Electrical appliances such as electric kettles, sterilizers, kettles or electric frying pans are typically electrically connected to the electrical appliance base through couplers. The connection mode of the coupler and the power line is usually a terminal plugging mode, and then the terminal is protected by a protective sleeve.

Fig. 1 is a schematic diagram of a coupler in the related art.

For example, referring to fig. 1, in the related art, the coupler 10 of the electric appliance needs to be connected with three electrodes 210, and the three electrodes 210 are L-phase, N-phase and ground-phase of the power line, respectively. The electrode 210 is typically a metal spring, and the connection end of the metal spring and the power cord is made into a single insert. In general, the single insert has two specifications of 0.5mm and 0.8mm, but the copper metal spring sheet only needs about 0.3mm, so that the copper sheet with the thickness of 0.25mm needs to be folded and overlapped, pressed into 0.5mm, and the production process is relatively complex.

In addition, in the assembly process of the electric appliance, the connecting end of the power line is riveted with the terminals, and then the three terminals of the power line are inserted into the inserting pieces of the coupler 10, so that the connection between the power line and the coupler 10 is realized. On one hand, terminal plugging is difficult to realize automation, and the production efficiency is low; on the other hand, after the terminals are plugged, the connection failure of the power line and the coupler 10 caused by the falling easily occurs in the axial direction of the terminals, and even the problem of loud sparking or spark occurs, so that the use safety of the electric appliance is affected.

In an embodiment of the present utility model, the fixing portion 110 may be one end of the connection terminal 100. In a specific arrangement, referring to fig. 2, a fixing hole 111 may be formed in the fixing portion 110, and the fixing portion 110 may be fixedly connected to a threaded post on the coupler 20 by a connecting member such as a bolt, a screw, or a screw passing through the fixing hole 111. That is, in the embodiment of the present utility model, the fixing portion 110 is mainly used for connecting with the coupler body 200, so as to ensure the electrical conduction between the power line and the coupler body 200.

It is understood that in the embodiment of the present utility model, the connection portion 120 may be the other end of the connection terminal 100. That is, the connection part 120 is connected to one end of the fixing part 110. When specifically provided, the connection portion 120 may be provided with a wire groove 121, and the wire groove 121 is used for mounting a wire (not shown).

It should be noted that, in the embodiment of the present utility model, the whole of the connection terminal 100 may be formed by bending a sheet metal part, and therefore, the connection groove 121 may be a groove formed by bending two sides of the sheet metal part. In addition, in the embodiment of the present utility model, the conductive wire may refer to a power line. Of course, in some examples, the connection terminal 100 may be connected to other wires, and the other wires are connected to the power line.

In the embodiment of the present utility model, it is also understood that the wire is riveted by using the side wall of the wire connection groove 121. Compared with the mode of riveting the terminal on the power line firstly and then plugging the power line of the riveting terminal with the plugging sheet on the coupler 20 in the related art, in the embodiment of the utility model, the wiring terminal 100 is directly made into a sheet metal part, one end of the wiring terminal 100 is bent to form the wiring groove 121, and the side wall of the wiring groove 121 is riveted with the power line, so that the plugging procedure of the riveting terminal with the plugging sheet on the coupler 20 is saved, the whole connecting process can realize automatic production, and the connecting efficiency of the power line and the coupler 20 is improved.

It should be noted that, in the embodiment of the present utility model, the abutting piece 122 is disposed on the inner wall of the connecting slot.

In a specific arrangement, the abutment member 122 may be detachably disposed on the inner wall of the wire-connecting slot 121, for example, in some examples, a hole may be formed on a side wall of the wire-connecting slot 121, and the abutment member 122 may penetrate through the hole and protrude from the inner wall of the wire-connecting slot 121. Like this, when the lateral wall of wiring groove 121 presss from both sides tightly, hugs tightly or rivets the wire, the piece 122 of supporting can support the wire tightly, can reduce the clearance between wire and the wiring groove 121 inner wall, promotes the inseparable degree of contact between wire and the wiring groove 121 inner wall to can effectively guarantee the stability that the wire is connected with binding post 100, avoided the condition emergence that the wire drops from binding post 100.

In other alternative examples of the embodiment of the present utility model, the abutting piece 122 may be inserted into the wire connecting slot 121 along the axial direction of the wire connecting slot 121 during the process of clamping the wire connecting slot 121, for example, inserting a part such as a thin iron wire, a rod, a needle, etc. into the wire connecting slot 121, and gradually abutting the wire against and tightly abutting the wire connecting slot 121 during the process of gradually clamping, holding or riveting the wire connecting slot 121.

In some possible examples, the abutment member 122 may also be adhesively attached to the inner wall of the wiring trough 121.

In addition, in the embodiment of the present utility model, by providing the wire connection groove 121 on the connection portion 120, the abutting member 122 protrudes from the inner wall of the wire connection groove 121; thus, when the wire is mounted to the wiring groove 121, the wire can be mounted into the wiring groove 121 from the notch of the wiring groove 121 in the radial direction or the depth direction of the wiring groove 121, that is, the wire can be simultaneously mounted into the wiring groove 121 in the whole axial direction of the wiring groove 121. That is, in the embodiment of the present utility model, by arranging the wiring groove 121 at the connection portion 120 and protruding the abutting piece 122 at the inner wall of the wiring groove 121, compared with the related art, the convenience of wire installation and connection is improved, the wire installation is convenient in place, and the yield of products is improved.

