Detailed Description

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.

The present embodiment relates to a wiring device for a socket, which may be a wall socket, a mobile socket (i.e., a socket row), a track socket, or the like, and the specific form of the socket is not limited in this embodiment.

Most of the current wiring devices are screw-type wiring devices, and spring-type wiring devices exist, for example, the spring-type wiring devices are provided with spring plates, wires are inserted into the wiring devices, and the spring plates are pressed against the wires to be in contact with conductive plates of the wiring devices, so that the wiring devices are electrically connected with the wires.

However, the conventional spring-piece type wiring device is insufficient in clamping force on the wire, and poor contact between the wire and the wiring device is likely to occur.

In addition, in the current spring-piece type wiring device, in the process of inserting the wire into the wiring device, the spring piece in the wiring device is easy to move, so that the spring piece cannot press the wire.

In addition, in the conventional spring-type wiring device, the contact area between the wire and the conductive sheet in the wiring device is not large enough, which results in high contact resistance.

The embodiment provides a wiring device, which comprises an elastic reed, wherein the elastic reed is used for carrying out double pressing on a wire, so that the clamping force on the wire is increased, and good contact between the wire and the wiring device is ensured. The conducting strip of this termination clamps the wire from top to bottom, increases termination and wire's area of contact, reduces contact resistance. The elastic reed of the wiring device is positioned in the wiring device, so that the situation that the elastic reed moves when a wire is inserted into the wiring device is avoided.

The structural features of the wiring device are described in detail below.

As shown in fig. 1, the wiring device is a schematic structure of the wiring device, and the wiring device may be a positive electrode wiring device, a negative electrode wiring device, or a zero line wiring device.

Referring to fig. 1, the wiring device includes a wiring terminal 1, a conductive sheet 2, and an elastic reed 3. The material of the wiring terminal 1 is an insulating material, and is used as a fixing seat of the wiring device. The conductive sheet 2 is made of metal, such as copper sheet, and is used for electrically connecting with the wire and the plug bush of the socket. The elastic reed 3, simply called a spring piece, may be made of a metal with ductility and good fatigue resistance, such as stainless steel. The elastic reed 3 is flake-shaped and has ductility, so the elastic reed 3 has elasticity, and can still keep good elasticity after long-time use because of better fatigue resistance, thereby slowing down the failure of the elastic reed 3 and prolonging the service life of the elastic reed 3.

With continued reference to fig. 1, the terminal 1 has a cavity 13, the conductive sheet 2 and the spring reed 3 are both disposed in the cavity 13, the sidewall of the cavity 13 has a wiring opening 111, the wire 100 can extend into the cavity 13 through the wiring opening 111 to be in contact with the conductive sheet 2 to achieve electrical connection, and the spring reed 3 can urge the conductive sheet 2 to be in close contact with the wire 100 to ensure electrical connection stability.

With continued reference to fig. 1, the conductive sheet 2 includes a support arm 21 and a spring arm 22, where the support arm 21 and the spring arm 22 are connected and are disposed in opposite positions, such as the support arm 21 and the spring arm 22 are disposed up and down, to form a U-shaped structure. Since the support arm 21 and the spring arm 22 are connected and are positioned relatively, the opening 23 can be formed between them. For example, as shown in fig. 1, the supporting arm 21 and the spring arm 22 are formed in a U-shaped structure, and then the opening of the U-shape is the opening 23.

In one example, as shown in fig. 1, the position of the opening 23 is opposite to the position of the wire connection opening 111, as shown in fig. 2, which is a schematic view of the wire 100 extending into the wire connection device, and referring to fig. 2, the wire 100 extends through the wire connection opening 111 and through the opening 23 and between the support arm 21 and the spring arm 22.

In one example, the distance between the supporting arm 21 and the spring arm 22 is smaller than the diameter of the wire 100, the spring arm 22 has a certain elasticity, and the wire 100 is clamped between the supporting arm 21 and the spring arm 22, and the wire 100 is in contact with both the supporting arm 21 and the spring arm 22 to realize the electrical connection with the conductive sheet 2.

