TECHNICAL FIELD

[0001] The present application relates to the field of electrical devices, in particular to an electrical tapping unit. BACKGROUND

[0002] In the prior art, the traditional decoration wiring form makes the socket hole position relatively fixed. If the electrical appliances with a long connection distance need to be connected, a plurality of sockets must be connected to the external electrical appliances through the power supply line of the wiring board from the wall socket, and the power supply line of the wiring board is very messy and has safety hazards. In addition, if more socket holes are arranged at the common position, the wiring in the wall will become complex, and it is difficult to accurately predict the appropriate socket hole arrangement position during decoration wiring.

[0003] Therefore, the power track and the matching electrical tapping unit are developed. The power track is electrically connected with the socket arranged on the wall through the long conductor arranged in the cavity of the power track, and can be arranged to the appropriate power taking point through the installation along the wall. The electrical tapping unit can be inserted into the cavity of the power track at any position and rotated to connect the circuit to realize the conduction connection, which is very flexible to use.

DETAILED DESCRIPTION

[0031] In order to make the technical solutions and advantages of the present application more clear, the following will combine the drawings to make a further detailed description of the disclosed embodiments of the present application.

[0032] Best Mode for Carrying Out the Invention

[0033] Referring to Figure 1 , the present embodiment is to provide a control 1 outside the upper socket 2 of the electrical tapping unit. The shape of the control 1 is not necessarily as shown in Figure 2 , which is cylindrical, but can also be square tube or other shapes. The control 1 can be repeatedly moved axially between an initial position closest to the lower base 3 and an end position farthest from the lower base 3.

[0034] Referring to Figure 2 , Figure 4 , Figure 5 , the electrical tapping unit is internally provided with a switching device. The switching device of the present embodiment mainly includes a swing plunger 15, a bracket 16, a swing arm 19, a C-shaped slot 20, a first support arm 21, a second support arm 22, and an electrical contact 23. The bracket 16 is a hollow body fixed on the base of the electrical tapping unit. The upper end of the swing plunger 15 is rotatably connected to the bracket through a pivot 14. The lower end of the swing plunger 15 is in contact with the swing arm 19. The swing arm 19 is made of an electrically conductive material and can swing in response to the swing of the swing plunger 15. The front end of the swing arm 19 is provided with an electrical contact 23. The internal connector of the electrical tapping unit is provided with a metal connecting element 17 corresponding to the position of the electrical contact 23. The first support arm 21 is also an electrically conductive body connected to the internal conductor of the base, serving as the swing support point of the swing arm 19. The second support arm 22 is connected to the base, serving as the initial position support point of the swing arm 19. When the swing arm 19 swings under the drive of the swing plunger 15, the first position is set as the disengagement of the electrical contact 23 from the connecting element 17, and the second position is set as the combination of the electrical contact 23 with the connecting element 17. The swing plunger 15 has a transverse C-shaped slot 20 in the middle rear part.Figure 3 A horizontal bar 18 is arranged on the inner wall of the control member 1 at the position corresponding to the C-shaped slot 20 as a actuating device, which can extend into the C-shaped slot 20 of the swing plunger 15; through the axial movement of the control member 1, the horizontal bar 18 can drive the electrical contact 23 at the front end of the swing arm 19 to disengage or engage with the connecting element 17.

[0035] In order to limit the axial movement of the control member 1 outside the upper socket 2 of the electrical tapping unit, the embodiment is provided with a limiting structure inside the electrical tapping unit.

[0036] In combination with Figure 3 , Figure 4 , Figure 5 , the lower base 3 includes a base and a base cover, and a rotating arm is arranged at the lower part of the base for inserting into the power rail to draw power, and the connector on the base is in conductive connection with the rotating arm. The limiting structure of the embodiment is that two first swing arms 11 are integrally formed in the base, and two second swing arms 12 are separately formed in the base. The inner wall of the control member 1 is provided with two first swing arm end clamping grooves 113 at the positions corresponding to the ends of the two first swing arms 11, and the ends 111 of the first swing arms 11 are rotatably connected in the first swing arm end clamping grooves 113; the other ends of the first swing arms 11 are matched with the first swing arm height limiting blocks 112 in the base. One end of the second swing arm 12 is rotatably connected to the second swing arm clamping groove 122 in the base, and the two second swing arm ends 121 are matched with the second swing arm end limiting sliding grooves 123 in the inner wall of the control member 1. When the control member 1 moves axially from the initial position to the end position, the first swing arm end 111 moves together with the control member 1 because it is connected to the inner wall of the control member 1, and the other end of the first swing arm 11 is limited in height by the height limiting block 112 in the base, thereby controlling the movable stroke of the control member 1; with the movement of the control member 1, the second swing arm end 121 slides in the limiting sliding groove 123 in the inner wall of the control member 1, but the slidable length is limited by the limiting sliding groove 123, thereby also controlling the movable stroke of the control member 1. The two first swing arms 11 and the two second swing arms 12 are arranged in a cross shape, so that the entire limiting structure is evenly stressed and relatively stable. The embodiment adopts two first swing arms 11 integrally formed, and a clamping protrusion 125 is arranged in the middle of the first swing arms 11, which is in interference fit with the protrusion 124 on the base, so that the first swing arm 11 has a certain supporting force on the control member 1 when the control member 1 moves to the end position, and a certain force needs to be applied to move the control member 1 to the initial position, thereby avoiding accidental touch.

[0037] As Figure 6As shown is the perspective view of the base cover of the embodiment, which is made of an insulator, and the first limiting column 8 and the second limiting column 9 are symmetrically arranged on the base cover, the first limiting column 8 and the second limiting column 9 are inverted L column bodies, and the base is respectively provided with two arc-shaped hollows 7 at positions corresponding to the first limiting column 8 and the second limiting column 9. For reference, see Figure 3 The first limiting block 4 and the second limiting block 5 are arranged on the inner wall of the control member 1 at positions corresponding to the two arc-shaped hollows 7 of the base. When the control member 1 is assembled with the base and the base cover, the control member 1 is mounted on the base, the first limiting block 4 and the second limiting block 5 of the inner wall of the control member 1 are arranged on the arc-shaped hollows 7 of the base, the first limiting column 8 and the second limiting column 9 of the base cover pass through the two arc-shaped hollows 7, the column bodies of the first limiting column 8 and the second limiting column 9 are pressed on the arc surfaces of the first limiting block 4 and the second limiting block 5 and can be limited to rotate along the arc surfaces, so that the base cover can be limited to rotate along the base.

[0038] The working process of the embodiment is as follows:

[0039] After the electric tapping unit is inserted into the power track, the rotating arm of the lower base 3 is connected with the inner conductor of the power track through rotation. At this time, the control member 1 is in the initial position, i.e., the position closest to the lower base 3, and the electric contact 23 at the front end of the swing arm 19 of the switch device inside the electric tapping unit is in the disconnected state with the connecting element 17; when the control member 1 is manually moved to the terminal position, i.e., the position farthest from the lower base 3, the movement of the control member 1 causes the swing arm 19 to respond to swing, and the electric contact 23 is connected with the connecting element 17, thereby realizing the conductive state. When the control member 1 is moved to the initial position again, the swing arm 19 is forced to respond to swing, and the electric contact 23 is disconnected with the connecting element 17.

[0040] The above is only for the convenience of those skilled in the art to understand the technical solutions disclosed in the present application, and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
