[0002] The TDR impedance tester is a device used to measure the characteristic impedance of cables, printed circuit board traces and other transmission lines. It sends a pulse signal with a fast rise time to the line under test. When the pulse signal encounters a change in line impedance, such as a short circuit, an open circuit or an impedance change point, a portion of the energy will be reflected back to the TDR. Based on the time delay and amplitude of the reflected wave, the fault location and the impedance value at that location can be calculated, thereby achieving detection work.

DETAILED DESCRIPTION

[0019] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] like Figures 1 to 7 As shown, a TDR impedance tester quick-connect connector of the present invention comprises: A quick-install unit 100, used for connecting wires; The clamping structure 200 is mounted on the quick-install unit 100 and is used to clamp on the object to be tested; The quick-install unit 100 includes: The outer cylinder 101 has one end connected to the clamping structure 200 and the other end is configured to be conical; A plurality of clips 102 are distributed in a ring shape on the conical inner side of the outer cylinder 101 around the axis of the outer cylinder 101, and the clips 102 slide on the conical inner wall of the outer cylinder 101 along the generatrix direction of the cone; The slitting knife 103 is located inside the outer cylinder 101 and can move along the axis direction of the outer cylinder 101. The slitting knife 103 is provided with a plurality of cutting edges in the direction of the clamping pieces 102. Each cutting edge is located between two adjacent clamping pieces 102. The slitting knife 103 is electrically connected to the clamping structure 200. The quick-release unit 100 is used to connect the end of the wire installed on the tester, and the clamping structure 200 is used to clamp on the object to be tested, so that the wire and the object to be tested can be quickly connected through the quick-release unit 100 and the clamping structure 200; the outer cylinder 101 is hollow inside, one end of the outer cylinder 101 is conical, the middle part of the outer cylinder 101 is cylindrical, and the other end of the outer cylinder 101 is connected to the clamping structure 200, and multiple clips 102 are located inside the conical part of the outer cylinder 101, and the slitting knife 103 is located inside the cylindrical part of the outer cylinder 101; when connecting the wire, the end of the wire is directly inserted into the conical interior of the outer cylinder 101, and the multiple clips 102 clamp and fix the outer wall of the wire, and the slitting knife 103 cuts the end of the wire through the multiple cutting edges thereon. Since the cutting edge is located between two adjacent clips 102, the cutting edge can smoothly cut the wire skin between the two adjacent clips 102, and the multiple cutting edges cut the wire into multiple petals, so that The wire and the slitting knife 103 can achieve a close contact effect; since the clip 102 moves on the cone of the outer cylinder 101, when the slitting knife 103 cuts the wire and generates a thrust on the wire, the friction between the wire and the clip 102 causes the clip 102 to move on the cone of the outer cylinder 101, and the squeezing force of the clip 102 on the wire increases. Multiple clips 102 can provide a more solid squeezing force for the wire, thereby improving the firmness of the wire connection, and facilitating the smooth cutting of the wire by the cutting edge on the slitting knife 103 to prevent the wire from moving at will. At the same time, the squeezing force of the clip 102 on the wire can make the wire and the slitting knife 103 fit more closely, thereby improving the connection strength; by using the slitting knife 103 to directly cut the wire along the axial direction of the wire, the wire is in direct contact with the slitting knife 103, and the wire can be quickly connected, so that the tester and the object to be tested can be quickly connected, simplifying the connection method and facilitating operation.

[0021] When the multiple clips 102 squeeze the wire, in order to keep the force of the multiple clips 102 on the wire balanced and the multiple clips 102 can keep the axis position of the wire unchanged, the multiple clips 102 need to move synchronously, which can be specifically adopted as follows: Figure 5 The structure shown in FIG. 1 further includes: The synchronizer ring 104 is slidably mounted inside the outer cylinder 101 along the axis direction of the outer cylinder 101. A plurality of connecting rods 105 are rotatably arranged on the synchronizer ring 104. The plurality of connecting rods 105 are rotatably connected to the plurality of clips 102 respectively. A spring 106, one end of which is fixed to the inner wall of the outer cylinder 101, and the other end of which is connected to the synchronizing ring 104; The spring 106 is used to provide elastic thrust for the synchronization ring 104. The synchronization ring 104 can be synchronously connected with the multiple clips 102 through multiple connecting rods 105. When the synchronization ring 104 moves, the multiple clips 102 can move synchronously, so that the multiple clips 102 can provide a balanced force for the wire, and the multiple clips 102 can also provide a stable positioning effect for the wire, so that the wire axis remains fixed; in the natural state, due to the effect of the spring 106, the multiple clips 102 are in a state of being close to each other and closed. At this time, two adjacent clips 102 fit each other. When the wire is inserted into the outer tube 101, the end of the wire will squeeze and push the multiple clips 102 to move, and the two adjacent clips 1 02 are separated from each other, and the spring 106 is elastically deformed. When the space between the multiple clips 102 allows the wire to be inserted, the clip 102 stops moving and the wire is inserted between the multiple clips 102. Due to the characteristics of the tapered part of the outer cylinder 101, when the guide is inserted into the outer cylinder 101, the multiple clips 102 allow the wire to be inserted normally. When the wire is pulled out of the outer cylinder 101, due to the friction between the wire and the clip 102 and the movement trajectory of the clip 102, the clip 102 will produce a large squeezing force on the wire, thereby blocking the pulling-out movement of the wire, thereby achieving an anti-loosening effect and improving the firmness of the connection. The spring 106 can provide auxiliary elastic thrust for the clip 102, so that the clip 102 is always in close contact with the wire.

