they are used to connect in-vehicle displays, navigation systems, sensors, and other components to automotive electronic control units. In industrial automation equipment, they enable reliable connections between various circuit boards and between sensors and controllers.
[0003] With the development of technology, the technical and application requirements for zero insertion force connectors (ZIF connectors) are constantly increasing. As a result, a high-precision connector with low insertion and extraction force has emerged – the ultra-thin small-pitch ZIF connector. The thickness of this connector is usually less than 1 mm. This connector has no initial clamping force, and no force is required when inserting components. The components are fixed by activating the flip-cover clamping mechanism to achieve connection.
[0004] In the existing technology, the ZIF connector flip cover is mainly fixed by the fixing feet of the signal terminals. When the connector flip cover is flipped open and closed, it is easy to over-flip and fall off. Therefore, in the existing ZIF connector products, the flip cover lacks a reliable limiting and fixing mechanism, which cannot meet the reliability requirements of ultra-thin and small-pitch ZIF connector application scenarios. Utility Model Content
[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an anti-detachment ZIF connector, which solves the problem of the flip cover falling off of traditional ZIF connectors, and provides a reliable limiting and fixing mechanism, making the ZIF connector suitable for the needs of more application scenarios.
[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:
[0007] This utility model provides an anti-detachment ZIF connector for connecting circuit boards with lugs, characterized in that it includes a plastic body, a flip cover, a ground plate, and conductive terminals.
[0008] The plastic body has a fixing hole, a through hole, a fixing slot, a platform groove, and a locking boss on its side. The fixing hole, through hole, and fixing slot are used to fix the ground piece, and the platform groove is used to place the lug of the circuit board.
[0009] The flip cover includes a pivot protrusion and a limiting groove. The pivot protrusion and the limiting groove are distributed at both ends of the flip cover and are symmetrically arranged. The flip cover flips open and closes around the pivot protrusion.
[0010] The ground cover includes a ground cover body, a retaining part, an anti-detachment part, and a limiting part. The limiting part engages with the fixing slot. The anti-detachment part also includes a locking protrusion and a receiving groove. The locking protrusion is disposed between the anti-detachment part and the ground cover body and is used to form a limiting with the locking protrusion. The receiving groove is used to accommodate and restrict the pivot protrusion, so that the flip cover is limited in the flipping and opening direction and prevents the flip cover from falling off due to excessive flipping.
[0011] As described above, in the ZIF connector with anti-detachment cover, the ground piece body is elongated, the anti-detachment part is located between the retaining part and the limiting part, the retaining part and the limiting part are disposed at both ends of the ground piece body, the retaining part is fixed in the fixing hole, the anti-detachment part extends out from the through hole, and the limiting part is fixed in the fixing slot and extends out.
[0012] As described above, in the ZIF connector with anti-detachment cover, the anti-detachment part is an open stop ring, which is generally a ring-shaped structure containing a notch, and a receiving groove is formed in the middle of the open stop ring.
[0013] As described above, in the ZIF connector with anti-detachment cover, the limiting part is approximately "half-arc" or "U" shaped, and a fixing edge is formed in the area above the connector thickness direction, that is, above the flip cover.
[0014] As described above, in the ZIF connector with anti-detachment cover, both ends of the flip cover are provided with fixing platforms. The fixing platforms are located below the limiting grooves, and the fixing edges elastically abut against the fixing platforms, so that the flip cover is in a closed state, thereby enhancing the stability of the flip cover in the closed state.
[0015] As described above, the anti-detachment ZIF connector includes a first limiting platform and a second limiting platform, with a receiving groove formed between the first limiting platform and the second limiting platform.
[0016] As described above, in the ZIF connector with anti-detachment cover, the retaining part is generally flat, and a triangular fixing protrusion with a rounded top is provided on one side of the retaining part.
[0017] As described above, the ZIF connector with anti-detachment cover includes a plastic body that further comprises a side plate and a sloping support platform. The fixing holes, through holes, fixing slots, platform grooves, locking bosses, side plates, and sloping support platforms are symmetrically arranged at the left and right ends of the plastic body. The locking bosses are located inside the side plates of the plastic body. The ground plates are respectively fixed to the left and right ends of the plastic body.
[0018] As described above, the ZIF connector with anti-detachment cover includes a terminal hook groove located above the cover and hooked by a conductive terminal, and a rotating shaft arm located within the segment hook groove; a terminal slot for placing conductive terminals is also provided above the cover; the terminal hook groove and the terminal slot are arranged at intervals.
[0019] As described above, in the ZIF connector with anti-detachment cover, the plastic body includes multiple first terminal slots and multiple second terminal slots. The first terminal slots and the second terminal slots are respectively disposed on the front and rear sides of the plastic body. After the conductive terminals are connected to the plastic body and the flip cover, a plugging gap is formed in the middle of the conductive terminals for the circuit board to be plugged in.
