Technical Field
[0001] This application relates to the field of electrical technology, and in particular to a wiring assembly and electrical device. Background Technology
[0002] A power socket, also known as a power outlet or switch socket, is an essential electrical appliance in work and daily life. Sockets typically have terminals inside, which are used to secure and connect external wires to the socket's wiring, ensuring a smooth flow of current from the power source to the socket, and thus ensuring the socket can supply power to electrical devices.
[0003] There are various types of terminal blocks, such as spring-loaded terminal blocks, which use the elasticity of a spring to clamp the lead wire. The wiring process for spring-loaded terminal blocks is relatively simple. However, the position of the spring in current spring-loaded terminal blocks is unstable and prone to shifting, which can cause the terminal block to fail to stably clamp the lead wire. Utility Model Content
[0004] In view of this, embodiments of this application provide a wiring assembly and electrical device that can prevent the elastic element from moving relative to the terminal block, thereby improving the stability of the wiring assembly in holding the lead wire.
[0005] This application provides a wiring assembly, which includes a terminal block and an elastic element located within the terminal block;
[0006] The terminal block has a first clamping arm, and the first clamping arm is provided with a slot;
[0007] The elastic element is used to clamp the lead wire in the terminal block, and the elastic element has an abutment arm that engages with the slot.
[0008] Optionally, the elastic element includes a connecting arm and two spring pieces respectively connected to the connecting arm;
[0009] The two spring pieces are arranged side by side, and a first opening is formed between the two spring pieces and the connecting arm;
[0010] The abutting arm is connected to the connecting arm and extends toward the slot within the first opening.
[0011] Optionally, the terminal block has a contact arm that intersects with the first clamping arm, the elastic member abuts against the contact arm on the side facing the contact arm, and the end face of the abutting arm away from the connecting arm abuts against the groove wall of the slot facing the contact arm.
[0012] Optionally, the spring has a first fixed arm and a second fixed arm connected together, and the connecting arm is connected to the first fixed arm of each of the two springs respectively;
[0013] The surface of the first fixing arm facing the first clamping arm abuts against the inner surface of the first clamping arm;
[0014] The surface of the second fixing arm facing the contact arm abuts against the inner surface of the contact arm.
[0015] Optionally, the spring has a first elastic arm and a second elastic arm, the first elastic arm being connected to the end of the first fixed arm away from the second fixed arm, and the second elastic arm being located between the first elastic arm and the contact arm;
[0016] The terminal block has a second clamping arm connected to the end of the contact arm that is away from the first clamping arm, and the second clamping arm is opposite to the first clamping arm;
[0017] Wherein, a portion of the lead wire is clamped between the inner surfaces of the first elastic arm and the second clamping arm, and another portion of the lead wire extending through the first elastic arm is clamped between the inner surfaces of the second elastic arm and the second clamping arm.
[0018] Optionally, the wiring assembly further includes a spacer located between the second elastic arms of the two springs, the spacer being used to separate the leads held by the two springs respectively;

[0020] Optionally, the contact arm is provided with a mounting hole, and the spacer extends into the terminal block through the mounting hole, wherein the spacer is adapted to connect to the inner wall of the mounting housing where the wiring assembly is located; or,
[0021] One end of the partition is connected to the inner surface of the contact arm, and the partition extends away from the contact arm.
[0022] Optionally, the wiring assembly has a push block, a portion of which extends into the terminal block, the push block being used for translational movement relative to the terminal block between a first position and a second position;
[0023] When the push block is in the first position, the elastic element and the terminal block clamp the lead wire; when the push block is moved to the second position, the push block presses against the elastic element to release the lead wire.

[0049] Combination Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, this application embodiment provides a wiring assembly 1, which includes a terminal block 11 and an elastic member 12 located within the terminal block 11. It should be noted that both the terminal block 11 and the elastic member 12 in this application embodiment are conductive, and for example, they can both be made of metal.
