Description

Technical Field

[0001] This utility model relates to the field of electronic product testing technology, specifically a testing fixture for hard-wired products. Background Technology

[0002] Electronic products are products that rely on electrical energy to function. As these products become more widespread, there are increasingly more and more different kinds of electronic products. The annual shipment volume of electronic products is enormous, and each electronic product must undergo a shipment inspection before leaving the factory.

[0003] An existing patent application (application number 201721729453.3) discloses an electronic product testing device for performing electrical performance tests on electronic products. The device includes a fixed component, a floating adjustment component, and a mounting component for placing test modules. The mounting component is buoyantly mounted on the fixed component via the floating adjustment component, allowing the mounting component and the test modules mounted thereon to collapse and reset in the Z-direction when the electronic product is inserted, and to float and self-reset in the X and Y directions perpendicular to the Z-direction. This invention allows for fine-tuning of the insertion angle of the electronic product under test, greatly reducing device wear and improving testing efficiency. However, it requires connecting the product's wiring with connectors, which is inconvenient, and unreliable wiring can easily lead to unsatisfactory test results or repeated testing. Utility Model Content

[0004] The purpose of this utility model is to provide a test fixture for hard-wired products, so as to solve the problems in the prior art that require the use of wire clamps to connect the connecting wires of the product, which is inconvenient to operate and the unreliable wiring can easily lead to unsatisfactory test results or repeated testing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a test fixture for hard wire products, including a test base, a support platform on the upper side of the test base, a positioning seat on the top of the support platform via a connecting seat, a test clamp inserted inside the positioning seat, a plurality of test insertion seats inside the test clamp, a wire tube at the lower end of the test insertion seat, and a bent positioning tube at the lower side of the wire tube, a test slot in the middle of the support platform, and one end of the bent positioning tube electrically connected to the test terminal of the test slot via a wire.

[0006] Furthermore, the connecting seat is a frustum-shaped seat, and the positioning seat has a first positioning groove on its upper side.

[0007] Furthermore, the positioning seat has a second positioning groove inside, and the test insertion seat is engaged in the second positioning groove.

[0008] Furthermore, the test insert is provided with a wire hole, and one end of the wire hole is shaped like a horn.

[0009] Furthermore, the test insert and the lead conduit are integrally formed, and both the test insert and the lead conduit are made of insulated plastic.

[0010] Furthermore, the bent positioning tube is a metal copper tube, and the inner diameter of the bent positioning tube is larger than the outer diameter of the wire tube.

[0011] Furthermore, the bent positioning tube is an inclined Z-shaped tube or a bent positioning tube with a C-shaped tube or an S-shaped tube inside.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model, through the test clamp, test insertion seat, wire tube and bent positioning tube provided on the upper end of the support platform, enables the rigid lead wire of the product to be inserted into the bent positioning tube, realizing the rapid connection between the rigid lead wire and the test terminal. The positioning stability is high, the disassembly and assembly are convenient, and the product testing time is greatly shortened, which improves both testing efficiency and testing reliability.

[0014] 2. This utility model integrates the test insert and the lead tube, and the test clamp, test insert, and lead tube are all made of insulated plastic. The bent positioning tube is made of metal copper tube, which prevents the lead tube from contacting the metal shell and causing test failure, thus further improving the safety of testing products with hard wire pins.

[0015] 3. This utility model uses a bent positioning tube, which is either an inclined Z-shaped tube or has a C-shaped or S-shaped tube inside. This increases the friction force of the rigid lead wire of the product under test being inserted into the bent positioning tube, thereby improving the stability of the rigid lead wire being inserted into the bent positioning tube.