In one example, the spring reed 3 is used to strengthen the contact force between the conductive sheet 2 and the conductive wire 100, and accordingly, the spring reed 3 includes a first reed 31 and a second reed 32, as shown in fig. 1, where the first reed 31 and the second reed 32 are located on the same side of the support arm 21, such as above the support arm 21 facing the conductive wire 100. With continued reference to fig. 1, the first reed 31 and the second reed 32 are arranged back and forth in the insertion and extraction direction of the wire 100, the first reed 31 far from the wire connection port 111 is pressed against the spring arm 22, and the second reed 32 near to the wire connection port 111 is used for pressing the wire 100.

Referring to fig. 2, a first spring 31 is pressed against a spring arm 22, so that the wire 100 is firmly clamped between the support arm 21 and the spring arm 22, and a second spring 32 is pressed against the wire 100, so that the wire 100 is tightly contacted with the first support arm 21.

Since the first reed 31 and the second reed 32 are arranged in the front-back direction along the insertion direction of the wire 100, and the first reed 31 is pressed against the spring arm 22 and the second reed 32 is pressed against the wire 100, as shown in fig. 2, the length of the support arm 21 is greater than the length of the spring arm 22, where the length refers to the dimension along the insertion direction of the wire 100.

It can be seen that the portion of the wire 100 extending into the wiring device, far from the wiring port 111, is clamped between the support arm 21 and the spring arm 22, while the portion near the wiring port 111 is clamped between the second reed 32 and the support arm 21, and the wire 100 is doubly clamped in the wiring device, so that the clamping force of the wiring device to the wire 100 is improved, and good contact between the wire 100 and the wiring device is ensured.

With continued reference to fig. 2, under the action of the first spring 31, the portion of the wire 100 extending between the support arm 21 and the spring arm 22 is in contact with both the support arm 21 and the spring arm 22, and under the action of the second spring 32, the portion of the wire 100 not extending between the support arm 21 and the spring arm 22 is in contact with the support arm 21, and it can be seen that the contact area of the wire 100 with the conductive sheet 2 is large. Therefore, the wiring device can increase the contact area between the wire 100 and the conductive sheet 2, reduce the contact resistance, and further reduce the power transmission loss.

In one example, in order to further increase the contact area between the wire 100 and the conductive sheet 2, correspondingly, as shown in fig. 3, a schematic structural diagram of the conductive sheet 2 is shown, referring to fig. 3, the shape of the cross section of the support arm 21 in the direction perpendicular to the insertion direction of the wire 100 includes an arc shape, wherein the arc shape is adapted to the wire 100.

Thus, referring to fig. 12, the supporting arm 21 may wrap the conductive wire 100, thereby increasing the contact area between the conductive wire 100 and the supporting arm 21, and thus increasing the contact area between the conductive wire 100 and the conductive sheet 2.

Likewise, the shape of the cross-section of spring arm 22 in the direction perpendicular to the insertion and extraction direction of wire 100 may also include an arc shape, wherein the arc shape is adapted to wire 100.

Thus, the portion of the wire 100 extending between the support arm 21 and the spring arm 22 is covered by the support arm 21 and the spring arm 22, and the portion of the wire 100 not extending between the support arm 21 and the spring arm 22 is covered by the support arm 21, so that the contact area between the wire 100 and the conductive sheet 2 can be increased.

In one example, the wire 100 can be prevented from falling off the wire connection device by increasing the clamping force of the wire 100 in the wire connection device, and accordingly, in order to further prevent the wire 100 from falling off, as shown in fig. 2, the support arm 21 includes a horizontal section 211 and an inclined section 212, where the horizontal section 211 is close to the wire connection port 111, and the inclined section 212 is tilted relative to the horizontal section 211 in a direction close to the first reed 31, or the inclined section 212 is tilted relative to the horizontal section 211 in a direction away from the first reed 31, so that an included angle between the inclined section 212 and the horizontal section 211 is an obtuse angle.

