[0040] The pressure welding clamp of the first aspect of the present utility model is described below with reference to the accompanying drawings of the specification. It should be noted that, in order to facilitate understanding and description, in the embodiments of the present utility model, the front-to-back direction is shown as the first direction, the left-to-right direction is shown as the second direction, and the up-to-down direction is shown as the third direction in the accompanying drawings of the specification, and the first direction, the second direction and the third direction are perpendicular to each other.

[0041] The pressure welding clamp provided by the embodiments of the present utility model can effectively limit the wire and the core, can reduce the mutual interference of the cores during welding, and improves the welding efficiency of the cores.

[0042] Referring to FIGS. 1 and 2, Figure 1 and Figure 2 The pressure welding clamp 10 includes a base 100 and a cover plate 200.

[0043] The base 100 includes a mounting portion 110, and the surface of the mounting portion 110 is provided with a wire groove 114 and a plurality of clamping grooves 112. The wire groove 114 is suitable for placing the wire, and the clamping grooves 112 are suitable for placing the cores. The wire groove 114 is communicated with each clamping groove 112 along the first direction, so that the wire placed in the wire groove 114 can have the cores placed in the clamping grooves 112. Meanwhile, the plurality of clamping grooves 112 are arranged at intervals along the second direction, and the first direction is perpendicular to the second direction. In this embodiment, the wire groove 114 and the clamping groove 112 have groove walls along the second direction, and when the wire is contained in the wire groove 114 and the cores are contained in the clamping grooves 112, the groove walls limit the wire and the cores to move along the second direction (left-to-right direction) to limit the wire and the cores to move in and out of the wire groove 114 and the clamping grooves 112 along the first direction (front-to-back direction) or the third direction (up-to-down direction).

[0044] Further, the plurality of card slots 112 are open to the edge of the mounting portion 110 in the first direction from the end of the wire slot 114, such that when the cores are placed in the card slots 112, a portion of each core in each card slot 112 is placed outside the card slot 112, and the core placed outside the card slot 112 is the core to be welded to the main board 211. The cover plate 200 is connected to the base 100, and the cover plate 200 is movable relative to the base 100, such that the cover plate 200 itself can be switched between the first position and the second position.

[0045] Referring to Figure 5 As shown in FIG. 1, when the cover plate 200 is in the first position, the cover plate 200 avoids the mounting portion 110 to open the wire slot 114 and the card slot 112, such that the wire can enter and exit the wire slot 114, and the core can enter and exit the card slot 112.

[0046] Referring to Figure 6 As shown in FIG. 2, when the cover plate 200 is in the second position, the cover plate 200 covers the mounting portion 110 to close the wire slot 114 and the card slot 112, such that the wire and the core are restricted from entering and exiting the wire slot 114 and the card slot 112 in the third direction. At the same time, the cover plate 200 is pressed against the wire and the core to fix the wire and the core in the current position, thereby restricting the movement of the wire and the core in the first direction. Thus, by cooperating the card slot 112 and the wire slot 114 with the cover plate 200, the movement of the wire and the core relative to the mounting portion 110 can be restricted.

[0047] Specifically, the wire contains a plurality of cores, and when it is necessary to fix the wire and the core, the cover plate 200 can be placed in the first position, the wire is contained in the wire slot 114, and the cores are respectively contained in the card slots 112 one by one, and then the cores are fixed. Since the plurality of card slots 112 are arranged separately in the second direction, the cores can be respectively contained in the independent card slots 112, thereby avoiding the situation that the cores interfere with each other during fixing. After the cores are fixed, the cover plate 200 is switched from the first position to the second position, and the cover plate 200 is pressed against the mounting portion 110 to hinder the movement of the wire and the core. Then, the wire and the core fixed in the press-welding clamp 10 can be welded.

[0048] The welding fixture 10 of the embodiment of the utility model fixes the wire through the wire slot 114, fixes the core through the clamping slot 112, and closes the import and export of the wire slot 114 and the clamping slot 112 through the cover plate 200, limits the movement of the wire and the core relative to the mounting portion 110, so that the core does not deviate during welding, thereby improving the welding quality and efficiency of the core. At the same time, by arranging multiple clamping slots 112 and arranging the multiple clamping slots 112 in the mounting portion 110, the core to be welded can be accommodated in the independent clamping slot 112, thereby avoiding mutual interference during core welding, so as to further improve the welding efficiency and yield.

