Description

Technical Field

[0001] The utility model belongs to the technical field of electronic component process equipment, in particular to an electronic component testing fixture. Background Art

[0002] Various electronic components are the basic components that make up various electronic instruments and electronic equipment. After these electronic components are prepared and formed, their electrical properties need to be measured or tested. Usually, the electronic components have small dimensions and are provided with multiple pins. When testing their electrical properties, it is necessary to introduce electrical signals or electrical energy such as current and voltage into the interior of the electronic components through the pins of the electronic components.

[0003] For example, the patent document with the announcement number "CN220356349U" discloses a fixture for batch power-on screening test of angular displacement sensors, including a fixture plate, an electronic component and a circuit board. The "L"-shaped fixture plate is formed by connecting a bottom plate and a side plate and is integrally formed. Two circuit boards are respectively installed at the center of the bottom plate and the center of the side plate. A plurality of sensor installation grooves are respectively provided on the upper surface of the bottom plate and on the side surface of the side plate close to the bottom plate. A plurality of connecting clips are provided on each circuit board. All the pins of the plurality of connecting clips on each circuit board are respectively electrically connected to a plurality of contact pieces of an electronic component in a one-to-one correspondence. This patented technology realizes the screening test of multiple angular displacement sensors at one time. However, when testing electronic components, alligator clips connected with wires are generally used to introduce electrical signals or electrical energy into the electronic components. Since the external dimensions of the electronic components are small, the external dimensions of the pins of the electronic components are even smaller. The alligator clips are not convenient for clamping the pins of the electronic components, which affects the testing of the electronic components. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an electronic component testing fixture.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides an electronic component testing fixture, comprising an insulating base, a plurality of wiring pieces, a plurality of conductive pins and a plurality of conductive blocks, wherein the surfaces of the conductive blocks are provided with positioning blind grooves, the conductive pins are fixedly connected to the conductive blocks, and the conductive pins penetrate one end of the wiring piece and the insulating base, and the other end of the wiring piece extends outwards.

[0007] The difference between the spacing between at least one pair of adjacent blind positioning grooves and the row spacing between the pins of the electronic component is more than 0.5 mm.

[0008] The depth of the positioning blind groove is less than the height of the electronic component pin.

[0009] The number of the conductive blocks, the number of the positioning blind grooves, and the number of the wiring pieces are equal to the number of the pins of the electronic components and correspond one to one.

[0010] The electronic component testing fixture further comprises an insulating spacer, which is clamped between any two adjacent conductive blocks.

[0011] The number of the conductive blocks is 4.

[0012] The conductive block is in a rectangular parallelepiped shape as a whole.

[0013] The conductive pins may be replaced by bolts.

[0014] The left and right sides of the connecting piece are also bent into a U shape respectively.

[0015] The beneficial effect of the utility model is that: by adopting the technical scheme of the utility model, when the pin of the electronic component is extended into the positioning blind groove, an electrical connection is established between the pin of the electronic component and the conductive block, the conductive pin and the wiring piece, and the electrically connectable outer dimensions of the pin of the electronic component are enlarged by the conductive block and the wiring piece. When the user tests the electronic component, it is only necessary to use an alligator clip to clamp the wiring piece, thereby ensuring smooth testing.

[0020] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0021] like Figures 1 to 3 As shown, the utility model provides an electronic component testing fixture, including an insulating base 1, a plurality of wiring pieces 2, a plurality of conductive pins 3 and a plurality of conductive blocks 4, the surface of the conductive block 4 is provided with a positioning blind groove 5, the conductive pin 3 is fixedly connected to the conductive block 4, and the conductive pin 3 passes through one end of the wiring piece 2 and the insulating base 1, and the other end of the wiring piece 2 extends outward.

[0022] By adopting the technical solution of the utility model, when the pin of the electronic component is extended into the positioning blind groove, an electrical connection is established between the pin of the electronic component and the conductive block, the conductive pin and the wiring piece, and the electrically connectable outer dimensions of the pin of the electronic component are enlarged by the conductive block and the wiring piece. When the user tests the electronic component, it is only necessary to use an alligator clip to clamp the wiring piece, thereby ensuring smooth testing. The utility model has the advantages of simple structure and convenient clamping of electronic components.

[0023] Specifically, the difference between the spacing of at least one pair of adjacent blind positioning grooves 5 and the row spacing of the pins of the electronic component 6 is greater than 0.5 mm. The depth of the blind positioning groove 5 is less than the height of the pins of the electronic component 6. When the utility model is used to clamp the electronic component, the pins of the electronic component are tightly clamped between the adjacent blind positioning grooves, so that the electronic component can be reliably clamped at one time, and the loading and unloading operation is simpler than the prior art.

[0024] In addition, the number of conductive blocks 4, the number of positioning blind grooves 5, the number of connecting pieces 2 and the number of pins of the electronic component 6 are equal and correspond one to one. Preferably, the number of conductive blocks 4 is 4, and the shapes and sizes are completely consistent, and the connection positions between the connecting pieces 2 and the conductive blocks 4 are also completely consistent, so that each conductive block 4 can be interchanged during assembly. The conductive blocks 4 are arranged in a matrix array on the surface of the insulating base 1, and the electronic component test fixture also includes an insulating spacer 7, which is clamped between any two adjacent conductive blocks 4.

[0025] In addition, the conductive block 4 is in the shape of a rectangular parallelepiped as a whole. The conductive pin 3 can be replaced by a bolt, thereby effectively reducing the manufacturing cost of the utility model. The left and right sides of the connecting piece 2 are also bent into a U shape, respectively. This makes it convenient for users to use alligator clips to clamp the connecting piece 2, ensuring that users can smoothly carry out the test work on electronic components.
