Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a modularly designed vertical connector. Background Technology

[0002] Connectors, also known as plugs or sockets, are generally electrical connectors. They are devices that connect two active devices to transmit current or signals. The male and female terminals, upon contact, can transmit information or current, hence the name connector. A connector typically consists of an insulating body and terminals mounted on the insulating body. When a connector is plugged into an external device, the transmission of signals and current primarily occurs between these terminals. Currently, connector manufacturing involves placing the terminal assembly in a mold and then directly injection molding the insulating body, thus achieving the installation process between the insulating body and the terminals. Therefore, the current method of molding the terminals and insulating body is cumbersome, and defective products require the entire product to be scrapped, resulting in wasted costs. Therefore, it is necessary to further improve the existing connector structure. Utility Model Content

[0003] In view of this, the present invention addresses the deficiencies of the existing technology, and its main purpose is to provide a modularly designed vertical connector that can effectively solve the problems of cumbersome assembly process and cost waste in existing connectors.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A modular vertical connector includes an insulating body, terminal assemblies, and a shielding shell. The insulating body has an integrally recessed insertion cavity at its front end for external engagement, and a mounting cavity communicating with the insertion cavity at its rear end. Two mounting cavities are arranged vertically, and a positioning post extends rearward from the rear end of the insulating body for external engagement. Two terminal assemblies are provided, each inserted into a corresponding mounting cavity. Each terminal assembly includes a mounting base and a terminal group. The mounting base mates with the corresponding mounting cavity, and the terminal group is embedded in the mounting base. The terminal group includes multiple terminals arranged laterally at intervals. The front end of each terminal extends forward from the mounting base and into the insertion cavity to form a contact portion, and the rear end of each terminal extends rearward from the mounting base and the rear end of the insulating body to form a solder portion. The shielding shell covers the outer periphery of the insulating body.

[0006] As a preferred embodiment, the insertion cavity is provided with a mounting groove extending forward and backward. The mounting grooves are multiple grooves arranged laterally at intervals, and the contact portion of each terminal is located in the corresponding mounting groove.

[0007] As a preferred option, the front end of the mounting groove is provided with a limiting part, the contact part is integrally bent and formed, and the front end of the contact part abuts against the inner sidewall of the limiting part.

[0008] As a preferred option, the positioning posts are arranged in two horizontally spaced columns, with one column being larger than the other.

[0009] As a preferred embodiment, the front end of the inner sidewall of the mounting cavity is provided with a laterally extending protrusion, and the upper and lower inner sidewalls of the mounting cavity are provided with anti-retraction grooves extending forward and backward; the upper and lower surfaces of the mounting base are provided with anti-retraction parts that cooperate with the rear sidewall of the anti-retraction grooves, and the front end of the mounting base abuts against the rear sidewall of the protrusion.

[0010] As a preferred option, the upper and lower sides of the front end of the shielding shell are integrally bent inward to form elastic parts, which extend inward into the insertion cavity. The elastic parts are multiple parts arranged laterally at intervals.

[0011] As a preferred embodiment, the left and right side walls of the insulating body are provided with first fastening portions protruding outwards, and the shielding shell is provided with first fastening holes that cooperate with the first fastening portions. The shielding shell is fastened to the insulating body by the cooperation of the first fastening portions and the first fastening holes.

[0012] As a preferred option, the rear left and right sides of the shielding shell are integrally extended rearward with connecting feet for external engagement, and each side has two connecting feet arranged vertically at intervals.

[0013] As a preferred option, the connection between the shielding shell and the connecting foot is integrally provided with a reinforcing rib that protrudes outward.

[0014] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0015] The insulating body has a mounting cavity with a connecting insertion cavity at its rear end. Each terminal assembly includes a mounting base and a terminal group. The mounting base is installed together with the corresponding mounting cavity, and the terminal group is embedded in the mounting base. This allows the insulating body and mounting base to be injection molded sequentially, and then assembled together. Compared with the existing integral injection molding method, the overall product assembly process is more convenient. Moreover, even if defective products are found, only the insulating body or mounting base needs to be scrapped separately, without scrapping the entire product, thus avoiding cost waste.

[0033] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which includes an insulating body 10, a terminal assembly 20, and a shielding shell 30.

