Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a buckle connection structure of wiring terminals. Background Art

[0002] The terminal block is an accessory product used to achieve electrical connection. With the increasing degree of industrial automation and the increasingly stringent and precise requirements for industrial control, the use of terminal blocks has gradually increased, the scope of use has expanded, and the types have increased. In the prior art, in a patent document with a patent publication number of "CN112615180A", a connector socket terminal is disclosed, which includes a plug-in part, which is a box structure, an elastic contact body and an anti-over-position support structure, and the elastic contact body matches the plug terminal. During the plug-in process, the side wall of the structure is easily stuck with the plug terminal, resulting in the plug-in part being unable to be inserted or pulled out, thereby causing the current to be unable to flow smoothly due to the terminal block not being plugged in place. Utility Model Content

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that the current cannot flow smoothly due to the connection terminal not being plugged in place, thereby providing a snap-on structure of the connection terminal that can be quickly and easily plugged in place.

[0004] To this end, the utility model provides a snap-on structure of a wiring terminal, comprising an inserting portion for inserting into a plug terminal and a fixing portion for fixing a wire, the inserting portion comprising a connecting piece connected to the fixing portion and an elastic piece connected to the connecting piece to form an angle, wherein the angle is an acute angle, the elastic piece can be elastically deformed toward a side close to the connecting piece, and a contact piece for abutting against the plug terminal is further provided on the side of the connecting piece facing away from the elastic piece, and a guiding arc surface for inserting into the plug terminal is provided at a bending point between the connecting piece and the elastic piece.

[0005] Further: the elastic sheet includes a contact end arranged on one side of the connecting sheet and a bending end arranged on the other end, and a bending hook is arranged at the bending end. The bending hook is arranged in a "U"-shaped structure, and its opening direction is opposite to the connecting sheet.

[0006] Furthermore: a transition piece is provided at the connection between the connecting piece and the elastic piece, the width of the transition piece is smaller than the width of the connecting piece, and a reinforcing rib for abutting against the plug terminal is provided on the transition piece.

[0007] Further: the connecting piece is provided with an avoidance groove for avoiding the contact piece.

[0008] Furthermore: the fixing part includes a first fastening piece for fastening to the insulating shell of the wire and a second fastening piece for fastening to the core of the wire, and the height of the first fastening piece is higher than the height of the second fastening piece.

[0009] Further: a plurality of evenly distributed anti-slip strips are arranged on the inner side of the second fastener.

[0010] Further: a wrapping plate for wrapping the wire is arranged between the first fastening member and the second fastening member.

[0011] The technical solution of the utility model has the following advantages:

[0012] 1. The utility model provides a snap-on structure of a wiring terminal, in which a connecting piece and an elastic piece are arranged to form an angle with an opening upward. Since the elastic piece is arranged at an angle, the connecting piece and the elastic piece can play a guiding role when they are inserted into the plug terminal. After the connecting piece and the elastic piece are plugged into place, the socket terminal will exert an extrusion force on the elastic piece, squeezing the elastic piece toward the side close to the connecting piece until the contact piece is snapped into the plug terminal, thereby making a "ding" sound, which can prompt the operator that the wiring terminal has been snapped into place. Therefore, through the guiding setting of the connecting piece and the elastic piece themselves, the wiring terminal can be quickly snapped into the plug terminal.

[0013] 2. The utility model provides a snap-on structure for a wiring terminal, wherein the elastic sheet comprises a contact end and a bent end. When the wiring terminal is inserted into a plug terminal, due to the limited width of the insertion position of the plug terminal, the connection between the connecting sheet and the elastic sheet can easily pass through the insertion position of the plug terminal. When the connecting sheet and the elastic sheet are continuously inserted, the elastic sheet is limited by the side wall of the plug terminal, and during the continuous downward pressure, the elastic sheet will gradually deform toward one side of the connecting sheet. By setting the "U"-shaped structure of the bending hook, it can play a guiding role in the process of entering the plug terminal, so that the connecting sheet and the elastic sheet can be better inserted.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] Example

[0026] The present embodiment provides a snap-on structure of a wiring terminal, comprising an inserting portion 1 for inserting into a plug terminal and a fixing portion 2 for fixing a wire, wherein the inserting portion 1 comprises a connecting piece 11 connected to the fixing portion 2 and an elastic piece 12 connected to the connecting piece 11 to form an angle, wherein the angle is an acute angle, and the elastic piece 12 can be elastically deformed toward a side close to the connecting piece 11, and a contact piece 3 for abutting against the plug terminal is further provided on a side of the connecting piece 11 facing away from the elastic piece 12, and a guiding arc surface 4 for inserting into the plug terminal is provided at a bending portion between the connecting piece 11 and the elastic piece 12.