As shown in fig. 2, the inclined section 212 is inclined relative to the horizontal section 211, so as to avoid the wire 100 from falling off from between the support arm 21 and the spring arm 22, and further avoid the wire 100 from falling off from the wiring device.

It should be noted that the inclined section 212 may be inclined toward the inner surface of the wire 100, or may be inclined toward the inner surface of the wire 100 and the outer surface facing away from the wire 100. The present embodiment does not limit how the inclined section 212 is inclined, and it is sufficient that the inclined section 212 causes the wire 100 to tilt or bend.

As described above, the cross-sectional shape of the support arm 21 includes an arc shape, and the cross-sectional shapes of the horizontal section 211 and the inclined section 212 may each include an arc shape, or the cross-sectional shape of the horizontal section 211 may include an arc shape as described with reference to fig. 3.

In an example, the clamping between the conductive sheet 2 and the conductive wire 100 may be further enhanced by increasing the contact friction between the conductive sheet 2 and the conductive wire 100 to avoid the conductive wire 100 from falling off, and correspondingly, as shown in fig. 3, the inner surface of the supporting arm 21 facing the conductive wire 100 may be provided with a plurality of strip grooves 213, where the strips of the strip grooves 213 are perpendicular to the inserting and extracting direction of the conductive wire 100, and the plurality of strip grooves 213 are sequentially arranged along the inserting and extracting direction of the conductive wire 100.

In one example, the inner surface of the supporting arm 21 has a plurality of strip grooves 213, so that the inner surface of the supporting arm 21 forms uneven ribs, which can increase the roughness of the inner surface of the supporting arm 21, further increase the static friction between the supporting arm 21 and the wire 100, and further avoid the wire 100 from falling off.

As described above, the support arm 21 may include the horizontal section 211 and the inclined section 212, and then, both the horizontal section 211 and the inclined section 212 may have the strip-shaped groove 213, or, as shown in fig. 3, the horizontal section 211 may have the strip-shaped groove 213, which is not limited in this embodiment, and the horizontal section 211 may have the strip-shaped groove 213 as shown in the drawing.

Also, the inner surface of the spring arm 22 facing the wire 100 may also have a plurality of strip grooves 213 as described above to increase the roughness of the inner surface of the spring arm 22.

In one example, the clamping force of the wire 100 by the wire connection device can be further improved by increasing the contact area between the first reed 31 and the spring arm 22 and/or increasing the contact area between the second reed 32 and the wire 100, so as to avoid loosening of the wire 100 in the wire connection device.

Accordingly, as shown in fig. 2, the first reed 31 has a first abutment piece 311, wherein the first abutment piece 311 is a portion near the end of the first reed 31, and the first abutment piece 311 abuts in parallel on the spring arm 22 when the wire 100 is clamped between the support arm 21 and the spring arm 22.

For example, the length of the first abutment piece 311 may be equivalent to the length of the spring arm 22, and referring to fig. 2, the first abutment piece 311 abuts on the abutment section 221 of the spring arm 22, and then the length of the first abutment piece 311 may be equivalent to the length of the abutment section 221. The contact area between the first contact piece 311 and the spring arm 22 is relatively large, so that the contact section 211 of the spring arm 22 can be brought into contact with the wire 100 at each position.

With continued reference to fig. 2, the second reed 32 has a second abutment piece 321, wherein the second abutment piece 321 is a portion near an end of the second reed 32, the second abutment piece 321 is parallel to a wire insertion and extraction direction for abutting against the wire 100, and the second abutment piece 321 is parallel to abutting against the wire 100 when the wire 100 is clamped in the wiring device.

