Description

[Technical Field]

[0001] This utility model relates to an electromagnetic contactor for a power winch, specifically an electromagnetic contactor assembled inside the electrical control box of a power winch, wherein the rod that is energized by the power source is located on the side facing the support frame, thereby reducing the overall height, and the plug for the signal connection line is located on the front, facilitating smooth insertion. [Background Technology]

[0002] A "powered winch" is a powered machine used to hoist heavy objects or tow loads. Common examples include "lifting winches" used for vertically lifting goods from high-rise buildings; and cable winches installed on jeeps or off-road vehicles for towing other vehicles (for rescue by others) or for escaping danger in dangerous situations (for self-rescue). Commonly used powered winches include... Figure 1 As shown, a power source 11 (e.g., a power motor, electric motor) is provided on one side to output power that can be controlled to change forward or reverse. A reduction gear 12 is provided on the other side. The power source 11 and the reduction gear 12 are connected by a drive shaft (not shown) to transmit power. The power source 11 and the reduction gear 12 are also connected and supported by a support frame 13. A pulley 14 is provided inside the support frame 13, and the drive shaft passes unobstructed through the pulley 14. The power provided by the power source 11 is transmitted to the reduction gear 12 via the drive shaft. After appropriate deceleration, it drives the sheave 14 to rotate (forward or reverse) to release or retract the rope. A cable handler 15 can be mounted on the front of the support frame 13. The front end of the rope (not shown) wound on the sheave 14 passes through the cable handler 15. A weighted hook (not shown) can be fitted onto the front end of the cable to hook a load (heavy objects, other vehicles, or other items) to move the load. In addition, since the powered winch is mainly controlled by remote control, it must be equipped with an electrical control box and a remote control for use. Figure 1 As shown, the existing power winch consists of an electrical control box 16 mounted on a support plate and connected to the support frame 13, so that the electrical control box 16 is mounted above the power source 11 for use, which emphasizes practicality; later, as Figure 2 The configuration shown involves mounting the control box 16 on the two side supports of the support frame 13, meaning the control box 16 is supported by the support frame 13, thus emphasizing the overall symmetry of the item; recently, there have been... Figure 3 The configuration shown places the control box 16 above the power source 11 and combines the control box 16 and the power source 11 into a single assembly, aiming to minimize the size and thus combining practicality with aesthetics.

[0003] The control box 16 must be electrically connected to the power source 11 and a remote controller (not shown). The function of the control box 16 is to receive the control signals sent by the remote controller. Then, the control box 16 further controls the start or stop of the power source 11 and controls the rotation direction and speed of the power source 11. Therefore, the control box 16 and the power source 11 must be physically connected. Since the connection between the control box 16 and the remote controller is an electrical connection for control signals, the two can choose to use wireless or wired remote control modes for signal transmission and reception.

[0004] The electrical control box 16 mainly houses an electromagnetic contactor and necessary electrical control board. The electrical control board receives control signals from the remote control and, according to the requirements of the control signals, controls the start or stop of the power source 11 via the electromagnetic contactor, as well as the rotation direction and speed of the power source 11. Therefore, the outer surface of the electromagnetic contactor is provided with rods that are electrically connected to the power source 11, and pins that are electrically connected to the electrical control board.

[0005] Currently, the electromagnetic contactors installed in the electrical control box on existing powered winches can be roughly divided into two types, such as... Figure 4 and Figure 5 As shown, where, Figure 4 and Figure 5 The electromagnetic contactors 20 shown all have a plurality of (three) connecting rods 21 and three inserts 22 on their outer surface. The difference is that... Figure 4 Insert 22 faces upwards. Figure 5 The only difference is that the insert 22 faces downwards. During assembly, the electromagnetic contactor 20 spans across the power source 11, with the plurality of rods 21 facing upwards and the three inserts 22 located on the side facing the support frame 13. Then, the plurality of rods 21 are connected to the electrical connection rods protruding from the top surface of the power source 11 by cables or wide plates and then locked with nuts to achieve complete power transmission. Then, the electrical control board is positioned and the signal connection wires are plugged into the inserts 22. In actual operation, because the electromagnetic contactor 20 and the power source 11 have many cables or wide plates occupying most of the space, the operation of plugging the signal connection wires into the inserts 22 is often hampered in the confined space and requires great patience to complete, especially when... Figure 4 In the existing electromagnetic contactor 20 shown, the middle rod 21 of the three is connected to the positive terminal of the battery, while the middle insert 22 of the three is connected to the negative terminal of the battery. Figure 4It can be seen that the distance between the middle rod 21 and the middle insert 22 is too close. Therefore, if the assembler (assembler) is not careful when connecting the power, the positive and negative terminals may come into contact, which will cause a short circuit and electric shock. Therefore, this utility model is designed to improve the design, hoping that the assembly and wiring of the electromagnetic contactor can be carried out smoothly in the configuration of the power winch. [Utility Model Content]

