[0002] Trough lamps, which use traditional energy-saving lamps as light sources, are widely used in various occasions because of their high luminous efficiency and energy-saving advantages. Troughs, also known as wiring troughs, wiring troughs, line troughs, and bridges (depending on the location), are electrical tools used to organize power lines, data lines, and other wires in a standardized manner and fix them on the wall or ceiling. The wiring inside the troughs used in traditional trough lamps is complicated. On the market, a group of wires are used for power (a group of live, neutral, and ground wires), and then power is taken from this group of wires to the lamps. It is a solution that one switch controls a group of lamps or one lamp. After such wiring is completed, it will be very complicated to readjust the plan, and the cost will be very high. In addition, this single wiring method will be more cumbersome and complicated in wall or ceiling wiring. Due to the limited load carried by a group of wires, it will lead to great restrictions on the lamps. Utility Model Content

[0024] like Figure 1-5As shown, a wire slot bridging terminal comprises a wire slot 1 which is spliced end to end with each other, a pair of bridging terminals 3 are used to bridge and transmit electricity between two of the wire slots 1, the two bridging terminals 3 are connected by a wire 4, the bridging terminals 3 are snapped into and plugged into the wire slot 1, the bridging terminal 3 comprises a bridging base 34, a bridging functional part 31 arranged on the bridging base 34, and a plurality of power supply plug-ins 32 which are evenly spaced and arranged on the bridging functional part 31 for plugging and cooperating with the wire slot 1 to draw power, two adjacent power supply plug-ins 32 form a power supply slot that cooperates with the wire slot 1, and power supply springs 33 are arranged on opposite sides of the two adjacent power supply plug-ins 32. The wire trough 1 has a downward opening for snap-fitting, and a plurality of inverted T-shaped slot plates 11 are evenly spaced at the top of the wire trough 1. Two adjacent slot plates 11 form a T-shaped slot, and corresponding T-shaped rubber strips 12 are snap-fitted in the corresponding slots. Electrically conductive copper strips 13 are embedded on both sides of the T-shaped rubber strips 12 along their length direction.
[0025] The utility model proposes a wire slot bridging terminal, which is provided with a wire slot 1, a bridging terminal 3, a bridging base 34, a bridging functional part 31, a power-taking plug-in board 32, a power-taking spring piece 33, a slot plate 11, a T-shaped rubber strip 12, and a power-transmitting copper strip 13. When in use, two bridging terminals 3 are respectively inserted into the two wire slots 1 after being connected, and the bridging terminal 3 is inserted toward the wire slot opening so that the power-taking slot is plugged and matched with the T-shaped rubber strip 12, and the power-transmitting copper strip 13 is in contact with the power-taking spring piece 33 to form conductivity, so that electricity is transmitted to another wire slot through the wire. The utility model proposes a new bridging power transmission structure, which is simple and compact in structure, easy to use and install, stable in power taking and transmission, and highly practical.
[0026] Specifically, as shown in the figure, the power-taking spring piece 33 includes an upper power-taking spring piece and a lower power-taking spring piece, and the power-transmitting copper bar 13 is correspondingly configured as an upper power-transmitting copper bar and a lower power-transmitting copper bar. When the T-shaped rubber strip 12 is inserted into the power-taking slot, the upper power-taking spring piece contacts the upper power-transmitting copper bar for power transmission, and the lower power-taking spring piece contacts the lower power-transmitting copper bar for power transmission.
[0027] It is worth mentioning that not every card slot is equipped with a T-shaped rubber strip. The user can determine the number of T-shaped rubber strips, upper power transmission copper strips, and lower power transmission copper strips according to actual needs, making assembly simple and convenient. Similarly, the settings of the upper power-taking spring sheet and the lower power-taking spring sheet can also be set according to actual needs.
[0028] Specifically, as shown in the figure, the two inner sides of the opening of the wire trough 1 are symmetrically provided with a clamping block 14, and a U-shaped structure is formed between the clamping block 14 and the wire trough 1. The two sides of the bridge base 34 are symmetrically provided with a power-taking clamping ear 35, and the power-taking clamping ear 35 is correspondingly arranged in an inverted U-shaped structure. When plugging in power, the power-taking clamping ear 35 is engaged with the clamping block 14. An integrally formed clamping arm 37 and an inclined surface 36 arranged on the outside of the clamping arm 37 are formed on the outside of the clamping arm 37. A 90-degree clamping slot is formed between the clamping arm 37 and the inclined surface 36. When plugging in power, the clamping block 14 passes through the inclined surface 36 and is clamped into the clamping slot. By setting the outer surface of the power-taking ear 35 to be a 90-degree slot structure, it can be easily inserted into the opening of the wire slot 1 and clamped with the clamping block 15. Similarly, when the lamp body needs to be disassembled, the clamping arms 37 on both sides can be clamped and applied downward force to easily remove it, which makes assembly and disassembly convenient.
[0029] Specifically, as shown in the figure, the two wire ducts 1 are butt-jointed by splicing sheet metal 2 .
[0030] Specifically, the following examples are given:
[0031] The utility model can realize wiring in the wire trough, reduce the scope and distance of wiring on the wall, and can lay 21 wires at most, divided into 10 groups of wires (live wire, neutral wire, common ground wire), and realize 10 groups of control at most (realizing 1 group of three wires to 10 groups of 21 wires selection). At the same time, after the lamps are installed, if you want to adjust the control scheme, it will be very simple, and the control scheme can be flexibly changed. The lamps can take power from any of the 4 groups of wires in the wire trough through the power terminals; for example (5 wires and 4 groups): an office is divided into 4 There are three areas (A, B, C, and D, each of which is controlled by the 1st, 2nd, 3rd, and 4th group of wires respectively. At this time, the lights in area A are powered by the 1st group of wires, the lights in area B are powered by the 2nd group of wires, the lights in area C are powered by the 3rd group of wires, and the lights in area D are powered by the 4th group of wires). The lights in each area have a separate control scheme, but if you want to control the lamps in area D and area A at the same time, you only need to plug the power cord of the lamp in area D into the 1st group of wires corresponding to the power terminal, which can be flexible and changeable.
[0032] The utility model bridges from one wire trough to another wire trough, skips the connecting sheet metal in space, makes full use of the internal space and avoids interference;
[0033] The internal spring of the wiring terminal can be changed according to the number of copper bars in the wire trough, providing customers with a variety of options;
[0034] When the number of wirings is small, the number of bridging terminals does not need to be fully filled, and the power cord does not need to be fully plugged in, so as to reduce unnecessary material waste and make the best use of resources.
[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
[0036] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