In one example, to pass the wire 100 through the opening 23 and between the support arm 21 and the spring arm 22, and correspondingly, with continued reference to fig. 3, the spring arm 22 includes an abutment section 221 and a guide section 222, wherein the guide section 222 is adjacent to the wire connection port 111 and is bent away from the support arm 21 relative to the abutment section 221, the first reed 31 is pressed against the abutment section 221, and the opening 23 is formed between the guide section 222 and the support arm 21.

Thus, even though the distance between the support arm 21 and the spring arm 22 is smaller than the diameter of the wire 100, the wire 100 is relatively easy to enter between the support arm 21 and the spring arm 22 and is clamped between the support arm 21 and the spring arm 22 due to the guide section 222 at the opening 23.

Similarly, in order to make the lead 100 relatively easy to extend between the second reed 32 and the support arm 21, correspondingly, referring to fig. 2, the second reed 32 is bent or curved, and the distance between the second reed 32 and the support arm 21 gradually decreases from the direction approaching the wire connection port 111 to the direction separating the wire connection port 111.

That is, the distance between the second reed 32 and the support arm 21 is relatively large near the junction 111, so that the wire 100 is relatively easy to pass through the junction 111, enter between the second reed 32 and the support arm 21, gradually decrease as the wire 100 continues to extend into, and further the second contact piece 321 of the second reed 32 contacts the wire 100.

In one example, to facilitate withdrawal of the wire, i.e., to facilitate withdrawal of the wire from the wiring device, a portion of the guide section 222 near the end, as shown in fig. 4, may also be positioned above the second reed 32 opposite the support arm 21.

Thus, when the wire is required to be withdrawn, a technician can use a tool to extend into the wiring device through the wiring port 111 to push the second reed 32, the second reed 32 is lifted, the wire 100 is not pressed any more, the guide section 222 is lifted during the lifting of the second reed 32, and the distance between the support arm 21 and the spring arm 22 is increased, at this time, the technician can easily pull out the wire 100 without damaging the wire 100.

In another example, as shown in fig. 5, the guide section 222 may also include a guide piece 2221 and a withdrawal piece 2222. The guide piece 2221 is connected to the contact section 221, and is bent in a direction away from the support arm 21 with respect to the contact section 221, whereby the opening 23 is formed between the guide piece 2221 and the support arm 21.

With continued reference to fig. 5, the wire withdrawing piece 2222 is connected to the guide piece 2221, and is bent in a direction toward the support arm 21 with respect to the guide piece 2221, and a portion of the wire withdrawing piece 2222 near the end is located above the second spring piece 32 facing away from the support arm 21.

Thus, as shown in fig. 6, when the wire is to be withdrawn, the technician uses a tool to push the second reed 32 through the wire connection port 111, and the second reed 32 is lifted away from the wire 100, and does not press the wire 100. Meanwhile, the second reed 32 will also lift the wire withdrawing piece 2222, the distance between the spring arm 22 and the support arm 21 increases in the process of lifting the wire withdrawing piece 2222, and in addition, the connection part between the wire withdrawing piece 2222 and the guide piece 2221 will also push the first reed 31 to lift, so that the first reed 31 no longer presses the abutting section 221 of the spring arm 22.

In one example, as shown in fig. 6, the wire withdrawing piece 2222 is bent in a direction approaching the support arm 21 with respect to the guide piece 2221, and a portion of the wire withdrawing piece 2222 approaching an end portion is bent in a direction separating from the support arm 21, so that the guide piece 2221 is connected to the wire withdrawing piece 2222 to form an S-like structure.

With continued reference to fig. 6, the portion of the wire withdrawing piece 2222 near the end is bent in a direction away from the support arm 21, so that the second spring piece 32 is relatively easy to lift the wire withdrawing piece 2222 in a direction away from the wire 100.

