Description

A handheld connector testing fixture Technical Field

[0001] This invention belongs to the field of connector testing fixture technology, and specifically relates to a handheld connector testing fixture. Background Technology

[0002] When performing tests on existing wire harness connectors, there are currently no tools or products on the market that can directly detect problems such as improperly inserted connector pins, misaligned pins that cannot be inserted into the female connector, incorrect pin phase sequence, or missing pins. The current solution is to rely on visual inspection by production personnel. However, visual inspection is affected by multiple factors and cannot achieve a 100% pass rate.

[0003] Although the following patents can be found: CN221993503U (a testing fixture for male electrical connectors); CN208399624U (a testing device for electric vehicle connectors); CN213399960U (a testing device and remote control for remote control connectors); CN213750290U (a fixture for easy testing of wire harness connectors).

[0004] The aforementioned patents mostly use the connection status signal between the male and female terminals of the connector to determine whether the connector is effectively connected. That is, they can only determine whether the connector pins are in place, but cannot determine whether the pins are misaligned or whether the pin phase sequence is incorrect. Based on this, a handheld connector testing fixture is proposed. Summary of the Invention

[0005] The main objective of this invention is to provide a handheld connector testing fixture that solves the problem that existing testing fixtures cannot detect whether the pins are misaligned or incorrectly inserted.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a handheld connector testing fixture, comprising a plug-in component, a display component, and a tail cover, the tail cover being sleeved on the top of the display component, the plug-in component comprising a probe fixing block, a probe being fixedly connected to the middle part of the probe fixing block, a probe reset spring being sleeved on the probe, a locking pin being provided on the probe fixing block, a spring detection structure being connected to the bottom of the plug-in component, and the spring detection structure being connected to a logic data processing board via an electrical signal.

[0007] Furthermore, the spring detection structure includes a copper block and a spring. The spring is connected to a logic data processing board via wires. A top rod is connected to the bottom of the spring detection structure. A protective reset spring is provided on the top rod, and a protective sleeve is also provided at the bottom of the top rod.

[0008] Furthermore, the display component includes a logic circuit board, which is connected to a display screen.

[0009] Furthermore, the display component is also connected to a rechargeable battery, which is connected to a charging port, and the display component is also equipped with a detection button.

[0010] Compared with the prior art, the present invention has the following beneficial effects: By setting up a plug-in component and a spring detection structure, when the pin is misaligned, the sheath will be lifted, and the sheath will press the upper spring against the spring detection structure to form a circuit, thus determining that the pin is misaligned; when the pin is properly inserted, the probe will be lifted, and if the probe is not lifted, it is determined that the pin is not in place. This fixture can quickly detect whether the pin is misaligned or incorrectly inserted. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Referring to Figure 1, this invention discloses a handheld connector testing fixture, including a plug-in component 2, a display component 3, and a tail cover 1. The tail cover 1 is sleeved on the top of the display component 3. Referring to Figure 2, the plug-in component 2 includes a probe fixing block 4. A probe 5 is fixedly connected to the middle part of the probe fixing block 4. A probe reset spring 6 is sleeved on the probe 5. Furthermore, a locking pin 7 is also provided on the probe fixing block 4. The testing fixture and the workpiece to be tested are plugged and installed through the locking pin 7 to facilitate testing.

[0018] Furthermore, a spring detection structure is connected to the bottom of the plug-in component 2. The spring detection structure is connected to a logic data processing board via an electrical signal. The spring detection structure can transmit the pin misalignment signal, the pin not fully inserted signal, and the phase sequence detection signal to the logic data processing board. Referring to Figure 3, the spring detection structure includes a copper block 8 and a spring 9. The spring 9 is connected to the logic data processing board via a wire. A top rod is connected to the bottom of the spring detection structure. A protective sleeve reset spring 11 is provided on the top rod. Furthermore, a protective sleeve 10 is also provided at the bottom of the top rod.

[0019] Furthermore, the display component 3 includes a logic operation circuit board, which processes the signals received by the logic data processing board. The logic operation circuit board is connected to a display screen 12, which displays the calculation results of the logic operation circuit board on the display screen 12, making it easy to see the test results intuitively and guiding production personnel to handle abnormalities in a timely manner or save data for uploading to the system. The display component 3 is also equipped with a rechargeable battery, which charges the display component 3. The rechargeable battery is connected to a rechargeable battery charging port. Furthermore, the display component 3 is also equipped with a test button, which can control the switch of this test fixture.

[0020] Explanation of the working principle of the spring contact detection structure: When the pin is misaligned, the pin pushes up the sheath 10, and the sheath 10 pushes the spring contact 9 and the copper block 8 into contact. The signal is transmitted to the logic data processing board through the wire on the spring contact 9. When the pin is inserted into place, the push rod is pushed up, and the push rod presses the spring contact 9 and the copper block 8 into contact. The copper block 8 is set to a high level. The spring contact 9 is soldered with wires, so the electrical signal is transmitted to the logic data processing board through the wires. When the pin phase sequence needs to be detected, first disconnect the high-level signal on the copper block 8, and directly detect the resistance value between each pair of spring contacts that has been set (defined according to the pin number of the connector under test).

[0021] The implementation principle of this invention is as follows: When the pin is misaligned, the sheath 10 will be lifted up, and the sheath 10 will squeeze the upper sheath return spring 10. The sheath return spring 10 will press the upper spring piece 9 against the spring piece detection structure and form a circuit, which means that the pin is misaligned. When the pin is properly inserted, the probe 5 will be lifted up. If the probe 5 is not lifted up, it means that the pin is not in place.
