Description

Technical Field

[0001] The present application relates to the technical field of communication equipment, and in particular to a connector floating installation structure and communication equipment. Background Art

[0002] To ensure connection reliability and shielding effect, and stress-free soldering feet, special connectors used in communication equipment need to be locked with both the PCB board and the housing by fastening screws before the connector soldering feet can be soldered to the PCB board. However, when soldering with the housing, the side of the housing takes up space, affecting operation and transportation, and making welding production difficult.

[0003] If the connector pins are first soldered to the PCB board, and then the PCB board and the housing are locked by fastening screws, and the connector and the housing are locked by fastening screws, the alignment accuracy of the connector and the housing is poor. Forcibly aligning the fastening screws will cause the connector to pull the PCB board, generating a force component to shear the solder pins on the connector, making it difficult to ensure that the solder pins are stress-free. Increasing the requirements for parts and assembly accuracy will significantly increase production costs.

[0004] Therefore, it is necessary to study and improve the above structure and provide a connector floating installation structure and communication equipment in order to achieve a more practical purpose. Summary of the Invention

[0014] In the first aspect, in some embodiments, the slot has a first side wall facing the interior of the shell, and a second side wall opposite to the first side wall, and when viewed along the direction in which the connector extends out of the mounting hole, the first side wall exceeds the second side wall.

[0015] In a first aspect, in some embodiments, one end of the connector is provided with a solder foot that is welded and fixed to the printed circuit board, and ear plates located on both sides of the solder foot and connected to the printed circuit board via fasteners.

[0035] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0036] During connector installation, the connector must first be connected to the housing, and all subsequent processes require the housing to be kept in place, making processing difficult. Specifically, during the production process, the first step is to screw the connector to the housing to ensure effective shielding; the second step is to screw the connector to the PCB; and the third step is to ensure that the solder pins are not subjected to stress while soldering with the entire housing. After soldering is completed, when installing other structural parts and components, the housing must be transported and handled together, which can easily cause deformation and damage to the PCB.

[0037] Because the connector needs to be connected to the housing and PCB board at the same time, it is necessary to ensure that the surface roughness, flatness and verticality of the two connecting surfaces of the connector have extremely high precision to ensure effective overlap and shielding function. Excessive precision will lead to extremely high processing costs.

[0038] In response to the above-mentioned deficiencies or one of the deficiencies, the embodiments of the present application provide a connector floating installation structure and communication equipment to solve the problems of difficult connector production and installation and high installation precision requirements, which can reduce the processing precision of individual parts while ensuring the installation reliability and shielding effect.

[0039] See also Figures 1 to 6 As shown, the first aspect of the embodiment of the present application provides a connector floating installation structure, including:

[0040] The housing 1 is provided with a cavity 11 and a mounting hole 12 communicating with the cavity 11;

[0041] An electronic assembly comprising a printed circuit board 2 mounted in a cavity 11, and a connector 3 mounted on the printed circuit board 2 and having one end extending out of a mounting hole 12;

[0042] The floating plate 4 is sleeved on the connector 3 and has clearance fit with the mounting hole 12 . The gap between the floating plate 4 and the mounting hole 12 is connected by a filling colloid.

[0043] The connector 3 of the connector floating mounting structure of the embodiment of the present application is provided with a floating plate 4. After the connector 3 is fixedly mounted on the printed circuit board 2, due to the clearance fit between the floating plate 4 and the mounting hole 12, the position of the floating plate 4 in the mounting hole 12 can be adjusted within the range allowed by the clearance, thereby facilitating the alignment of the printed circuit board 2 with the mounting position on the housing 1 for fastening and installation, and reducing the accuracy requirements for the alignment. Finally, a colloid is filled in the clearance to bond the floating plate 4 and the housing 1 into a whole, thereby ensuring the reliability and shielding effect of the mounting structure.

[0044] It should be noted that the embodiment of the present application connects the shell 1 by adding a floating plate 4 to replace the structure in which the connector 3 and the shell 1 are directly fastened with fastening screws. The floating plate 4 and the shell 1 are clearance-matched, and the clearance can effectively reduce the verticality and flatness accuracy requirements of the two mounting surfaces on the connector 3; the floating plate 4 can be installed when the shell 1 is installed after the connector 3 and the printed circuit board 2 are welded, which can effectively solve the problem of difficult installation process.