[0034] The insulating body 10 has an integrally recessed insertion cavity 101 at its front end for mating with the external circuit board. The rear end of the insulating body 10 has an installation cavity 102 communicating with the insertion cavity 101. Two installation cavities 102 are arranged vertically. The rear end of the insulating body 10 also integrally extends rearward with a positioning post 11 for mating with the external circuit board. The positioning post facilitates the positioning and installation process with the external circuit board. In this embodiment, the insertion cavity 101 has a front-to-back extending installation groove 103, which is arranged horizontally at intervals. A limiting part 12 is provided at the front end of each installation groove 103. Two positioning posts 11 are arranged horizontally at intervals, with one large and one small post to prevent reverse insertion when the insulating body 10 is connected to the external circuit board. The front end of the inner wall of the installation cavity 102 has a horizontally extending protrusion 13, and the upper and lower inner walls of the installation cavity 102 have front-to-back extending anti-retraction grooves 104. The left and right side walls of the insulating body 10 are provided with first buckle portions 14 protruding outward.

[0035] The terminal assembly 20 is provided in two configurations. Each terminal assembly 20 is inserted into a corresponding mounting cavity 102. Each terminal assembly 20 includes a mounting base 21 and a terminal group 22. The mounting base 21 is fitted together with the corresponding mounting cavity 102. The terminal group 22 is embedded in the mounting base 21 and includes multiple terminals 221 arranged laterally at intervals. The front end of each terminal 221 extends forward from the mounting base 21 and into the insertion cavity 101 to form a contact portion 222, which is used for contact and conduction with the terminals of an external connector. The rear end of each terminal 221 extends backward from the mounting base 21 and the rear end of the insulating body 10 to form a welding portion 223, which is used for welding and conduction with an external circuit board. The contact portion 222 is integrally bent and formed, and the front end of the contact portion 222 abuts against the inner sidewall of the limiting portion 12. The limiting portion 12 limits the position of the front end of the contact portion 222, ensuring the stability of the overall structure.

[0036] In this embodiment, the contact portion 222 of each terminal 221 is located in the corresponding mounting groove 103, so that it is positioned by the mounting groove 103 and the contact portion 222, preventing it from being misaligned to the left or right and causing poor contact with the external connector terminal. The upper and lower surfaces of the mounting base 21 are provided with anti-retraction portions 211 that cooperate with the rear sidewall of the anti-retraction groove 104. The front end of the mounting base 21 abuts against the rear sidewall of the protrusion 13. Through the cooperation between the anti-retraction groove 104 and the rear end face of the anti-retraction portion 211 and the cooperation between the protrusion 13 and the front end face of the mounting base 21, the mounting base 21 is limited in the front-back direction, preventing the mounting base 21 from falling out of the mounting cavity 102.

[0037] The shielding shell 30 covers the outer periphery of the insulating body 10 and serves as a shield to prevent interference from external signals during connector operation. In this embodiment, the upper and lower sides of the front end of the shielding shell 30 are integrally bent inward to form elastic portions 33. These elastic portions 33 extend inward into the insertion cavity 101. Multiple elastic portions 33 are arranged laterally at intervals, allowing for elastic contact with the sidewall of the external connector inserted into the insertion cavity 101, thereby clamping the external connector and making the connection process more stable. The shielding shell 30 has a first fastening hole 301 that mates with the first fastening part 14. The shielding shell 30 is fastened to the insulating body 10 through the engagement of the first fastening part 14 and the first fastening hole 301. The shielding shell 30 has integrally extended connecting feet 31 on both the left and right rear sides for external cooperation. There are two connecting feet 31 on each side, arranged vertically at intervals. The shielding function is achieved through the connection between the connecting feet 31 and the external circuit board. The connection between the shielding shell 30 and the connecting feet 31 is integrally provided with reinforcing ribs 32 that protrude outwards. The reinforcing ribs 32 increase the structural strength of the connecting feet 31 and prevent them from deforming.

[0038] The key design feature of this invention is that the rear end of the insulating body has a mounting cavity that connects to the insertion cavity, and each terminal assembly includes a mounting base and a terminal group. The mounting base is installed together with the corresponding mounting cavity, and the terminal group is embedded in the mounting base. This allows the insulating body and the mounting base to be injection molded sequentially, and then assembled together. Compared with the existing integral injection molding method, the overall product assembly process is more convenient. Moreover, even if defective products are found, only the insulating body or the mounting base needs to be scrapped separately, without scrapping the entire product, thus avoiding cost waste.

[0039] 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.
