Description

Technical Field

[0001] The utility model relates to the field of connectors, in particular to a wiring terminal with a mechanical on-off structure. Background Art

[0002] Connecting terminals are accessories used to achieve electrical connections and are part of a connector. They securely connect wires or cables to electrical equipment, ensuring smooth current flow from one point to another and completing various circuit functions. Connecting terminals primarily consist of a terminal block and metal terminals. Wires are typically connected to the metal terminals using screws. Tightening or loosening the wires requires repeatedly turning the screws with a screwdriver, which is inconvenient. Furthermore, existing connecting terminals lack switch indicators, making it difficult for users to understand the terminal's operating status and perform proper operation and maintenance. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a connecting terminal with a mechanical on-off structure, which can be directly inserted into the wire to fasten the connection and is convenient for users to understand the working status of the connecting terminal.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A connecting terminal with a mechanical on-off structure, comprising a housing and a clamping terminal, a clamping spring, a switch indication fixing terminal, a switch indication connecting terminal and a button arranged in the housing, wherein:

[0006] A wire inlet opening is provided on one side of the housing, a button outlet is provided on the other side, and a positioning post is provided below the wire inlet opening in the housing;

[0007] The clamping terminal includes a contact piece, which is installed beside the wire inlet opening. The contact piece extends in the direction of the wire inlet opening and is flush with the top of the wire inlet opening.

[0008] The clamping spring is installed under the contact piece. The clamping spring includes a fixed part and a deforming part. The fixed part is fixed in the shell, the deforming part is tilted upward, and a plug-in part is provided at the front end of the deforming part. The deforming part is used to clamp the wire on the contact piece.

[0009] The switch indication fixed terminal and the switch indication connecting terminal are installed beside the button outlet. The switch indication connecting terminal includes a fixed sheet and a movable sheet. The movable sheet is used to cooperate with the switch indication fixed terminal for connection.

[0010] The button is arranged on the front side of the clamping spring and the switch indication connection terminal. One end of the button is rotatably connected to the positioning column, and the other end extends to the button outlet. The button is provided with a socket connected to the plug-in part, and a positioning groove connected to the movable sheet body. The positioning groove is used to adjust the movable sheet body to be close to or away from the switch indication fixed terminal.

[0011] In some embodiments, the movable sheet body is arc-shaped; the side walls of the positioning groove respectively form an upper push portion and a lower push portion, which respectively match the two sides of the movable sheet body, and the upper push portion is used to push the movable sheet body upward to approach the switch indication fixed terminal, and the lower push portion is used to push the movable sheet body downward away from the switch indication fixed terminal.

[0012] In at least one embodiment, a limiting column is further provided in the housing, and the limiting column is located on the center side of the movable sheet.

[0013] Compared with the prior art, the present invention achieves at least the following beneficial effects:

[0014] 1. When the product wire is inserted into the housing from the wire inlet opening, the wire squeezes the clamping spring, and the clamping spring rotates counterclockwise. When the wire is inserted, the clamping spring rebounds clockwise due to the elastic force and clamps the wire on the contact piece. Under the premise of ensuring tightness, the wire and the clamping terminal are connected. At this time, the product is powered on and easy to use. During the counterclockwise rotation of the clamping spring, it drives the button to rotate counterclockwise, and the positioning groove of the button drives the switch indication connection terminal and the switch fixed terminal to forcibly separate. At this time, the switch indication connection terminal and the switch fixed terminal are in the disconnected state, and the indicator device stops working, so that the user can easily identify that the product has completed the correct connection of the wire.

[0015] 2. When the product wires are pulled out from the wire inlet opening, press the button down to rotate the clamping spring counterclockwise, thereby loosening the wires. At this time, the wires can be taken out and the product is powered off. After the wires are taken out, the clamping spring rebounds clockwise and drives the button to rotate clockwise, and the positioning groove of the button drives the switch indication connection terminal to contact the switch fixed terminal. At this time, the switch indication connection terminal and the switch fixed terminal are in the conductive state, and the switch indication device works, making it easy for users to identify that the product is not connected to the wires.

[0039] In this embodiment, at least two shells 1 are provided, and the two shells 1 are stacked and detachably connected together.

[0040] refer to Figures 5-6 , the method of using the embodiment of the utility model is:

[0041] ① When the product wire 60 is inserted from the wire inlet opening 11 (wire 60 plugged in state): the wire 60 squeezes the clamping spring 3, and the clamping spring 3 rotates counterclockwise. When the wire 60 is inserted, the clamping spring 3 rebounds clockwise due to the elastic force and clamps the wire 60 on the contact piece 21, thereby completing the plugging of the wire 60. At this time, the product is powered on. During the counterclockwise rotation of the clamping spring 3, it drives the button 6 to rotate counterclockwise, and the push-down portion 9 of the button 6 pushes the switch indication connection terminal 5 and the switch fixed terminal to forcibly separate. At this time, the switch indication device connecting the switch indication connection terminal 5 and the switch fixed terminal is in the disconnected state, that is, the switch indication device stops working, thereby facilitating the user to identify that the product has completed the correct connection of the wire 60.

[0042] ② When the product wire 60 is pulled out from the wire inlet opening 11 (the wire 60 is not plugged in): press the button 6 downward to make the clamping spring 3 rotate counterclockwise, thereby loosening the wire 60. At this time, the wire 60 can be taken out and the product is powered off; after the wire 60 is taken out, the clamping spring 3 rebounds clockwise due to the elastic force and drives the button 6 to rotate clockwise, and then the push-up part 8 of the button 6 pushes the switch indication connection terminal 5 to contact the switch fixed terminal. At this time, the switch indication device connected to the switch indication connection terminal 5 and the switch fixed terminal is in the on state, that is, the switch indication device is working, which makes it convenient for users to identify that the product is in the state where the wire 60 is not connected.

[0043] The present invention provides a positioning groove 62 on the button 6 to form a downward push portion 9 and an upward push portion 8. When the wire 60 is inserted and removed, the downward push portion 9 and the upward push portion 8 of the button 6 can push the switch indication connection terminal 5, thereby realizing the disconnection and connection between the switch indication connection terminal 5 and the switch indication fixed terminal 4, realizing the start and stop of the indicating device, and making it convenient for the user to identify the working status of the connection terminal; the present invention adopts a mechanical on-off structure, which can increase the service life of the connection terminal. Since the switch indication connection terminal 5 is pushed by the downward push portion 9 and the upward push portion 8 of the button 6, the material requirements for the switch indication connection terminal 5 are greatly reduced, which facilitates the acquisition of materials and reduces production costs.

[0044] It should be understood that all the above embodiments are illustrative rather than restrictive. Any modifications, equivalent changes and modifications made by those skilled in the art to the specific embodiments described above under the concept of the present invention are still within the scope of the technical solution of the present invention.
