Description

Technical Field

[0001] This utility model relates to the field of connector technology, and more specifically to a connector and industrial equipment. Background Technology

[0002] In related technologies, industrial fields such as industrial robots, logistics and transportation systems, rail transportation, and process automation production lines, due to the negligence of debugging, maintenance, or operation workers, live connectors may be directly unplugged, causing live plugs to be exposed to spaces that people may come into contact with, posing a risk of personal injury. Utility Model Content

[0003] The present invention aims to at least solve or improve the technical problem in the related art that after the connector is disconnected while it is energized, the plug connected to the power supply remains energized, which increases the safety risk.

[0004] Therefore, a connector is proposed in the first aspect of this utility model.

[0005] A second aspect of this utility model provides an industrial device.

[0006] In view of the above, according to a first aspect of the present invention, the present invention provides a connector comprising: a first plug, the first plug including a switch assembly and a first circuit assembly, the switch assembly being connected to the first circuit assembly, the switch assembly being normally open; and a second plug, the second plug including a switch trigger assembly and a second circuit assembly; wherein, when the second plug is inserted into the first plug, the first circuit assembly and the second circuit assembly are electrically connected, and the switch trigger assembly and the switch assembly are electrically connected, causing the switch assembly to close.

[0007] The connector proposed in this utility model includes a first plug and a second plug, which can be plugged in and separated. The first plug includes a first circuit assembly, and the second plug includes a second circuit assembly. When the first plug and the second plug are plugged in together, the first circuit assembly and the second circuit assembly are electrically connected, thereby realizing the transmission of signals or energy.

[0008] The first plug also includes a switch assembly connected to the first circuit assembly. The switch assembly is normally open. The second plug also includes a switch trigger assembly, which is used to trigger the switch assembly. When the second plug is plugged into the first plug, the switch trigger assembly triggers the switch assembly, causing the switch assembly to close and the first circuit assembly to conduct, so that a signal or energy can be output to the second circuit assembly.

[0009] Specifically, during use, the first plug is connected to the power supply. Due to the setting of the switch assembly, when the second plug is not plugged into the first plug, the switch assembly is turned off, and the power supply will not supply power to the first circuit assembly. Thus, the first circuit assembly of the first plug is not energized when the second plug is not plugged in, thereby improving the safety of the connector and reducing the risk of electric shock to personnel.

[0010] In some technical solutions, optionally, the first plug further includes a first main line and a second main line; the switch assembly includes: an electronically controlled switch, which includes a first electronically controlled terminal, a second electronically controlled terminal, and a switch part, wherein the first electronically controlled terminal is electrically connected to the first main line, and the switch part is connected to a first circuit assembly; a first pin, which is electrically connected to the second electronically controlled terminal; and a second pin, which is electrically connected to the second main line; wherein, when the second plug is inserted into the first plug, the switch trigger assembly conducts the first pin and the second pin.

[0011] In this technical solution, the first plug also includes a first main wire and a second main wire, wherein the first main wire can be connected to the positive terminal or live wire of the power supply, and the second main wire can be connected to the negative terminal or neutral wire of the power supply.

[0012] The switch assembly includes an electric control switch, a first pin, and a second pin. The electric control switch is electrically connected to a first main line, the first pin is electrically connected to the electric control switch, and the second pin is electrically connected to the second main line.

[0013] The electronically controlled switch includes a first electronically controlled terminal, a second electronically controlled terminal, and a switching part. The switching part is connected to the first circuit assembly. The switching part is normally open, meaning that the switching part is open when the electronically controlled switch is not triggered.

[0014] The first control terminal of the electric switch is electrically connected to the first main line, and the second control terminal is electrically connected to the first pin. When the second plug is not inserted into the first plug, the first and second control terminals cannot form a circuit, the switch is open, the first circuit assembly and the first main line are in an open-circuit state, the first circuit assembly is not energized, and the first and second pins are also not energized, thus improving safety. When the second plug is inserted into the first plug, the switch trigger component conducts the first and second pins, the first and second control terminals form a circuit, the switch is closed, the first circuit assembly and the first main line are in a conductive state, the first circuit assembly is energized, and transmits signals or energy to the second circuit assembly, thereby outputting signals or energy to the electrical equipment.

[0015] Furthermore, the switch assembly has a simple structure and is easy to manufacture.

