In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.
[0028] The embodiment of the utility model provides an adapter plate 4 and a connector assembly to solve the problem that the cable connection method occupies a large space and has poor heat dissipation.
[0029] like Figure 1 As shown, the connector assembly includes a bracket 1 and a first board 2 and a second board 3 arranged on the bracket 1, wherein the first board 2 is a main board, and the second board 3 is a service board. For example, Figure 1There are three service boards shown, and multiple service boards are connected to the mainboard, and multiple service boards can be replaced at will to realize different service functions. In the prior art, the first board 2 and the second board 3 are mostly connected by cables, resulting in large occupied space and poor heat dissipation.
[0030] In order to solve this technical problem, the utility model provides a transfer plate 4, such as Figure 2 The adapter board 4 is used for connecting the first board 2 and the second board 3, wherein the first board 2 is provided with a first connector 21, and the second board 3 is provided with a second connector 31. The adapter board 4 is arranged between the first connector 21 and the second connector 31, and is used for plug-in connection between the first connector 21 and the second connector 31, so as to realize the plug-in connection between the first board 2 and the second board 3.
[0031] like Figure 3-Figure 5 The adapter board 4 includes a main body 41, and a row of gold fingers 42 are respectively provided on both sides along the width direction (Y direction) of the main body 41. Positioning parts 43 are respectively provided at both ends of each row of gold fingers 42. The two rows of gold fingers 42 can be respectively inserted into the slots of the two connectors, and the positioning parts 43 can abut the inner wall of the slot.
[0032] The adapter plate 4 provided by the utility model can realize the plug-in connection of two connectors (the first connector 21 and the second connector 31). The plug-in connection method does not require male and female heads, which is conducive to reducing costs and can be used in scenarios with compact design space. Because the small space occupancy is more conducive to air cooling and heat dissipation; the plug-in connection method can realize the panel connection of multiple PCB boards, which is convenient for forming a modular PCB design solution.
[0033] In some embodiments, the gold fingers 42 are disposed on two sides of the same side of the body 41 , and the positioning portions 43 are disposed at two ends of the gold fingers 42 along the length direction (X direction) of the body 41 .
[0034] like Figure 3 and Figure 5, on the two sides of the body 41 in the thickness direction (Z direction), one of the sides along the width direction is provided with a gold finger 42 respectively, and the gold finger 42 adopts a single-sided design, which can ensure the thickness requirement of the adapter plate 4. When the overall thickness of the adapter plate 4 is 1mm, the thickness tolerance meets the requirement of 0.05mm. Compared with the cable connection method, the connection method using the adapter plate 4 occupies less space and is more suitable for compact products. At the same time, it will not block the airflow duct and is conducive to heat dissipation. In some embodiments, for the FI-RE high-speed signal connector, each row of gold fingers 42 in the adapter plate 4 used includes 51 gold fingers 42, and the spacing between two gold fingers 42 (the distance between the center lines of the two gold fingers 42 along the X direction) D1 is 0.5mm, with a tolerance of ±0.03mm, and the width D2 of a single gold finger 42 is 0.3mm, with a tolerance of ±0.02mm. When the adapter board 4 is inserted into a slot of any connector, the two positioning portions 43 respectively abut against two opposite inner walls of the slot (along the X direction), which is beneficial for the reliable contact of the gold fingers 42 .
[0035] In some embodiments, two groups of positioning portions 43 are provided, and the two groups of positioning portions 43 are respectively arranged at both ends of the length direction of the main body 41. Each group of positioning portions 43 includes two positioning portions 43, and the two positioning portions 43 are respectively arranged on both sides of the width direction of the main body 41. The positioning portions 43 extend from the main body 41 toward a direction away from the main body 41.
[0036] like Figure 3 and Figure 4 As shown, for example, the distance L2 between the opposite outer walls of the two positioning parts 43 is 32.5mm, the length L1 of each row of gold fingers 42 is 25mm, and the tolerance is ±0.05mm. By setting the positioning parts 43, the double positioning of the gold fingers 42 can be achieved, which is conducive to improving the processing accuracy and ensuring the stability during the insertion connection. Among them, the positioning part 43 has an extension setting in the direction away from the body 41, so that when the adapter plate 4 is inserted into the slot, the positioning part 43 can be inserted into the slot first for guidance, which is conducive to improving the plug-in efficiency and reducing the wear of the gold fingers 42.
