Description

Technical Field

[0001] The utility model relates to the technical field of direct current contactors, in particular to a direct current contactor which is convenient for wiring and installation. Background Art

[0002] A DC contactor is a contactor whose core is controlled by a DC coil. Its load can be either DC or AC. Since the attraction coil of the DC contactor is connected to DC, there is no impact starting current and no violent impact of the core. Therefore, it has a long life and is suitable for occasions with frequent start and stop.

[0003] A Chinese utility model patent with announcement number CN220272389U discloses a DC contactor with stable connection. The device effectively avoids the part where the plug of the cable is connected to the terminal being directly exposed to the outside during actual use by setting a hinge shaft, a first clamping plate, and a second clamping plate. Therefore, there is no rubber layer on the outermost side of the cable to protect it. When the cable is bent, this part is most likely to shift and cause the connection to loosen. With respect to the above-mentioned related technologies, the inventor believes that there are the following defects:

[0004] When the device is actually used, it is necessary to control and clamp the two groups of cables separately. Since it is difficult to limit and fix the two groups of cables at the same time, the operation steps of the device are increased, thereby reducing the convenience of operating the device. For this reason, we provide a DC contactor that is easy to wire and install. Utility Model Content

[0009] As a further improvement of the above solution, the first clamp and the second clamp are both semicircular ring structures and have the same specifications and sizes.

[0010] As a further improvement of the above solution, guide members are symmetrically fixedly connected to both sides of the top of the DC contactor body, and the guide members are slidably connected to the vertical rods on the same side.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Embodiment 1:

[0024] Please combine Figure 1-3 , a DC contactor that is easy to install and connect in this embodiment includes:

[0025] A DC contactor body 1, with a cable 2 symmetrically plugged into the top of the DC contactor body 1;

[0026] The anti-slip assembly comprises two groups of clamping plates 101 symmetrically arranged on one side of the connection between the two groups of cables 2 and the DC contactor body 1, and a second clamping plate 102 is arranged on the other side of the connection between the cable 2 and the DC contactor body 1. The clamping plates 101 and 102 are both semicircular ring structures and have the same specifications and sizes. Both sides of the clamping plate 101 are fixedly connected with L-shaped brackets 103, and both sides of the top of the DC contactor body 1 are symmetrically and movably connected with vertical rods 104. A connecting rod 105 is hinged between the upper part of the vertical rod 104 and the second clamping plate 102 through a hinge, and a connecting rod 106 is hinged between the bottom end of the vertical rod 104 and the end of the L-shaped bracket 103 through a hinge. The upper parts of the four groups of vertical rods 104 are fixedly connected with the same connecting plate 107, and the top of the DC contactor body 1 is rotatably connected with a screw rod 108 and is threadedly connected with the connecting plate 107. The top of the DC contactor body 1 Guide pieces 109 are symmetrically fixedly connected on both sides of the part, and the guide pieces 109 are slidably connected to the vertical rod 104 on the same side, which can play a certain guiding role in the vertical movement of the vertical rod 104; slide rails 110 are symmetrically fixedly connected on both sides of the top of the DC contactor body 1; sliders 111 are symmetrically fixedly connected to the bottom of the second clamping plate 102 and are slidably connected to the slide rails 110, which can play a certain guiding role in the horizontal movement of the second clamping plate 102; guide rods 3 are symmetrically fixedly connected on both sides of the screw rod 108 and the guide rods 3 are slidably connected to the connecting plate 107, which can play a certain guiding role in the vertical movement of the connecting plate 107; a guide block is fixedly connected to the bottom center of the L-shaped bracket 103; a guide groove is provided at the position of the guide block at the top of the DC contactor body 1 corresponding to the guide block and is slidably connected to the guide block, which can play a certain guiding role in the horizontal movement of the clamping plate 101.

[0027] The implementation principle of a DC contactor that is easy to wire and install in the embodiment of the present application is as follows: after the two groups of cables 2 are respectively plugged into the DC contactor body 1, the screw rod 108 is rotated, and the screw rod 108 is rotated to drive the connecting plate 107 threadedly connected thereto to move vertically downward, and the downward movement of the connecting plate 107 will drive the four groups of vertical rods 104 to move downward together, and the vertical rod 104 and the hinged effect between the L-shaped bracket 103 and the connecting rod 106, and the sliding cooperation between the guide block and the guide groove, so that the two pairs of L-shaped brackets 103 on the left and right sides can be pushed to move toward each other at the same time, thereby driving the two groups of clamping plates 101 on the left and right sides to approach the plug-in point of the two groups of cables 2 and the DC contactor body 1 respectively and simultaneously, and at the same time, the hinged effect between the vertical rod 104 and the clamping plate 102 and the connecting rod 105 is utilized. The sliding cooperation between the slider 111 and the slide rail 110 enables the two groups of clamp plates 102 to be pushed toward the connection between the two groups of cables 2 and the DC contactor body 1 at the same time. When the two groups of clamp plates 102 are in contact with the clamp plates 1 101 on the same side, the connection between the two groups of cables 2 and the DC contactor body 1 can be clamped and limited, thereby realizing the rapid reinforcement of the connection between the device. The operation is simple, convenient and fast, and effectively avoids the difficulty in limiting and fixing the two groups of cables 2 at the same time, which increases the operation steps of the device, thereby reducing the convenience of operating the device. On the contrary, when the screw rod 108 is rotated in the opposite direction, the connection between the cable 2 and the DC contactor body 1 can be released to facilitate the separation of the cable 2 and the DC contactor body 1.

[0028] Embodiment 2:

[0029] Based on Example 1, this embodiment is further improved in that a knob is coaxially fixedly connected to the top of the screw rod 108, and an insulating rubber sleeve is provided on the outside of the knob to facilitate the rotation of the screw rod 108 and also to play a protective role to prevent electric shock.

[0030] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