[0045] Among them, the two mounting surfaces on the connector 3 are the horizontal mounting surface for the connector 3 to cooperate with the printed circuit board 2, and the vertical mounting surface for the connector 3 to cooperate with the shell 1. In this embodiment, the vertical mounting surface is in abutment with the floating plate 4 and does not need to be in abutment with the side of the shell 1, which can reduce the production and installation difficulty and installation accuracy requirements of the connector 3 to a certain extent.

[0046] In some optional embodiments, see Figures 1 to 6 As shown, an embodiment of the present application provides a connector floating installation structure, wherein the housing 1 and the floating plate 4 of the connector floating installation structure are both made of conductive materials, and the colloid is conductive glue.

[0047] In the embodiment of the present application, both the housing 1 and the floating plate 4 are made of conductive materials. Furthermore, the adhesive bonding the housing 1 and the floating plate 4 is conductive adhesive. This prevents electromagnetic leakage from the gaps between the adhesive and could affect the electromagnetic shielding effect. Specifically, in this embodiment, the conductive adhesive allows the housing 1 and the floating plate 4 to form a conductive, integrated structure, effectively ensuring electromagnetic shielding. For example, the housing 1 and the floating plate 4 can be made of metals such as copper, aluminum, and steel.

[0048] In some optional embodiments, see Figures 1 to 6 As shown, an embodiment of the present application provides a connector floating mounting structure, in which the floating plate 4 and the shell 1 of the connector floating mounting structure form a clearance fit by plugging, and the clearance path formed by the floating plate 4 and the mounting hole 12 is a multi-bending path.

[0049] In the embodiment of the present application, the floating plate 4 is mounted to the housing 1 via a plug-in connection. The gap path formed by the floating plate 4 and the mounting hole 12 is a multi-fold path. This multi-fold path facilitates the reflection and absorption of magnetic signals, effectively ensuring electromagnetic shielding. For example, the multi-fold path can adopt a maze structure similar to an "L" or "U" shape, both of which effectively prevent or minimize the leakage of magnetic signals within the housing 1, thereby ensuring the reliability of the mounting structure.

[0050] In some optional embodiments, see Figures 1 to 6 As shown, an embodiment of the present application provides a connector floating mounting structure, wherein the housing 1 of the connector floating mounting structure has a first opening 111 for the printed circuit board 2 to be installed in the cavity 11 , and a second opening 121 for the floating board 4 to be inserted into the mounting hole 12 .

[0051] In the embodiment of the present application, the top side of the housing 1 is left open to form a first opening 111 communicating with the cavity 11 within the housing 1. The printed circuit board 2 can be vertically inserted into the cavity 11 through the first opening 111 and aligned with the housing 1. Furthermore, during the insertion of the printed circuit board 2, to ensure that the floating plate 4 is inserted into the mounting hole 12, the upper portion of the mounting hole 12 is left open to form a second opening 121.

[0052] This allows the floating plate 4 to be inserted into the mounting hole 12 while the printed circuit board 2 is being installed into the housing 1, thereby improving installation convenience. The housing 1 can then be covered with a cover 5 to close the first opening 111 and the second opening 121.

[0053] In some optional embodiments, see Figures 1 to 6 As shown, an embodiment of the present application provides a connector floating mounting structure, in which a slot 13 is provided on the wall surface of the mounting hole 12 of the connector floating mounting structure, and an insert 41 protruding outward and loosely fitting with the slot 13 is provided on the floating plate 4.

[0054] A slot 13 is provided on the wall surface of the mounting hole 12 in the embodiment of the present application, and an insert block 41 is protruded on the end surface of the peripheral side of the floating plate 4. When the floating plate 4 is inserted into the mounting hole 12, the insert block 41 can slide along the slot 13 and form a gap path with multiple bends to effectively ensure the electromagnetic shielding effect.

[0055] In some optional embodiments, see Figures 1 to 6 As shown, an embodiment of the present application provides a connector floating mounting structure, in which the slot 13 of the connector floating mounting structure has a first side wall 131 facing the interior of the shell 1, and a second side wall 132 opposite to the first side wall 131. When viewed in the direction of the connector 3 extending out of the mounting hole 12, the first side wall 131 exceeds the second side wall 132.