[0016] In some technical solutions, optionally, the switch triggering component includes: a third pin; a fourth pin, and the third pin being electrically connected; wherein, when the second plug is inserted into the first plug, the first pin and the third pin are in contact, and the second pin and the fourth pin are in contact.

[0017] In this technical solution, the switch triggering component includes a third pin and a fourth pin, which are electrically connected. When the second plug is inserted into the first plug, the first pin and the third pin are in contact, and the second pin and the fourth pin are in contact, so that the first main line, the first electronic control terminal, the second electronic control terminal, the first pin, the third pin, the fourth pin, the second pin, and the second main line are connected in sequence to form a circuit, triggering the electronic control switch, causing the switch to close, and the first circuit component and the first main line are electrically connected, thereby transmitting signals or energy to the second plug.

[0018] The switch trigger component has a simple structure and is compatible with the plug-in method of the first and second plugs.

[0019] In some technical solutions, the electronically controlled switch may optionally be a relay.

[0020] In this technical solution, the electronic control switch is a relay. Relays have a high switching count, higher durability, and longer service life. Furthermore, the indicator light on the relay allows personnel to visually determine whether the first circuit component is energized, reducing the possibility of electric shock.

[0021] In some technical solutions, optionally, the switch part includes a first end and a second end, the first end being electrically connected to a first main line; the first circuit assembly includes: a fifth pin, electrically connected to the second end, the first end of the switch part being electrically connected to the first main line; a sixth pin, the sixth pin being electrically connected to the second main line; the second circuit assembly includes a seventh pin and an eighth pin; wherein, when the second plug is inserted into the first plug, the fifth pin and the seventh pin are in contact, and the sixth pin and the eighth pin are in contact.

[0022] In this technical solution, the switch part includes a first end and a second end, and the first circuit assembly includes a fifth pin and a sixth pin. The first end of the switch part is electrically connected to the first main line, the second end of the switch part is electrically connected to the fifth pin, and the sixth pin is electrically connected to the second main line. Thus, when the switch part is open, the fifth pin and the first main line are in an open circuit state, and when the switch part is closed, the fifth pin and the first main line are in a conductive state.

[0023] The second circuit assembly includes a seventh pin and an eighth pin. When the second plug is inserted into the first plug, the fifth pin and the seventh pin are in contact, the sixth pin and the eighth pin are in contact, and the switch is closed, allowing the first plug to transmit signals or energy to the second plug.

[0024] The first and second circuit components have simple structures and are easy to manufacture.

[0025] In some technical solutions, the fifth and sixth pins may optionally protrude from the first and second pins.

[0026] In this technical solution, the fifth and sixth pins protrude from the first and second pins. As a result, when the second plug is pulled out of the first plug, the first and second pins will detach from the second plug first. Thus, before the fifth and sixth pins detach from the second plug, the fifth pin is disconnected from the first main line, thereby further reducing the risk of electric shock to personnel.

[0027] Furthermore, during the process of unplugging the second plug from the first plug, the first pin will detach from the third pin first, and the second pin will detach from the fourth pin first. Then, if the fifth and seventh pins, and the sixth and eighth pins are not detached, the fifth pin will be disconnected from the first main line, reducing the possibility of arcing when the fifth pin detaches from the seventh pin and improving the safety of the connector.

[0028] In some technical solutions, the second circuit component may optionally protrude from the switch trigger component.

[0029] In this technical solution, the second circuit component protrudes from the switch trigger component. As the second plug is pulled out of the first plug, the switch trigger component will disengage from the second plug first. Thus, before the second circuit component disengages from the second plug, the first circuit component is disconnected from the first main line, thereby further reducing the risk of electric shock to personnel.

[0030] Furthermore, during the process of the switch trigger component pulling out the first plug, the switch trigger component will first detach from the switch component. Then, even if the second circuit component and the first circuit component are not detached, the first circuit component will be disconnected from the first main line, reducing the possibility of arcing when the first circuit component detaches from the second circuit component and improving the safety of the connector.

[0031] In some technical solutions, the first plug may optionally include: a first ferrule, a switch assembly and a first circuit assembly fixed to the first ferrule; and a first housing located outside the first ferrule. The second plug may also include: a second ferrule, a switch trigger assembly and a second circuit assembly fixed to the second ferrule; and a second housing located outside the second ferrule.

