Description

Technical Field

[0001] The utility model relates to the technical field of wiring sockets, in particular to a split upper glue-dotting wiring socket and a controller. Background Art

[0002] Electric bicycles, electric motorcycles and other electric vehicles are equipped with a controller for controlling electric vehicles. The glue slot of the commonly used glue terminal block on the aluminum substrate of the controller is generally located at the bottom of the terminal block (such as Figure 1 ), when using, you need to fill the dispensing tank with silicone first, wait for it to solidify, and then weld the terminal block to the aluminum substrate. Since component welding generally uses reflow soldering, the preheating temperature is as high as 280°C. Ordinary silicone cannot be used under this high temperature condition, and problems such as melting, cracking, yellowing and discoloration will occur. Special high-temperature resistant silicone can be used for dispensing of this type of terminal block, but the cost is too high. In order to prevent the silicone from melting and cracking during the welding process, it can also be dispensed after the welding is completed, but the dispensing tank of the terminal block is located at the bottom. The dispensing tank is blocked after the welding is completed, and the automatic dispensing machine cannot be used for dispensing. It can only be manually injected into the dispensing tank using a manual glue gun. The injection amount cannot be guaranteed to be consistent, and the silicone in the glue tank is prone to form voids, affecting the sealing effect. At the same time, manual dispensing is inefficient and has poor consistency.

[0003] Therefore, it is necessary to provide a low-cost terminal block technical solution that can be dispensed using an automatic dispensing machine and can be dispensed after being welded to an aluminum substrate. Utility Model Content

DETAILED DESCRIPTION

[0042] In order to deepen the understanding of the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and embodiments. The embodiments are only used to explain the present invention and do not limit the scope of protection of the present invention.

[0043] Please refer to Figures 2 to 10 The utility model provides a split upper glue-dispensing terminal block, comprising a terminal block plastic part 11, a nut 12, a conductive sheet 13 and a side patch 14;

[0044] The side patch 14 is embedded in the side opening 111 of the wiring seat plastic part 11, and adopts a transition fit with the wiring seat plastic part 11, and a gap is left between its upper edge and the side of the wiring seat plastic part 11;

[0045] The interior of the terminal block plastic part 11 is provided with an accommodating cavity;

[0046] The accommodating cavity is divided into an upper nut groove 112 and a lower glue dispensing groove 113;

[0047] The nut 12 is placed in the nut groove 112;

[0048] The glue dispensing groove 113 is connected to the notch;

[0049] A first connector 131 and a second connector 132 are provided on both sides of the conductive sheet 13;

[0050] The conductive sheet 13 is arranged through the bottom surface of the terminal block plastic part 11;

[0051] The first joint 131 is located on the upper surface of the nut 12;

[0052] The second connector 132 is located on the outer side of the bottom surface of the wiring seat plastic part 11;

[0053] The first joint 131 is provided with a first through hole 1301 corresponding to the center hole 121 of the nut 12;

[0054] The first through hole 1301 is connected to the glue dispensing groove 113 through the middle hole 121 .

[0055] In this embodiment, the terminal block plastic part 11 can be made of conventional materials such as modified poly (p-phenylene terephthalamide) (PPA), polyphenylene sulfide (PPS), polyethylene terephthalate (PBT), nylon (NYLON), acrylonitrile-butadiene-styrene copolymer (ABS) and polycarbonate (PC), and its specific shape can be confirmed according to actual implementation needs. The nut 12 can be a conventional nut such as a round nut, a square nut, a hexagonal nut. The conductive sheet 13 can be made of metal materials such as copper, aluminum, and stainless steel. The side patch 14 can be made of a material similar to the terminal block plastic part 11 or other insulating materials. During the specific implementation, the terminal block plastic part 11, nut 12, conductive sheet 13 and side patch 14 and other components can be prepared first. A through groove 114 is provided at the bottom of the terminal block plastic part 11. The nut 12 can be a square nut, and the nut slot 112 is square. The conductive sheet 13 is a copper sheet. During assembly, the side patch 14 is embedded in the side opening 111 of the terminal block plastic part 11, and a transition fit is adopted between the terminal block plastic part 11. The nut 12 is placed in the nut slot 112 of the terminal block plastic part 11, and the copper sheet, i.e. the conductive sheet 13, is pressed into the terminal block plastic part 11 and passed through the through slot 114, and then the two ends of the copper sheet are bent to form a first joint 131 and a second joint 132 (it is also possible to bend first to form a plane, i.e. the first joint 131, and then the copper sheet, i.e. the conductive sheet 13, is passed through the through slot 114 and pressed into the terminal block plastic part 11, and then bend again to form another plane, i.e. the second joint 132.). After the terminal block is assembled, it is welded to the aluminum substrate, and the automatic glue dispensing machine is set to the glue output, and the glue outlet position is aligned with the center hole of the terminal block, i.e. the first through hole 1301 of the first joint 131, and then the corresponding glue dispensing operation is performed to complete the glue injection.

