Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to an LGA connector structure. Background Technology
[0002] In the field of electronic product manufacturing, especially in modules involving high-frequency signal transmission, it is often necessary to fix and connect terminals (such as grounding terminals or signal transmission terminals) to plastic structural components.
[0003] Currently, adjacent LGA contact terminals in CPU / CPO Socket are all of independent structure. Each LGA contact terminal is set separately in a corresponding terminal receiving slot, with both ends of the LGA contact terminal protruding outside the terminal receiving slot for contact with other components.
[0004] However, the existing LGA contact terminal structure design is flawed. Because the two ends of each terminal have different structures for contacting other components, the installation direction of each terminal needs to be distinguished during the assembly of each terminal into the terminal receiving slot. Otherwise, the LGA contact terminal will be installed backwards, resulting in the need for rework of the reversed products. This makes assembly inconvenient, reduces the production efficiency of the products, fails to meet the user's needs, and has a limited range of applications.
[0005] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content
[0006] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide an LGA connector structure that utilizes the symmetrical one-piece molding of the upper and lower contact sections of the terminals, eliminating the need to distinguish the orientation of the terminals during assembly, thus ensuring the assembly quality of the product and improving the SI performance of the product. At the same time, the setting of two fixing films strengthens the fixing and protection effect of the two ends of the terminal module on the mounting groove, thereby improving the stability of the product in use.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: An LGA connector structure includes a plastic substrate, a terminal module, and a fixing film; wherein: the plastic substrate has a vertically penetrating mounting groove, the terminal module is disposed on the mounting groove, the terminal module includes an insulating base and terminals, the terminals include an integrally connected upper contact section, a middle connecting section, and a lower contact section, the insulating base is formed on the middle connecting section, the upper and lower contact sections are symmetrically disposed at the upper and lower ends of the middle connecting section, and both the upper and lower contact sections protrude outside the mounting groove; two fixing films are provided, the two fixing films are respectively disposed at the upper and lower ends of the plastic substrate and contact the insulating base to fix the terminal module, the fixing films are provided with clearance openings corresponding to the mounting groove, and the upper and lower contact sections pass through the corresponding clearance openings and are exposed.
[0008] As a preferred embodiment, the mounting slots are provided in a plurality of spaced arrangement on the plastic substrate, and correspondingly, the terminal modules are provided in a plurality of spaced arrangement on the respective mounting slots, and the clearance openings of the fixing adhesive film are provided in a plurality of spaced arrangement corresponding to the plurality of mounting slots.
[0009] As a preferred embodiment, both the upper contact segment and the lower contact segment include an elastic arm, an inclined arm, and a contact arm arranged sequentially. The elastic arm extends outward in an arc shape from the middle connecting segment and then bends inward. The inclined arm extends outward obliquely from the outer end of the elastic arm, and the contact arm extends in an arc shape inward from the outer end of the inclined arm.
[0010] As a preferred embodiment, the inclined arm is arranged in a gradually decreasing manner towards the contact arm.
[0011] As a preferred embodiment, the side of the intermediate connecting section is provided with a groove, and at least two grooves are provided and arranged at intervals, with the two grooves located on the side of the upper contact section and the lower contact section respectively.
[0012] As a preferred embodiment, four grooves are provided, with two grooves located on opposite sides of the upper end of the intermediate connecting section and the other two grooves located on opposite sides of the lower end of the intermediate connecting section.
[0013] As a preferred embodiment, the fixing film is a black insulating film.
[0014] As a preferred embodiment, the mounting groove has two positioning protrusions extending toward the insulating seat, which are arranged opposite each other on the inner wall of the mounting groove, and the outer wall of the insulating seat is in contact with and positioned by the positioning protrusions.
[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly utilizes the symmetrical one-piece molding of the upper and lower contact sections of the terminal module, eliminating the traditional separate contact structure at both ends of the terminal. This eliminates the need to distinguish the direction and position of the terminal during assembly, reducing the risk of poor welding between the corresponding contact sections and components, ensuring the assembly quality of the product, reducing impedance, and improving the SI performance of the product. At the same time, the setting of two fixing films strengthens the fixing and protection effect of the two ends of the terminal module on the mounting groove, preventing the terminal module from shifting or loosening during molding, thereby improving the stability of the product. The structure is ingenious and reasonable, the assembly is simple, the production efficiency of the product is improved, the user needs are met, and the application range is wide. Furthermore, the design of the elastic arm, inclined arm, and contact arm improves the reliability of contact between the corresponding upper and lower contact sections and other components, thereby enhancing the product's stability in use. At the same time, the positioning protrusion facilitates the contact positioning of the insulating seat in the mounting groove, making it easier for the subsequent fixing of the adhesive film and the insulating seat to connect. The operation is simple, the positioning is accurate, and the assembly is convenient.

[0019] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of an embodiment of the present invention.
