Description

Technical Field

[0001] This invention relates to the field of electrical connectors that allow relative movement between coupling components, such as floating or automatic docking, and particularly to a floating socket and a floating connector using the floating socket. Background Technology

[0002] When multiple connectors are needed to transmit current or signals between circuit boards, floating connectors are typically used. The main components of a floating connector include a plug and a socket. A floating structure is usually incorporated into the socket to absorb misalignment and vibration generated during board mounting when the plug and socket are mated. Floating connectors are particularly suitable for applications requiring high contact reliability under vibration conditions, such as automotive, commercial displays, wearable devices, and medical devices. To meet the needs of these applications, connectors are also trending towards miniaturization, weight reduction, and high-density nodes, which places even higher demands on their heat dissipation efficiency.

[0003] Currently, floating connectors used between circuit boards mostly employ a method where contacts (also known as terminals) are forcibly embedded in an insulator to fix the contacts, with the insulator surrounding the contacts. This structure affects the airflow around the contacts, limiting their heat dissipation efficiency. Furthermore, these connectors are relatively large, occupying a significant amount of board space, which is detrimental to the miniaturization of integrated products.

[0004] To address the aforementioned issues, a floating connector exists in the prior art, disclosed in Japanese patent application JP2000260527A. This floating connector includes a plug and a floating socket. The floating socket comprises an adapter plate (fixed insulator), a floating insulator, and a socket terminal connected between the adapter plate and the floating insulator. The plug-in end of the socket terminal, i.e., the end for plugging into the adapter terminal, is located on the floating insulator, while the fixed end, i.e., the end furthest from the plug-in end, is located on the adapter plate. In use, the fixed end of the socket terminal is soldered to the printed circuit board, thereby fixing the adapter plate to the printed circuit board. The floating insulator is supported above the adapter plate by the socket terminal, with the two spaced apart. This exposes the portion between the fixed end and the plug-in end of the socket terminal, thus achieving higher heat dissipation efficiency.

[0005] While the aforementioned floating connector improves heat dissipation efficiency by exposing the socket terminals, relying solely on the socket terminals to support the floating insulator may not be sufficient to withstand the insertion resistance of the plug, potentially leading to socket damage. To avoid this problem, the floating socket of the aforementioned floating connector also includes limiters at both ends. The limiters are provided with limit grooves. During use, the limiters are inserted between the floating insulator and the adapter plate in a direction perpendicular to the insertion direction. A movable gap is left between the side wall of the limit groove and the plug housing, and a movable gap is left between the bottom surface of the limit groove and the corresponding surface of the plug housing. This allows the plug to float relative to the floating socket while limiting the deformation of the socket terminals, thereby protecting the floating socket.

[0006] The inclusion of components such as floating insulators, fixed insulators, and limiters makes the structure of the aforementioned floating connectors overly complex, which will increase manufacturing costs to some extent. In particular, the limiter, as a separate component, needs to be assembled with the socket on-site during use, i.e., installation of the floating socket. This makes the installation process extremely complicated, and when many connectors need to be installed on-site, the limiter, being a small part, is at risk of being lost. Utility Model Content

[0007] The purpose of this invention is to provide a floating socket to solve the problems of complex structure and inconvenient installation of existing floating sockets with good heat dissipation.

[0008] Meanwhile, the purpose of this utility model is also to provide a floating connector that uses the above-mentioned floating socket.

[0009] To solve the above problems, the floating socket of this utility model adopts the following technical solution: The floating socket includes a fixed base, a floating insulator, and socket terminals. The fixed base includes a fixed insulator. The fixed end of the socket terminal is disposed on the fixed insulator, and the plug-in end is disposed on the floating insulator. The floating insulator is supported by the socket terminals, and a convection heat dissipation gap for the socket terminals is formed between the floating insulator and the fixed base. At the periphery of the convection heat dissipation gap, one of the floating insulator and the fixed base is provided with a limiting body protruding towards the other, and the other is provided with a limiting socket corresponding to the limiting body. The limiting body extends into the corresponding limiting socket and a floating gap is provided between it and the inner sidewall of the limiting socket. The floating amount of the floating insulator relative to the fixed base in the direction perpendicular to the socket plug-in direction can be limited by the cooperation of the limiting body and the limiting socket.

