Description

Technical Field

[0001] This invention relates to a bus connector, and more particularly to a bus connector with a replaceable fuse. Background Technology

[0002] Bus bar connectors are primarily used in devices such as server chassis. Because bus connectors are designed to transmit high currents, fuses traditionally used for high current applications are relatively large. To facilitate fuse replacement, even larger fuse holders are required. However, in environments with limited space within server chassis and the need for efficient airflow, it is not feasible to install fuse holders suitable for high currents inside the server chassis.

[0003] On the other hand, to achieve the circuit protection function of the fuse assembly, several fuse assemblies are usually soldered onto the motherboard of the server device. When a fuse assembly burns out and a new fuse assembly needs to be replaced, the external structure of the server device must first be disassembled to remove the motherboard, and then the burned-out fuse assembly must be desoldered before it can be replaced. The entire replacement process is complicated and time-consuming.

[0004] Therefore, how to improve the structural design to place the fuse assembly inside the bus connector for easy replacement, thereby overcoming the above-mentioned defects, has become one of the important issues to be addressed in this field. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a bus connector with a replaceable fuse, which addresses the shortcomings of the prior art.

[0006] To solve the aforementioned technical problems, one technical solution adopted by the present invention is to provide a bus connector with a replaceable fuse, comprising a housing, a first terminal assembly, a second terminal assembly, at least one first cable assembly, at least one fuse assembly, and at least one second cable assembly. Two sockets are formed on a front side of the housing. The first terminal assembly includes a first connector and two first contact springs. The two first contact springs are arranged opposite each other to form a first interface. The first interface communicates with one of the sockets. A first end of the first connector is electrically connected to the two first contact springs. The second terminal assembly is disposed inside the housing, and includes a second connector and two second contact springs. The two second contact springs are arranged opposite each other to form a second interface. The second interface communicates with the other socket. One end of the second connector is electrically connected to the two second contact springs, and the other end of the second connector extends to form a cable connection portion. The at least one first cable assembly includes a first cable body and a cable clamping portion. The cable clamping portion is connected to one side of the first cable body. The first cable body extends from at least one side of the left and right sides of the housing. At least one fuse assembly is connected in series between the cable clamp and the first connector. At least one second cable assembly is electrically connected to the cable connector.

[0007] To solve the aforementioned technical problems, another technical solution adopted by the present invention is to provide a bus connector with replaceable fuses, comprising a housing, a fixing frame, a first terminal assembly, a second terminal assembly, a first cable assembly, two fuse assemblies, and a second cable assembly. The housing includes two sockets. The fixing frame is disposed on opposite sides of the housing on one side forming the two sockets. A receiving portion and a first receiving portion are formed at the bottom of the fixing frame. The fixing frame also has a stepped portion adjacent to the receiving portion. A second receiving portion is formed at the bottom of the stepped portion. A first side outlet is also formed on the opposite side of the fixed frame on the side forming the stepped portion. A slot is also formed between the receiving portion and the stepped portion. The first terminal assembly is disposed inside the housing. The first terminal assembly includes a first connector and two first contact springs. The two first contact springs are disposed opposite each other to form a first interface. The first interface communicates with one of the sockets. One end of the first connector is connected between the two first contact springs, the first connector extends around the stepped portion, and the other end of the first connector is inserted into the slot. The second terminal assembly is disposed inside the housing. The second terminal assembly includes a second connector and two second contact springs. The second connector is connected between the two second contact springs. The two second contact springs are arranged opposite each other to form a second interface. The second interface communicates with another socket. The first cable assembly includes a first cable body and a cable clamping portion connected to one side of the first cable body. The first cable body has a first fixed end, which is disposed at a first side outlet and exposes the cable clamping portion in a first receiving portion. Two fuse assemblies are arranged side by side in the receiving portion, and the two fuse assemblies are connected between the cable clamping portion and the first connector. The second cable assembly includes a second cable body, which has a second fixed end connected to the second connector.

