Description

Technical Field

[0001] The utility model relates to the field of connectors, and in particular to a bus connector. Background Art

[0002] Bus connectors are primarily used in electronic devices such as servers and energy storage cabinets to achieve power transmission. Conventional bus connectors typically insert a pair of power terminals, electrically connected to multiple power cables, into an insulating housing. These two opposing power terminals clamp onto the conductive plate of the server or energy storage cabinet, forming an electrical connection for power transmission. However, because the two power terminals require a strong clamping force to prevent them from detaching from the conductive plate during use, disconnecting the bus connector can cause the power terminals to be pulled loose or even detach from the insulating housing, potentially damaging the structure and rendering it unusable.

[0003] Furthermore, in existing bus connectors, the power terminals on both sides are often connected using high-frequency welding or crimping to connect multiple power cables. However, since high-frequency welding can only be performed on one side at a time, once the power cable on one side of the terminal is soldered, the power cable on the other side can become dislodged during soldering. Furthermore, since the power terminals with power cables soldered on both sides are bulky, they also occupy a significant amount of space within the bus connector, shortening the creepage distance and leading to insulation failure.

[0004] In view of this, the inventors have focused on the shortcomings of the above-mentioned prior art, conducted in-depth research and applied scientific theories to try their best to solve the above-mentioned problems, which has become the inventors' improvement goal. Summary of the Invention

[0048] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the present invention.

[0049] The utility model provides a bus connector. Figures 1 to 2 As shown, the bus connector of the present invention includes an insulating body 10 and a pre-assembled component 20 .

[0050] In this embodiment, the insulating body 10 is integrally molded by plastic injection molding, but the present invention is not limited to this. The insulating body 10 can also be made of other insulating materials. The insulating body 10 has a through slot 11 and an inner edge surface 12. The through slot 11 passes through the insulating body 10 along a first direction D1. In this embodiment, the through slot 11 is a rectangular slot passing through the insulating body 10, and the first direction D1 is the front-to-back direction of the insulating body 10 in the figure and the insulating core 21 described later, but the present invention is not limited to this. The inner edge surface 12 surrounds the through slot 11. Specifically, the inner edge surface 12 in this embodiment is composed of four planes.

[0051] The pre-assembled component 20 is inserted into the through slot 11 of the insulating body 10 along the first direction D1, thereby being fixed in the insulating body 10. Figures 2 to 5As shown, the pre-assembled assembly 20 primarily comprises an insulating core 21, a pair of power clamping terminals 22, and a pair of signal terminals 23. The insulating core 21 is generally rectangular and has a pair of engaging grooves 211 and a pair of retaining grooves 212. In this embodiment, the pair of engaging grooves 211 and the pair of retaining grooves 212 are located on opposite left and right sides of the insulating core 21, respectively. However, the present invention is not limited to this. The pair of engaging grooves 211 and the pair of retaining grooves 212 may also be located on the same side of the insulating core 21 or on different sides. Each power clamping terminal 22 is inserted into each engaging groove 211 along a second direction D2, and each power clamping terminal 22 is arranged parallel to each other along a third direction D3. Thus, the insulating core 21 and the inner edge surface 12 jointly cover at least a portion of the outer edge of each power clamping terminal 22, thereby securing each power clamping terminal 22 in place. In this embodiment, the second direction D2 is the left-right direction of the insulating body 10 and the insulating core 21, while the third direction D3 is the up-down direction of the insulating body 10 and the insulating core 21. Therefore, the first direction D1, the second direction D2, and the third direction D3 are all perpendicular to each other. Each signal terminal 23 is disposed within a respective retaining slot 212, parallel to the first direction D1. This allows the insulating core 21 and the inner edge surface 12 to cover at least a portion of the outer edge of each signal terminal 23, thereby securing each signal terminal 23 in place.

[0052] Thus, by pre-assembling the pre-assembled assembly 20 by inserting each power clamping terminal 22 into each slot 211 along the second direction D2 and placing each signal terminal 23 into each slot 212, each power clamping terminal 22 and each signal terminal 23 can be initially secured. The pre-assembled assembly 20 is then inserted into the through slot 11 along the first direction D1 to be secured within the insulating body 10, so that the insulating core 21 and the inner edge surface 12 jointly cover the outer edges of each power clamping terminal 22 and each signal terminal 23. Therefore, the bus connector of the present invention can limit and secure each power clamping terminal 22 and each signal terminal 23, preventing the power clamping terminals 22 or each signal terminal 23 from loosening or falling off when the bus connector is removed, while also effectively enhancing insulation performance.