[0020] An LGA connector structure includes a plastic substrate 10, a terminal module 11, and a fixing film 12; wherein: The plastic substrate 10 has a through mounting groove 13. The terminal module 11 is disposed on the mounting groove 13. The terminal module 11 includes an insulating base 111 and a terminal 112. The terminal 112 includes an integrally connected upper contact section 113, an intermediate connecting section 114, and a lower contact section 115. The insulating base 111 is formed on the intermediate connecting section 114. The upper contact section 113 and the lower contact section 115 are symmetrically disposed at the upper and lower ends of the intermediate connecting section 114. Both the upper contact section 113 and the lower contact section 115 protrude from the mounting groove 13. Two fixing adhesive films 12 are provided, and the two fixing adhesive films 12 are respectively provided at the upper end and the lower end of the plastic substrate 10 and in contact with the insulating seat 111 for fixing the terminal module 11. The fixing adhesive film 12 is provided with a clearance opening 121 corresponding to the mounting groove 13. The upper contact section 113 and the lower contact section 115 pass through the corresponding clearance opening 121 and are exposed. Preferably, the fixing adhesive film 12 is a black insulating adhesive film. In this embodiment, several mounting slots 13 are provided and spaced apart on the plastic substrate 10. Correspondingly, several terminal modules 11 are provided and respectively disposed on corresponding mounting slots 13. Several clearance openings 121 of the fixing adhesive film 12 are provided and spaced apart corresponding to several mounting slots 13. Thus, through the design of the terminal module, the upper and lower contact sections of the terminal are symmetrically integrally formed, eliminating the traditional separate contact structure at both ends of the terminal. There is no need to distinguish the direction and position of the terminal during assembly, reducing the risk of poor welding between the corresponding contact sections and components, ensuring the assembly quality of the product, low impedance, and improved SI performance of the product. At the same time, the setting of two fixing adhesive films strengthens the fixing and protection effect of the two ends of the terminal module on the mounting slot, preventing the terminal module from shifting or loosening during molding, thereby improving the stability of the product. The structural design is ingenious and reasonable, the assembly is simple, the production efficiency of the product is improved, the user needs are met, and the applicability is wide.
[0021] Furthermore, both the upper contact segment 113 and the lower contact segment 115 include a resilient arm 116, an inclined arm 117, and a contact arm 118 arranged sequentially. The resilient arm 116 extends outward in an arc from the outer end of the intermediate connecting segment 114 and then bends inward. The inclined arm 117 extends outward obliquely from the outer end of the resilient arm 116. The contact arm 118 extends inward in an arc from the outer end of the inclined arm 117. The inclined arm 117 gradually decreases in size from the resilient arm 116 towards the contact arm 118. This improves the reliability of contact between the corresponding upper and lower contact segments and other components, thereby enhancing the stability of the product in use.
[0022] Furthermore, the side of the intermediate connecting section 114 is provided with a groove 119. There are at least two grooves 119 arranged in a parallel manner. The two grooves 119 are located on the sides of the upper contact section 113 and the lower contact section 115, respectively. There are four grooves 119, of which two grooves 119 are located on opposite sides of the upper end of the intermediate connecting section 114, and the other two grooves 119 are located on opposite sides of the lower end of the intermediate connecting section 114.
[0023] Furthermore, the mounting groove 13 has positioning protrusions 131 extending toward the insulating seat. Two positioning protrusions 131 are provided and are arranged opposite each other on the inner wall of the mounting groove 13. The outer wall of the insulating seat 111 contacts and is positioned with the positioning protrusions 131. This facilitates the contact positioning of the insulating seat on the mounting groove, so as to facilitate the contact connection between the adhesive film and the insulating seat in the subsequent fixing process. The operation is simple, the positioning is accurate, and the assembly is convenient.
[0024] The key design feature of this utility model lies in its terminal module design. The upper and lower contact sections of the terminal are symmetrically integrated, eliminating the need for separate contact structures at both ends of the traditional terminal. This eliminates the need to differentiate the direction and position of the terminals during assembly, reducing the risk of poor soldering between the corresponding contact sections and components, ensuring product assembly quality, low impedance, and improved SI performance. Simultaneously, the two fixing films enhance the fixation and protection of the terminal module's ends in the mounting groove, preventing displacement or loosening during molding, thereby improving product stability. The ingenious and reasonable structural design simplifies assembly, improves production efficiency, meets user needs, and has a wide range of applications. Furthermore, the design of the elastic arm, inclined arm, and contact arm improves the reliability of contact between the corresponding upper and lower contact sections and other components, thereby enhancing the product's stability in use. At the same time, the positioning protrusion facilitates the contact positioning of the insulating seat in the mounting groove, making it easier for the subsequent fixing of the adhesive film and the insulating seat to connect. The operation is simple, the positioning is accurate, and the assembly is convenient.
[0025] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
