Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a ZIF connector device. Background Art

[0002] Electronic products are generally composed of a combination of many electronic modules assembled and connected. For example, a mobile phone is composed of a screen module, camera module, button module, audio module, antenna module, battery module, fingerprint module, charging module, etc., as well as a circuit board containing various chips, forming a complete mobile phone circuit.

[0003] As the name suggests, connectors are devices that connect modules together. For example, a display module is electrically connected to a circuit board through a connector. A ZIF connector is a type of connector; it's typically used with FPC boards.

[0004] Figure 1 This is a ZIF connector in the prior art, comprising a main body a, one end of which is recessed inward to form a slot, a resilient terminal b disposed on the bottom surface of the slot, and a locking structure c disposed on the main body a. When in use, the ZIF connector is soldered to the circuit board via SMT soldering. When connecting to an FPC board d, the FPC board is typically manually inserted into the slot, and the locking structure c is then used to position and secure the FPC board in place. The resilient terminal b is then used to establish contact and conduction with the circuitry on the FPC board, thereby completing the electrical connection. Figure 2 shown.

[0005] When manually inserting the FPC board, you first need to align the end of the FPC board with the opening of the slot b. The FPC board needs to be inserted into the slot b from the side. Since both sides of the main part a are in an unlimited position (such as Figure 3 As shown), the visual positioning effect is poor, and it is not easy to align and insert at one time. At the same time, due to the lack of support at the bottom of slot b, the end of the FPC board will be in a suspended state during alignment (as shown Figure 4 Manual operation is prone to jitter, which can cause assembly collisions during the insertion process, resulting in problems such as FPC board damage, FPC board bending, and damage to the module or ZIF connector. To reduce the probability of assembly collisions during FPC board insertion, current solutions mostly reduce assembly speed, but this cannot achieve a lossless assembly process and directly leads to reduced production line capacity and efficiency, thereby increasing manufacturing costs.

[0006] Based on this, the present invention provides a ZIF connector device to solve the above-mentioned problems. Utility Model Content

[0009] Furthermore, the bottom plate is formed by extending the bottom of the ZIF connector body, the two side plates are formed by extending the two side edges of the ZIF connector body respectively, and the two side plates have guiding inclined surfaces.

[0010] Furthermore, the guiding inclined surface is connected to the side wall of the slot of the ZIF connector body, and the guiding inclined surface is inclined toward the outside of the slot of the ZIF connector body.

[0011] Furthermore, the guiding inclined surface is connected to the slot side wall of the ZIF connector body by using a first arc surface.

[0013] Furthermore, the surface roughness Ra of the end face of the bottom plate close to the slot of the ZIF connector body ranges from 0.05 μm to 0.1 μm.

[0023] The following is a more detailed description of the ZIF connector device of the present invention, with reference to schematic diagrams, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention as described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0024] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0025] like Figure 5 As shown, an embodiment of the present invention proposes a ZIF connector device, including a ZIF connector body 1; a support guide structure 2 is provided at the slot opening end of the ZIF connector body 1, and the support guide structure is "U"-shaped, including a bottom plate 21 and side plates 22 located on both sides of the bottom plate 21, and the inner end surface of the support guide portion is used for bottom support and guidance when the FPC board is plugged in, and the two inner side walls of the support guide structure are used for side limiting and guiding when the FPC board is plugged in.

[0026] In the above embodiment, the connector body 1 is fixed to the corresponding position of the circuit board by SMT welding, and the side panels 22 of the two side parts of the support and guide structure 2 are respectively located on both sides of the slot opening end of the ZIF connector body 1, and the inner end surface of the bottom plate 21 of the support and guide structure 2 is flush with the bottom surface of the slot opening end of the ZIF connector body 1.

[0027] When the FPC board is plugged in, the inner side walls of the two side plates 22 of the support guide structure 2 can provide guide limits for both sides of the slot of the ZIF connector body 1 (such as Figure 6 As shown), compared with the existing technology, the visual positioning effect is optimized and the success rate of one-time insertion is improved. At the same time, the inner end surface of the bottom plate of the support and guide structure 2 can support and guide the FPC board (as shown). Figure 7 As shown), this can solve the problem of FPC board hanging plug-in, and compared with the existing technology, it obviously reduces the occurrence of assembly collision.

[0028] In summary, the ZIF connector device provided in this embodiment provides a "U"-shaped support and guide structure 2 at the slot opening end of the ZIF connector body 1 to provide bottom support and guidance and two-side limiting and guidance for the FPC board before plugging in, thereby effectively reducing the probability of assembly collision of the FPC board during plug-in assembly, while improving assembly efficiency and fundamentally reducing manufacturing costs.

[0029] In the above embodiment, the bottom plate 21 is formed by extending the bottom of the ZIF connector body 1. When assembling the FPC board, the bottom plate 21 fits the FPC board to provide bottom support and guidance for the FPC board before insertion.

[0030] Preferably, the surface roughness Ra of the end face of the base plate 21 close to the slot of the ZIF connector body 1 is in the range of 0.05μm-0.1μm, ensuring that the contact surface between the base plate 21 and the FPC board has better smoothness, that is, ensuring that there is a reasonable friction coefficient between the base plate 21 and the FPC board, avoiding scratches on the FPC board due to excessive friction coefficient or affecting the smoothness of the FPC board when plugging in.

[0031] The two side panels 22 are respectively extended from the two side edges of the ZIF connector body 1 , and both side panels 22 have guiding slopes 221 . When assembling the FPC board, the guiding slopes 221 provide positioning and guidance for the side edges of the FPC board.

[0032] Specifically, the guiding inclined surface 221 is connected to the side wall of the slot of the ZIF connector body 1 , and the guiding inclined surface 221 is inclined toward the outside of the slot of the ZIF connector body 1 .

[0033] Furthermore, the guiding bevel 221 is connected to the slot sidewall of the ZIF connector body 1 by a first arc surface 222, and the end of the guiding bevel 221 away from the ZIF connector body 1 has a second arc surface 223. The provision of the first arc surface 222 and the second arc surface 223 effectively avoids the risk of damage to the FPC board due to collision with sharp corners during insertion.

[0034] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