[0053] To further illustrate, the insulating core 21 has a plurality of hooks 213, and the insulating body 10 has a plurality of barbs 13. Each barb 13 is disposed on the inner edge surface 12 of the insulating body 10. Each barb 13 engages with a hook 213, causing the insulating body 10 to stop the insulating core 21 along the first direction D1, thereby preventing the insulating core 21 from separating from the insulating body 10. Specifically, each hook 213 is disposed at the top and bottom of the insulating core 21, while each barb 13 is disposed at the top and bottom of the inner edge surface 12. Therefore, they do not interfere with the power clamping terminals 22 or signal terminals 23 disposed on the left and right sides of the insulating core 21. In this embodiment, the number of hooks 213 and the number of barbs 13 are both four, and two of the hooks 213 are arranged at intervals along the second direction D2 at the top of the insulating core 21, and the other two hooks 213 are arranged at intervals along the second direction D2 at the bottom of the insulating core 21, two of the barbs 13 are arranged at intervals along the second direction D2 at the top of the inner edge surface 12, and the other two barbs 13 are arranged at intervals along the second direction D2 at the bottom of the inner edge surface 12, but the number of hooks 213 and the number of barbs 13 of the present invention are not limited to this.

[0054] Please see next Figure 2 、 Figure 3 and Figure 6 As shown, in each power clamping terminal 22, the power clamping terminal 22 has a blocking arm 221. The blocking arm 221 extends along the second direction D2 and stops on the outside of the insulating core 21, so that the insulating core 21 stops the power clamping terminal 22 along the first direction D1, thereby preventing the power clamping terminal 22 from being dragged out in the opposite direction of the first direction D1 when the bus connector is unplugged. In addition, each power clamping terminal 22 in this embodiment also has a blocking block 222 extending along the third direction D3 or its opposite direction. The blocking block 222 in each power clamping terminal 22 is also stopped on the outside of the insulating core 21, and the blocking block 222 and the blocking arm 221 are respectively located on different sides of the power clamping terminal 22, thereby further improving the blocking effect while preventing the power clamping terminal 22 from deflecting and swinging with the blocking arm 221 as the fulcrum.

[0055] Refer back Figure 2 and Figure 4As shown, each signal terminal 23 has a pair of positioning tabs 231. The positioning tabs 231 in each signal terminal 23 are spaced apart along the first direction D1 and extend along the third direction D3 or its opposite direction. The insulating core 21 has two pairs of limiting grooves 214, each corresponding to each retaining slot 212. Specifically, each limiting groove 214 in each pair of limiting grooves 214 is spaced apart along the first direction D1 and communicates with the corresponding retaining slot 212. The positioning tabs 231 of each signal terminal 23 are respectively retained within the corresponding limiting groove 214, thereby constraining the insulating core 211 in both the first direction D1 and its opposite direction, thereby preventing the signal terminals 23 from being separated from the insulating core 21.

[0056] Please see next Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the pre-assembled assembly 20 also includes a pair of shielding terminals 24. The front end of the insulating body 10 has a pair of clamping plates 14. Each clamping plate 14 extends along a first direction D1 and is arranged parallel to a third direction D3. The shielding terminals 24 are located on the outside of each clamping plate 14 (i.e., at the top and bottom of the front end of the insulating body 10), while the power clamping terminals 22 are located on the inside of each clamping plate 14, facing each other, and between the shielding terminals 24.

[0057] Each shielding terminal 24 has at least one pressing portion 241 and an inserting portion 242 parallel to the first direction D1. In this embodiment, the pressing portion 241 and the inserting portion 242 are not coplanar, but they may be coplanar in other embodiments. Each pressing portion 241 is attached to the upper and lower sides of the insulating body 10, while each inserting portion 242 is inserted into the insulating body 10 in the opposite direction along the first direction D1, thereby preliminarily fixing each shielding terminal 24 to the insulating body 10. Furthermore, each pressing portion 241 has a first buckle hole 2411, and each inserting portion 242 has a second buckle hole 2421. The insulating body 10 has at least one pair of first clips 15. Each first clip 15 is arranged on the upper and lower sides of the insulating body 10 corresponding to each clamping plate 14, and each first clip 15 is snapped into each first buckle hole 2411. The insulating core 21 has a pair of second clips 215. Each second clip 215 is disposed on opposite upper and lower sides of the insulating core 21, and each second clip 215 is snapped into a second snap hole 2421. Thus, the first clip 15 of the insulating body 10 and the second clip 215 of the insulating core 21 are snapped into the first snap hole 2411 and the second snap hole 2421 of the shielding terminal 24, respectively, thereby further effectively securing the shielding terminal 24 to the insulating body 10 and preventing it from detaching. In this embodiment, each shielding terminal 24 has two pressing portions 241 spaced apart along the second direction D2, and two pairs of first clips 15 are spaced apart along the second direction D2. Thus, by snapping four first clips 15 into four first snap holes 2411, the snapping effect is significantly improved, but the present invention is not limited to this.

