Description

Technical Field

[0001] The invention belongs to the technical field of electrical equipment and relates to a switching module. Background Art

[0002] During use, multiple electronic devices need to be connected, and the connectors of many electronic devices face different directions. For example, the leakage protector and the overload protector. The leakage protector is mainly used to protect people from electric shock when a leakage fault occurs in the equipment. It has overload and short-circuit protection functions. It can also be used to protect the line or motor from overload and short circuit. It can also be used as an infrequent switching start of the line under normal circumstances. The overload protector mainly separates the torque limiter when an overload fault occurs, thereby effectively protecting the driving machinery and the load.

[0003] The outlet end of the existing leakage protector is set at the bottom, and the input end of the overload protector is set at the top. Therefore, when the leakage protector needs to be electrically connected to the overload protector, one end of the wire needs to be electrically connected to the outlet end of the leakage protector, and the other end of the wire needs to be connected to the input end of the overload protector. At this time, the wire needs to be wrapped from the lower end of the leakage protector to the upper end of the overload protector along the length of the overload protector and the length of the leakage protector. The wire is long, which makes the wiring of the wire troublesome, makes the installation and fixation of the wire more cumbersome, and affects the appearance. Summary of the Invention

[0004] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a switching module. The technical problem to be solved by the present invention is: how to solve the problem of troublesome wiring between the existing leakage protector and the overload protector.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A switching module includes a vertical connection part connected to a leakage protector and a horizontal connection part connected to an overload protector, characterized in that the upper end of the vertical connection part is connected to the horizontal connection part, and a receiving area for the overload protector to be placed is formed between the vertical connection part and the horizontal connection part, the horizontal connection part has a conductive sheet located in the receiving area and electrically connected to the inlet terminal of the overload protector, and the lower end of the vertical connection part has a wiring terminal electrically connected to the leakage protector.

[0007] Working principle: A vertical connection part and a horizontal connection part are provided, and an accommodating area is formed between the vertical connection part and the horizontal connection part. The overload protector is placed in the accommodating area, and the leakage protector is assembled on the side of the vertical connection part away from the accommodating area. At this time, there is a wiring terminal on the vertical connection part. At this time, the output end of the leakage protector is connected to the wiring terminal through a soft wire, and the input end of the overload protector is connected to the conductive sheet to realize the transitional electrical connection between the leakage protector and the overload protector. The wiring terminal and the conductive sheet are electrically connected through a conductor. Through the setting of the adapter module, the lower end of the vertical connection part can be connected to the lower end of the leakage protector, and the horizontal connection part has a conductive sheet in the accommodating area. At this time, the overload protector is placed in the accommodating area and the input end on it is connected to the conductive sheet on the horizontal connection part, avoiding the need to wrap the wires from the lower end of the leakage protector to the upper end of the overload protector, and making the electrical connection between the leakage protector and the overload protector more convenient, further improving the connection efficiency of the leakage protector and the overload protector.

[0008] In the above-mentioned adapter module, the vertical connecting part includes a base and an end cover covered on the base, and the end cover is provided with a plurality of sockets for the wires or bus bars to pass through. The wiring terminal includes a wiring board arranged in the base and a spring sheet arranged corresponding to the wiring board. The wiring board and the socket are arranged correspondingly, and a clamping area is formed between the wiring board and the spring sheet. The spring sheet can press the wires or bus bars tightly in the clamping area.

[0009] The arrangement of this structure can compress the wire or busbar by the pressure of the spring sheet itself, thereby further improving the switching efficiency of the switching module.

[0010] In the above-mentioned adapter module, the spring piece has a mounting portion, the wiring board is provided with a protrusion, the mounting portion is provided with a mounting hole, and the protrusion is embedded in the corresponding mounting hole.

[0011] The spring piece can be positioned on the wiring board by placing the mounting portion thereon. At this time, the raised portion of the wiring board can be embedded in the mounting hole of the mounting portion, thereby limiting the spring piece and improving the stability of the spring piece setting.

[0012] In the above-mentioned adapter module, the spring sheet also has a clamping portion formed by bending the mounting portion, and the clamping portion has two pressure feet. Both ends of the pressure feet are arranged in a direction away from the cavity wall of the clamping area, and there is a gap between the two pressure feet. The protrusion on the wiring board forms a pressure strip that abuts against the corresponding pressure feet.

[0013] The shape of the presser foot is set in a similar U-shape, so that the contact area between the presser foot and the pressure strip is smaller. There are two presser feet, and there is a gap between the two presser feet, which makes the deformation of the presser foot easier, making it easier to insert the conductor into the socket, thereby further improving the transfer efficiency of the transfer module.

[0014] In the above-mentioned adapter module, the vertical connecting part includes a base plate, which is located on a side close to the horizontal connecting part. A plurality of snap-in pins are provided on the base plate, and a plurality of snap-in seats are provided on the base. The snap-in seats include two oppositely arranged snap-in blocks, and a snap-in groove is provided between the two snap-in blocks in the same snap-in seat. The snap-in pins are embedded in the corresponding snap-in grooves to snap the base plates together.

[0015] The arrangement of this structure makes the splicing and installation of the vertical connection parts more convenient.

[0016] In the above-mentioned adapter module, one end of the end cover extends into the base, and two oppositely arranged limiting blocks are provided on the end cover, and a limiting groove for the conductor to pass through is formed between the two limiting blocks, and the limiting groove is U-shaped.

[0017] The limiting groove can limit the conductor to prevent it from moving around randomly.

[0018] In the above-mentioned adapter module, a reserved hole is provided below the conductive sheet on the transverse connecting portion, and a baffle is provided in the corresponding reserved hole of the transverse connecting portion.

[0019] The setting of the reserved hole allows the baffle to be removed when it is necessary to lead the wire out from the incoming terminal of the overload protector, pass the wire through the reserved hole and connect it to the incoming terminal of the overload protector. When wiring is not required, the baffle does not need to be removed. At this time, the baffle plays a shielding and protective role, preventing the incoming terminal of the overload protector from being exposed.

[0020] Compared with the existing technology, this adapter module has the following advantages: through the setting of the adapter module, the lower end of the vertical connection part can be connected to the lower end of the leakage protector, and the horizontal connection part has a conductive sheet in the accommodating area. At this time, the overload protector is placed in the accommodating area and its upper incoming line end can be electrically connected to the conductive sheet on the horizontal connection part, further improving the connection efficiency of the leakage protector and the overload protector.
