The terms "comprising" or "including" are an open-ended expression, meaning that the element preceding "comprising" or "including" encompasses the element following "comprising" or "including" and its equivalents, but this does not preclude the element preceding "comprising" or "including" from also including other elements. In this invention, the term "several" means two or more.

[0020] Please refer to Figures 1 to 10As shown, this invention discloses a testing fixture for detecting the continuity of cables. The cable has multiple conductive wires, and the fixture detects the continuity of each conductive wire. The testing fixture includes a clamping assembly 1, a conductor 2, and a probe 3. The clamping assembly 1 clamps and fixes the cable. The clamping assembly 1 includes a first clamping member 11 and a second clamping member 12, which are rotatably connected. In use, the opening or closing of the first clamping member 11 and the second clamping member 12 is achieved by adjusting the rotation of the first clamping member 11 around the second clamping member 12.

[0021] See Figure 4 The first clamping member 11 includes a first clamping arm 112 and a first clamping portion 111 connected to the first clamping arm 112. The second clamping member 12 includes a second clamping arm 122 and a second clamping portion 121 connected to the second clamping arm 122. The first clamping arm 112 and the second clamping arm 122 are rotatably connected. Along the height direction HH of the testing fixture, the first clamping portion 111 is located above the second clamping portion 121. The first clamping member 11 and the second clamping member 12 are made of white plastic steel, which is lightweight and easy to handle.

[0022] In some implementations, see Figure 6 The first clamping arm 112 has a first receiving groove 1121 and a shaft hole 1122. The second clamping arm 122 has a protrusion 1221 and a connecting shaft 1222 on the protrusion 1221. The protrusion 1221 is at least partially located in the first receiving groove 1121. The connecting shaft 1222 extends into the shaft hole 1122 and can rotate within the shaft hole 1122 to achieve a rotatable connection between the first clamping arm 112 and the second clamping arm 122.

[0023] See also Figure 6 The clamping assembly 1 includes an elastic element 13. One end of the elastic element 13 is connected to the first clamping arm 112, and the other end of the elastic element 13 is connected to the second clamping arm 122. The elastic element 13 provides a clamping force to the first clamping part 111 and the second clamping part 121.

[0024] See Figure 9 The first clamping part 111 includes a clamping body 1111 and a protective pad 1112 connected to the clamping body 1111. The protective pad 1112 is wrapped around the surface of the clamping body 1111 facing the second clamping part 121 by conductive cloth. The protective pad 1112 protects the cable and reduces cable deformation; the conductive cloth wrapping the protective pad 1112 around the clamping body 1111 prevents the protective pad 1112 from falling off or wearing out after repeated use. In this embodiment, the protective pad 1112 is made of foam. Since foam is relatively soft, the addition of conductive cloth can achieve effective compression between the foam and the second clamping part 121.

[0025] In some implementations, see also Figure 9 The clamping body 1111 is integrally formed with the first clamping arm 112. The clamping body 1111 is provided with a second receiving groove 1110. The opening of the second receiving groove 1110 faces the second clamping part 121. The protective pad 1112 is installed in the second receiving groove 1110 to increase the contact area between the protective pad 1112 and the clamping body 1111 and improve the connection stability.

[0026] In the embodiments illustrated in the present invention, see... Figure 2 The first clamping member 11 includes a first sub-clamping member 11a and a second sub-clamping member 11b, both of which include a first clamping portion 111. The second clamping member 12 includes a third sub-clamping member 12a and a fourth sub-clamping member 12b, both of which include a second clamping portion 121. The first sub-clamping member 11a is rotatably connected to the third sub-clamping member 12a, and the second sub-clamping member 11b is rotatably connected to the fourth sub-clamping member 12b. The first end of the cable is clamped between the first clamping portion 111 of the first sub-clamping member 11a and the second clamping portion 121 of the third sub-clamping member 12a, and the second end of the cable is clamped between the first clamping portion 111 of the second sub-clamping member 11b and the second clamping portion 121 of the fourth sub-clamping member 12b.

[0027] In some embodiments, the first sub-clamping member 11a and the second sub-clamping member 11b are spaced apart along the length direction of the clamping assembly 1, and correspondingly, the third sub-clamping member 12a and the fourth sub-clamping member 12b are spaced apart along the length direction of the clamping assembly 1. The outer end face of the first clamping portion 111 of the first sub-clamping member 11a is opposite to the outer end face of the first clamping portion 111 of the second sub-clamping member 11b, and correspondingly, the outer end face of the second clamping portion 121 of the third sub-clamping member 12a is opposite to the outer end face of the second clamping portion 121 of the fourth sub-clamping member 12b. Of course, in other embodiments, the first sub-clamping member 11a and the second sub-clamping member 11b may also be spaced apart along the width direction of the clamping assembly 1, and correspondingly, the third sub-clamping member 12a and the fourth sub-clamping member 12b may be spaced apart along the width direction of the clamping assembly 1. In this case, the outer end face of the first clamping portion 111 and the outer end face of the second clamping portion 121 are on the same plane.

