[0012] As a further aspect of the present invention, the electric telescopic rods of two adjacent upper and lower layers are arranged alternately.

[0013] As a further aspect of the present invention: a plurality of hot air blowers and cold air blowers are provided on the inner wall of the fixing ring, and the hot air blowers and cold air blowers are respectively arranged at intervals between adjacent electric telescopic rods.

[0014] A detection method based on a connector detection and positioning fixture, characterized by the following detection steps:

[0015] S1: The drive cylinder drives the top plate to rise to the upper part of the fixed ring. The operator places the electrical connector to be tested from the middle of the fixed ring down onto the top plate. The drive cylinder drives the electrical connector to descend to its appropriate testing position.

[0016] S2: The telescopic end of the electric telescopic rod extends synchronously toward the center of the fixed ring, so that the clamping part on the telescopic end of the electric telescopic rod makes full contact with the electrical connector and positions and clamps the electrical connector.

[0033] Please see Figure 1-2 A connector detection and positioning fixture, comprising a base 1;

[0034] The upper end of the base 1 is provided with a circular array of several support rods 2, and the upper end of the support rods 2 is provided with a fixing ring 3;

[0035] Several electric telescopic rods 4 are arranged in a circular array inside the fixed ring 3 facing the center of the fixed ring 3. The telescopic end of each electric telescopic rod 4 extends into the inner ring of the fixed ring 3. A clamping member 5 is provided on the telescopic end of the electric telescopic rod 4.

[0036] A drive cylinder 6 is provided at the lower end of the center point of the fixed ring 3. A top plate 7 is provided on the telescopic end of the drive cylinder 6. The top plate 7 has a cross-shaped structure, and the outer side of the top plate 7 slides against the inner wall of the fixed ring 3.

[0037] During operation, the drive cylinder 6 drives the top plate 7 to rise to the upper part of the fixed ring 3. The operator places the electrical connector to be tested from the middle of the fixed ring 3 onto the top plate 7. The drive cylinder 3 drives the electrical connector to descend to its appropriate testing position. The telescopic end of the electric telescopic rod 4 extends synchronously towards the center of the fixed ring 3, so that the clamping part 5 on the telescopic end of the electric telescopic rod 4 makes full contact with the electrical connector, thereby achieving positioning and clamping of the electrical connector.

[0038] The top plate 7 with its cross-shaped structure slides and engages with the inner wall of the fixing ring 3, enabling it to adapt to electrical connectors on the market and provide support and positioning.

[0039] Example 2: As a further solution of the present invention: screws 8 are respectively provided on the side of the clamping member 5 near the electric telescopic rod 4, and the clamping member 5 is threadedly connected to the telescopic end of the electric telescopic rod 4 through the screws 8;

[0040] The structure of the outer end face of the clamping member 5 on the side away from the electric telescopic rod 4 can be any one of the following: an outward convex arc, an inward concave arc, or a plane.

[0041] Based on the structural shape of the contact position between the electrical connector and the clamping member 5, and considering that the clamping surface of the clamping member 5 can be any one of an outward convex arc, an inward concave arc, or a plane, a clamping member 5 that better fits the position of the electrical connector can be replaced, thereby improving the stability of clamping and positioning.

[0042] As a further aspect of the present invention, the clamping member 5 is made of insulating material.

[0043] This method avoids creating a current loop between the electrical connector and the device during the testing process, thus preventing any impact on the test results and improving the accuracy of the results. Furthermore, the common insulating materials on the market are rubber, plastic, and leather, which also prevents damage to the surface of the electrical connector.

[0044] As a further aspect of the present invention, the electric telescopic rods 4 of two adjacent layers are staggered.

[0045] It facilitates better positioning and clamping of electrical connectors.

[0046] Example 3: As a further embodiment of the present invention: a plurality of hot air blowers 9 and cold air blowers 10 are provided on the inner wall of the fixing ring 3, and the hot air blowers 9 and cold air blowers 10 are respectively arranged at intervals between adjacent electric telescopic rods 4.

[0047] It can change the temperature of the test environment for electrical connectors and detect the working efficiency of electrical connectors at high and low temperatures, thereby effectively improving the testing capability of electrical connectors.

[0048] A detection method based on a connector detection and positioning fixture, characterized by the following detection steps:

[0049] S1: Drive cylinder 6 drives top plate 7 to rise to the upper part of fixed ring 3. The operator places the electrical connector to be tested from the middle of fixed ring 3 onto top plate 7. Drive cylinder 6 drives electrical connector to descend to its appropriate testing position.

[0050] S2: The telescopic end of the electric telescopic rod 4 extends synchronously toward the center of the fixed ring 3, so that the clamping part 5 on the telescopic end of the electric telescopic rod 4 makes full contact with the electrical connector and positions and clamps the electrical connector.

[0051] S3: Connect the electrical connector to an external detector to achieve comprehensive testing of the electrical connector;

[0052] S4: Turn on the hot air blower 9 to test the working efficiency of the electrical connector in a high-temperature environment; by adjusting the hot air blower 9 to blow out hot air at different temperature levels, the working ability and efficiency of the electrical connector at different high temperature levels can be tested.

[0053] S5: Turn on the air cooler 10 to test the working efficiency of the electrical connector in a low-temperature environment; by adjusting the air cooler 10 to blow out cold air at different temperature levels, the working ability and efficiency of the electrical connector at different low-temperature levels can be tested.

[0054] S6: After the test is completed, the telescopic end of the electric telescopic rod 4 retracts, and the drive motor 6 drives the electrical connector to rise through the top plate 7. The operator then removes the electrical connector to complete the test.

[0055] It should also be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
