[0041] In order to solve the technical problem that the detection mechanism of the connector in the prior art lacks the function of not swinging the wire harness of the connector during testing, thereby making it difficult to accurately test the conductivity of the connector, embodiments of the present application provide an electrical testing device for a connector.

[0042] The specific structure of the electrical testing device for a connector provided by the embodiments of the present application will be described in detail below. According to the drawings shown in the embodiments of the present application, the specific structure of the electrical testing device for a connector includes a workbench, a first pressing assembly 2, an electrical testing assembly 3, and a swinging assembly 4. Figures 1-4 ​

[0043] The workbench is provided with a jig 1, and the jig 1 is assembled with a connector 6 to be tested.

[0044] Specifically, the connector 6 to be tested is accurately positioned by forming the first positioning cavity and the second positioning cavity for assembling the connector body and the wire harness respectively, so that the position of the connector 6 to be tested in the subsequent detection process is ensured to be accurate, and the connector 6 to be tested is prevented from shaking during the detection process.

[0045] According to Figure 1 , Figure 2 and Figure 4 , specifically, the jig 1 comprises a base 14, and a first positioning jig 11 and a second positioning jig 12 arranged on the base 14, the first positioning cavity is formed in the first positioning jig 11, and the second positioning cavity is formed in the second positioning jig 12.

[0046] Specifically, the male head of the connector 6 to be tested and the wire harness of the connector 6 to be tested are assembled in the first positioning cavity of the first positioning jig 11 and the second positioning cavity of the second positioning jig 12 respectively; since the first positioning cavity is matched with the shape and size of the connector male head, when the male head of the connector 6 to be tested is assembled in the first positioning cavity, the correct positioning of the connector 6 to be tested is ensured, the connector 6 to be tested is prevented from shaking left and right, and the pins of the male head of the connector 6 to be tested are ensured to be oriented relative to the electrical test probe 33. Since the width of the second positioning cavity is matched with the outer diameter of the wire harness of the connector 6 to be tested, when the wire harness is placed in the second positioning cavity, the wire harness of the connector 6 to be tested is supported, and the wire harness is prevented from deviating during the test.

[0047] According to Figure 1 and Figure 2 , in a further embodiment, the second positioning jig 12 is provided with a wire clamping block 13, the wire clamping block 13 is recessed with a positioning groove, and the tail ends of the plurality of wire cores of the connector 6 to be tested are assembled in the positioning groove.

[0048] Specifically, the tail ends of the plurality of wire cores are supported by the positioning groove of the wire clamping block 13, and the tail ends of the two wire cores close to the groove walls of the positioning groove are respectively in contact with the two side groove walls of the positioning groove, so as to prevent the tail ends of the wire cores from shaking violently during the test, so as to ensure that the tail ends of the wire cores are fixedly clamped and positioned.

[0049] It should be noted that the first pressing assembly 2, the electrical test assembly 3 and the swinging assembly 4 of the embodiment of the utility model are arranged on the workbench, and are used to support the first pressing assembly 2, the electrical test assembly 3 and the swinging assembly 4.

[0050] According to Figure 1As shown, the first pressing assembly 2 comprises a first driver 21, a lifting seat 22, a metal block 23 and a first pressing part 24; the first pressing part 24 and the metal block 23 are both arranged on the lifting seat 22, and the power output shaft of the first driver 21 is drivingly connected with the lifting seat 22.

[0051] Specifically, in order to prevent the to-be-tested connector 6 from shaking and easily falling off during detection, the lifting seat 22 is pushed to move downward by the power output shaft of the first driver 21 until the bottom surface of the first pressing part 24 abuts against the male head of the to-be-tested connector 6, so as to press the male head of the connector, and the male head of the connector is clamped under the action of the first pressing part 24 and the jig 1, thereby ensuring that the to-be-tested connector 6 can be stably positioned at a specified position and avoiding the to-be-tested connector 6 from shaking during detection; after the detection of the to-be-tested connector 6 is completed, the power output shaft of the first driver 21 is reset to move the first pressing block upward until the first pressing block is away from the male head of the to-be-tested connector 6, and then the to-be-tested connector 6 can be taken out of the jig 1 or the jig 1 assembled with the to-be-tested connector 6 can be output to other testing procedures.

[0052] According to Figure 2 As shown, the electrical testing assembly 3 comprises a second driver 31, an electrical testing part 32 and a plurality of electrical testing probes 33; each electrical testing probe 33 is arranged on the side of the electrical testing part 32 close to the jig 1, and the power output shaft of the second driver 31 is drivingly connected with the electrical testing part 32.

[0053] Specifically, in the detection of the to-be-tested connector 6, when the first pressing part 24 presses the to-be-tested connector 6, the electrical testing part 32 is pushed to move along the direction of the to-be-tested connector 6 by the power output shaft of the second driver 31 until each electrical testing probe arranged on the electrical testing part 32 is respectively inserted into each pin of the male head of the to-be-tested connector 6, and then each electrical testing probe outputs test current, voltage and signal to each pin, thereby detecting the conductivity of each to-be-tested connector 6; after the detection of the to-be-tested connector 6 is completed, each electrical testing probe is separated from each pin by the reset movement of the power output shaft of the second driver 31.

