Detailed Implementation Methods

[0029] Example 1:

[0030] Please refer to Figures 1-7 This embodiment is a side-by-side connector assembly 100, which includes a first plastic shell 1 and a plurality of connectors 2 arranged side-by-side inside the first plastic shell 1. The first plastic shell 1 is provided with a plurality of mounting slots 11 for accommodating the connectors 2. The mounting slots 11 are through and have a hollow opening 12 at the bottom. The connectors 2 are installed in the corresponding mounting slots 11, and the front side forms a plug interface 21 and the bottom is provided with a plurality of terminal solder feet 22. The terminal solder feet 22 are exposed and extend out of the hollow opening 12 to be soldered to the PCB motherboard. The connectors 2 have vertical floating space in the mounting slots 11 and the top is provided with an upwardly protruding spring piece 23. The top of the spring piece 23 is pressed down by the top wall of the mounting slot 11, so that the terminal solder feet 22 at the bottom of the connector 2 are tightly attached to the solder pads on the PCB motherboard, effectively solving problems such as cold solder joints, missing solder joints, and empty solder joints.

[0031] A flat inner shielding cover 13 is installed on the top of the first plastic housing 1. A first outer iron shell 3 is provided around the outer periphery of the first plastic housing 1. The first outer iron shell 3 covers the left and right side surfaces, the top surface, and the rear surface of the first plastic housing 1, and is welded to the inner shielding cover 13 to strengthen the connection between the first plastic housing 1 and the first outer iron shell 3. The first outer iron shell 3 enhances the shielding against external interference signals and increases the protection of the first plastic housing 1, thereby improving the overall structural strength of the parallel connector assembly.

[0032] A pair of first sliding grooves 111 and a pair of second sliding grooves 112 are provided on the inner walls of the left and right sides of the mounting groove 11. The first sliding grooves 111 are located near the upper side of the mounting groove 11, and the second sliding grooves 112 are located near the lower side of the mounting groove 11. A first support block 24 extending into the first sliding groove 111 and a second support block 25 extending into the second sliding groove 112 are provided on the left and right sides of the connector 2. The first sliding grooves 111 and the second sliding grooves 112 extend rearward to the rear side of the first plastic housing 1.

[0033] The connector 2 is of HDMI, US or other types. When it is installed in the mounting slot 11, it slides forward from the rear side of the first plastic shell 1 along the first slide groove 111 and the second slide groove 112. The second slide groove 112 extends forward from the rear side of the first plastic shell 1 by a set length, limiting the depth of the connector 2 to be inserted forward, thereby achieving front-side limiting. The left and right ends of the first support block 24 are limited by the inner walls of the left and right sides of the first slide groove 111, and the left and right ends of the second support block 25 are limited by the inner walls of the left and right sides of the second slide groove 112, thereby limiting the position of the connector 2 on the left and right sides. Meanwhile, the first support block 24 in the first slide groove 111 and the second support block 25 in the second slide groove 112 both have upward floating space. This allows the connector 2 to be slightly raised relative to the first plastic shell 1 within the mounting groove 11 when soldering with the PCB motherboard. Simultaneously, the spring piece 23 presses the connector 2 downwards, elastically pressing it against the PCB motherboard. This ensures that all the terminal solder feet 22 at the bottom of the connector 2 are tightly attached to the PCB motherboard, preventing defects such as cold solder joints, missing solder joints, or empty solder joints. The rear position of the connector 2 within the mounting groove 11 is limited by the first outer iron shell 3 covering and blocking the rear surface of the first plastic shell 1. At this time, the left-right and front-back positions of the connector 2 within the first plastic shell 1 are restricted, thereby ensuring that the bottom terminal solder feet 22 can accurately align with the solder pads on the PCB motherboard, preventing soldering deviations.

[0034] Connector 2 includes a second plastic housing 26, a plastic terminal assembly 27 installed inside the second plastic housing 26, and a second outer metal shell 28 covering the outer periphery of the second plastic housing 26. The left and right sides of the second plastic housing 26 have several protruding structures that form the aforementioned first support block 24 and second support block 25. The second outer metal shell 28 covers the left and right sides, front and rear sides, top surface, and bottom portion of the second plastic housing 26. The bottom of the second outer metal shell 28 extends downwards with several positioning teeth 281 distributed around the terminal solder pad area 22. The second outer metal shell 28 is formed by the first metal shell 282 and the second metal shell 283. The top of the second outer metal shell 28 has a piercing protrusion that forms the aforementioned spring piece 23, which abuts against the inner top wall of the mounting groove 11. The positioning teeth 281 effectively fix the position of the connector 2, thereby improving the positional stability of the side-by-side connector assembly on the PCB motherboard.

[0035] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
