Description

Technical Field

[0001] The utility model relates to the technical field of connector detection, in particular to a clamping device for connector plugging and pulling force detection. Background Art

[0002] Connector plugging and unplugging force detection is an important test item in the connector production process. It is used to evaluate the force applied to the connector during plugging and unplugging operations to ensure the reliability and durability of the connector. It is often tested using a plugging and unplugging force tester. A standard interface is usually installed on the plugging and unplugging force tester, and the connector sample to be tested is then fixed on the clamping end of the plugging and unplugging force tester. When the plugging and unplugging force tester is started, the clamping end can be driven to perform plugging and unplugging operations. At this time, the force sensor on the plugging and unplugging force tester monitors the plugging and unplugging force in real time, and the plugging and unplugging force curve can be recorded. The plugging and unplugging force data is then transmitted to the data acquisition system for data analysis. The peak value, average value, and fluctuation of the plugging and unplugging force can be analyzed to evaluate the plugging and unplugging performance and stability of the connector. Based on the plugging and unplugging force test results, evaluate whether the quality and performance of the connector meet the design requirements.

[0003] In the prior art, the clamping end on the plug-in force tester usually uses screws or clamps to fix the connector sample. When in use, it is inconvenient to assemble and disassemble, which affects the detection efficiency, and the fixing effect is poor. During the test, the connector sample is prone to movement, resulting in inaccurate test data and prone to misjudgment, affecting the detection quality. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that the clamping effect is poor and the connector sample is prone to relative sliding, and proposes a clamping device for connector plugging and pulling force detection.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A clamping device for connector plugging and unplugging force detection comprises a fixed seat, a connecting seat detachably connected to an plugging and unplugging force tester is fixedly arranged on the top of the fixed seat, and at least one group of clamping plates are slidably arranged on the fixed seat, wherein a clamping groove is provided on the clamping plate, a clamping pad is fixedly arranged in the clamping groove, a groove is provided on the clamping end face of the clamping pad, and a driving part for driving the clamping plate to slide is provided on the fixed seat.

[0007] In order to improve the fixing effect of the connector sample, preferably, the end surface of the side wall of the clamping groove is inclined, and the inclination angle ranges from 1 degree to 6 degrees.

[0008] In order to ensure reliable sliding of the clamping plate, preferably, a slide groove is provided in the fixing seat, the top of the clamping plate is slidably arranged in the slide groove, and two groups of the clamping plates are symmetrically arranged.

[0009] In order to facilitate driving the two groups of clamping plates for clamping, the driving part further includes a bidirectional screw rotatably arranged in the slide groove, wherein the two groups of clamping plates are respectively threadedly connected to the two ends of the bidirectional screw, and a knob is fixedly arranged on one end of the bidirectional screw extending out of the slide groove.

[0010] Preferably, a protrusion is fixedly provided on the clamping end surface of the clamping pad, and the protrusion is in a wavy line shape.

[0011] Preferably, a plug-in slot is provided on the connection seat, the cross-sectional shape of the plug-in slot is polygonal, and a pin hole penetrating the plug-in slot is provided on the side wall of the connection seat.

[0012] Compared with the prior art, the utility model provides a clamping device for connector plugging and pulling force detection, which has the following beneficial effects:

[0013] 1. The clamping device for connector plugging and unplugging force detection has a clamping groove on the clamping plate, a clamping pad fixedly arranged on the side wall of the clamping groove, and a groove on the clamping pad. When clamping, negative pressure is generated in the spherical hole, so that the mouth of the cylindrical hole is adsorbed on the end face of the connector sample, which can increase the fixing strength of the connector sample and prevent the connector sample from sliding relative to the clamping plate during plugging and unplugging, resulting in inaccurate test data and affecting the test quality.

[0014] 2. The clamping device for connector plugging and unplugging force detection has the side walls of the clamping groove tilted so that when clamping, the clamping pad at the clamping groove mouth is first clamped with the connector sample. At this time, a force is generated to make the connector sample slide into the clamping groove, thereby increasing the bite effect on the connector sample and further improving the fixing strength.

[0015] The parts not involved in the device are the same as the prior art or can be implemented by using the prior art. The utility model has a clamping pad fixedly arranged on the side wall of the clamping groove, and a groove is opened on the clamping pad. When clamping, negative pressure is generated in the spherical hole, so that the mouth of the cylindrical hole is adsorbed on the end face of the connector sample, which can increase the fixing strength of the connector sample and prevent the connector sample from sliding relative to the clamping plate during plugging and unplugging, resulting in inaccurate test data and affecting the test quality.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] Example:

[0025] Reference Figure 1-Figure 5A clamping device for testing the plugging and unplugging force of a connector includes a fixing seat 1, on the top of which is fixedly provided a connecting seat 3 which is detachably connected to a plugging and unplugging force tester. When in use, the fixing seat 1 is fixed to the test rod of the plugging and unplugging force tester through the connecting seat 3. It also includes at least one group of clamping plates 2. Here, we prefer two groups of clamping plates 2, and the two groups are symmetrically arranged and slidably arranged on the fixing seat 1 respectively, wherein clamping grooves 201 are provided on the adjacent end faces of the two groups of clamping plates 2, and then a clamping pad 4 is fixedly provided on the inner side wall of the clamping groove 201. The material of the clamping pad 4 is rubber, silicone or polyurethane, preferably polyurethane, and a groove 401 is provided on the clamping end face of the clamping pad 4. There are multiple groups of grooves 401, preferably fifty-five groups, and the grooves 401 are composed of cylindrical holes and spherical holes. When the connector sample is placed between the two groups, The two groups of clamping pads 4 are placed between each other, and then the two groups of clamping pads 4 approach the connector sample to clamp it. When the clamping pads 4 continue to be squeezed by the clamping plate 2, the clamping end face of the clamping pad 4 can fit with the end face of the connector sample, and a part of the gas in the spherical hole will be squeezed out in this process. When the clamping plate 2 stops moving, a certain negative pressure will be generated in the spherical hole, so that the end face of the cylindrical hole is adsorbed on the end face of the connector sample, which can increase the fixing strength of the connector sample and prevent the connector sample from sliding relative to the clamping plate 2 during plugging and unplugging, resulting in inaccurate test data and affecting the test quality. In addition, a driving part for driving the clamping plate 2 to slide is provided on the fixing seat 1. When in use, the clamping plate 2 can be driven to slide through the driving part to achieve rapid clamping and loosening of the connector sample, which helps to improve the detection efficiency.

[0026] When in use, a clamping groove 201 is provided on the clamping plate 2, a clamping pad 4 is fixedly arranged on the side wall of the clamping groove 201, and a groove 401 is provided on the clamping pad 4. When clamping, negative pressure is generated in the spherical hole so that the mouth of the cylindrical hole is adsorbed on the end face of the connector sample, thereby increasing the fixing strength of the connector sample and preventing the connector sample from sliding relative to the clamping plate 2 during plugging and unplugging, thereby preventing inaccurate test data and affecting the test quality. By tilting the side wall of the clamping groove 201, when clamping, the clamping pad 4 at the mouth of the clamping groove 201 is first clamped with the connector sample, and at this time, a force is generated to make the connector sample slide into the clamping groove 201, thereby increasing the bite effect on the connector sample and further improving the fixing strength.

[0027] Reference Figure 4 and Figure 5Here, we design the side wall end face of the clamping groove 201 to be inclined, and the inclination angle ranges from 1 degree to 6 degrees, preferably 2 degrees. That is to say, the distance between the mouths of the two groups of clamping grooves 201 is smaller than the distance between the tops of the clamping grooves 201. During the clamping process, there is a certain thrust, which makes the connector sample tend to slide toward the top of the clamping groove 201, which helps to improve the clamping effect.

[0028] Reference Figure 1-Figure 4 A slide groove 101 is provided in the fixing seat 1, and the top of the clamping plate 2 is slidably arranged in the slide groove 101, which can ensure that the clamping plate 2 slides reliably and prevents it from flipping over and affecting normal use. In addition, two groups of clamping plates 2 are symmetrically arranged. When there is only one group of clamping plates 2, the connector sample is placed in the slide groove 101, and then the clamping plate 2 is driven to approach the connector sample to clamp it. Here, it is preferably symmetrically arranged with two groups. When in use, the two groups of clamping plates 2 are driven to slide by the driving part, so that the two groups of clamping plates 2 are close to or away from each other, so as to clamp or release the connector sample.

[0029] Reference Figure 4 The driving part adopts a cylinder, a hydraulic cylinder or an electric telescopic cylinder to drive the two groups of clamping plates 2 to clamp or release. Here, we design the driving part as: rotating the bidirectional screw 5 arranged in the slide groove 101, wherein the ends of the two groups of clamping plates 2 in the slide groove 101 are respectively threadedly connected with the two ends of the bidirectional screw 5, and the spiral line of the bidirectional screw 5 has self-locking property, and the bidirectional screw 5 can be driven to rotate by a motor. Here, we preferably fix a knob 501 on the end of the bidirectional screw 5 extending out of the slide groove 101, and drive the bidirectional screw 5 to rotate by the knob 501, which is easy to operate. When in use, the bidirectional screw 5 is driven to rotate by the knob 501, which can drive the two groups of clamping plates 2 to move closer or farther from each other, thereby clamping or releasing the connector sample. The operation is simple, easy to use, and can improve the detection efficiency.

[0030] Reference Figure 1 and Figure 2 A protrusion 402 is fixedly provided on the clamping end face of the clamping pad 4. On the clamping end face, the protrusion 402 is located at the top and bottom of the groove 401, and the protrusion 402 is in a wavy line shape. When in use, by fixing the protrusion 402 on the clamping pad 4, the anti-slip effect can be improved, the surface area in contact with the end face of the connector sample is increased, and the possibility of sliding of the connector sample is reduced.

[0031] Reference Figure 1 , Figure 2 and Figure 4A plug-in slot 301 is provided on the connecting seat 3, and the cross-sectional shape of the plug-in slot 301 is a polygon, which can be a rectangle, a pentagon or a hexagon, preferably a rectangle, corresponding to the head shape of the test rod of the plug-in force tester, and a pin hole 302 penetrating the plug-in slot 301 is provided on the side wall of the connecting seat 3, and a pin hole 302 is provided correspondingly on the head of the test rod. When in use, the test rod is inserted into the plug-in slot 301, and then the pin rod is passed through the pin hole 302, and then the hand-tightening nut is threadedly connected to the pin rod to realize the fixed connection between the fixing seat 1 and the test rod. The fixing is convenient to assemble and disassemble, reliable, and convenient to replace different fixing seats 1, thereby improving the scope of use.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