In one example, a technician can use a tool directly to push second reed 32 to perform the wire-withdrawal operation. Alternatively, in another example, as shown in fig. 7, the wiring device may also include a wire withdrawing block 4, the wire withdrawing block 4 being located in the chamber 13 below the second reed 32 facing the support arm 21, the wire withdrawing block 4 being for pushing the second reed 32.

As described above, the second reed 32 is curved or bent, and then, as shown in fig. 7, the upper surface of the wire withdrawing block 4 facing the second reed 32 is inclined to be in better contact with the second reed 32, thereby pushing the second reed 32.

In order to avoid interference of the wire withdrawing block 4 with insertion of the wire 100, correspondingly, a lower surface of the wire withdrawing block 4 facing the supporting arm 21 is an inclined surface, and an included angle between the inclined surface and the insertion direction of the wire 100 is an acute angle. Thus, the lower surface of the wire withdrawing block 4 is inclined along the insertion direction of the wire 100, so that the wire 100 does not interfere with the insertion of the wire 100 when the wire 100 is inserted into the wiring device.

In order for a technician to use a tool, the wire withdrawing block 4 is pushed through the wire connection port 111, and accordingly, the inclined surface of the wire withdrawing block 4 is positioned opposite to the wire connection port 111 and exposed through the wire connection port 111. Thus, as shown in fig. 7, when the wire is to be withdrawn, the technician uses a tool, passes through the wire connection port 111, enters the wire connection device, pushes the wire withdrawal block 4, the wire withdrawal block 4 pushes the second spring piece 32, and the second spring piece 32 is lifted away from the support arm 21, so that the wire 100 is not pressed any more. Meanwhile, the second reed 32 will also lift the wire withdrawing piece 2222, the distance between the spring arm 22 and the support arm 21 increases in the process of lifting the wire withdrawing piece 2222, and in addition, the connection part between the wire withdrawing piece 2222 and the guide piece 2221 will also push the first reed 31 to lift, so that the first reed 31 no longer presses the abutting section 221 of the spring arm 22. At this time, the technician can withdraw the wire 100 from the wiring device relatively easily, and it can be seen that the wire 100 is not damaged during withdrawal from the wiring device.

In one example, to prevent the wire 100 from moving when inserted into the wiring device, the spring reed 3 is correspondingly clamped in the cavity 13 of the wiring terminal 1 as shown in fig. 8, for example, the spring reed 3 has a limiting hole 33 (not shown in fig. 8 and see fig. 13), and the cavity 13 has a limiting block 112, where the limiting block 112 is clamped in the limiting hole 33. The elastic reed 3 is clamped in the cavity 13, so that the elastic reed 3 can be prevented from shaking or moving when the wire 100 is inserted into the wiring device, the first reed 31 can always press the elastic arm 22, and the second reed 32 can press the wire 100.

It should be noted that, the elastic reed 3 may have a stopper, and the cavity 13 may have a stopper hole, which is not limited in the arrangement of the stopper and the stopper hole, but the stopper hole may be disposed on the elastic reed, and the stopper is disposed in the cavity 13 for illustration.

The specific structural features of the terminal 1, the conductive sheet 2 and the spring reed 3 will be described below, respectively.

Before describing the features of the individual structures, the features of the wiring device are first described.

The wiring device can be connected with two wires externally, so that the wiring device has a jumper function, and then, as shown in fig. 9, the wiring device is an exploded schematic view of the wiring device capable of connecting two wires, and the wiring device comprises two wiring ports 111, two conductive sheets 2 and two elastic reeds 3. Wherein the two conductive sheets 2 and the two spring leaves 3 share a chamber 13.

Since the two conductive sheets 2 have an electrical connection relationship, as shown in fig. 9, the two conductive sheets 2 may be integrally formed into one conductive sheet 2, so the conductive sheet 2 may include two sets of the support arms 21 and the spring arms 22 described above, that is, the conductive sheet 2 includes two support arms 21 and two spring arms 22, the support arms 21 and the spring arms 22 are in one-to-one correspondence, and the two support arms 21 are connected by the connecting piece 24 (see fig. 10 and 11).

