Description

Technical Field

[0001] This application relates to the field of measurement technology, and in particular to a measuring device for measuring the resistance and insulation between the pins of an electrical connector. Background Technology

[0002] Electrical connectors are commonly used devices for connecting circuits. They primarily achieve this connection through pins. In practical use, it's necessary to periodically measure the resistance and insulation of each pin to ensure proper functioning. Currently, the measurement method involves connecting the pins to a multimeter and megohmmeter using multiple leads. However, due to the small size of the connector pins and limited operating space, miscounting or incorrect pin connections are easy, and leads can easily detach. Furthermore, the small size of the pins makes them susceptible to bending when pulled or when not perpendicular during connection, leading to connector damage. The leads and pins are connected by clips, which can result in inaccurate measurements due to a weak connection. When measuring insulation, high voltage is applied to the circuit, and the exposed metal of the leads poses a risk of electric shock. Additionally, the entire measurement process is cumbersome and time-consuming. Utility Model Content

[0003] The main objective of this application is to provide a measuring device for the resistance and insulation between the pins of an electrical connector that avoids the above-mentioned drawbacks. Using this measuring device to measure the resistance and insulation between the pins involves fewer steps, provides accurate results, is less likely to damage the electrical connector, and offers high safety.

[0047] Exemplary embodiments will now be described more fully with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in many forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the concept of the exemplary embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and therefore their detailed description will be omitted.

[0048] In the following description of various exemplary embodiments of the present invention, reference is made to the accompanying drawings, which form part of the present invention, and which illustrate by way of example different exemplary structures, systems, and steps that can implement various aspects of the present invention. It should be understood that other specific solutions to components, structures, exemplary devices, systems, and steps may be used, and structural and functional modifications may be made without departing from the scope of the present invention. Furthermore, although the terms “above,” “between,” “within,” etc., may be used in this specification to describe different exemplary features and elements of the present invention, these terms are used herein only for convenience, such as the orientation according to the examples shown in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present invention.

[0049] It is understood that the terms "comprising" and "having," and any variations thereof, in the embodiments of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or components inherent to such processes, methods, products, or devices.

[0050] Relative terms such as “down” or “bottom” and “up” or “top” may be used herein to describe the relationship of one element to another, as illustrated in the figures. It should be understood that relative terms are intended to include different orientations of the device beyond those shown in the figures. For example, if a device in one of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “down” can include both “down” and “up” orientations, and the term “bottom” can include both “bottom” and “top” orientations, depending on the specific orientation of the figure. Similarly, if a device in one of the figures is flipped, an element described as “down” or “bottom” of another element will be oriented “up” or “top” of that element. Thus, the exemplary term “bottom” or “below” can include both “up” and “down” orientations.

[0051] See Figures 1 to 3 The measuring device 100 of this application is mainly used to measure the resistance and insulation between the pins of an electrical connector 200, wherein the electrical connector 200 can be an electrical connector connected to a selector valve of an aircraft landing gear system. The measuring device 100 includes a body 10, multiple switches 20, and multiple sockets 30. In this embodiment, the measuring device 100 is rectangular in shape. The body 10 includes an upper box 101 and a lower box 102. The opposing portions of the upper box 101 and the lower box 102 form cavities. The upper box 101 and the lower box 102 are connected together by four sets of mounting members 107, which are located at the four corners of the body 10. Each set of mounting members 107 may include a bolt, a washer, and a matching nut. The upper box 101 and the lower box 102 have through holes, through which the bolt passes and is fixed by the nut.

[0052] Multiple switches 20 are disposed within the main body 10, with the main structure of each switch 20 housed within a cavity. The parts of the switches 20 requiring operator intervention are exposed on the surface of the upper housing 101 for easy operation. One end of each switch 20 is electrically connected together via a wire 40, and the other end is connected via another wire 40 to corresponding sockets 30. The sockets 30 are used to connect the probes 400 of measuring instruments (see [reference]). Figure 5 This device is used to measure resistance and insulation. One portion of the socket 30 has one end electrically connected to a pin, and the other end connected to a switch 20 via a wire 40. This portion of the socket 30 is primarily used to measure the resistance between the pins. Another portion of the socket 30 has the same electrical connection to a pin; this portion of the socket 30 is primarily used to measure the insulation of the pins.