[0032] In this technical solution, the first plug also includes a first ferrule and a first housing. The first ferrule is disposed on the outside of the switch assembly and the first circuit assembly to fix the switch assembly and the first circuit assembly. The first housing is disposed on the outside of the first ferrule and serves to protect personnel, the ferrule, the switch circuit and the first circuit assembly, thereby improving the reliability and safety of the connector.

[0033] The second plug also includes a second ferrule and a second housing. The second ferrule is located outside the switch trigger assembly and the second circuit assembly to fix the switch trigger assembly and the second circuit assembly. The second housing is located outside the second ferrule and serves to protect personnel, the ferrule, the switch trigger assembly and the second circuit assembly, thereby improving the reliability and safety of the connector.

[0034] In some technical solutions, the first plug may be a female plug and the second plug may be a male plug.

[0035] In this technical solution, the first plug is a female plug and the second plug is a male plug, which improves the safety of the connector.

[0036] According to a second aspect of the present invention, an industrial device is provided, comprising: a device body; and a connector as provided in the first aspect embodiment.

[0037] The industrial equipment proposed in this utility model includes the connector provided in the first aspect embodiment, and therefore has all the beneficial effects of the connector provided in the first aspect embodiment, which will not be described in detail here.

[0053] like Figure 1 , Figure 2 and Figure 3 As shown, according to a first aspect of the present invention, the present invention provides a connector 1, which can be used to transmit signals or energy. To illustrate, the connector 1 is used to transmit energy. The connector 1 can connect an AC power source to the main body of the device that uses electricity, or it can connect a DC power source to the main body of the device that uses electricity.

[0054] Connector 1 includes a first plug 11 and a second plug 13, which can be plugged together or separated and independent of each other.

[0055] The first plug 11 includes a switch assembly 111 and a first circuit assembly 120. The switch assembly 111 is connected to the first circuit assembly 120. The switch assembly 111 is normally open, that is, the switch assembly 111 is disconnected when it does not receive a control signal.

[0056] The second plug 13 includes a switch trigger component 131 and a second circuit component 134. The switch trigger component 131 is matched with the switch component 111, and the second circuit component 134 is matched with the first circuit component 120. The switch trigger component 131 is used to trigger the switch component 111, causing the switch component 111 to close.

[0057] When the first plug 11 and the second plug 13 are separated and independent of each other, the switch assembly 111 is disconnected and the first circuit assembly 120 is disconnected and not energized. When the second plug 13 is plugged into the first plug 11, the first circuit assembly 120 and the second circuit assembly 134 are electrically connected, and the switch trigger assembly 131 is electrically connected to the switch assembly 111, causing the switch assembly 111 to close. The first circuit assembly 120 becomes conductive, transmitting signals or energy to the second circuit assembly 134, and then to the main body of the device.

[0058] The connector 1 proposed in this utility model includes a first plug 11 and a second plug 13. The first plug 11 and the second plug 13 can be plugged in and separated. The first plug 11 includes a first circuit component 120, and the second plug 13 includes a second circuit component 134. When the first plug 11 and the second plug 13 are plugged in together, the first circuit component 120 and the second circuit component 134 are electrically connected, thereby realizing the transmission of signals or energy.

[0059] The first plug 11 also includes a switch assembly 111, which is connected to the first circuit assembly 120. The switch assembly 111 is normally open. The second plug 13 also includes a switch trigger assembly 131, which is used to trigger the switch assembly 111. When the second plug 13 is plugged into the first plug 11, the switch trigger assembly 131 triggers the switch assembly 111, causing the switch assembly 111 to close, thereby turning on the first circuit assembly 120 and allowing signals or energy to be output to the second circuit assembly 134.

[0060] For example, in use, the first plug 11 is connected to the power supply. Due to the setting of the switch assembly 111, when the second plug 13 is not plugged into the first plug 11, the switch assembly 111 is turned off, and the power supply will not supply power to the first circuit assembly 120. The second plug 13 is connected to the main body of the device. Thus, the first circuit assembly 120 of the first plug 11 is not energized when the second plug 13 is not plugged into it, thereby improving the safety of the connector 1 and reducing the risk of electric shock to personnel.

[0061] like Figure 2 , Figure 4 and Figure 5 As shown, in some embodiments, the first plug 11 may optionally include a first main wire 125 and a second main wire 126, wherein the first main wire 125 is used to connect the live wire and the second main wire 126 is used to connect the neutral wire, or the first main wire 125 is used to connect the positive terminal and the second main wire 126 is used to connect the negative terminal.

