Utility Model Content
[0004] The utility model aims to provide an electrical connection monitoring device, which can detect and display the connection status of a wire and a connector to ensure the connection reliability.
[0005] In order to achieve the above-mentioned purpose, a specific embodiment of the utility model provides an electrical connection monitoring device for a connector, including a shell and at least one monitoring component. The shell includes at least one channel group, each channel group includes a cavity and a first channel and a second channel that pass through the shell, the first channel is used for the wire to be connected to pass through, and the second channel is connected to the cavity.

DETAILED DESCRIPTION
[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0030] like Figure 1-7 As shown, an electrical connection monitoring device 100 for a connector in an embodiment of the utility model comprises a housing 10 and a monitoring assembly 20. The housing 10 is formed with at least one channel group, each of which comprises a first channel 11, a second channel 12 and a cavity 13. The first channel 11 is used to insert a wire, and the second channel 12 is connected to the cavity 13. The number of monitoring assemblies 20 is the same as that of the channel groups, and each monitoring assembly 20 comprises a monitoring circuit 21 and a slider 22. The slider 22 is slidably disposed in the second channel 12 and is formed with a protrusion 221 protruding into the cavity 13. The monitoring circuit 21 is fixed in the cavity 13, and comprises an indicator 211 and two guide pieces 212 that are disposed oppositely and in contact, and the contact points of the two guide pieces 212 are located on the travel path of the protrusion 221.
[0031] The electrical connection monitoring device 100 of the connector has two states: on and off. When in the on state, the protrusion 221 is away from the contact point of the two guide plates 212. At this time, the two guide plates 212 are in contact, the monitoring circuit 21 is on, and the indicator 211 gives a prompt; when the slider 22 drives the protrusion 221 to move toward one side of the guide plates 212, the protrusion 221 moves and is squeezed between the guide plates 212. At this time, the two guide plates 212 are not in contact, the monitoring circuit 21 is disconnected, the indicator 211 does not work, and the electrical connection monitoring device 100 of the connector is in the off state.
[0032] The electrical connection monitoring device 100 of the connector in this embodiment can be used to monitor the wire connection status of a connector with a mechanical reset structure (push block). The electrical connection monitoring device 100 of the connector is fixed to the wire insertion end of the connector. When the wire is not inserted, the monitoring circuit 21 is in a conductive state and the indicator 211 works normally. After the wire is inserted into the target connector and correctly connected to the conductor inside the connector, the reset push block moves outward and pushes the slider 22 to move, the protrusion 221 is squeezed between the guide pieces 212, the monitoring circuit 21 is disconnected, and the indicator does not work.
[0033] Specifically, the indicator 211 can be Figure 1 and 5 The indicator light shown in the figure is exposed from the housing 10, or other prompting devices such as a buzzer are used, which is not limited in this embodiment.
[0034] Combination Figure 1 and 2 It can be seen that the first channel 11 adopts a closed design, that is, the inner diameter at the outlet along the wire insertion direction is smaller than the inner diameter at the inlet. Therefore, when connecting a wire whose diameter is larger than the inner diameter of the outlet of the first channel 11 but whose bare wire diameter is smaller than the diameter of the outlet of the first channel 11, only the bare wire can eventually pass through the first channel and be inserted into the connector, while the wire with the insulation layer cannot pass through. This design is used to prevent the insulation layer from entering the connector with the wire, avoiding the situation where the wire cannot be connected normally even if it is inserted into the connector.
[0035] Preferably, the slider 22 is provided with a groove 222 along its length direction, and correspondingly, a stopper 121 extending into the groove 222 is formed on the inner wall of the second channel 12 to prevent the slider 22 from escaping from the second channel 12 .
[0036] Preferably, the stopper 121 is formed at the entrance of the second channel 12, and a reset spring 23 is squeezed between the stopper 121 and the inner wall of the groove 22 near the exit, and two guides 212 are arranged on the entrance side of the wire insertion direction. Therefore, when the slider 22 moves toward the entrance, the protrusion 221 moves and squeezes between the two guides 212, so that the guides 212 are not in contact, and the reset spring 23 is squeezed to store energy; when the slider 22 loses its force, the reset spring 23 releases the stored energy and pushes the slider 22 to move toward the exit, the two guides 212 are in contact again, and the monitoring circuit 21 is turned on again.
[0037] Preferably, a guide column is formed on the stopper 121 and protrudes axially into the return spring 23 to prevent the return spring 23 from shifting.
[0038] like Figure 3 As shown, two relatively arranged slots 131 are formed in the cavity 13, and the two guide pieces 212 respectively include a fixing portion 2121 fixed in the slot 131, and a contact portion 2122 extending from the fixing portion. The contact portions 2122 of the two guide pieces 212 are in contact between the two slots 131, and the two slots 131 are used to fix the guide pieces 212.
