Description

Technical Field

[0001] The utility model belongs to the technical field of shrapnel, and particularly relates to a double-line clip double-contact shrapnel. Background Art

[0002] In modern electronic communication devices, shrapnel and wire clips play a crucial role. As the link for signal transmission, shrapnel is not only responsible for the transmission between the antenna signal, electronic components and the main board, but also undertakes the contact function with the middle frame or the rear shell to ensure stable and efficient signals. The wire clip, on the other hand, is a solid support for the coaxial cable to be fixed and routed on the PCB board. Especially for the coaxial cable with a grounding ring, the wire clip plays an indispensable grounding role to ensure the electromagnetic compatibility and safety of the device.

[0003] However, with the rapid progress of technology and the market's pursuit of ultra-thin and miniaturized electronic devices, the design of traditional shrapnel and wire clips faces unprecedented challenges. Limited by the limited space of the mobile phone main board, how to further reduce the external dimensions of components while meeting the requirements of ultra-thinness has become an urgent problem to be solved. In addition, consumers' diverse demands for product functions and expectations for cost control also pose higher requirements for the design of shrapnel and wire clips.

[0004] Traditional shrapnel and wire clips, due to their large external dimensions and independent monomer structures, not only occupy too much internal space of the main board, but also require two sets of molds to achieve production, which undoubtedly increases costs and reduces efficiency. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sunken plate type, low working height, ultra-thin, double-line clip double-contact combined shrapnel to solve the deficiencies of the prior art.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A double-line clip double-contact shrapnel includes: a substrate, the front and rear ends of the substrate extend outward and bend obliquely upward to form contact arms for elastic contact with external electronic components, the left and right ends of the substrate extend outward and bend downward to form extension arms, and the ends of the extension arms are turned outward to form wire clip claws capable of clamping and fixing the coaxial cable.

[0008] Further, the bottom surface of the substrate is a welding surface.

[0009] Further, the end of the contact arm bends outward to form an arc-shaped contact part with a radian.

[0010] Further, convex bumps protruding upward are provided on the arc-shaped contact part of the contact arm.

[0011] Further, the wire clamping jaws are perpendicular to the substrate.

[0012] Further, the opening of the wire clamping jaws is smaller than the outer diameter of the coaxial cable to ensure the clamping force.

[0013] Further, the ends of the wire clamping jaws are bent outward to form arc-shaped guiding portions with arcs.

[0014] Further, the two contact arms are symmetrically arranged in front and back mirror images with the center of the substrate as the reference.

[0015] Further, the two wire clamping jaws are symmetrically arranged in left and right mirror images with the center of the substrate as the reference.

[0016] Compared with the prior art, the beneficial technical effects are as follows:

[0017] The double wire clamp and double contact elastic sheet provided by the present utility model adopts an integrated design. After the elastic sheet is welded, the wire clamp part sinks to the bottom of the board, which can effectively reduce the space occupied by the elastic sheet on the PCB, realizing ultra-thinness and miniaturization. On the premise of ensuring functionality, only one set of molds can be used to realize the original two products, greatly reducing the mold and stamping equipment costs, simplifying the product process, and at the same time greatly improving the stamping and SMT production efficiency, meeting the dual requirements of the market for multi-functionality and cost-effectiveness.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0027] The embodiment of the present invention provides a double-line clip and double-contact elastic sheet, including: a substrate 1, a contact arm 2, an extension arm 3, and a line clip claw 4. The double-line clip and double-contact elastic sheet provided by the present invention is integrally bent from a 0.08 mm ultra-thin material (33.4% thinner than the traditional line clip), reducing the yield of the force arm and greatly improving the elasticity stability and service life. It realizes the stamping of two original products with one set of molds, simplifies the process, and can complete the installation of two major functional components with one-time chip mounting, improving production efficiency and reducing production costs. Specifically:

[0028] As Figures 1 to 5 shown, in this embodiment, the bottom surface of the substrate 1 is a welding surface 101 to weld and fix the substrate 1 to the PCB board. The contact arm 2 is used for elastic contact with external electronic components. The contact arm 2 extends outward from the front and rear ends of the substrate 1 and bends obliquely upward. The two contact arms 2 are symmetrically arranged front and rear with the center of the substrate 1 as the reference, forming a double-wing elastic sheet with double contacts, providing circuit connection through two independent contact points, which can effectively increase the stability and reliability of the connection. The end of the contact arm 2 bends downward to form an arc-shaped contact part 201 with a certain radian, and an upward convex bump 202 is also stamped on the arc-shaped contact part 201 of the contact arm 2, so that the elastic sheet can more effectively transmit the contact force and ensure good electrical contact.

[0029] In this embodiment, the extension arm 3 extends outward from the left and right ends of the substrate 1 and bends vertically downward. The end of the extension arm 3 turns outward to form a line clip claw 4 that can clamp and fix the coaxial cable, and the two line clip claws 4 are symmetrically arranged left and right with the center of the substrate 1 as the reference. After the substrate 1 is welded, the extension arm 3 can pass through the PCB board and sink to the bottom of the board, thus saving the working height and the board occupation area while realizing functional diversification. Ensure that the theoretical minimum working height of the double-line clip and double-contact elastic sheet after product welding can reach 0.20 mm, meeting the customer's usage requirements for miniaturization and ultra-thinness.

[0030] Further, to ensure the insertion force / extraction force when engaging with the coaxial cable and the forward force when compressed to the working state, and to prevent the coaxial cable from loosening, according to the dimensions of the coaxial cable, the wire clamp jaw 4 is designed with a constricted opening (i.e., the opening of the wire clamp jaw 4 is smaller than the outer diameter of the coaxial cable) to ensure the clamping force. Moreover, the end of the wire clamp jaw 4 is bent outwardly in the reverse direction with a certain arc to form an arc-shaped guiding portion 401. On the one hand, it can facilitate the pressing of the coaxial cable into the clamping opening of the wire clamp jaw 4, and on the other hand, it can prevent the burrs at the edge of the end of the wire clamp jaw 4 from piercing the flexible wire and causing functional failure of the coaxial cable.

[0031] The above-described embodiments only represent the implementation modes of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the appended claims.