[0050] The terminal block 11 has a first clamping arm 111, which has a slot 1111. An elastic member 12 is used to clamp the lead wire within the terminal block 11, thereby allowing the current from the lead wire to be conducted to the wiring assembly 1. It should be noted that, in this embodiment, the lead wire can be, for example, a neutral wire, a live wire, or a ground wire. The elastic member 12 has an abutment arm 121, which engages with the slot 1111. It should be noted that, by utilizing the engagement of the abutment arm 121 and the slot 1111, when the elastic member 12 is assembled into the terminal block 11, it can prevent the elastic member 12 from shifting relative to the terminal block 11, thereby improving the stability of the lead wire clamping in the wiring assembly 1.
[0051] The following is in conjunction with the appendix Figures 1 to 9 The details and functions of the wiring assembly 1 provided in the embodiments of this application will be described in more detail.
[0052] Combination Figure 3 , Figure 4 and Figure 5As shown, in some embodiments, the elastic member 12 includes a connecting arm 122 and two spring pieces 123 respectively connected to the connecting arm 122. The two spring pieces 123 are arranged side by side, and a first opening 124 is formed between the two spring pieces 123 and the connecting arm 122. An abutment arm 121 is connected to the connecting arm 122 and extends toward the slot 1111 within the first opening 124. It should be noted that each spring piece 123 corresponds to a lead wire, and each spring piece 123 is used to clamp the corresponding lead wire with the terminal block 11. Since the abutment arm 121 is located in the first opening 124 between the two spring pieces 123, when the abutment arm 121 engages with the slot 1111, it can ensure that the forces on both sides of the elastic member 12 are balanced, thereby further improving the stability of the elastic member 12 after assembly with the terminal block 11.
[0053] Combination Figure 5 and Figure 6 As shown, in some embodiments, the terminal block 11 has a contact arm 112 intersecting with the first clamping arm 111. The elastic member 12 abuts against the contact arm 112 on the side facing the contact arm 112, and the end face of the abutting arm 121 away from the connecting arm 122 abuts against the groove wall of the slot 1111 facing the contact arm 112. It should be noted that when assembling the elastic member 12 with the wiring assembly, the elastic member 12 generally moves from the end of the first clamping arm 111 away from the contact arm 112 toward the contact arm 112 into the terminal block 11. Since the end face of the abutting arm 121 away from the connecting arm 122 abuts against the groove wall of the slot 1111 facing the contact arm 112, the elastic member 12 can be reverse-clamped in the opposite direction to the assembly direction X, thereby improving the effect of preventing the elastic member 12 from moving relative to the terminal block 11 in the opposite direction to the assembly direction X into the terminal block 11. Meanwhile, during the insertion and removal of the lead wire, the elastic element 12 is prevented from shifting relative to the terminal block 11 due to the force of the lead wire. It should be noted that in the wire-connected state, the end face of the lead wire can abut against the inner surface of the contact arm 112. In the wire-removed state, the lead wire is pulled out of the wiring assembly 1 and disengaged from the wiring assembly 1.
[0054] like Figure 6As shown, in some embodiments, the spring 123 has a first fixing arm 1231 and a second fixing arm 1232 connected together, and a connecting arm 122 is connected to the first fixing arms 1231 of the two springs 123 respectively. The surface of the first fixing arm 1231 facing the first clamping arm 111 abuts against the inner surface of the first clamping arm 111. The surface of the second fixing arm 1232 facing the contact arm 112 abuts against the inner surface of the contact arm 112. It should be noted that since both the first fixing arm 1231 and the second fixing arm 1232 are in surface contact with the inner surface of the terminal block 11, the contact area between the elastic member 12 and the terminal block 11 can be increased. Thus, the terminal block 11 can more securely limit the elastic member 12, prevent the elastic member 12 from shifting, and also improve the stability of the lead clamping of the wiring assembly 1.