[0056] It should be noted that the gap between the upper edge of the side patch 14 and the side of the terminal block plastic part 11 is the exhaust port and window position left after the side patch 14 and the terminal block plastic part 11 are assembled. Figure 3 、 Figure 5 、 Figure 9 、 Figure 10 During the dispensing process, the air during dispensing can be discharged in time through the gap to avoid the formation of cavities inside the terminal block that affect the waterproof effect; it also serves as a window, making it convenient to adjust the amount of glue injected and prevent overflow or insufficient glue dispensing.

[0057] In a possible implementation, the nut 12 is a square nut;

[0058] The nut slot 112 is a square slot that matches the square nut.

[0059] In this embodiment, Figure 2 The 2-position terminal block shown and Figure 4In the shown two-position terminal block, the terminal block plastic part 11 has the nut 12 and the nut slot 112 designed to be square, which can improve the stability of the nut 12 and prevent it from rotating.

[0060] In a possible implementation, the first joint 131 and the second joint 132 are bent.

[0061] In this embodiment, by bending the two ends of the conductive sheet 13, a first connector 131 and a second connector 132 can be formed at the two ends of the conductive sheet 13, thereby realizing an integrated design between the conductive sheet 13, the first connector 131, and the second connector 132, which not only increases stability but also reduces the complexity of the manufacturing process of the terminal block.

[0062] In a possible implementation, a bending angle between the first joint 131 and the second joint 132 is 90°.

[0063] In this embodiment, when the first connector 131 is bent at a 90° angle, the bend of the first connector 131 can fit more closely with the nut 12, reducing space and improving stability. When the second connector 132 is bent at a 90° angle, it is easier to mount the terminal block on the aluminum substrate, reducing the complexity of the structure on the aluminum substrate that supports the terminal block.

[0064] In one possible implementation, Figure 2 、 Figure 3 、 Figure 6 、 Figure 9 , the bending directions of the first joint 131 and the second joint 132 are in the same direction.

[0065] In this embodiment, the first joint 131 and the second joint 132 have the same bending direction.

[0066] In one possible implementation, Figure 5 、 Figure 7 、 Figure 10 , the bending directions of the first joint 131 and the second joint 132 are opposite.

[0067] In this embodiment, the first joint 131 and the second joint 132 are bent in opposite directions.

[0068] In one possible implementation, Figure 6 、 Figure 7 、 Figure 9 、 Figure 10 A second through hole 1302 is provided on the conductive sheet 13 at the position of the glue dispensing groove 113 .

[0069] In this embodiment, the second through hole 1302 can be a conventional circular hole. It should be pointed out that when the conductive sheet 13 passes through the through groove 114 on the bottom surface of the terminal block plastic part 11, a blocking surface will be formed in the middle of the glue dispensing groove 113. The blocking surface separates the glue dispensing groove 113 into an inner and outer part. The inner and outer parts are connected by the gaps on the two edges of the blocking surface. When the silicone gel is dispensed, it does not flow smoothly from the inside of the glue dispensing groove 113 to the outside, and it may also cause the air in the glue dispensing groove 113 to be unable to be completely discharged. By providing the second through hole 1302, the silicone gel can flow from the inside of the glue dispensing groove 113 to the outside through the second through hole 1302 and the gaps on the two edges of the blocking surface at the same time, which is conducive to shortening the injection time and is also conducive to discharging the air in the glue dispensing groove 113.

[0070] In one possible implementation, Figures 5 to 7 , a third through hole 1303 is provided on the second joint 132 .

[0071] In this embodiment, the third through hole 1303 can be a conventional circular hole. By providing the third through hole 1303, the firmness and safety of the conductive sheet 13 when connected to the outside can be further increased.

[0072] In a possible implementation, the conductive sheet 13 is a copper sheet.

[0073] In this embodiment, when a copper sheet is used as the conductive sheet 13 , it can be ensured that the conductive sheet 13 has good conductive properties, and since the manufacturing process of the copper sheet is simple, the production cost can also be effectively reduced.

[0074] The utility model also provides a controller provided with the wiring socket as described above.

[0075] In this embodiment, the controller can be a controller for controlling an electric vehicle, and internally includes an aluminum substrate using the aforementioned terminal block. This aluminum substrate utilizes a soldering-first, then glue-dispensing process. In a specific implementation, the assembled terminal block is first soldered to the corresponding position of the aluminum substrate body, perhaps using reflow soldering. An automatic glue dispenser is then set to a desired glue output, with the dispenser aligned with the center hole of the terminal block, i.e., first through-hole 1301. Glue is then dispensed to complete the process, and the aluminum substrate is finally installed within the controller.

[0076] The above embodiments should not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent conversion fall within the protection scope of the present invention.
