TECHNICAL FIELD

[0001] The present application relates to the technical field of low-voltage electrical apparatus, in particular to a contactor. BACKGROUND

[0002] The contactor is a kind of switch electrical apparatus. Based on different use scenarios, the contactor can have different functions. Exemplarily, the contactor can control the on-off of the circuit, the contactor can also provide overload protection, undervoltage protection, etc. for the circuit, the contactor can also be used to start the motor or stop the motor, and can also control the rotating direction of the motor.

[0003] Based on the structure of the existing contactor, the efficiency of connecting the external lead wire with the contactor is low during the wiring process of the contactor. CONTENT OF THE UTILITY MODEL

[0004] The present application provides a contactor, which can improve the wiring efficiency of the external lead wire and the contactor during the wiring process of the contactor through the plug-in structure.

[0005] In a first aspect, the present application provides a contactor, which includes a shell assembly and a plug-in structure. The shell assembly includes a receiving cavity, and the cavity wall of the receiving cavity is provided with a mounting hole. The plug-in structure is clamped into the receiving cavity, and the plug-in structure includes a wiring port, at least part of the wiring port is exposed from the mounting hole, so that the external lead wire can be plugged into the plug-in structure through the wiring port.

[0006] Compared with the prior art, by adjusting the adjusting screw of the wiring terminal, the wiring terminal can clamp the external lead wire to realize the electrical connection between the external lead wire and the contactor. In the example of the present application, the plug-in structure is clamped into the receiving cavity, and the wiring port of the plug-in structure is exposed from the mounting hole of the shell assembly, so that the external lead wire can be inserted into the wiring port to realize the electrical connection between the external lead wire and the plug-in structure, and then realize the electrical connection between the external lead wire and the contactor, thereby saving the step of adjusting the adjusting screw and improving the connection efficiency of the external lead wire and the contactor.

[0007] The external lead wire can be inserted into the wiring port to realize the electrical connection between the external lead wire and the plug-in structure. In the case that the external lead wire needs to be separated from the plug-in structure, an external force can be applied to the external lead wire to move the external lead wire away from the plug-in structure, so as to separate the external lead wire from the plug-in structure, and then quickly separate the external lead wire from the contactor, which is convenient for the operator to maintain or replace the contactor.

[0008] In addition, in the prior art, by adjusting the adjusting screw to clamp the external lead, the electrical connection between the external lead and the contactor is realized, which may cause part of the external lead or other conductive structure to be exposed, thereby reducing the safety of the contactor. In the example of the present application, the external lead can be inserted into the plug-in structure from the wiring port, reducing the possibility of external lead exposure and ensuring the safety of the contactor.

[0009] In some possible implementation manners, the contactor further comprises a first clamping structure and a second clamping structure. The first clamping structure is arranged on the cavity wall of the accommodating cavity. The second clamping structure is arranged on the plug-in structure, and the first clamping structure and the second clamping structure are clamped and matched.

[0010] In the example of the present application, the first clamping structure is arranged on the cavity wall of the accommodating cavity, and the second clamping structure is arranged on the plug-in structure. By clamping and matching the first clamping structure and the second clamping structure, the plug-in structure can be clamped to the cavity wall of the accommodating cavity, and the clamping of the plug-in structure and the shell assembly is realized.

[0011] In some possible implementation manners, the first clamping structure is a protruding structure, the second clamping structure is a groove structure, and at least part of the protruding structure extends into the groove structure. Alternatively, the first clamping structure is a groove structure, the second clamping structure is a protruding structure, and at least part of the protruding structure extends into the groove structure.

[0014] In the examples of the present application, the third clamping structure is arranged on the cavity wall of the accommodating cavity, the second clamping structure is arranged on the first side of the plug-in structure, and the fourth clamping structure is arranged on the second side of the plug-in structure, the first side and the second side being different sides of the plug-in structure. Therefore, the third clamping structure cooperates with the fourth clamping structure, and the first clamping structure cooperates with the second clamping structure to limit the position of the plug-in structure relative to the shell assembly from different positions, thereby ensuring the cooperation reliability of the plug-in structure and the shell assembly, reducing the amplitude of the shaking of the plug-in structure relative to the shell assembly, and reducing the possibility of the separation of the external lead wire from the shell assembly due to the shaking of the plug-in structure relative to the shell assembly.

