Description

Depression bar pressing spring probe structure

Technical Field

The utility model relates to a PCB board production technical field especially relates to a layering pushes down spring probe structure.

Background

Pcb (printed Circuit board), which is called printed Circuit board for short, is an important electronic component that is printed and spatially arranged for mounting electronic components. The surface mounting technology is a circuit mounting technology in which a surface-mounted component without pins or short leads is mounted on the surface of a PCB and soldered or the like.

In the process of mounting, welding and other processes, the electronic components need to be stably placed on the PCB and fixed. At present, a pressing strip and a lower cover plate are jointly pressed on an electronic component in the production process to prevent the electronic component from moving, however, when the pressing strip presses the component with small volume, the pressing is incomplete, the component is easy to shift, too many defective products are caused, time and labor are wasted in rework, and the production cost is increased.

SUMMERY OF THE UTILITY MODEL

In order to overcome the not enough of above-mentioned technique, the utility model aims at providing a layering is pressed spring probe structure down, with components and parts on the PCB board spacing, fixed better, prevent effectively that components and parts from shifting, improved the production qualification rate, effective reduce cost.

The utility model adopts the technical proposal that: the utility model provides a layering is spring probe structure of pushing down, includes telescopic link, sleeve, spring, interior pole, the cross section of telescopic link is regular hexagon face, the telescopic link is served and has been seted up the elongated slot, other end and interior pole fixed connection, telescopic one end is fixed to be provided with hangs the arm, and the other end is fixed to be provided with the spring buckle, hang be provided with on the arm with telescopic link assorted regular hexagon hole, the telescopic link is worn to establish on hanging the arm through this regular hexagon hole, the spring sets up in the sleeve, spring one end is supported and is pasted on the telescopic link, and the other end is supported and is pasted on the spring buckle, interior pole stretches out outside the sleeve after passing the spring.

Furthermore, the elongated slot is a cuboid-shaped slot.

Furthermore, the hanging arm is annular, and an arc on one side of the hanging arm is concave inwards to form a rectangular plane.

Compared with the prior art, the utility model discloses following beneficial effect has: a layering pushes down spring probe structure, the elongated slot is spacing with components and parts on the PCB board better, the telescopic link is fixed with components and parts ground pressure better under the effect of spring, effectively prevents components and parts aversion, has improved the production qualification rate, effective reduce cost.

the labels in the figure are: 1. the telescopic rod 2, the hanging arm 201, the rectangular plane 3, the sleeve 4, the spring 5, the spring buckle 6, the inner rod 7 and the long groove.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 to 4, a depression bar spring probe structure that pushes down, including telescopic link 1, sleeve 3, spring 4, interior pole 6, the cross section of telescopic link 1 is the regular hexagon face, telescopic link 1 is served and has been seted up elongated slot 7, other end and interior pole 6 fixed connection, the fixed arm 2 that hangs that is provided with in one end of sleeve 3, the other end is fixed and is provided with spring buckle 5, hang and be provided with on the arm 2 with 1 assorted regular hexagon hole of telescopic link, telescopic link 1 wears to establish on hanging arm 2 through this regular hexagon hole, spring 4 sets up in

sleeve

3, 4 one end of spring are supported and are pasted on telescopic link 1, and the other end supports and paste on spring buckle 5, interior pole 6 stretches out outside sleeve 3 after passing spring 4.

The long groove 7 is a cuboid groove.

The hanging arm 2 is annular, and the arc on one side of the hanging arm 2 is concave inwards to form a rectangular plane 201, so that the hanging arm 2 does not rotate and does not shift after the hanging arm 2 is placed in a hole in the pressing strip.

The utility model discloses the use does: a limiting hole matched with the shape of the hanging arm 2 is formed in the pressing bar, and the hanging arm 2 is clamped in the limiting hole and does not move after the telescopic rod 1 penetrates through the limiting hole; then pressing the pressing strip on the PCB, pressing and fixing the components on the PCB by the telescopic rod 1 under the pushing action of the elastic force of the spring 4, clamping the components by the long groove 7, limiting the long groove 7, preventing the components from shifting, and further ensuring the qualification of the processes of mounting and welding the components.

Can highly use the spring 4 of different length according to the components and parts of difference, make the utility model discloses the suitability reinforcing.

The above embodiments are based on the technical solution of the present invention, and detailed implementation and specific operation processes are given, but the present invention is not limited to the above embodiments.
