Description

Technical Field

[0001] The utility model relates to the technical field of tungsten lamp power supplies, in particular to a multi-channel output tungsten lamp power supply with an interface protection function. Background Art

[0002] Tungsten lamps are usually powered by tungsten lamp power supplies to ensure the normal operation of the bulb. Tungsten lamp power supplies can provide stable current output, thereby ensuring the brightness and life of the bulb under different working conditions. In order to improve work efficiency, most of the current tungsten lamp power supplies can have multiple outputs;

[0003] When using a tungsten lamp power supply, its output end needs to be connected to the input end through a wire. Currently, most of the connection methods are only direct connection with a wire, and there is a lack of protection for the connection between the wire and the tungsten lamp power supply. After long-term use, dust will accumulate on the output end of the tungsten lamp power supply, making the connection between the wire and the tungsten lamp power supply at risk of short circuit, and the wire may fall off from the output end of the tungsten lamp power supply due to collision, which is not convenient for the normal use of the tungsten lamp power supply.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a multi-channel output tungsten lamp power supply with an interface protection function, comprising a tungsten lamp power supply body 1, a power interface 2 is fixedly arranged on the tungsten lamp power supply body 1, a line support mechanism is arranged on the power interface 2, the line support mechanism comprises a connecting arm 3, a limit seat 4, a baffle 5 and a dust cover 6, two connecting arms 3 are respectively fixedly arranged on both sides of the power interface 2, a plurality of limit seats 4 are rotatably arranged between the two connecting arms 3, the baffle 5 is vertically movably arranged on the surface of the limit seat 4 through an elastic component, the baffle 5 and the limit seat 4 are fixed to the line through a limit structure, the dust cover 6 is rotatably arranged on the two connecting arms 3, and one side of the dust cover 6 is detachably connected to the surface of the tungsten lamp power supply body 1, the surface of the dust cover 6 is embedded with a magnetic strip 15, and one side of the dust cover 6 is adsorbed and fixed to the surface of the tungsten lamp power supply body 1 through the magnetic strip 15.

[0021] The limiting structure includes a lower accommodating groove 7 arranged on the surface of the limiting seat 4, and an upper accommodating groove 8 arranged on the surface of the baffle 5. The upper accommodating groove 8 and the lower accommodating groove 7 form a chamber 9 for fixing the circuit.

[0022] See also Figure 3 Since the radii of the upper receiving groove 8 and the lower receiving groove 7 are different, assuming that the lower half of the wiring harness is located in the lower receiving groove 7, the upper half of the wiring harness cannot be completely located in the upper receiving groove 8, but will lift the baffle 5 for a distance through the upper receiving groove 8. At this time, the baffle 5 can drive the elastic component to move, and the wiring harness is clamped and fixed by the baffle 5.

[0023] The elastic component includes a sleeve 10, an elastic member and a groove 11. The groove 11 is arranged on the surface of the limit seat 4. The sleeve 10 is fixedly arranged at the bottom of the baffle 5. The sleeve 10 is vertically movably arranged in the groove 11. The elastic member is arranged between the baffle 5 and the groove 11 and accommodated inside the sleeve. The elastic member is arranged as a spring 12. The two ends of the spring 12 are respectively fixed to the surface of the baffle 5 and the surface of the groove 11. The sleeve is sleeved on the surface of the spring 12.

[0024] See also Figure 1 , 24. After the dust cover 6 is rotated, one side of the dust cover 6 can drive the magnetic strip 15 to contact the surface of the tungsten lamp power supply body 1, so that the magnetic strip 15 can adsorb and fix the dust cover 6 to the surface of the tungsten lamp power supply body 1 to fix the dust cover 6. Then open the dust cover 6, fix one end of the wire harness inside the power interface 2, and then pull the baffle 5 so that the baffle 5 drives the sleeve to move synchronously inside the groove 11. When the baffle 5 moves, it can stretch the spring 12 to deform and store energy. Then rotate the baffle 5 to expose the lower receiving groove 7. At this time, the other end of the wire harness can be Pass through the lower accommodating groove 7, then rotate the baffle 5 in the opposite direction and release the baffle 5. At this time, the baffle 5 can be reset under the elastic force of the spring 12, so that the baffle 5 covers the surface of the wiring harness through the upper accommodating groove 8. Since the radii of the upper accommodating groove 8 and the lower accommodating groove 7 are different, assuming that the lower half of the wiring harness is located in the lower accommodating groove 7, the upper half of the wiring harness cannot be completely located in the upper accommodating groove 8, but will be lifted up a distance by the upper accommodating groove 8. At this time, the baffle 5 can stretch the spring 12, and the elastic force of the spring 12 is transmitted to the baffle 5 to clamp and fix the wiring harness.

[0025] A cavity 13 is provided on the side of the limiting seat 4 , and the two cavities 13 are rotatably connected via a rotating shaft 14 .

After the adjustment is completed, the wire harness is fixed by the above method.
