Description

Technical Field

[0001] The present invention relates to the field of testing technology, and in particular to a quick-change fixture, a wiring test fixture and a testing device. Background Art

[0002] In the design of charging products, in order to save internal space and improve the compactness and portability of the product, the flexible cable often needs to be bent. This bending design not only helps to optimize the internal structure of the product, but also reduces the use of materials and reduces costs. Most of the connecting cables of charging products are straight structures or tested before pre-bending. However, the bent flexible cables may be affected by factors such as stress concentration and wear during long-term use, resulting in performance degradation or even failure. Therefore, bending tests are an important means to evaluate the performance stability and service life of the flexible cable in a bent state. The connecting cable of the charging product is improved from a straight structure to a 180° bending structure. The original test fixture is an integrated structure and is no longer suitable for the test of the connecting cable with a bending structure. In order to improve efficiency, the new test fixture adopts a split structural design, and one of the research and development tasks of the split test fixture is to design a fixture for loading the connecting cable to adapt to the bending structure of the connecting cable, facilitate fixture replacement, and reduce the probability of misoperation.

[0037] This embodiment discloses a test device, including a cable test fixture. The cable test fixture includes a quick-change fixture 100. Please refer to Figure 1 and Figure 2 The quick-change fixture 100 includes a bottom plate 110, a shaping plate 120, a pressing member 130 and an anti-fool slide block 140. The bottom plate 110 is provided with a guide hole 111. The bottom plate 110 is provided with a first product placement area 101. The shaping plate 120 is installed on the bottom plate 110. A first product gap 103 is formed between the shaping plate 120 and the first product placement area 101 of the bottom plate 110. The shaping plate 120 is located above the first product placement area 101 and is provided with a second product placement area 102 and a first product gap 103. The first avoidance hole 122 is located at the adjacent side of the second product placement area 102 to form a probe avoidance channel above the first product placement area 101. The pressing member 130 is rotatably mounted on the bottom plate 110 and is located on the first side of the shaping plate 120. Alternatively, the pressing member 130 is lifted and mounted on the bottom plate 110 and is located on the first side of the shaping plate 120. The pressing member 130 can cooperate with the shaping plate 120 to form a first product limiting structure on the first side of the second product placement area 102. Please refer to Figure 3 and Figure 4The anti-foolproof slider 140 is provided with an anti-foolproof convex portion 141, a first crimping portion 142 and a clamping portion 143. The anti-foolproof slider 140 is penetrated and slidably installed in the guide hole 111. The anti-foolproof convex portion 141 and the first crimping portion 142 are both located on the upper side of the bottom plate 110. The clamping portion 143 is located on the lower side of the bottom plate 110 and can cooperate with the bottom plate 110 to form a longitudinal limiting structure. The length direction of the first crimping portion 142 points to the second product placement area 102. The anti-foolproof slider 140 can slide along the guide hole 111 so that the first crimping portion 142 extends into the second product placement area 102, so as to cooperate with the shaping plate 120 to form a second product limiting structure on the second side of the second product placement area 102.

[0038] To facilitate understanding of the inventive concept of the quick-change fixture 100 of this embodiment, the design principle of the quick-change fixture 100 is described below in conjunction with specific application scenarios.

[0039] Please refer to Figure 5 In this embodiment, a connecting cable is used as a target product. The connecting cable has a first part (such as Figure 5 L1) and the second part (as shown Figure 5 As shown by the mark L2, the first part and the second part form a 180° bending structure. Due to the structural improvement of the target product, the original integrated test fixture is not suitable for installing the target product. The new test fixture adopts a split structure, in addition to including the above-mentioned quick-change fixture 100, please refer to Figure 6 The test fixture further includes a base 200 and a probe flip cover 300 .

[0040] Among them, the base 200 is provided with a clamp positioning groove 201 and a limiting locking structure 210, a first avoidance position 203 is provided in the clamp positioning groove 201, and the inner wall of the first avoidance position 203 is provided with a snap-on flange 204; the probe flap 300 has a first end and a second end, the first end of the probe flap 300 is connected to the base 200, and the second end of the probe flap 300 can rotate around the first end relative to the base 200 and is movably connected to the limiting locking structure 210 to cover the clamp positioning groove 201. It should be conceivable that when the probe flap 300 covers the clamp positioning groove 201, the first end and the second end of the probe flap 300 are respectively located on opposite sides of the clamp positioning groove 201, for example, with the length direction of the clamp positioning groove 201 as the first direction (such as Figure 6 The left and right directions indicated in the figure), with the width direction of the fixture positioning groove 201 as the second direction (such as Figure 6 The first end and the second end of the probe flip cover 300 are respectively located on opposite sides of the first direction of the fixture positioning groove 201. Among them, one side edge of the probe flip cover 300 is used as or provided with a foolproof matching portion (such as Figure 6 as indicated by the mark P2).

