Description

Technical Field

[0001] This utility model relates to a connector assembly that can be floated in multiple directions, belonging to the field of electronic device connector technology. Background Technology

[0002] As electronic devices evolve towards higher density and miniaturization, connectors, as core components for signal and power transmission between devices, become particularly important in terms of their installation methods and structural performance. In practical applications, to address issues such as installation errors, thermal expansion, and structural deviations, connectors with floating installation methods are often used. This allows the connector to move relative to other devices within a certain range, thereby improving the stability and reliability of the mating connection.

[0003] In existing technologies, floating connectors typically employ a pre-existing gap in the axial or radial direction, along with elastic elements for limiting, to achieve unidirectional floating adjustment. While this type of structure can alleviate assembly difficulties caused by deviations during connection to some extent, its floating direction is limited, and it cannot simultaneously accommodate multi-directional compensation in both axial and radial directions. Especially in high-density wiring or complex structural environments, this can easily lead to problems such as poor connection and abnormal component stress.

[0004] To meet the need for multi-directional floating, some structures attempt to achieve multi-directional floating of the connector through multiple mating structures or complex sliding mechanisms. However, these structures generally have drawbacks such as large size, many parts, and high processing and assembly difficulty, making them difficult to adapt to high-density installation spaces and ensuring reliability. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and solve the problem that existing floating connectors can only float in one of the axial or radial directions, while connectors with multi-directional displacement have complex structures and are not suitable for high-density installation.

[0006] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0007] A connector assembly capable of multidirectional floating mounting is provided, including a first connector, a second connector mating with the first connector, and a first mounting plate for mounting the first connector;

[0008] The first mounting plate is provided with a first through hole and a second through hole, and the fixed end of the first connector includes a flange forming a threaded hole; the mating end of the first connector passes through the second through hole along a first direction.

[0009] The connector assembly also includes a screw, an internally hollow sleeve, and a limiting spring. The limiting spring is sleeved on the outside of the sleeve. The screw includes a head and a shank. The screw passes through the sleeve in a second direction opposite to the first direction. The head of the screw is located inside the sleeve. The shank of the screw passes through the sleeve and the limiting spring and is threaded into the threaded hole of the flange.

[0010] There is a first radial gap between the outer wall of the first connector and the inner wall of the second through hole, a second radial gap between the outer wall of the sleeve and the inner wall of the second through hole, and an axial distance between the sleeve and the first mounting plate.

[0011] Furthermore, the fixed end and the mating end of the first connector are located on both sides of the first mounting plate, respectively.

[0012] Furthermore, when the first connector and the second connector are not mated, the limiting spring is in a compressed state or a free state and has a first length; when the first connector and the second connector are mated, the limiting spring is in a compressed state and has a second length, wherein the first length is greater than or equal to the second length.

[0013] And / or, when the first connector and the second connector are not mated, the flange abuts against the first mounting plate, and the distance between the flange and the first mounting plate is 0; when the first connector and the second connector are mated, the distance between the flange and the first mounting plate is greater than or equal to 0.

[0014] Furthermore, the sleeve includes a first mounting portion and a second mounting portion. The first mounting portion has an internal cavity for accommodating the screw head. The second mounting portion is fitted with a limiting spring to provide elastic compression space during screw tightening.

[0015] Furthermore, the first through hole has a first inner wall, a second inner wall and a third inner wall in sequence along the first direction, wherein the inner diameter of the first inner wall is smaller than the inner diameter of the second inner wall and the inner diameter of the second inner wall is smaller than the inner diameter of the third inner wall.

[0016] in:

[0017] The first inner wall is used to accommodate the first mounting part;

[0018] The second inner wall is used to restrict the displacement of the first mounting part in the axial direction;

[0019] The third inner wall is used to limit the installation of the limiting spring.

