For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Please refer to Figures 1 to 3 As shown, an electric connector plug force measuring pen comprises:

[0028] A grip rod 1, wherein the grip rod 1 is coaxially structured with a mounting cavity 2 penetrating at both ends;

[0029] The top connection mechanism comprises a positioning portion 3 provided at one end of the installation cavity 2 and a top connection portion 4 provided in the sliding cavity, wherein the end of the top connection portion 4 opposite to the positioning portion 3 serves as a needle tip top connection end;

[0030] The limiting mechanism 5 is arranged at the end of the installation cavity 2 opposite to the positioning portion 3, the needle tip top contact end extends into the limiting mechanism 5, and the end of the limiting mechanism 5 opposite to the needle tip top contact end is constructed with an insertion channel 6, and the insertion channel 6 is used for the needle tip to pass through and abut against the needle tip top contact end.

[0031] In this way, when measuring force, the electrical connector pin is inserted from the insertion channel 6, and the pin abuts against the needle tip contact end, and the pin is continuously pushed inward with force, so as to utilize the abutment between the needle tip contact end and the pin to simulate the state of the pin being subjected to external pressure force, so as to determine whether the pin can meet the requirements of not bending or deflecting through the state of the pin after abutting against the needle tip contact end.

[0032] Furthermore, a positioning channel 7 is provided on the side wall of the gripping rod 1, and the positioning channel 7 is communicated with the mounting cavity 2. A clamping bolt is installed in the positioning channel 7, and the positioning portion 3 and the limiting mechanism 5 are respectively installed and positioned by different clamping bolts.

[0033] In this way, the positioning portion 3 and the limiting mechanism 5 are fixed by tightening the bolts, which can facilitate the disassembly of the entire device.

[0034] At the same time, the positioning portion 3 is a top connection block 14 coaxially arranged in the installation cavity 2, the outer wall of the top connection block 14 is threadedly connected to the inner wall of the installation cavity 2, and the top connection block 14 is coaxially configured with a driving ridge groove 8 at one end facing the connecting port of the installation cavity 2, and the top connection block 14 is coaxially configured with an insertion groove 9 at one end facing the cavity body of the installation cavity 2.

[0035] In addition, the top-connecting portion 4 includes a damping mechanism abutting against the positioning portion 3, a sliding rod 10 is coaxially mounted on the end of the damping mechanism opposite to the positioning portion 3, the outer wall of the sliding rod 10 is in contact with the inner wall of the mounting cavity 2, and a push rod 11 serving as the needle tip top-connecting end is coaxially mounted on the end of the sliding rod 10 opposite to the damping mechanism, and the bottom end of the push rod 11 abuts against the upper through end of the insertion channel 6.

[0036] Moreover, the damping mechanism includes a positioning rod 12 slidably arranged in the insertion groove 9, the bottom end of the positioning rod 12 is connected to the sliding rod 10, and a compression spring 13 is sleeved on the positioning rod 12, and the two ends of the compression spring 13 are respectively abutted against the top block 14 and the sliding rod 10.

[0037] In this way, during the use of the present application, after the pin is inserted, the needle tip contact end is pushed upward under the action of external force, which can cause the compression spring 13 to be compressed. As long as the insertion depth of the pin is fixed in each measurement, the compressed length of the compression spring 13 is also the same, thereby ensuring that the external force applied to the pin is the same in each measurement.

[0038] Furthermore, when the force applied to the pin needs to be changed, it is only necessary to rotate the top contact block 14 and move the top contact block 14 downward to compress the compression spring 13, so that when the pin is inserted to the same depth, the pin can receive a greater restoring force from the compression spring 13. Similarly, if it is desired to reduce the abutment force applied to the pin during the test, it is only necessary to rotate the top contact block 14 and move the top contact block 14 upward to increase the length of the compression spring 13, so that when the pin is inserted to the same depth, the pin can receive a smaller restoring force from the compression spring 13.

[0039] The aforementioned compression spring 13 refers to a spring that is always in a compressed state.

[0040] Furthermore, the limiting mechanism 5 is a limiting block coaxially arranged in the mounting cavity 2, and the limiting block includes a mounting block 15 threadedly connected to the inner wall of the mounting cavity 2, and an insertion block 16 is coaxially installed at the bottom end of the mounting block 15, and the insertion channel 6 is coaxially arranged in the insertion block 16 and one end passes through the bottom end of the insertion block 16, and a limiting channel 17 is coaxially constructed in the mounting block 15, and the limiting channel 17 is connected to the insertion channel 6, and the inner diameter of the insertion channel 6 is smaller than the inner diameter of the limiting channel 17, and the needle tip top connection end extends into the limiting channel 17 and covers the connecting port of the insertion channel 6.

[0041] In this way, the pin is inserted into the insertion channel 6, and then moves upward to abut against the push rod 11 in the limiting channel 17 as the pin tip contact end. Thus, the push rod 11 is pushed up to perform the test. And the entire test can be adapted to pins of different diameters by having limit blocks with different inner diameters of the insertion channel 6. Thus, the adaptability of the entire test equipment is improved.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