[0020] The beneficial effects of this utility model are as follows: By adding a circumferential stop or upper and lower limiting structure to the ground piece to form a receiving groove, the receiving groove places and restricts the movement of the flip cover pivot protrusion, thereby limiting the upper and lower limits of the flip cover in the flip opening and closing direction; in addition, the ground piece is provided with a locking protrusion that cooperates with the locking protrusion on the plastic body to limit the movement, and the limiting part of the ground piece and the fixing slot of the plastic body form a reinforced fixation of the ground piece, making the ground piece and the plastic body more firmly connected; the addition of a limiting fixing edge on the ground piece further enhances the stability of the flip cover in the closed state.

[0038] To make the above-mentioned features and beneficial effects of this utility model more apparent and understandable, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0039] The anti-detachment ZIF connector involved in this utility model belongs to the ultra-thin, small-pitch ZIF connector category. Figure 1 and Figure 7 As can be seen, the anti-detachment ZIF connector provided by this utility model is mainly used for circuit boards 5 with lugs. The ZIF connector mainly includes a plastic body 1, a flip cover 2, a ground plate 3, and conductive terminals 4.
[0040] like Figure 1 and Figure 2As shown, the plastic body 1 is provided with a first terminal slot 106 and a second terminal slot 107, and the flip cover 2 is provided with a terminal hook slot 202, a pivot arm 203, and a terminal slot 204. The conductive terminal is provided with a first fixing arm 401, a first contact arm 402, a second fixing arm 403, a second contact arm 404, and a third fixing arm 405. The first fixing arm 401 and the second fixing arm 403 extend from the first terminal slot 106 of the plastic body 1, and the first contact arm 402, the second contact arm 404, and the third fixing arm 405 extend from the second terminal slot 107 of the plastic body 1.
[0041] In addition, the first fixing arm 401 extends out from the terminal slot 204 of the flip cover 2 and is fixed, the hook part at the end of the second fixing arm 403 hooks the flip cover 2 through the terminal hook slot 202 and the rotating shaft arm 203, and the hook part at the end of the third fixing arm 405 hooks the plastic body 1 backward. The first contact arm 402 and the second contact arm 404 are used to elastically connect the lugs to the circuit board 5.
[0042] The flip cover 2 is fixed and limited by the connecting arm of the conductive terminal, but when the flip cover 2 is flipped up excessively, there is a risk that the flip cover 2 will fall off and become displaced from below due to the lack of a limiting component or structure below.
[0043] In addition to using the aforementioned conductive terminals to restrict the flip cover 2, this utility model further provides an anti-detachment ZIF connector, which innovatively designs the plastic body 1, the flip cover 2, and the ground plate 3, thereby enabling secondary fixation and limiting of the flip cover 2 to prevent it from falling off from below.
[0044] like Figure 1 and Figure 7 As shown, the plastic body 1 is provided with a fixing hole 101, a through hole 102, a fixing slot 103, and a platform groove 104. The inner side of the side plate of the plastic body is also provided with a locking boss 105. A sloping support platform is also provided above the platform groove 104. The fixing hole 101, through hole 102, fixing slot 103, platform groove 104, side plate, locking boss 105, and sloping support platform are all symmetrically arranged at the left and right ends of the plastic body 1. The platform groove 104 is used to place the lugs of the circuit board.
[0045] Furthermore, such as Figure 4 and Figure 10 The flooring material used in this utility model includes a holding part 302, an anti-detachment part 303, and a limiting part 304. The fixing insertion hole 101, through hole 102, and fixing slot 103 of the plastic body 1 are respectively inserted into the holding part 302, anti-detachment part 303, and limiting part 304 of the flooring material 3 to fix and limit the flooring material.
[0046] In addition, the anti-detachment part 303 is also provided with a locking protrusion 303a and a receiving groove 303b. The receiving groove 303b is used to accommodate and restrict the pivot protrusion 201 on the flip cover 2. The flip cover 2 can be flipped and opened and closed around the pivot protrusion 201 in the receiving groove 303b. This restricts the flip position of the flip cover 2 and prevents the flip cover 2 from being over-flipped and causing it to become displaced and fall downward.
[0047] In addition, from Figure 3 It can be seen that the locking protrusion 303a and the locking boss 105 form a locking restriction, further limiting the position of the ground piece and promoting the ground piece's anti-detachment function to be better exerted.
[0048] Example 1:
[0049] Figure 1-7 All are ZIF connectors with anti-detachment caps provided in this embodiment. From Figure 1 and Figure 2 As can be seen, in this embodiment, the flip cover 2 of the ZIF connector also includes a pivot protrusion 201, a limiting groove 205, and a fixing platform 206 at both ends. The pivot protrusion 201 is roughly cylindrical. The groove surrounded by the three surfaces below the pivot protrusion 201 is the limiting groove 205. The fixing platform 206 in the left and right direction is also provided below the limiting groove 205, that is, on both sides below the flip cover 2.
