Description

Technical Field

[0001] This utility model relates to the technical field of contactors, and in particular to a device for a shorting contactor for a male wire. Background Technology

[0002] A contactor is a switching device that uses electromagnetic, pneumatic, or hydraulic principles to control the opening and closing of the main circuit. Generally, its working principle is as follows: when the contactor coil is energized, the coil current generates a magnetic field. This magnetic field causes the stationary iron core to generate an electromagnetic attraction, drawing in the moving iron core and actuating the AC contactor contacts. Specifically, the normally closed contacts open, and the normally open contacts close; these actions are linked. When the coil is de-energized, the electromagnetic attraction disappears, and the armature is released by the release spring, causing the contacts to return to their original state—the normally open contacts open, and the normally closed contacts close.

[0003] Contactors are important electrical switching devices with wide applications in power control and automation systems. For example, they can control the current in a circuit: contactors can control the current in a circuit, and this can be achieved by opening or closing the contactor when it is necessary to disconnect or connect the circuit. Contactors can also be used to protect circuits and equipment, such as preventing short circuits, overloads, and other abnormal conditions. Furthermore, contactors can be used to achieve automated control: contactors can be used in conjunction with sensors, controllers, and other components to realize automated control functions.

[0004] Based on this, patent document CN1825719A discloses a contactor and contact method for electronic components. This contactor is capable of making appropriate and uniform contact with multiple electrode terminals in electronic components such as ICs. Each of the multiple contact components has a first contact portion at one end and a second contact portion at the other end. The first contact portion has a recess for accommodating one electrode terminal of the electronic component. A base accommodates and supports the multiple contact components. The first contact portion is movable in a horizontal direction.

[0005] In addition, another patent document with publication number CN101061609A discloses a contactor and a testing method using the contactor. This contactor can be used to electrically connect the terminals of electronic components to an external circuit. It has: a contactor substrate having a plurality of holes; a plurality of contacts formed of conductive material and respectively inserted into the respective holes of the contactor substrate, and a portion protruding from the holes and extending outward; a conductive portion formed on the inner wall surface of each hole. Each contact has a first contact portion and a second contact portion, and is electrically connected to the external circuit through the second contact portion. The first contact portion contacts a terminal of the corresponding electronic component, and the second contact portion contacts the conductive portion in the middle portion of the contact. Furthermore, the test method using the aforementioned contactor disclosed in the patent document is as follows: pressing the electrode of the electronic component onto the first end of the contact protruding from the hole in the substrate, bending the contact by pressing force, so that the middle portion between the first end and the second end opposite to the first end of the contact contacts the conductive part, the conductive part being disposed on the inner wall surface of the hole in the substrate, electrically connecting the electronic component to the circuit board, and performing a test.

[0006] However, existing contactor testing devices still suffer from technical problems such as inadequate heat dissipation, installation convenience, and stability. Specifically, the existing technical solutions primarily maintain contactor spacing by having the assembly personnel first install the contactors onto the guide rails; then, a special sheet metal fixture is used to ensure proper spacing during assembly to meet specified process requirements, without any other auxiliary positioning methods. In this solution, because the guide rails are relatively smooth, additional forces during the transport of electrical aluminum sheets or wiring can cause contactor position shifts, altering their spacing. This hinders workstation division and assembly transport, failing to meet the control standards' requirements for contactor heat dissipation.

[0007] In addition, public line connection jumper blocks are one of the commonly used electrical connection components; however, the public line connection jumper blocks currently on the market are all standard jumper blocks, which are suitable for installation between two contactors or two relays without gaps, and cannot meet the installation requirements of certain special gaps, such as the requirement of a 5mm contact gap in some practical processes. Utility Model Content

[0008] Therefore, it is necessary to provide a contactor common line shorting device to address the technical issues of how to improve the ease of installation and stability of contactors.

