Detailed Description

in order to make the above objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, as those skilled in the art will be able to make similar modifications without departing from the spirit and scope of the present invention.

As shown in fig. 1-2, the utility model provides a steel sheet device for cell-phone presses BTB which characterized in that, a steel sheet device for cell-phone presses BTB includes:

the steel sheet body 2 is used for pressing the BTB on the mobile phone mainboard 1;

the screw area 3 is arranged at one end of the steel sheet body 2;

The SMT area 4 is arranged at the other end of the steel sheet body 2; and

And through holes matched with the screw area 3 and the SMT area 4 are respectively arranged on the mainboard 1.

Specifically, the BTB, i.e., the board-to-board connector, is a connector product with the strongest transmission capability among all connector product types at present, and is mainly applied to industries such as power systems, communication networks, financial manufacturing, elevators, industrial automation, medical equipment, office equipment, home appliances, military manufacturing, and the like.

SMT is Surface Mount Technology (Surface Mount Technology), an acronym for Surface Mount Technology, which is currently the most popular technique and process in the electronic assembly industry. SMT components generally include surface mount technology, surface mount equipment, surface mount components, SMT management. The surface-mounted component (SMC/SMD, chip component in Chinese) with no pins or short leads is mounted on the surface of a Printed Circuit Board (PCB) or other substrates, and is soldered and assembled by methods such as reflow soldering or dip soldering.

The steel sheet body 2 can determine the specific shape according to the shape of the BTB on the main board 1, and the steel sheet body 2 presses on the BTB, and mainly plays a role in protecting the main board 1 and the BTB. The one end of the steel sheet body 2 can be provided with a screw area 3 through an integral forming process, the screw area 3 is usually close to the side edge of the main board 1, and the side edge of the main board 1 is usually inconvenient to use, so that the two traditional screw areas 3 are not removed, the screw area 3 close to the side edge of the main board 1 is reserved, and the fixing property between the steel sheet body 2 and the main board 1 is ensured under the condition that the other end adopts the SMT assembling process. The SMT area 4 adopts the SMT production process, so that the small steel sheet does not need to be punched, parts can be arranged at the punching position of the main board 1 and just on the back of the small steel sheet, and the area of the main board 1 is saved.

in some embodiments, the steel sheet body 2 is shaped to match the main plate 1.

Specifically, the steel sheet body 2 can be arranged according to the shape of the main board 1, so that interference with other components is avoided.

In some embodiments, the screw area 3 is near the side of the main board 1.

in some embodiments, the upper surface of the screw region 3 is lower than the upper surface of the steel sheet body 2, and the lower surface of the screw region 3 is lower than the lower surface of the steel sheet body 2.

specifically, the upper surface of the screw area 3 is lower than the upper surface of the steel sheet body 2, so that the upper surface of the screw is not higher than the steel sheet body 2 when the screw is screwed, and the lower surface of the screw area 3 is lower than the lower surface of the steel sheet body 2, so that the screw area 3 can be attached to the main board 1 as much as possible.

in some embodiments, the SMT area 4 is a small steel plate connected to the other end of the steel plate body 2.

in some embodiments, the small steel sheets are assembled on the main board 1 by an SMT process.

Specifically, in the conventional technology, screws are used in the SMT area 4, so that screw holes need to be drilled in both the main board 1 and the steel sheet, and thus, no parts are required to be drilled in both the hole drilling position of the main board 1 and the hole drilling position of the steel sheet.

In some embodiments, the lower surface of the small steel sheet is lower than the lower surface of the steel sheet body 2.

Specifically, the lower surface of the small steel sheet is lower than the lower surface of the steel sheet body 2, so that the small steel sheet can be attached to the main board 1 as much as possible.

To sum up, the utility model comprises a steel sheet body 2 for pressing the BTB on the mobile phone mainboard 1; the screw area 3 is arranged at one end of the steel sheet body 2; the SMT area 4 is arranged at the other end of the steel sheet body 2; and through holes matched with the screw area 3 and the SMT area 4 are respectively arranged on the mainboard 1. By adopting the design, the components can be arranged on the back surface of the small steel sheet, the area of the main board 1 is saved, and the cost can be saved.

The above-described embodiments are merely illustrative of one or more embodiments of the present invention, and the description thereof is more specific and detailed, but the scope of the invention is not limited thereto. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
