Technical Field

[0001] The utility model relates to the field of motor controllers, and specifically to a controller housing integrated with wiring terminals. Background Art

[0002] The environmental and energy crises have currently become global issues. Electric vehicles, with their advantages of zero pollution and wide energy sources, have become the future development trend. As one of the core components of electric vehicles, it is particularly important to design a controller with reliable quality and excellent performance.

[0003] Currently, there are two main assembly structures for motor controllers: 1. The wiring terminals are separated from the circuit board, fixed to the base using screws, and then the housing is assembled using screws; 2. The wiring terminals are welded to the circuit board, and then the circuit board and the housing are fixed using screws. That is to say, the housing and the wiring terminals are separated in both of these two methods, with more assembly processes and material categories, and higher labor and material management costs.

[0004] Therefore, a controller housing integrated with wiring terminals is provided to solve the problems raised in the above background art. Summary of the Utility Model

The wiring terminal group includes a wiring terminal platform and a straight sheet metal component. The housing is fixedly connected to the wiring terminal platform. At both ends of one side of the wiring terminal platform, there are respectively provided a straight sheet metal limiting groove and a straight sheet metal through hole. On the other side of the wiring terminal platform, there is a glue application groove. One end of the straight sheet metal component is inserted into the straight sheet metal limiting groove, and the other end of the straight sheet metal component passes through the straight sheet metal through hole and is fixedly connected to the wiring terminal platform.

[0007] The beneficial effect of the utility model is that the staff can insert one end of the straight sheet metal component into the straight sheet metal limiting groove of the wiring terminal platform and fixedly connect it to the wiring terminal platform. The staff can pass the other end of the straight sheet metal component through the straight sheet metal through hole of the wiring terminal platform and then apply glue in the glue application groove, so that the other end of the straight sheet metal component is fixedly connected to the wiring terminal platform without gaps.

[0008] Based on the above technical solution, the utility model can also be improved as follows.

[0009] Furthermore, the straight sheet metal component includes a straight sheet metal and a nut. The straight sheet metal includes a limiting portion and a straight sheet portion. One end of the limiting portion is fixedly connected to one end of the straight sheet portion. The other end of the limiting portion is inserted into the straight sheet metal limiting groove and fixedly connected to the terminal post platform.

[0012] The beneficial effect of adopting the above further scheme is that the size of the straight sheet metal limiting groove is the same as the size of the end of the other end of the limiting portion, which can increase the connection stability between the limiting portion and the straight sheet metal limiting groove. The size of the straight sheet metal through hole is the same as the size of the end of the other end of the straight sheet portion, which can prevent the straight sheet portion from shifting when passing through the straight sheet metal through hole and reduce the manual assembly cost.

[0013] Furthermore, the size of the groove is the same as the size of the nut.

[0014] Furthermore, the peripheral side walls of the limiting portion are all serrated.

[0015] The beneficial effect of adopting the above further scheme is that the peripheral side walls of the limiting portion are all serrated, which can prevent the limiting portion from detaching from the straight sheet metal limiting groove and increase the connection stability between the limiting portion and the straight sheet metal limiting groove.

[0016] Furthermore, the end of the other end of the straight sheet portion has a notch.

[0017] The beneficial effect of adopting the above further scheme is that it increases the solder amount on the welding surface of the straight sheet portion, ensures reliable welding, and at the same time, the staff can visually check whether the notch is effectively welded.

[0033] The principles and features of the present utility model will be described below in conjunction with the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0034] As Figures 1-6 shown, this embodiment provides a controller housing with an integrated terminal block, including a housing 1 and a terminal block group. The terminal block group includes a terminal block platform 2 and a straight sheet metal component 3. The housing 1 is fixedly connected to the terminal block platform 2. Straight sheet metal limit grooves 202 and straight sheet metal through holes 203 are respectively arranged at both ends on one side of the terminal block platform 2. A glue application groove 204 is arranged on the other side of the terminal block platform 2. One end of the straight sheet metal component 3 is inserted into the straight sheet metal limit groove 202, and the other end of the straight sheet metal component 3 passes through the straight sheet metal through hole 203 and is fixedly connected to the terminal block platform 2.