[0058] To further illustrate, each shielding terminal 24 also has a plurality of elastic shielding arms 243 and an abutting piece 244. In each shielding terminal 24, the abutting piece 244 is attached to the insulating body 10. The pressing portion 241 and the inserting portion 242 extend from the abutting piece 244 in the opposite direction of the first direction D1. Each shielding arm 243 extends from the abutting piece 244 in the first direction D1. More specifically, the abutting piece 244 is substantially perpendicularly connected to each shielding arm 243, the pressing portion 241, and the inserting portion 242.

[0059] Refer back Figures 1 to 3 and Figures 5 to 8As shown, each power clamping terminal 22 includes a folded plate 223, a joint plate 224, and a plurality of elastic clamping arms 225. The folded plate 223 includes a first plate 2231, a second plate 2232, and a connecting rib 2233. The connecting rib 2233 is bent in a generally U-shape to connect the first plate 2231 and the second plate 2232, thereby attaching the first plate 2231 to the second plate 2232. Each elastic clamping arm 225 extends from the folded plate 223 and generally along the first direction D1. Specifically, a portion of the elastic clamping arms 225 extends from the front end of the first plate 2231, while another portion of the elastic clamping arms 225 extends from the front end of the second plate 2232. This allows the elastic clamping arms 225 of the first plate 2231 and the elastic clamping arms 225 of the second plate 2232 to be arranged in a staggered row. The joining plate 224 is stacked and affixed to the second plate 2232, and the joining plate 224 is flush with the first plate 2231. Specifically, the first plate 2231 and the joining plate 224 are closely adjacent to each other, and the combined shape of the two corresponds to the shape of the second plate 2232.

[0060] In addition, the pre-assembled component 20 also includes a plurality of first power cables 25, a plurality of second power cables 26, and a pair of signal lines 27. Each first power cable 25 is welded to the second plate 2232 and the connecting plate 224 of one of the power clamping terminals 22. Specifically, in the power clamping terminal 22, a portion of the first power cables 25 is welded to a side of the second plate 2232 away from the connecting plate 224 and away from the elastic clamping arm 225, while another portion of the first power cables 25 is welded to the connecting plate 224. In other words, each first power cable 25 is welded to the upper and lower sides of the end of the power clamping terminal 22. Each second power cable 26 is welded to the second plate 2232 and the connecting plate 224 of the other power clamping terminal 22. Specifically, in the power clamping terminal 22, a portion of the second power cable 26 is welded to a side surface of the second plate 2232 away from the connecting plate 224 and away from the elastic clamping arm 225, and another portion of the second power cable 26 is welded to the connecting plate 224, that is, each second power cable 26 is welded to the upper and lower sides of the end of the power clamping terminal 22. Each signal line 27 is electrically connected to the end of each signal terminal 23. In each power clamping terminal 22, the connecting plate 224 is fixed to the second plate 2232 by riveting, welding, locking or bonding. In this embodiment, the connecting plate 224 is fixed to the second plate 2232 by riveting, but the present invention is not limited to this.

[0061] Thus, because each power clamping terminal 22 connects to each first power cable 25 or each second power cable 26, the structure is divided into a second plate 2232 and a connecting plate 224. Therefore, the second plate 2232 and the connecting plate 224 can be individually high-frequency welded, resulting in a uniform distribution of weld space and thus optimizing creepage distance. Furthermore, after high-frequency welding or crimping, the second plate 2232 and the connecting plate 224 are then fixed together by riveting, welding, locking, or gluing to form an upper and lower stacked structure. This allows each first power cable 25 or each second power cable 26 to be distributed above and below the power clamping terminal 22, effectively ensuring the strength of the overall structure and the stability of current transmission.

[0062] The bus connector of the present invention inserts each power clamping terminal 22 into each embedding groove 211 along the second direction D2 so that the insulating inner core 21 and the inner edge surface 12 jointly cover the outer edge portion of each power clamping terminal 22, and arranges each signal terminal 23 in each clamping groove 212 so that the insulating inner core 21 and the inner edge surface 12 jointly cover the outer edge portion of each signal terminal 23. Therefore, each power clamping terminal 22 and each signal terminal 23 can be limited and fixed, thereby preventing each power clamping terminal 22 or each signal terminal 23 from loosening and falling off when the bus connector is pulled out, and at the same time effectively enhancing the insulation performance.

[0063] In summary, the above disclosure of the present invention is intended to enable those skilled in the art to clearly understand the technical content of the present invention and implement it accordingly, and is not intended to limit the scope of patent protection of the present invention. In addition, the present invention may of course have many other embodiments not listed here. Without departing from the spirit and essence of the present invention, those skilled in the art should be able to develop various corresponding changes and modifications based on the present invention, and such corresponding changes and modifications should fall within the scope of protection of the patent applied for the present invention.