[0015] In some possible implementation manners, the contactor further includes a coil framework, the coil framework is mounted to the shell assembly, and the coil framework is fixedly connected to the side of the plug-in structure away from the mounting hole.

[0016] In the examples of the present application, on the basis of the clamping of the plug-in structure and the shell assembly, the coil framework is mounted to the shell assembly, and the coil framework is fixedly connected to the side of the plug-in structure away from the mounting hole. Therefore, the connection reliability of the plug-in structure and the coil framework can be further ensured by the connection of the coil framework and the plug-in structure, and the amplitude of the shaking of the plug-in structure relative to the shell assembly is reduced.

[0017] In some possible implementation manners, the contactor further includes a limiting structure, the limiting structure is arranged on the coil framework, and the limiting structure is clamped to the third side of the plug-in structure, the third side, the second side, and the first side being different sides of the plug-in structure.

[0018] According to the contactor provided in the examples of the present application, in the case of the fixed connection of the coil framework and the plug-in structure, the limiting structure is arranged on the coil framework and can be clamped to the plug-in structure. Therefore, the connection reliability of the coil framework and the plug-in structure can be further ensured by the cooperation of the limiting structure and the plug-in structure.

[0056] Exemplarily, the present application provides a contactor, please refer to Figures 1 to 5 The contactor 100 includes a housing assembly and a plug-in structure 130. The housing assembly includes a receiving cavity, and a cavity wall of the receiving cavity is provided with a mounting hole. The plug-in structure 130 is clamped into the receiving cavity, and the plug-in structure 130 includes a wiring port 135. At least part of the wiring port 135 is exposed from the mounting hole, so that an external lead can be plugged into the wiring port 135 and plugged into the plug-in structure 130.

[0057] The contactor 100 can be a single control contactor, and the contactor 100 can also be a double control contactor. The present application does not make specific limitations on this, and the wiring mode of the contactor 100 can be adjusted based on user demand, thereby adjusting the type of the contactor 100.

[0058] The housing assembly is made of insulating material, such as polyvinyl chloride, polycarbonate (also known as PC plastic), etc.

[0059] The housing assembly made of insulating material can reduce the possibility of current escaping from the inside of the housing assembly to the outside of the housing assembly, thereby ensuring the safety of the contactor 100.

[0060] The housing assembly can be composed of multiple housings. Exemplarily, the housing assembly includes a first housing 110 and a second housing 120. The first housing 110 includes a first receiving groove 111. The second housing 120 includes a second receiving groove 121, and the first receiving groove 111 and the second receiving groove 121 cooperate to form a receiving cavity. A cavity wall of the receiving cavity is provided with a mounting hole.

[0061] The plug-in structure 130 can be clamped into the receiving cavity. The plug-in structure 130 can be clamped into the receiving cavity by cooperation of buckles and hooks, cooperation of protrusions and grooves, etc. The present application does not make specific limitations on the way in which the plug-in structure 130 is clamped into the receiving cavity.

[0062] The plug-in structure 130 can include at least one wiring port 135. In the case where the plug-in structure 130 is clamped into the receiving cavity, at least part of the wiring port 135 is exposed from the mounting hole. At this time, the external lead can be inserted into the wiring port 135 from the mounting hole and plugged into the wiring port 135, thereby realizing the electrical connection between the external lead and the plug-in structure 130.

[0063] The wiring port 135 can be a rectangular port, or the wiring port 135 can be a circular port. The wiring port 135 meets the specifications of the current standard, so that the plug-in structure 130 can be electrically connected with more types of electrical appliances, thereby expanding the application range of the contactor 100.

[0064] The external wire can be a power supply wire, or the external wire can be a wire for connecting other electrical appliances to the contactor 100. The other electrical appliances can be electrical machines, programmable logic controllers (PLCs), and the like.

