The contactor can protect a circuit connected with the contactor, and the circuit breaker can protect the circuit connected with the circuit breaker. When in actual use, the contactor and the breaker can be matched for use and are connected in the same circuit together so as to further ensure the safety of the circuit. In the prior art, the electrical connection between the contactor and the circuit breaker is achieved by providing a connector.

The connector is typically disposed between the contactor and the circuit breaker. Specifically, the connector generally includes a housing and a main electrical conductor extending through the housing. One end of the main electric conduction piece is electrically connected with the contactor, and the other end of the main electric conduction piece is electrically connected with the circuit breaker, so that the electric connection between the contactor and the circuit breaker is realized, and the contactor and the circuit breaker can be matched for use to provide safety guarantee for a circuit. The power supply line may be directly electrically connected to the coil connection port of the contactor to supply electric power to the coil of the contactor, so that the contactor may be in an operating state, and the control circuit is turned on or off.

However, based on the structure of the existing connector, the circuit breaker or the connector may shield the coil wiring port of the contactor, so that the power supply line is not easily electrically connected with the coil wiring terminal. Further, the power supply line is electrically connected directly to the coil terminal of the contactor, and the power supply line is relatively easily separated from the coil terminal, which results in a problem that the connection between the power supply line and the coil terminal is unreliable.

Based on this, the embodiment of the application discloses a connector and a switch assembly.

In order to better understand the embodiments of the present application, the connector and the switch assembly in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

Embodiments of the present application disclose a switch assembly (related figures not provided) that includes a contactor, a circuit breaker, and a connector. The connector is used for connecting the contactor and the circuit breaker, and realizes the electric connection of the circuit breaker and the contactor.

The contactor comprises a contactor wire inlet end, a contactor wire outlet end, an electromagnetic structure and a contact structure, wherein the electromagnetic structure and the contact structure are connected between the contactor wire inlet end and the contactor wire outlet end.

The electromagnetic structure comprises a coil and a static iron core, and the static iron core penetrates through the coil. The contact structure comprises a movable contact and a stationary contact. When the contactor is electrified, current passes through the coil, the current flowing through the coil generates a magnetic field, and the magnetic field force of the magnetic field drives the contact structure of the contactor to act, so that the movable contact is contacted with the stationary contact, and a circuit protected by the contactor is in a connection state. When the coil is powered off, the magnetic field disappears, the contact structure is restored, and the movable contact is separated from the stationary contact, so that a circuit protected by the contactor is in an open state.

The circuit breaker comprises a circuit breaker wire inlet end, a circuit breaker wire outlet end, an operating mechanism and a contact mechanism, wherein the operating mechanism and the contact mechanism are positioned between the circuit breaker wire outlet end and the circuit breaker wire inlet end. When the circuit is in an abnormal state, the operating mechanism can drive the contact mechanism to act, so that a fixed contact and a movable contact in the contact mechanism are separated, and then the circuit breaker is in an open state, and the circuit protected by the circuit breaker is protected.

Any one of the contactor and the circuit breaker is in an open state, so that the circuit protected by the switch assembly is in an open state, and the circuit protected by the switch assembly is protected.

In actual use, the outgoing line end of the circuit breaker may be electrically connected to the incoming line end of the contactor through the connector, or the outgoing line end of the contactor may be connected to the incoming line end of the circuit breaker through the connector, which is not particularly limited in the embodiment of the present application.

The connector disclosed by the application is positioned between the circuit breaker and the contactor, so that the electrical connection between the circuit breaker and the contactor is realized. One or more connectors may be provided between the circuit breaker and the contactor, and other electronic components may be connected between the connectors, which is not limited in this embodiment of the present application. The details of the specific structure of the connector are described below and will not be described here.

Next, the connector mentioned in the above-mentioned switch assembly will be specifically explained. For convenience of description, the present embodiment will be described by taking the connector connecting the outlet terminal of the contactor and the inlet terminal of the circuit breaker as examples.

The connector is positioned between the contactor and the circuit breaker and is used for realizing the electric connection between the contactor and the circuit breaker. Fig. 1 is a schematic structural diagram of a first view of a connector provided in an embodiment of the present application, fig. 2 is a schematic structural diagram of a second view of a connector provided in an embodiment of the present application, fig. 3 is a schematic partial explosion structure of a connector provided in an embodiment of the present application, and referring to fig. 1, fig. 2 and fig. 3, the connector 100 includes a housing 110, a main electrical conductor 120, an auxiliary electrical conductor 140 and a connection terminal 130. Wherein the housing 110 is provided at one side of the contactor. The auxiliary electric conductor 140 is mounted to the housing 110, a first end of the auxiliary electric conductor 140 is electrically connected to the coil terminal of the contactor, and a second end of the auxiliary electric conductor 140 protrudes along the housing 110 toward the connection terminal 130. The binding post 130 includes wiring piece 132, first clamp piece 133 and second clamp piece 131, and first clamp piece 133 is fixed to be overlapped and is established in the first end of wiring piece 132, is equipped with the through-hole on the second clamp piece 131, and the second clamp piece 131 is established in the second end of wiring piece 132 through the movable cover of through-hole, and first clamp piece 133 activity is established in the first end of wiring piece 132 in keeping away from to the second end of auxiliary electric conduction piece 140, and the tip of power supply line is located between the second end of auxiliary electric conduction piece 140 and the first clamp piece 133.