[0022] like Figure 1 As shown, the number of quick-loading units 100 is set to two, both of which are connected to the clamping structure 200. Two quick-loading units 100 can be used to connect to two wires, so that two testers can share one clamping structure 200, and when one quick-loading unit 100 is damaged, the other quick-loading unit 100 can be used for testing. At the same time, this structural method can also perform wire connection work and increase the wire length, thereby making it easier to carry out testing work.

[0023] Further, such as Figure 1 and Fig. 9 As shown, the clamping structure 200 is composed of two clamping jaws, each of which is composed of a plurality of claw teeth 201, each claw tooth 201 is provided with a conductive sheet 202, the slitting knife 103 is electrically connected to the conductive sheet 202, and the plurality of claw teeth 201 on the two clamping jaws are staggered; The two outer cylinders 101 are rotatably connected to each other, the two outer cylinders 101 are respectively connected to the two clamping claws, and the two outer cylinders 101 are connected via a leaf spring 203; The two quick-loading units 100 and the two clamping claws form a clamp-type structure. When the worker breaks the two quick-loading units 100 apart, the two quick-loading units 100 will drive the two clamping claws to open and separate. At this time, the clamping structure 200 is in an open state, and the leaf spring 203 undergoes elastic deformation. The opened clamping structure 200 is placed on the object to be tested and the two quick-loading units 100 are released. The leaf spring 203 can pull the two quick-loading units 100 closer to each other and make the two clamping claws smoothly clamped on the object to be tested, thereby realizing the rapid connection of the object to be tested; the claw teeth 201 on the clamping claw can play a supporting effect for the conductive sheet 202. When the clamping structure 200 clamps the object to be tested, the clamping connection work is mainly realized with the conductive sheet 202. By using the conductive sheet 202, the clamping structure 200 can achieve a surface contact effect with the object to be tested, thereby improving the conductive effect and the connection firmness; The positions of the multiple claw teeth 201 on the two clamping jaws are staggered, so as to achieve a fully enclosed clamping mode for the object to be measured in the circumferential direction.

[0024] like Fig.10 As shown, the claw 201 is composed of an arc tube 204 and an arc rod 205. The axis of the arc tube 204 coincides with the axis of the arc rod 205. The multiple arc tubes 204 are fixedly connected. The arc rod 205 is inserted into the arc tube 204 by sliding along its arc direction, and the arc tube 204 and the arc rod 205 are connected by a spring. The spring is located on the inner side of the arc tube 204 and is therefore not shown in the accompanying drawings. The spring provides a reset elastic force for the arc rod 205. By utilizing the retractability of the arc tube 204 and the arc rod 205, objects to be tested with different diameters can be conveniently clamped, thereby improving its working application range.

[0025] like Fig.10 As shown, the conductive sheet 202 is composed of a non-elastic sheet 206 located in the middle and two elastic electric sheets 207 located on both sides of the non-elastic sheet 206. One elastic electric sheet 207 is connected to the arc tube 204, and the other elastic electric sheet 207 is connected to the arc rod 205. The non-elastic sheet 206 is used to contact the object to be measured. Since the non-elastic sheet 206 is not elastic, it can contact the object to be measured with different cross-sectional shapes. The elastic electric sheet 207 is used to support the non-elastic sheet 206 and can help the non-elastic sheet 206 to reset. The slitting knife 103 is electrically connected to the non-elastic sheet 206 through the elastic electric sheet 207.

