Detailed Description

In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or be indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or be indirectly connected to the other element.

In the description of the present invention, it is to be understood that the terms "center", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The principles and structure of the present invention will be described in detail below with reference to the accompanying drawings and examples.

As shown in fig. 1, the utility model provides a power adapter, include: casing 1 (the casing that only shows in the figure takes the part of participating in), a pair of participate in 11, PCB board 3, participate in 11 and install in one side of casing 1 and pierce through the casing, install inserted sheet seat 31 on PCB board 3, be equipped with on the inserted sheet seat 31 with participate in the tip complex jack that is located casing 1, during the installation, PCB board 3 lock joint is on the part that casing 1 took the part of participating in, the tip of participating in 11 inserts in the jack and switches on with PCB board 3, do not use the wire to be connected, the stability of being connected between participating in and the PCB board has been guaranteed.

The insert seat 31 includes an insert plate, two supporting pins are disposed on two side edges of the insert plate, and the supporting pins are inserted into the mounting holes preset on the PCB 3, so that the insert seat 31 is conducted with the PCB 3 and fixed on the PCB 3.

In one embodiment, the insertion hole is arranged at the center of the insertion sheet plate, and the edge of the insertion hole is provided with a trumpet-shaped elastic sheet which is curled into the insertion hole, so that the connection between the insertion sheet seat and the insertion pin can be ensured, and the insertion and clamping of the insertion pin are facilitated, so that the structure is more stable.

As shown in fig. 2, in another embodiment, the insertion hole is square, and the edges of the four sides of the insertion hole are respectively provided with two sections of elastic sheets 311 extending along the insertion direction and bent, so that the insertion hole is gradually reduced along the extension direction of the elastic sheets 311, the end of the pin 11 can be conveniently inserted, the conduction between the insertion sheet seat and the pin can be ensured, and the insertion sheet seat 31 is provided with a notch 312 at the joint of two adjacent elastic sheets, thereby facilitating the processing of the elastic sheets and improving the production efficiency. Specifically, the bayonet can be arranged at the end part of the pin, and the end part of the pin can be buckled at the top end of the elastic sheet after being inserted, so that the stability of the whole structure is ensured.

Wherein, when the inserted sheet seat is installed in the PCB board back to the one side of participating in, still be equipped with on the PCB board and be used for passing the through-hole of connecting rod for the jack setting, the tip of participating in 11 passes through pegging graft with inserted sheet seat 31, can reach better stability, accessible and the fixed PCB board of casing bear partial stress, improve holistic durability.

The one end of participating in to be located the casing is perpendicular with the face of PCB board, during the installation, detains PCB board 3 and passes through the screw fixation on the drain pan of participating in 11 in 1 area of casing, makes insertion piece seat 31 and participates in the grafting cooperation, has improved holistic stability greatly.