[0027] The above specific improvements are: Figure 1 and Figure 2 As shown, compared with the prior art, the connecting piece 11 and the elastic piece 12 are arranged to form an angle with the opening upward. Since the elastic piece 12 is arranged at an angle, the connecting piece 11 and the elastic piece 12 can play a guiding role when inserted into the plug terminal. After the connecting piece 11 and the elastic piece 12 are plugged into place, the socket terminal will have an extrusion force on the elastic piece 12, squeezing the elastic piece 12 toward the side close to the connecting piece 11 until the contact piece 3 is snapped into the plug terminal, thereby making a "ding" sound, which can prompt the operator that the terminal has been snapped into place. Therefore, through the guiding setting of the connecting piece 11 and the elastic piece 12 themselves, the terminal can be quickly snapped into the plug terminal, which is better than the prior art and can effectively avoid the problem that the terminal side wall is easily stuck with the plug terminal during the plugging process, resulting in the plug-in part 1 being unable to be inserted or pulled out, thereby causing the current to be unable to flow smoothly due to the terminal not being plugged into place.

[0028] Based on the above embodiment: the elastic sheet 12 includes a contact end 121 arranged on one side of the connecting sheet 11 and a bending end 122 arranged on the other end, and a bending hook 5 is arranged at the bending end 122, and the bending hook 5 is arranged in a "U"-shaped structure, and its opening direction is opposite to the connecting sheet 11.

[0029] The above specific improvements are: Figure 3 As shown, the elastic sheet 12 includes a contact end 121 and a bent end 122. When the wiring terminal is inserted into the plug terminal, due to the limited width of the insertion position of the plug terminal, the connection between the connecting sheet 11 and the elastic sheet 12 can easily pass through the insertion position of the plug terminal. When the connecting sheet 11 and the elastic sheet 12 are continuously inserted, the elastic sheet 12 is limited by the side wall of the plug terminal. During the continuous downward pressure, the elastic sheet 12 will gradually deform toward one side of the connecting sheet 11. By setting the "U"-shaped structure of the bending hook 5, it can play a guiding role in the process of entering the plug terminal, so that the connecting sheet 11 and the elastic sheet 12 can be better inserted.

[0030] On the basis of the above embodiment: a transition piece 6 is provided at the connection between the connecting piece 11 and the elastic piece 12 , the width of the transition piece 6 is smaller than the width of the connecting piece 11 , and a reinforcing rib 61 for abutting against the plug terminal is provided on the transition piece 6 .

[0031] On the basis of the above embodiment: the connecting piece 11 is provided with an avoidance groove 7 for avoiding the contact piece 3 .

[0032] The above specific improvements are: Figure 3 and Figure 4 As shown, by setting the transition piece 6, the connecting piece 11 and the elastic piece 12 can be connected together. By setting the reinforcing rib 61, after the connecting piece 11 and the elastic piece 12 are inserted, the friction contact force between the transition piece 6 and the plug terminal can be increased, making the connection between the two tighter.

[0033] On the basis of the above embodiment: the fixing portion 2 includes a first fastening member 21 for fastening to the insulating housing of the wire and a second fastening member 22 for fastening to the core of the wire, and the height of the first fastening member 21 is higher than the height of the second fastening member 22.

[0034] On the basis of the above embodiment: a plurality of evenly distributed anti-slip strips 8 are disposed on the inner side of the second fastening member 22 .

[0035] On the basis of the above embodiment: a wrapping plate 9 for wrapping the wire is provided between the first fastening member 21 and the second fastening member 22 .

[0036] like Figure 2 and Figure 4 As shown, the first fastener 21 is used to fasten the insulating shell of the wire, and the second fastener 22 is used to fasten the wire core. In order to increase the friction between the wire core and the second fastener 22, an anti-slip strip 8 is provided on the second fastener 22. Through the setting of the wrapping plate 9, when the wire is connected to the first fastener 21 and the second fastener 22, it can play a guiding and positioning role.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