Wherein, the two elastic reeds 3 can be mutually independent, and the elasticity of the two reeds is not affected. The two connection ports 111 may also be independent of each other and have a certain distance therebetween, so as to avoid the short circuit phenomenon caused by interconnection of the two connected wires.

Thus, the wiring port 111, the spring reed 3, and the set of the support arm 21 and the spring arm 22 of the conductive sheet 2 are in one-to-one correspondence, for example, one wiring port 111 corresponds to the set of the support arm 21 and the spring arm 22, and the set of the support arm 21 and the spring arm 22 corresponds to one spring reed 3.

The jumper function of the wiring device is described below, for example, in which one power conductor extends from the wall, and the user wants to install a plurality of wall switches, such as three wall switches, respectively designated as a 1# wall switch, a 2# wall switch, and a 3# wall switch, on the wall. In this scenario, the power conductor may be connected to one of the ports of the 1# wall switch, while the other port of the 1# wall switch may be connected to another conductor (commonly referred to as a jumper conductor), and the other end of the jumper conductor may be connected to one of the ports of the 2# wall switch, so that the 1# wall switch is connected to the 2# wall switch through the jumper conductor. Likewise, another jumper wire may be connected between the other connection port of the 2# wall switch and one connection port of the 3# wall switch.

Thus, the 1# wall switch is directly electrically connected to the power supply wire, the 2# wall switch is electrically connected to the power supply wire through the 1# wall switch, and the 3# wall switch is electrically connected to the power supply wire through the 1# wall switch and the 2# wall switch.

The above-mentioned wiring function of the wiring device is referred to as a jumper function of the wiring device.

The structural features of the terminal 1 are described below.

As shown in fig. 9, the inner surface of the front seat 11 facing the rear seat 12 has a first protrusion 113 protruding toward the cavity 13, and the stopper 112 may be disposed on the upper surface of the first protrusion 113.

It should be noted that, as shown in fig. 9, since the number of the elastic reed 3 is two, the number of the first protrusions 113 is two, and the stopper 112 on one first protrusion 113 is used for stopping one elastic reed 3, and the stopper 112 on the other first protrusion 113 is used for stopping the other elastic reed 3.

As shown in fig. 9, the wire connection port 111 may be provided on a rear sidewall 121 of the rear seat 12 facing the front seat 11. Such as two wire connection openings 111, are provided on a rear side wall 121 of the rear seat 12 facing the front seat 11.

As described above, the number of the elastic reeds 3 is two, and thus the number of the second reeds 32 is two, so that the number of the second protrusions 122 is also two, one for abutting one second reed 32 and the other for abutting the other second reed 32.

As shown in fig. 9, the rear sidewall 121 of the rear seat 12 may further have third protrusions 123 protruding toward the cavity 13, for example, the number of the third protrusions 123 is two, the two third protrusions 123 are arranged along a direction perpendicular to the insertion and extraction direction of the wire 100, the wire connection port 111 is located between the two third protrusions 123, and the wire withdrawal block 4 is placed on the two third protrusions 123.

As described above, the lower surface of the wire withdrawing block 4 facing the wire 100 is a slope, so as shown in fig. 9 and referring to fig. 8, the surface of the third bump 123 facing the wire withdrawing block 4 is also a slope, and the slope of the third bump 123 is the same as the slope of the lower surface of the wire withdrawing block 4.

As described above, the number of the wiring ports 111 is two, and then the number of the third protrusions 123 is four, wherein two of them are located at both sides of one wiring port 111 and the other two are located at both sides of the other wiring port 111.

The above is the structural feature of the connection terminal 1, and the structural feature of the conductive sheet 2 is described below.