[0041] Before testing, the target product is installed in the quick-change fixture 100. For example, please refer to Figure 3 , Figure 4 and Figure 5 The first product gap 103 formed between the shaping plate 120 and the first product placement area 101 of the bottom plate 110 is suitable for placing the first part of the target product, and the second product placement area 102 of the shaping plate 120 is suitable for placing the second part of the target product. During the placement process, the first part of the target product is inserted into the first product gap 103 from the front to the back, and the second part of the target product is bypassed from the side of the shaping plate 120 (such as Figure 5 The L3 position marked in the middle is wound at Figure 4 The target product is placed in the second product placement area 102. In order to prevent the target product from rebounding or loosening, the pressing member 130 cooperates with the shaping plate 120 to form a first product limiting structure on the first side of the second product placement area 102, which can limit and fix the target product. At this point, the target product has been loaded in the quick-change fixture 100.

[0042] Next, the quick-change fixture 100 loaded with the target product is placed in the fixture positioning groove 201 of the base 200. The fixture positioning groove 201 can play a role in rough positioning. Figure 4 , Figure 6 and Figure 7 The clamping portion 143 of the anti-foolproof slider 140 can be inserted into the first avoidance position 203 of the base 200. At this time, the anti-foolproof slider 140 is in the first working position. In this working position, the anti-foolproof convex portion 141 of the anti-foolproof slider 140 is located on the movement path of the probe flip cover 300, and the anti-foolproof convex portion 141 of the anti-foolproof slider 140 and the anti-foolproof matching portion (such as Figure 6 or Figure 7 The probe flap 300 is prevented from closing by interference (as indicated by the mark P2), thereby preventing abnormal contact (i.e., the contact position is not the predetermined test point) between the probe 311 on the probe flap 300 and the quick-change fixture 100, thereby protecting the probe 311. Among them, one side edge of the probe flap 300 can be used as an anti-foolproof fitting part, that is, the anti-foolproof slider 140 can interfere with the edge of the probe flap 300 in the first working position; or, one side edge of the probe flap 300 is provided with an anti-foolproof fitting part, for example, the edge of the probe flap 300 is provided with an anti-foolproof protrusion (not shown) used as an anti-foolproof fitting part, and the anti-foolproof slider 140 can interfere with the anti-foolproof protrusion. Next, the anti-foolproof slider 140 is moved to make the anti-foolproof slider 140 move along the guide hole 111, and the anti-foolproof slider 140 switches from the first working position to the second working position (as shown in the figure). Figure 7As shown), at this time, the foolproof slider 140 avoids the foolproof matching part of the probe flip cover 300, and the clamping part 143 of the foolproof slider 140 can be clamped with the clamping flange 204 of the base 200, so as to fix the quick-change fixture 100 on the base 200, and avoid the quick-change fixture 100 from being displaced due to misoperation during the test process, which may cause damage to the probe 311 module or poor test. In addition, the first crimping part 142 of the foolproof slider 140 can also cooperate with the shaping plate 120 to form a second product limiting structure on the second side of the second product placement area 102, so as to limit and shape the target product. Next, the probe flip cover 300 is covered on the fixture positioning groove 201, and part of the probe 311 on the probe flip cover 300 passes through the first avoidance hole 122 of the shaping plate 120 to be electrically connected to the test point of the first part of the target product. Of course, part of the probe 311 on the probe flip cover 300 is electrically connected to the test point of the second part of the target product. It is worth mentioning that the anti-mistake slider 140 can cooperate with the probe flip cover 300 for anti-mistake, and can also cooperate with the snap-on flange 204 of the base 200 to achieve the locking of the quick-change fixture 100, and can also cooperate with the second side of the shaping plate 120 to press the target product. It has a simple structure but diverse functions, which is conducive to achieving a miniaturized design.