[0009] A male wire shorting tab device for a contactor includes: an insulating base, a locking boss structure, a male wire shorting tab, and a shorting cable terminal; a plurality of the locking boss structures are evenly distributed on the side of the insulating base, a plurality of the male wire shorting tabs are evenly distributed on the side of the insulating base, and at least one shorting cable terminal is disposed on the insulating base; a locking boss structure is disposed between every two male wire shorting tabs.

[0010] Furthermore, the insulating bracket has a bracket body, side grooves, and threaded connections.

[0011] Furthermore, the main body of the seat frame has a hollow structure, and several side grooves are provided on the side of the main body of the seat frame.

[0012] Furthermore, a locking boss structure is provided between every two side grooves.

[0013] Furthermore, a male wire shorting piece is provided in each of the side grooves.

[0014] Furthermore, the top of the main body of the bracket is provided with a plurality of threaded connection parts, and each threaded connection part is connected to a shorting cable terminal.

[0015] Furthermore, the locking boss structure is in the shape of an isosceles trapezoid with a long base of 23mm, a short base of 20mm, and a height of 8mm.

[0016] Furthermore, the male wire shorting piece has a U-shaped clamp structure with a thickness of 0.75mm and an anti-rust nickel plating layer on its outer surface.

[0017] Furthermore, the distance between each pair of the aforementioned public wire shorting pieces is set to 48mm.

[0018] In summary, this utility model provides a male wire shorting device for contactors, comprising an insulating base, a locking boss structure, a male wire shorting piece, and a shorting cable terminal. Several locking boss structures are evenly distributed on the side of the insulating base, and several male wire shorting pieces are evenly distributed on the side of the insulating base. At least one shorting cable terminal is disposed on the insulating base. A locking boss structure is disposed between every two male wire shorting pieces. The arrangement of the insulating base and the male wire shorting pieces ensures the required spacing or other distances for external contactors; it also meets the requirements for connection stability and corrosion resistance. Furthermore, the arrangement between the insulating base and the locking boss structures makes the external contactor installation more secure and less prone to loosening. The arrangement of the male wire shorting piece and the shorting cable terminal facilitates user wiring and ensures connection reliability. Therefore, this utility model provides a male wire shorting device for contactors, solving the technical problem of improving the ease of installation and stability of contactors.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0028] Please refer to the following: Figures 1 to 2 This utility model discloses a male wire shorting piece device for a contactor, comprising: an insulating base 1, a locking boss structure 2, a male wire shorting piece 3, and a shorting cable terminal 4; a plurality of locking boss structures 2 are evenly distributed on the side of the insulating base 1, a plurality of male wire shorting pieces 3 are evenly distributed on the side of the insulating base 1, and at least one shorting cable terminal 4 is disposed on the insulating base 1; a locking boss structure 2 is disposed between every two male wire shorting pieces 3.

[0029] Specifically, in the technical solution disclosed in this utility model of a contactor public wire shorting piece device, the insulating bracket 1 is a bracket structure made of insulating material, which is preferably made of plastic material, for example, its main body can be made of thickened insulating PVC material.

[0030] In one specific embodiment, the total length of the outer layer of the insulating bracket 1 can be designed to be 198mm, and its width can be designed to be 11.5mm. To ensure the reliability of electrical wiring, the height design must be no less than 7.25mm; to improve aesthetics, its height design should be less than 14mm; and since the PVC insulation layer is relatively thick, the non-wiring part and the interior of the locking boss structure 2 can be designed as a hollow structure in the middle.

[0031] Furthermore, the locking boss structure 2 serves to isolate and connect the installation; in a specific embodiment, the locking boss structure 2 is an isosceles trapezoid with a long base of 23mm, a short base of 20mm, and a height of 8mm; so that it can be precisely embedded and installed with the wiring structure of the external contactor, thereby improving the stability of the installation structure.

