Description

Technical Field

[0001] This utility model belongs to the field of connector technology, specifically a connector assembly and server. Background Technology

[0002] In the internal components of a server, cables serve as the medium for signal transmission, and their applications are extensive and crucial. Low-speed signal transmission requires high transmission density, small board size, stable and reliable connections, low cost, and simple and convenient operation. 1.0mm pitch dual-row single-sided unlocking connectors have become the preferred choice for transmitting low-speed signals. Traditional 1.0mm pitch dual-row single-sided unlocking connectors transmit signals in configurations of 2x8pin, 2x10pin, 2x12pin, 2x15pin, 2x18pin, 2x20pin, and 2x25pin (pin: metal rod, in this patent, refers to the metal pins inside the connector; an 8-pin connector refers to a connector with 8 metal pins in a single row, and a 2x8pin connector refers to a connector with 8 metal pins in a double row). (Connectors with low pin counts have no problems in use, but when the number of pins exceeds 2X15, various problems will occur during use. First, the increase in the number of pins leads to an increase in the length of the connector. The locking structure of high-pin-count connectors has the same shape as that of low-pin-count connectors. The ratio of the width of the locking structure to the length of the connector is much lower in high-pin-count connectors than in low-pin-count connectors. In addition, the increase in the length of the connector causes a decrease in the overall rigidity of the connector, which makes high-pin-count connectors prone to the problem of one side tilting up during use. The reliability of high-pin-count connectors cannot be guaranteed.

[0003] In the current server industry, the use of 2x25pin connectors is becoming increasingly widespread due to the growing demand for functional integration. Because of their length, these connectors are highly susceptible to pin detachment during server assembly and maintenance due to cable pulling or vibrations from the server's fan. Pin detachment significantly increases server maintenance costs. Therefore, improving the stability and reliability of low-speed signal lines in servers has always been a challenge for the industry. Utility Model Content

[0004] To address the issue of high-pin-count connectors being prone to pin detachment, which necessitates server maintenance, this invention provides a connector assembly and a server.

[0005] This utility model is achieved through the following technical solution:

[0006] A connector assembly includes a female connector end and a male connector end that can be inserted into the female connector end. The male connector end has a locking panel on its long side. The length of the locking panel is at least one-third of the length of the long side of the male connector end, and the locking panel has a plurality of locking holes along its length. The opening length of the plurality of locking holes is greater than or equal to one-half of the length of the locking panel along its length.

[0007] The long side of the connector female end is provided with a locking pin cantilever that can be adapted to the locking panel. The locking pin cantilever is provided with a claw that can be adapted to the locking hole. One end of the locking pin cantilever is connected to the connector female end, and the locking pin cantilever deforms when the side of the claw facing away from the locking pin cantilever contacts the locking panel until the claw is embedded in the locking hole.

[0008] The length of the locking panel and the ratio of the locking hole to the length of the locking panel help improve the firmness of the male and female connector terminals after mating, preventing easy pin detachment.

[0009] A further improvement of this invention is that the side of the aforementioned claw facing away from the locking pin cantilever is inclined and serves as a claw guide surface capable of deforming the locking pin cantilever. When the female and male ends of the connector are inserted into each other, the inclined claw guide surface engages with the latching panel, reversely pressing the locking pin cantilever to deform it, thus allowing the claw to smoothly enter the latching hole.

[0010] A further improvement of this invention is that the side of the first latch that engages with the latching hole is the top surface of the latch, and the top surface of the latch is an inclined surface that extends upward away from the cantilever side of the locking pin. The inclined surface can cooperate with the inner wall of the latching hole, which helps to prevent the first latch from easily slipping out of the latching hole.

[0011] A further improvement of this utility model is that the cross-section of the top surface of the aforementioned claw has a V-shaped structure with a concave center.

[0012] A further improvement of this invention is that the cross-section of the aforementioned locking pin cantilever is generally L-shaped, the horizontal side of the locking pin cantilever is connected to the connector female end, and the initial state of its vertical side is parallel to the insertion / removal direction of the connector female end; the claw is disposed on the vertical side of the locking pin cantilever. The L-shaped locking pin cantilever has good returnability.

[0013] A further improvement of this invention is that the vertical side of the locking pin cantilever, away from the horizontal side, is provided with a locking pin stop; the connector female end is provided with a limiting baffle adapted to the locking pin stop; the limiting baffle can limit the excessive reset of the locking pin cantilever after deformation, so as to maintain the elasticity of the locking pin cantilever on the connector female end. This helps to avoid the situation where the locking pin cantilever rotates too much due to misoperation, resulting in elastic failure.

[0014] A further improvement of this utility model is that the free end of the aforementioned locking pin cantilever is provided with a pressing panel that extends upward and is higher than the top surface of the connector female end.

[0015] A further improvement of this invention is that a second locking claw is provided on the short side of the female connector end, and the second locking claw is located at the end of the short side of the female connector end away from the locking pin cantilever; a locking groove adapted to the second locking claw is provided on the inner wall of the male connector end. The second locking claw and the first locking claw maintain a balance after combination at both ends in the width direction of the female connector end.

[0016] A further improvement of this invention is that guide protrusions are respectively provided on the other long and short sides of the female connector end; and guide grooves adapted to the guide protrusions are provided on the inner wall of the male connector end. The guide protrusions and guide grooves cooperate to provide guidance for the insertion and mating of the female and male connector ends.

[0017] A server comprising the aforementioned connector assembly.