[0054] It should be noted that when the lifting seat 22 is driven by the first driver 21 to move downward until the male head of the to-be-tested connector 6 is pressed by the first pressing part 24, the metal block 23 abuts against the tail ends of the plurality of wire cores of the to-be-tested connector 6, and each electrical testing probe is inserted into each pin of the male head of the to-be-tested connector 6, thereby forming a circuit loop for detecting the to-be-tested connector 6; specifically, the electrical testing part 32 is electrically connected with a power supply, and after the current flows from the positive electrode of the power supply to the electrical testing probe, the to-be-tested connector 6, the metal block 23, a measuring instrument and the negative electrode of the power supply, the voltage and current parameters read by the measuring instrument are output, thereby completing the detection of the to-be-tested connector 6.

[0055] It can be understood that the electric test probe of the utility model embodiment is one-to-one corresponding to the male pin of the connector 6 to be tested, so as to ensure that each electric test probe can be accurately and stably inserted into each pin during the test.

[0056] According to Figure 1 As shown in the figure, the swing assembly 4 includes a third driver 41 and a wire harness clamping part 42, and the power output shaft of the third driver 41 is drivingly connected with the wire harness clamping part 42.

[0057] Specifically, when the metal block 23 abuts against the tail ends of the plurality of wire cores of the connector 6 to be tested, and the electric test probe is inserted into each pin, the wire harness clamping part 42 is moved downward by the power output shaft of the first driver 21 to be able to fixedly clamp the wire harness of the connector, so as to prevent the wire harness of the connector from easily falling off, and then the wire harness clamping part 42 is repeatedly moved upward or downward by the power output shaft of the third driver 41, so as to simulate the use environment of the connector 6 to be tested under vibration, swing or movement, and detect whether the internal circuit of the connector 6 to be tested appears disconnection, poor contact and the like, and whether the connector 6 to be tested can still maintain stable conductivity.

[0058] It should be noted that the frequency of the repeated upward or downward movement of the wire harness clamping part 42 can be controlled by the power output shaft of the third driver 41 according to the preset movement frequency and times, for example, the frequency of each upward or downward movement is 10-50 times per minute, and the specific frequency is not limited herein.

[0059] According to Figure 3 As shown in the figure, in some specific embodiments, the wire harness clamping part 42 includes a fourth driver 421, a first clamping block 423, a second clamping block 424 and a support block 425; the power output shaft of the third driver 41 is drivingly connected with the fourth driver 421; the first clamping block 423 is fixedly arranged on the side surface of the support block 425, the second clamping block 424 is rotatably arranged on the side surface of the support block 425 through a rotating shaft, and the power output shaft of the fourth driver 421 is drivingly connected with the second clamping block 424.

[0060] Specifically, if the wire harness clamping portion 42 needs to be fixedly clamped to the wire harness of the connector, the power output shaft of the third driver 41 pushes the fourth driver 421 to move downward to a specified position, and then the second clamping block 424 is moved away from the first clamping block 423 by the fourth driver 421 until the wire harness of the to-be-tested connector 6 is located between the first clamping block 423 and the second clamping block 424, and then the power output shaft of the fourth driver 421 is reset to move to drive the second clamping block 424 to move close to the first clamping block 423 until the first clamping block 423 and the second clamping block 424 can simultaneously fixedly clamp the wire harness of the to-be-tested connector 6, and finally the power output shaft of the third driver 41 pulls and pushes the fourth driver 421 to make the wire harness of the to-be-tested connector 6 clamped by the first clamping block 423 and the second clamping block 424 continuously ascend and descend, thereby simulating the use environment of the wire harness of the to-be-tested connector 6 subjected to vibration, swing or movement.

[0061] According to Figure 3 As shown in the further embodiment, one end of the power output shaft of the fourth driver 421 is provided with a pushing portion 422; the wire harness clamping portion 42 further comprises a connecting rod 426, one end of the connecting rod 426 is rotationally connected with the pushing portion 422, and the other end of the connecting rod 426 is rotationally connected with the second clamping block 424.

[0062] Specifically, in order to stably clamp the wire harness of the to-be-tested connector 6, when the power output shaft of the fourth driver 421 drives the pushing portion 422 to move downward, the pushing portion 422 is used to push the entire connecting rod 426 to move downward, and in this process, since the connecting rod 426 is rotationally connected with the pushing portion 422, the pushing portion 422 is converted into a pushing action on the second clamping block 424 through the connecting rod 426, at this time, the second clamping block 424 is rotated through the rotating shaft until the second clamping block 424 cooperates with the first clamping block 423 to fixedly clamp the wire harness of the to-be-tested connector 6, and vice versa, when the power output shaft of the fourth driver 421 drives the pushing portion 422 to move upward, the pushing portion 422 is used to pull the connecting rod 426 to move upward, and the second clamping block 424 is pulled to rotate away from the first clamping block 423 until the wire harness of the to-be-tested connector 6 can be released.

