Description

Technical Field

[0001] The utility model relates to the technology of the field of electrical connectors, and in particular to a raised-type patch-type Type-C connector. Background Art

[0002] Type-C is a USB interface standard that is smaller than Type-A and Type-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones). USB Type-C has four pairs of TX / RX breakout lines, two pairs of USB D+ / D-, one SBU pair, two CC lines, four VBUS lines, and four ground lines.

[0003] The current Type-C connector mainly consists of an insulating body, a terminal group, and a shielding shell. The insulating body includes a base and a tongue extending forward from the base. The terminal group is arranged on the insulating body and has multiple contact portions and multiple soldering portions. The multiple contact portions are exposed on the upper and lower surfaces of the tongue. The shielding shell covers the insulating body.

[0004] In existing technology, when a Type-C connector is mounted on an external circuit board, the entire bottom surface of its shielding shell aligns with the surface of the external circuit board, occupying a large area on the circuit board. This reduces the area available for mounting electronic components, necessitating an increase in the circuit board area, and hindering the development of device miniaturization. Therefore, it is necessary to develop a solution to this problem. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies in the prior art, and its main purpose is to provide a raised, surface-mount Type-C connector that can effectively solve the problem that the existing Type-C connector occupies a large area on the circuit board, resulting in a smaller area for mounting electronic devices.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A raised, patch-type Type-C connector comprises an insulating body, a terminal group, and a shielding shell; the insulating body comprises a base and a tongue extending forward from the base; the terminal group is disposed on the insulating body, the terminal group having multiple contact portions and multiple soldering portions, the multiple contact portions being exposed on the upper and lower surfaces of the tongue plate, respectively; the shielding shell is wrapped around the insulating body; the bottom rear side of the shielding shell has a notch, the base extends downwardly from a raised portion, the raised portion is located in the notch and extends downward through the notch, an escape space for accommodating electronic devices is formed between the front side of the raised portion and the bottom surface of the shielding shell, and the multiple soldering portions extend outside the raised portion.

[0008] As a preferred solution, a fixing column is integrally extended downward from the bottom surface of the raised portion so as to be installed and fixed with an external circuit board.

[0009] As a preferred solution, the fixing column is a cylinder, and there are two fixing columns arranged symmetrically on the left and right, which makes the installation with the external circuit board more stable.

[0010] As a preferred solution, the plurality of soldering portions are arranged in parallel to form a row, which is exposed from the bottom surface of the raised portion and extends horizontally backward to the rear side of the raised portion, so as to be soldered and fixed on an external circuit board in a patch manner.

[0011] As a preferred solution, the front bottom edge and top edge of the base are both recessed with limiting grooves, and the rear top edge of the base is recessed with a snap-fitting groove. Correspondingly, a limiting portion is punched and bent from the outside to the inside on the shielding shell, and the limiting portion is snapped into the limiting groove from front to back, and a snap-fitting piece is punched and bent and extends from the top of the rear side of the shielding shell. The snap-fitting piece is fixed with the snap-fitting groove to make the assembly of the shielding shell and the insulating body simple and stable.

[0012] As a preferred solution, bayonet holes are provided on both sides of the rear end of the shielding shell, and latch protrusions are extended outward on both sides of the rear end of the base, which are engaged in the bayonet holes to prevent the shielding shell from moving backward.

[0013] As a preferred solution, a plurality of fixing legs are punched out and extended from the shielding shell, and the plurality of fixing legs extend vertically downward so as to be mounted and fixed to the external circuit board.

[0015] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0016] By extending a raised portion downward from the base and forming an escape space for accommodating electronic components between the front side of the raised portion and the bottom surface of the shielding shell, the product is effectively prevented from occupying a large area on the circuit board, thereby increasing the area on the circuit board where electronic components can be installed. Under the premise of installing the same number of electronic components, there is no need to increase the area of the circuit board, which is more conducive to the development of miniaturization of equipment.

[0034] Please refer to Figures 1 to 5 , which shows the specific structure of a preferred embodiment of the present invention, including an insulating body 10 , a terminal group 20 and a shielding shell 30 .

