Description

Technical Field

[0001] This invention belongs to the field of connector technology, and specifically refers to a high-current connector. Background Technology

[0002] With the continuous development and progress of cutting-edge technologies such as 5G and artificial intelligence, the demand for servers in these fields has increased significantly. People are increasingly relying on networks for communication in their work and daily lives, leading to a continuous surge in network data volume. In today's society, the demand for high-density servers is growing, and connectors play an indispensable role among the internal components of these high-density servers.

[0003] In specific applications, when multiple connectors need to be connected in series on the same set of connecting lines, the wire routing will perpendicularly intersect the connector insertion direction. Standard connector terminals typically use a triangular layout, causing two terminals to overlap laterally. This design prevents the live, neutral, and ground wires from connecting side-by-side to the terminals, leading to interference between the wires. Forcing a connection can also cause the terminals to bend or deform due to the reaction force of the wires, potentially resulting in adverse consequences. Summary of the Invention

[0004] The main objective of this invention is to provide a high-current connector that solves the problems existing in the prior art, allowing more connectors to be connected in series within the server rack.

[0005] To achieve the above objectives, the solution of the present invention is: A high-current connector includes a housing and three terminals. The surface of the housing is provided with terminal holes for inserting the terminals. Each terminal includes a head, a connecting portion, and a tail portion connected in sequence. The head of the terminal is embedded in the corresponding terminal hole for connection with an external connector. The connecting portion and the tail portion of the terminal protrude from the surface of the housing. The length, width, and height of the connector are defined as the Z, Y, and X axes, respectively. There are two terminals, and the head and tail portions of the terminals have a greater than zero offset in the X-axis direction parallel to the surface of the housing at the end of the connector. The offsets of the three terminals are different.

[0006] A high-current connector includes a housing, a first terminal, and a second terminal. The surface of the housing has at least one terminal hole. The first terminal fits into the terminal hole and includes a first head, a first connecting portion, and a first tail. The two ends of the first connecting portion are respectively connected to the first head and the first tail via a first bend. The total length of the first terminal is defined by the sum of the lengths of the first head, the first connecting portion, and the first tail. The second terminal fits into the terminal hole and includes a second head, a second connecting portion, and a second tail. The two ends of the second connecting portion are respectively connected to the second head and the second tail via a second bend. The total length of the second terminal is defined by the sum of the lengths of the second head, the second connecting portion, and the second tail. The length of the first connecting portion is greater than the length of the second connecting portion, and the total length of the first terminal is greater than the total length of the second terminal.

[0007] The connector's dimensions are set within the range of 27±20% mm in length, 31±20% mm in width, and 23±20% mm in height.

[0008] With the centerline of the terminal hole as a reference, among the three terminal holes arranged in a quality pattern, the distance between a single terminal hole and any one of the two parallel terminal holes in the width direction of the housing is 7±20% mm, the distance between the two parallel terminal holes in the width direction of the housing is 14±20% mm, and the distance between a single terminal hole and the two parallel terminal holes in the height direction of the housing is 7±20% mm.

[0009] Preferably, the tail of the first terminal extends beyond the housing in a top-down view of the connector.

[0010] The surface of the housing is provided with latches that cooperate with the cabinet to achieve fixation.

[0011] Preferably, the latch is a trapezoidal protrusion protruding from the surface of the housing.

[0012] After adopting the above technical solution, the present invention has the following technical effects: This invention designs offsets between the head and tail of each connector terminal, allowing each terminal to have different offsets. From the side view of the connector, the tails are staggered, preventing interference between the wires connected to each terminal and providing a certain margin of error during installation. This allows for the installation of more connectors in series within the server rack. Furthermore, this invention only improves the shape of the terminals without changing the housing or its corresponding manufacturing process, resulting in lower costs. Attached Figure Description

Detailed Implementation

[0025] To further explain the technical solution of the present invention, the present invention will be described in detail below through specific embodiments.

[0026] refer to Figure 1-6As shown in the first embodiment of the present invention, a high-current connector is disclosed, including a housing 1 and three terminals; the surface of the housing 1 is provided with terminal holes 11 for terminal insertion; the terminal includes a head, a connecting part and a tail connected in sequence; the head of the terminal is embedded in the corresponding terminal hole for connection with an external connector. Here, the connector of the present invention can be either a male connector or a female connector. The head of the terminal is located in the insertion hole of the housing for connection with another connector; the connecting part and the tail of the terminal are exposed from the surface of the housing; the length, width and height of the connector are defined as the Z, Y and X axes, respectively. There are two terminals, and their heads and tails have a greater than zero offset in the X axis direction parallel to the housing surface at the end of the connector, and the offsets of the three terminals are different.

