Description

Technical Field

[0001] This invention relates to the field of connector technology, and more particularly to a standard-sized, high-power-density, anti-collision PIN crimp terminal connector. Background Technology

[0002] like Figure 1 As shown, the first type of connector in the related technology includes a power terminal with a row of contact areas. The current-carrying cross-section is small and it is difficult to meet the 4500W power requirement. If the 4500W power is forcibly output, the temperature rise will exceed 30°C, and it may even cause a fire, which is very dangerous. In addition, the finished terminal is exposed. When mating, the mating gold finger plate may touch the terminal head, causing pin failure.

[0003] like Figure 2 As shown, the first type of connector in the related technology includes power terminals. Each power terminal may include an outer row terminal and an inner row terminal. The outer row terminal and the inner row terminal have the same width. The spring tab protrusion of the inner row terminal is completely blocked by the spring tab protrusion of the outer row terminal. The spring tab protrusion of the inner row terminal is retracted outward or even missing, which is undetectable. If it flows out to the customer, it will cause poor contact or open circuit. It will transfer all the transmission current pressure to the outer row terminal, which can easily cause temperature rise or even fire, which is very dangerous. Moreover, the finished terminal protrudes, and when mating, the mating gold finger plate may touch the terminal head, causing pin failure. Summary of the Invention

[0008] In some embodiments, all the first spring pieces have the same dimension along the length direction of the main colloid; And / or, all the second springs have the same dimensions along the length of the main colloid.

Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0018] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0019] See Figures 3 to 11 As shown, this invention discloses a standard-size, ultra-high power density, anti-mating PIN crimp connector, primarily used in AI training servers and GPU clusters, high-performance computing nodes, and high-end storage and network devices. In some embodiments, this standard-size, ultra-high power density, anti-mating PIN crimp connector may be, but is not limited to, a standard-size CRPS connector. In some embodiments, this standard-size, ultra-high power density, anti-mating PIN crimp connector may also be defined as a standard-size, ultra-high power density, anti-mating PIN crimp connector.

[0020] The ultra-high power density anti-mating PIN crimp terminal connector with this standard size can be a standard size, which is 69.90mm in length. Width 9.50 mm Height 15.50 mm, card insertion depth 10.00 mm (e.g.) Figure 4 and Figure 6As shown, this standard-sized, ultra-high power density anti-mating crimped PIN connector can have a fixed number of pins (12 power pins and 14 signal pins). This standard-sized, ultra-high power density anti-mating crimped PIN connector has the function of transmitting current and signals. In this application, ultra-high power refers to power of 4500W or higher.

[0021] See Figures 3 to 11 As shown, the standard-sized, ultra-high power density anti-collision PIN crimp terminal connector includes a main body 10, a plurality of power terminal groups 20 and a plurality of signal terminal groups 30; the plurality of power terminal groups 20 and the plurality of signal terminal groups 30 are all mounted on the main body 10.

[0022] Each power terminal group 20 includes two power terminal assemblies 21, which are symmetrically arranged along the width direction of the main body 10, and the space between the two power terminal assemblies 21 forms a clamping space 20a; each power terminal assembly 21 includes an outer power terminal 211 and an inner power terminal 212, the inner power terminal 212 being located inside the outer power terminal 211 and spaced apart from the outer power terminal 211; the upper end of the outer power terminal 211 is located above the upper end of the inner power terminal 212.

[0023] like Figure 8 and Figure 9 As shown, in some embodiments, each external power terminal 211 includes a first sheet-like body 2111, the upper end of which is provided with four first spring tabs 2112, the four first spring tabs 2112 extending at intervals along the length direction of the main colloid 10; each first spring tab 2112 includes an S-shaped segment 21121, the S-shaped segment 21121 is inclined from bottom to top toward one side of the internal power terminal 212, the inner side of the lower part of the S-shaped segment 21121 forms a clearance space 2112a; the innermost side of the S-shaped segment 21121 forms a first contact surface 21121a.

