Description

Technical Field

[0001] The utility model relates to the technical field of wiring, in particular to a wiring structure and a plug and a power connector applying the wiring structure. Background Art

[0002] Power connectors are essential components in electronic devices, connecting two active devices to transmit current or signals. They are used in LED streetlights, LED driver power supplies, LED displays, lighthouses, cruise ships, industrial equipment, broadcasting, television, and communications. Power connectors include plugs, receptacles that connect to plugs, or two plugs that connect to each other. Plugs consist of metal parts that conduct electricity through contact with external wires.

[0003] Currently, power connectors on the market often use a screw-type locking wire connection method to connect metal parts and external wires. For example, the Chinese utility model patent with authorization number CN219246982U discloses a "three-plug structure" and the Chinese utility model patent with authorization number CN221379929U discloses an "anti-spark plug."

[0004] However, this screw-locked wiring method is cumbersome, complicated, time-consuming and labor-intensive to operate. Utility Model Content

[0005] The first technical problem to be solved by the present invention is to provide a wiring structure that is easy for users to operate in view of the current status of the existing technology.

[0006] The first technical problem to be solved by the utility model is to provide a plug.

[0007] The first technical problem to be solved by the utility model is to provide a power connector.

[0008] The technical solution adopted by the present invention to solve the above-mentioned first technical problem is as follows: a wiring structure includes a housing having an installation cavity;

[0009] a metal part, disposed in the mounting cavity;

[0010] It is characterized by: it also includes

[0011] The locking unit is arranged in the installation cavity; each locking unit includes

[0012] an elastic member disposed in the mounting cavity; the elastic member is bent at a first position to be divided into a first action arm and a second action arm that are elastically connected, the first action arm being located in front of the second action arm, the free end of the first action arm being denoted as the first end, and the free end of the second action arm being denoted as the second end;

[0013] Under the action of external force, the elastic member has at least two states;

[0014] In the first state, the middle portion of the first actuating arm and the middle portion of the second actuating arm are locked, the first end is positioned higher than the second end, and the first actuating arm and the second actuating arm tend to be disengaged;

[0015] In the second state, the first end is pushed forward by the external wire inserted into the installation cavity, so that the first action arm and the second action arm are disengaged, and the second end is used to press the external wire against the metal member.

[0016] In order to limit the position of the elastic member, the locking unit further includes a limiting member fixed relative to the cavity wall of the installation cavity, the first action arm and the second action arm are locked to form an accommodating space for the limiting member to be inserted, and the elastic member is constrained on the limiting member. In this way, the elastic member is limited by providing the limiting member.

[0017] In order to save labor in operation, a hollow portion is provided on the first action arm near the position where the first action arm contacts the limiting member.

[0018] In this way, the solid part of the first action arm at the location of the hollow part is smaller, which is convenient for rotation. The user only needs to insert the external wire forward with a little force, and the external wire can rotate the first action arm and disengage from the second action arm, which saves the user effort.

[0019] In order to limit the first operating arm, the cavity wall of the installation cavity or the metal part is provided with a bulge between the hollow portion and the first position. The bulge protrudes toward the first operating arm, and the first operating arm is constrained between the bulge and the limiting member.

[0020] In this way, the first action arm rotates with the corresponding positions of the limiting member and the convex hull as the fulcrum.

[0021] In order to reduce the assembly process, the limiting member and the cavity wall of the installation cavity are integrated;

[0022] Alternatively, the limiting component and the metal component are an integral part.

[0023] The structure of the limiting member can be various. Preferably, there are two limiting members, which are respectively recorded as the first limiting block and the second limiting block;

[0024] The first action arm is fixed between the first limiting block and the cavity wall corresponding to the installation cavity, and the second action arm is fixed between the second limiting block and the cavity wall corresponding to the installation cavity;

[0025] Alternatively, the first action arm is fixed between the first limiting block and the corresponding position of the metal component, and the second action arm is fixed between the second limiting block and the corresponding position of the metal component.

[0026] The elastic member is limited by providing a first limiting block and a second limiting block.

[0027] The locking structure between the first and second actuating arms can be implemented in a variety of ways. Preferably, the first actuating arm has a rearwardly extending hook in the middle, and the second actuating arm has a locking portion in the middle that engages and locks with the hook. The hook and the locking portion are less susceptible to wear, which helps extend the service life of the elastic member.

