Description

TECHNICAL FIELD

[0001] The utility model relates to the field of wire rod detection, especially a wire rod detection equipment with stable contact. BACKGROUND

[0002] In modern industrial production, wire rod is an important carrier for power transmission and signal transmission, and its quality directly affects the performance and stability of various electrical equipment. Therefore, it is crucial to detect wire rod efficiently and accurately. Traditional wire rod detection equipment often faces the problem of low detection efficiency during the detection process. Because the detection interface is not designed reasonably, the wire rod may not be in good contact after being inserted into the detection port, resulting in inaccurate detection results and the need for repeated detection, which wastes a lot of time and manpower. Moreover, the process of withdrawing the wire rod from the detection equipment after detection is completed is also relatively cumbersome, further reducing the detection efficiency. In addition, when the detection wire rod interface is not fully inserted, the traditional equipment cannot effectively prevent the power from being turned on, which not only causes the deviation of the detection result, but also may cause safety hazards such as electric sparks due to poor contact, posing a potential threat to the operator and the equipment. The existing wire rod detection equipment has deficiencies in detection efficiency, detection accuracy, and safety, and a new type of wire rod detection equipment that can realize efficient, safe, and stable detection is needed to meet production needs. For example, the patent with publication number CN204882775U discloses a wire and cable conduction detection equipment. The interface of this device has the following deficiencies in the detection field: it cannot turn off the power when the contact is poor, which will affect the detection quality. SUMMARY

[0004] In view of the deficiencies of the prior art, the utility model aims to provide a wire rod detection equipment with stable contact, which solves the problems existing in the prior art. By carefully designing the detection port and using the magnetic attraction structure to realize fast and stable connection and separation, the detection efficiency is improved. The problem of inaccurate detection results caused by poor contact after the wire rod is inserted due to poor design of the detection interface is solved. The magnetic attraction structure is used to ensure that the power is turned on only when the detection wire rod interface is fully inserted, avoiding inaccurate detection caused by poor contact. The problem that the traditional equipment cannot prevent the power from being turned on when the detection wire rod interface is not fully inserted, which may cause safety hazards such as electric sparks due to poor contact, is overcome.

Detailed Implementation

[0023] The following will refer to the appendix in the example of this utility model. Figure 1 - Appendix Figure 7 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figure 1 As shown, this utility model provides a technical solution: a stable contact wire testing device, including a continuity tester 1, an electrical box 2 fixed to the lower end of the continuity tester 1, and a detection port 3 fixed to the side of the electrical box 2. The continuity tester 1 is the core testing component of the entire wire testing device. It is used to detect the continuity of the wire. By working in conjunction with the electrical box 2 and the detection port 3, it determines whether the wire can conduct electricity normally, thereby determining whether the wire meets quality standards. It can provide technical support for wire testing, and its test results are a key basis for judging wire quality, which is an important link in ensuring the quality of wire production. The electrical box 2 provides power support to the continuity tester 1 on the one hand, ensuring that the tester can work normally; on the other hand, it is connected to the detection port 3, acting as an intermediary for power transmission, transmitting appropriate current to the detection port 3 for wire testing. The detection port 3 is the part that directly contacts the wire being tested. Through the coordinated work of multiple internal components, it achieves efficient and stable wire testing, and is the key structure for achieving stable contact testing of wires.

[0025] like Figure 2 and Figure 7As shown, the detection port 3 includes a housing 301 fixed to the side of the electrical box 2, an electromagnet 302 fixed to the rear end of the housing 301, an actuating mechanism 303 mounted on the side of the housing 301, a magnetic ring 304 mounted inside the housing 301, and a magnetic contact plate 305 mounted at the center of the housing 301. The housing 301 serves as the outer shell structure of the detection port 3, fixing and protecting the internal components. It provides a stable working environment for the various components inside the detection port 3. Through reasonable structural design, it ensures the coordinated operation between the components, enabling the detection port 3 to stably complete the wire testing task. The electromagnet 302 generates a magnetic field when energized, interacting with the magnetic ring 304 and the magnetic contact plate 305. During the testing process, the magnetic contact plate 305 can be activated by controlling the on / off state of the electromagnet 302, thereby controlling the contact and separation of the wire with the testing equipment. Simultaneously, the movement of the magnetic ring 304 is controlled, attracting the action mechanism 303 to lock the interface M being tested. The action mechanism 303 ensures that the interface M is locked during testing, thus guaranteeing testing stability. Upon completion of testing, the interface M can be released, enabling convenient replacement. The magnetic ring 304, through its interaction with the electromagnet 302, controls the clamping and releasing of the action mechanism 303 on the interface M being tested. The magnetic contact plate 305, through its interaction with the electromagnet 302, ensures stable and safe contact of the interface.

[0026] like Figure 3 and Figure 7 The shown actuation mechanism 302 includes a fixed plate 3021 screwed onto a housing 301, a movable block 3022 installed inside the fixed plate 3021, a guide post 3023 fixed inside the movable block 3022, and a first spring 3024 fixed outside the guide post 3023. The fixed plate 3021 is used to fix the actuation mechanism 303 onto the housing 301. The movable block 3022 can move within a certain range and is attracted by a magnetic ring 304. When the magnetic ring 304 is attracted to the bottom, it attracts the movable block 3022 to clamp the detected interface M. The guide post 3023 is connected to the movable block 3022 to guide the movement direction of the movable block 3022. The first spring 3024 provides elastic force. When an external force is applied, the movable block 3022 can compress the first spring 3024 under the guidance of the guide post 3023, and return to its original state by the spring force after the force disappears, while simultaneously pushing the movable block 3022 to reset. (Contact clamping force.)