Fig. 4 is a schematic diagram illustrating connection between the first pressing member, the second pressing member, the wire connecting member and the auxiliary electric conduction member in the first state provided in the embodiment of the present application, and fig. 5 is a schematic diagram illustrating connection between the first pressing member, the second pressing member, the wire connecting member, the auxiliary electric conduction member and the power supply wire in the second state provided in the embodiment of the present application, where the first pressing member 133 and the second pressing member 131 are not abutted, and the second state refers to the state where the first pressing member 133 and the second pressing member 131 are abutted, please refer to fig. 4 and fig. 5, in the process of acting on the wire connecting member 132 through the through hole, the first pressing member 133 moves relatively towards the second end of the auxiliary electric conduction member 140 until the second end of the first pressing member 133 and the second pressing member 131 clamp the end of the power supply wire 200 when the first pressing member 133 and the second pressing member 131 are abutted.

The housing 110 may be made of an insulating material such as polyvinyl chloride (polyvinyl chloride, PVC), polycarbonate (PC), or the like.

The housing 110 made of the insulating material can reduce the possibility that the housing 110 is electrified due to the contact between the housing 110 and the electrical conductor inside the housing 110, thereby causing current leakage and ensuring the use safety of the connector 100.

The main electric conduction piece 120 penetrates through the shell 110, one end of the main electric conduction piece 120 is electrically connected with the outlet end of the contactor, and the other end of the main electric conduction piece 120 is electrically connected with the inlet end of the circuit breaker.

The primary electrical conductor 120 may be a copper piece, a stainless steel piece, or other metal piece that may conduct electricity.

The housing 110 may be provided with a through hole penetrating the housing 110 in the alignment direction OX of the contacts and the connector 100, through which the main electric conductor 120 is penetrated. One end of the main electric conduction piece 120 is connected with the outgoing line end of the contactor, and the other end of the main electric conduction piece 120 is connected with the incoming line end of the circuit breaker, so that electric connection between the contactor and the circuit breaker is realized.

The main electrical conductor 120 may also be injection molded with the housing 110, so that the connection between the main electrical conductor 120 and the housing 110 is more secure, and the main electrical conductor 120 is less likely to rotate relative to the housing 110, so that the connection between the contactor and the circuit breaker is more reliable.

The housing 110 has an auxiliary electric conductor 140 mounted thereon. The auxiliary electric conductor 140 may be detachably mounted to the housing 110 by means of a connection such as a snap-fit connection or a screw-connection.

The auxiliary electrical conductor 140 may be an integrally formed rigid electrical conductor, in which case the auxiliary electrical conductor 140 may be made of a conductive material such as stainless steel, copper, or the like.

The auxiliary electrical conductor 140 may also comprise a plurality of segments. The section where the first end of the auxiliary electric conduction member 140 is located, and the section where the second end of the auxiliary electric conduction member 140 is located may be a columnar structure, a clip structure, or a sheet structure with a perforation, and the section between the section where the first end of the auxiliary electric conduction member 140 is located and the section where the second end of the auxiliary electric conduction member 140 is located may be a copper pillar, or may be a copper braid.

The connection terminal 130 is connected to the housing 110. There are various positions of the connection terminals 130 along the arrangement direction OX of the contacts and the connector 100.

For example, referring to fig. 1, the connection terminal 130 may be disposed at a side of the connector 100 away from the contactor.

For example, fig. 6 is a schematic structural diagram of another connector provided in the embodiment of the present application, referring to fig. 6, the connection terminal 130 may also be disposed on a side of the connector 100 close to the contactor.

Next, the structure of the connection terminal 130 will be specifically described taking an example in which the connection terminal 130 is disposed on the side of the connector 100 away from the contactor.

Referring to fig. 4 and 5, the connection terminal 130 may include a connection member 132, a first pressing member 133 and a second pressing member 131.