[0035] The staff can insert one end of the straight sheet metal component 3 into the straight sheet metal limit groove 202 of the terminal block platform 2 and fixedly connect it to the terminal block platform 2. The staff can pass the other end of the straight sheet metal component 3 through the straight sheet metal through hole 203 of the terminal block platform 2 and then apply glue in the glue application groove 204, so that the other end of the straight sheet metal component 3 is fixedly connected to the terminal block platform 2 without gaps.

[0036] Specifically, the glue application groove 204 is correspondingly located on the back of the straight sheet metal through hole 203.

[0037] Optionally, the housing 1 and the terminal block platform 2 can be integrally injection-molded, or can be connected by means of glue, snap or thread connection, etc.

[0038] Based on the above solution, the straight sheet metal component 3 includes a straight sheet metal 301 and a nut 302. The straight sheet metal 301 includes a limiting portion 3011 and a straight sheet portion 3012. One end of the limiting portion 3011 is fixedly connected to one end of the straight sheet portion 3012. The other end of the limiting portion 3011 is inserted into the straight sheet metal limiting groove 202 and fixedly connected to the terminal post platform 2. The caulking groove 204 is filled with positioning glue. The other end of the straight sheet portion 3012 passes through the straight sheet metal through hole 203 and is located in the caulking groove 204. The straight sheet portion 3012 is fixedly connected to the terminal post platform 2 through the positioning glue. The end of the other end of the straight sheet portion 3012 has a bending portion 3013. The terminal post platform 2 has a groove 201. The nut 302 is located in the groove 201 and is located between the limiting portion 3011 and the terminal post platform 2. The limiting portion 3011 has a through hole.

[0039] The limiting portion 3011 of the straight sheet metal 301 is fixedly connected to the straight sheet metal limiting groove 202, which can limit the limiting portion 3011 and prevent the limiting portion 3011 from displacing. After the other end of the straight sheet portion 3012 passes through the straight sheet metal through hole 203 and is located in the caulking groove 204, a positioning glue is filled into the caulking groove 204 by a dispensing machine, so that the straight sheet portion 3012 is fixedly connected to the terminal post platform 2 without gaps. Subsequently, the bending portion 3013 is bent by a bending machine to bend the straight sheet metal 301 into a U-shaped sheet metal part.

[0040] Specifically, as Figure 3 shown, in this embodiment, the straight sheet metal 301 is L-shaped, and straight sheet metals of other shapes can also be selected according to actual needs.

[0041] Specifically, the groove 201 has a through hole, and the size of the through hole in the groove 201 is the same as the size of the through holes in the nut 302 and the limiting portion 3011.

[0042] Among them, as Figure 1 shown, the straight sheet metal 301 and the nut 302 are two independent components. During installation, the staff needs to first place the nut 302 in the groove 201.

[0043] Alternatively, the top of the nut 302 is fixedly connected to the bottom of the limiting portion 3011 of the straight sheet metal 301 as an independent component.

[0044] Optionally, as Figure 1 shown, the nut 302 is a square nut, and the square nut is a standard part and can be directly purchased, reducing production costs. The staff can also select a hexagonal nut or a special-shaped nut according to actual needs.

[0045] On the basis of the above solution, the size of the straight sheet metal limiting groove 202 is the same as the size of the other end of the limiting portion 3011, and the size of the straight sheet metal through hole 203 is the same as the size of the other end of the straight sheet portion 3012.

[0046] The size of the straight sheet metal limiting groove 202 is the same as the size of the other end of the limiting portion 3011, which can increase the stability of the connection between the limiting portion 3011 and the straight sheet metal limiting groove 202. The size of the straight sheet metal through hole 203 and the other end of the straight sheet portion 3012 can prevent the straight sheet portion 3012 from shifting when passing through the straight sheet metal through hole 203, reducing the manual assembly cost.

[0047] Specifically, the length of the other end of the limiting portion 3011 in the vertical direction is the same as the depth of the straight sheet metal limiting groove 202 in the vertical direction.

[0048] The length of the straight sheet metal through hole 203 in the length direction is the same as the length of the straight sheet portion 3012 in the width direction.