[0028] Alternatively, existing structures such as rib-groove snap-fit structures and magnetic attraction may be used to achieve locking of the two.

[0029] In order to facilitate the removal of the external wire, the locking unit further includes an unlocking member movably arranged in the installation cavity, the unlocking member is exposed outside the housing and cooperates with the second action arm of the elastic member;

[0030] In the third state, the unlocking member is subjected to a forward external force and pushes the second operating arm forward, thereby locking the second operating arm with the first operating arm, and at the same time, the second end is disengaged forward from the external wire.

[0031] By providing an unlocking member, external force acts on the unlocking member to push the second action arm close to the first action arm, and the second end is disengaged from the external wire, so that the external wire can be removed.

[0032] In order to prevent the unlocking member from falling off from the housing, the unlocking member has an anti-falling portion that abuts against the inner wall surface of the installation cavity wall in the front and rear directions.

[0033] In order to prevent the elastic member from interfering with the unlocking member, the middle portion of the first operating arm has a hook extending backward, and the middle portion of the second operating arm has a clamping portion locked with the hook;

[0034] There are two hooks, which are spaced apart in the left-right direction. The anti-slip portion is opposite to the position between the two hooks. The unlocking member is provided with avoidance spaces on both sides of the anti-slip portion for avoiding the corresponding hooks.

[0035] In this way, by providing the avoidance space, interference between the elastic member and the unlocking member is avoided.

[0036] In order to reasonably utilize the space in the housing, there are at least two locking units, which are distributed in the installation cavity at intervals along the circumference of the housing. In this way, the layout is reasonable and the space in the housing can be fully utilized.

[0037] In order to facilitate the installation of external wires, the connector also includes an end cover arranged at the rear end of the shell, the front end of the end cover is threadedly connected to the shell, and the rear end of the end cover is for the external wires to pass through.

[0038] During installation, firstly insert the external wire into the shell and abut against the second action arm of the elastic member, and finally connect the end cover to the shell by thread.

[0039] Furthermore, the connector includes the external wire.

[0040] The technical solution adopted by the present invention to solve the second technical problem is: a plug, characterized in that it includes the connector as described above.

[0041] The technical solution adopted by the present invention to solve the third technical problem is: a power connector, characterized by comprising the above-mentioned plug and a socket mated with the plug;

[0042] Alternatively, it comprises two plugs that are plugged into each other, at least one of which is the above-mentioned plug.

[0043] Compared with the prior art, the advantages of the present invention are: by setting an elastic part, when installing the external wire, the external wire is inserted into the installation cavity to complete the quick connection with the metal part, which is convenient for users to operate. Specifically, the first end of the elastic part is pushed forward by the external wire, so that the first acting arm and the second acting arm are disengaged, and the second end of the second acting arm presses the external wire against the metal part. The user can even complete the installation of the external wire with bare hands without using any tools. The structure is simple and reasonable. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0065] Example 1

[0066] See also Figures 1 to 16 The wiring structure includes a housing 1, a metal member 2, an external wire 100, a locking unit 300, and an end cover 200.

[0067] Among them, see Figure 1 、 Figure 7 、 Figure 14The housing 1 is made of insulating plastic and has a mounting cavity 11. The housing 1 comprises an outer shell 1a and a mounting seat 1b arranged in the outer shell 1a.

[0068] The metal component 2 is disposed in the mounting cavity 11 , specifically on the mounting seat 1 b .

[0069] See also Figure 2 、 Figure 8 , Figure 15 、 Figure 16 The locking unit 300 is arranged in the installation cavity 11, and the locking unit 300 has three ( Figure 15 、 Figure 16 ) and are spaced apart along the circumference of the housing 1 within the mounting cavity 11. The number of external wires 100 is the same as the number of locking units 300, also three. The three external wires are finally combined into a large strand and passed through the end cap 200. Each locking unit 300 includes an elastic member 3, a limiting member 4, and an unlocking member 5. The specific structure is as follows.