[0037] In some embodiments, a side of the positioning portion 43 facing away from the gold finger 42 has a straight abutment portion.
[0038] like Figure 4 The outer wall of the positioning portion 43 facing away from the gold finger 42 has a straight section. When the adapter board 4 is inserted into the slot, the straight section abuts against the slot wall of the slot. The design of the straight section is conducive to increasing the contact area between the positioning portion 43 and the slot wall. After installation, the gold finger 42 will not offset and overlap, thereby improving the positioning stability and reliability after insertion, thereby ensuring a stable and complete signal.
[0039] In some embodiments, the end of the positioning portion 43 has an arc transition curved edge.
[0040] like Figure 4 and Figure 5 The end of the positioning portion 43 is the end of the positioning portion 43 away from the body 41. The structure of the arc transition curve edge is conducive to the guided insertion of the positioning portion 43 and the notch of the slot, reducing friction and wear during plug-in contact, and has good guiding performance.
[0041] In some embodiments, the two positioning portions 43 located at both ends of the gold finger 42 have inner sidewalls whose spacing increases gradually in a direction from the main body 41 toward away from the main body 41 .
[0042] like Figure 5 As shown, along the X direction, the inner wall of the positioning portion 43 facing the gold finger 42 is inclined toward the side away from the gold finger 42 and the body 41, so that the distance between the inner walls of the two positioning portions 43 on the same side gradually increases, which is firstly beneficial to the processing of the gold finger 42, and secondly beneficial to reducing the overall structural size of the positioning portion 43 and reducing the material cost.
[0043] In some embodiments, the connection between the inner wall of the positioning portion 43 and the body 41 is configured as an arc transition connection.
[0044] like Figure 5 The inner wall of the positioning portion 43 is connected to the main body 41 by an arc transition. Preferably, the positioning portion 43 and the main body 41 are an integral structural member. The arc transition structure is conducive to molding and stress transition between the positioning portion 43 and the main body 41 to avoid damage caused by excessive force.
[0045] In some embodiments, limiting portions 44 of the protruding positioning portion 43 are provided at both ends along the length direction of the body 41 , and the limiting portions 44 can abut against the notch of the slot.
[0046] like Figure 3 and Figure 4 The limit parts 44 are arranged at both ends of the main body 41 along the length direction X. When the two sides of the width direction Y of the adapter board 4 are respectively inserted into the slots of the two connectors, the two limit parts 44 at both ends can stop at the notch to avoid damage caused by excessive insertion of one side of the adapter board 4. Figure 1 As shown, when the two connectors are plugged in and connected, the distance between the notches of the slots of the two connectors is the width (dimension in the Y direction) of the limiting portion 44 .
[0047] The utility model also provides a connector assembly, such as Figure 1 and Figure 2As shown, the connector assembly includes a first board card 2 and a second board card 3. The first board card 2 and the second board card 3 are respectively provided with a connector, and the two connectors are connected through the adapter board 4 provided by the utility model.
[0048] In this embodiment, three second boards 3 are plug-connected to the first board 2. The first board 2 has a plurality of first connectors 21, and the second board 3 has two second connectors 31. Both the first connector 21 and the second connector 31 are horizontal connectors. Each second board 3 is connected to the first board 2 through two second connectors 31 and two adapter boards 4, so as to realize a modular connector assembly. The plug-in connection mode of the second board 3 makes connection and replacement more convenient. The adapter board 4 is a thin plate, which occupies a small space and is suitable for compact products. At the same time, the adapter board 4 does not block the airflow channel, which is conducive to heat dissipation. The positioning portion 43 provided on the adapter board 4 is similar to a bull horn structure, has a guiding installation function, is conducive to the connection of the adapter board 4 with high dimensional accuracy, and is conducive to improving the signal stability and integrity between the first connector 21 and the second connector 31 or the first board 2 and the second board 3 after the adapter board 4 is connected.
[0049] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