[0024] Each inner power terminal 212 includes a second sheet-like body 2121. The upper end of the second sheet-like body 2121 is provided with three second spring tabs 2122. The three second spring tabs 2122 extend at intervals along the length of the main colloid 10. Each second spring tab 2122 includes a first curved section 21221. The first curved section 21221 extends from bottom to top from the side away from the S-shaped section 21121 towards the side closer to the S-shaped section 21121, and is located in the clearance space 2112a. The innermost side of the first curved section 21221 forms a second contact surface 21221a. The first contact surface 21121a and the second contact surface 21221a are on the same plane, with the second contact surface 21221a located below the first contact surface 21121a. Here, "the same plane" can mean that the first contact surface 21121a and the second contact surface 21221a are completely or approximately on the same plane in the longitudinal direction, as long as the gold finger plate 100 can simultaneously contact the first contact surface 21121a and the second contact surface 21221a. Figure 7 As shown.

[0025] In this application, each external power terminal 211 includes four first spring contacts 2112, and each internal power terminal 212 includes three second spring contacts 2122. When combined, they can form a staggered arrangement (which can be combined). Figure 10 As shown, the testing device illuminates the top of the main colloid 10, ensuring that each of the four first spring tabs 2112 and three second spring tabs 2122 is illuminated, allowing for accurate monitoring of the spring tab height. This ensures reliable contact of the finished product, preventing poor contact and open circuits in the inner power supply terminals 212, thus improving safety and enhancing product competitiveness. Of course, in other embodiments, the number of first spring tabs 2112 for each outer power supply terminal 211 can be any number of three or four, and the number of second spring tabs 2122 for each inner power supply terminal 212 can be any number of two or three, as long as the first spring tabs 2112 and second spring tabs 2122 are staggered. No specific limitations are imposed here.

[0026] In addition, the upper part of the external power terminal 211 is designed in an "S" shape. Within the narrow height space (15.50mm high, gold finger plate insertion depth 10.0mm), it leaves room for the deformation of the head of the internal power terminal 212 (i.e., clearance space 2112a) and the adhesive space for the main adhesive 10 to cover the head of the external power terminal 211, effectively avoiding the risk of PIN breakage when inserting the gold finger plate 100.

[0027] The upper end of the main colloid 10 is provided with a insertion hole 11, which communicates with the clamping space 20a. The upper end of the external power terminal 211 is located below the upper wall of the main colloid 10, and the upper end (or head) of the external power terminal 211 is positioned away from the insertion hole 11. The upper end (or head) of the external power terminal 211 is spaced apart from the upper wall of the main colloid 10, leaving a gap between them. Here, "away" means that the upper end of the external power terminal 211 is not exposed in the insertion hole 11, such as... Figure 5 As shown.

[0028] In this application, the ultra-high power density anti-collision PIN crimp terminal connector of this standard size has the following advantages: (1) The power terminals are divided into upper and lower contacts. Each power terminal group 20 may include two first contact surfaces 21121a and two second contact surfaces 21221a, for a total of four contact surfaces, providing sufficient contact area cross-sectional area to ensure current carrying capacity and meet the requirement that the connector temperature rise does not exceed 30°C when outputting 4500W power safely, significantly improving safety and thereby enhancing product competitiveness.

[0029] (2) The upper end of the external power terminal 211 is set away from the insertion hole 11 of the main adhesive 10. The upper end face of the main adhesive 10 covers the adhesive space of the head of the external power terminal 211, effectively avoiding the risk of PIN breakage when inserting the gold finger board 100.

[0030] In this application, a power terminal assembly 21 can also be defined as a 1-pin power terminal, which includes 1 external power terminal 211 and 1 internal power terminal 212. In this application, the number of power terminal groups 20 can be six, that is, twelve power terminal assemblies 21.

[0031] like Figure 8 and Figure 9 As shown, in some embodiments, each first spring piece 2112 includes a first inclined section 21122, the lower end of which is connected to the first sheet-like body 2111, and the upper end of which is connected to the lower end of the S-shaped section 21121; the first inclined section 21122 is inclined from bottom to top toward one side of the inner row power terminal 212.

[0032] like Figure 8 and Figure 9 As shown, in some embodiments, each second spring 2122 includes a second curved section 21222 and a second inclined section 21223.

[0033] The lower end of the second curved segment 21222 is connected to the second sheet-like body 2121, the upper end of the second curved segment 21222 is connected to the lower end of the second inclined segment 21223, and the upper end of the second inclined segment 21223 is connected to the lower end of the first curved segment 21221.

