Description

Technical Field

[0001] This application relates to the field of terminal block testing technology, and in particular to a signal connector for rapid testing. Background Technology

[0002] Terminal blocks are used to facilitate the connection of wires. They are actually a metal plate encased in insulating plastic, with holes at both ends for inserting wires and screws for tightening or loosening. For example, if two wires need to be connected sometimes and disconnected at other times, they can be connected with terminals and disconnected at any time without having to solder or twist them together, which is very convenient and quick.

[0003] To ensure the stability and reliability of terminal block operation, it is necessary to test it during the production process. Traditional testing methods involve inserting probes for the input signal into each channel sequentially for testing, which requires sequential wiring and disconnection operations for each channel. This testing method is inefficient and also carries the possibility of misoperation. Therefore, how to improve the existing signal connector to overcome the above problems is an urgent problem to be solved by those skilled in the art. Utility Model Content

[0026] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0028] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0029] One preferred embodiment of this application, such as Figures 1 to 8 As shown, a signal connector for rapid testing includes a base 1, a drive device 2, a mounting plate 3, and multiple test probes 4. The base 1 is provided with a placement station 11 for placing the terminals 5. The drive device 2 is mounted on the base 1, and the mounting plate 3 is mounted on the output end of the drive device 2. The test probes 4 are retractable and are located on the side of the mounting plate 3. Of course, the number and position of the test probes 4 correspond to the multiple channels 501 of the terminals 5 to be tested.

[0030] Understandably, during testing, the drive device 2 extends through the mounting plate 3 to simultaneously insert all the test probes 4 into the corresponding channels 501 of the terminal block 5. Furthermore, the inserted test probes 4, under the action of the extension and retraction force, all abut against each other within the channel 501. Therefore, the advantages of this signal connector design compared to existing technologies are: ① Simultaneous testing by multiple test probes 4 greatly improves testing efficiency, avoiding the tedious steps of wiring and disconnecting wires from each channel 501 in traditional testing methods, reducing the possibility of misoperation. ② The retractable design of the test probes 4 ensures stable contact between the test probes 4 and the channels 501 of the terminal block 5, improving the accuracy and reliability of the testing. ③ Different channels 501 may have different depths; the retractability of the test probes 4 can adapt to the testing needs of channels 501 with different depths, enhancing the flexibility of the device. ④ Driven by the drive device 2, the operation of the test probes 4 can be automated, reducing manual operation steps and improving testing efficiency.

[0031] It should be noted that how the detection probe 4, the wiring terminal 5, and the detection equipment form a detection signal circuit through wiring is common knowledge in the art. Furthermore, since this application is primarily for protecting mechanical devices, the detection principle and circuit connection will not be explained in detail here. Additionally, the specific structure and working principle of the drive device 2 are also well-known to those skilled in the art, and therefore will not be described in detail here. Common drive devices 2 include hydraulic cylinders, pneumatic cylinders, and linear motors, etc., which can be selected by those skilled in the art according to actual needs.

[0032] This application does not specifically limit the retractable structure of the detection probe 4. The following are two specific embodiments for reference:

[0033] Structure 1: The detection probe 4 is slidably mounted on the side of the mounting plate 3, and the detection probe 4 and the mounting plate 3 are connected by an elastic element. Understandably, during detection, the detection probe 4, under the action of the driving device 2, extends into the channel 501 of the terminal 5 and is compressed and moved. At this time, the elastic element is compressed, generating elastic force. This elastic force ensures that the detection probe 4 and the channel 501 are in close contact, guaranteeing a stable contact connection between the two.

[0034] Specifically, such as Figure 3As shown, the elastic element is preferably a spring 8; a retaining ring 10 is provided at both ends of the detection probe 4, and the detection probe 4 is inserted through the mounting plate 3, with the two retaining rings 10 respectively located on both sides (beside) of the mounting plate 3. The spring 8 is sleeved on the outside of the detection probe 4, and the two ends of the spring 8 abut against the mounting plate 3 and one of the retaining rings 10 respectively. This installation method facilitates the quick installation of the detection probe 4. For example, the retaining ring 10 near the head end of the detection probe 4 is threaded and detachable. During installation, the detection probe 4 is inserted from the side of the mounting plate 3, then the spring 8 is sleeved on the detection probe 4, and finally the retaining ring 10 is tightened to complete the installation of the detection probe 4. Furthermore, this installation method does not use screws or other fixing methods, resulting in high assembly and disassembly efficiency.

[0035] Structure 2: such as Figure 4 As shown, the detection probe 4 includes a needle body 401 and a detection head 402. The needle body 401 can be fixedly installed (e.g., bolted) at the side of the mounting plate 3 via its first end, while the detection head 402 can be elastically slidably installed at the second end of the needle body 401. For example, the detection head 402 can be telescopically positioned within the needle body 401 via a miniature spring. Similarly, during detection, when the detection head 402 is inserted into the channel 501 of the terminal 5, it will retract under pressure. Furthermore, under the elastic force of the miniature spring, the detection head 402 can make tight contact with the channel 501 of the terminal 5, further ensuring a stable contact connection between the two.

