[0001] This utility model relates to the field of wire bonding auxiliary tools, and in particular to a side terminal wire bonding auxiliary tool. Background Technology

[0002] In railway construction, indoor cables are often fixed to side terminals by welding. However, with existing construction methods, when welding wires to side terminals, it is difficult for the worker to hold the soldering iron in one hand and the solder wire in the other, making it difficult to stabilize the cable. This makes the cable prone to falling off and shaking, which affects the quality of the welding process. At the same time, after welding each cable, the next cable needs to be fixed, and the soldering iron needs to be placed in a safe position, which affects the construction efficiency.

[0003] Therefore, it is necessary to provide a new auxiliary tool for side terminal wire bonding to solve the above-mentioned technical problems. Utility Model Content

[0030] This utility model proposes an auxiliary tool for side terminal wire bonding, which aims to solve the problems of complex operation and low work efficiency in existing side terminal wire bonding operations.

[0031] like Figures 1 to 3 As shown, the side terminal welding auxiliary tool in this embodiment is used to assist in welding the cable to the conductive iron 1.1 of the side terminal 1. The conductive iron 1.1 is provided with a wire hole 1.1.1 and includes an outer frame bracket and a welding pad 3. The outer frame bracket includes two opposing frames 2, which enclose a welding space 2.4 for the side terminal 1, and the two frames 2 are detachably connected. The welding pad 3 is disposed between the two frames 2 and can abut against the lower surface of the conductive iron 1.1. The welding pad 3 is provided with wire grooves 3.1 spaced apart along the length direction. The wire grooves 3.1 are positioned opposite the wire hole 1.1.1 and are interference-fitted with the cable. The two frames 2 of the outer frame bracket are detachably connected to facilitate wire bonding operations on different side terminals 1. The detachable structure also prevents the cable from being trapped after welding, ensuring the quality of the cable welding. The welding space 2.4 formed by the two frames 2 matches the shape of the side terminal 1. By placing the wire bonding pad 3 between the two frames 2, it can fit tightly against the lower surface of the conductive iron 1.1 on the side terminal 1. The wire bonding pad 3 is provided with a wire groove 3.1 to guide and fix the cable, so that the copper core of the cable can be quickly inserted into the wire hole 1.1.1 of the conductive iron 1.1 and the cable can be firmly fixed during the welding process, improving welding stability and quality, simplifying the operation process, and improving work efficiency.

[0032] The frame 2 has multiple grooves 2.1 spaced vertically on the side facing the welding space 2.4; the wire bonding pad 3 is positioned at both ends of the wire bonding pad 3 within two grooves 2.1 at the same height. The wire bonding pad 3 is inserted into the grooves 2.1 at different heights on the two frames 2 to accommodate welding operations of conductive irons 1.1 at different heights.

[0033] Specifically, the wire bonding pad 3 is provided with a horizontal surface 3.2 and a vertical surface 3.3 that are vertically connected. The horizontal surface 3.2 abuts against the lower surface of the conductive iron 1.1, and the vertical surface 3.3 is located on the side of the wire bonding pad 3 that is opposite to the side terminal 1. The wire groove 3.1 is provided at the connection between the horizontal surface 3.2 and the vertical surface 3.3, and the wire groove 3.1 is formed by a concave arc wall 3.4 and two side walls 3.5. The two side walls 3.5 are vertically arranged and connected by the concave arc wall 3.4. The wire bonding pad is a cuboid, with its two ends inserted into two grooves 2.1 of the same height on the two frames 2, so that the horizontal surface 3.2 abuts against the lower surface of the conductive iron 1.1. The wire groove 3.1 is set at the connection between the horizontal surface 3.2 and the vertical surface 3.3 on the wire bonding pad 3, so that the cable can be introduced into the wire groove 3.1 from the direction of the vertical surface 3.3. When the cable is inserted, it can enter the wire hole 1.1.1 of the conductive iron 1.1 along the concave arc surface arm of the wire groove 3.1. The cable sheath is fixed in the arc-shaped wire groove 3.1. There is no need to hold the cable by hand during welding, which simplifies the operation and improves the welding efficiency.

[0034] Furthermore, the side terminal 1 is provided with multiple conductive irons 1.1, which are arranged in a rectangular pattern. The number of wire grooves 3.1 is the same as the number of columns of conductive irons 1.1, and the wire grooves 3.1 correspond one-to-one with the wire holes 1.1.1 on the conductive irons 1.1. The number of grooves 2.1 on the frame 2 is the same as the number of rows of conductive irons 1.1. The wire bonding pad 3 is provided with the same number of wire grooves 3.1 as the number of columns of conductive irons 1.1 on the side terminal 1, so as to fix the same row of conductive irons 1.1 at the same time, so as to facilitate welding by the operator and thus improve the welding quality and efficiency. For different rows of conductive irons 1.1, the operator can place the wire bonding pad 3 in the two grooves 2.1 at the corresponding height of the row of conductive irons 1.1 to realize the wire bonding operation of different rows of conductive irons 1.1.

