Description

Technical Field

[0001] The present invention relates to the field of cable connector testing, and particularly provides a clamping structure and a testing device for testing the pull-off force of a cable connector. Background Art

[0002] Cables are the main transmission bodies of energy and signals in new energy electric aircraft. Each cable is connected to other electrical appliances through connectors welded / crimped at its end, thereby realizing the construction of the entire energy and signal transmission network of the new energy electric aircraft. Therefore, the quality of the connection between the cable and the connector directly affects the safety of the aircraft during flight. Therefore, it is necessary to test the pull-off force to judge the connection quality between the cable and the connector.

[0003] The existing cable connector pull-off force test is usually carried out by clamping the connector itself for tensile testing. This method is prone to damage the connector and is not conducive to the recycling and reuse of the connector. There is also a testing method in which the cable is passed through a hole fixture with a fixed size, and the connector is left at the other end of the hole and then tensile testing is carried out. Usually, the clamping device used in this method is relatively cumbersome to assemble, and the clamping device can only clamp cables of a single specification and cannot cover cables of different specifications. If the pull-off force test of cables of different specifications is to be realized, multiple clamping devices corresponding to various specifications one by one need to be prepared, which will cause the occupation and waste of resources.

[0004] Therefore, it has become an urgent problem for people to provide a clamping structure and a testing device for testing the pull-off force of a cable connector that are easy to assemble and can meet cables of different specifications. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a clamping structure for testing the pull-off force of a cable connector to solve the problems that the existing clamping device is prone to damage the connector, is not easy to assemble, and cannot adapt to cables of multiple specifications.

[0006] On the one hand, the present invention provides a clamping structure for testing the pull-off force of a cable connector, including: a clamping body and an assembly module. Among them, the clamping body is an openable and closable structure, and when closed, it can form an accommodating space. After being assembled, the assembly module can cooperate with the clamping body, be fixedly blocked at the opening end of the accommodating space, and a cable through hole is formed in the middle, which is used to prevent the cable connector staying in the accommodating space from detaching from the clamping structure for testing the pull-off force of the cable connector during testing. The assembly module includes multiple groups of assembly module units with gradually increasing sizes. Each group of assembly module units includes two split docking structures with the same structure that can be docked in the middle to form a placement hole, and the assembly module units can be sequentially fitted and sleeved through the placement hole.

[0007] Preferably, the clamping body includes a connecting pipe and a clamping head. The clamping head is funnel-shaped, and its small end is fixedly connected to the connecting pipe.

[0008] More preferably, a fixing ring is fixedly connected to the large end of the clamping head, and the assembling module can be snap-fitted with the fixing ring.

[0010] More preferably, one end of the outer circles of the two parts forming the fixing ring is hinged, and the other end is connected by a buckle. The free ends of the two parts forming the connecting pipe are locked by a locking mechanism.

[0011] More preferably, the longitudinal section of the placement hole formed in the middle of the assembling module unit is triangular, and a convex rib with a triangular longitudinal section is arranged on the outside of the assembling module. Adjacent assembling module units are sleeved with each other through the placement hole and the convex rib.

[0012] More preferably, the assembling module further includes an assembling module central unit that can be sleeved inside the innermost assembling module unit. When the assembling module central unit and the assembling module units are sleeved in sequence, a complete plane is formed on the upper top surface of the assembling module.

[0013] The present invention also provides a cable connector pull-off force testing device, including: the above-mentioned clamping structure for cable connector pull-off force testing and a testing machine. Among them, the testing machine includes a connecting base, and the clamping body of the clamping structure for cable connector pull-off force testing is detachably connected to the connecting base.

[0014] Preferably, the connecting base includes a bottom plate and a slot vertically connected to the bottom plate. The clamping body includes a connecting pipe composed of two symmetrically left and right parts. After the connecting pipes are butted, they can be inserted into the slot in a matching manner and locked by a locking mechanism.

[0015] More preferably, positioning jacks are correspondingly arranged on the slots of the connecting pipe. The locking mechanism includes a positioning pin and a safety pin. The positioning pin passes through the connecting pipe and the slot in a matching manner and is locked by the safety pin.

[0016] The clamping structure for cable connector pull-off force testing provided by the present invention can adjust the assembling module according to the specifications of the cable to make it adapt to cables of different specifications. At the same time, rapid assembly can be achieved.

[0017] The clamping structure for cable connector pull-off force testing and the testing device provided by the present invention have a reasonable structure and are convenient to assemble, and can meet the requirements of cables of various specifications. Description of the Drawings

[0020] Figure 2 This is a usage state diagram of the clamping structure for cable connector pull-off force testing provided by the present invention;

[0022] The present invention will be further explained below in conjunction with specific implementation schemes, but the present invention is not limited thereto.

