Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a schematic overall structure diagram of an embodiment of the present invention.

In one embodiment of the present invention, the modular power supply connection mechanism mainly includes several female connectors 3 and a conductive rail, and the conductive rail specifically includes several stages of extension joint modules 4, a first male connector 5 and a second male connector 6.

Each female connector 3 is respectively arranged on the mainboard 1 and the external board card 2, and is respectively connected with the mainboard 1 and the external board card 2 in a signal mode. Generally, the female connectors 3 are respectively disposed on the PCB surface of the main board 1 and the PCB surface of the external board card 2.

The multistage extension joint modules 4 are sequentially connected end to end and are distributed by clinging to the surface of the mainboard 1 and the outer wall of the external board card 2, and extend from the position of the female connector 3 on the mainboard 1 to the position of the female connector 3 on the external board card 2. Generally, the plugging direction of the external board card 2 on the motherboard 1 is generally only vertical and horizontal, so that the multi-stage extension joint module 4 is generally extended to form an L shape, a I shape or an I shape, and of course, the multi-stage bending step shape can also be formed according to the actual installation space.

The first male connector 5 is arranged on the extension joint module 4 at the first stage and is mainly used for forming butt joint matching and signal connection with the female connector 3 on the mainboard 1. The second male connector 6 is arranged on the extending joint module 4 at the final stage and is mainly used for forming butt joint matching and signal connection with the female connector 3 on the external board card 2.

Therefore, the modularized power supply connection mechanism provided by the embodiment, through the butt joint cooperation of the first male connector 5 and the female connector 3 on the motherboard 1, the butt joint cooperation of the second male connector 6 and the female connector 3 on the external board card 2, and the connection of the extension joint modules 4 and the first male connector 5 at all levels and the second male connector 6, can smoothly realize the power supply connection between the motherboard 1 and the external board card 2, and meanwhile, because the extension joint modules 4 at all levels are tightly attached to the surface of the motherboard 1 and the outer wall surface of the external board card 2, the suspension of the extension joint modules 4 in the space between the motherboard 1 and the external board card 2 can be avoided, and further the heat dissipation space between the motherboard 1 and the external board card 2 is avoided, thereby avoiding blocking the heat dissipation air duct and ensuring the heat dissipation effect of the server.

As shown in fig. 2, fig. 2 is a detailed structural schematic diagram of the female connector 3.

In a preferred embodiment with respect to the female connector 3, the female connector 3 mainly comprises a housing 31 and a patch jack 32. The housing 31 is a main body structure of the female connector 3, and is generally rectangular or cylindrical. The plug socket 32 is formed on the housing 31, typically on the top or side surface of the housing 31, and is mainly used for mating with the connection end of the first male connector 5 or the second male connector 6 to realize signal connection.

As shown in fig. 3, fig. 3 is a sectional view of the female connector 3.

In a preferred embodiment of the plug socket 32, in order to improve the connection stability between the plug socket 32 and the first male connector 5 or the second male connector 6 and prevent accidental falling, a plurality of inner spiral grooves 33 are formed on the inner wall surface of the plug socket 32, a plurality of first outer spiral threads 51 are formed on the outer wall surface of the first male connector 5, and a plurality of second outer spiral threads 61 are formed on the outer wall surface of the second male connector 6. Specifically, each of the inner spiral grooves 33 is arranged and distributed on the inner wall surface of the patch hole 32 in the circumferential direction, extends in the axial direction, and forms a spiral shape by forming a certain inclined angle with the axial direction of the patch hole 32.

Similarly, the first outer spiral threads 51 are arranged and distributed along the circumferential direction on the outer wall surface of the connecting end of the first male connector 5, extend along the axial direction, and form a spiral shape by forming a certain inclined included angle with the axial direction of the connecting end. The second external spiral thread 61 is identical to the first external spiral thread 51 and will not be described in detail herein. Thus, when the connection end of the first male connector 5 or the second male connector 6 is inserted into the plug hole 32, the first external spiral thread 51 or the second external spiral thread 61 will form a snap fit with the internal spiral groove 33, so as to improve the connection stability and prevent the connection from being easily released.

Further, in order to further enhance the connection stability of the plug 32 with the first male connector 5 or the second male connector 6, in the embodiment, the plug 32 is embodied as a hyperbolic contracted hole, and the cross-sectional shape thereof is hyperbolic, that is, the plug hole has a large diameter at both ends and a small diameter at the middle. Meanwhile, the plug 32 is embodied as an elastic hole having an elastic expansion and contraction characteristic. With this arrangement, when the connection end of the first male connector 5 or the second male connector 6 is inserted into the plug hole 32, the connection end needs to overcome the elastic force of the plug hole 32 to achieve that the first external spiral thread 51 or the second external spiral thread 61 will form a snap fit with the internal spiral groove 33, and further, the elastic pre-tightening force of the plug hole 32 enhances the degree of tightness of the snap fit between the first external spiral thread 51 or the second external spiral thread 61 and the internal spiral groove 33.