As described above, the conductive sheet 2 includes two sets of support arms 21 and spring arms 22, and connects the two support arms 21 electrically, so, as shown in fig. 10, a structural feature of the conductive sheet 2 is shown, the conductive sheet 2 includes two support arms 21, two spring arms 22 and one connecting piece 24, the connecting piece 24 is connected between the two support arms 21, and there is a space between the two spring arms 22, and the two spring arms 22 are independent of each other, so that the two spring arms 22 do not affect each other, one spring arm 22 is located above (e.g. directly above) one support arm 21, and the other spring arm 22 is located above (e.g. directly above) the other support arm 21.

As shown in fig. 11, another structural feature of the conductive sheet 2 is that the conductive sheet 2 has a U-shape, including a bottom sheet 201, a top sheet 202, and a vertical sheet 203 connected between the bottom sheet 201 and the top sheet 202.

As shown in fig. 11, the bottom piece 201 is used to form two support arms 21 and a connecting piece 24, and the inner wall of the vertical piece 203 extends into the U-shaped space of the U-shaped conductive piece 2 to form two spring arms 22, one spring arm 22 is located above one support arm 21, and the other spring arm 22 is located above the other support arm 21.

As shown in fig. 12 and referring to fig. 11, the conductive sheet 2 is installed in the chamber 13, the top sheet 202 of the conductive sheet 2 is attached to the top wall of the chamber 13, the vertical sheet 203 of the conductive sheet 2 is attached to the front side wall of the chamber 13, and the bottom sheet 201 of the conductive sheet 2 is located at the bottom wall of the chamber 13, so that the conductive sheet 2 is fitted in the chamber 13.

With continued reference to fig. 12, since the first spring 31 of the spring 3 presses the spring arm 22, the spring 3 is located in the U-shaped space of the U-shaped conductive sheet 2. Since the inner wall of the cavity 13 has the first bump 113, as shown in fig. 11, the vertical piece 203 of the conductive piece 2 has the avoiding opening 2031, and the first bump 113 passes through the avoiding opening 2031 and extends into the U-shaped space of the U-shaped conductive piece 2 to be engaged with the elastic reed 3 in the space.

The above is the structural feature of the conductive sheet 2, and the structural feature of the elastic reed 3 is described below.

As described above, the number of the elastic reeds 3 is two, and the structural characteristics of the two elastic reeds 3 are the same, so the structural characteristics of one of the elastic reeds 3 will be described below.

As shown in fig. 13, the elastic reed 3 is schematically shown, and the first reed 31 and the second reed 32 are integrally formed and can be bent and deformed by the U-shaped elastic reed. For example, the elastic reed 3 includes a first transverse sheet 301 and a second transverse sheet 302, the length of the first transverse sheet 301 is smaller than that of the second transverse sheet 302, the first transverse sheet 301 and the second transverse sheet 302 are bent towards the same side to form a first reed 31 and a second reed 32 respectively, wherein the first reed 31 forms a first acute angle with an unbent body portion of the first transverse sheet 301, the second reed 32 forms a second acute angle with an unbent body portion of the second transverse sheet 302, and the first acute angle is smaller than the second acute angle.

As described above, the elastic reed 3 has the stopper hole 33, and the stopper hole 33 may be disposed on the first lateral piece 301, or, as shown in fig. 13, the stopper hole 33 may be disposed at the junction between the first lateral piece 301 and the vertical piece connecting the first lateral piece 301 and the second lateral piece 302, and then, a part of the stopper hole 33 is located on the vertical piece of the elastic reed 3 and another part is located on the first lateral piece 301. Thus, referring to fig. 12, in the front seat 11 of the terminal 1 gradually approaching the rear seat 12, the stopper 112 can gradually slide into the stopper hole 33, and when the front seat 11 is fixed to the rear seat 12, the stopper 112 is caught in the stopper hole 33. It can be seen that, one part of the limiting hole 33 is located on the first transverse piece 301, and the other part is located on the vertical piece connecting the first transverse piece 301 and the second transverse piece 302, so that the limiting block 112 is clamped into the limiting hole 33 in the assembly of the wiring device, the assembly is simplified, and the assembly efficiency is improved.