[0023] In order to solve the problems that the clamping device for cable connector pull-off force testing in the past was prone to damage the connector, inconvenient to assemble, and unable to adapt to various specifications of cables, as Figures 1 to 3 shown, the present invention provides a clamping structure for cable connector pull-off force testing, including: a clamping body 1 and an assembly module. Among them, the clamping body 1 is an openable and closable structure, and when closed, it can form an accommodation space. After being assembled, the assembly module can cooperate with the clamping body 1, fixedly block the opening end of the accommodation space, and form a cable through-hole in the middle, so as to prevent the cable connector 3 staying in the accommodation space from detaching from the clamping structure for cable connector pull-off force testing during testing. The assembly module includes multiple groups of assembly module units 21 with gradually increasing sizes. Each group of assembly module units 21 includes two split docking structures 211 with the same structure that can be docked in the middle to form a placement hole. The assembly module units 21 can be sequentially fitted and sleeved through the placement holes.

[0024] The usage method of the clamping structure for cable connector pull-off force testing is as follows: When pull-off force testing is required, open the clamping body. At this time, the split docking structures of the assembly module units are separated from each other. Then, determine the assembly module unit that matches the cable 6 according to the specification size of the cable 6, that is: make the cable through-hole formed after the docking of the assembly module unit match the specification size of the cable 6. Next, sleeve from the outermost circle of the assembly module inward in sequence until the determined assembly module unit is reached as the innermost circle assembly module unit. Then, place the cable connector into the accommodation space and close the clamping body. At this time, the assembly module fixedly blocks the opening end of the accommodation space, retains the cable connector in the accommodation space, and the cable 6 is matched with the cable through-hole of the innermost circle assembly module. Thus, the clamping of the cable connector is completed.

[0025] After the cable connectors at both ends of the cable are correspondingly clamped by the two clamping structures, fix the two ends of the clamping structure on the testing machine, and then conduct the pull-off force test of the cable connector according to the requirements of the corresponding standard specifications.

[0026] As an improvement of the technical solution, as Figures 1 to 3 shown, the clamping body 1 includes a connecting pipe 11 and a clamping head 12. The clamping head 12 is funnel-shaped, and the small end is fixedly connected to the connecting pipe 11. The assembly module can be fixedly sealed at the open end of the funnel-shaped accommodating space, and a cable connector accommodating area is formed in the middle.

[0027] As an improvement of the technical solution, as Figures 1 to 3 shown, a fixing ring 13 is fixedly connected to the large end of the clamping head 12. The assembly module can be snap-fitted with the fixing ring 13. The snap-fitting structure can be various, as long as it can limit the closed assembly module within the closed fixing ring.

[0028] As an improvement of the technical solution, as Figures 1 to 3 shown, the connecting pipe 11, the clamping head 12 and the fixing ring 13 all include two symmetric parts on the left and right.

[0029] As an improvement of the technical solution, as Figures 1 to 3 shown, one end of the outer ring of the two parts forming the fixing ring 13 is hinged by a hinge 7, and the other end is connected by a buckle 8. The free ends of the two parts forming the connecting pipe 11 are locked by a locking mechanism.

[0030] As an improvement of the technical solution, as Figure 1 , Figure 3 shown, the longitudinal section of the placement hole formed in the middle of the assembly module unit 21 is triangular. A convex rib with a triangular longitudinal section is arranged on the outside of the assembly module 1. Adjacent assembly module units 21 are sleeved with each other through the placement hole and the convex rib. Similarly, the fixing ring and the outermost assembly module unit can also be snap-fitted with this structure.

[0031] As an improvement of the technical solution, as Figure 1 shown, the assembly module further includes an assembly module center unit 22 that can be sleeved inside the innermost assembly module unit 21. When the assembly module center unit 22 and the assembly module unit 21 are sequentially sleeved, a complete plane is formed on the upper top surface of the assembly module, so that this clamping structure can also act as a test fixture for plane compression.

[0032] As Figure 2 , Figure 3As shown in the figure, the present invention further provides a cable connector pull-off force test device, including: the above-mentioned clamping structure for cable connector pull-off force test and a testing machine. Among them, the testing machine includes a connecting base 4, and the clamping body 1 of the clamping structure for cable connector pull-off force test is detachably connected to the connecting base 4.

[0033] As an improvement of the technical solution, as Figure 2 , Figure 3 shown, the connecting base 4 includes a bottom plate 41 and a slot 42 vertically connected to the bottom plate 41. The clamping body 1 includes a connecting pipe 11 composed of two symmetric left and right parts. After the connecting pipes 11 are butted, they can be inserted into the slot 42 in cooperation and locked by a locking mechanism.

[0034] As an improvement of the technical solution, as Figure 2 , Figure 3 shown, positioning jacks are correspondingly arranged on the slot 42 of the connecting pipe 11. The locking mechanism includes a positioning pin 51 and a safety pin 52. The positioning pin 51 is inserted through the connecting pipe 11 and the slot 42 in cooperation and locked by the safety pin 52.
