Description

Technical Field

[0001] This utility model relates to the field of busbar manufacturing technology, and in particular to a side plate and resin busbar joint casting mold. Background Technology

[0002] Busbar connectors are generally made of copper busbars, with connectors at both ends and an insulating material, such as a resin sleeve, covering the middle section. (See reference...) Figure 6 Busbar joints are key components connecting busbar sections in power systems. The common method for insulation treatment of the intermediate section of a busbar joint is to cast iron into the copper busbar. After casting, the busbar joint can be used in various harsh and high-cleanliness environments, and it is a processing method with high sealing performance among busbar joints.

[0003] The casting process of busbar connectors requires the use of resin busbar connector casting molds. Existing casting molds are mostly composed of sheet metal parts. The casting cavity of the casting mold is formed by side plates and bottom plates. However, the ports that accommodate the copper busbars are located at both ends of the casting cavity and are difficult to form. Therefore, in the existing technology, multiple sheet metal parts need to be assembled and connected. The sheet metal parts are fixed together with bolts, which makes the existing casting molds cumbersome to assemble and disassemble and has low efficiency. Utility Model Content

[0030] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0031] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0032] Reference Figure 1 The first embodiment of this utility model provides a side plate. The side plate 100 is an important component in forming the resin busbar connector casting mold. Specifically, it includes a main board segment 101, which is adapted to the resin sleeve m1 of the busbar connector m.

[0033] Connecting sections 102 extend from both ends of the main board segment 101 to one side, forming an obtuse angle between the connecting sections 102 and the main board segment 101. After the busbar connector m is cast, the main body of the resin sleeve m1 is formed by the casting cavity S enclosed by the main board segment 101 and the base plate 200; the resin covering the edge of the copper busbar m2 is formed by the casting cavity S enclosed by the connecting section 102 and the base plate 200, making the edge of the copper busbar m2 beveled, which is beneficial for further processing of the busbar connector m and saves resin raw materials.

[0034] The connecting sections 102 at both ends extend away from the main board section 101 and are provided with mounting sections 103. The mounting sections 103 are parallel to the main board section 101, that is, they are adapted to the copper busbar m2. After the copper busbar m2 is placed in the casting mold, the two sides of the copper busbar m2 are clamped between the mounting sections 103.

[0035] As can be seen from the above, the connecting segment 102 is transitionally connected between the motherboard segment 101 and the mounting segment 103.

[0036] Furthermore, a motherboard side edge 101a is provided extending to one side of the top surface of the motherboard segment 101, which helps to increase the bending resistance of the motherboard segment 101.

[0037] Reference Figure 1 The second embodiment of this utility model differs from the previous embodiment in that the upper part of the mounting section 103 is provided with a mounting hole 106, and a fixing hole 109 is provided on the upper side of the mounting hole 106. The inner diameter of the mounting hole 106 is larger than the inner diameter of the fixing hole 109. The mounting hole 106 and the fixing hole 109 are connected, and the maximum size of the connection is smaller than the inner diameter of the fixing hole 109.

[0038] The mounting sections 103 at both ends extend vertically to the other side of the main board section 101 and are provided with mating sections 104. The mating sections 104 have notches 105 at the upper and lower ends respectively. The top of the upper notch 105 is connected to the top surface of the mating section 104, and the bottom of the notches 105 at the upper and lower ends respectively has a slope 105a.

[0039] The bottom surfaces of the mounting section 103 and the mating section 104 are respectively provided with a first plug-in plate 107 extending downwards. The lower part of the first plug-in plate 107 is tapered, and the upper part is provided with a slot 107a.

[0040] A plurality of second plug-in plates 108 are equally spaced on the bottom surface of the main board segment 101. Each second plug-in plate 108 includes a vertical segment 108a extending downward along the bottom surface of the main board segment 101, and a horizontal segment 108b extending to one side along the vertical segment 108a, so that the second plug-in plate 108 forms a hook shape.

[0041] It should be noted that the main board segment 101, main board side edge 101a, connecting segment 102, mounting segment 103, mating segment 104, first plug-in plate 107, second plug-in plate 108, notch 105, mounting hole 106, and fixing hole 109 are all formed by cutting, punching, and bending a single metal plate, so that the side plate 100 is integrally formed. This avoids the time and effort required for assembly and also avoids the risk of material overflow between components.