[0065] Compared with the prior art, the external wire is electrically connected to the contactor by adjusting the adjusting screw of the wiring terminal to clamp the external wire. In the example of the present application, the plug-in structure 130 is clamped into the accommodating cavity, and the wiring port 135 of the plug-in structure 130 is exposed from the mounting hole of the shell assembly, so that the external wire can be inserted into the wiring port 135 to electrically connect the external wire with the plug-in structure 130, thereby electrically connecting the external wire with the contactor 100. The step of adjusting the adjusting screw is saved, and the connection efficiency of the external wire with the contactor 100 is improved.

[0066] The external wire can be inserted into the wiring port 135 to be plug-in connected with the plug-in structure 130, thereby electrically connecting the external wire with the plug-in structure 130. In the case where the external wire needs to be separated from the plug-in structure 130, an external force can be applied to the external wire to move the external wire away from the plug-in structure 130, thereby separating the external wire from the plug-in structure 130, and further separating the external wire from the contactor 100, which facilitates the maintenance or replacement of the contactor 100 by the operator.

[0067] In addition, in the prior art, the external wire is clamped by adjusting the adjusting screw to electrically connect the external wire with the contactor, which can cause part of the external wire or other conductive structures to be exposed, thereby reducing the safety of the contactor. In the example of the present application, the external wire can be inserted into the plug-in structure 130 from the wiring port 135, thereby reducing the possibility of the external wire being exposed, and ensuring the safety of the contactor 100.

[0068] Based on the contactor 100 provided in the above example, please refer to Figure 2 , Figure 3 and Figure 5 , the contactor 100 further comprises a first clamping structure 122 and a second clamping structure 131. The first clamping structure 122 is arranged on the cavity wall of the accommodating cavity. The second clamping structure 131 is arranged on the plug-in structure 130, and the first clamping structure 122 and the second clamping structure 131 are clamped and matched.

[0069] The first clamping structure 122 can be any one of a protrusion structure and a groove structure, and the corresponding second clamping structure 131 is the other one of the protrusion structure and the groove structure.

[0070] The first clamping structure can also be any one of a buckle structure and a hook structure, and the corresponding second clamping structure is the other one of the buckle structure and the hook structure. The specific structure of the first clamping structure 122 and the second clamping structure 131 is not limited in the present application.

[0071] The first clamping structure 122 can be provided with one, and the first clamping structure can also be provided with multiple, for example, the first clamping structure can be provided with two, three, four or even more. The number of the second clamping structure 131 is equal to the number of the first clamping structure 122, and the first clamping structure 122 and the second clamping structure 131 correspond one by one.

[0072] In the case where the first clamping structure 122 is provided with one, the first clamping structure 122 is arranged on the cavity wall of the accommodating cavity, and specifically can be arranged on the groove wall of the first accommodating groove 111. The first clamping structure 122 can also be arranged on the groove wall of the second accommodating groove 121. The second clamping structure 131 is arranged on the plug structure 130, and the arrangement position of the second clamping structure 131 corresponds to the arrangement position of the first clamping structure 122, which ensures that the second clamping structure 131 can be clamped with the first clamping structure 122.

[0073] In the case where the first clamping structure is provided with multiple, part of the first clamping structure can be arranged on the groove wall of the first accommodating groove 111, and the other part of the clamping structure can be arranged on the groove wall of the second accommodating groove 121. The first clamping structure can also be arranged on the groove wall of the first accommodating groove 111, and the first clamping structure can also be arranged on the groove wall of the second accommodating groove 121. The present application does not make specific limitation on this.

[0074] The first clamping structure 122 can be arranged on the cavity wall of the accommodating cavity provided with a mounting hole, and the first clamping structure 122 can also be arranged on other cavity walls of the accommodating cavity.

[0075] In the present application, the first clamping structure 122 is arranged on the cavity wall of the accommodating cavity, and the second clamping structure 131 is arranged on the plug structure 130. Through the clamping cooperation of the first clamping structure 122 and the second clamping structure 131, the plug structure 130 can be clamped to the cavity wall of the accommodating cavity, realizing the clamping of the plug structure 130 and the shell assembly.

