Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and more particularly to a floating and waterproof connector assembly. Background Art

[0002] Fan connectors are commonly used components in mainframes. Their function is to aggregate the wiring harnesses of various fans into a single unit, which then connects to the mainframe. Existing fan connectors suffer from poor positioning accuracy during mating, resulting in problems with mating. Furthermore, most of these connectors lack waterproofing, which often shortens their service life.

[0003] In actual applications, since the user's spatial position may be left or right, it is necessary to develop left- or right-facing connectors, with many models, which increases costs.

[0004] In practical applications, modules can be assembled in both forward and reverse directions. To meet these requirements, a rotatable structure is often used. However, this rotatable structure is expensive and complex. Summary of the Invention

[0005] The object of the present invention is to provide a floating, waterproof connector assembly to solve the problems existing in the above-mentioned background technology.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A floating, waterproof connector assembly includes a connector socket and a connector plug harness. The connector socket is connected to a welding plate connector in a host. The connector plug harness is installed on the host via floating screws. The connector plug harness is plugged and sealed to the connector socket.

[0008] Furthermore, the connector socket includes a first insulator, a printed circuit board and a fixing colloid sealing ring. The first insulator is provided with a mounting cavity with both ends open, and the printed circuit board is fixed in the mounting cavity, wherein one end of the printed circuit board is arranged in the mounting cavity of the first insulator, and the other end of the printed circuit board is arranged outside the mounting cavity of the first insulator. The fixing colloid sealing ring is used to bond the connection between the insulator and the printed circuit board and realize the sealing of the interior of the mounting cavity; the first insulator is provided with a mounting surface on the side of the printed circuit board arranged outside the mounting cavity, and a sealing gasket is provided on the mounting surface.

[0009] Furthermore, the mounting cavity of the first insulator is linear or curved, and the angle between the two ends of the printed circuit board fixed inside the linear mounting cavity is 180°, while the angle between the two ends of the printed circuit board fixed inside the curved mounting cavity is greater than 0° and less than 180°.

[0010] Furthermore, both ends of the printed circuit board are gold finger structures that are evenly and symmetrically arranged up and down, one end of the installation cavity is the inner plug-in end, and the other end of the installation cavity is the outer plug-in end, and the printed circuit board is centrally symmetrical with the inner plug-in end and the outer plug-in end.

[0011] Furthermore, the connector plug harness includes a second insulator, a sealing ring, a floating screw, a plastic package, a terminal, and a cable. The terminal is fixed in the second insulator, and one end of the terminal is used to cooperate with the pin of the plug connector, and the other end of the terminal is connected to the cable. The sealing ring is sleeved on the outer diameter of the second insulator, and the plastic package wraps the terminal, cable and the second insulator.

[0012] Furthermore, the plastic package body is provided with a mounting end at one end close to the second insulator, and guide columns for matching with the jacks of the mating connector are respectively provided on the mounting ends on the upper and lower sides of the second insulator.

[0013] Furthermore, a tapered guide surface is provided at the front end of the guide column.

[0014] Furthermore, the outer contour of the second insulator and the guide posts provided on the upper and lower mounting ends of the second insulator all adopt a centrally symmetrical structure, and the terminals are evenly and symmetrically arranged in the upper and lower parts.

[0015] Furthermore, the first insulator is provided with guide holes on the upper and lower sides of the outer wall of one side of the printed circuit board arranged in the installation cavity, for fixing the guide posts on the connector plug harness.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The present invention has a novel structure and strong practicality. The connector harness assembly of the present invention is easy to operate, floats, and achieves full waterproofing and other functions after plugging and connecting. It has a simple structure, low cost, and significantly improves labor efficiency during use. The present invention solves the problem of poor positioning accuracy of the module during the plug-in process, resulting in mismatching. Due to the provision of floating screws and guide posts, the positioning accuracy requirements for the entire module are relatively low.

[0018] 2. The present invention has a novel structure and strong practicality. The first insulator of the connector socket of the present invention can be divided into two types: straight and curved. The connector uses a printed circuit board as a connector to mate with other units. It has floating, waterproof, and 180° double-sided mating functions.

