Description

Technical Field

[0001] The present application relates to the field of testing technology, and in particular to a self-locking fixing structure and testing equipment. Background Art

[0002] In the testing field, when performing certain tests on test pieces (for example, DC impedance testing), it is necessary to secure the test piece's connectors to prevent them from shaking during the test, potentially affecting the test results. Furthermore, some related technologies involve wiggling the test piece's leads after securing the connectors to test whether and how much the shaking affects the test. This places even higher demands on the securement of the test piece's connectors.

[0003] In the related art, a flip jig or a quick clamp jig with a pre-pressing block is generally used to fix the joints of the test piece. However, on the one hand, it is difficult to fix the joints of the test piece with a smaller size by using a flip jig or a quick clamp jig with a pre-pressing block. The pressing force of the flip jig or the clamping force of the quick clamp jig is too small, which is not conducive to the test; the pressing force of the flip jig or the clamping force of the quick clamp jig is too large, which will damage the joints of the test piece to a certain extent. On the other hand, when fixing the joints of the test piece, it is necessary to manually flip the pre-pressing block or open and close the clamp, which is a cumbersome operation, cannot quickly fix the joints of the test piece, and is not conducive to improving the test efficiency.

[0033] See also Figure 1 The first embodiment of the present application provides a self-locking fixing structure, which is easy to operate and can quickly fix the connector 810 of the test piece, thereby improving the test efficiency.

[0034] See also Figure 1 The self-locking fixing structure includes a base 100 and a moving part 200. The base 100 is provided with a socket 110 for inserting the connector 810 of the test piece. The connector 810 is provided with a first connecting portion 811; the moving part 200 is movable, and the moving part 200 is connected to the base 100 through an elastic part 400. The moving part 200 is provided with a second connecting portion 210. The second connecting portion 210 is used to move toward the direction close to the first connecting portion 811 under the elastic force of the elastic part 400 so as to connect with the first connecting portion 811.

[0035] In the embodiment of the present application, the connector 810 of the test piece can be inserted into the socket 110, and the second connecting portion 210 on the movable member 200 can be moved toward the first connecting portion 811 under the elastic force of the elastic member 400, thereby connecting with the first connecting portion 811 of the connector 810, achieving self-locking, and fixing the connector 810 of the test piece in the socket 110. The self-locking fixing structure in the embodiment of the present application is easy to operate and can quickly fix the connector 810 of the test piece, which is conducive to improving testing efficiency. It also has a better fixing effect and can be applied to smaller test pieces.

[0036] Alternatively, in some embodiments, the movable member 200 is movably connected to the base 100, and the movable member 200 is disposed on one side of the insertion hole 110. A first through slot 120 is defined on a sidewall of the insertion hole 110, and the second connecting portion 210 passes through the first through slot 120 to extend into the insertion hole 110. Optionally, the movable member 200 is disposed on the left side of the insertion hole 110.

[0037] Alternatively, in some embodiments, see Figure 2 The self-locking fixing structure further includes a fastener 300. The movable member 200 is provided with a second through-slot 220. The fastener 300 is disposed in the second through-slot 220. The movable member 200 and the fastener 300 are slidably connected. The fastener 300 is fixedly connected to the base 100. Optionally, the diameter of the fastener 300 is equal to the width of the second through-slot 220.

[0038] From the above content, it can be seen that the moving part 200 is connected to the base 100 through the fastener 300, and the moving part 200 can slide relative to the fastener 300, that is, the moving part 200 can slide relative to the base 100, and the second through groove 220 can play the role of sliding limit.

[0039] Alternatively, the second through slot 220 extends in the horizontal direction, and the moving member 200 is movable in the horizontal direction. Optionally, the fastener 300 is a screw. Of course, the fastener 300 can also be other fasteners such as bolts, pins, etc., and is not specifically limited here.

[0040] Alternatively, in some embodiments, see Figure 3 The first connection part 811 is a groove, and the second connection part 210 is a convex part, and the groove and the convex part are matched and connected.

[0041] For example, when the connector 810 of the test piece is inserted into the socket 110, the connector 810 can push the second connecting part 210 to move the movable part 200 to the left. At this time, the elastic part 400 generates an elastic force. When the first connecting part 811 is aligned with the second connecting part 210, the second connecting part 210 moves to the right under the elastic force of the elastic part 400 until the second connecting part 210 is embedded in the first connecting part 811, achieving self-locking and fixing the connector 810 of the test piece in the socket 110.

[0042] Optionally, in some embodiments, the second connection portion 210 is disposed at one end of the moving member 200 close to the insertion hole 110 , and the second connection portion 210 includes an inclined surface 211 that is inclined toward a side close to the connector 810 along the insertion direction of the connector 810 .

[0043] For example, the connector 810 is inserted into the socket 110 from front to back, that is, the insertion direction of the connector 810 is from front to back, and the inclined surface 211 is inclined from front to back toward the side close to the connector 810. The inclined surface 211 can guide the connector 810 to gradually push the moving member 200 to the left, so that the connector 810 can continue to be inserted into the socket 110.

[0044] Optionally, in some embodiments, the elastic member 400 is a torsion spring, one end of which is fixedly connected to the base 100. Optionally, the lower end of the torsion spring is fixedly connected to the base 100, which is not specifically limited here.