Fig. 4 is a schematic view of the female connector 3 in two orientations, as shown in fig. 4.

Furthermore, considering that the plugging direction of the external board card 2 on the motherboard 1 is generally vertical or horizontal, for this reason, in the present embodiment, the plug jack 32 of the female connector 3 on the motherboard 1 is oriented perpendicular to or parallel to the surface of the motherboard 1, and similarly, the plug jack 32 of the female connector 3 on the external board card 2 is oriented perpendicular to or parallel to the outer wall surface of the external board card 2. Of course, if necessary, the female connector 3 may also be disposed on the motherboard 1 or the external board 2 at a certain inclination angle.

Fig. 5 is a schematic view showing a connection structure of the extension joint module 4, as shown in fig. 5.

In a preferred embodiment with respect to the extension joint module 4, the extension joint module 4 mainly comprises end joints 4a and middle joints 4 b. The end joints 4a are generally arranged at two times and located at the first stage and the last stage of the whole conductive guide rail, the middle joint 4b is the middle part of the whole conductive guide rail, and a plurality of joints are usually arranged when the distance between the main board 1 and the external board card 2 is far away, and only two joints can be arranged when the distance is short. Meanwhile, the outer end of the end joint 4a positioned at the first stage is connected with a first male connector 5, the outer end of the end joint 4a positioned at the last stage is connected with a second male connector 6, the head end and the tail end of each stage of middle joint 4b are sequentially connected, the inner end of the end joint 4a positioned at the first stage is connected with the end part of the adjacent middle joint 4b, and the inner end of the end joint 4a positioned at the last stage is connected with the end part of the adjacent middle joint 4b, so that the whole conductive guide rail chain is formed.

For example, for the situation that the distance between the main board 1 and the external board card 2 is short and the main board is vertically connected, 1 end joint 4a and 1 middle joint 4b can be tightly attached to the surface of the main board 1, and simultaneously, 1 middle joint 4b and 1 end joint 4a are tightly attached to the surface of the outer wall of the external board card 2, and the two middle joints 4b are vertically connected, so that the whole conductive guide rail chain forms an 'L' shape.

As shown in fig. 6 and 7, fig. 6 is a specific structural schematic diagram of the first male connector 5 or the second male connector 6, and fig. 7 is a specific structural schematic diagram of the connection tenon 7.

Further, considering that the specific arrangement direction of the female connector 3 on the motherboard 1 and the external board card 2 may be different, in order to facilitate the respective adjustment orientations of the first male connector 5 and the second male connector 6 to be smoothly connected with the female connector 3, in this embodiment, the first male connector 5 and the second male connector 6 are respectively connected with the outer ends of the corresponding end joints 4a in a rotating manner through the connecting tenon 7.

Specifically, the connecting tenon 7 is an optical axis structure, a U-shaped groove can be formed in the end joint 4a to facilitate the insertion of the connecting tenon 7, and meanwhile, the first male connector 5 and the second male connector 6 can be provided with rotating holes to facilitate the sleeving of the connecting tenon 7. With this arrangement, the first male connector 5 can be rotated on the first end knuckle 4a, and the second male connector 6 can be rotated on the last end knuckle 4a, so as to adjust the respective mating angles. Generally, the rotation angle ranges of the first male connector 5 and the second male connector 6 are both 0-180 °, and the rotation axes of the first male connector and the second male connector are perpendicular to each other. Of course, the connecting tenon 7 can be replaced by a pin or the like.

As shown in fig. 8 and 9, fig. 8 is a detailed structural view of the end joint 4a, and fig. 9 is a detailed structural view of the middle joint 4 b.

Furthermore, in view of the possibility of a reversal of the conductive track in the middle of its extension, such as a vertical reversal, in the present embodiment, the two adjacent intermediate joints 4b are each connected in a rotatable manner by a connecting tongue 7. So arranged, the ends of two adjacent middle joints 4b can perform circumferential rotation motion around the connecting tenon 7. Generally, the rotation angle range of two adjacent middle joints 4b is 0 to 360 °.

Furthermore, in order to further improve the freedom of movement of the conductive rail, in this embodiment, the inner end of the end joint 4a is rotatably connected to the adjacent middle joint 4b via a rotating shaft 8. Specifically, the rotation shaft 8 is disposed at the center of the inner end surface of the end joint 4a, and the end surface of the adjacent middle joint 4b may be disposed with a rotation groove into which the rotation shaft 8 is fitted. With this arrangement, the two end joints 4a can perform circumferential rotation motion around the axial direction thereof. In general, the rotation angle of the end joint 4a is in the range of 0 to 360 °.

The embodiment further provides a server, which mainly includes a motherboard 1, an external board card 2, and a modular power supply connection mechanism connected therebetween, wherein specific contents of the modular power supply connection mechanism are the same as those of the above-mentioned related contents, and are not described herein again.

The previous description of the disclosed embodiments is provided to enable any person 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 generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