[0027] like Figure 4 and Figure 7As shown, the magnetic contact plate 305 has a contact groove 3053 on its surface corresponding to the 17-pin connector, and a conductive post 3052 at its bottom. A second spring 3051 is located on the outside of the conductive post 3052. The contact groove 3053, corresponding to the 17-pin connector, is used to ensure good contact with the interface of the wire being tested. The conductive post 3052 at the bottom is used to conduct current, thereby realizing the continuity detection of the wire. The second spring 3051 on the outside of the conductive post 3052 provides elastic force. When the interface M to be tested is inserted, the contact groove 3053 contacts the pin. At this time, the electromagnet 302 attracts the magnetic ring 304. After the magnetic ring moves to the bottom, the attraction mechanism 303 clamps the interface M to be tested. At this time, the electromagnet 302 repels the magnetic contact plate 305, so that the pin is in tight contact with the contact groove 3053, ensuring the stability of the contact. Furthermore, when the interface M to be tested is not fully inserted, the repulsive force between the second spring 3051 and the electromagnet 302 will prevent the conductive post 3052 from contacting the conductive groove 3016, and testing will not be possible.

[0028] like Figure 5 and 6 As shown, the side of the housing 301 is uniformly provided with motion holes 3011, and a limit plate 3012 is provided on the outside of the motion holes 3011. The side of the housing 301 is provided with threaded holes 3013. The motion holes 3011 uniformly provided on the side provide movement space for the movable block 3022. The limit plate 3012 on the outside is used to limit the movement range of the movable block 3022, and the threaded holes 3013 are used to fix the fixing plate 3021.

[0029] like Figure 6 and Figure 7 As shown, a limiting groove 3014 is provided inside the housing 301, and a conductive groove 3016 is provided in the center of the housing 301. The limiting groove 3014 cooperates with the protrusion on the interface M to ensure that the interface M is inserted correctly. The conductive groove 3016 contacts the conductive post 3052 for conducting electricity.

[0030] like Figure 6 and 7 As shown, the upper end of the limiting groove 3014 is provided with a large-angle chamfer 3015; the presence of the chamfer 3015 makes the insertion of the interface M to be tested more convenient and accurate.

[0031] Working principle:

[0032] Pre-test preparation stage

[0033] In the initial state of the equipment, the electromagnet 302 is de-energized. In its natural state, the magnetic contact plate 305 has the conductive post 3052 and the conductive groove 3016 in a non-contact or loosely contacting state. The movable block 3022 in the actuation mechanism 303 is in its initial position under the elastic force of the first spring 3024 and does not clamp the interface M being detected.

[0034] Wire insertion stage

[0035] When the interface M to be tested is inserted into the test port 3, firstly, the chamfer 3015 at the upper end of the limiting groove 3014 inside the housing 301 allows the interface M to be inserted more conveniently and accurately. The limiting groove 3014 cooperates with the protrusion on the interface M to ensure that the interface M is inserted correctly.

[0036] As the interface M to be tested is inserted, the contact groove 3053 on the magnetic contact plate 305 begins to contact the pins of the interface M to be tested. At this time, due to the insertion of the interface M to be tested, a certain pressure is generated on the magnetic contact plate 305, causing the conductive post 3052 to tend to move closer to the conduction groove 3016, but it is not yet fully conductive.

[0037] Initial stage of detection

[0038] Once the interface M being tested is inserted to a certain extent, the electromagnet 302 is energized. The energized electromagnet 302 generates a magnetic field, which attracts the magnetic ring 304 towards it.

[0039] As the magnetic ring 304 moves toward the electromagnet 302, it attracts the movable block 3022 in the actuation mechanism 303. Under the attraction of the magnetic ring 304, the movable block 3022 overcomes the elastic force of the first spring 3024 and moves along the guide post 3023 toward the interface M to be detected, thereby clamping the interface M to be detected and ensuring the stability of the interface M to be detected during detection.

[0040] Simultaneously, the magnetic field generated by the electromagnet 302 repels the magnetic contact plate 305, causing the pins on the magnetic contact plate 305 to make tight contact with the contact groove 3053, and the conductive post 3052 to make tight contact with the conductive groove 3016, thereby achieving current conduction. The continuity tester 1 then begins to test the wire. If the interface M being tested is not fully inserted, the repulsive force between the second spring 3051 and the electromagnet 302 will break the contact between the conductive post 3052, making testing impossible. This avoids testing under conditions of poor contact.

[0041] Testing completion stage

[0042] After the test is completed, the magnetism of the electromagnet 302 is reversed. The magnetic ring 304 can push the tested interface M to move outward, and the movable block 3022 in the action mechanism 303 returns to its initial position under the elastic force of the first spring 3024, releasing the tested interface M.

[0043] The magnetic contact plate 305 is attracted by the electromagnet 302 and quickly disconnects from the pin. The interface M to be tested can be easily pulled out from the test port 3, completing the entire test process.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
