Description

Technical Field

[0001] The utility model relates to the technology of connector field, in particular to a connector with shielding function. Background Art

[0002] Connectors are also called connectors. Domestically, they are also called joints and sockets, and generally refer to electrical connectors. These are devices that connect two active components, transmitting current or signals. The male and female ends, when in contact, can transmit information or current, and are also called connectors. The basic performance of connectors can be categorized into three main categories: mechanical, electrical, and environmental. Another important mechanical performance characteristic is the mechanical life of the connector. Mechanical life is actually a durability indicator, referred to as mechanical operation in the national standard GB5095. It is based on a single insertion and removal cycle, and the evaluation criteria are whether the connector can properly perform its connection function (such as contact resistance) after the specified insertion and removal cycles.

[0003] In order to ensure the stability of the plugging process between the female socket and the male plug, the existing connector will choose to add a middle clip in the female socket and the male plug respectively. During the plugging process, the middle clip is engaged to ensure the structural stability of the female socket and the male plug after plugging. The middle clip can only realize a single plugging function. There is also a choice of the middle clip extending backward with a grounding part connected to the external PCB board, which not only makes the overall structure of the connector complicated, but also requires welding the grounding end on the middle clip to the PCB board during installation, making the installation process more troublesome. Therefore, it is necessary to make further improvements to the existing connector structure. Utility Model Content

[0004] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a connector with a shielding function, which can effectively solve the problems of the existing connectors such as the single function of the clips, the complex structure and the cumbersome installation process.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0031] Please refer to Figures 1 to 5 As shown, it shows the specific structure of a preferred embodiment of the present invention, which includes an insulating body 10, a first terminal assembly 20, a second terminal assembly 30, a middle clip 40 and a shielding shell 50.

[0032] The first terminal assembly 20 and the second terminal assembly 30 are both embedded in the insulating body 10. The first terminal assembly 20 and the second terminal assembly 30 are arranged with an interval between the upper and lower parts. The first terminal assembly 20 has a first signal terminal 21 and a first ground terminal 22, and the second terminal assembly 30 has a second signal terminal 31 and a second ground terminal 32. The first signal terminal 21, the first ground terminal 22, the second signal terminal 31 and the second ground terminal 32 are respectively exposed on the upper and lower surfaces of the insulating body 10.

[0033] In this embodiment, the first terminal assembly 20 includes a first mounting plate 23, in which the first signal terminal 21 and the first ground terminal 22 are embedded. The second terminal assembly 30 includes a second mounting plate 33, in which the second signal terminal 31 and the second ground terminal 32 are embedded. The first mounting plate 23 is provided with two positioning holes 201 arranged laterally and spaced apart, and the second mounting plate 33 is provided with two positioning posts 331 that cooperate with the positioning holes 201. The insulating body 10 includes a main body 11 and a tongue plate 12 extending forward from the main body 11.

[0034] The middle clip 40 is embedded in the insulating body 10 and sandwiched between the first terminal assembly 20 and the second terminal assembly 30. The left and right sides of the middle clip 40 integrally extend outward with a snap-fit ​​portion 41 that extends outward from the insulating body 10 and a first contact portion 42. The middle clip 40 is in contact and conductive with the first grounding terminal 22 and the second grounding terminal 32, respectively. The snap-fit ​​portion 41 achieves a snap-fitting effect when plugging into an external connector, thereby ensuring a stable plugging process. The contact with the first and second grounding terminals 22 and 32 also shields the first and second terminal assemblies 20 and 30, preventing signal crosstalk within them during operation. In this embodiment, the middle clip 40 is sandwiched between the first mounting plate 23 and the second mounting plate 33. The middle clip 40 is provided with a through hole 401 that cooperates with the positioning column 331. During installation, the middle clip 40 can be placed on the second mounting plate 33 first, and then the first mounting plate 23 and the second mounting plate 33 are positioned and installed together through the positioning column 331 and the positioning hole 201, and then placed together in a mold and injection molded to form the insulating body 10.

[0035] The middle clip 40 is integrally bent upward and downward to form two elastically arranged second contact portions 43, and the two second contact portions 43 are elastically contacted with the corresponding first grounding terminal 22 and second grounding terminal 32 respectively. The elastically arranged second contact portion 43 can ensure the stability of the contact between the second contact portion 43 and the first grounding terminal 22 and the second grounding terminal 32. The snap-fit ​​portion 41 extends outward from the left and right sides of the tongue plate 12, and the first contact portion 42 extends outward from the left and right sides of the main body 11.

[0036] The shielding shell 50 is mounted over the outer periphery of the insulating body 10. The shielding shell 50 not only protects the insulating body 10 but also prevents interference from external signals on the first and second terminal assemblies 20 and 30. The first contact portion 42 is in contact with and electrically connected to the shielding shell 50, further enhancing the shielding function of the middle clip 40. In this embodiment, a mounting bracket 51 is provided on the outside of the shielding shell 50. The mounting bracket 51 is welded to the shielding shell 50, and the connector body is fixedly mounted to the outside via the mounting bracket 51.

[0037] The assembly process of this embodiment is described in detail as follows:

[0038] First, place the first signal terminal 21 and the first ground terminal 22 in the mold to form the first mounting plate 23, and place the second signal terminal 31 and the second ground terminal 32 in the mold to form the second mounting plate 33. Then, place the stamped middle clip 40 on the second mounting plate 33, and install the first mounting plate 23 on the second mounting plate 33, so that the middle clip 40 is clamped between the first mounting plate 23 and the second mounting plate 33. Then, place the assembled first mounting plate 23 and the second mounting plate 33 together into the corresponding mold to form the insulating body 10, and then install the shielding shell 50 on the outside of the insulating body 10. Finally, weld the mounting frame 51 to the shielding shell 50.

[0039] The design focus of the present utility model is that: a buckling portion and a first contact portion extending outward from the left and right sides of the middle clip are integrally extended outward with the insulating body, and the buckling portion cooperates with the middle clip of the external plug connector to achieve a stable connection function, and cooperates with the middle clip to contact and conduct with the first grounding terminal and the second grounding terminal respectively, and the first contact portion is in contact and conduction with the shielding shell, so that it is simultaneously in contact and connected with the first grounding terminal, the second grounding terminal and the shielding shell to achieve the function of shielding internal signals, preventing the problem of signal crosstalk between the first terminal assembly and the second terminal assembly, and having stronger functionality; and the middle clip does not require an additional grounding terminal to be welded to the external PCB board, making the overall structure and installation process simpler and more convenient.

[0040] The above description is merely a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any minor modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