[0018] As can be seen from the above technical solution, the beneficial effects of this utility model are: the length of the locking panel and the ratio of the length of the locking hole to the length of the locking panel help to improve the firmness of the male and female connectors after insertion and prevent easy pin detachment.

[0027] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0028] like Figure 1-6As shown, this utility model discloses a connector assembly, including a female connector end 10 and a male connector end 20 that can be inserted into the female connector end 10. The long side of the male connector end 20 is provided with a locking panel 21. The length of the locking panel 21 is at least one-third of the length of the long side of the male connector end 20, and the locking panel 21 is provided with a plurality of locking holes 211 along its length direction. The opening length of the plurality of locking holes 211 along a first length is greater than or equal to one-half of the length of the locking panel 21. The first length is along the length direction of the locking panel 21, that is, the opening length of the locking holes 211 along the length direction of the locking panel 21 is greater than or equal to one-half of the length of the locking panel 21. The long side of the connector female end 10 is provided with a locking pin assembly 11. The locking pin assembly 11 includes a locking pin cantilever 111 that can be adapted to the locking panel 21. The locking pin cantilever 111 is provided with a claw 112 that can be adapted to the locking hole 211. One end of the locking pin cantilever 111 is connected to the connector female end 10. When the side of the locking pin cantilever 111 facing away from the locking pin cantilever 111 contacts the locking panel 21, the locking pin cantilever 111 deforms until the claw 112 is embedded in the locking hole 211. The length of the locking panel 21 and the ratio of the length of the locking hole 211 to the length of the locking panel 21 help to improve the firmness of the connector male end 20 and the connector female end 10 after mating, and prevent easy pin detachment.

[0029] like Figure 1 , 2 As shown in Figures 4 and 6, the male connector 20 has an opening centered on its long side. The locking panel 21 corresponds to the opening and protrudes from the outer side of the male connector 20. Both ends of the locking panel 21 in the length direction are connected to the inner wall of the opening. A reinforcing rib is connected between the side of the locking panel 21 facing away from the female connector 10 and the opening. Three locking holes 211 are provided and evenly distributed on the locking panel 21.

[0030] like Figure 1 , 4 As shown in Figure 5, the cross-section of the locking pin cantilever 111 is generally L-shaped. The horizontal side of the locking pin cantilever 111 is connected to the connector female end 10, and the initial state of its vertical side is parallel to the insertion and removal direction of the connector female end 10. The claw 112 is disposed on the vertical side of the locking pin cantilever 111. The L-shaped locking pin cantilever 111 has good return elasticity. The end of the vertical side of the locking pin cantilever 111 near the locking panel 21 is connected to the horizontal side of the locking pin cantilever 111; the claw 112 is disposed on the side of the locking pin cantilever 111 facing away from the connector female end 10.

[0031] like Figure 1 , 4As shown in Figure 5, the vertical end of the locking pin cantilever 111 opposite to the horizontal end is provided with a locking pin stop 114; the connector female end 10 is provided with a limiting baffle 12 adapted to the locking pin stop 114; the limiting baffle 12 can limit the excessive reset of the locking pin cantilever 111 after deformation, so as to maintain the elasticity of the locking pin cantilever 111 on the connector female end 10. This helps to avoid the situation where the locking pin cantilever 111 rotates too much due to misoperation, resulting in elastic failure.

[0032] like Figure 1 , 4 As shown in Figure 5, the free end of the locking pin cantilever 111 is provided with a pressing panel 113 that extends upward and is higher than the top surface of the connector female end 10.

[0033] like Figure 1 and 3 As shown, the side of the claw 112 facing away from the locking pin cantilever 111 is inclined and serves as a claw guide surface 1121, allowing deformation of the locking pin cantilever 111. When the connector female end 10 and connector male end 20 are inserted, the inclined claw guide surface 1121 engages with the locking panel 21, pressing the locking pin cantilever 111 in the opposite direction to deform it, thus allowing the claw 112 to smoothly enter the locking hole 211. The side of the claw 112 that engages with the locking hole 211 is the claw top surface 1122, which is an inclined surface extending upwards away from the locking pin cantilever 111. The inclined surface engages with the inner wall of the locking hole 211; the cross-section of the claw top surface 1122 has a V-shaped structure with a concave center. This helps prevent the claw 112 from easily slipping out of the locking hole 211.

[0034] like Figure 1-2 As shown, the female connector 10 has a second locking claw 14 on its short side, which is located at the end of the female connector 10 away from the locking pin cantilever 111. The male connector 20 has a groove 23 on its inner wall that matches the second locking claw 14. The second locking claw 14 and the first locking claw 112 maintain a balanced combination at both ends of the female connector 10 in the width direction.

[0035] like Figure 1-2 As shown, guide protrusions 13 are respectively provided on the other long and short sides of the female connector 10; the inner wall of the male connector 20 is provided with guide grooves 22 that are adapted to the guide protrusions 13. The guide protrusions 13 and guide grooves 22 cooperate with each other to provide guidance for the insertion and mating of the female connector 10 and the male connector 20.

[0036] A server comprising the aforementioned connector assembly.

[0037] The connector assembly and server described in this utility model, the length of the locking panel 21 and the ratio of the length of the locking hole 211 on the locking panel 21 to the length of the locking panel 21, help to improve the firmness of the connector male end 20 and connector female end 10 after insertion and mating, and prevent easy pin detachment.

[0038] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