[0049] In some embodiments, referring to Figure 2 、 Figure 4 and Figure 6 , the base 100 further includes an extension portion 120, the extension portion 120 is connected to the mounting portion 110 in the first direction, and the extension portion 120 is arranged on the side of the clamping slot 112 away from the wire slot 114 in the first direction. Since the core is placed in the clamping slot 112, a part of the core will be arranged outside the clamping slot 112, and this part of the core will be arranged in the extension portion 120, but a small part of the core will be arranged outside the extension portion 120 to facilitate subsequent processing of the core. The extension portion 120 provides support for the core placed outside the clamping slot 112, preventing the core from sagging and affecting subsequent processing of the core. The cover plate 200 includes a plate body 210 and a pressing portion 220 connected thereto, the pressing portion 220 is a component extending in the third direction, used to press the core to limit the movement of the core. When the cover plate 200 is in the second position, the plate body 210 is arranged on the mounting portion 110 to close the wire slot 114 and the clamping slot 112 in the third direction, limiting the movement of the wire and the core in the third direction. The pressing portion 220 is connected to the extension portion 120, and the pressing portion 220 is used to press the core on the extension portion 120 to limit the movement of the core.

[0050] Further, in some embodiments, referring to Figures 7 to 10As shown, the pressing portion 220 is provided with a plurality of fixing holes 221 on the side away from the plate body 210, the plurality of fixing holes 221 are arranged at intervals along the second direction, and the plurality of fixing holes 221 are communicated with the pressing portion 220 along the third direction. When the cover plate 200 is in the second position, the pressing portion 220 will be pressed on the extension portion 120, at this time, the plurality of fixing holes 221 will cooperate with the surface of the extension portion 120 to form a plurality of accommodation cavities for accommodating the core portion. When the core portion is fixed in the card slot 112 and part of the core portion is arranged outside the card slot 112, the core portion arranged outside the card slot 112 will be arranged in the accommodation cavity. In this embodiment, the fixing hole 221 corresponds to the card slot 112 one by one, that is, the centers of the plurality of fixing holes 221 are respectively aligned with the positions of the respective card slots 112 along the first direction, the interval distance of the fixing holes 221 along the second direction is also the same as the interval distance of the plurality of card slots 112, and the number of the fixing holes 221 is the same as the number of the card slots 112. Therefore, when the core portion passes through the card slot 112 and is arranged outside the card slot 112, the core portion can also be accommodated in the independent accommodation cavity. The accommodation cavity can limit the movement of the core portion arranged outside the card slot 112, and at the same time, the accommodation cavity can avoid the pressing portion 220 directly pressing on the core portion, causing damage or even breakage of the core portion.

[0051] In some embodiments, referring to Figures 2 to 5 As shown, the mounting portion 110 further includes a main body 111 and a fixing member 113, the main body 111 is detachably connected to the fixing member 113, the plurality of card slots 112 are arranged on the main body 111, and the wire slot 114 is arranged on the fixing member 113. The material flexibility of the fixing member 113 is greater than that of the main body 111. Specifically, because the wire has a protective layer wrapped outside, and the material of the core portion is a metal material, the strength of the protective layer is less than that of the metal material. Moreover, the main body 111 needs to be clamped during subsequent processing, so the material of the main body 111 is also commonly a metal material, such as metal iron or metal steel. Therefore, making the material flexibility of the fixing member 113 greater than that of the main body 111 can protect the protective layer of the wire during fixing of the wire, avoiding damage and breakage of the protective layer of the wire, which may cause electric shock and injury to personnel. At the same time, making the main body 111 and the fixing member 113 detachably connected can replace the fixing member 113 to protect the external material of the wire when welding wires of different sizes or wires of different materials, avoiding loss of the wire, and improving the universality of the press welding clamp 10, which can be suitable for various welding wires.

