Description

Technical Field

[0001] The utility model relates to the technical field of power distribution control contacts, in particular to a power distribution control contact which is convenient for fixing a wire end. Background Art

[0002] Electrical contacts are the main conductive contact materials widely used in relays, contactors, load switches, medium and low voltage circuit breakers, household appliances, automotive appliances and other switching devices. Switching devices are widely used to analyze the voltage and current in closed circuits, and their reliability directly affects the reliable operation of the entire power system.

[0003] However, when installing the power distribution control contact, the staff needs to insert one end of the wire into the wiring slot on the contact. When installing the existing electrical contacts, the staff inserts one end of the wire into the wiring slot and only fixes the wire end with a screw. This not only makes the installation and fixing of the wire end by the staff low in efficiency, but also after long-term use, the screw may slip, so that the wire end falls off, thereby affecting the normal use of the contact.

[0004] In order to solve the above problems, the present application proposes a power distribution control contact that is convenient for fixing the wire ends. Utility Model Content

[0005] The utility model aims to provide a power distribution control contact which is convenient for fixing wire ends, and is mainly used to solve the problem that the existing electrical contacts only limit and fix the wire ends by screws, which not only makes the installation and fixing efficiency of the wire ends by the workers low, but also causes the wire ends to fall off, thereby affecting the normal use of the contacts.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A power distribution control contact for fixing wire ends, comprising a contact body and a plurality of wiring slots opened on the contact body, a plurality of through slots matching the wiring slots are opened on the top and bottom of the contact body, a moving block is slidably connected to the lower end of the inner wall of the through slot, a sliding rod is fixedly connected to the top of the moving block, the upper end of the sliding rod extends out of the contact body and is slidably connected to the contact body, a first spring is sleeved on the outer wall of the sliding rod, the upper end of the first spring is fixedly connected to the inner wall of the through slot, and the lower end is fixedly connected to the outer wall of the sliding rod, and a limiting component is arranged at the lower end of the outer wall of the sliding rod.

[0008] The working principle and beneficial effects of the utility model:

[0009] 1. Working principle: After the staff inserts the wire end into the wiring slot on the contact body, they press the slide bar downward to drive the moving block to move downward. When the bottom of the moving block is pressed against the wire, the limit assembly set on the slide bar can better limit and fix the slide bar, and the power distribution control contact can be used normally.

[0010] 2. Beneficial effect: The movable block moves downward by pressing the slide bar downward. When the movable block moves downward until it is close to the wire, the limit assembly can play a better limiting and fixing role on the slide bar. The advantage of this arrangement is that it not only makes it more convenient for people to install and fix the wire ends, but also makes the connection between the wire and the electrical contact more secure, thereby making the electrical contact more stable when in use.

[0011] Preferably, the limit assembly includes a sliding cavity provided at the lower end of the outer wall of the sliding rod, one end of the inner wall of the sliding cavity is fixedly connected to the telescopic rod, the other end of the telescopic rod is fixedly connected to the limit rod, the outer wall of the telescopic rod is sleeved with a second spring, one end of the second spring is fixedly connected to the inner wall of the sliding cavity, and the other end is fixedly connected to the limit rod, a limit groove matching the limit rod is provided on one side of the contact body, a pressing block is slidably connected inside the limit groove, one end of the pressing block extends out of the contact body, and the other end is fixedly connected to a push rod, and the other end of the push rod is matched with the limit rod. After the staff inserts the wire end into the wiring slot on the contact body, they press the sliding rod downward forcefully to move the moving block toward When the limit rod is completely out of the limit groove, the slide bar will move upward under the action of the first spring, thereby driving the moving block to move upward and away from the wires in the wiring groove, making it easier for people to remove the wires on the electrical contacts.

[0012] Preferably, a symmetrical guide block is fixedly connected to the outer wall of the pressing block, and a guide groove matching the guide block is provided on the inner wall of the limiting groove. When the staff removes the wires on the contact body, they need to press the pressing block on one side of the contact body to make the pressing block slide inside the limiting groove. The guide block provided on the outer wall of the pressing block and the guide groove provided on the inner wall of the limiting groove can better limit and guide the pressing block. This not only makes the pressing block more stable when sliding inside the limiting groove, but also effectively prevents the pressing block from pushing the contact body, thereby effectively ensuring the normal operation of the device.

[0013] Preferably, the bottom of the moving block is set in an arc shape. When the staff presses the sliding rod downward to make the bottom of the moving block close to the wire, by setting the bottom of the moving block as an arc surface, the fit between the bottom of the moving block and the wire can be higher, thereby making the contact better for fixing the wire.

[0014] Preferably, a rubber pad is fixedly connected to the bottom of the moving block, and anti-slip grooves are provided on the bottom of the rubber pad. Since the rubber material has good wear resistance and cushioning properties, the rubber pad is arranged at the bottom of the moving block. This can not only effectively avoid hard contact between the moving block and the wires, thereby providing better protection for the wires, but also make the moving block and the inner wall of the wiring slot clamp the wires with higher stability.

[0015] Preferably, the ends of the slide rod and the pressing block extending out of the contact body are both rounded. When the staff installs and removes the wires on the contact body, they need to press the slide rod and the pressing block respectively. Therefore, by setting the ends of the slide rod and the pressing block extending out of the contact body to be rounded, people's hands can be more comfortable when pressing the slide rod and the pressing block.

[0016] Preferably, the end of the limiting groove close to the slide rod is chamfered. By chamfering the end of the limiting groove close to the slide rod, it is easier to insert the limiting rod into the limiting groove, thereby effectively ensuring the normal operation of the device.