[0055] Combination Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the spring 123 has a first elastic arm 1233 and a second elastic arm 1234. The first elastic arm 1233 is connected to the end of the first fixed arm 1231 away from the second fixed arm 1232, and the second elastic arm 1234 is located between the first elastic arm 1233 and the contact arm 112. The terminal block 11 has a second clamping arm 113 connected to the end of the contact arm 112 away from the first clamping arm 111, and the second clamping arm 113 is opposite to the first clamping arm 111. A portion of the lead is clamped between the inner surfaces of the first elastic arm 1233 and the second clamping arm 113, and another portion of the lead extending through the first elastic arm 1233 is clamped between the inner surface of the second elastic arm 1234 and the second clamping arm 113. It should be noted that using two elastic arms to clamp different parts of the same lead can improve the stability of the lead clamping, thereby ensuring good contact between the lead and the second clamping arm 113, and ensuring the stability of the current.
[0056] Combination Figure 6 , Figure 7 , Figure 8 and Figure 9As shown, in some embodiments, the wiring assembly 1 further includes a spacer 13 located between the second elastic arms 1234 of the two spring contacts 123. The spacer 13 is used to separate the leads held by the two spring contacts 123 respectively. The length of the spacer 13 extending into the terminal block 11 is not less than the distance between the contact position of the second elastic arm 1234 and the lead and the contact arm 112. It should be noted that the spacer 13 can limit the lead on both sides, preventing the lead on both sides of the spacer 13 from detaching from the position between the spring contact 123 and the second clamping arm 113 due to left-right swaying or displacement. This prevents poor contact such as intermittent connection or no contact between the lead and the wiring assembly 1, ensuring current stability and improving the reliability of the wiring assembly 1. The length of the spacer 13 extending into the terminal block 11 refers to the distance between the end face of the spacer 13 facing away from the contact arm 112 and the inner surface of the contact arm 112. Figure 6 The dimension H marked in the figure represents the distance between the contact point of the second elastic arm 1234 and the lead wire and the contact arm 112. This configuration ensures that the portion of the lead wire held by the second elastic arm 1234 will not shift left or right and disengage from the corresponding second elastic arm 1234 and the second clamping arm 113. This ensures that the entire lead wire will not experience poor contact with the wiring assembly 1 due to disengagement from the corresponding spring 123 and the second clamping arm 113, thus ensuring stable clamping of the lead wire and current stability. In some embodiments, the distance between the two side surfaces of the spacer 13 and the corresponding second elastic arm 1234 is smaller than the diameter of the lead wire. This ensures that even with slight shifting of the lead wire, it will not disengage from the second elastic arm 1234 and the second clamping arm 113, i.e., the lead wire will not disengage from the spring 123 and the terminal block 11, thereby ensuring good contact between the lead wire and the wiring assembly 1.
[0057] Combination Figure 7 and Figure 8 As shown, in some embodiments, the contact arm 112 is provided with a mounting hole 1121, and the spacer 13 extends into the terminal block 11 through the mounting hole 1121. The spacer 13 is adapted to connect with the inner wall of the mounting housing 2 where the wiring assembly 1 is located. With this configuration, when assembling the wiring assembly 1 into the housing 2, the mounting position of the wiring assembly 1 can be quickly positioned using the cooperation between the spacer 13 and the mounting hole 1121, thereby improving the assembly efficiency and accuracy of the wiring assembly 1. Alternatively, one end of the spacer 13 is connected to the inner surface of the contact arm 112, and the spacer 13 extends away from the contact arm 112. It should be noted that the spacer 13 and the contact arm 112 can be an integrally formed structure. This configuration improves the processing efficiency and assembly efficiency of the wiring assembly 1 itself, and also improves the assembly efficiency of assembling the wiring assembly 1 into the housing 2.
[0058] Combination Figure 3 and Figure 4 As shown, in some embodiments, the wiring assembly 1 has a push block 14, a portion of which extends into the terminal block 11. The push block 14 is used for translational movement relative to the terminal block 11 between a first position and a second position. When the push block 14 is in the first position, the elastic member 12 clamps the lead wire with the terminal block 11. When the push block 14 is translated to the second position, the push block 14 presses against the elastic member 12 to release the lead wire. It should be noted that during the process of the push block 14 translating from the first position to the second position, the push block 14 abuts against and pushes the first elastic arms 1233 of the two spring pieces 123, causing both first elastic arms 1233 to bend away from the second clamping arm 113. The two second elastic arms 1234 are also pushed away from the second clamping arm 113 by the corresponding first elastic arms 1233, thereby allowing the two spring pieces 123 to release the clamping force on the corresponding lead wires respectively, thus releasing the lead wires and facilitating their removal from the terminal block 11 for wire unloading.
