Abstract

A testing device with enhanced accessibility for repair and replacement purposes includes a base, an upper seat, a test board and a needle seat. The upper seat is mounted on the base. The test board is sandwiched between the base and the upper seat. A receiving groove is defined on the upper seat. The receiving groove extends through the upper seat to partially expose the test board. The needle seat is detachably fixed to the upper seat. A lower part of the needle seat is received in the receiving groove and abuts against the test board. An upper portion of the needle seat protrudes from the upper seat and is configure for connecting connection terminals of a product to be tested.

Claims

1. A testing device, comprising:

a base;

an upper seat mounted on the base, wherein a receiving groove is defined on the upper seat;

a test board sandwiched between the base and the upper seat; and

a needle holder detachably fixed to the upper seat;

wherein the receiving groove extends through the upper seat to partially expose the test board, a lower part of the needle holder is received in the receiving groove and abuts against the test board, and an upper portion of the needle holder protrudes from the upper seat and is configured for connecting connection terminals of a product to be tested.

2. The testing device of claim 1, wherein the receiving groove is U-shaped, and is a concavity between adjacent side surfaces of the upper seat, the receiving groove penetrates the upper seat.

3. The testing device of claim 1, wherein the needle holder comprises a fixing seat and a needle assembly, the needle assembly is fixed to the upper seat by the fixing seat.

4. The testing device of claim 3, wherein the receiving groove is stepped, and the fixing seat is fixed to a ladder surface in the receiving groove.

5. The testing device of claim 4, wherein the needle assembly comprises a fixing member, an abutting member, and a protruding member;

the fixing member is fixed to a lower side of the fixing seat, the protruding member and the abutting member are mounted on opposite sides of the fixing member, the protruding member is located on an upper side of the fixing seat, and the abutting member is located on the test board.

6. The testing device of claim 5, wherein an upper side of the fixing member comprises a protruding positioning block, and a lower side of the protruding member has a positioning groove as a concavity, the positioning block protrudes through the fixing seat and is received in the positioning groove.

7. The testing device of claim 5, wherein each of the protruding member, the fixing member, and the abutting member comprises through holes, the through holes of the fixing member and the through holes of the abutting member are correspondingly positioned to the through holes of the protruding member.