[0019] 3. The printed circuit board of the present invention particularly innovatively adopts a double-headed gold finger structure, especially a curved structure, which effectively simplifies the overall product structure and is relatively low in cost. In addition, a variety of electrical components can be integrated on the printed circuit board to achieve multi-functional configuration.

[0020] 4. According to the user's spatial position, the curved type can be selectively placed to the left or right, without the need to redevelop this type of connector, which is more versatile. The connector has a guide hole structure on the socket part, which can cooperate with the plug end to achieve a floating function.

[0021] 5. During the connector insertion process of the present invention, radial waterproof sealing is achieved through the sealing ring and the butt-end connector, and the plastic sealing body wraps the terminal, cable and second insulator to form a seal.

[0022] 6. During the mating process of the connector socket and plug, an electrical connection is achieved through the printed circuit board and the mating connector, and then the floating screw is installed to form a waterproof seal between the sealing gasket and the box. This function solves the problem that conventional connectors cannot be used in outdoor environments, fills the industry gap, and increases the service life of the product.

DETAILED DESCRIPTION

[0038] The present invention will be further described below with reference to the embodiments. The embodiments described are only a part of the embodiments of the present invention and are not all embodiments. Based on the embodiments of the present invention, other embodiments obtained by ordinary technicians in this field without making creative work are all within the scope of protection of the present invention.

[0039] Embodiment 1:

[0040] like Figure 1-6 The figure shows a floating, waterproof connector assembly, including a connector socket 2 and a connector plug harness 3. The connector socket 2 is fixed to the mainframe housing, and a welding board connector 1 is installed inside the mainframe. During installation, the connector socket 2 is connected to the welding board connector 1 in a plug-in manner. The connector plug harness 3 is mounted on the mainframe using floating screws 5, and the connector plug harness and connector socket 2 are connected in a plug-in and sealed manner.

[0041] In this embodiment, the connector socket 2 includes a first insulator, a printed circuit board 13, and a fixing colloid sealing ring 4. The first insulator is provided with a mounting cavity with both ends open, and the printed circuit board 13 is fixed in the mounting cavity. One end of the printed circuit board 13 is disposed within the mounting cavity of the first insulator, and the other end of the printed circuit board 13 is disposed outside the mounting cavity of the first insulator. The fixing colloid sealing ring 4 is used to bond the connection between the first insulator and the printed circuit board 13 and to achieve sealing within the mounting cavity. The first insulator is provided with a mounting surface 14 on the side of the printed circuit board 13 disposed outside the mounting cavity, and a sealing gasket 19 is provided on the mounting surface 14.

[0042] Both ends of the printed circuit board 13 feature gold finger structures that are evenly and symmetrically arranged vertically. One end of the mounting cavity is the inner plug-in end, and the other end is the outer plug-in end 18. The printed circuit board 13 is centrally symmetrical with the inner and outer plug-in ends 18. The outer plug-in end 18 of the connector receptacle 2 of this embodiment is inserted into the mounting opening of the main chassis, enabling a direct plug-in connection between the printed circuit board 13 and the solder board connector 1 within the chassis. A sealing gasket contacts the main chassis panel to achieve a waterproof seal. The inner plug-in end is connected to the plug connector.

[0043] The printed circuit board 13 of this embodiment particularly innovatively adopts a double-headed gold finger structure, especially a bent structure, which effectively simplifies the overall product structure and is relatively low in cost. In addition, a variety of electrical components can be integrated on the printed circuit board 13 to achieve a multifunctional configuration.

[0044] In this embodiment, the mounting cavity of the first insulator is linear. Figure 9-11 As shown, or bent, as Figure 12-14 As shown, the included angle between the two ends of the printed circuit board 13 fixed in the linear mounting cavity is 180°, while the included angle between the two ends of the printed circuit board 13 fixed in the curved mounting cavity is greater than 0° and less than 180°. Preferably, it is 90°. The included angle between the two ends of the printed circuit board 13 in the mounting cavity is 90°, which facilitates processing and manufacturing.