[0045] Of course, the elastic member 400 may also be a spring or other elastic member 400, and no specific limitation is given here. The following description will be made by taking "the elastic member 400 being a torsion spring" as an example.

[0046] Optionally, in some embodiments, participating Figure 1 The self-locking fixing structure also includes a rotating member 500, which is rotatably connected to the base 100. The rotating member 500 includes a column 510, a torsion spring is sleeved outside the column 510, and the rotating member 500 is hinged to the moving member 200. The rotating member 500 is used to drive the moving member 200 to move through its own rotation.

[0047] For example, see Figure 3 When the joint 810 pushes the movable member 200 to move to the left, the rotating member 500 rotates counterclockwise, and the torsion spring generates an elastic force. When the first connecting portion 811 is aligned with the second connecting portion 210, the rotating member 500 rotates clockwise and resets under the elastic force of the torsion spring, thereby driving the movable member 200 to move to the right, so that the second connecting portion 210 is connected to the first connecting portion 811.

[0048] Alternatively, see Figure 2The column 510 is provided with a first through hole 514, the base 100 is provided with a second through hole 130, and the rotation pin 520 is sequentially passed through the second through hole 130 and the first through hole 514, so that the rotating member 500 is rotatably connected to the base 100. Optionally, the column 510 is hollow to form the first through hole 514.

[0049] Optionally, the column 510 includes a first portion 511, a second portion, and a third portion 513 arranged in a vertical direction and connected in sequence. The torsion spring is sleeved outside the second portion. The outer diameters of the first portion 511 and the third portion 513 are larger than the outer diameter of the second portion, which can limit the torsion spring and prevent it from falling out of the column 510. Optionally, the first portion 511, the second portion, and the third portion 513 are arranged in sequence from top to bottom, and the first portion 511, the second portion, and the third portion 513 can be integrally formed, without specific limitation herein.

[0050] Alternatively, see Figure 2 The upper end of the column 510 is provided with a first hinge block 515, which is provided with a slot 5151. The movable member 200 is provided with a cylindrical second hinge block 230, which is hinged in the slot 5151, so that the movable member 200 can move linearly when the rotating member 500 rotates. Optionally, the first hinge block 515 and the first portion 511 are integrally formed.

[0051] Alternatively, in some embodiments, see Figure 2 The rotating member 500 further includes a toggle portion 530, which is fixedly connected to the column 510 and is configured to be toggled to rotate the column 510. Optionally, the toggle portion 530 may be connected to the first portion 511, the third portion 513, or both, without limitation.

[0052] Optionally, in some embodiments, the self-locking fixing structure further includes a dial 600, which is used to dial the dial portion 530, thereby driving the rotating member 500 to rotate. Figure 4 By rotating the rotating member 500 counterclockwise by the dial 600, the movable member 200 can be driven to move leftward, so that the second connecting portion 210 can be moved away from the first connecting portion 811, thereby unlocking the connector 810 of the test piece to be taken out from the socket 110.

[0053] Optionally, the dial 600 is a pin. Figure 2The toggle portion 530 is disposed on the right side of the column 510 and is provided with a third through hole 531 for inserting a pin, thereby preventing the pin from damaging itself or the toggle portion 530 during toggle operation and allowing force to be applied to the toggle portion 530 to toggle the toggle portion 530. Optionally, the toggle portion 530 is made of silicone material, which is beneficial for protecting the toggle member 600.

[0054] Alternatively, in some embodiments, see Figure 5 and Figure 6 The self-locking fixing structure further includes a cover 700, which is connected to the base 100 and a receiving cavity is formed between the cover 700 and the base 100, and the moving member 200 and the rotating member 500 are both received in the receiving cavity. Optionally, the base 100 is connected to the cover 700 by screws.

[0055] Optionally, a guide hole 710 is formed on the cover 700, which is connected to the socket 110, and the connector 810 of the test piece is inserted into the socket 110 through the guide hole 710. Optionally, a fourth through hole 720 is further formed on the cover 700, and the fourth through hole 720 is used to insert a pin to move the toggle portion 530.

[0056] The method of using the self-locking fixing structure in the embodiment of the present application is as follows: Figure 3 , the connector 810 of the test piece is inserted into the socket 110 through the guide hole 710 of the cover body 700, and pushes the movable part 200 to the left through the inclined surface 211, thereby driving the rotating part 500 to rotate counterclockwise. At this time, the torsion spring generates an elastic force. When the first connection part 811 of the connector 810 is aligned with the second connection part 210 of the movable part 200, the rotating part 500 rotates clockwise and resets under the elastic force of the torsion spring, and drives the movable part 200 to move to the right, so that the second connection part 210 is embedded in the first connection part 811, realizing self-locking, and fixing the connector 810 of the test piece in the socket 110.

[0057] When it is necessary to remove the connector 810 from the socket 110, see Figure 4 The ejector pin can be passed through the fourth through hole 720 on the cover body 700 to move the toggle portion 530, driving the rotating member 500 to rotate counterclockwise, thereby driving the moving member 200 to move to the left, and the second connecting portion 210 is separated from the first connecting portion 811 to achieve unlocking, so that the connector 810 can be removed from the socket 110.

[0058] Other structures and operations of the self-locking fixing structure according to the embodiment of the first aspect of the present application are known to ordinary technicians in this field and will not be described in detail here.