[0027] Through the above solution, the present invention designs an offset between the head and tail of each terminal of the connector, so that each terminal has a different offset; from the side view of the connector, the position of each tail is staggered, so that the wires connected to each terminal no longer interfere with each other, and there is a certain fault tolerance during installation, which ultimately allows more connectors to be connected in series in the server rack; at the same time, the present invention only improves the shape of the terminal without changing the housing 1 and its corresponding manufacturing process, so the cost is lower.

[0028] In the first embodiment, the high-current connector includes at least a housing 1, a first terminal 2, and a second terminal 3. The surface of the housing 1 is provided with at least one terminal hole 11. The housing 1 can be made of insulating plastic material and integrally formed by injection molding process, and is provided with three sets of terminal holes 11 arranged in a triangular pattern for each terminal to be embedded.

[0029] The first terminal 2, which is fitted into the terminal hole 11, includes a first head 21, a first connecting portion 22, and a first tail 23. The two ends of the first connecting portion 22 are respectively connected to the first head 21 and the first tail 23 via a first bend 24. The total length of the first terminal 2 is defined by the sum of the lengths of the first head 21, the first connecting portion 22, and the first tail 23. Here, the first bend 24 forms a 90° angle between the first head 21 and the first connecting portion 22, and between the first connecting portion 22 and the first tail 23. Therefore, the length of the first connecting portion 22 determines the offset between the first head 21 and the first tail 23, and the same applies to the second connecting portion 32 described below.

[0030] The second terminal 3 is fitted into the terminal hole 11. This terminal hole 11 can be the same terminal hole 11 as the first terminal 2, with the two isolated by an insulating design, or it can be a different terminal hole 11. The second terminal 3 includes a second head 31, a second connecting portion 32, and a second tail 33. The two ends of the second connecting portion 32 are respectively connected to the second head 31 and the second tail 33 through a second bend 34. The total length of the second terminal 3 is defined by the sum of the lengths of the second head 31, the second connecting portion 32, and the second tail 33.

[0031] The length of the first connecting part 22 is greater than the length of the second connecting part 32, so that the first tail part 23 and the second tail part 33 are misaligned, and the total length of the first terminal 2 is greater than the total length of the second terminal 3.

[0032] refer to Figure 2 , 3 As shown, the size range of the above connectors is set as follows: The length L is 27±20% mm, the width W is 31±20% mm, and the height H is 23±20% mm.

[0033] refer to Figure 6 As shown, with the centerline of terminal hole 11 as the reference, among the three terminal holes 11 arranged in a quality pattern, the distance D1 between any one of the individual terminal hole 11 and the two parallel terminal holes 11 in the width direction of housing 1 is 7±20% mm, the distance D2 between the two parallel terminal holes 11 in the width direction of housing 1 is 14±20% mm, and the distance D3 between the individual terminal hole 11 and the two parallel terminal holes 11 in the height direction of housing 1 is 7±20% mm.

[0034] Furthermore, the first tail portion 23 of the first terminal 2 extends beyond the housing 1 from the top view of the connector, so that the first tail portion 23 protrudes from the side of the housing 1.

[0035] The surface of the aforementioned housing 1 is provided with a latch 12 that cooperates with the cabinet to achieve fixation.

[0036] Furthermore, the aforementioned latch 12 is a trapezoidal protrusion protruding from the surface of the housing 1, rather than the elastic claw in conventional technology, which can lock the connector in the cabinet and prevent it from loosening.

[0037] refer to Figure 7-11As shown, this is a second embodiment of the present invention, disclosing another high-current connector, including a housing 1, and a positive terminal 4, a negative terminal 5, and a ground terminal 6 that are mated to the surface of the housing 1; the exposed lengths of the positive terminal 4 and the negative terminal 5 on the housing surface are greater than the exposed lengths of the ground terminal 6 on the housing surface; both the positive terminal 4 and the negative terminal 5 are provided with reinforcing ribs 41 and 51, and the exposed portions of the positive terminal 4 and the negative terminal 5 on the housing surface expand obliquely in a V-shape towards both sides of the housing 1 (see...). Figure 8 In the routing direction, the grounding terminal 6 is located between the positive terminal 4 and the negative terminal 5, and is provided with a C-type interface 61 for connecting the grounding cable in series.

[0038] In the second embodiment above, the terminals are designed to resemble teardrop holes, which allows multiple connectors to be arranged side by side in the routing direction and connected in series via copper pillars.

[0039] The above embodiments and figures are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