That is, in the embodiment of the present utility model, the abutting piece 122 may be specifically disposed at the bottom wall of the wiring groove 121, or the abutting piece 122 may be disposed at the side of the side wall of the wiring groove 121 facing the bottom wall.

In the embodiment of the utility model, the abutting piece 122 protrudes out of the bottom wall of the wire connecting groove 121. In this way, the blocking/obstructing effect of the abutting piece 122 on the wire on the side wall of the wiring groove 121 can be reduced, lowered or weakened, so that the convenience of installing the wire into the wiring groove 121 is improved, the wire is convenient to install in place, and the yield of products is improved.

In addition, it is also understood that in the embodiment of the present utility model, the abutting piece 122 may also protrude from the side wall of the wiring groove 121. When specifically provided, the abutment member 122 may be provided on only one of the side walls of the wiring duct 121, or in other alternative examples, the abutment member 122 may be provided on both side walls of the wiring duct 121. It should be noted that, when the abutting pieces 122 are disposed on the side walls of the two sides of the wire connecting slot 121, the abutting pieces 122 on the two side walls may be disposed in a staggered manner. Alternatively, the abutting pieces 122 on the two side walls are arranged opposite to each other, but a gap for the wires to pass through is arranged between the abutting pieces 122 on the two side walls.

In some alternative examples of embodiments of the utility model, the abutment 122 may be a boss, bump, ball bump or the like within the wiring trough 121.

In other specific examples, a clamping groove may be formed on the inner wall of the wiring groove 121, the propping member 122 is clamped in the clamping groove, and the propping member 122 protrudes out of the inner wall of the wiring groove 121.

Like this, with the setting of support piece 122 in wiring groove 121, can avoid the lateral wall of wiring groove 121 to hold tightly, press into or after riveting the wire, support piece 122 takes place to drop, drop or lose the condition, can remain the validity that support piece 122 supported the wire all the time to the stability that wire and binding post 100 are connected has been guaranteed.

As a specific example of the embodiment of the present utility model, the abutting piece 122 is fixedly connected with the wiring groove 121.

Specifically, in the embodiment of the present utility model, the abutting piece 122 may be fixedly connected with the inner wall of the wiring slot 121 in a welding manner; of course, in some possible examples, the abutting member 122 may be fixedly connected to the inner wall of the wire-connecting groove 121 by a screw, a bolt, or a connecting portion 120 of a screw.

In the embodiment of the utility model, in the process of using, installing or connecting the wires, the situation that the propping piece 122 is lost can be prevented, and the effective propping of the propping piece 122 to the wires can be ensured, so that the fastening degree of the enclasping of the wires after the side wall of the wiring groove 121 is enclasped is ensured, namely the stability of the connection of the wiring terminal 100 and the wires is ensured, and the situation that the wires fall off can be avoided.

In an alternative example of the embodiment of the present utility model, the abutting piece 122 may be integrally formed with the wiring groove 121. For example, the wiring groove 121 is formed by punching or bending at a protruding portion provided on the sheet metal member, and thus the protruding portion is bent into the wiring groove 121, thereby being integrally formed with the wiring groove 121.

In one specific example of an embodiment of the present utility model, the abutment 122 is a conductive metal piece. In this way, good electrical conductivity after the wire is connected to the terminal 100 can be ensured. Specifically, in the embodiment of the utility model, the conductive metal piece can be an iron sheet, an aluminum sheet or a copper sheet; in some possible examples, the conductive metal piece may also be a spring piece. It will be appreciated that in some alternative examples, the conductive metal member may also be a metal member made of an alloy material such as an aluminum alloy, stainless steel, or the like.

That is, in the embodiment of the present utility model, the abutting member 122 may be disposed in the wiring groove 121 in a sheet-like structure.

Like this, when the propping piece 122 is propped against the wire, because the two sides of the propping piece 122 (specifically, two sides along the axial direction of the wire connecting slot 121) have hollowed-out parts, the propping piece 122 can prop against the wire to form a bending state, and the bending part of the wire can form a limit with the propping piece 122, so that the stability of the connection between the wire and the wiring terminal 100 can be improved, and the falling situation of the wire can be avoided.

It will be appreciated that in some alternative examples of embodiments of the utility model, the dimension of the abutment 122 in the axial direction of the wiring duct 121 may also be equal to the length of the wiring duct 121.

With continued reference to fig. 3, 5 and 6, in an alternative example of the embodiment of the present utility model, the number of the abutting pieces 122 is plural, and the plural abutting pieces 122 are arranged at intervals along the axial direction of the wiring groove 121.

Specifically, in the embodiment of the present utility model, the number of the abutments 122 may be 1, 2, 3 or more; the number of the abutments 122 in the drawings of the embodiment of the present utility model is 3 as a specific example.

It is understood that in the embodiment of the present utility model, the plurality of abutments 122 may be disposed on the bottom wall of the wiring trough 121. Of course, in some examples, the plurality of abutments 122 may be staggered on the bottom and side walls of the wiring trough 121. For example, the number of the abutments 122 is 3 as an example.