[0020] Furthermore, a second radial gap exists between the first mounting portion and the first inner wall;

[0021] There is a third radial gap between the limiting spring and the second inner wall;

[0022] There is a fourth radial clearance between the screw and the third inner wall;

[0023] There is an axial gap between the first mounting part and the second inner wall in a first direction.

[0024] Furthermore, the second connector includes a plug portion and a second mounting plate. The plug portion is provided with a female port and a guide post located at its edge. The surface of the second mounting plate is provided with a first mounting groove for plugging into the plug portion.

[0025] Furthermore, the end of the first connector away from the flange is provided with a male port that mates with the female port; the male port is provided with a blind hole in the insertion direction for mating with the guide post.

[0026] Furthermore, a third through hole is provided in the middle of the first mounting part, and a slot for fixing screws is provided between the first mounting part and the second mounting part. The third through hole is used to insert screws.

[0027] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0028] This invention enables the first connector to achieve axial and radial floating adjustment during installation by setting a first radial gap between the outer wall of the first connector and the second through hole, setting a second radial gap between the outer wall of the sleeve and the second through hole, and setting an axial distance between the sleeve and the first mounting plate. When the mating position is not completely aligned due to assembly deviation, structural deformation, or thermal expansion and contraction during connector insertion, the limiting spring can be compressed under the traction of the screw, and the sleeve will then generate axial displacement relative to the first mounting plate, thereby driving the first connector to automatically adjust to adapt to the insertion position of the second connector, effectively improving the connection alignment accuracy and insertion smoothness. At the same time, the radial gap structure gives the first connector a certain lateral floating ability, enhancing its adaptability to external interference without increasing structural complexity, and avoiding problems such as insertion obstruction or uneven connection force caused by rigid connection.

[0040] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0041] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0042] like Figure 1 As shown, a connector assembly capable of multidirectional floating installation is provided, including a first connector 1 and a second connector 2 mating with the first connector 1. One end of the first connector 1 includes a flange 11 forming a threaded hole 111; a first mounting plate 3 is mounted on the first connector 1 via the flange 11.

[0043] like Figure 1 As shown, Figure 1 The black arrow in the middle indicates the first direction, and then the mating end of the first connector 1 passes through the second through hole 32; subsequently, the screw 4 passes through the sleeve 5 in a second direction opposite to the first direction.

[0044] like Figure 1 , Figure 4 and Figure 5 As shown, the screw 4 is installed in the first through hole 31 through the sleeve 5. The sleeve 5 includes a first mounting part 51 and a second mounting part 52. The outer wall of the second mounting part 52 is fitted with a limiting spring 6, which is limited in the first through hole 31 by the first mounting part 51.

[0045] like Figure 6 As shown, the surface of the first mounting plate 3 is provided with a first through hole 31 for mounting a screw 4, and the screw 4 passes through the first through hole 31 and connects to the threaded hole 111; the first mounting plate 3 also includes a second through hole 32 for engaging with the first connector 1, and a first radial gap 1d is provided between the second through hole 32 and the first connector 1.

[0046] The first through hole 31 has a first inner wall, a second inner wall, and a third inner wall. The first inner wall and the second inner wall have a difference in their inner diameters, which forms a sleeve limiting groove 311 for accommodating the sleeve. Similarly, the second inner wall and the third inner wall form a spring limiting groove 312 for limiting the spring. The spring limiting groove 312 and the first mounting part 51 form a travel space for the deformation of the limiting spring 6. An axial gap 2a is provided between the first mounting part 51 and the sleeve limiting groove 311. The first connector 1 achieves axial floating relative to the first mounting plate 3 through the axial gap 2a.

[0047] like Figure 1 As shown, a radial gap is provided between the sleeve 5 and the inner wall of the first through hole 31.

[0048] Specifically, the radial clearance includes a second radial clearance 1a, a third radial clearance 1b, and a fourth radial clearance 1c; the distance between the first mounting part 51 and the inner wall of the first through hole 31 is the second radial clearance 1a, the radial distance between the inner wall of the spring and the sleeve limiting groove 311 is the third radial clearance 1b, and the radial distance between the inner wall of the screw 4 and the inner wall of the spring limiting groove 312 is the fourth radial clearance 1c.