[0063] It should be noted that the pushing portion 422 is provided with a first rotating shaft, the second clamping block 424 is provided with a second rotating shaft, one end of the connecting rod 426 is rotationally arranged on the first rotating shaft, and the other end of the connecting rod 426 is rotationally arranged on the second rotating shaft.

[0064] According to Figure 3As shown, in a further embodiment, the side of the first clamp block 423 opposite to the second clamp block 424 is formed with a first recess 4231, and the side of the second clamp block 424 opposite to the first clamp block 423 is formed with a second recess 4241; when the second clamp block 424 is rotated to abut against the first clamp block 423, a clamping opening for clamping the wires of the connector under test 6 is formed.

[0065] Specifically, as shown in the drawings, when the wire harness of the connector under test 6 is clamped, since the first clamp block 423 is located above the second clamp block 424, the first recess 4231 is formed on the bottom surface of the first clamp block 423, and the second recess 4241 is formed on the top surface of the second clamp block 424; when the second clamp block 424 is pulled to rotate to abut against the bottom surface of the first clamp block 423 by the power output shaft of the fourth driver 421, the first recess 4231 and the second recess 4241 form a clamping opening, so that the wire harness of the connector under test 6 can be accurately clamped in the clamping opening, and the wire harness can be prevented from easily shaking or deviating; if the second clamp block 424 is rotated away from the first clamp block 423, the wire harness can be separated from the clamping opening.

[0066] It can be understood that the clamping opening formed by the first recess 4231 and the second recess 4241 is in the shape of a waist hole, which can improve the clamping force on the wire harness of the connector under test 6, and can also stably clamp wire harnesses of different sizes.

[0067] According to Figure 1 As shown, in some specific embodiments, the electrical testing device further comprises a second pressing assembly 5, which comprises a fifth driver 51 and a second pressing part 52; the power output shaft of the fifth driver 51 is drivingly connected with the second pressing part 52.

[0068] Specifically, since the tail ends of the wire cores of the connector under test 6 are relatively weak and are prone to be damaged due to collision with other components during testing, when the lifting seat 22 is lowered to abut against the metal block 23 and the tail ends of the wire cores of the connector under test 6 by the first driver 21, the second pressing part 52 is pushed upward by the power output shaft of the fifth driver 51 until the second pressing part 52 abuts against the bottom surface of the metal block 23, so that the tail ends of the wire cores of the connector under test 6 are clamped and fixed between the second pressing part 52 and the metal block 23, which can prevent the tail ends of the wire cores from deviating during testing and being damaged due to collision with other components, thereby protecting the integrity of the tail ends of the wire cores.

[0069] In further embodiments, the second pressing portion 52 is made of soft material. Specifically, when the second pressing portion 52 cooperates with the metal block 23 to fixedly clamp the tail ends of the cores of the connector 6 under test, since the second pressing portion 52 is made of soft material, it has the ability to deform and can evenly distribute the pressure when the tail ends of the cores are pressed, thereby avoiding crushing the tail ends of the cores due to excessive local pressure.

[0070] It can be understood that the second pressing portion 52 of the embodiments of the present application is a rubber block or a silicone block, and the specific type is not limited herein.

[0071] In some specific embodiments, an elastic member is arranged between the metal block 23 and the lifting seat 22.

[0072] Specifically, in order to prevent the power output shaft of the first driver 21 from being pressed to move the lifting seat 22 to a position where the metal block 23 exerts a greater force on the tail ends of the cores, thereby crushing the tail ends of the cores, when the second pressing portion 52 cooperates with the metal block 23 to fixedly clamp the tail ends of the cores of the connector 6 under test, the elastic member arranged between the metal block 23 and the lifting seat 22 can be understood as a spring, i.e. by the compression and rebound characteristics of the spring, thereby absorbing and dispersing the swinging force exerted by the metal block 23 on the tail ends of the cores, ensuring that when the second pressing portion 52 cooperates with the metal block 23 to fixedly clamp the tail ends of the cores of the connector 6 under test, the tail ends of the cores will not be subjected to a large pressing force, thereby avoiding damage to the cores.

[0073] According to Figure 4 As shown in FIG. 5, the side surface of the metal block 23 opposite to the second pressing portion 52 is formed with a plurality of connection grooves 231 electrically connected to the tail ends of the cores of the connector 6 under test, respectively.

[0074] Specifically, by arranging a plurality of connection grooves 231 on the side surface of the metal block 23, each corresponding to a tail end of a core of the connector 6 under test, i.e. each tail end of a core is connected to a given connection groove 231, this arrangement can simultaneously test a plurality of tail ends of cores, compared to the conventional method of sequentially and individually connecting and disconnecting each tail end of a core for testing, the embodiments of the present application can further improve the overall testing efficiency, in addition, it can also disperse the pressure applied to the tail ends of the cores and reduce stress concentration at a single point, thereby reducing the risk of damage to the cores.

[0075] The above description is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements shall be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