[0043] As a result, a first product gap 103 is formed between the first product placement area 101 of the shaping plate 120 and the bottom plate 110, which can be adapted to the bending structure of the target product. The clamping piece 130 cooperates with the shaping plate 120 to form a first product limiting structure on the first side of the second product placement area 102. The anti-foolproof protrusion 141 of the anti-foolproof slider 140 can play an anti-foolproof effect during use and reduce the probability of misoperation. The anti-foolproof slider 140 can slide along the guide hole 111. The first crimping portion 142 of the anti-foolproof slider 140 can cooperate with the shaping plate 120 to form a second product limiting structure on the second side of the second product placement area 102 to fix the target product. The clamping portion 143 of the anti-foolproof slider 140 can cooperate with the bottom plate 110 to form a longitudinal limiting structure, so as to facilitate the fixing and disassembly of the quick-change fixture 100 during use, which is beneficial to improving work efficiency.

[0044] Please refer to Figure 1 A second elastic pressing member 150 is disposed on the bottom plate 110 and located on the first side of the shaping plate 120. The second elastic pressing member 150 can cooperate with the side wall of the shaping plate 120 to form a third product limiting structure. When the target product is placed on the shaping plate 120 for preliminary shaping, the second elastic pressing member 150 can press the bending position of the target product and cooperate with the shaping plate 120 to laterally fix the bending position of the target product from the side. The second elastic pressing member 150 is a passive pressing structure, which does not require active human operation and is easy to use.

[0045] Please refer to Figure 3 and Figure 4 The second elastic pressing member 150 includes a second assembly structure 151, a second pressing block 152 and a fourth elastic member 153. The second assembly structure 151 is provided with a second guide cavity (such as Figure 4 As shown by mark Z1 in the figure, the second pressing block 152 is movably installed in the second guide cavity and extends out of the second assembly structure 151 and points to the side wall of the shaping plate 120. The fourth elastic member 153 is installed in the second assembly structure 151 and abuts against the second pressing block 152. Among them, the second assembly structure 151 can be a shell installed on the base plate 110, or the second assembly structure 151 can be a structure processed on the base plate 110. When the target product is preliminarily shaped by the shaping plate 120, the bending position of the target product abuts against the second pressing block 152, so that the second pressing block 152 compresses the fourth elastic member 153. The fourth elastic member 153 provides continuous elastic force for the second pressing block 152, so that the second pressing block 152 maintains the bending position of the target product (such as Figure 5 The fourth elastic member 153 is a spring.

[0046] Please continue to refer to Figure 3 and Figure 4 The second elastic pressing member 150 is arranged on the movement path of the pressing member 130 so as to provide support for the pressing member 130. The pressing member 130 can abut against the second elastic pressing member 150 to cooperate with the second side of the second product placement area 102 of the shaping plate 120 to form a second product limiting structure with a preset limiting space. After the target product is placed on the shaping plate 120 for preliminary shaping, the pressing member 130 is manually rotated so that the pressing member 130 presses the target product from above. Since the second elastic pressing member 150 is located on the movement path of the pressing member 130, when the pressing member 130 rotates to a predetermined angle position, the pressing member 130 abuts against the second elastic pressing member 150 so that the pressing member 130 cannot rotate further, thereby preventing the manual rotation of the pressing member 130 from being too strong and causing the target workpiece to be subjected to excessive pressure, thereby achieving the effect of protecting the target product. In this way, the second elastic pressing member 150 can set the limiting space between the pressing member 130 and the shaping plate 120 to a preset width to meet the pressing requirements of the target product and prevent the target product from being damaged due to excessive pressing force. Figure 6 and Figure 7A hand-grip position 205 is provided on the base 200 and on one side of the fixture positioning groove 201. The positions of the clamping piece 130 and the second elastic pressing piece 150 are adapted to the hand-grip position 205 of the base 200. When the quick-change fixture 100 needs to be installed on the base 200, during the process of the operator manually taking the quick-change fixture 100, the operator's thumb presses on the clamping piece 130, and the operator's other fingers can clamp from the bottom of the base plate 110 of the quick-change fixture 100. In this way, during the process of taking the quick-change fixture 100, it can be ensured that the clamping piece 130 always keeps pressing on the target product to prevent the target product from being deformed during installation. In this process, the second elastic pressing piece 150 provides reverse support force for the clamping piece 130 to prevent the clamping piece 130 from applying excessive pressure on the target product and damaging the target product. When the quick-change fixture 100 is placed in the fixture positioning groove 201 of the base 200 , the hand-locking position 205 on the base 200 can avoid the operator's fingers, so as to facilitate the placement of the quick-change fixture 100 .