[0032] Furthermore, the male wire shorting piece 3 can be a U-shaped clamp structure with an anti-rust nickel plating layer on its outer surface, and can be evenly arranged on the side of the insulating base 1. In a specific embodiment, the male wire shorting piece can be a 0.75mm thick copper sheet, and its shape design is similar to a standard anti-rust nickel plating U-shaped clamp. A total of 5 segments of the male wire shorting pieces 3 can be arranged on the side of the insulating base 1, with a distance of 48mm between every two segments. When the coil of the external contactor is installed without gaps, the distance between every two segments of the male wire shorting pieces 3 can be set to 43mm, thereby ensuring that the electrical shorting requirement can be met when the contactor is installed with a gap of 5mm.

[0033] Furthermore, several sets of the shorting ribbon cable terminals 4 can also be evenly arranged on the insulating base 1. Their main function is to use one of the shorting ribbon cable terminals 4 to connect to the 220V public line of the whole machine, while the remaining shorting ribbon cable terminals 4 are for backup. For example, if the original shorting ribbon cable terminal 4 is damaged, the remaining shorting ribbon cable terminals can also be used as backup connections. Thus, it can be seen that in the basic scheme of the public line shorting piece device for contactors of this utility model, only one shorting terminal 4 is needed to achieve its function. More specifically, the shorting ribbon cable terminal 4 can be connected to the insulating base 1 by screws. For example, an M2 screw with a thread depth of 2.3mm and a reserved nut hole depth of 1.7mm can be used. When the screw is tightened, the nut can be embedded in the thickened PVC surface of the insulating base 1, avoiding unnecessary contact, increasing risk, and ensuring the reliability of the electrical connection.

[0034] Furthermore, the insulating bracket 1 has a bracket body 101, side grooves 102, and threaded connection parts 103; the bracket body 101 is a hollow structure, and a plurality of side grooves 102 are provided on the side of the bracket body 101, a locking boss structure 2 is provided between every two side grooves 102, and a male wire shorting piece 3 is provided in each side groove 102; a plurality of threaded connection parts 103 are provided on the top of the bracket body 101, and each threaded connection part 103 is correspondingly connected to a shorting ribbon cable terminal 4.

[0035] For further information, please refer to [link / reference]. Figure 3 , Figure 3 This is a structural schematic diagram of a specific application embodiment of the contactor's common wire shorting piece device according to this utility model; as shown... Figure 3As shown, each of the aforementioned male wire shorting pieces 3 can be movably connected to a Fuji contactor 5. The connection point between the side groove 102 and the male wire shorting piece 3 can be precisely embedded into the coil wiring structure of the Fuji contactor 5, thereby improving the connection stability between the two. When several Fuji contactors 5 are arranged and distributed on the side of the insulating base 1, two Fuji contactors 5 can be embedded on both sides of each of the locking boss structures 2, and each locking boss structure 2 can serve as an insulating separation structure between each pair of Fuji contactors 5. More specifically, when used for male wires, the male wire shorting piece 3 and the shorting ribbon terminal 4 are electrically connected, while when used for non-male wires, the male wire shorting piece 3 and the shorting ribbon terminal 4 are not electrically connected.

[0036] In summary, this utility model provides a male wire shorting device for contactors, comprising an insulating base 1, a locking boss structure 2, a male wire shorting piece 3, and a shorting cable terminal 4. The insulating base 1 has several locking boss structures 2 evenly distributed on its side, and several male wire shorting pieces 3 are evenly distributed on its side. At least one shorting cable terminal 4 is mounted on the insulating base 1. A locking boss structure 2 is positioned between every two male wire shorting pieces 3. The arrangement of the insulating base 1 and the male wire shorting pieces ensures a 5mm or other required spacing between external contactors; it also meets the requirements for connection stability and corrosion resistance. Furthermore, the arrangement between the insulating base 1 and the locking boss structures 2 makes the external contactor installation more secure and less prone to loosening. The arrangement of the male wire shorting pieces 3 and the shorting cable terminal 4 facilitates user wiring and ensures connection reliability. Therefore, the present invention provides a public wire shorting device for contactors, which solves the technical problem of how to improve the ease of installation and stability of contactors.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
