Description

Electrical Connector Assembly

【Technical field】

The utility model relates to an electrical connector assembly, in particular to an electrical connector assembly which can be electrically connected to a printed circuit board.

【Background technique】

Due to the high-speed data transmission of the computer and the operation requirements, the working hours of the computer are getting longer and longer. Correspondingly, the heat generated by the central processing unit is increasing. It is necessary to use a cooling device to dissipate the heat generated by the computer when it is working heat. When the heat sink is installed on the printed circuit board, since the printed circuit board cannot bear the weight of the heat sink, a back plate is generally added to strengthen the strength of the printed circuit board. At present, there are generally two types of backplanes commonly used in the industry, one is the backplane formed by plastic, and the other is the backplane formed by metal stamping. The backplane formed by plastic is easy to manufacture and the cost is low, but in Its strength is limited during use, and sometimes it cannot achieve the desired strength. As shown in FIG. 1, a conventional electrical connector assembly 100' includes an electrical connector 1' and a metal back plate 4' for electrically connecting a chip module 5' to a printed circuit board 3'. The metal backplane 4' has high strength, which can meet the requirement of strength, but it is necessary to ensure the insulation effect between the metal backplane 4' and the printed circuit board 3'. At present, a kind of existing technology is by sticking a kind of soft insulation sheet (not shown) on the upper surface of the backboard 4'.

However, this kind of insulating sheet has no positioning features and is glued together, so it is easy to stick crookedly, produce wrinkles and air bubbles, and thus it is difficult to assemble.

Therefore, it is necessary to design a new electrical connector assembly to overcome the above disadvantages.

【Content of utility model】

The purpose of the utility model is to provide an electrical connector assembly, which can achieve a good insulation effect between the metal backboard and the printed circuit board and is easy to assemble.

In order to achieve the above purpose, the utility model adopts the following technical solution: an electrical connector assembly, including an electrical connector and a metal backboard, wherein the electrical connector is fixed to the top of the printed circuit board for electrically connecting the chip module and the printed circuit board. The circuit board and the metal backboard are assembled to the bottom of the printed circuit board, and an insulating plastic sheet is arranged between the printed circuit board and the printed circuit board, and is provided with a hook to fasten to the metal backboard.

Compared with the prior art, the insulating plastic sheet in the electrical connector assembly of the utility model can achieve a good insulating effect, and can be fastened to the metal backboard through hooks, which is easy to assemble and does not cause inaccurate positioning.

【Detailed ways】

As shown in FIGS. 2 , 3 and 4 , the electrical connector assembly 100 of the present invention includes an electrical connector 1 , a metal back plate 5 and an insulating plastic sheet 4 .

The electrical connector 1 is installed above the printed circuit board 3 for electrically connecting the chip module 6 to the printed circuit board 3 . It is provided with a plurality of mounting holes 11 , and the printed circuit board 3 is correspondingly provided with a plurality of circular holes 31 .

The metal back plate 5 is a plate-shaped structure formed by punching, and is installed under the printed circuit board 3 to strengthen the strength of the printed circuit board 3 . It is provided with an assembly hole 51 corresponding to the circular hole 31 on the printed circuit board 3 .

The insulating plastic sheet 4 is arranged between the metal backplane 5 and the printed circuit board 4. It has a flat structure and is slightly larger than the metal backplane 5. The four sides of the insulating plastic sheet 4 extend out from the hooks 42. In this embodiment, the insulating plastic sheet A hook 42 is extended from each of the four sides of the sheet 4 to fasten to the four sides of the metal backplane 5. Please also refer to FIG. . The insulating plastic sheet 4 is provided with positioning holes 41 corresponding to the circular holes on the printed circuit board 3 .

The utility model passes through the mounting hole 11 on the electrical connector 1, the round hole 31 on the printed circuit board 3, the positioning hole 41 on the insulating plastic sheet 4 and the hole on the metal back plate 5 through the fixing device, such as the screw 2. The assembly holes 51 are used to securely assemble the electrical connector 1 , the insulating plastic sheet 4 and the metal back plate 5 to the printed circuit board 3 .

The key structure of the utility model is: an insulating plastic sheet 4 is set between the metal backboard 5 and the printed circuit board 3, and it is provided with a hook 42 to fasten to the metal backboard 5, so that the metal backboard 5 and the printed circuit board 3 Good insulation effect and easy assembly are achieved.

It should be pointed out that the above description is only one embodiment of the utility model, not all or the only implementation manner, any equivalent changes adopted by those of ordinary skill in the art to the technical solution of the utility model by reading the description of the utility model, All are covered by the claims of the present utility model.