[0042] Reference Figure 2 and Figure 3 The third embodiment of this utility model provides a resin busbar connector casting mold. Existing resin busbar connectors are generally cast using a casting mold. The copper busbar is placed inside the casting mold, with the end of the copper busbar extending out of the casting mold. Then, molten resin is poured into the mold from the top of the casting mold to form the busbar connector m.

[0043] The resin busbar connector casting mold includes: a base plate 200, and the base plate 200 connecting to and supporting the mold as a whole.

[0044] The base plate 200 is detachably connected to the two sides of the side plate 100. The two sets of side plates 100 are installed on the base plate 200 at intervals and are symmetrical to each other. The two sets of side plates 100 and the base plate 200 surround each other on three sides to form the casting cavity S of the casting mold. The top of the two sets of side plates 100 forms a casting port S1, that is, the casting port S1 is connected to the casting cavity S in the vertical direction.

[0045] In addition, a fixing component 300 is disposed at both ends of the two sets of side plates 100. The fixing component 300 includes a clamping plate 301 that restricts the relative position of the two sets of side plates 100. The clamping plate 301 not only prevents the side plate 100 from moving away from its installation angle and prevents the side plate 100 from tilting, keeping the side plate 100 and the base plate 200 in a cuboid state, but also surrounds the two ends of the side plate 100 in the horizontal direction to form a port S2 for inserting and fixing the copper busbar m2. At the same time, the port S2 cooperates with the copper busbar m2 to prevent molten resin from overflowing.

[0046] When the clamping plate 301 is assembled with the mating section 104, since the top of the notch 105 at the upper end is connected to the top surface of the mating section 104, the two limiting grooves 302 opened on the upper clamping plate 301 can be directly fitted onto the notch 105 from top to bottom, and then moved to the mating section 104 through the inclined surface 105a at the bottom of the notch 105, so that the clamping plate 301 is engaged with the upper part of the mating section 104.

[0047] The two limiting grooves 302 on the lower plate 301 are respectively aligned with the lower notch 105. The plate 301 is inserted into the notch 105 and then moved to the mating section 104 through the inclined surface 105a at the bottom of the notch 105, so that the plate 301 is engaged with the lower part of the mating section 104. The notch 105 improves the convenience of assembling the plate 301 and the mating section 104.

[0048] Two clamping plates 301 are set at each end. The two clamping plates 301 are connected to the upper and lower sides of the mating section 104 respectively. The mounting sections 103 on both sides and the two clamping plates 301 installed at their corresponding ends form a port S2. The port S2 has the same cross-sectional dimensions as the copper busbar m2. After the copper busbar m2 is placed in the casting mold, both ends of the copper busbar m2 extend along the port S2. The port S2 is set to prevent overflow due to the gap between it and the copper busbar m2.

[0049] Furthermore, the base plate 200 is provided with a number of insertion holes 201, the positions of which match the shape of the bottom surface of the side plate 100.

[0050] Furthermore, the tapered shape at the lower part of the first plug-in plate 107 on the bottom surface of the mounting section 103 and the mating section 104 facilitates the insertion of the first plug-in plate 107 into the plug-in hole 201.

[0051] The second plug-in plate 108, which is equally spaced on the bottom surface of the main board segment 101, is adapted to be hooked into the plug-in hole 201 opened on the base plate 200.

[0052] Specifically, when assembling the side plate 100 and the base plate 200, the side plate 100 is first parallel to the base plate 200. After the second plug-in plate 108 is inserted into the plug-in hole 201, the side plate 100 is rotated 90 degrees so that the second plug-in plate 108 hooks onto the bottom surface of the base plate 200.

[0053] It should be noted that when the side plate 100 rotates 90 degrees, since the lower part of the first plug-in plate 107 is set as a cone, the first plug-in plate 107 is inserted into the corresponding plug-in hole 201 during the rotation of the side plate 100. After the second plug-in plate 108 hooks onto the bottom surface of the base plate 200, the slot 107a opened on the upper part of the first plug-in plate 107 is engaged with the base plate 200.

[0054] It should be noted that the shape of the first plug-in plate 107 and the second plug-in plate 108 is designed to facilitate the simultaneous insertion of the first plug-in plate 107 and the second plug-in plate 108 into the plug-in hole 201.

[0055] Furthermore, refer to Figure 4 The bottom plate 200 has upward-extending retaining edges 202 at both ends, and the retaining edges 202 are used to install the clamping plate 301; the bottom plate 200 has downward-extending bottom plate side edges 203 on both sides, which can prevent the bottom plate 200 from deforming in its length direction.