[0008] To address the aforementioned technical problems, another technical solution adopted by the present invention is to provide a bus connector with replaceable fuses, comprising a housing, a fixing frame, a first terminal assembly, a second terminal assembly, a first cable assembly, two fuse assemblies, and a second cable assembly. The housing includes two sockets. The fixing frame is disposed on opposite sides of the housing forming the two sockets. The fixing frame includes a first receiving portion, a second receiving portion, a third receiving portion, and a first through-hole formed between the first receiving portion and the second receiving portion. The first receiving portion and the second receiving portion are located on the same side of the third receiving portion. The first terminal assembly is disposed inside the housing. The first terminal assembly includes a first connector and two first contact springs. The two first contact springs are disposed opposite each other to form a first interface, which communicates with one of the sockets. The first connector is disposed in the first receiving portion. One end of the first connector is connected between the two first contact springs, and the other end of the first connector is inserted into the first through-hole and extends into the third receiving portion. The second terminal assembly is disposed inside the housing. The second terminal assembly includes a second connector and two second contact springs, with the second connector connected between the two second contact springs. The two second contact springs are arranged opposite each other to form a second interface, which communicates with another socket. The first cable assembly includes a first cable body and a cable clamping portion connected to the first cable body. The first cable body has a first fixed end, which is fixed in a first receiving portion. One end of the cable clamping portion is connected to the first fixed end, and the other end is bent and extends to a third receiving portion. Two fuse assemblies are arranged side by side in the third receiving portion, and the two fuse assemblies are connected between the cable clamping portion and the first connector. The second cable assembly includes a second cable body. The second cable body has a second fixed end. The second fixed end is fixed in the second receiving portion and is connected to the second connector.

[0009] One of the beneficial effects of this invention is that the bus connector with replaceable fuses provided by this invention utilizes a fixed frame within the bus connector, and the fixed frame forms at least one receiving portion, such that a first connector of a first terminal assembly, a second connector of a second terminal assembly, and two fuse assemblies are disposed in at least one receiving portion. Compared to the prior art where fuse assemblies are soldered onto the motherboard of a server device, the bus connector with replaceable fuses provided by this invention places the fuse assemblies in at least one receiving portion of the connector, facilitating user replacement, simplifying the replacement process, and improving the efficiency of fuse assembly replacement.

[0047] First Embodiment

[0048] See Figures 1 to 4 As shown, the first embodiment of the present invention provides a bus bar connector M1 with a replaceable fuse, comprising: a housing 1, a fixing frame 2, a first terminal assembly 3, a second terminal assembly 4, at least one first cable assembly 5, at least one fuse assembly 6, and at least one second cable assembly 7. In this embodiment, the number of the first cable assembly 5, the fuse assembly 6, and the second cable assembly 7 are all two. It is worth mentioning that the bus connector M1 provided by the present invention, as well as the bus connectors M2, M3, and M4 in the following embodiments, are mainly side-exit type bus connectors.

[0049] As described above, the housing 1 includes a first housing wall 11, a second housing wall 12, and two wings 13 respectively disposed between the first housing wall 11 and the second housing wall 12. The first housing wall 11 has two first slots 110, the second housing wall 12 has two second slots 120, and each wing 13 has a positioning hole 130 at its bottom. Furthermore, the housing 1 forms two sockets 10 on the front side of the bus connector M1, and the fixing frame 2 is disposed on the opposite side of the side of the housing 1 where the two sockets 10 are formed (i.e., the rear side of the bus connector M1). A first terminal assembly 3 and a second terminal assembly 4 are disposed inside the housing 1. Two fuse assemblies 6 are disposed on the fixing frame 2. One end of each first cable assembly 5 is fixed to the fixing frame 2 and electrically connected to the first terminal assembly 3 and the two fuse assemblies 6. The two first cable assemblies 5 extend from both sides of the fixing frame 2. One end of each second cable assembly 7 is disposed within the fixing frame 2 and electrically connected to the second terminal assembly 4. The two second cable assemblies 7 extend from both sides of the fixing frame 2. (For ease of illustration,) Figures 1 to 3 The first cable assembly 5 and the second cable assembly 7 are omitted.

[0050] See Figure 4 and Figure 5As shown, the first terminal assembly 3 includes a first connector 31 and two first contact springs 32, and the second terminal assembly 4 includes a second connector 41 and two second contact springs 42. The two first contact springs 32 are arranged opposite each other to form a first interface 30, and the two second contact springs 42 are arranged opposite each other to form a second interface 40. The two first contact springs 32 and the two second contact springs 42 are disposed in the housing 1, so that the first interface 30 is connected to one of the sockets 10, and the second interface 40 is connected to the other socket 10.