[0035] The insulating body 10 includes a base 11 and a tongue plate 12 integrally extending forward from the base 11, and a raised portion 13 integrally extending downward from the base 11. In this embodiment, the front bottom and top edges of the base 11 are both recessed with a limiting groove 101, and the rear top edge of the base 11 is recessed with a snap-fit groove 102. Both the limiting groove 101 and the snap-fit groove 102 are symmetrically arranged on the left and right. Both sides of the rear end of the base 11 have latching protrusions 103 extending outward. In addition, a fixing column 104 integrally extends downward from the bottom surface of the raised portion 13 so as to be mounted and fixed to an external circuit board. Moreover, the fixing column 104 is a cylinder, and the two fixing columns 104 are symmetrically arranged on the left and right, which makes the installation with the external circuit board more stable. The raised portion 13 is a block.

[0036] The terminal assembly 20 is mounted on the insulating body 10 and includes a plurality of contact portions 21 and a plurality of soldering portions 22. The contact portions 21 are exposed on the upper and lower surfaces of the tongue plate 12. In this embodiment, the soldering portions 22 are arranged in a row, exposed from the bottom surface of the raised portion 13, and extend horizontally rearwardly beyond the rear side of the raised portion 13, allowing for surface mount soldering and attachment to an external circuit board. The terminal assembly 20 is comprised of 16 pin terminals, but this is not a limitation.

[0037] The shielding shell 30 is wrapped around the insulating body 10. The bottom rear side of the shielding shell 30 has a notch 31. The raised portion 13 is located in the notch 31 and extends downward through the notch 31. A clearance space 301 for accommodating electronic devices is formed between the front side of the raised portion 13 and the bottom surface of the shielding shell 30. The height of the clearance space 301 is 1.0 mm. The multiple welding portions 22 extend outside the raised portion 13. In this embodiment, the shielding shell 30 is an iron shell formed by stamping. A limiting portion 32 is punched and bent from the outside to the inside of the shielding shell 30. The limiting portion 32 is inserted into the limiting groove 101 from the front to the back to prevent the shielding shell 30 from moving backward. A snap-fitting piece 33 is punched and bent and extends from the top of the rear side of the shielding shell 30. The snap-fitting piece 33 is fixed with the snap-fitting groove 102 to prevent the shielding shell 30 from moving forward. In addition, the rear end of the shielding shell 30 is provided with a bayonet 34 on both sides. The latch 103 is locked in the bayonet 34 to prevent the shielding shell 30 from moving backward. In addition, the shielding shell 30 is punched out with a plurality of fixing feet 35 extending vertically downward to facilitate mounting and fixing with an external circuit board. The plurality of fixing feet 35 are respectively located on the left and right sides of the shielding shell 30 and are arranged in a spaced-apart manner front to back. The fixing feet 35 located on the front side are formed with a step structure 351. The step structure 351 is located on the rear side of the fixing foot 35. The height of the step structure 351 is flush with or slightly higher than the soldering portion 22, thereby supporting the entire product and preventing the product from tipping over and causing poor soldering.

[0038] The assembly process of this embodiment is described in detail as follows:

[0039] First, the terminal group 20 is stamped out, and then the terminal group 20 is placed in an injection mold to injection mold the insulating body 10, so that the terminal group 20 and the insulating body 10 are inlaid and fixed together to form a semi-finished product. Then, the semi-finished product is inserted from the rear end opening of the shielding shell 30. After being inserted into place, the limiting portion 32 is clamped in the limiting groove 101, and the clamping protrusion 103 is clamped in the clamping port 34. Finally, the snap-fitting piece 33 is bent downward to cooperate with the snap-fitting groove 102 for snap-fit fixation.

[0040] When in use, the fixing column 104 and the fixing foot 35 are respectively inserted into the corresponding fixing holes of the external circuit board and fixed. At the same time, the multiple welding parts 22 are welded on the corresponding welding pads of the external circuit board. At this time, some electronic components on the external circuit board are located in the avoidance space 301.

[0041] The design focus of the present invention is that a raised portion is integrally extended downward from the base, and an escape space for accommodating electronic components is formed between the front side of the raised portion and the bottom surface of the shielding shell, thereby effectively avoiding the product occupying a large area on the circuit board, thereby increasing the area on the circuit board where electronic components can be installed. Under the premise of installing the same number of electronic components, there is no need to increase the area of the circuit board, which is more conducive to the development of miniaturization of equipment.

[0042] 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.