[0010] Furthermore, the limiting body is disposed on the floating insulator, and the limiting socket penetrates the fixed insulator in the insertion direction of the socket. The limiting body extends to one end of the corresponding limiting socket to form a support end for cooperating with the printed circuit board to limit the compression of the socket terminal in the socket insertion direction.

[0011] Furthermore, the fixing base also includes a cover covering the fixed insulator, the cover having a clearance opening to avoid the limiting body, and the limiting body having a stop surface that cooperates with the inner opening of the clearance opening to prevent the floating insulator from detaching from the fixing base in a direction opposite to the insertion direction of the socket.

[0012] Furthermore, the anti-detachment surface is composed of a stepped surface provided on the corresponding limiting body.

[0013] Furthermore, the housing is provided with a printed circuit board connection structure for fixed connection with the printed circuit board.

[0014] Furthermore, the printed circuit board connection structure is a cover solder foot formed by an outward fold on the cover.

[0015] Furthermore, the size of the clearance opening is larger than the outer contour size of the floating insulator, and the cover is fitted onto the fixed insulator from the plug end of the socket.

[0016] Furthermore, the socket terminals are divided into two rows, and the fixed insulator is divided into two parts corresponding to the two rows of socket terminals, with the two parts respectively fixedly installed on the cover.

[0017] Furthermore, the two parts of the fixed insulator are arranged at intervals, and the support end passes through the interval between them in the support direction.

[0018] Furthermore, the housing is provided with an elastic clamp, which together with the inner wall of the housing forms a clamping opening. The inlet of the clamping opening is away from the floating insulator, and the two parts of the fixed insulator are respectively clamped and fixed in the corresponding clamping opening.

[0019] Furthermore, the elastic clamp is formed by bending a sheet material that is integral with the cover.

[0020] Furthermore, slots are provided on both parts of the fixed insulator, and elastic claws corresponding to the slots are provided on the wall of the cover. The elastic claws are engaged in the corresponding slots to prevent the cover from separating from the fixed insulator along the socket insertion direction.

[0021] Furthermore, the elastic claws and elastic clamps are distributed on opposite sides of the same position of the corresponding part of the fixed insulator.

[0022] Furthermore, the socket terminals are arranged in at least one row, and the limiting body is provided at both ends of the row formed by the socket terminals.

[0023] Furthermore, the socket terminals are divided into two rows, and the fixed insulator is divided into two parts corresponding to the two rows of socket terminals, with the two parts respectively fixedly installed on the cover.

[0024] Furthermore, a recess is provided at the plug end of the socket terminal for engaging with the adapter terminal to obtain a gentle insertion and extraction force.

[0025] Beneficial Effects: This invention relates to an improved floating socket. Specifically, by setting limiting bodies and limiting sockets on the floating insulator and fixed base of the floating socket respectively, and by extending the limiting body into the corresponding limiting socket and setting a floating gap between the limiting body and the inner wall of the limiting socket, the floating amount of the floating insulator relative to the fixed base in the direction perpendicular to the socket insertion is limited by the cooperation of the limiting body and the limiting socket. Therefore, it is unnecessary to use external parts to limit the floating insulator and fixed base. Since the limiting body is located outside the convection heat dissipation interval, it will not affect the heat dissipation efficiency of the socket terminals. Thus, while ensuring heat dissipation efficiency, the number of parts in the floating socket can be reduced, simplifying its structure and achieving the effects of convenient installation and reduced costs.