[0062] The switch assembly 111 includes an electric control switch 112, a first pin 118 and a second pin 119. The electric control switch 112 is electrically connected to a first main line 125, the first pin 118 is electrically connected to the electric control switch 112, and the second pin 119 is electrically connected to the second main line 126.

[0063] The electric control switch 112 includes a first electric control terminal 113, a second electric control terminal 114, and a switch part 115. The switch part 115 can be turned off or on. The first electric control terminal 113 is electrically connected to the first main line 125. The switch part 115 is connected to the first circuit assembly 120. The first pin 118 is electrically connected to the second electric control terminal 114. The second pin 119 is electrically connected to the second main line 126.

[0064] When the first plug 11 and the second plug 13 are separated and independent of each other, the first electrical control terminal 113, the second electrical control terminal 114, the first main line 125 and the second main line 126 will not form a circuit, the switch 115 is disconnected, there is no electrical connection between the first circuit assembly 120 and the first main line 125, and the first circuit assembly 120 is not energized.

[0065] When the second plug 13 is plugged into the first plug 11, the switch trigger assembly 131 conducts the first pin 118 and the second pin 119. The first electronic control terminal 113, the second electronic control terminal 114, the first main line 125 and the second main line 126 form a circuit. The switch part 115 is closed, and the first circuit assembly 120 and the first main line 125 are electrically connected. The first circuit assembly 120 is energized and transmits energy to the second circuit assembly 134.

[0066] In this embodiment, the first plug 11 further includes a first main line 125 and a second main line 126, wherein the first main line 125 can be connected to the positive terminal or live wire of the power supply, and the second main line 126 can be connected to the negative terminal or neutral wire of the power supply.

[0067] The switch assembly 111 includes an electric control switch 112, a first pin 118 and a second pin 119. The electric control switch 112 is electrically connected to a first main line 125, the first pin 118 is electrically connected to the electric control switch 112, and the second pin 119 is electrically connected to the second main line 126.

[0068] The electronic control switch 112 includes a first electronic control terminal 113, a second electronic control terminal 114, and a switch part 115. The switch part 115 is connected to the first circuit assembly 120. The switch part 115 is normally open, that is, the switch part 115 is open when the electronic control switch 112 is not triggered.

[0069] The first control terminal 113 of the electric switch 112 is electrically connected to the first main line 125, and the second control terminal 114 of the electric switch 112 is electrically connected to the first pin 118. When the second plug 13 is not plugged into the first plug 11, the first control terminal 113 and the second control terminal 114 cannot form a circuit, the switch part 115 is open, the first circuit assembly 120 and the first main line 125 are in an open circuit state, the first circuit assembly 120 is not energized, and the first pin 118 and the second pin 119 are also not energized, thus improving safety. When the second plug 13 is plugged into the first plug 11, the switch trigger assembly 131 conducts the first pin 118 and the second pin 119, the first control terminal 113 and the second control terminal 114 form a circuit, the switch part 115 is closed, the first circuit assembly 120 and the first main line 125 are in a conducting state, the first circuit assembly 120 is energized, and transmits signals or energy to the second circuit assembly 134, thereby outputting signals or energy to the electrical equipment.

[0070] Furthermore, the switch assembly 111 has a simple structure and is easy to manufacture.

[0071] The number of first pins 118 can be one or more. The number of second pins 119 can be one or more.

[0072] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, the first plug 11 may optionally include a third main line 127 for grounding. The first plug 11 also includes a protective layer 128 disposed outside the first main line 125, the second main line 126 and the third main line 127, and the protective layer 128, the first main line 125, the second main line 126 and the third main line 127 may form a cable.

[0073] like Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, optionally, the switch triggering component 131 includes a third pin 132 and a fourth pin 133, which are electrically connected. When the second plug 13 is plugged into the first plug 11, the first pin 118 and the third pin 132 are in contact, and the second pin 119 and the fourth pin 133 are in contact. Thus, the first main line 125, the first electronic control terminal 113, the second electronic control terminal 114, the first pin 118, the third pin 132, the fourth pin 133, the second pin 119, and the second main line 126 form a circuit. The electronic switch 112 is triggered, the switch part 115 is closed, and the first circuit component 120 is turned on.

