Description

Adapter Card Retainer Structure

technical field

The utility model relates to an adapter card fixing device structure, which is used in the field of electrical appliances, computers and electronic products.

Background technique

Nowadays, with the advancement of science and technology, electronic products are extremely diversified to meet the needs of all levels of the market. The product's small size, small space and easy portability are common demands of the market. Therefore, the industry spares no effort in research and development. The purpose of product performance and miniaturization is continuously improved.

Among them, in order to meet the goals of high performance, compact size and easy assembly, computer and electronic products have undergone obvious reform and changes in the specifications and structural shapes of each component of the products, mainly to achieve the purpose of reducing the volume.

In response to factors such as hardware function requirements and limited space of computer products, it is necessary to make full use of the effective space of the computer body, so a new specification has been formed (refer to Figure 1) for multi-layer adapter cards (interface cards) to be inserted and used, which is based on The connectors 20 of different heights are arranged in a gradually increasing manner, so the sockets of the connectors 20 will not be obstructed, and the adapter cards 30, 30a can be plugged together for use.

However, the fixing device 10 currently on the market is only suitable for snap-fit positioning of the single-layer or first-layer adapter card 30 , while the other upper layer (second layer) adapter card 30a is not suitable.

In order to meet the above-mentioned needs, the inventor has continued to research and experiment, and has improved and formed a fixed device structure design that is flexible and can meet the height of the adapter card. On October 12, 2006, he filed a Chinese patent application "A Adapter Grounding structure of card fixing device" (application number 200620133445.8).

In order to meet the needs of various components in the market and to reduce the cost, the inventor conducted further research and experiments, and finally developed a structural design of a fixing device that is formed by direct bending of a metal sheet and can meet the height of the mating card.

Utility model content

The purpose of the utility model is to provide an adapter card fixing device structure, which is suitable for the use of adapter buckle fixing positions with different specifications and heights.

The purpose of this utility model is achieved in this way, an adapter card fixing device structure, the fixing device is formed by stamping and bending a metal sheet, the fixing device is a seat plate with pins on both sides bent upwards and extended The arc angle and a spring body, the spring body extends forward and is folded with a buckle top body with an inclined guiding surface. The body is reversely folded; moreover, a convex top is protruded on the back side of the spring body.

From the above, the structure of the adapter card fixing device of the present invention can indeed be used for the adapter card fixing positions adapting to different specifications and heights.

Detailed ways

Fig. 2a to Fig. 2c are three-dimensional schematic diagrams of various angles of view of the fixing device of the present utility model, as shown in the figure, the fixing device 400 formed by punching and bending a metal sheet (also refer to Fig. 3a, Fig. 3b, Fig. 4a, Fig. 4b), a seat plate 40 with pins 40a on both sides is bent upwards and has an arc angle 401b and a spring body 401. The spring body 401 extends forward and is folded with a buckle top body 402 with an inclined guiding surface. In addition, the two sides of the spring body 401 are respectively folded with a puller body 403 and a corner top body 404, wherein the puller body 403 and the buckle top body 402 are folded in opposite directions; and the back side of the spring body 401 is convexly provided with a convex top 401a.

Fig. 5 is a top view schematic diagram of the implementation of the fixing device of the present invention. As shown in the figure, (see Fig. 6a, Fig. 6b, Fig. 7) an A connector 20, a B connector 20a and a The (known) fixing structure 500 corresponding to the A connector 20 is especially provided with a socket at a suitable position of the machine board 200 for fixing the fixing device 400. Firstly, an A adapter card 300 is inserted and combined with the A connector 20 Press down to secure the fixing structure 500, then insert the B adapter card 350 into the B connector 20a and press down on the end, (see also Figure 8a to Figure 8b) the two sides of the end of the B adapter card 350 are against the The inclined guide surfaces of the buckle top bodies 402 of the two fixing devices 400 are pressed down, and the two buckle top bodies 402 are pushed outward by the elasticity of the spring body 401 and the arc angle 401b to form an axial outward expansion displacement, forming a space for B to fit When the card 350 enters the horizontal position, the two buckle top bodies 402 bounce back to the position due to the elasticity of the spring body 401 and the arc angle 401b. The corner body 404 on one side can be used for the bottom side of the B adapter card 350 to lean against and the top to block at the right angle to the end of the B adapter card 350 to prevent displacement.

It can be seen from this that the fixing device 400 of the present invention can indeed achieve the purpose and effect of fixing the B adapter card 350 on the upper layer.

Although the utility model has been disclosed with specific embodiments, it is not intended to limit the utility model. Any person skilled in the art can replace equivalent components without departing from the concept and scope of the utility model, or The equivalent changes and modifications made according to the scope of protection of the utility model patent should still fall within the scope of this patent.
