Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a securely mounted Type-C connector. Background Technology

[0002] USB Type-C, also known as USB-C or Type-C, is a new type of Universal Serial Bus (USB) hardware interface (USB interfaces also include Type-A and Type-B). It emerged alongside the latest USB 3.1 standard. It was released by the USB Developers Forum (USB-IF) in August 2014. Type-C was developed by the USB standardization organization to address the long-standing shortcomings of inconsistent physical interface specifications and unidirectional power transmission in USB interfaces. Its most distinctive feature is that its top and bottom are completely identical, supporting insertion in both directions. Compared to Micro-USB, users no longer need to distinguish between the front and back of the USB port. Furthermore, it integrates charging, display, and data transfer functions.

[0003] Existing Type-C connectors include a Type-C plug and a Type-C female socket, which are interlocked to form an electrical connection. The Type-C female socket typically includes an insulating body, two rows of conductive terminals embedded in the insulating body, and a shielding shell covering the insulating body. The front end of the shielding shell has a mating cavity for interlocking with the Type-C plug. Existing Type-C female sockets use a method of directly soldering the shielding shell to the circuit board. This soldering method is generally completed by soldering. Due to the low melting point of tin, the connection strength between the connector and the circuit board is poor, making it difficult to ensure the secure installation of the connector.

[0004] Therefore, a new technology needs to be developed to solve the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a securely installed Type-C connector that can improve the connection strength between the connector and the circuit board, thus ensuring the secure installation of the connector.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A securely mounted Type-C connector includes an insulating body, a terminal group, and a shielding shell. The terminal group is embedded and fixed to the insulating body, and the shielding shell covers the insulating body. It also includes a fixing plate for connecting to a circuit board. The fixing plate is arranged horizontally above the shielding shell. The fixing plate includes a horizontal plate portion, two vertical plate portions, and two connecting plate portions. The horizontal plate portion extends in a left-right direction and abuts against the upper end of the shielding shell. The two vertical plate portions are respectively connected to the left and right ends of the horizontal plate portion and extend downwards outside the shielding shell. The connecting plate portions are connected to the lower ends of the corresponding vertical plate portions and extend laterally outwards. The connecting plate portions have screw holes for connecting to the circuit board.

[0008] As a preferred embodiment, the vertical plate has a protruding locking block on the side facing the shielding shell, the locking block extends obliquely upward, and the left and right side walls of the shielding shell are recessed with locking grooves, the locking block being snapped into the corresponding locking groove from top to bottom.

[0009] As a preferred embodiment, the vertical plate portion is integrally connected to the horizontal plate portion via a first arc-shaped plate portion, and the connecting plate portion is integrally connected to the vertical plate portion via a second arc-shaped plate portion, wherein the concave directions of the first arc-shaped plate portion and the second arc-shaped plate portion are opposite.

[0010] As a preferred embodiment, the transverse plate is fixed to the upper front side of the shielding shell by laser spot welding, and the transverse plate is provided with a welding point area.

[0011] As a preferred embodiment, the lower left and right sides of the rear end of the shielding shell are provided with solder feet for soldering to the circuit board, and the solder feet extend downward.

[0012] As a preferred embodiment, the insulating body includes a first insulating member, a second insulating member, and a tongue plate member. The first insulating member and the second insulating member are stacked together vertically, and the tongue plate member is embedded and fixed together with the front end of the first insulating member and the front end of the second insulating member.

[0013] The terminal group includes an upper terminal group and a lower terminal group, which are respectively embedded and fixed together with a first insulating member and a second insulating member; the first contact portion of the upper terminal group and the second contact portion of the lower terminal group are exposed on the upper and lower surfaces of the tongue plate member, respectively.

[0014] The first welding part of the upper row terminal group and the second welding part of the lower row terminal group extend beyond the lower end of the first insulating member and the lower end of the second insulating member, respectively. The first welding parts of the upper row terminal group are arranged in a row in the left-right direction, and the second welding parts of the lower row terminal group are arranged in a row in the left-right direction and are located in front of the first welding parts of the upper row terminal group.

[0015] As a preferred embodiment, the front end of the shielding shell is formed with a plug-in cavity, and the tongue plate extends into the plug-in cavity.

[0016] As a preferred embodiment, the upper and lower end faces of the shielding shell are each provided with an inwardly stamped limiting boss at the middle, and the front end of the insulating body is provided with limiting grooves on both the upper and lower sides, and the limiting bosses and limiting grooves are adapted to each other.

[0017] 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 involves setting a fixing plate, which is arranged horizontally above the shielding shell. The fixing plate includes a horizontal plate part, two vertical plate parts, and two connecting plate parts. Screw holes are provided on the connecting plate parts.

[0042] A securely mounted Type-C connector includes an insulating body 10, a terminal group, and a shielding shell 20. The terminal group is embedded and fixed to the insulating body 10, and the shielding shell 20 covers the insulating body 10. The insulating body 10 includes a first insulating member 11, a second insulating member 12, and a tongue member 13. The first insulating member 11 and the second insulating member 12 are stacked together, and the tongue member 13 is embedded and fixed to the front end of the first insulating member 11 and the front end of the second insulating member 12. The front end of the shielding shell 20 forms a mating cavity 21, and the tongue member 13 extends into the mating cavity 21.

[0043] The terminal group includes an upper terminal group 30 and a lower terminal group 40, which are respectively embedded and fixed together with the first insulating member 11 and the second insulating member 12. The first contact portion 31 of the upper terminal group 30 and the second contact portion 41 of the lower terminal group 40 are respectively exposed on the upper and lower surfaces of the tongue plate member 13. The first welding portion 32 of the upper terminal group 30 and the second welding portion 42 of the lower terminal group 40 extend beyond the lower end of the first insulating member 11 and the lower end of the second insulating member 12, respectively. The first welding portion 32 of the upper terminal group 30 is arranged in a row in the left-right direction, and the second welding portion 42 of the lower terminal group 40 is arranged in a row in the left-right direction and is located in front of the first welding portion 32 of the upper terminal group 30.

[0044] The lower end face of the first insulating member 11 and the lower end face of the second insulating member 12 are flush with each other. The lower end face of the first welding part 32 of the upper terminal group 30 and the lower end face of the second welding part 42 of the lower terminal group 40 are flush with each other to facilitate subsequent welding.

[0045] The lower end of the second insulating member 12 is provided with a positioning post 121 protruding downwards. The positioning post 121 extends downwards to the lower end of the shielding shell 20, so that it can be stably positioned with the external structure through the positioning post 121.

[0046] The upper and lower surfaces of the shielding shell 20 are each provided with an inwardly stamped limiting boss 22. The front end of the insulating body 10 is provided with limiting grooves 14 on both the upper and lower sides. The limiting boss 22 and the limiting groove 14 are adapted to each other, so as to limit the depth of the insulating body 10 inserted into the shielding shell 20.

[0047] The lower left and right sides of the rear end of the shielding shell 20 are provided with solder feet 23 for soldering to the circuit board, and the solder feet 23 extend downward.

[0048] The securely mounted Type-C connector also includes a mounting plate 50 for connection to a circuit board.