[0059] Combination Figure 1 and Figure 2 As shown, on the other hand, this application embodiment also provides an electrical device, which includes a housing 2 and a wiring assembly 1 as described in any of the above embodiments of this application, located in the housing 2. It should be noted that the composition and function of the wiring assembly 1 in the electrical device provided in this application embodiment are the same as those in the above embodiments of this application, and therefore will not be repeated here. Since the wiring assembly 1 can stably clamp the lead wire, the electrical device with the wiring assembly 1 installed can stably clamp the lead wire. In some embodiments, the spacer 13 can be connected to the inner wall of the housing 2 facing the wiring assembly 1. Therefore, when assembling the wiring assembly 1 in the housing 2, the spacer 13 facilitates the positioning of the wiring assembly 1, thereby improving the assembly efficiency of the wiring assembly 1 and the housing 2. In some embodiments, the electrical device is a socket or a switch or a socket with an integrated switch.
[0060] like Figure 2As shown, in some embodiments, the housing 2 of the electrical device is equipped with multiple sockets, including an L-pole socket 301, an N-pole socket 302, or an E-pole socket 303. The housing 2 of the electrical device is also equipped with multiple sets of wiring assemblies 1, namely an L-pole wiring assembly 101, an N-pole wiring assembly 102, and an E-pole wiring assembly 103. The terminal block 11 of the L-pole wiring assembly 101 is connected to the L-pole socket 301, the terminal block 11 of the N-pole wiring assembly 102 is connected to the N-pole wiring assembly 102, and the terminal block 11 of the E-pole wiring assembly 103 is connected to the E-pole socket 303. Thus, when the lead wire is clamped between the terminal block 11 and the elastic member 12, an electrical connection can be established between the lead wire, the corresponding terminal block 11, and the corresponding socket. The lead wire current can then be directed to the pin of the plug that is inserted into the socket to supply power to the electrical equipment connected to the plug. It should be noted that the socket can be connected to the first clamping arm 111, the second clamping arm 113, or the contact arm 112 of the corresponding terminal block 11, thereby realizing the electrical connection between the wiring assembly 1 and the corresponding socket. It should be understood that this application... Figures 6 to 9 The diagram uses the E-pole socket 303 and the corresponding E-connection assembly 103 as an example. The assembly principle of the L-pole connection assembly 101 and the L-pole socket 301, as well as the assembly principle of the N-pole connection assembly 102 and the N-pole socket 302, are the same as the assembly principle of the E-pole connection assembly and the E-pole socket 303. The positional relationship between the socket and the corresponding connection assembly can be adjusted according to requirements.
[0061] like Figure 2 As shown, in some embodiments, the housing 2 has a wiring hole 21 for inserting a lead wire and an operation hole 22 for inserting a pusher fixture and pushing the pusher block 14. The number of wiring holes 21, the number of operation holes 22, and the positions of the wiring holes 21 and operation holes 22 can be set as needed. The housing 2 also has a pin hole 23 for inserting a pin, and the position and number of pin holes 23 can be set as needed. It should be understood that the housing 2 has a snap-fit rear shell 24 and a front panel 25, with the wiring holes 21 and operation holes 22 disposed on the rear shell 24, and the pin holes 23 disposed on the front panel 25. The accompanying drawings illustrate an example where the rear shell 24 has operation holes 22 respectively corresponding to the pusher block 14 of the L-pole wiring assembly 101, the pusher block 14 of the N-pole wiring assembly 102, and the pusher block 14 of the E-pole wiring assembly 103, with two wiring holes 21 arranged side by side below each operation hole 22, and the front panel 25 has five pin holes 23.
[0062] As can be seen from the above, the electrical device provided in this application embodiment can stably clamp the lead wire and ensure the stability of current transmission.