[0006] The main objective of this invention is to provide an electromagnetic contactor for a power winch that allows for convenient and smooth wire insertion.

[0007] To achieve the above objectives, this utility model proposes an electromagnetic contactor for a power winch. The power winch has a power source on one side and a reduction gear on the other side. A support frame connects and supports the power source and the reduction gear. A sheave is installed inside the support frame. The power output from the power source is transmitted to the reduction gear through the sheave via a drive shaft without contact. After reduction, the sheave rotates. The power winch has an electrical control box, which is locked to the top surface of the power source and electrically connected to it. An electromagnetic contactor and an electrical control board are installed inside the electrical control box. The electromagnetic contactor has a plurality of connecting rods and three inserts on its outer surface. The feature is that the plurality of rods are located on the side facing the support frame, which reduces the overall height, and the three inserts are located on the front of the electromagnetic contactor, making the insertion of the three inserts relatively convenient and smooth.

[0008] The advantages and beneficial effects of this utility model are as follows: the rod that is connected to the power source on the electromagnetic contactor assembled in the electrical control box of the power winch is located on the side facing the support frame, which reduces the overall height. The plug for the signal connection line is set on the front of the electromagnetic contactor, so that the action of plugging the signal connection line into the plug can be completely unrestricted in terms of spatial layout, which is extremely convenient and smooth.

Detailed Implementation Methods

[0025] This utility model embodiment is essentially a powered winch. Please refer to [link / reference]. Figure 6 and Figure 7 As shown, the power winch has a power source 31 (e.g., a power motor or electric motor) on one side and a reduction gear 32 on the other side. The power source 31 and the reduction gear 32 are connected and supported by a support frame 33. A sheave 34 is provided in the internal space of the support frame 33. The power output from the power source 31 is transmitted to the reduction gear 32 through the sheave 34 via a drive shaft (not shown) without contact. After appropriate deceleration, the sheave 34 is driven to rotate, so as to release (not shown) or retract the rope when needed.

[0026] An electrical control box 36 is locked to the top surface of the power source 31. The electrical control box 36 mainly houses an electromagnetic contactor 40 and necessary electrical control components (not shown in the figure). Please refer to [the relevant documentation]. Figure 8 As shown, the electromagnetic contactor 40 of this utility model has a plurality of (three) connecting rods 41 and three inserts 42 on its outer surface. The main improvement is that the plurality of rods 41 are located on the side facing the support frame 13, and the three inserts 42 are located on the front of the electromagnetic contactor, also facing the support frame 13. Therefore, as Figure 9 and Figure 10 As shown, when assembling the electromagnetic contactor 20, it is fixed across the top surface of the power source 11. Since the multiple connecting rods 41 face the electrical connecting rods 311 protruding from the top surface of the power source 31, it is convenient to hang cables or connect wide plates between the rods 41 and the electrical connecting rods 311 for power supply. Moreover, since the three inserts 42 are located on the front of the electromagnetic contactor and also face the support frame 13, the operation of inserting signal connection lines into the inserts 42 is completely unrestricted in terms of spatial layout, which is extremely convenient and smooth.

[0027] Compared to the electromagnetic contactor 20 in the existing examples described above, this invention, in terms of assembly and use, significantly reduces the overall height because the plurality of rods 41 are located on the side facing the support frame 13. Simultaneously, the three inserts 42 are positioned on the front, also facing the support frame 13, facilitating smooth insertion and connection, thus demonstrating inventiveness. Furthermore, compared to the aforementioned... Figure 4 The existing electromagnetic contactor 20 shown has a deficiency in assembly, where the middle rod 21 and the insert 22 are too close together, which may easily cause short circuits and electric shocks. In contrast, in this utility model, the middle rod 41 and the insert 42 are far apart, so there is no risk of short circuits or electric shocks. It is obviously inventive.