[0070] See also Figure 4 、 Figure 5 , the elastic member 3 is arranged in the mounting cavity 11; the elastic member 3 is sheet-shaped, and in the first position 3a ( Figure 4 、 Figure 5 ) is bent and divided into a first action arm 31 and a second action arm 32 that are elastically connected. The elastic connection means that after the elastic member 1 is bent, the first action arm 31 and the second action arm 32 always maintain a tendency to open relative to each other by relying on the elastic force of the elastic member 3 itself. The first action arm 31 is located in front of the second action arm 32. The free end of the first action arm 31 is recorded as the first end 31a, and the free end of the second action arm 32 is recorded as the second end 32a. Under the action of external force, the elastic member 3 has three states. In the first state, the middle part of the first action arm 31 and the middle part of the second action arm 32 are locked ( Figure 5 ), the first end 31a is located higher than the second end 32a, and the first action arm 31 and the second action arm 32 tend to be disengaged; in the second state, the first end 31a is pushed forward by the external wire 100 inserted into the installation cavity 11, so that the first action arm 31 and the second action arm 32 are disengaged ( Figure 4), the second end 32a is used to press the external wire 100 against the metal part 2; in the third state, the second action arm 32 is subjected to a forward external force and is locked with the first action arm 31, while the second end 32a is disengaged from the external wire 100 forward. The middle portion of the first action arm 31 has a hook 311 extending backward, and the middle portion of the second action arm 32 has a locking portion 321 that is locked with the hook 311, that is, the external wire 100 is locked or disengaged through the hook 311 and the locking portion 321. The elastic member 3 is made of metal and is in contact with the metal part 2. In this way, in addition to directly contacting the metal part 2, the external wire 100 is also indirectly in contact with the metal part 2 through the elastic member 3, which is beneficial to increase the contact points of the external wire 100 and ensure the electrical connection effect of the external wire 100.

[0071] See also Figure 2 、 Figure 3 、 Figures 7 to 13 The limiting member 4 is fixed relative to the cavity wall of the installation cavity 11. Specifically, the limiting member 4 is fixed to the metal member 2. The first action arm 31 and the second action arm 32 are locked to form an accommodating space 34 for the limiting member 4 to be inserted, and the elastic member 3 is constrained on the limiting member 4. The first action arm 31 is provided with a hollow portion 33 near the position where it contacts the limiting member 4. The metal member 2 is provided with a convex bulge 21 ( Figure 2 、 Figure 7 ), the convex 21 and the metal part 2 are an integral part, the convex 21 protrudes toward the first action arm 31, and the first action arm 31 is constrained between the convex 21 and the limiting member 4.

[0072] See also Figure 2 、 Figure 3 、 Figures 6 to 13 The unlocking member 5 is movably disposed in the mounting cavity 11. The unlocking member 5 is exposed to the housing 1 and cooperates with the second operating arm 32 of the elastic member 3. In the third state, the unlocking member 5 is subjected to a forward external force and pushes the second operating arm 32 forward, thereby locking the second operating arm 32 with the first operating arm 31. At the same time, the second end 32a is disengaged from the external wire 100. The unlocking member 5 has an anti-slip portion 51 that abuts against the inner wall of the mounting cavity 11 in front and back. In this way, when the unlocking member 5 is subjected to the backward elastic force of the second operating arm 32, the unlocking member 5 will not slip out of the housing 1. There are two hooks 311, which are spaced apart in the left and right directions. The anti-slip portion 51 is opposite to the position between the two hooks 311. The unlocking member 5 is provided with an escape space 52 on both sides of the anti-slip portion 51 for circumventing the corresponding hook 311. The rear end of the unlocking member 5 has a slot 53 that is recessed forward, and the slot 53 is for inserting and positioning hardware tools such as screwdrivers. The user drives the unlocking member 5 forward by acting on the hardware tool, thereby driving the second action arm 32 to rotate forward.

[0073] See also Figure 1 、 Figure 7 、 Figure 14 The end cover 200 is arranged at the rear end of the housing 1, the front end of the end cover 200 is threadedly connected to the housing 1, and the rear end of the end cover 200 is for the external wire 100 to pass through.

[0074] See also Figure 1 、 Figure 7 、 Figure 14 , the utility model includes a plug with a wiring structure, and the plug also includes a wire clamp 1c ( Figure 14 ), etc., and metal member 2 is a current carrier. This embodiment also discloses a power connector, comprising the aforementioned plug and a socket that mates with the plug, the socket generally having a rectangular mounting panel on its periphery; or, the power connector comprises two mutually pluggable plugs, at least one of which is the aforementioned plug, i.e., a male plug and a female plug.