[0056] The first side wall 131 and the second side wall 132 of the slot 13 in the embodiment of the present application are opposite to and parallel to each other. The first side wall 131 and the second side wall 132 can limit the floating plate 4 to prevent the floating plate 4 from detaching from the mounting hole 12 in the direction of extending from the connector 3, thereby effectively bearing the plugging and unplugging force of the plug connector on the connector 3.

[0057] Furthermore, in this embodiment, the first sidewall 131 faces the interior of the housing 1 and is larger than the second sidewall 132. Consequently, when viewed from the direction in which the connector 3 extends out of the mounting hole 12, the first sidewall 131 extends beyond the second sidewall 132. Before installing the floating plate 4, an external adhesive dispenser can be conveniently slid along the first sidewall 131 to apply adhesive. By shaking the housing 1, the adhesive can flow along the first sidewall 131 and fill the slot 13, enhancing installation convenience.

[0058] In some optional embodiments, see Figures 1 to 6 As shown, an embodiment of the present application provides a connector floating mounting structure, in which one end of the connector 3 of the connector floating mounting structure is provided with a welding foot 31 welded and fixed to the printed circuit board 2, and ear plates 32 located on both sides of the welding foot 31 and connected to the printed circuit board 2 through fasteners.

[0059] The connector 3 of the present embodiment has solder pins 31 extending from one end. A pair of integrally formed lugs 32 are formed on either side of the solder pins 31. The lugs 32 have mounting holes for conveniently installing screws to connect the lugs 32 to the printed circuit board 2. In other words, with the present embodiment's floating mounting structure, soldering of the solder pins 31 can be performed directly after the lugs 32 are secured to the printed circuit board 2, eliminating the need to install the housing 1 before performing the soldering operation. This reduces installation complexity.

[0060] In some optional embodiments, see Figures 1 to 6 As shown, an embodiment of the present application provides a connector floating installation structure, in which a circle of flanges 33 are provided on the connector 3 of the connector floating installation structure, a circle of grooves 42 for positioning the flanges 33 are provided on the floating plate 4, and the flanges 33 are connected to the floating plate 4 by fasteners.

[0061] The floating plate 4 and the connector 3 of the embodiment of the present application are connected by fastening screws. To facilitate the installation of the fastening screws, a circle of flanges 33 are integrally formed on the connector 3, and a pair of threaded holes are provided on the flange 33. At the same time, a circle of grooves 42 and a pair of assembly holes connected to the grooves 42 are provided on the floating plate 4. When the floating plate 4 is mounted on the connector 3, the flanges 33 can abut against the wall of the grooves 42, and then fastening screws are passed through the assembly holes to connect the threaded holes.

[0062] In some optional embodiments, see Figures 1 to 6As shown, an embodiment of the present application provides a connector floating installation structure, in which a limiting column 14 for supporting a printed circuit board 2 is provided in a housing 1 of the connector floating installation structure, and the printed circuit board 2 is connected to the limiting column 14 by fasteners.

[0063] The shell 1 of the embodiment of the present application has multiple groups of limiting columns 14 integrally formed therein for supporting the printed circuit board 2. The limiting columns 14 are provided with threaded holes for docking with the assembly holes on the printed circuit board 2. When the printed circuit board 2 is aligned with the limiting columns 14, it is convenient to install fastening screws to lock the printed circuit board 2 on the limiting columns 14.

[0064] In some optional embodiments, see Figures 1 to 6 As shown, an embodiment of the present application provides a connector floating installation structure, in which a cover 5 for enclosing the shell 1 is installed on the shell 1, a positioning groove 15 is provided on the shell 1, and a docking groove 51 cooperating with the positioning groove 15 is provided on the cover 5.

[0065] The housing 1 of the present embodiment is mounted with a cover 5 to form a closed structure, ensuring structural reliability. Furthermore, a circle of positioning grooves 15 are provided on the side of the housing 1, and a circle of docking grooves 51 are provided on the edge of the cover 5. The alignment of the positioning grooves 15 and the docking grooves 51 facilitates the installation of screws to lock the cover 5 and the housing 1. Furthermore, a curved path is formed between the housing 1 and the cover 5, effectively preventing or minimizing magnetic signal leakage, thereby ensuring the reliability of the mounting structure.