[0074] In this embodiment, the switch trigger assembly 131 includes a third pin 132 hook and a fourth pin 133, and the third pin 132 and the fourth pin 133 are electrically connected. When the second plug 13 is plugged into the first plug 11, the first pin 118 and the third pin 132 are in contact, and the second pin 119 and the fourth pin 133 are in contact, so that the first main line 125, the first electronic control terminal 113, the second electronic control terminal 114, the first pin 118, the third pin 132, the fourth pin 133, the second pin 119 and the second main line 126 are connected in sequence to form a circuit, triggering the electronic control switch 112, so that the switch part 115 is closed, and the first circuit assembly 120 and the first main line 125 are electrically connected, thereby transmitting signals or energy to the second plug 13.

[0075] The switch trigger component 131 has a simple structure and is compatible with the plug-in method of the first plug 11 and the second plug 13.

[0076] The third pin 132 and the fourth pin 133 can be an integral structure to achieve electrical connection, or they can be electrically connected through wires.

[0077] The number of third pins 132 can be one or more. The number of fourth pins 133 can be one or more.

[0078] like Figure 4 and Figure 5 As shown, in some embodiments, the electronically controlled switch 112 may optionally be a relay.

[0079] In this embodiment, the electronic switch 112 is a relay. Relays have a high switching count, higher durability, and longer service life. Furthermore, the indicator light on the relay allows personnel to visually determine whether the first circuit component 120 is energized, reducing the possibility of electric shock.

[0080] Microswitches can also control power on and off, but they have a low effective lifespan and long-term compression can cause the metal of the microswitch spring to deform and fail, making it impossible to disconnect the connector 1 after it is pulled out. Furthermore, it is not visually identifiable whether the microswitch is working. The connector 1 provided by this utility model uses a relay, which relies on the coil to control power on and off. It not only has a high number of switching cycles and is more durable, but the coil indicator light allows users to visually determine whether the contacts are energized, thereby avoiding electric shock.

[0081] Furthermore, a relay is a reliable electrical component that does not require a built-in chip, thus perfectly avoiding problems caused by chip interference leading to malfunctions.

[0082] The first control terminal 113 and the second control terminal 114 are the two contacts of the relay coil, respectively.

[0083] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the switch portion 115 includes a first end 116 and a second end 117. The first end 116 is electrically connected to the first main line 125. The first circuit assembly 120 includes a fifth pin 121 and a sixth pin 122. The fifth pin 121 is electrically connected to the second end 117 of the switch portion 115, and the sixth pin 122 is electrically connected to the second main line 126. That is, the switch portion 115 is connected between the fifth pin 121 and the first main line 125.

[0084] The second circuit assembly 134 includes a seventh pin 135 and an eighth pin 136. When the second plug 13 is plugged into the first plug 11, the fifth pin 121 and the seventh pin 135 are in contact, and the sixth pin 122 and the eighth pin 136 are in contact.

[0085] In this embodiment, the switch portion 115 includes a first end 116 and a second end 117, and the first circuit assembly 120 includes a fifth pin 121 and a sixth pin 122. The first end 116 of the switch portion 115 is electrically connected to the first main line 125, the second end 117 of the switch portion 115 is electrically connected to the fifth pin 121, and the sixth pin 122 is electrically connected to the second main line 126. Thus, when the switch portion 115 is open, the fifth pin 121 and the first main line 125 are in an open circuit state, and when the switch portion 115 is closed, the fifth pin 121 and the first main line 125 are in a conductive state.

[0086] The second circuit assembly 134 includes a seventh pin 135 and an eighth pin 136. When the second plug 13 is plugged into the first plug 11, the fifth pin 121 and the seventh pin 135 are in contact, the sixth pin 122 and the eighth pin 136 are in contact, and the switch 115 is closed, so that the first plug 11 can transmit signals or energy to the second plug 13.

[0087] The first circuit assembly 120 and the second circuit assembly 134 have simple structures and are easy to manufacture.

[0088] The number of fifth pins 121 can be one or more. The number of sixth pins 122 can be one or more. The number of seventh pins 135 can be one or more. The number of eighth pins 136 can be one or more. For example, the number of fifth pins 121, sixth pins 122, seventh pins 135 and eighth pins 136 can all be 1, 2, 3, 4, 5, 6, 7 or 8.