The first pressing member 133 is fixedly sleeved at the first end of the wire connecting member 132, and the second end of the auxiliary electric conduction member 140 is movably disposed at the first end of the wire connecting member 132 away from the first pressing member 133. In this way, when the second end of the auxiliary electric conductor 140 and the first pressing member 133 are connected to the wire connecting member 132, respectively, the second end of the auxiliary electric conductor 140 and the first pressing member 133 are spaced apart, and the end of the power supply line 200 can be disposed between the second end of the auxiliary electric conductor 140 and the first pressing member 133. Since the first pressing member 133 is fixedly sleeved on the wire connecting member 132, the second end of the auxiliary electric conduction member 140 is movably disposed on the wire connecting member 132 away from the first pressing member 133. The first pressing member 133 may also move toward the second end of the auxiliary electric conduction member 140 when the operator passes through the through hole such that the wire member 132 moves toward the second end of the auxiliary electric conduction member 140.

The second pressing member 131 is movably sleeved at the second end of the wire connecting member 132 through the through hole. The wire connection member 132 is movable within the through hole with respect to the second pressing member 131. When the first pressing member 133 moves toward the second end of the auxiliary electric conductor 140 and the first pressing member 133 and the second pressing member 131 abut, the first pressing member 133 and the second end of the auxiliary electric conductor 140 clamp the end of the power supply line 200. In this way, along the moving direction of the first pressing member 133, the second pressing member 131 can limit the position of the first pressing member 133, so that the second end of the auxiliary electric conduction member 140, the end of the power supply line 200 and the first pressing member 133 are in relatively tight contact, and are not easy to shake, thereby improving the wiring reliability between the power supply line 200 and the auxiliary electric conduction member 140.

In actual use, when the power feeding wire 200 is connected to the first pressing member 133 and the second end of the auxiliary electric conductor 140, the wire connecting member 132 can be moved through the through hole in a direction away from the second end of the auxiliary electric conductor 140, so that a gap exists between the first pressing member 133 and the second end of the auxiliary electric conductor 140, the power feeding wire 200 is inserted into the gap, and then the wire connecting member 132 is moved through the through hole in a direction close to the second end of the auxiliary electric conductor 140 until the first pressing member 133 and the second pressing member 131 abut, and the second ends of the first pressing member 133 and the auxiliary electric conductor 140 clamp the end of the power feeding wire 200.

The end surface of the first pressing member 133 facing the second pressing member 131 may be an arc surface, may be a plane surface, or may be provided with a protrusion on the end surface of the first pressing member 133 facing the second pressing member 131. The end surface of the second pressing member 131 facing the first pressing member 133 may be the same as or different from the end surface of the first pressing member 133 facing the second pressing member 131, that is, the two surfaces of the first pressing member 133 facing the second pressing member 131 may be bonded, or may be bonded but not completely bonded.

The wire member 132 and the first pressing member 133 may be made of a conductive material. The second pressing member 131 may be made of an insulating material.

Since the wiring member 132 is connected to both the auxiliary electric conductor 140 and the power supply line 200, the auxiliary electric conductor 140 is connected to the power supply line 200. Because the first end of the auxiliary electric conduction member 140 is electrically connected with the coil terminal of the contactor, the coil of the contactor can be electrically connected with the power supply line 200, so that the coil of the contactor can be electrified or powered off, the contact mechanisms of the contactor are contacted or separated, the switching of the working state of the contactor is realized, and the circuit is further protected.

When the first pressing member 133 and the second pressing member 131 are abutted, the second end of the wiring member 132 may be flush with the end surface of the second pressing member 131 opposite to the first pressing member 133, or the second end of the wiring member 132 may be lower than the end surface of the second pressing member 131 opposite to the first pressing member 133, so that the wiring member 132 may be prevented from protruding out of the second pressing member 131, the possibility of an electric shock accident caused by the incorrect touching of the second pressing member 131 by an operator is reduced, and the use safety of the connector 100 is further ensured.

In this embodiment, the first end of the auxiliary electric conduction member 140 is electrically connected with the coil terminal, and the second end of the auxiliary electric conduction member 140 is connected with the wiring member 132 in the wiring terminal 130, so that the auxiliary electric conduction member 140 can lead out the coil terminal to the outside of the contactor, the possibility that the connector 100 and the circuit breaker shield the coil terminal is reduced, and wiring between the power supply line 200 and the coil terminal is conveniently realized.

When the first pressing member 133 moves toward the second end of the auxiliary electric conductor 140 and the first pressing member 133 and the second pressing member 131 abut, the first pressing member 133 and the second end of the auxiliary electric conductor 140 clamp the end of the power supply line 200. Thus, along the moving direction of the first pressing member 133, the second pressing member 131 can limit the position of the first pressing member 133, so that the second end of the auxiliary electric conduction member 140, the end portion of the power supply line 200 and the first pressing member 133 are in relatively tight contact, and are not easy to shake, so that the connection reliability between the power supply line 200 and the auxiliary electric conduction member 140 is improved, and the first end of the auxiliary electric conduction member 140 is electrically connected with the coil terminal of the contactor, so that the electrical connection between the power supply line 200 and the coil terminal of the contactor can be realized, and the connection reliability between the power supply line 200 and the coil terminal of the contactor is ensured.