[0056] Preferably, the base plate 200, the retaining edge 202, the side edge of the base plate 203, and the insertion hole 201 are formed by cutting, bending, and punching a metal plate, so that the base plate 200 is integrally formed, avoiding the time-consuming and laborious assembly.

[0057] When the base plate 200 and the side plate 100 are fixedly assembled, the second plug-in plate 108 is inserted through the plug-in hole 201 of the base plate 200 and hooks onto the bottom surface of the base plate 200, thus completing the fixed connection between the main plate segments 101 on both sides and the base plate 200; the first plug-in plate 107 of the side plates 100 on both sides is inserted vertically through the plug-in hole 201 of the base plate 200 to initially position the relative positions of the mounting segment 103 and the mating segment 104 with the base plate 200; after the fixed connection, a casting cavity S is formed between the main plate segment 101 and the base plate 200, and the top of the main plate segments 101 on both sides serves as the casting port S1.

[0058] Reference Figure 3 and Figure 5 In the fourth embodiment of this utility model, unlike the previous embodiment, the fixing component 300 further includes a mounting component 303. The mounting component 303 includes a pin 303b, and connecting rods 303c are fixedly connected to both ends of the pin 303b. The outer diameter of the connecting rods 303c is smaller than the outer diameter of the pin 303b. The outer diameter of the pin 303b is consistent with the fixing hole 109, so that after the pin 303b enters the fixing hole 109 through the mounting hole 106, it can be fixed in the fixing hole 109.

[0059] The other end of the connecting rod 303c is fixedly connected to a stop 303d. The stop 303d is shaped like a frustum of a cone. The small diameter end of the stop 303d is fixedly connected to the connecting rod 303c. The maximum outer diameter of the stop 303d is smaller than the mounting hole 106 so that the stop 303d can pass through the mounting hole 106.

[0060] Furthermore, the mounting assembly 303 also includes a bolt 303a, which is screwed through a threaded through hole 303e in the middle of the pin 303b; the upper clamping plate 301 has a threaded hole in the middle, and the lower part of the bolt 303a is screwed to the clamping plate 301, so that the upper clamping plate 301 is fixedly connected to the mounting assembly 303 by the bolt 303a.

[0061] When installing the 301 card:

[0062] First, screw the bolt 303a onto the pin 303b. The stop pieces 303d at both ends pass through the mounting holes 106 respectively. Pull the pin 303b upward so that the fixing holes 109 on both sides move closer to the connecting rod 303c along the cone shape of the stop piece 303d. Gradually, the connecting rod 303c is engaged and inserted into the fixing hole 109, thus fixing the position of the mounting assembly 303.

[0063] Next, install the card plate 301 located on the upper side onto the main board segment 101, and move it along the main board segment 101 to the appropriate position. Tighten the bolt 303a to fix the position of the card plate 301.

[0064] It should be noted that the positioning position of the upper clamping plate 301 can be adjusted by adjusting the relative position of the bolt 303a and the pin 303b. That is, when the bolt 303a is turned downward, the positioning position of the clamping plate 301 will shift downward; when the bolt 303a is turned upward, the positioning position of the clamping plate 301 will shift upward.

[0065] The lower plate 301 first engages with the mating section 104, then slides downwards and is accommodated within the retaining edge 202 formed by the upward extension of both ends of the base plate 200, thus fixing the position of the lower plate 301.

[0066] Reference Figure 3 The fifth embodiment of this utility model differs from the previous embodiment in that the resin busbar joint casting mold also includes a release mold 400, the two sides of which are adapted to fit against the side plate 100.

[0067] After the base plate 200, side plate 100 and fixing component 300 are assembled, the demolding template 400 is placed on the top surface of the base plate 200. The demolding template 400 can cover the insertion hole 201 to prevent material overflow. After casting, the side plate 100 is removed, and the demolding template 400 is lifted to separate the cast busbar connector m from the base plate 200.

[0068] This invention reduces the number of mold parts and improves the assembly efficiency of the mold by using an integrally formed side plate 100 and an integrally formed base plate 200. It also avoids overflow of molten resin. The cooperation between the clamping plate 301 and the mounting section 103 forms the port S2 for inserting the copper busbar m2, which simplifies the structure of the port S2. The position of the clamping plate 301 can be adjusted according to the width of the copper busbar m2 by cooperating with the mounting component 303. This allows the mold to be suitable for casting more types of copper busbar m2.

[0069] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