[0050] In addition, from Figure 3 and Figure 5 The anti-detachment part 303 of the ground piece 3 provided in this embodiment includes an open stop ring 303a. The open stop ring 303a is a ring structure with a notch, which is formed by a secondary bending after the ZIF connector is assembled with the flip cover 2. The open stop ring 303a restricts the displacement or detachment of the pivot protrusion 201 from four directions: top, bottom, front, and back.
[0051] In addition, side plates are provided at both ends of the plastic body 1, which further restrict the displacement or detachment of the pivot protrusion 201 in the left and right directions. Furthermore, the opening stop ring 303a and the side plate of the plastic body 1 are connected by the pivot protrusion 201, thereby restricting the displacement or detachment of the flip cover 2 in six directions: up, down, front, back, left, and right.
[0052] like Figure 5 As shown, the limiting part 304 of the ground piece 3 provided in this embodiment is roughly "semi-arc" or "U" shaped, and a fixing edge 304a is formed above the connector thickness direction. The fixing edge 304a and the fixing platform 206 form a limiting, further restricting the flip cover 2 to be in a closed state and enhancing the stability of the flip cover 2 in the closed state.
[0053] Furthermore, the retaining part 302 is generally flat, and a triangular fixing protrusion 302a with a rounded top is provided on one side of the retaining part 302. The retaining part 302 is inserted into the fixing hole 101 and fixed in the fixing hole of the plastic body by plugging or snapping, so as to ensure a stable connection between the anti-detachment cover and the connector.
[0054] In particular, a handrail slope is provided on the inner side of the lower part of the flip cover 2, which facilitates manual opening and closing of the flip cover 2 during manual inspection and adjustment.
[0055] Example 2:
[0056] Figure 7-11 All are ZIF connectors with anti-detachment caps provided in this embodiment. From Figure 7 and Figure 9 As can be seen, in this embodiment, the flip cover 2 of the ZIF connector includes a pivot protrusion 201 and a limiting groove 205 at both ends. The pivot protrusion 201 and the limiting groove 205 are both disposed on the back of the flip cover 2, and the pivot protrusion 201 is connected to the bottom surface of the limiting groove 205. The limiting groove 205 is an open groove formed by three sides and a ground surface.
[0057] In addition, such as Figure 11 As shown, the anti-detachment part 303 of the ground piece 3 provided in this embodiment includes a first limiting platform 303d and a second limiting platform 303e. The groove formed in the middle of the first limiting platform 303d and the second limiting platform 303e is a receiving groove 303b. The receiving groove 303b is used to accommodate and restrict the pivot protrusion 201. Furthermore, the first limiting platform 303d and the second limiting platform 303e restrict the flip cover 2 from the top, bottom, and rear directions. Combined with the second fixing arm 403 restricting the flip cover 2 from the front, and the side plates provided at the left and right ends of the plastic body 1, the side plates further restrict the displacement or detachment of the pivot protrusion 201 in the left and right directions. Thus, the first limiting platform 303d, the second limiting platform 303e, the second fixing arm 403, and the side plates of the plastic body 1 combine to restrict the displacement or detachment of the flip cover 2 in six directions: top, bottom, front, rear, left, and right.
[0058] Furthermore, such as Figure 10 The retaining part 302 is generally flat, and a triangular fixing protrusion 302a with a rounded top is provided on one side of the retaining part 302. The retaining part 302 is inserted into the fixing hole 101 and fixed in the fixing hole of the plastic body by plugging or snapping, so as to ensure a stable connection between the anti-detachment cover and the connector.
[0059] In addition, a handrail slope is provided on the inner side of the lower part of the flip cover 2, which facilitates manual inspection and adjustment of the flip cover 2.
[0060] Through the above embodiments, it can be seen that in operation, the conductive terminal 4 of the ZIF connector with anti-detachment cover provided by this utility model is inserted into the two rows of terminal slots of the plastic body 1, and the two ground plates 3 are assembled on both sides of the plastic body 1. After the flip cover 2 is inserted or snapped into the conductive terminal 4 and the ground plate 1, there is a gap in the middle of the conductive terminal 4 for the lug circuit board 5 to be inserted.
[0061] like Figure 6 As shown, when the lug circuit board 5 is inserted, since there is no initial clamping force, the operator does not feel any resistance and can easily complete the insertion. After the circuit board is in place, the flip cover activates the cover lever and other pivot devices, starting the flip cover clamping mechanism to firmly fix the inserted component. The two side ground plates 3, conductive terminals 4, and plastic body 1 restrict the flip cover 2 from flipping and opening in all directions. When the flip cover is rotated to open, the circuit board ribbon cable and the terminal contacts are in close contact, ensuring stable contact and forming a stable and reliable connection.
