Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection, in particular to an anti-electric shock wiring terminal. Background Art

[0002] A terminal block is a connector used to achieve electrical connection. Some terminals are connected to the power line for power conduction, and some are connected to the signal line for signal transmission. The terminal block generally includes a terminal block and a terminal block plug connected to the terminal block. The terminal block is provided with a plug cavity, and the plug cavity is provided with a conductive terminal. After the terminal block is connected to the power supply, the conductive terminal is charged. Because the opening of the plug cavity is large, before the terminal block is plugged in, the user's fingers are easy to touch the charged conductive terminal, which is easy to cause electric shock and is not very safe to use. Summary of the invention

[0003] The purpose of the utility model is to provide an anti-electric shock terminal, which can solve the technical problems mentioned in the background technology.

[0004] In order to achieve the above-mentioned purpose, the technical scheme of the utility model is as follows: an anti-electric shock terminal, comprising a terminal seat and a terminal plug plugged into the terminal seat, one end of the terminal seat is recessed with a plug cavity, a sheet-shaped conductive terminal is provided in the middle of the plug cavity, a sheet-shaped insulating sheet is provided on the upper part of the conductive terminal, the insulating sheet is arranged perpendicular to the conductive terminal, both sides of the upper end of the conductive terminal in the length direction are exposed outside the insulating sheet and the upper end of the insulating sheet is higher than the upper end of the conductive terminal, one end of the terminal plug is protruding to form a plug part matching the plug cavity, the end of the plug part has a terminal socket, two symmetrically arranged and opposite to the terminal socket clamping tongues are provided in the plug part, and a first groove is opened downwardly and can be passed through the middle of the two clamping tongues, when the plug part is inserted into the plug cavity, the conductive terminal is inserted from the terminal socket between the clamping tongues and clamped by the clamping tongues, and the insulating sheet is placed in the first groove.

[0005] Preferably, the upper portion of the conductive terminal is provided with a second groove opening upward, and the lower portion of the insulating sheet is provided with a third groove opening downward. When the insulating sheet is mounted on the conductive terminal, the upper portion of the insulating sheet is placed in the second groove, and the lower portion of the conductive terminal is placed in the third groove.

[0006] Preferably, a protrusion is provided on the side wall of the second groove, and ribs are provided on both sides of the upper portion of the insulating sheet at positions opposite to the second groove.

[0007] Preferably, a first inclined surface is provided at the opening of the second groove, and a second inclined surface is provided at the opening of the third groove.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the conductive terminal of the utility model is provided with an insulating sheet, and the insulating sheet is higher than the conductive terminal. Even if the user's finger accidentally extends into the plug cavity, the conductive terminal will not be touched due to the blocking of the insulating sheet, thereby preventing the risk of electric shock. Because the insulating sheet does not completely cover the conductive terminal, when the terminal block and the terminal plug are plugged in, the conductive terminal is inserted between the clamping tongues, and the exposed insulating sheet portion of the conductive terminal is clamped by the clamping tongues to achieve electrical connection, and the insulating sheet is placed in the first groove of the clamping tongue, and the insulating sheet does not need to be removed, which is very convenient to use.

[0015] like Figure 1-Figure 5As shown, the utility model provides an anti-electric shock terminal, including a terminal block 1, and a terminal plug 2 plugged into the terminal block 1, one end of the terminal block 1 is recessed with a plug cavity 3, the middle of the plug cavity 3 is provided with a sheet-shaped conductive terminal 4, the upper part of the conductive terminal 4 is provided with a sheet-shaped insulating sheet 5, the insulating sheet 5 is vertically arranged with the conductive terminal 4, the upper ends of the conductive terminals 4 are exposed to the insulating sheet 5 on both sides in the length direction, and the upper end of the insulating sheet 5 is higher than the upper end of the conductive terminal 4, the terminal plug One end of the head 2 protrudes to form a plug part 6 that matches the plug cavity 3. The end of the plug part 6 has a terminal socket 7. The plug part 6 is provided with two symmetrically arranged clamping tongues 8 opposite to the terminal socket 7. The middle parts of the two clamping tongues 8 are provided with a first groove 9 that is opened downward and through which the insulating sheet 5 can pass. When the plug part 6 is inserted into the plug cavity 3, the conductive terminal 4 is inserted from the terminal socket 7 between the clamping tongues 8 and is clamped by the clamping tongues 8, and the insulating sheet 5 is placed in the first groove 9.

[0016] When the utility model is used, the plug part 6 is inserted into the plug cavity 3, the conductive terminal 4 enters between the clamping tongue pieces 8 from the terminal socket 7, the insulating piece 5 on the conductive terminal 4 is placed in the first groove 9 of the clamping tongue piece 8, and the clamping tongue piece 8 is clamped on the exposed insulating piece portion of the conductive terminal 4, so as to realize electrical connection, and the insulating piece 5 does not need to be removed, so it is very convenient to use. When the plug part 6 is taken out from the plug cavity 3, because the insulating piece 5 is arranged on the conductive terminal 4 in the plug cavity 3, and the insulating piece 5 is higher than the conductive terminal 4, even if the user's finger accidentally extends into the plug cavity 3, it will not touch the conductive terminal 4 due to the blocking of the insulating piece 5, so as to prevent the risk of electric shock.
