[0046] Figure 1 A three-dimensional diagram showing a wiring harness plug detection tool provided by an embodiment of the present disclosure, Figure 2 for Figure 1 The top view of the wiring harness plug detection tooling is shown in Figure 1 and 2 As shown, the wiring harness plug detection tool provided by the embodiment of the present disclosure includes:

[0047] The machine platform 1 provided with a probe 10 is used to cooperate with a wiring harness plug to make electrical contact with the wiring harness plug through the probe 10 .

[0048] Combination Figure 3 and 4 As shown, Figure 3 for Figure 1 The exploded view of the wiring harness plug inspection tooling is shown. Figure 4 for Figure 1 The cross-sectional view of the wiring harness plug detection tool shown in the figure, the wiring harness plug detection tool also includes:

[0049] The ejector structure 11 is arranged in the machine 1, and is arranged to be pressed by the wiring harness plug to move from the initial position to the target position when the machine 1 is matched with the wiring harness plug, and reset to the initial position when the wiring harness plug is separated from the machine 1;

[0050] The sensor 12 located below the machine platform 1 is used to sense that the ejector structure 11 has reached a target position.

[0051] Using the wiring harness plug detection tool provided in this embodiment, combined with Figure 5 As shown, the detection circuit is connected to the bottom of the probe 10. When the wiring harness plug 2 to be detected is inserted into the machine 1, the ejector structure 11 is pressed downward at the same time. The sensor 12 senses that the ejector structure 11 reaches the target position, that is, the wiring harness plug 2 reaches the test position. At this time, a stable contact connection is formed between the wiring harness plug 2 and the probe 10, and the electrical performance detection of the wiring harness plug 2 is controlled to start.

[0052] Therefore, by utilizing the position sensing cooperation between the ejector pin structure 11 and the sensor 12, the position of the wiring harness plug 2 inserted into the machine 1 can be accurately detected, ensuring that the ejector pin structure 11 of the wiring harness plug 2 is in good contact and the test effect is stable, thereby avoiding large fluctuations in the test effect due to the wiring harness plug 2 not being properly inserted, and further improving the detection accuracy of the wiring harness plug.

[0053] In one implementation of the present disclosure, Figure 4 As shown, the ejector pin structure 11 includes:

[0054] The rod-shaped body 111 and the spring 112 connected with the rod-shaped body 111 are connected in a matching manner as follows:

[0055] The ejector pin structure 11 is supported by the wiring harness plug 2 (such as Figure 5 As shown in the figure, the rod 111 is pressed to move from the initial position to the target position and compress the spring 112 to elastically deform. When the wiring harness plug 2 is separated from the machine 1, the spring 112 recovers its deformation to drive the rod 111 to return to the initial position.

[0056] The ejector pin structure 11 of this embodiment is a spring ejector pin. In the initial position, the ejector pin head of the rod-shaped body 111 is exposed upward, and the spring 112 is not deformed or has a relatively low deformation. When the wiring harness plug 2 moves downward, it contacts and continues to press the ejector pin head, so that the rod-shaped body 111 moves downward to the target position, and the spring 112 is greatly deformed in the process. When the test is completed, the wiring harness plug 2 is pulled upward, and the spring 112 recovers its deformation, prompting the rod-shaped body 111 to move upward until the ejector pin head is exposed again, and the rod-shaped body 111 returns to the initial position.

[0057] By using the ejector pin structure 11 of the present embodiment, the wiring harness plug 2 can be inserted into the machine 1 in place, and the machine 1 can be repeatedly used to detect the wiring harness plug 2 .

[0058] In an optional embodiment of the present disclosure, if Figure 4 As shown, the spring 112 is sleeved outside the rod-shaped body 111, one end of the spring 112 abuts against the ejector pin of the rod-shaped body 111 and the other end is provided with a movement limiting structure.

[0059] In this way, when the rod-shaped body 111 is pressed and moves downward, the spring 112 is also pressed by the ejector pin head, and the movable limiting structure prevents the spring 112 from moving downward as a whole, so that the spring 112 is compressed and deformed.

[0060] In an alternative embodiment, if Figure 4-5 As shown, the ejector pin structure 11 further includes:

[0061] The housing 113 is enclosed in the machine 1; the spring 112 ( Figure 5 The movable limiting structure is the bottom of the shell 113.

[0062] In this embodiment, the spring 112 is encapsulated in the housing 113, and the ejector structure 11 is encapsulated in the machine 1 through the housing 113, thereby improving the integration and stability of the ejector structure 11. The bottom of the housing 113 and the machine 1 are fixedly connected to realize the movable limit structure. In this case, the ejector structure 11 can use prefabricated parts to reduce the product manufacturing cost.

[0063] In another optional embodiment, the movement limiting structure is formed on a stopper (not shown in the figure) disposed in the machine, and the downward movement of the spring is limited by the stopper.

[0064] In an optional embodiment of the present disclosure, the ejector pin structure may also use a pneumatic ejector pin.

[0065] like Figure 3-Figure 5 As shown, in the embodiment of the present disclosure, the sensor 12 includes:

[0066] A sensing unit 120 disposed in the machine 1 and below the ejector structure 11;

[0067] The external terminal 121 disposed outside the machine 1 and connected to the sensing unit 120 is configured to transmit a position sensing signal of the sensing unit 120 .

[0068] In this case, when the ejector structure 11 moves downward to the target position, it is sensed by the sensing unit 120, which then generates a position sensing signal and promptly sends it to the testing organization through the external terminal 121. In this embodiment, the sensor 12 is entirely encapsulated in the machine 1 and is electrically connected to the external testing organization through the external terminal 121.

