[0033] like Figures 1 to 4 As shown, the present invention provides a user wiring parallel groove clamp, including an upper wire clamp seat 1 and a lower wire clamp seat 2, characterized in that two external components 8 are symmetrically provided on the top of the upper wire clamp seat 1, two wire grooves 3 are symmetrically provided on opposite sides of the upper wire clamp seat 1 and the lower wire clamp seat 2, a movable pressure block 5 is movably connected to the bottom of the upper wire clamp seat 1 corresponding to the wire groove 3, and a contact component 9 is provided in the movable pressure block 5, and a fixed pressure block 6 is fixedly connected to the top of the lower wire clamp seat 2 corresponding to the wire groove 3;

[0034] The external component 8 includes a terminal block 81 and a coupling component 82 arranged at the bottom of the terminal block 81. The coupling component 82 includes a T-shaped seat 821 fixedly connected to the bottom of the terminal block 81 and one or more elastic hook plates 822 symmetrically arranged on one side of the T-shaped seat 821. A T-shaped slot 823 is provided on the upper wire clamp seat 1. A hook groove 824 is provided on one side of the T-shaped slot 823 corresponding to the elastic hook plate 822. The T-shaped seat 821 is inserted into the T-shaped slot 823, and each elastic hook plate 822 is located in the corresponding hook groove 824. A collection plate 83 is provided in the T-shaped seat 821, and one side of the collection plate 83 is connected to the contact component 9. A terminal assembly 84 is provided in the terminal block 81, and the terminal assembly 84 is connected to the other side of the collection plate 83.

[0035] The wiring assembly 84 includes one or more wiring holes 841 symmetrically arranged on the wiring seat 81 and a conductive voltage plate 842 arranged at the bottom of the corresponding wiring hole 841. The top of each wiring hole 841 is connected to a wire pressing plate 844 through a wire pressing bolt 843. One or more conductive voltage plates 842 are commonly connected to a conductive rod 845, and one or more conductive rods 845 are all connected to the assembly plate 83.

[0036] The contact assembly 9 includes a conductive slot 91 provided in the movable pressing block 5 and a connecting plate 93 connected to the conductive slot 91 via a conductive spring 92 . The connecting plate 93 is fixedly connected to a contact rod 94 , and one end of the contact rod 94 abuts against the assembly plate 83 .

[0037] A conductive protrusion 12 is formed on the assembly plate 83 , and one end of the conductive protrusion 12 passes through the middle and outer sides of the T-shaped seat 821 , and one end of the contact rod 94 abuts against the conductive protrusion 12 .

[0038] A sealing rubber pad is glued to the bottom of the T-shaped slot 823 .

[0039] A T-shaped inserting plate 13 is provided corresponding to the T-shaped slot 823 , and one side of the T-shaped inserting plate 13 is also provided with one or more elastic hook plates 822 .

[0040] A locking plate is fixedly connected to one side of the wiring seat 81. The locking plate has a through hole for the locking bolt to pass through, and a threaded hole is provided on the upper wire clamp seat 1 corresponding to the through hole.

[0041] An adjusting groove 4 is provided on the upper wire clamp seat 1 corresponding to the wire groove 3 , and the movable pressing block 5 is installed in the adjusting groove 4 through an adjusting bolt 10 .

[0042] A circuit breaker assembly 7 for controlling the on / off of the conductive circuit between the fixed pressing block 6 and the movable pressing block 5 is provided in the upper wire clamp seat 1 , and the circuit breaker assembly 7 is located between the wire slot 3 and the adjustment slot 4 .

[0043] Two sliding grooves are symmetrically provided on the upper wire clamp seat 1, and each trapezoidal seat 75 is slidably connected to the corresponding sliding groove.

[0044] What needs to be further explained in the present invention is that, when the present invention is in use, when the wire diameters of the two wires are the same, the two wires are placed in the two wire troughs 3 respectively, and then the upper wire clamp seat 1 and the lower wire clamp seat 2 are locked by the wire clamp bolts. At this time, the movable pressure block 5 and the fixed pressure block 6 are at the same distance from the bottom of the corresponding wire trough 3. After locking, the fixed pressure block 6 and the movable pressure block 5 are in contact with the two wires and tightly press the two wires. At this time, the paralleling operation of the two wires of the same wire diameter is completed, and the shapes of the movable pressure block 5 and the fixed pressure block 6 enable better clamping of the wires; when the wire diameters of the two wires are different, at this time, the position of the movable pressure block 5 is adjusted by the adjusting bolt 10 according to the size of the wire diameters, so that the distance between the movable pressure block 5 and the bottom of the corresponding wire trough 3 is different from the distance between the fixed pressure block 6 and the bottom of the wire trough 3. At this time, the paralleling of the two wires of different wire diameters can be completed by following the above operation;