[0036] It should be noted that with Structure 1, the overall movement of the detection probe 4 allows for a larger extendable stroke and a wider detection range; furthermore, the spring 8 is externally mounted, facilitating easy detection and rapid repair in case of malfunction. The disadvantage is that its tail needs to connect to the detection circuit, so the movement of the detection probe 4 will also exert a pulling effect on the detection circuit, potentially leading to loosening or wear of the circuit over prolonged use. Structure 2, on the other hand, allows for miniaturization of the detection head 402, enabling it to extend and retract within the needle body 401. This design reduces the pulling on the detection circuit and improves its lifespan; however, its extendable stroke may be limited by the length of the needle body 401, resulting in a relatively smaller detection range. Both structures can meet practical needs, and those skilled in the art can choose according to their specific detection requirements.

[0037] In one embodiment of this application, such as Figure 7 As shown, different detection probes 4 can form probe groups, thereby adapting to the detection of different specifications of wiring terminals 5. For example: ① First type of wiring terminal 5: the spacing between adjacent channels 501 is d1, while... Figure 7The spacing between adjacent detection probes 4 is also d1, so they can be used interchangeably. ② Second type of terminal block 5: The spacing between adjacent channels 501 is d2, where d2 is equal to twice d1. This means that multiple adjacent detection probes 4 spaced one space apart can be used to detect this type of terminal block 5. Similarly, assuming d3 is equal to three times d1, multiple adjacent detection probes 4 spaced two spaces apart can be used to detect this type of terminal block 5.

[0038] It should be noted that the reason why different types of terminal blocks 5 can be tested in the above embodiments is due to the retractable structure of the detection probe 4. Unused detection probes 4 will retract during compression, thus preventing interference during the testing process. However, in practical use, it should be noted that unused detection probes 4 do not need to be wired. Furthermore, it is best to use the corresponding type of detection probe 4 for the corresponding terminal block 5. For example, the second type of terminal block 5 can share a detection device with the first type of terminal block 5, with an adjacent detection probe spacing of d1. However, during testing, many detection probes 4 will have a large amount of expansion and contraction during compression due to the lack of channel 501, which will reduce the lifespan of the detection probes 4 over time.

[0039] like Figure 3 and Figure 4 As shown, the tip of the detection probe 4 is preferably tapered. This tapered design facilitates easier insertion of the detection probe 4 into the channel 501 of the terminal 5, reducing resistance during insertion and improving detection efficiency. Simultaneously, the tail end of the detection probe 4 is equipped with a quick-connect interface 9 for connection to the circuit. This quick-connect interface 9 allows for convenient and rapid connection and disconnection between the detection probe 4 and the detection equipment. For example, connectors on the detection circuit can be plugged into the quick-connect interface 9, further enhancing the convenience of the detection operation. Furthermore, the design of the quick-connect interface 9 ensures the stability and reliability of the connection between the detection probe 4 and the detection circuit, avoiding detection errors caused by poor connection.

[0040] Furthermore, such as Figure 5As shown, to facilitate the testing of different models of terminal blocks 5, the mounting plate 3 is detachably installed to the output end of the drive device 2 via the connector 7. Specifically, a push plate is fixedly installed at the output end of the drive device 2, and the connector 7 is fixedly installed on the push plate by bolts. The mounting plate 3 is then fixedly installed on the connector 7 by bolts. Disassembly is performed simply by detaching the mounting plate 3 from the connector 7. The length of the connector 7 corresponds to the length of the mounting plate 3, providing stable support for the mounting plate 3. This detachable installation method allows users to easily replace the mounting plate 3 with the corresponding model of the terminal block 5 to be tested, thus adapting to different testing needs.

[0041] Furthermore, such as Figure 3 As shown, the mounting plate 3 can be made of a transparent insulating material (such as acrylic sheet). Its advantages include: facilitating observation by testing personnel of the contact between the testing probe 4 and the channel 501 (due to its good light transmittance), and real-time observation of the extension and retraction of the testing probe 4, thereby ensuring the accuracy and reliability of the test; simultaneously, the transparent insulating material also ensures the safety of the testing process, avoiding safety hazards caused by the material's conductivity. Additionally, a carved hole 6 can be provided on the side of the mounting plate 3 for mounting the testing probe 4. Specifically: for structure one of the testing probe 4, the testing probe 4 is inserted into the carved hole 6; for structure two of the testing probe 4, the probe body 401 can be fixedly installed through the carved hole 6 and the engagement of a screw / bolt.

[0042] In this embodiment, as Figure 6 As shown, the base 1 includes an integrally formed horizontal section 101 and a vertical section 102, i.e., the base 1 has an "L" shaped structure. The drive device 2 is installed on the horizontal section 101, and a placement station 11 is formed at the corner area between the horizontal section 101 and the vertical section 102. This design makes the device structure more compact, and the base 1 has a simple structure that is easy to process and manufacture. Of course, in actual use, in order to make the terminal block 5 more stable, corresponding clamps or positioning posts can be provided at the placement station 11.

[0043] To further enhance the flexibility and applicability of the testing, a slotted groove 12 can be provided on the base 1 (i.e., the horizontal section 101). The length of the slotted groove 12 is aligned with the length of the base 1. By fixing the drive device 2 at different positions within the slotted groove 12 with bolts, the installation position can be fine-tuned to accommodate the testing of terminals 5 of different specifications or sizes. This design not only improves the versatility of the device but also greatly enhances its practical value. In operation, the user simply needs to loosen the bolts, move the drive device 2 along the slotted groove 12 to the appropriate position, and then retighten the bolts to adjust the position; the operation is simple and quick.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application.