[0052] In some embodiments, the welding fixture 10 further includes a plurality of indicators 300 , which are connected to the main body 111 and arranged between the wire groove 114 and the card slot 112 in the first direction. The plurality of indicators 300 serve as indicators when securing the core. Because the wire contains multiple cores, each core conducts different currents and voltages. Therefore, when securing the cores, the cores need to be arranged in a certain order to avoid welding errors that could cause short circuits on the circuit board. By providing multiple indicators 300 , a reference position is provided when securing the cores, reducing the possibility of incorrect core welding positions. Furthermore, the plurality of indicators 300 are spaced apart along the second direction, and the indicators 300 correspond one-to-one with the card slots 112, i.e., the number and position of each indicator 300 correspond one-to-one with the card slots 112.

[0053] Specifically, in one of the examples, see Figure 3 and Figure 5 As shown, the main body 111 is provided with a plurality of grooves, and the number of the grooves is consistent with the number of the indicator members 300. The position of each groove corresponds one-to-one with the card slot 112, and each groove accommodates an indicator member 300. Thus, each indicator member 300 corresponds one-to-one with the card slot 112. In this embodiment, the plurality of indicator members 300 have different colors, and the color indication is used to assist in the fixation of the core, effectively ensuring the accuracy of the welding position. For example, the plurality of cores include cores in colors such as red, white, and green, and the plurality of indicator members 300 also include indicator members 300 in colors such as red, white, and green. By matching the colors of the indicator members 300 and the core, the accuracy of the fixation of the core and the welding position is improved.

[0054] In another example, the indicator 300 may also indicate directly through text, with colored text engraved in the corresponding groove to ensure the accuracy of the fixing and welding position of the core, or through symbols and numbers.

[0055] In some embodiments, see Figures 2 to 6 As shown, the cover 200 includes a main plate 211 and a sub-plate 212 connected to each other. The main plate 211 and the sub-plate 212 are movably connected to the mounting portion 110 so that the cover 200 can be switched between the first position and the second position. At the same time, the sub-plate 212 can move independently relative to the main plate 211. Specifically, in this embodiment, see Figures 2 to 6As shown, the main plate 211 and the auxiliary plate 212 are part of the plate body 210, and the crimping clamp 10 further comprises a rotating shaft 400 connected to the mounting portion 110, and the main plate 211 and the auxiliary plate 212 are rotatably connected to the mounting portion 110 through the rotating shaft 400. After the wire is accommodated in the wire slot 114, the auxiliary plate 212 can rotate relative to the main plate 211 around the rotating shaft 400, so as to pre-press the wire, to ensure that the wire does not move the core portion relative to the mounting portion 110 when the core portion is fixed in the clamping slot 112.

[0056] In another embodiment, the crimping clamp 10 comprises a guide rail. The guide rail has a first end and a second end in the third direction, the first end of the guide rail is connected to the mounting portion 110, and the second end is connected to the main plate 211 and the auxiliary plate 212, and the main plate 211 and the auxiliary plate 212 are slidably connected to the guide rail. In the first position, the main plate 211 and the auxiliary plate 212 are spaced apart on the mounting portion 110 to open the wire slot 114 and the clamping slot 112. In the second position, the main plate 211 and the auxiliary plate 212 slide towards the mounting portion 110 in the third direction, so that the main plate 211 and the auxiliary plate 212 are arranged on the mounting portion 110. After the wire is accommodated in the wire slot 114, the auxiliary plate 212 can slide relative to the main plate 211 along the guide rail, so as to pre-press the wire.

[0057] Further, the base 100 is also provided with an opening 115, which is arranged on the side of the wire slot 114 away from the clamping slot 112 in the first direction, and the opening 115 communicates with the wire slot 114. The opening 115 is suitable for the wire to enter and exit the wire slot 114 in the first direction. When the cover plate 200 is in the second position, at least a part of the auxiliary plate 212 corresponds to the opening 115 in the third direction. That is, when the auxiliary plate 212 is arranged on the wire slot 114, a part of the auxiliary plate 212 is pressed on the wire slot 114, and the other part is arranged in the opening 115. The auxiliary plate 212 arranged in the opening 115 is in a suspended state, and when it is necessary to rotate the auxiliary plate 212 or slide the auxiliary plate 212 to separate the auxiliary plate 212 from the mounting portion 110, the activity of the auxiliary plate 212 can be realized by grasping the part of the auxiliary plate 212 arranged in the opening 115, thereby improving the convenience of the activity of the auxiliary plate 212.

