Description

Mounting structure of through adapter on PCB circuit board

Technical Field

The utility model relates to a direct adapter technical field, more specifically are a mounting structure of direct adapter on PCB circuit board.

Background

Printed circuit boards ("printed circuit boards") are also known as printed circuit boards, and are providers of electrical connections for electronic components. The printed circuit board is generally denoted as "PCB" and cannot be called "PCB board". Its development has been over 100 years old; the design of the method is mainly layout design; the circuit board has the main advantages of greatly reducing errors of wiring and assembly, and improving the automation level and the production labor rate. The circuit board can be divided into a single-sided board, a double-sided board, a four-layer board, a six-layer board and other multi-layer circuit boards according to the number of the layers of the circuit board. Since printed circuit boards are not typical end products, they are somewhat confusing in the definition of names such as: the motherboard for a personal computer is called a motherboard and cannot be directly called a circuit board, and although the circuit board exists in the motherboard, the motherboard is different from the motherboard, so that the two aspects cannot be said to be the same when evaluating the industry. For another example: because of the integrated circuit components mounted on the circuit board, the news media is called an IC board, but it is not substantially identical to a printed circuit board. By printed circuit board we generally say bare board-i.e. a circuit board without upper components.

The conventional PCB needs to be provided with a direct adapter to connect components, but the conventional adapter can integrally rotate and cannot be screwed tightly during installation. Therefore, a new technical solution needs to be provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a mounting structure of direct adapter on PCB circuit board has solved and has need to install the connection that direct adapter carried out components and parts on the current PCB board among the prior art, but traditional adapter can wholly rotate together when the installation, screws up the problem not tight.

In order to achieve the above object, the utility model provides a following technical scheme: a mounting structure of a through adapter on a PCB circuit board comprises: the PCB board body, the outside that the surface of PCB board body was equipped with screw hole and screw hole sets up the draw-in groove, the draw-in groove is the inside that rectangle structure set up and screw hole and is equipped with the adapter body, the surface of adapter body is equipped with long screw thread and short screw thread, the surface of adapter body is equipped with fixed plate and is the setting of hexagon structure, the fixed plate is located mutual gomphosis between short threaded junction and fixed plate and the draw-in groove, long threaded surface is equipped with threaded connection between fly leaf and the long screw thread.

As a preferred embodiment of the present invention, the long thread is twice the length of the short thread.

As a preferred embodiment of the present invention, the side of the movable plate is provided with a washer and the inner diameter of the washer is larger than the adapter body.

As a preferred embodiment of the utility model, the inside that the both ends of adapter body were equipped with recess and recess is equipped with the connecting hole, the connecting hole runs through the adapter body.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the utility model discloses screw hole outside on the surface of PCB board body sets up the draw-in groove, and the surface of its adapter body sets up the fixed plate, and mutual gomphosis has restricted the rotation of adapter body between fixed plate and the draw-in groove, rotate the fly leaf make its long thread surface sliding block and with the PCB board between the mutual contact to fix, this kind of setting has avoided the adapter can wholly rotate when the installation, causes the condition emergence of screwing up not tightly.