[0026] The non-elastic sheet 206 is made of one of conductive fabrics, conductive polymer composite materials, and conductive paper. Conductive fabrics are made by weaving or knitting conductive fibers together to form conductive fabrics. These fabrics are usually very soft, can bend freely, and will not automatically return to their original shape like a spring. For example, fabrics woven with silver wires, copper wires, or conductive polymer fibers.

[0027] Conductive polymer composites are made by mixing conductive fillers such as carbon nanotubes, graphene, metal powders, etc. into a polymer matrix to prepare conductive composite materials. By adjusting the formula, this composite material can maintain good conductivity while having sufficient flexibility to adapt to the requirements of free bending.

[0028] Conductive paper is made by adding conductive materials such as carbon, metal nanoparticles, etc. to paper. This material is light and flexible, can be bent freely, and has a certain strength.

[0029] In order to achieve the purpose of moving the slitting knife 103, other auxiliary structures need to be provided on the outer cylinder 101, such as Figure 6 to Figure 7 As shown, the quick-install unit 100 also includes: A threaded column 107 connected to the tail of the slitting knife 103; The prism 108 is located inside the outer cylinder 101, with one end fixed inside the outer cylinder 101 and the other end slidingly inserted into the threaded column 107; The threaded sleeve 109 is sleeved on the outer wall of the threaded column 107, and the threaded sleeve 109 and the threaded column 107 are threadedly connected. The threaded sleeve 109 is rotatably mounted on the inner wall of the outer cylinder 101; The prism 108 is used to guide the threaded column 107 so that the threaded column 107 and the slitting knife 103 can only move but not rotate. When the threaded sleeve 109 rotates, since the threaded sleeve 109 is threadedly connected to the threaded column 107, the threaded sleeve 109 will push the threaded column 107 to slide on the prism 108, and the threaded column 107 will push the slitting knife 103 to move, thereby providing power for the slitting knife 103.

[0030] like Figure 8 As shown, the quick-install unit 100 also includes: The rotating ring 110 is rotatably sleeved on the outer wall of the outer cylinder 101, and the inner wall of the rotating ring 110 is provided with teeth; The gear 111 meshes with the teeth on the rotating ring 110. A through hole communicating with the interior of the outer cylinder 101 is provided on the outer wall of the outer cylinder 101. The gear 111 is rotatably installed in the through hole. The outer wall of the threaded sleeve 109 is provided with teeth. The gear 111 meshes with the teeth on the threaded sleeve 109. When adjusting the position of the slitting knife 103, the worker can directly rotate the rotating ring 110, and the rotating ring 110 will drive the threaded sleeve 109 to rotate through the gear 111, thereby realizing power transmission, and this method is more convenient for workers to operate.

[0031] When the quick-install unit 100 is connected to the wire, in order to lock the position of the slitting knife 103, it is necessary to use the following method: Figure 4 and Figure 8In the manner shown, the quick-install unit 100 further includes: The moving ring 112 is sleeved on the outer wall of the rotating ring 110, and the moving ring 112 and the rotating ring 110 rotate synchronously and can slide relative to each other; The clamping ring 113 is connected to the movable ring 112 via a plurality of connecting arms 114. An annular groove is provided on the outer wall of the outer cylinder 101. The clamping ring 113 is located in the annular groove. The connecting arms 114 are connected to the rotating ring 110 via a reset spring 115. Among them, the inner side wall of the annular groove is provided with a plurality of slots 116, and the end face of the snap ring 113 is provided with a plurality of protrusions used in conjunction with the slots 116. In the natural state, due to the action of the reset spring piece 115, the protrusion on the snap ring 113 will be stuck in the slot 116. At this time, the position of the snap ring 113 is locked, and the swivel 110 cannot rotate. When the position of the slitting knife 103 needs to be adjusted, the worker only needs to push the movable ring 112 to move, so that the movable ring 112 drives the snap ring 113 to move through the connecting arm 114, and the protrusion on the snap ring 113 is separated from the slot 116. At this time, the swivel 110 is in an unlocked state, and the movable ring 112 is allowed to slide on the swivel 110. The worker can rotate the movable ring 112 to rotate the swivel 110.

[0032] To improve the fastening effect of the clip 102 on the wire, Figure 5 As shown, the inner wall of the clip 102 is densely covered with reverse teeth 117 , and the reverse teeth 117 can be used to increase the friction strength between the clip 102 and the wire, thereby improving the connection effect and preventing the wire from loosening and falling off on the clip 102 .

[0033] The above are only preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