[0058] In some embodiments, referring to Figure 4 and Figure 5 As shown, the base 100 further comprises a partition plate 116 connected to the mounting portion 110 and arranged in the wire slot 114. The partition plate 116 divides the wire slot 114 to form a first mounting slot 1141 and a second mounting slot 1142, and the first mounting slot 1141 and the second mounting slot 1142 are arranged in the second direction. The sizes of the first mounting slot 1141 and the second mounting slot 1142 in the second direction are different, so that the first mounting slot 1141 and the second mounting slot 1142 can be used to mount wires of different sizes.

[0059] In some embodiments, referring to Figures 2 to 5 As shown, the pressure welding clamp 10 further comprises a magnetic attraction member, the mounting portion 110 is provided with a through hole 117 in the third direction, and the magnetic attraction member is accommodated in the through hole 117. In the second position, the magnetic attraction member is connected to the cover plate 200 so that the cover plate 200 is fixedly connected to the mounting portion 110. In other embodiments, the connection between the mounting portion 110 and the cover plate 200 can also be threaded connection, or can be a latch connection, or a buckle connection, etc.

[0060] The pressure welding device of the second aspect of the utility model is described below. The pressure welding device comprises a machining device and the pressure welding clamp 10 described in any of the above embodiments. The machining device comprises a machining seat for fixedly connecting the pressure welding clamp 10. The mounting portion 110 is connected to the machining seat. The machining device is used for cutting and welding the core portions placed outside the clamping grooves 112.

[0061] Specifically, after the wire is fixed to the wire groove 114 and the core portion is fixed to the clamping groove 112, a part of the core portion of each clamping groove 112 is placed outside the clamping groove 112, and this part of the core portion is the core portion that needs to be further processed, i.e. cutting and welding. After the pressure welding clamp 10 is fixed to the machining seat, the cutting tool is used to cut the core portion placed outside the clamping groove 112 in the third direction, so that the length of the core portion to be welded can be kept consistent in the subsequent welding process, thereby improving the welding quality of the core portion. In this embodiment, only a part of the core portion placed outside the clamping groove 112 is cut during the cutting process, and the entire core portion placed outside the clamping groove 112 does not need to be cut, so that a part of the core portion is still retained outside each clamping groove 112. Thus, during the welding process, the core portion outside the clamping groove 112 can be directly welded without the need to re-adjust the wire and the core portion. During the welding process, the cut core portion is placed on the main plate 211, and the machining device is used to weld the core portion outside the clamping groove 112, so that the size of the soldering tin point during the welding of the core portion can be kept consistent, thereby further improving the welding quality.

[0062] The pressure welding device of the utility model embodiment can cut the core portion placed outside the clamping groove 112 after the wire and the core portion are fixed to the mounting portion 110, so that the welding length of the core portion can be kept consistent, thereby avoiding the situation that the welding length of the core portion is inconsistent, resulting in inconsistent resistance of each core portion during power conduction, affecting the stability of the conduction voltage and current after welding, and reducing the welding quality. At the same time, the machining device can be used to uniformly weld the core portion, so that the soldering tin point of the core portion can be kept consistent, thereby avoiding the situation that the soldering tin point is too small due to manual welding, resulting in poor welding quality, or the soldering tin point is too large, resulting in burning of the element and increasing the short circuit risk of the element.

[0063] The utility model embodiment has been explained in detail above in combination with the drawings, but the utility model is not limited to the above-mentioned embodiment, still can make various changes in the knowledge range possessed by the ordinary skilled in the art without departing from the utility model's tenet. Besides, the embodiment and the feature in the embodiment of the utility model can be combined mutually in the case of not conflicting.