[0034] The second curved segment 21222 extends from bottom to top from the side away from the first sheet-like main body 2111 towards the side closer to the first sheet-like main body 2111, and the second inclined segment 21223 extends from bottom to top from the side closer to the first inclined segment 21122 towards the side away from the first inclined segment 21122.

[0035] like Figure 8 and Figure 9 As shown, in some embodiments, all first springs 2112 have the same dimensions along the length direction of the main colloid 10; and / or, all second springs 2122 have the same dimensions along the length direction of the main colloid 10. In this application, all first springs 2112 have the same dimensions along the length direction of the main colloid 10, and all second springs 2122 have the same dimensions along the length direction of the main colloid 10.

[0036] like Figure 8 and Figure 9 As shown, the first spring 2112 is smaller in size along the length of the main colloid 10 than the second spring 2122 is, and the first spring 2112 and the second spring 2122 are set approximately offset from each other.

[0037] like Figure 8 and Figure 9 As shown, each external power terminal 211 includes three first pins 2113 connected to the lower end of the first sheet-like body 2111, and / or each internal power terminal 212 includes three second pins 2123 connected to the lower end of the second sheet-like body 2121. In this application, each external power terminal 211 includes three first pins 2113 connected to the lower end of the first sheet-like body 2111, and each internal power terminal 212 includes three second pins 2123 connected to the lower end of the second sheet-like body 2121.

[0038] like Figure 3 As shown, the standard-sized, ultra-high power density anti-mating PIN crimp terminal connector also includes several bottom covers 40, which are detachably connected to the main body 10.

[0039] Each bottom cover 40 is provided with a plurality of first through holes 41 and a plurality of second through holes 42. Both the first through holes 41 and the second through holes 42 extend along the length of the bottom cover 40. The second through holes 42 are located inside the first through holes 41. The first through holes 41 are used for the first pin 2113 to pass through, and the second through holes 42 are used for the second pin 2123 to pass through. The number and position of the first through holes 41 and the second through holes 42 can be set according to the number and position of the external power terminals 211 and the internal power terminals 212, and are not specifically limited here.

[0040] like Figure 3 As shown, the bottom cover 40 and the main adhesive body 10 can be detachably connected by a snap-fit ​​connection. For example, the opposite side walls of the main adhesive body 10 can be provided with a plurality of slots 12, which are spaced apart along the length of the main adhesive body 10. The opposite sides of the bottom cover 40 are provided with a plurality of snaps 43, which are spaced apart along the length of the bottom cover 40. The snaps 43 are engaged with the slots 12 for easy assembly. In this application, the main adhesive body 10 can be made of plastic material, and the bottom cover 40 can also be made of plastic material. The material can be selected and set according to actual needs, and no specific limitation is made here.

[0041] like Figure 3 As shown, in some embodiments, the bottom surfaces of both ends of the main colloid 10 along its length are respectively provided with positioning posts 13, the lower ends of which protrude from the lower ends of the first pin 2113 and the second pin 2123 (e.g. Figure 5 As shown, the positioning post 13 can be positioned and inserted into the circuit board.

[0042] like Figure 5 As shown, the inner surfaces of the insertion hole 11 are symmetrically arranged inclined guide surfaces 111. The inclined guide surfaces 111 are inclined from top to bottom toward the center of the insertion hole 11. The upper end of the external power terminal 211 is positioned away from the lowermost end of the inner surface of the insertion hole 11. The width of the lowermost end of the inclined guide surface 111 can be the same as or similar to the width of the gold finger plate 100, which can guide the gold finger plate 100 to be inserted into the clamping space 20a from the insertion hole 11, so that the gold finger plate 100 contacts the power terminal group 20 to achieve electrical connection.

[0043] In some embodiments, the overall length of the plug hole 11 may be 66.04 mm and the width may be 1.8 mm.

[0044] like Figure 3As shown, in some embodiments, each signal terminal group 30 includes two symmetrically arranged signal terminals 31. In this application, the signal terminal group 30 may use existing technology, which will not be described in detail here. In this application, the number of signal terminal groups 30 may be seven, that is, fourteen signal terminals 31.

[0045] In this application, the high power density anti-collision PIN crimp terminal connector of this standard size has a stronger ability to transmit current and can output higher power compared with existing products; it can detect poor spring height or missing spring of the second spring 2122 of the inner power terminal 212; and can avoid PIN failure when mating with the gold finger board 100.