[0053] The measuring device 100 of this application has multiple switches 20 and multiple sockets 30 on its main body 10. One end of each switch 20 is electrically connected together via a wire 40, and the other end is connected to a socket 30 via a wire 40. Using multiple sockets 30 to connect the probes 400 of the measuring instrument simplifies and speeds up the measurement process. Some sockets 30 are used to measure the resistance between the pins, while others are used to measure the insulation performance of the pins. This allows for easy switching between resistance and insulation measurement using the switches 20, simplifying the measurement process, reducing steps, and saving time. The absence of lead wires during measurement avoids incorrect pin connections and lead wire detachment, improving the accuracy and safety of the measurement results.

[0054] Multiple switches 20 are fixed to the body 10 by multiple switch fasteners 201, and multiple sockets 30 are fixed to the body 10 by multiple socket fasteners 301. Both the switch fasteners 201 and the socket fasteners 301 can be nuts or other types of fasteners. The switches 20 can be toggle switches or other types of switches, as long as they can switch between on and off states. The sockets 30 can be banana plugs; 4mm banana plugs 30 are compatible with the test leads 400 of the measuring instrument, making measurement simpler and more reliable. The measuring instrument used for measuring resistance is a multimeter 300 (see [link]). Figure 4 The measuring instrument used for measuring insulation is a megohmmeter 500 (see [reference]). Figure 6 ).

[0055] In this embodiment, see Figure 2 The pins of the socket 30 and the electrical connector 200 are configured in a one-to-one correspondence. Similarly, the socket 30 connecting to the switch 20 is configured in a one-to-one correspondence with the switch 20. This allows for easy switching between resistance and insulation measurement using the socket 30 in conjunction with the switch 20, reducing measurement steps, significantly decreasing measurement time, and greatly improving measurement efficiency. Furthermore, the measurement does not require lead wires, eliminating exposed metal and improving the accuracy and safety of the measurement results.

[0056] In this embodiment, the measuring device 100 further includes a connecting harness 50 and a connecting connector 60. The connecting connector 60 is electrically connected to the connecting harness 50 and is used to connect to the electrical connector 200. The connecting harness 50 is used to connect to the socket 30. Using the connecting connector 60 to connect to the electrical connector 200 to be measured ensures a reliable, safe, convenient, and efficient connection. The connecting harness 50 electrically connects the connecting connector 60 and the socket 30, improving measurement safety by avoiding exposed wires, preventing exposed metal, and eliminating the risk of electric shock.

[0057] In this embodiment, the main body 10 is provided with a slot 103 for the connecting wire harness 50 to pass through and for fixing the connecting wire harness 50. The slot 103 can fix the connecting wire harness 50 and prevent the connecting wire harness 50 from swinging during use, which could cause poor contact between the connecting wire harness 50 and the socket 30. The slot 103 improves the overall measurement reliability and accuracy of the measuring device 100 and extends the service life of the measuring device 100.

[0058] In this embodiment, the connector 200 has a grounding pin, and the socket 30 without the switch 20 can be electrically connected to the grounding pin. When measuring insulation, the grounding pin needs to be brought out; therefore, the socket 30 without the switch 20 is configured to be electrically connected to the grounding pin for insulation measurement.

[0059] In this embodiment, the numbers of the sockets 30 are the same as the numbers of the pins of the electrical connectors 200. For example, if pin 1 is the grounding pin, then the socket 30 connected to the grounding pin on the measuring device 100 is also numbered 1. The remaining sockets 30 are numbered 4, 5, 7, 8, 9, and 10, respectively.