[0069] The sensor 12 of this embodiment can use a prefabricated part, which can reduce the manufacturing cost of the wiring harness plug detection tooling. As an example, the sensor 12 can use a proximity sensor or a pressure sensor. Among them, the proximity sensor (English: proximity sensor), also known as a proximity sensor, is a sensor that can detect the presence of objects nearby without contact. The proximity sensor realizes its function by emitting an electromagnetic field or an electromagnetic radiation beam (such as infrared rays) and observing the changes in the electric field or the return signal. The object that can be detected is called the target of the proximity sensor, such as the ejector structure 11 of this embodiment. Among them, different types of proximity sensors have different targets. For example, a capacitive proximity sensor or a photoelectric sensor may detect a plastic target, while an inductive proximity sensor can only detect a metal target.

[0070] Among them, the pressure sensor detects the position by sensing the pressure through contact with the object to be measured.

[0071] In the embodiments of the present disclosure, reference Figure 3-Figure 5 An exposed top block 13 is provided in the machine 1, and the top block 13 is configured to push open the wiring harness plug 2 when it is in the target position ( Figure 2 A secondary lock 20 in the wiring harness plug 2 is provided to lock the wiring harness plug 2.

[0072] In this embodiment, the top block 13 and the secondary lock 20 (such as Figure 5 As shown in the figure, the top block 13 pushes open the secondary lock 20, and locks the secondary lock 2 inside it while the wiring harness plug 2 is inserted, so that one action completes one more process, improves efficiency, and at the same time maintains the position stability of the wiring harness plug 2 during testing and the stable connection between the wiring harness plug 2 and the machine 1.

[0073] At the same time, when the ejector block 13 pushes the secondary lock 20, it indicates that the ejector structure 11 has also reached the target position, and the sensor 12 generates a position sensing signal. Therefore, the sensor 12 also plays a role in detecting the locking state of the wiring harness plug 2, further accurately ensuring the stability of the wiring harness plug 2.

[0074] like Figure 1 and 2As shown, the wiring harness plug detection tool also includes:

[0075] The pressure claw structure 14 is hingedly connected to the machine table 1, and has an operating end 14a and a pressure claw end 14b located at both ends of the hinged connection position. The pressure claw structure 14 is configured to rotate between a first position and a second position through a hinged connection, wherein when rotating from the second position to the first position, the pressure claw end 14b gradually approaches the position of the probe 10 and the ejector pin structure 11 on the machine table 1 from top to bottom.

[0076] In this way, the pressing claw structure 14 is rotated to the second position by operating the operating end 14a to turn the wiring harness plug 2 (such as Figure 5 As shown in the figure, the wire harness plug 2 is plugged into the machine platform 1, and then the pressing claw structure 14 is operated to rotate to the first position, so that the pressing end 14b presses the wire harness plug 2 tightly on the machine platform 1.

[0077] In this embodiment, after the wiring harness plug 2 is inserted into the machine 1, considering that the probe 10 may have less elasticity and generate a force to push the wiring harness plug 2 upward, the clamping claw structure 14 is used to press the wiring harness plug 2 to fix the wiring harness plug 2 in place, ensuring that the wiring harness plug 2 can always be in full contact during the test, so as to maintain the stability of the test process and ensure the test results.

[0078] like Figure 1 and 2 As shown, a wiring harness plug 2 (such as Figure 5 The probe 10 and the ejector pin structure 11 are arranged at the position of the slot 1a. In this case, the wiring harness plug 2 can be partially accommodated in the slot 1a, and the slot 1a plays a certain role in limiting the wiring harness plug 2, further maintaining the test stability.

[0079] In one implementation, the slot 1a is configured to form a shape fit with the harness plug 2. The shape fit ensures that the harness plug 2 is easy to insert, prevents the harness plug 2 from shaking in the tooling, causes poor contact between the probe 10 and the needle in the harness plug 2, affects the test results, and prevents the wrong type of harness plug from being inserted.

[0080] like Figure 4 and Figure 5 As shown, a boss 15 is provided in the slot 1a, the probe 10 is provided on it, and the ejector head of the ejector structure 11 and the ejector block 13 are both located in the slot 1a around the boss 15. The boss 15 isolates the probe 10 from the ejector structure 11 and the ejector block 13.

[0081] In the embodiments of the present disclosure, Figure 4 As shown, the probe 10 is designed as a spring probe, and the wiring harness plug 2 (such as Figure 5When the test circuit is connected and the circuit resistance is detected, the needle in the harness plug 2 contacts the needle of the elastic probe to prevent the needle of the harness plug 2 from contacting with the harness plug detection tooling over a large area, which may damage the needle of the product.

[0082] Using the elastic probe, when the harness plug 2 is inserted into the machine 1, the plug in the harness plug 2 contacts the needle of the elastic probe and moves the needle of the elastic probe downward, and then pops out when the harness plug 2 is separated.

[0083] like Figure 1-5 As shown, the machine 1 provided in the embodiment of the present disclosure is provided with two wiring harness plug detection positions, and a probe 10, a ejector structure 11, a sensor 12, an ejector block 13 ( Figure 1 and Figure 2 Not shown) and the pressing claw structure 14, so that two sets of wiring harness plugs 2 (such as Figure 5 In another embodiment, one or more wiring harness plug detection devices may be provided in the machine 1, which is not limited here.

[0084] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