[0047] Please refer to Figure 3 and Figure 4 The clamping member 130 is provided with a first connection part 131, a second connection part 132 and a second crimping part 133. The first connection part 131 is rotatably connected to the bottom plate 110. The first end of the second connection part 132 is connected to the first connection part 131, and the second end of the second connection part 132 is connected to the second crimping part 133. The length direction of the second crimping part 133 is perpendicular to the length direction of the second connection part 132. The second crimping part 133 cooperates with the shaping plate 120 to form a first product limiting structure. The length direction transformation between the first connection part 131 and the second crimping part 133 can be achieved through the second connection part 132, and the installation position of the second elastic top pressing member 150 can be avoided to save installation space. At least one of the second connection part 132 and the second crimping part 133 is magnetically connected to the second elastic top pressing member 150 to fix the second crimping part 133 so that the second crimping part 133 can press the target product. For example, at least one of the second connecting portion 132 and the second crimping portion 133 is provided with a first magnetic member, and a second magnetic member is provided on the second assembly structure 151 of the second elastic pressing member 150, and the first magnetic member and the second magnetic member can be adsorbed and connected to each other. Among them, both the first magnetic member and the second magnetic member are magnets, or one of the first magnetic member and the second magnetic member is a magnet, and the other of the first magnetic member and the second magnetic member is a magnetic conductive material, such as iron. In other application examples (this example is not shown), the first connecting portion 131 is vertically mounted on the base plate 110, and the second connecting portion 132 is slidably connected to the first connecting portion 131, so as to realize the lifting and lowering movement of the second crimping portion 133, and then realize the lifting and lowering connection between the pressing member 130 and the base plate 110.

[0048] Please refer to Figure 2 and Figure 4 A guide flange 112 is provided on the bottom plate 110 and in the guide hole 111. A bottom cover 113 is installed in the guide hole 111. The bottom cover 113 and the guide flange 112 cooperate to form a guide slot 114. The anti-fool slide block 140 is provided with a sliding connection portion 144 (refer to Figure 8 ), the sliding connection part 144 is movably installed in the guide groove 114, so that the anti-foolproof slider 140 can slide along the guide hole 111, thereby switching between the first working position and the second working position.

[0049] For some application examples, see Figure 4 and Figure 8 , a third magnetic member 145 is disposed on the anti-stupid slider 140, a bottom cover 113 is installed in the guide hole 111, a fourth magnetic member is disposed on the bottom cover 113 or the side wall of the bottom cover 113 is used as the fourth magnetic member, and the anti-stupid slider 140 and the bottom cover 113 are adsorbed and connected by the third magnetic member 145 and the fourth magnetic member. For example, the third magnetic member 145 is disposed on the anti-stupid slider 140 and located on one side or two opposite sides of the sliding direction, and the number and position of the fourth magnetic member are respectively adapted to the number and position of the third magnetic member 145. According to the different arrangement positions of the third magnetic member 145 and the fourth magnetic member, when the anti-study slider 140 is in the first working position, the anti-study slider 140 and the bottom cover 113 can be adsorbed by the third magnetic member 145 and the fourth magnetic member, or when the anti-study slider 140 is switched to the second working position, the anti-study slider 140 and the bottom cover 113 can be adsorbed by the third magnetic member 145 and the fourth magnetic member, so that the anti-study slider 140 is switched to the right position. The fourth magnetic member can be arranged on the bottom cover 113, or the third magnetic member 145 is a magnet, and the side wall of the bottom cover 113 is made of a magnetic conductive material, so as to be used as the fourth magnetic member.

[0050] Alternatively, in some other application examples (this example is not shown in the figure), a third magnetic component 145 is provided on the anti-stupidity slider 140, and a fourth magnetic component is provided on the inner wall of the guide hole 111, and the anti-stupidity slider 140 and the inner wall of the guide hole 111 are adsorbed and connected by the third magnetic component 145 and the fourth magnetic component. In this application example, the working principle of the third magnetic component 145 and the fourth magnetic component is the same as the working principle of the above application example, except that the fourth magnetic component can be directly installed on the inner wall of the guide hole 111. Among them, the third magnetic component 145 and the fourth magnetic component are both magnets, or one of the third magnetic component 145 and the fourth magnetic component is a magnet, and the other of the third magnetic component 145 and the fourth magnetic component is a magnetic conductive material, such as iron.