[0051] See Figures 5 to 7 As shown, the first connector 31 is formed by stamping and bending a metal part. Figure 7 The first connector 31 is presented in its unfolded state before bending. Specifically, the first connector 31 includes a first receiving portion 311 and a connecting portion 312. The first receiving portion 311 is formed by bending two protruding segments 3111, a first segment 3112, a second segment 3113 having a first through hole 3110, and a third segment 3114 having another first through hole 3110.

[0052] See Figure 5 , Figure 6 and Figure 8 As shown, the second connector 41 is also formed by stamping and bending a metal part. Figure 8 The second connector 41 is presented in its unfolded state without being bent. Specifically, the second connector 41 includes a cable connection part 411, two positioning parts 412, and a connecting part 413, with the cable connection part 411 located between the two positioning parts 412. The second connector 411 is electrically connected to the two second contact springs 42 through the connecting part 413.

[0053] See Figure 9 and Figure 10 As shown, the fixing frame 2 forms a first receiving portion 21, a second receiving portion 22, and a third receiving portion 23. The first receiving portion 21 and the second receiving portion 22 are located on the same side of the third receiving portion 23. The fixing frame 2 has a shaft post 2A on one side of the third receiving portion 23, and the fixing frame 2 also includes two abutment portions 26. A positioning post 261 is formed on the top of each abutment portion 26. Therefore, when the fixing frame 2 is disposed on one side of the housing 1, the two positioning posts 261 are respectively inserted into the two positioning holes 130, so that the fixing frame 2 is positioned on the housing 1. The two abutment portions 26 also respectively form two guide grooves 262 (see [reference]). Figure 11 Each guide groove 262 is located on the opposite side of the side where the abutment portion 26 forms the positioning post 261. In addition, the fixing frame 2 also forms a second receiving portion 24 and a third receiving portion 25, both of which are connected to the third receiving portion 23.

[0054] See Figure 11 and Figure 12 As shown, the first connector 31 of the first terminal assembly 3 is inserted along the negative Z-axis direction to be disposed in the first receiving portion 21. The first connector 31 has a first end and a second end. The first end is the connecting portion 312, which is electrically connected to the two first contact springs 32. The second end is the first receiving portion 311 formed by bending, which extends to the third receiving portion 23 and is adjacent to the shaft post 2A. The second connector 41 of the second terminal assembly 4 is inserted along the positive Z-axis direction to be disposed in the second receiving portion 22, and the two positioning portions 412 are respectively disposed in the two guide grooves 262, while the cable connecting portion 411 is located on the back side of the third receiving portion 23.

[0055] Continue reading Figures 1 to 4 As shown, each first cable assembly 5 includes a first cable body 51 and a cable clamping portion 52 connected to one side of the first cable body 51. Two fuse assemblies 6 are disposed in the third receiving portion 23. Each fuse assembly 6 has a first locking hole 60A and a second locking hole 60B at its two ends. Each cable clamping portion 52 includes a through hole 520. The second receiving portion 24 also includes at least one second through hole 240, and the third receiving portion 25 also includes at least one third through hole 250. In this embodiment, there are two first through holes 3110, and one second through hole 240 and one third through hole 250, but the present invention is not limited thereto. Figure 4 As shown, the two fuse assemblies 6 are arranged in series. Therefore, the second locking hole 60B of one fuse assembly 6 overlaps with the first locking hole 60A of the other fuse assembly.

[0056] As described above, the bus connector M1 further includes a first locking member 91, a second locking member 92, and a third locking member 93. The first locking member 91 includes a screw 911 and a nut 912, the second locking member 92 includes a screw 921 and a nut 922, and the third locking member 93 includes a screw 931 and a nut 932. The three nuts 912, 922, and 932 are respectively disposed in the first receiving portion 311, the second receiving portion 24, and the third receiving portion 25.