[0045] When the user's electric meter is to be connected to the line, the contact rod 94 of the contact assembly 9 is pressed down to be flush with the bottom of the T-slot 823, and then the terminal block 81 is directly inserted into the T-slot 823 through the T-slot 821. The elastic hook plate 822 is elastically clamped in the corresponding hook groove 824, so that the terminal block 81 is engaged with the upper wire clamp 1, and the wire is connected to the wiring hole 841 on the terminal block 81. The wire is pressed into the wire hole 841 on the wire block 81, and the wire pressing plate 844 is pressed tightly against the conductive voltage plate 842 through the wire pressing bolt 843 to complete the connection. The conductive circuit is the wire, the conductive voltage plate 842, the collecting plate 83, the contact assembly 9 to the movable pressure block 5, so that the user's electric meter is connected to the line. There is no need to strip the insulation layer of the wire for bundling and winding the wiring, which will not leave insulation risks and the wiring is simple and efficient. Moreover, when the movable pressure block 5 is adjusted, the contact assembly can be adjusted through the conductive spring 9 2, so that the conductive rod 845 and the connecting plate 93 remain in contact with each other. When the line does not need an external wire, the elastic hook plate 822 is pressed downward from the hook groove 824 to disengage it from the hook groove 824. At this time, the terminal block 81 is pulled to one side until the external component 8 is completely out of the T-shaped slot 823, and then the T-shaped plug-in plate 13 is inserted into the T-shaped slot 823. The elastic hook plate 822 is clamped in the hook groove 824, so that the T-shaped plug-in plate 13 covers and seals the connection to prevent environmental damage to it, so as to avoid it from being unable to engage with the wiring component 84 when needed. When the external component 8 is loose and unstable after being connected by the clamping connection between the elastic hook plate 822 and the hook groove 824, a locking screw brush can be connected to the locking plate and connected to the threaded hole on the upper wire clamp seat 1 through a locking bolt to stably connect the external component 8 to the upper wire clamp seat 1.

[0046] By using the external component 8, the device can simultaneously connect multiple users with one wire clamp while meeting the branch connection requirements, and avoid the occurrence of overcurrent and heat caused by multiple users being connected to the same wiring port, eliminating potential hidden dangers.

[0047] When the line after the parallel groove clamp needs to be powered off for troubleshooting, the nylon bolt 74 is pushed forward by the thread to disconnect the trapezoidal seat 75 from the two wedge-shaped conductive plates 73. The nylon bolt 74 has good non-conductive properties, which can avoid electric shock accidents when operating the nylon bolt 74. After disconnection, the connection line between the two wires is interrupted, and because the terminal seat 81 is connected to the movable pressure block 5 for the conductive line, only the user after the parallel groove clamp is powered off, and the power supply of residents on other lines will not be affected. However, after the maintenance is completed, the nylon bolt 74 is pushed forward by the thread to disconnect the trapezoidal seat 75 from the two wedge-shaped conductive plates 73. The bolts 74 bring the trapezoidal seat 75 back into contact with the two wedge-shaped conductive plates 73, and in order to ensure a tight connection between the trapezoidal seat 75 and the wedge-shaped conductive plates 73, as well as a tight connection between the wedge-shaped conductive plates 73 and the movable pressure block 5 and the fixed pressure block 6, the wedge-shaped conductive plates 73 are configured as elastic plates with a large elastic coefficient, so that they can undergo a certain elastic deformation under the pressure of the trapezoidal seat 75, so that the trapezoidal seat 75 is in close contact with the wedge-shaped conductive plates 73, and the wedge-shaped conductive plates 73 are tightly abutted against the fixed pressure block 6 and the movable pressure block 5, thereby ensuring that the conductive circuit is unobstructed.

[0048] In order to ensure safety during wiring, a terminal 11 is provided on the upper wire clamp seat 1, which can form grounding protection after being connected to the external grounding wire, thereby improving the safety of the device. In order to facilitate use, all bolts used are hexagon socket bolts and the hexagon sockets are of the same size, so that power personnel only need to use one caliber of hexagon socket wrench, and there is no need to change to different hexagon socket wrenches. In addition, the entire device is insulated on the outside, and there is no need to install an additional insulating sleeve.

[0049] Two movable pressing blocks 5 are provided in order to apply force evenly when compressing the wire. If one movable pressing block 5 is used, the force applied on one side will be smaller due to the longer distance between the movable pressing blocks 5, and the compressing force on the wire will be insufficient. However, two movable pressing blocks 5 can apply sufficient force to the wire, and the magnitude of the applied force will not differ too much.

[0050] The movement of the trapezoidal seat 75 in the slide groove makes the movement trajectory of the trapezoidal seat 75 more stable, and reduces the impact of contact deviation with the wedge-shaped conductive plate 73.

[0051] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