[0039] Further, at least one of the two guide pieces 212 is an elastic conductor, which can be elastically deformed when squeezed by the bump 221, and restore contact after the bump 221 moves away. Of course, both guide pieces 212 can also be made of elastic conductors, which is not limited in this embodiment.
[0040] like Figure 2 and 3As shown, the shell 10 has a plug-in portion 14 protruding at the outlet of the first channel 11, and the first channel 11 extends into the plug-in portion 14. The plug-in portion 14 can be inserted into the connector to be wired, so as to fix the electrical connection monitoring device 100 of the connector to the connector to be wired, so as to ensure that the wire can smoothly enter the position of connecting with the conductor in the connector, prevent the wire from sagging due to gravity and causing failure to connect smoothly, and at the same time prevent the two from being abnormally separated during work to affect normal wiring, thereby improving stability.
[0041] Preferably, since the size of the electrical connection monitoring device 100 of the connector is relatively small and the power consumption of the monitoring circuit 21 is relatively low, the electrical connection monitoring device 100 of the connector is powered by a button battery.
[0042] like Figure 8-10 As shown, this embodiment also provides a combined connector, including the above-mentioned connector electrical connection monitoring device 100 and a spring-type connector 200, the spring-type connector 200 includes a wire channel, a reset channel, a push block 201 and a trigger assembly, and a connection space is provided in the spring-type connector 200, and the wire channel and the reset channel are connected to the internal connection space. The wire channel is connected to the first channel 11, and the wire can be inserted into the connection space through the first channel 11 and the wire channel. The reset channel is connected to the second channel 12, and the push block 201 moves in the reset channel, one end of which abuts against the slider 22, and the other end abuts against the trigger assembly. The trigger assembly is fixed in the connection space, including a spring 202 and a retaining spring 203. After the spring 202 undergoes elastic deformation, one end is clamped on the retaining spring 203, and one end of the retaining spring 203 extends to the straight line where the wire channel is located. Therefore, after the wire is inserted, the wire contacts and squeezes the retaining spring 203, the retaining spring 203 is deformed and releases the spring 202, the spring 202 recovers its deformation and pushes the push block 201 to move toward the electrical connection monitoring device 100 of the connector, the push block 201 drives the slider 22 to move toward the entrance of the second channel 12, the protrusion 221 moves and squeezes between the two guide plates 212, the monitoring circuit 21 is disconnected, and the indicator 211 does not work.
[0043] The combined connector has a connected and unconnected state. When the wire 300 is inserted into the spring-type connector 200 through the first channel 11 and the wire channel, it contacts and squeezes the spring clip to deform it. Then the spring clip 202 is separated from the spring clip and pushes the push block 201 to move outward. The push block 201 pushes the slider 22 to move toward the contact end of the guide plate 212. The protrusion 221 is squeezed between the two guide plates 212, the monitoring circuit 21 is disconnected, and the indicator 211 does not work. At this time, the combined connector is in a connected state. When the wire 300 is not correctly connected to the conductor inside the spring-type connector 200, the wire 300 does not correctly contact and squeeze the spring clip 203, resulting in the spring clip 202 not being separated from the spring clip 203, the push block 201 not pushing the slider 22 to move, the guide plate 212 is in normal contact, the monitoring circuit 21 is turned on, and the indicator 211 works and prompts that the wire is not connected normally. At this time, it is in an unconnected state.
[0044] Therefore, when using the combined connector, the staff can intuitively determine whether the wires are correctly connected through the connector's electrical connection monitoring device 100 without having to determine through the connector's side window, thereby improving safety while also improving overall ease of use.
[0045] Preferably, the combined connector has a reset function. The slider 22 is pushed along the second channel 12 toward the side of the spring-type connector 200, and the push block 201 follows and drives the spring 202 to re-engage the retaining spring 203. After the wire is pulled out, the combined connector re-enters the waiting-to-connect state, the monitoring circuit 21 is turned on again, and the indicator 211 works again and prompts that the wire is not connected.
[0046] In one embodiment, the electrical connection monitoring device 100 and the spring-type connector 200 are designed to be detachably connected. Of course, the two can also be integrally formed, which is not limited in this embodiment.
[0047] In this embodiment, when the wire 300 is not inserted or not inserted in place, the monitoring circuit 21 is in a conducting state, and the indicator 211 works normally, and this state is the initial state; when the wire 300 is inserted in place, the monitoring circuit 21 is disconnected, and the indicator 211 does not work. It is conceivable that the contact point of the guide piece 212 can be set on a side close to the spring-type connector 200, and the monitoring mode is adjusted at this time, and the initial state is adjusted to the monitoring circuit 21 disconnected state, at which time the wire 300 is not inserted or the insertion does not trigger the spring piece 202, and the indicator 211 does not work; only when the wire 300 is inserted in place and the spring piece 202 is triggered, the monitoring circuit 21 enters the conducting state, and the indicator 211 starts to work.