[0076] The first clamping structure is a protrusion structure, and the second clamping structure is a groove structure, at least part of the protrusion structure extends into the groove structure. Alternatively, the first clamping structure 122 is a groove structure, and the second clamping structure 131 is a protrusion structure, at least part of the protrusion structure extends into the groove structure.

[0077] The protruding structure can be a ridge, a bump, a circular truncated cone, a prismatic truncated cone, a cylinder, a prism, or the like.

[0078] In the examples of the present application, whether the protruding structure is arranged on the cavity wall of the accommodating cavity and the recess structure is arranged on the plug structure 130, or the recess structure is arranged on the cavity wall of the accommodating cavity and the protruding structure is arranged on the plug structure 130, at least part of the protruding structure can extend into the recess structure and be clamped to the cavity wall of the accommodating cavity through the clamping of the protruding structure and the recess structure, thereby achieving the clamping of the plug structure 130 and the shell assembly.

[0079] Based on the contactor 100 provided in the above examples, please refer to Figure 2 , Figure 3 and Figure 5 The second clamping structure 131 is arranged on the first side of the plug structure 130, and the contactor 100 further comprises a third clamping structure and a fourth clamping structure 132. The third clamping structure is arranged on the cavity wall of the accommodating cavity. The fourth clamping structure 132 is arranged on the second side of the plug structure 130, and the second side is different from the first side of the plug structure 130. The fourth clamping structure 132 is clamped and matched with the third clamping structure.

[0080] The third clamping structure and the first clamping structure 122 can be arranged apart from each other, or the third clamping structure and the first clamping structure 122 can be connected.

[0081] Taking the rectangular mounting hole as an example, the first clamping structure 122 can be arranged close to the first side of the wiring port 135, and the second clamping structure 131 is arranged on the first side of the plug structure 130, and the first side of the wiring port 135 corresponds to the first side of the plug structure 130.

[0082] The third clamping structure can be arranged close to the second side of the wiring port 135, and the fourth clamping structure 132 is arranged on the second side of the plug structure 130, and the second side of the wiring port 135 corresponds to the second side of the plug structure 130. The second side and the first side of the plug structure 130 can be arranged adjacent to each other or opposite to each other, and the examples of the present application do not limit this. As long as the third clamping structure and the fourth clamping structure 132 are matched, and the first clamping structure 122 and the second clamping structure 131 are matched, the position of the plug structure 130 relative to the shell assembly can be limited from different positions.

[0083] The fourth clamping structure 132 can be a recess structure or a protruding structure.

[0084] In the case where the fourth clamping structure 132 is a recess structure, the third clamping structure can be a protruding structure.

[0085] In the case that the fourth clamping structure 132 is a protruding structure, the third clamping structure can be a cavity wall of the accommodating cavity, and the third clamping structure can also be a groove structure, which is not specifically limited in the examples of the present application.

[0086] In the examples of the present application, since the third clamping structure is arranged on the cavity wall of the accommodating cavity, and the second clamping structure 131 is arranged on the first side of the plug-in structure 130, and the fourth clamping structure 132 is arranged on the second side of the plug-in structure 130, the first side and the second side are different sides of the plug-in structure 130. Therefore, the third clamping structure cooperates with the fourth clamping structure 132, and the first clamping structure 122 cooperates with the second clamping structure 131, which can limit the position of the plug-in structure 130 relative to the shell assembly from different positions, ensure the cooperation reliability of the plug-in structure 130 and the shell assembly, reduce the amplitude of the plug-in structure 130 relative to the shell assembly, and reduce the possibility of the external lead wire being separated from the shell assembly due to the shaking of the plug-in structure 130 relative to the shell assembly.

[0090] There may be one connecting protrusion 141, or there may be multiple connecting protrusions 141 spaced apart. For example, there may be two, three, four, or even more connecting protrusions 141 spaced apart.

[0091] For example, the side of the plug-in structure 130 facing the coil frame 140 can be rectangular.

[0092] When a connecting protrusion 141 is provided, the connecting protrusion 141 can be provided at any position on the plug-in structure 130 facing the coil frame 140.