[0028] Multiple clamping components 1 are provided to detect multiple conductive wires of the cable. The multiple clamping components 1 are arranged at intervals along their width direction. In the embodiment illustrated in the present invention, the cable has five conductive wires, and five clamping components 1 are provided, each clamping component 1 detecting one conductive wire. During detection, the first end of each conductive wire is clamped between the first clamping portion 111 of the first sub-clamping member 11a and the second clamping portion 121 of the third sub-clamping member 12a, and the second end of each conductive wire is clamped between the first clamping portion 111 of the second sub-clamping member 11b and the second clamping portion 121 of the fourth sub-clamping member 12b.

[0029] Conductor 2 is made of copper. Conductor 2 is located in the second clamping part 121. For details, see [link to details]. Figure 4 The conductor 2 includes a first portion 21 and a second portion 22 connected to the first portion 21. The first portion 21 is located between the first clamping portion 111 and the second clamping portion 121, and the second portion 22 extends out of the space between the first clamping portion 111 and the second clamping portion 121. The first portion 21 is configured to be electrically connected to a cable, and the second portion 22 is configured to be electrically connected to the probe 3.

[0030] See Figure 5 The first part 21 includes a first surface 211, and the second part 22 includes a second surface 221. The first surface 211 is configured to contact the cable, and the second surface 221 is configured to contact the probe 3. Both the first surface 211 and the second surface 221 are planar. The conductor 2 is made of copper sheet, and the first surface 211 and the second surface 221 are located on the same plane. In related technologies, the probe 3 contacts the circular surface of the conductive wire for detection, which is not easy to form a contact and affects the accuracy of the test. In this invention, the probe 3 contacts the second part 22, realizing the electrical connection between the probe 3 and the cable; the second surface 221 is planar, which facilitates the formation of an electrical connection between the probe 3 and the second part 22, improving the accuracy of the test.

[0031] Probe 3 connects to a circuit tester to test the continuity of the circuit. It can also perform impedance testing. (See also...) Figure 10 The probe 3 includes a detection surface 31, through which the probe 3 contacts the second surface 221. The area of ​​the second surface 221 is larger than the area of ​​the detection surface 31. This arrangement facilitates the formation of an electrical connection between the probe 3 and the second part 22.

[0032] In some implementations, see Figure 5The second clamping portion 121 includes a third surface 1211, which includes a first partial surface 121a and a second partial surface 121b. The projection of the first clamping portion 111 along the height direction HH of the detection fixture falls on the first partial surface 121a. That is, along the width direction of the clamping assembly 1, the width of the first clamping portion 111 is smaller than the width of the second clamping portion 121. The first portion 21 is disposed on the first partial surface 121a, and the second portion 22 is disposed on the second partial surface 121b.

[0033] See Figure 3 The first clamping portion 111 includes a first side surface 1113, and a first space 100 is formed between the first side surface 1113 and the second surface 221 of the second portion 22. The probe 3 extends into the first space 100 and contacts the second portion 22. By setting the width of the first clamping portion 111 to be smaller than the width of the second clamping portion 121, a first space 100 is formed between the first clamping portion 111 and the second clamping portion 121, and the first space 100 serves as the movement space for the probe 3. The first side surface 1113 includes at least the side surface of the conductive cloth.

[0034] In some implementations, see Figure 5 The second clamping part 121 includes a groove 1210 recessed in the third surface 1211, and the conductor 2 is disposed in the groove 1210. The groove 1210 communicates with the first space 100. Along the height direction HH of the detection fixture, both the first surface 211 and the second surface 221 are flush with the third surface 1211. By keeping the surface of the conductor 2 flush with the surface of the second clamping part 121, bending of the cable is avoided when it is placed on the conductor 2.

[0035] In the embodiments illustrated in the present invention, see... Figure 5 Conductor 2 includes a first conductor 21a and a second conductor 21b, which are spaced apart. The first conductor 21a includes a first portion 21 and a second portion 22 connected to the first portion 21. The second conductor 21b includes a first portion 21 and a second portion 22 connected to the first portion 21. The first portions 21 of the first conductor 21a and the second conductor 21b are configured to be electrically connected to the same conductive line. See also... Figure 2 The probe 3 includes a first probe 3a and a second probe 3b. The second part 22 of the first conductor 21a is configured to be electrically connected to the first probe 3a, and the second part 22 of the second conductor 21b is configured to be electrically connected to the second probe 3b. Since the first probe 3a and the second probe 3b are connected in parallel, it is only necessary to ensure that either the first probe 3a or the second probe 3b is in contact with the second part 22 to achieve continuity or open circuit detection of the cable.

