Description

Technical Field

[0001] This utility model belongs to the field of PIN testing, specifically, it relates to an empty PIN testing fixture. Background Technology

[0002] With the popularity of wearable electronic products, the application of elastic and stretchable PogoPin is becoming more and more widespread. Electrical testing of different PogoPin usually requires specialized testing instruments or equipment.

[0003] Patent application CN213658881U discloses a PogoPin testing fixture. Paragraph 0018 of the specification discloses: a base block and a pressure block disposed on the base block. The pressure block includes an upper pressure block. The upper pressure block has side plates on its left and right sides for limiting and fixing its position. A first flange protrudes outward from the front side of the upper pressure block. Screw holes are provided in the middle of the left and right sides of the upper pressure block. Each side plate has a through hole, and the through hole and the screw hole on the same side are positioned corresponding to each other. A screw is installed by connecting the screw hole after passing through the through hole. Each side plate has a stepped structure that protrudes outward from the side facing the upper pressure block to position the upper pressure block and fix the compression stroke.

[0004] However, in practical applications, the bottom block needs to be fixed to the bottom of the upper pressure block by the two side plates, and the upper pressure block needs to be fixed between the two side plates by one end of the screw. Since there are no screws between the bottom block and the side plates, the bottom block is prone to falling off between the two side plates during use, which will make the bottom block unusable.

[0005] To address these shortcomings, a blank PIN testing fixture is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an empty PIN testing fixture.

Detailed Implementation

[0028] The present invention will now be described in further detail with reference to the accompanying drawings.

[0029] Please see Figure 1-4 As shown, this embodiment provides an empty PIN testing fixture, including two side plates 104, an upper pressure block 100 and a bottom block 102 located below the upper pressure block 100.

[0030] Two guard plates 200 are provided. Two positioning plates 203 are fixedly fitted on one side of the guard plate 200. Two adjacent positioning plates 203 are snap-fitted together at one end. Two L-shaped posts 202 are fixedly fitted at the upper end of the positioning plate 203. The inner sidewall of the L-shaped post 202 fits with the corner of the upper pressure block 100. A first L-shaped plate 208 is fixedly fitted at the lower end of the positioning plate 203. A second L-shaped plate 209 is fixedly fitted on both sides of the first L-shaped plate 208. One end of the second L-shaped plate 209 and one end of the first L-shaped plate 208 fit with the bottom block 102.

[0031] Working principle:

[0032] First, place the upper pressure block 100 and the bottom block 102 between the two side plates 104. At this time, the upper pressure block 100 is located on the upper side of the bottom block 102. Then, place the two guard plates 200 on one side of the side plate 104 respectively. The upper end of the guard plate 200 drives the L-shaped column 202 to be placed at the corner of the upper pressure block 100. The lower end of the guard plate 200 drives the first L-shaped plate 208 and the second L-shaped plate 209 to be placed on the surface of the bottom block 102. Then, the two adjacent positioning plates 203 are engaged to complete the fixing of the bottom block 102 and the upper pressure block 100.

[0033] The positioning plate 203 is set so that the guard plate 200 fixes the upper pressure block 100 and the bottom block 102 between the two side plates 104 under the action of the positioning plate 203, which reduces the problem of the upper pressure block 100 and the bottom block 102 falling off between the two side plates 104, improves the testing effect of the upper pressure block 100 and the bottom block 102, and makes the testing process of the upper pressure block 100 and the bottom block 102 more convenient.

[0034] To make the sliding process of the positioning plate 203 on one side of the side plate 104 more stable in this embodiment, the following improvements are made, such as... Figure 1-4 As shown, in this embodiment, a first flange 101 is fixedly fitted to one side of the upper pressure block 100, a second flange 103 is fixedly fitted to one side of the bottom block 102, and placement grooves 105 are provided on both sides of the side plate 104. The positioning plate 203 is located inside the placement groove 105. A threaded hole 204 is provided at one end of the positioning plate 203, and a threaded rod 205 is threadedly fitted between two adjacent threaded holes 204. The threads on both sides of the threaded rod 205 are in opposite directions, and a rubber pad 206 is fixedly fitted to the circumference of the middle part of the threaded rod 205. A connecting rod is fixedly fitted to the upper end of the guard plate 200. One end of the connecting plate 201 and the L-shaped column 202 are fixedly fitted to one side of the connecting plate 201. The lower end of the guard plate 200 is fixedly fitted with the connecting block 207. One end of the first L-shaped plate 208 is fixedly fitted to one end of the connecting block 207. Multiple first rubber protrusions are evenly distributed and fixedly fitted on the inner side wall of the L-shaped column 202. One end of the first rubber protrusion is fitted with the surface of the upper pressure block 100. Multiple second rubber protrusions are evenly distributed and fixedly fitted on one side of the first L-shaped plate 208 and the second L-shaped plate 209. One end of the second rubber protrusion is fitted with the surface of the bottom block 102.

[0035] In this embodiment, the upper pressure block 100 and the bottom block 102 are first placed between the two side plates 104. Then, the two guard plates 200 are placed on one side of the two side plates 104 respectively. The guard plates 200 drive the positioning plate 203 to be placed inside the placement groove 105. The upper end of the guard plate 200 drives the L-shaped column 202 to be placed at the corner of the upper pressure block 100 through the connecting plate 201. The lower end of the guard plate 200 drives the first L-shaped plate 208 to move through the connecting block 207. The first L-shaped plate 208 drives... The second L-shaped plate 209 moves, and one end of the second L-shaped plate 209 and one end of the first L-shaped plate 208 move to the surface of the bottom block 102. Then the rubber pad 206 is rotated, and the rubber pad 206 drives one end of the threaded rod 205 to be threaded into the inside of the threaded hole 204. Since the threads on both sides of the threaded rod 205 are opposite, the two positioning plates 203 slide close to each other and the guard plate 200 is positioned on one side of the side plate 104 by the positioning plates 203, thereby completing the fixing of the upper pressure block 100 and the bottom block 102.

[0036] The placement groove 105 facilitates the placement of the positioning plate 203 inside the side plate 104, and guides the sliding direction of the positioning plate 203 through the placement groove 105, reducing the problem of tilting of the positioning plate 203 during sliding and improving the stability of the positioning plate 203 during sliding.
