Technical Field

[0001] The present invention relates to the technical field of power strips, and in particular to an assembly production process for power strips. Background Art

[0002] Existing power strips include conductive springs that are welded to wires. Some power strips are also equipped with USB and other mobile phone charging cable interfaces. However, there is no unified standard for welding the existing conductive springs to wires, so the safety is low. At the same time, the production efficiency of manually welding the wires is also low.

[0003] Therefore, based on the above-mentioned defects of the existing power strips, there is a need to improve the existing power strips. Summary of the Invention

[0004] The purpose of the present invention is to provide an assembly production process for a power strip in view of the deficiencies in the prior art, and the assembly production process solves the defects of the existing power strips, such as low safety.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions.

[0006] A production process for assembling a power strip comprises the following steps: first, processing a conductive spring sheet, bending one end of the spring sheet body to form a bent welding portion; second, assembling the conductive spring sheet onto the upper cover of the power strip and fixing it; and third, welding wires to the conductive spring sheet using a welding jig.

[0007] Furthermore, in the second step, the bent welding portions of the plurality of conductive springs are arranged side by side.

[0008] Furthermore, in the third step, the wire is first placed in the wire clamping channel of the butt welding jig, with the exposed part of the wire located on the positioning block of the butt welding jig. The wire is clamped and rotated so that the upper cover of the socket is vertical. The bent welding part of the conductive spring is placed on the positioning block, and welding is achieved by contacting the bent welding part of the conductive spring with the butt welding head downward.

[0009] The beneficial effects of the present invention are: during the production process, one end of the spring body of the conductive spring is bent to form a bent welding portion for welding wires, thereby achieving welding standardization; and the wires are welded to the conductive spring using a welding jig, thereby achieving high production efficiency.

[0033] See Figure 7 -- Figure 11 The conductive spring clip 018 of the present invention includes a spring clip body 1, which has a protruding block extending upward or downward, and the protruding block forms a plug interface 2 for inserting an external plug. The middle part of the spring clip body 1 is bent toward the left side of the spring clip body 1 to form a main body bending portion 4; one end of the spring clip body 1 is bent to form a bent welding portion 3, and the outer side surface of the bent welding portion 3 is used for welding the wire 017.

[0034] In the first step of the production process, the plug interface 2 is first punched and bent on the spring body 1 of the conductive spring 018, the main body bending portion 4 is punched or bent, and then one end of the spring body 1 is bent to form a bent welding portion 3.

[0035] Figure 7 、 Figure 8 In the conductive spring 018 shown in FIG, the spring body 1 is bent along the X-axis direction to form a bent welding portion 3 . Figure 9 、 Figure 10 、 Figure 11 The conductive spring piece 018 has a spring piece body 1 that is bent along the Y-axis direction to form a bent welding portion 3. Figure 10 In the figure, the middle portion of the spring body 1 of the conductive spring 018 is bent to form a main body bending portion 4.

Figure 10 The main body bending portion 4 of the spring sheet main body 1 is formed by bending, and the spring sheet main body 1 is in a vertical shape.

[0036] See Figure 1 -- Figure 6 The upper cover of the power strip of the present invention includes an upper cover body 100, and a side baffle 200 is formed on the upper cover body 100 along the length direction of the upper cover body 100. The conductive spring piece 018 is installed and fixed next to the side baffle 200. The conductive spring piece 018 is separated by the side baffle 200 to improve safety.

[0037] The circuit board 500 of the present invention is a low-voltage circuit board with a USB or Type-C interface. Therefore, the upper cover body 100 is formed with a raised front panel 300, which is connected to at least the front ends of the two side panels 200. The circuit board 500 is located in front of the front panel 300, and the conductive spring 018 and the circuit board 500 are located on either side of the front panel 300, thereby separating high-voltage and low-voltage areas and improving safety.

[0038] The upper cover body 100 of the present invention is protruded to form a positioning column, and a positioning seat 400 is fixed to the positioning column. The positioning seat 400 is locked on the positioning column. The positioning seat 400 includes a pressing portion 401, and the pressing portion 401 presses the conductive spring 018.

[0039] In the second step of the production process, the conductive spring clip 018 is embedded in the position next to the side baffle 200 of the upper cover of the power strip, and the positioning seat 400 is aligned with the positioning column on the upper cover body 100. It is fixed with screws so that the pressing part 401 of the positioning seat 400 presses the horizontal spring body 1. The bent welding parts 3 of multiple conductive spring clips 018 are arranged side by side to facilitate welding of wires 017 and achieve standardization.

[0040] The circuit board 500 of the present invention is electrically connected to a clip terminal block 501. The clip terminal block 501 includes a terminal and a clip. Figure 11 As shown, the terminal is used to electrically connect to the circuit board 500 and can be directly soldered to the circuit board 500 or connected to the circuit board 500 through conductive welding. The clip is directly connected to the conductive spring 018. The spring body 1 of the conductive spring 018 is vertical, and the clip is connected to the spring body 1 from top to bottom, which is very convenient for assembly.

[0041] In the second step of the production process, after assembling the conductive spring 018, an additional process can be added to assemble the circuit board 500 with the clip terminal block 501 pre-soldered onto the upper cover body 100 of the power strip, and then the clip terminal block 501 is clamped and fixed with the corresponding conductive spring 018. Figure 1 In the embodiment, the circuit board 500 is assembled in a horizontal shape, and the upper cover body 100 has an undercut to hold the circuit board 500 . Figure 3 In the embodiment, the upper cover body 100 has a mounting groove, the circuit board 500 is embedded in the mounting groove for positioning, and the mounting groove is located next to the front baffle 300. Figure 5 In the embodiment, the upper cover body 100 has a mounting groove, the circuit board 500 is embedded in the mounting groove for positioning, and the mounting groove is located next to the front baffle 300.

[0043] The fixture body 01 of the present invention has a fixed seat 02 above it, and an extension bar 03 extends from one side of the fixed seat 02. Three fixed blocks 04 are arranged at intervals on the extension bar 03 to form three wire clamping channels 05. The wire clamping channels are used to place the wires 017. The positioning block 011 is located next to the extension bar 03. A movable groove 013 is formed in the middle of the fixed seat 02, and a movable seat 06 is movably arranged in the movable groove 013. The side of the movable seat 06 has a movable bar 07. The extension bar 03 has a limiting groove 014 formed along the length direction. The limiting groove 014 passes through the fixed block 04. The movable bar 07 is movably located in the limiting groove 014. Three movable blocks 08 are arranged at intervals on the movable bar 07 to form three spacing grooves 09. The three movable blocks 08 are movably located in the three wire clamping channels 05 respectively. The movable seat 06 is driven by the cylinder 015 to move, so that the movable block 08 clamps the wire 017. As shown Figure 16 、 Figure 17 As shown, wire 017 is placed in wire clamping channel 05 and clamped by movable block 08. The exposed portion of wire 017 is located in positioning groove 012 of positioning block 011. Conductive spring 018 is welded to wire 017 via welding head 016 above jig body 01.