[0035] Furthermore, the frame 2 is provided with a vertically arranged first side surface 2.2 and a second side surface 2.3. The first side surface 2.2 is positioned directly opposite the welding space 2.4, and the first side surfaces 2.2 of the two frames 2 respectively abut against the two sides of the side terminal 1; the second side surface 2.3 is perpendicularly connected to the first side surface 2.2, and the second side surface 2.3 is located on the side of the frame 2 opposite to the side terminal 1; a groove 2.1 is provided at the connection between the first side surface 2.2 and the second side surface 2.3. The side terminal 1 is clamped between the first side surfaces 2.2 of the two frames 2, and the groove 2.1 is provided at the connection between the first side surface 2.2 and the second side surface 2.3 to facilitate the removal and placement of the soldering pad 3 after the two frames 2 are installed.

[0036] See also Figure 4 The outer frame support also includes a first fastening structure 4 and a second fastening structure 5 respectively disposed on the two frames 2. The first fastening structure 4 includes two first elastic arms 4.1 spaced apart along the extension direction of the first side 2.2. The two first elastic arms 4.1 are disposed opposite to each other. The end of the first elastic arm 4.1 away from the frame 2 forms a protrusion 4.1.1 extending toward the other first elastic arm 4.1. The second fastening structure 5 includes two second elastic arms 5.1 spaced apart along the extension direction of the first side 2.2. 1. The second elastic arm 5.1 is arranged opposite to the frame 2. The end of the second elastic arm 5.1 away from the frame 2 forms a fastening part 5.1.1. The end of the fastening part 5.1.1 near the frame 2 forms a stepped surface A1 corresponding to the protrusion 4.1.1. The end of the fastening part 5.1.1 away from the frame 2 forms a guide surface A2 that is gradually narrowed towards the first elastic arm 4.1. The two second elastic arms 5.1 can extend between the two first elastic arms 4.1.1 and are abutted and limited by the stepped surface A1 and the corresponding protrusion 4.1.1 so that the second fastening structure 5 and the first fastening structure 4 are fastened together. Applying pressure to the two second elastic arms 5.1 to bring them closer together allows the engaging portions 5.1.1 of the two second elastic arms 5.1 to extend between the two first elastic arms 4.1. Releasing the pressure causes the two second elastic arms 5.1 to spring back, allowing the stepped surface A1 of the engaging portion 5.1.1 to abut against the corresponding protrusion 4.1.1, thus completing the engagement of the first engaging structure 4 and the second engaging structure 5. The gradually tapering guide surface A2 serves as a guide during the engagement process. The two frames 2 are engaged via the first engaging structure 4 and the second engaging structure 5, facilitating quick disassembly and installation of the two frames 2 and improving work efficiency.

[0037] In this embodiment, a connecting portion 2.5 is formed at the bottom of the frame 2, the connecting portions 2.5 of the two frames 2 abut against each other, and the connecting portion 2.5 forms a slot 2.5.1 with a top opening; see also Figure 5The side terminal soldering auxiliary tool also includes a drip-proof tray 6 and a plug structure 7. The drip-proof tray 6 forms a reservoir 6.1 for holding dripping solder. The plug structure 7 is disposed on the drip-proof tray 6, and a gap is formed between the plug structure 7 and the drip-proof tray 6 for the edge of the slot 2.5.1 to be set. The plug structure 7 can be inserted into the slots 2.5.1 of the two frames 2 to connect the drip-proof tray 6 to the two frames 2. By disassembling the plug structure 7 into the slots 2.5.1 of the two frames 2, a detachable connection between the drip-proof tray 6 and the two frames 2 can be achieved, and the lower part of the two frames 2 can be fixed and limited, ensuring the stability of the overall structure. In addition, the drip-proof tray 6 can prevent solder from splashing. In this embodiment, the solder is molten solder, which not only ensures that the construction personnel are not burned by the dripping molten solder, but also saves the time of cleaning up the dripping molten solder in traditional construction.

[0038] The anti-drip tray 6 has a downwardly recessed guide arc surface 6.2 formed on the side wall 3.5 near the frame 2. When the molten solder drips onto the guide arc surface 6.2, it can slide along the guide arc surface 6.2 into the container 6.1 to reduce solder splashing and ensure the safety of the operators.

[0039] In addition, the side terminal soldering auxiliary tool also includes a soldering iron stand 8, which is detachably mounted on the drip-proof tray 6 and is used to support the soldering iron. Installing the soldering iron stand 8 on the drip-proof tray 6 provides a stable and convenient placement for the soldering iron, eliminating the need for workers to repeatedly bend over to pick up the soldering iron placed on the ground, thus significantly improving work efficiency.