[0049] like Figure 8 and Figure 9 As shown, the second connector 2 includes a plug-in portion 21 and a second mounting plate 22; the plug-in portion 21 is provided with a female port 211 and a guide post 212 provided on the side of the mating port; the surface of the second mounting plate 22 is provided with a first mounting groove 221 for plugging into the plug-in portion 21.

[0050] like Figure 1 , Figure 3 and Figure 8 As shown, the first connector 1 has a male port 12 on one end face away from the flange 11 that mates with the female port 211, and the male port 12 has a blind hole 13 in the direction of which it is inserted into the guide post 212.

[0051] like Figure 4 As shown, the first mounting part 51 has a third through hole 53 in the middle, and a slot 54 for fixing the screw 4 is provided between the first mounting part 51 and the second mounting part 52. The third through hole 53 is used to insert the screw 4.

[0052] like Figure 7 As shown, the screw 4 includes a head 41 and a screw 42; the screw 4 is fixed to the slot 54 by the head 41.

[0053] The specific workflow is as follows: place the screw 4 in the slot 54, place the limiting spring 6 in the spring limiting groove 312 of the first mounting plate 3, place the sleeve 5 in the sleeve limiting groove 311 of the first mounting plate 3, and put the limiting spring 6 on the second mounting part 52; the first connector 1 passes through the second through hole 32 on the surface of the first mounting plate 3, and fastens the mounting screw 4 through the threaded hole 111 on the flange 11.

[0054] When the first connector 1 and the second connector 2 are mated, the guide post 212 on the surface of the insertion part 21 first aligns with the blind hole 13 on the surface of the first connector 1. Through the radial mounting gaps of the first connector 1—namely, the second radial gap 1a, the third radial gap 1b, the fourth radial gap 1c, and the first radial gap 1d—radial floating of the first connector 1 relative to the first mounting plate 3 is achieved. During subsequent mating, when the second connector 2 applies pressure to the first connector 1 through its mating end, the pressure drives the screw 4 via the flange 11 to generate a downward pull on the sleeve 5. The sleeve 5 transmits this downward pull to the limiting spring 6. The lower surface of the limiting spring 6 is limited by the first mounting plate 3. When the downward pull exceeds the spring's deformation force, the limiting spring 6 compresses and deforms, reducing the distance between the sleeve 5 and the first mounting plate 3. At this point, the first connector 1 and the screw 4 move downward together. When the pressure disappears, the holding force of the limiting spring 6 decreases, the limiting spring 6 extends, the distance between the sleeve 5 and the first mounting plate 3 increases, and the first connector 1 returns to its initial position, achieving axial floating of the first connector 1. This achieves multi-directional floating installation.

[0055] It should be mentioned that when the first connector 1 and the second connector 2 are in a mating state and their positions are well matched, that is, the axial position of the connector is accurate and no adjustment is needed, the flange (11) of the first connector 1 is not pushed, and the spring is not subjected to additional compression. At this time, the spring maintains its original state, and its length is the first length. At this time, the first length is equal to the second length, indicating that axial floating compensation is not triggered during the mating process.

[0056] When the first connector 1 and the second connector 2 are in a mating state and there is an axial positional deviation, the second connector 2 applies pressure to the first connector 1 along the second direction. Since the first mounting plate 3 is fixedly installed in the equipment and cannot be moved, the pressure is transmitted to the flange 11, pushing the screw 4, sleeve 5 and the connected first connector 1 as a whole to move relative to the first mounting plate 3 along the second direction. During this process, the limiting spring 6 is compressed, forming a deformation, and its length changes from a first length to a second length, where the first length is greater than the second length. This process realizes automatic compensation for axial positional errors, which helps to improve the reliability and durability of connector mating.

[0057] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