[0060] In this embodiment, the body 10 has multiple first mounting holes 104 and multiple second mounting holes 105. The first mounting holes 104 are used to mount the socket 30, and the second mounting holes 105 are used to mount the switch 20. Both the first mounting holes 104 and the second mounting holes 105 are formed in the upper housing 101. The socket 30 and the switch 20 are mounted to the body 10 through the first mounting holes 104 and the second mounting holes 105, and are fixed by their respective fasteners. The inner wall of the second mounting hole 105 is provided with a protrusion 106 for limiting the switch 20. The protrusion 106 facilitates the installation of the switch 20 and prevents the switch 20 from rotating.

[0061] See Figure 4 and Figure 5 In this embodiment, when all switches 20 are in the off position, the measuring device 100 can measure the resistance between any two pins of the other pins except the ground pin.

[0062] See Figure 6 and Figure 7 In this embodiment, when all switches 20 are in the ON position, the measuring device 100 can measure whether the grounding pin of the electrical connector 200 is insulated from the other pins.

[0063] The measuring device 100 of this application also has a second embodiment, which is similar to... Figures 1 to 7 Compared to the measuring device 100 of the second embodiment, it has a substantially similar structure in its basic construction. Therefore, in the following description of the measuring device 100 of this second embodiment, the description will not be repeated. Figures 1 to 7 The structure has already been described in the implementation method. Additionally, regarding... Figures 1 to 7 The structures of the measuring device 100 described in the embodiments are the same as those of the original device and are marked with the same reference numerals. Therefore, in the following description of this embodiment, the structures of the same type as those of the original device will be mainly referred to. Figures 1 to 7 The differences between the measuring device 100 in the second embodiment will be explained. In this second embodiment, the measuring device 100 mainly includes a first terminal block, which is electrically connected to a connecting harness 50, and the connecting harness 50 is electrically connected to a socket 30 through the first terminal block.

[0064] In this embodiment, the main body 10 is provided with a second terminal block, which is electrically connected to the socket 30, and the second terminal block can be electrically connected to the first terminal block.

[0065] In the second embodiment, a second terminal is provided on the body 10 of the measuring device 100, and a first terminal is provided at one end of the unconnected connector 60 of the connecting wire harness 50. The connecting wire harness 50 and the socket 30 of the measuring device 100 are electrically connected through the first terminal and the second terminal, which makes the storage and transportation of the measuring device 100 easier.

[0066] The above is a detailed description of several exemplary embodiments of the measuring device 100 proposed in this application. The following will describe in detail the usage process of the measuring device 100 proposed in this application.

[0067] Combined with appendix Figures 1 to 7 The process of using the measuring device 100 proposed in this application is as follows:

[0068] First, the connector 60 is electrically connected to the connector 200. During connection, matching limiting structures can be provided on the connector 200 and the connector 60 to ensure that the pin markings and the socket 30 of the measuring device 100 correspond correctly.

[0069] Then, measure the resistance, see [reference needed]. Figure 4 and Figure 5 Turn on all switches 20 and insert the probes 400 of the multimeter 300 into the corresponding sockets 30, for example, to measure the resistance between labels 4 and 5, between labels 7 and 8, and between labels 10 and 11.

[0070] After the resistance measurement, turn off switch 20 completely. See below. Figure 6 and Figure 7 Thus, pins numbered 4, 5, 7, 8, 9, and 10 are electrically connected together, and the insulation between these pins and pin numbered 1 can be measured using a megohmmeter 500.

[0071] In summary, the measuring device proposed in this application includes a main body, multiple switches, and multiple sockets. Multiple switches are disposed on the main body, with one end of each switch electrically connected together via wires, and the other end remaining free. Multiple sockets are disposed on the main body for connecting the probes of measuring instruments. Some sockets have one end electrically connected to a pin, and the other end connected to the free end of the switch via wires; other sockets have the same functionality. The switching on and off of the switches enables switching between resistance and insulation measurements. No lead wires are required during measurement, avoiding incorrect pin connections or lead wire detachment, thus improving the accuracy and safety of the measurement results. The measurement process is simple, time-efficient, and highly effective.