[0045] The insulator of the connector socket 2 of this embodiment can be divided into two types: straight and curved, and a plug connector. The connector uses a printed circuit board 13 as a connector to mate with other units and has floating, waterproof, and 180° double-sided mating functions.

[0046] According to the user's spatial position, the curved type can be selectively placed to the left or right, without having to redevelop this type of connector, which is more versatile. The connector has a guide hole 15 structure on the socket part, which can cooperate with the plug end to achieve a floating function.

[0047] like Figure 7-8 As shown, in this embodiment, the connector plug harness 3 includes a second insulator, a sealing ring 6, a floating screw 5, a plastic package 8, a terminal 11, and a cable 7. The terminal 11 is fixed in the second insulator, and one end of the terminal 11 is used to cooperate with the pin of the plug connector, and the other end of the terminal 11 is connected to the cable 7. The sealing ring 6 is sleeved on the outer diameter of the second insulator, and the plastic package 8 wraps the terminal 11, the cable and the second insulator.

[0048] In this embodiment, the outer contour of the second insulator and the guide posts 10 provided on the upper and lower mounting ends 12 of the second insulator all adopt a centrosymmetrical structure, and the terminals 11 are evenly and symmetrically arranged up and down.

[0049] During the insertion process with the inner plug-in end of the connector socket 2, a radial waterproof seal is achieved through the sealing ring 6 on the outer contour of the second insulator and the inner plug-in end, and the plastic package 8 wraps the terminal 11, the cable and the second insulator to form a seal.

[0050] In this embodiment, the plastic encapsulation body 8 has a mounting end 12 at one end near the second insulator. Guide posts 10 are provided on the upper and lower sides of the mounting end 12 of the second insulator, respectively, for mating with the receptacles of the mating connector. Floating screws 5 are also provided on the upper and lower sides of the mounting end 12 of the second insulator. Guide holes 15 are provided on the upper and lower sides of the outer wall of the first insulator on the side where the printed circuit board 13 is positioned within the mounting cavity, for securing the guide posts 10 on the connector plug harness 3.

[0051] Specifically, floating screws 5 are installed at the upper left and lower right corners, or the upper right and lower left corners, of the mounting end 12. The connector harness assembly is mounted on the module as a whole via the floating screws 5, and the insulator is provided with a guide post 10 structure, thereby achieving floating and guided assembly during the plug-in process.

[0052] More preferably, the front end of the guide column 10 is provided with a tapered guide surface, which can make the connector harness assembly more convenient when plugging and connecting with the connector at the plug end.

[0053] The insulator has a mounting surface 14 on the side of the printed circuit board 13 located outside the mounting cavity, and a sealing gasket is provided on this mounting surface. During mating between the connector receptacle 2 and the plug, an electrical connection is established between the printed circuit board 13 and the mating connector. The floating screw 5 is then installed to create a waterproof seal between the sealing gasket and the housing. This feature addresses the problem of conventional connectors being unsuitable for outdoor use, filling an industry gap and extending the product's service life.

[0054] The insulator has guide holes 15 on the upper and lower sides of the outer wall of the printed circuit board 13 on the side of the mounting cavity, which are used to fix the guide posts 10 on the plug connector. During the plugging process, the guide holes 15 structure cooperates with the guide posts 10 of the plug connector to achieve a floating function.

[0055] Preferably, a floating screw 5 is provided on the mounting surface 14; the floating function solves the problem of the module not being able to be plugged in due to poor positioning accuracy during the plugging process, and has a low positioning accuracy requirement for the entire module.

[0056] Preferably, a plurality of reinforcing ribs are provided between the guide hole 15 and the mounting surface 14 to improve the overall stability.

[0057] In actual applications, connectors can be assembled in both forward and reverse directions. In order to meet the needs, a rotatable structure is often used. The innovative design of this connector is a centrally symmetrical structure, which not only meets the functional needs but also has a very simple structure and low cost, solving the industry's pain points.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