[0089] Terminal 116 and terminal 117 are the two normally open contacts of the relay.

[0090] like Figure 1 and Figure 2 As shown, in some embodiments, optionally, the fifth pin 121 and the sixth pin 122 protrude from the first pin 118 and the second pin 119.

[0091] In this embodiment, the fifth pin 121 and the sixth pin 122 protrude from the first pin 118 and the second pin 119. As a result, during the process of the second plug 13 being pulled out of the first plug 11, the first pin 118 and the second pin 119 will disengage from the second plug 13 first. Thus, when the fifth pin 121 and the sixth pin 122 have not disengaged from the second plug 13, the fifth pin 121 is disconnected from the first main line 125, thereby further reducing the risk of electric shock to personnel.

[0092] Furthermore, during the process of the second plug 13 being pulled out of the first plug 11, the first pin 118 will first detach from the third pin 132, and the second pin 119 will first detach from the fourth pin 133. Thus, if the fifth pin 121 and the seventh pin 135 are not detached, and the sixth pin 122 and the eighth pin 136 are not detached, the fifth pin 121 will be disconnected from the first main line 125, reducing the possibility of arcing when the fifth pin 121 detaches from the seventh pin 135 and improving the safety of the connector 1.

[0093] That is, the lengths of the fifth pin 121 and the sixth pin 122 are greater than the lengths of the first pin 118 and the second pin 119.

[0094] For example, the third pin 132, the fourth pin 133, the seventh pin 135, and the eighth pin 136 are flush. Or the seventh pin 135 and the eighth pin protrude from the third pin 132 and the fourth pin 133.

[0095] like Figure 1 and Figure 3 As shown, in some embodiments, optionally, the second circuit component 134 protrudes from the switch trigger component 131.

[0096] In this embodiment, the second circuit component 134 protrudes from the switch trigger component 131. As the second plug 13 is pulled out of the first plug 11, the switch trigger component 131 will disengage from the second plug 13 first. Thus, when the second circuit component 134 has not disengaged from the second plug 13, the first circuit component 120 is disconnected from the first main line 125, thereby further reducing the risk of electric shock to personnel.

[0097] Furthermore, during the process of the switch trigger component 131 pulling out the first plug 11, the switch trigger component 131 will first detach from the switch component 111. Then, even if the second circuit component 134 and the first circuit component 120 are not detached, the first circuit component 120 will be disconnected from the first main line 125, reducing the possibility of arcing when the first circuit component 120 detaches from the second circuit component 134 and improving the safety of the connector 1.

[0098] For example, the seventh pin 135 and the eighth pin protrude beyond the third pin 132 and the fourth pin 133. That is, the length of the seventh pin 135 and the eighth pin is greater than the length of the third pin 132 and the fourth pin 133.

[0099] The first pin 118, the second pin 119, the fifth pin 121, and the sixth pin 122 are flush. Alternatively, the fifth pin 121 and the sixth pin 122 protrude from the first pin 118 and the second pin 119.

[0100] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the first plug 11 may optionally include a first insert 123 and a first housing 124. The first insert 123 serves as a fixing base for the switch assembly 111 and the first circuit assembly 120. The switch assembly 111 and the first circuit assembly 120 are fixed in the first insert 123 in a certain order. The first housing 124 is disposed on the outside of the switch assembly 111 and the first insert 123, thereby protecting the switch assembly 111 and the first circuit assembly 120 and providing electromagnetic shielding, insulation and other functions.

[0101] The second plug 13 also includes a second ferrule 137 and a second housing 138. The second ferrule 137 serves as a fixing base for the switch trigger assembly 131 and the second circuit assembly 134. The switch trigger assembly 131 and the second circuit assembly 134 are fixed in the second ferrule 137 in a certain order. The second housing 138 is disposed on the outside of the second ferrule 137, thereby protecting the switch trigger assembly 131 and the second circuit assembly 134, and providing electromagnetic shielding, insulation and other functions.

[0102] In this embodiment, the first plug 11 further includes a first ferrule 123 and a first housing 124. The first ferrule 123 is disposed outside the switch assembly 111 and the first circuit assembly 120 to fix the switch assembly 111 and the first circuit assembly 120. The first housing 124 is disposed outside the first ferrule 123 and serves to protect personnel, the ferrule, the switch circuit and the first circuit assembly 120, thereby improving the reliability and safety of the connector 1.