[0057] Continue reading Figure 2As shown, when the first locking fastener 91, the second locking fastener 92, and the third locking fastener 93 are used to secure the two fuse assemblies 6 and the two first cable assemblies 5, the first locking fastener 91 is connected between the two fuse assemblies 6. Specifically, the screw 911 of the first locking fastener 91 passes through the first locking hole 60A of one fuse assembly 6, the second locking hole 60B of the other fuse assembly 6, and the first through hole 3110 of the second segment 3113, and engages with the nut 912. The second locking fastener 92 is connected between one fuse assembly 6 and one cable clamping part 52, and the third locking fastener 93 is connected between the other fuse assembly 6 and the other cable clamping part 52. Specifically, the screw 921 of the second locking fastener 92 passes through the first locking hole 60A of one fuse assembly 6, the through hole 520 of one cable clamping part 52, and the second through hole 240 of the second receiving part 24, and engages with the nut 922. The screw 931 of the third locking fastener 93 passes through the second locking hole 60B of the other fuse assembly 6, the through hole 520 of the other cable clamping part 52, and the third through hole 250 of the third receiving part 25, and engages with the nut 932. Therefore, the two fuse assemblies 6 are connected in series between the two cable clamping parts 52 and electrically connected to the first connector 31. It should be noted that when the screw 921 engages with the nut 922, it clamps a portion of the thickness of the fixing frame 2 in the second receiving part 24; similarly, when the screw 931 engages with the nut 932, it clamps a portion of the thickness of the fixing frame 2 in the third receiving part 25. Therefore, the second locking fastener 92 and the third locking fastener 93 are not only used to connect the two fuse assemblies 6 and the two cable clamping parts 52, but also to fix the two fuse assemblies 6 and the two cable clamping parts 52 to the fixing frame 2.

[0058] In addition, the bus connector M1 also includes a first cover 81, which has a pivot portion 81A on one side and two first snap-fit ​​pieces 811 on the other side. The first cover 81 is pivotally connected to the shaft post 2A of the fixed frame 2 via the pivot portion 81A, allowing the first cover 81 to pivot about the shaft post 2A to open and close. It is worth mentioning that, as Figure 2 As shown, when the bus connector M1 of the present invention is plugged into the server device, the protrusion 1A of the housing 1 on the first housing wall 11 faces upward (positive Z-axis direction), while the second housing wall 12 of the housing 1 faces downward toward the circuit board of the server device. Moreover, the shaft post 2A and the pivot part 81A are adjacent to the second housing wall 12. Therefore, the opening direction of the first cover 81 is from top to bottom, so that the user will not be blocked by the first cover 81 when replacing the two fuse assemblies 6.

[0059] In addition, please see Figure 1The first cover 81 and the fixed frame 2 form two first side outlets 80A, which are located on the left and right sides of the bus connector M1, respectively. In terms of relative position, the two first side outlets 80A are located on the left and right sides of the housing 1, respectively. Two first cable bodies 51 pass through the two first side outlets 80A, extending out from both sides of the third receiving portion 23. The first cover 81 covers the two fuse assemblies 6 and the two cable clamping portions 52, and has two openings 810 corresponding to the two fuse assemblies 6, improving heat dissipation during operation. Furthermore, when the first cover 81 pivots relative to the fixed frame 2, the two first snap-fit ​​pieces 811 are detachably snapped into the two first slots 110. Furthermore, a pressing member 812 is provided on the same side as the two first card contacts 811, and the user can press the pressing member 812 to open the first cover 81.

[0060] Continue reading Figure 3 , Figure 4 and Figure 11 As shown, each second cable assembly 7 is electrically connected to the cable connection portion 411 of the second connector 41. Each second cable assembly 7 includes a second cable body 71 and a cable joint portion 72 connected to one side of the second cable body 71. The two cable joint portions 72 are electrically connected to the cable connection portion 411 of the second connector 41, respectively. The two second cable bodies 71 extend from both sides of the fixing frame 2. Furthermore, the bus connector M1 also includes a second cover 82, which is disposed on the fixing frame 2 and forms two second side outlets 80B with the fixing frame 2. The two second side outlets 80B are located on the left and right sides of the bus connector M1, respectively. Relative to each other, the two second side outlets 80B are located on the left and right sides of the housing 1, so the two cable joint portions 72 are respectively disposed in the two second side outlets 80B and electrically connected to the cable connection portion 411, and the two second cable bodies 71 extend from the two second side outlets 80B. The second cover 82 covers the cable connection portion 411 and the two cable joint portions 72. The second cover 82 has two second snap-fit ​​pieces 821, which are detachably snapped into the two second slots 120.