[0049] On the basis of the above solution, the size of the groove 201 is the same as the size of the nut 302.

[0050] On the basis of the above solution, the peripheral side walls of the limiting portion 3011 are all serrated.

[0051] The peripheral side walls of the limiting portion 3011 are all serrated, which can prevent the limiting portion 3011 from detaching from the straight sheet metal limiting groove 202 and increase the stability of the connection between the limiting portion 3011 and the straight sheet metal limiting groove 202.

[0052] On the basis of the above solution, the other end of the straight sheet portion 3012 has a notch 3014.

[0053] Increase the solder amount on the welding surface of the straight sheet portion 3012 to ensure reliable welding. At the same time, the staff can visually check whether the notch 3014 is effectively welded.

[0054] Specifically, as Figure 3 shown, the notch 3014 at the other end of the straight sheet portion 3012 is an inverted U shape, and the inner wall is serrated. It can also be set as a round hole according to actual needs to meet various high-power controllers and improve practicality.

[0055] Among them, the other end of the straight sheet portion 3012, that is, one end of the bending portion 3013, has a notch 3014.

[0056] On the basis of the above solution, the straight sheet metal 301 is a stamping part.

[0057] Stamped parts can achieve large-scale mass production, improve production efficiency, and reduce material management costs.

[0058] On the basis of the above solution, multiple said terminal groups are divided into a long terminal group 4 and a short terminal group 5. The multiple said terminal groups of the long terminal group 4 are arranged at intervals in the horizontal direction and are fixedly connected to the housing 1. The multiple said terminal groups of the multiple short terminal groups 5 are arranged at intervals in the vertical direction and are fixedly connected to the housing 1.

[0059] Specifically, as Figure 4 shown, the long terminal group 4 is arranged in the horizontal direction, and the short terminal group 5 is arranged in the vertical direction.

[0060] According to the actual situation, the long terminal group 4 and the short terminal group 5 can both be arranged in the horizontal direction, or the long terminal group 4 and the short terminal group 5 can both be arranged in the vertical direction, or the long terminal group 4 can be arranged in the vertical direction while the short terminal group 5 is arranged in the horizontal direction.

[0061] On the basis of the above solution, the number of the terminal groups of the long terminal group 4 is greater than the number of the terminal groups of the short terminal group 5.

[0062] Installing the long terminal group 4 and the short terminal group 5 on the housing 1 can improve the practicability of the device.

[0063] Specifically, as Figure 4 shown, the long terminal group 4 includes 3 terminal groups, and the short terminal group 5 includes 2 terminal groups.

[0064] According to the actual situation, the number of the terminal groups in the long terminal group 4 can be set to 4 or 5, etc., but the number of the terminal groups in the long terminal group 4 needs to be greater than the number of the terminal groups in the short terminal group 5.

[0065] On the basis of the above solution, the housing 1 and the terminal post platform 2 are fixedly connected by integral injection molding, gluing, buckling or threading.

[0066] The fixed connection between the housing 1 and the terminal post platform 2 can effectively reduce the storage and assembly costs of the whole machine

[0067] Specifically, the housing 1 has multiple mounting holes 101. Through the mounting holes 101, the staff can assemble the housing 1 with the controller. The assembly steps are simplified, automation can be achieved, and the labor assembly cost can be reduced.

[0068] In this embodiment, when in use, first, place the nut 302 in the groove 201;

[0069] Secondly, insert the limiting portion 3011 of the straight sheet metal piece 301 into the straight sheet metal limiting groove 202 and rivet it with the straight sheet metal limiting groove 202. At the same time, the straight piece portion 3012 of the straight sheet metal piece 301 passes through the straight sheet metal through hole 203 and is located in the glue application groove 204. Fill the positioning glue into the glue application groove 204 through a dispensing machine, so that the straight piece portion 3012 is fixedly connected to the terminal post platform without any gap;

[0070] Finally, use a bending machine to bend the bending portion 3013 of the straight sheet metal piece 301, so that the straight sheet metal piece 301 is bent into a U-shaped sheet metal part, that is, the assembly of the housing 1 is completed.