[0103] The second plug 13 also includes a second ferrule 137 and a second housing 138. The second ferrule 137 is disposed outside the switch trigger assembly 131 and the second circuit assembly 134 to fix the switch trigger assembly 131 and the second circuit assembly 134. The second housing 138 is disposed outside the second ferrule 137 and serves to protect personnel, the ferrule, the switch trigger assembly 131 and the second circuit assembly 134, thereby improving the reliability and safety of the connector 1.

[0104] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, optionally, the first plug 11 is a female plug and the second plug 13 is a male plug.

[0105] In this embodiment, the first plug 11 is a female plug and the second plug 13 is a male plug, which improves the safety of the connector 1.

[0106] The connector 1 provided by this utility model provides the power to engage the relay coil through the first main line 125 and the second main line 126 within the connector 1. Two of the pins in the first plug 11 and the second plug 13 provide a circuit for the relay coil. When the first plug 11 and the second plug 13 are fully inserted, the relay coil is successfully engaged, all normally open contacts are closed, and the downstream equipment receives power. When the first plug 11 and the second plug 13 are pulled out, the shorter relay coil circuit pin will disengage first, the coil is de-energized, the normally open contacts open, and all power supply pins lose power. This prevents the generation of an electric arc when the power supply pins are pulled out, further preventing personal injury to the operator.

[0107] The connection provided in this embodiment of the utility model relies on electrical logic constructed using relays to control the power supply circuits to switch on and off.

[0108] like Figure 4 As shown, under AC power supply (such as 220VAC 50Hz power frequency), when the first main line 125 and the second main line 126 are energized, the coil of the relay cannot be energized because the coil circuit has not yet formed a complete circuit.

[0109] Furthermore, since all switches driven by the coil are normally open contacts (NO), all power supply pins are de-energized when the coil is not engaged. When connector 1 is plugged in, the coil circuit of the relay is short-circuited because the contact side with the coil pin of the relay is short-circuited. The coil is energized and engaged, the normally open contacts close, and all power supply pins are energized.

[0110] like Figure 5 As shown, under DC power supply (e.g., 24VDC), when the first main line 125 and the second main line 126 are energized, the coil of the relay cannot be energized because the coil circuit has not yet formed a complete circuit.

[0111] Furthermore, since all switches driven by the coil are normally open contacts (NO), all power supply pins are de-energized when the coil is not engaged. When connector 1 is plugged in, the coil circuit of the relay is short-circuited because the contact side with the coil pin of the relay is short-circuited. The coil is energized and engaged, the normally open contacts close, and all power supply pins are energized.

[0112] like Figure 2 , Figure 4 and Figure 5 As shown, the first plug 11 includes a first connector 123, a switch assembly 111, a first circuit assembly 120, a first housing 124, and a cable. The shorter first pin 118 and second pin 119 are connected to the relay coil via wires, while the longer fifth pin 121 and sixth pin 122 are connected to one side of the switch contacts of the relay module. The other side of the switch contacts is connected to the first main line 125. These pins are inserted into the first connector 123. The first housing 124 is an EMC housing.

[0113] The line consists of a first main line 125, a second main line 126, a third main line 127, and a protective layer 128.

[0114] like Figure 3 , Figure 4 and Figure 5As shown, the second plug 13 includes a second pin 137, a switch trigger assembly 131, a second circuit assembly 134, and a second housing 138. The shorter third pin 132 and fourth pin 133 are shorted together by a wire, while the longer seventh pin 135 and eighth pin 136 are connected to the device body.

[0115] When the first plug 11 and the second plug 13 are inserted, the longer pins 121 (fifth), 122 (sixth), 135 (seventh), and 136 will make contact first. Only after the first pin 118 (first), 119 (second), 132 (third), and 133 (fourth) make contact will the relay coil engage, the switch close, the contacts be energized, and current be supplied to the power module. Conversely, when the first plug 11 and the second plug 13 are disconnected while energized, the shorter pins 118 (first), 119 (second), 132 (third), and 133 (fourth) will disengage first. After the relay coil loses power, the switch opens. Before the fifth pin 121 (sixth), 122 (seventh), 135 (seventh), and 136 (eighth) disengage, the pins are no longer energized, ensuring the safety of personnel and equipment during power outages.