[0093] When multiple connecting protrusions 141 are provided, for example, two connecting protrusions 141 can be provided on the diagonal or center line of the plug-in structure 130 facing the coil frame 140. For example, when three connecting protrusions 141 are provided, while ensuring that two connecting protrusions 141 can be provided on the diagonal or center line of the plug-in structure 130 facing the coil frame 140, the third connecting protrusion 141 can be arbitrarily distributed.

[0094] The fixed connection between the coil bobbin 140 and the plug-in structure 130 can be achieved by engaging the first snap-fit ​​structure 122 and the second snap-fit ​​structure 131.

Therefore, the cooperation between the limiting structure and the plug structure 130 can further ensure the connection reliability of the coil framework 140 and the plug structure 130.

[0107] The first conductive member 133 is electrically connected to the first connecting tab 142, and the first connecting tab 142 is electrically connected to the first coil. The first conductive member 133 is arranged through the first connecting port 1351. Therefore, the electrical connection between the first coil and the external connecting wire can be realized through the electrical connection between the first conductive member 133 and the external connecting wire, which facilitates to improve the electrical connection efficiency between the first coil and the external connecting wire.

[0108] The second conductive member 134 is electrically connected to the second connecting tab, and the second connecting tab is electrically connected to the second coil. The second conductive member 134 is arranged through the second connecting port 1352.

[0109] Based on the contactor 100 provided in the above example, please refer to Figure 8 The contactor 100 further comprises a first electrical connecting member. One end of the first electrical connecting member is electrically connected to the first connecting tab 142, and the other end of the first electrical connecting member is electrically connected to the first conductive member 133.

[0110] The side wall of the coil framework 140 is provided with a first wire fixing groove 143, and at least part of the first electrical connecting member is clamped to the first wire fixing groove 143.

[0111] The first wire fixing groove 143 is arranged on the side of the coil framework 140 close to the first connecting tab 142.

[0112] The first wire fixing groove 143 can be a groove arranged on the side wall of the coil framework 140. In the direction of the first shell 110 towards the second shell 120, the side wall of the coil framework 140 can be provided with a plurality of protrusions at intervals. Adjacent two protrusions can cooperate to form the first wire fixing groove 143. The first wire fixing groove 143 can also have other implementation manners, which are not limited in the example of the present application.

[0113] In the example of the present application, the first electrical connecting member is used to electrically connect the first lug 142 and the first conductive member 133. The side wall of the coil former 140 is provided with a first wire fixing groove 143, and at least part of the first electrical connecting member is clamped to the first wire fixing groove 143, which can limit the position of the first electrical connecting member relative to the coil former 140, reduce the amplitude of the first electrical connecting member relative to the coil former 140, and further ensure the electrical connection reliability between the first electrical connecting member, the first lug 142 and the first conductive member 133.

[0114] In some possible implementations, the side wall of the coil former 140 can also be provided with a second wire fixing groove. The second wire fixing groove has a structure similar to that of the first wire fixing groove 143 and plays a similar role. For the structure and role of the second wire fixing groove, please refer to the relevant description of the first wire fixing groove 143 above, which will not be repeated here.

[0115] Based on the contactor 100 provided in the above example, a plurality of first wire fixing grooves 143 are spaced apart.

[0116] By providing a plurality of first wire fixing grooves 143, the position of the first electrical connecting member relative to the coil former 140 can be limited from multiple positions, further reducing the amplitude of the first electrical connecting member relative to the coil former 140, and further ensuring the electrical connection reliability between the first electrical connecting member, the first lug 142 and the first conductive member 133.

[0119] The wire outlet end of the contactor 100 can also be provided as the plug-in structure 130. At this time, since the wire inlet end and the wire outlet end of the contactor 100 are both provided as the plug-in structure 130, when the operator realizes the electrical connection between the contactor 100 and the external lead wire, it is only necessary to insert the external lead wire into the corresponding plug-in structure 130, which can avoid adjusting the adjusting screw and improve the wiring efficiency of the contactor 100 and the external lead wire.

[0120] In the case that the outlet end of the contactor 100 is provided with the plug-in structure 130, the inlet end of the contactor 100 can be provided with a terminal with an adjusting screw.
