Detailed Description
The utility model is described in further detail below with reference to the drawings and examples.
The utility model provides a test fixture for a crystal hood packaging relay, which is realized by using a spring probe, as shown in fig. 1, wherein a PCB (printed circuit board) is used as a main carrier, and a spring probe area, a PCB wiring area and an external interface area are arranged on the PCB.
As shown in fig. 2, in the spring probe area, spring probe welding points 4 are set according to the size, the number of pins and the definition of the crystal cover relay, and spring probes 1 are welded on the spring probe welding points, so that the spring probes can be contacted with the pins of the crystal cover relay. In addition, a 1-foot identification point position 2 can be arranged in the spring probe region, and the crystal cover packaging relay is aligned with the spring probe according to the 1-foot identification point position 2.
On the external interface area an interface connector 5 is soldered, which interface connector is used for cross-linking with the test equipment. Misplug prevention designs 6, such as male-female structures or T-connectors, can also be used on the external interface area, such as where the test equipment is inserted in a direction that is not aligned and cannot be effectively inserted.
In the PCB wiring area, the spring probe welding point is communicated with the interface connector 5 through metal interconnection wiring to form a test fixture. A relay product model name identifier 3 can also be set in the PCB routing area. Because the crystal cover relay of a product model corresponds to different test tools due to different sizes, pin numbers, definitions and the like, the product type of the crystal cover relay applicable to the test tools can be identified through the name identification 3 of the relay product model.