For other structural features of the first reed 31 and the second reed 32, see the above description, and will not be repeated here.

Referring to fig. 12, the spring reed 3 is fitted in the U-shaped space of the U-shaped conductive sheet 2, and the unbent body portion of the first lateral sheet 301 is supported by the first bump 113. Since the first bump 113 has the stopper 112 thereon, the stopper hole 33 of the spring reed 3 is disposed on the unbent body portion of the first lateral piece 301.

With continued reference to fig. 12, the vertical portion of the spring reed 3 connecting the first and second lateral pieces 301 and 302 abuts against the vertical piece 203 of the conductive piece 2, and the bent portion of the second lateral piece 302 of the spring reed 3 abuts against the rear side wall 122 of the chamber 13.

With continued reference to fig. 12, the second spring 32 of the elastic spring 3 abuts against the second bump 122 and the wire withdrawing block 4, and the second spring 32 may not abut against the wire withdrawing block 4, for example, a gap is formed therebetween.

The above is a structural feature of the spring reed 3, and an assembling process of the wiring device will be described.

For example, the spring reed 3 may be first fitted in the U-shaped space of the U-shaped conductive sheet 2, the spring reed 3 fitted in the conductive sheet 2 being in a compressed state. As shown in fig. 14, the upper surface of the unbent portion of the second transverse sheet 302 of the elastic reed 3 is tightly attached to the inner surface of the top sheet 202 of the conductive sheet 2, the outer surface of the vertical portion of the elastic reed 3 is tightly attached to the inner surface of the vertical sheet 203 of the conductive sheet 2, the first abutting sheet 311 of the first reed 31 abuts against the abutting section 221 of the spring arm 22, and the second abutting sheet 321 of the second reed 32 may abut against the supporting arm 21, may contact with the supporting arm 21 only, or may be suspended above the supporting arm 21.

Since the spring reed 3 is compressed in the U-shaped space of the conductive sheet 2, the spring reed 3 is not easily detached from the U-shaped space of the conductive sheet 2 during assembly.

Then, the wire withdrawing block 4 may be placed between the second bump 122 and the third bump 123 of the rear seat 12, as shown with reference to fig. 12.

Then, the assembly of the conductive sheet 2 and the elastic reed 3 may be assembled in the rear seat 12, and then the first bump 113 of the front seat 11 slides along the unbent portion of the second lateral sheet 302 of the elastic reed 3 to be fixed with the rear seat 12, and the stopper 112 provided on the front seat 11 is clamped into the stopper hole 33 of the elastic reed 3 to complete the stopper of the elastic reed 3 during the sliding of the front seat 11 to the rear seat 12.

The above-described assembly process of the wiring device is by way of example only and is not limiting.

For example, the socket is a wall socket, or a rail socket, and the wires are power wires extending from the inside of the wall. The socket is a mobile socket, and then the wires are wires extending from the socket box.

As described above, referring to fig. 12, the wire passes through the connection port of the connection device, extends between the support arm and the spring arm, and is clamped between the support arm and the spring arm, and between the second reed and the support arm.

The wiring device of the socket comprises a conducting strip and an elastic reed, wherein the conducting strip comprises a supporting arm and an elastic arm, the elastic reed comprises a first reed and a second reed, a wire penetrates through a wiring port of the wiring device and stretches into the space between the supporting arm and the elastic arm, the supporting arm and the elastic arm clamp the wire, the first reed is propped against the elastic arm, the wire stretches into the space between the supporting arm and the elastic arm, the wire is further clamped between the supporting arm and the elastic arm, and the second reed is propped against the wire which does not stretch into the space between the supporting arm and the elastic arm. It can be seen that the first reed and the spring arm double-clamp the same position of the wire, and the first reed and the second reed double-clamp different positions of the wire.