[0036] The second clamping portion 121 of the third sub-clamping member 12a is provided with a first conductor 21a and a second conductor 21b, and the second clamping portion 121 of the fourth sub-clamping member 12b is also provided with a first conductor 21a and a second conductor 21b. The first end of the conductive wire is electrically connected to the first conductor 21a and the second conductor 21b provided in the third sub-clamping member 12a, and the second end of the same conductive wire is electrically connected to the first conductor 21a and the second conductor 21b provided in the fourth sub-clamping member 12b.

[0037] See Figure 4 The conductive cloth is wrapped around the protective pad 1112 at a first position to form a first wrapping ring 1114, and the conductive cloth is wrapped around the protective pad 1112 at a second position to form a second wrapping ring 1115. The first wrapping ring 1114 and the second wrapping ring 1115 are spaced apart. See also Figure 7 The first wrapping ring 1114 includes a first end face and a second end face, and the first end face and the second end face are at a first distance W1 along the length direction of the clamping assembly 1; the second wrapping ring 1115 includes a third end face and a fourth end face, and the third end face and the fourth end face are at a second distance W2 along the length direction of the clamping assembly 1; the first distance W1 and the second distance W2 are equal. The first conductor 21a includes a fifth end face and a sixth end face, and the fifth end face and the sixth end face are at a third distance W3 along the length direction of the clamping assembly 1; the second conductor 21b includes a seventh end face and an eighth end face, and the seventh end face and the eighth end face are at a fourth distance W4 along the length direction of the clamping assembly 1; the third distance W3 and the fourth distance W4 are equal. The first distance W1 is not less than the third distance W3, and through the effective contact between the conductive cloth and the cable, the protective pad 1112 and the second clamping part 121 are effectively pressed together.

[0038] See Figure 2 The testing fixture includes a first base 4 and a second base 5. The first base 4 has a mounting groove 120, and a second clamping member 12 is disposed in the mounting groove 120. The third surface 1211 of the second clamping part 121 is located outside the mounting groove 120. The second base 5 includes a base plate 51, a first side plate 52 connected to one side of the base plate 51, and a second side plate 53 connected to the other side of the base plate 51. The base plate 51, the first side plate 52, and the second side plate 53 form a second space 50. The first side plate 52 has a first guide groove 520, and the second side plate 53 has a second guide groove 530. Both the first guide groove 520 and the second guide groove 530 communicate with the second space 50. The first base 4 is inserted into the second space 50 along the first guide groove 520 and the second guide groove 530, respectively. This arrangement facilitates the assembly of the first base 4 onto the second base 5, and the first guide groove 520 and the second guide groove 530 serve as a foolproof mechanism.

[0039] See also Figure 2The testing fixture includes a movable base 6, on which a probe 3 is fixed. A guide rod 54 is fixed on a second base 5, and the movable base 6 has a through hole through which the guide rod 54 passes. The movable base 6 moves along the length of the guide rod 54 to achieve contact or release between the probe 3 and the conductor 2. The length direction of the guide rod 54 is parallel to the height direction of the testing fixture.

[0040] The testing fixture includes a driving component and a mounting frame for fixing the driving component. The driving component is connected to the movable seat 6, and controls the movement of the movable seat 6 along the length direction of the guide rod 54. The driving component can be a cylinder. The driving component, the mounting frame, and the connection method between the driving component and the mounting frame are all prior art and are not illustrated in this invention.

[0041] The present invention also discloses a method for using a testing fixture, comprising the following steps: Step S1: Provide the testing fixture; Step S2: Place the cable between the first clamping part 111 and the second clamping part 121, and adjust the first clamping part 111 and the second clamping part 121 to close, so that the cable is clamped between the first clamping part 111 and the first part 21 of the conductor 2. Specifically, the first end of the conductive wire is placed between the first clamping part 111 of the first sub-clamping member 11a and the second clamping part 121 of the third sub-clamping member 12a, and the second end of the conductive wire is placed between the first clamping part 111 of the second sub-clamping member 11b and the second clamping part 121 of the fourth sub-clamping member 12b, so that the first end of the conductive wire is in contact with the first conductor 21a and the second conductor 21b at the same time, and the second end of the conductive wire is in contact with the first conductor 21a and the second conductor 21b at the same time.

[0042] Step S3: Control the probe 3 to contact the second part 22 of the conductor 2. Specifically, control the detection surface 31 of the probe 3 to contact the second surface 221 of the second part 22 to achieve electrical connection between the probe 3 and the conductor 2.

[0043] The present invention achieves electrical connection between the probe 3 and the cable by forming an electrical connection between the cable and the first part 21 of the conductor 2, and forming an electrical connection between the probe 3 and the second part 22 of the conductor 2, thereby realizing the continuity and open circuit detection of the cable. Compared with the probe 3 directly contacting the circular surface of the conductor, the second part 22 of the present invention is convenient to contact the probe 3, which is conducive to forming a stable electrical connection and improving the accuracy of the test.