[0026] The floating connector of this utility model adopts the following technical solution:

[0027] A floating connector includes a plug and a socket. The socket includes a fixed base, a floating insulator, and socket terminals. The fixed base includes a fixed insulator. The fixed end of the socket terminal is disposed on the fixed insulator, and the plug end is disposed on the floating insulator. The floating insulator is supported by the socket terminals, forming a convective heat dissipation gap between the floating insulator and the fixed base. At the periphery of the convective heat dissipation gap, one of the floating insulator and the fixed base is provided with a limiting body protruding towards the other, and the other is provided with a limiting socket corresponding to the limiting body. The limiting body extends into the corresponding limiting socket and a floating gap is provided between it and the inner sidewall of the limiting socket. The floating amount of the floating insulator relative to the fixed base in the direction perpendicular to the socket plugging direction can be limited by the cooperation of the limiting body and the limiting socket.

[0028] Furthermore, the limiting body is disposed on the floating insulator, and the limiting socket penetrates the fixed insulator in the insertion direction of the socket. The limiting body extends to one end of the corresponding limiting socket to form a support end for cooperating with the printed circuit board to limit the compression of the socket terminal in the socket insertion direction.

[0029] Furthermore, the fixing base also includes a cover covering the fixed insulator, the cover having a clearance opening to avoid the limiting body, and the limiting body having a stop surface that cooperates with the inner opening of the clearance opening to prevent the floating insulator from detaching from the fixing base in a direction opposite to the insertion direction of the socket.

[0030] Furthermore, the anti-detachment surface is composed of a stepped surface provided on the corresponding limiting body.

[0031] Furthermore, the housing is provided with a printed circuit board connection structure for fixed connection with the printed circuit board.

[0032] Furthermore, the printed circuit board connection structure is a cover solder foot formed by an outward fold on the cover.

[0033] Furthermore, the size of the clearance opening is larger than the outer contour size of the floating insulator, and the cover is fitted onto the fixed insulator from the plug end of the socket.

[0034] Furthermore, the socket terminals are divided into two rows, and the fixed insulator is divided into two parts corresponding to the two rows of socket terminals, with the two parts respectively fixedly installed on the cover.

[0035] Furthermore, the two parts of the fixed insulator are arranged at intervals, and the support end passes through the interval between them in the support direction.

[0036] Furthermore, the housing is provided with an elastic clamp, which together with the inner wall of the housing forms a clamping opening. The inlet of the clamping opening is away from the floating insulator, and the two parts of the fixed insulator are respectively clamped and fixed in the corresponding clamping opening.

[0037] Furthermore, the elastic clamp is formed by bending a sheet material that is integral with the cover.

[0038] Furthermore, slots are provided on both parts of the fixed insulator, and elastic claws corresponding to the slots are provided on the wall of the cover. The elastic claws are engaged in the corresponding slots to prevent the cover from separating from the fixed insulator along the socket insertion direction.

[0039] Furthermore, the elastic claws and elastic clamps are distributed on opposite sides of the same position of the corresponding part of the fixed insulator.

[0040] Furthermore, the socket terminals are arranged in at least one row, and the limiting body is provided at both ends of the row formed by the socket terminals.

[0041] Furthermore, the socket terminals are divided into two rows, and the fixed insulator is divided into two parts corresponding to the two rows of socket terminals, with the two parts respectively fixedly installed on the cover.

[0042] Furthermore, a recess is provided at the plug end of the socket terminal for engaging with the adapter terminal to obtain a gentle insertion and extraction force.

[0043] Beneficial Effects: The floating connector of this utility model is an improved invention. Specifically, by setting a limiting body and a limiting socket on the floating insulator and the fixed base of its socket respectively, and by extending the limiting body into the corresponding limiting socket and setting a floating gap between the limiting body and the inner sidewall of the limiting socket, the floating amount of the floating insulator relative to the fixed base in the direction perpendicular to the socket insertion is limited by the cooperation of the limiting body and the limiting socket. Thus, it is not necessary to use external parts to limit the floating insulator and the fixed base. Since the limiting body is located outside the convection heat dissipation interval, it will not affect the heat dissipation efficiency of the socket terminals. Therefore, while ensuring heat dissipation efficiency, the number of parts of the floating socket can be reduced, its structure can be simplified, thereby achieving the effects of convenient installation and reduced cost.

[0056] The features and performance of this utility model will be further described in detail below with reference to the embodiments.

[0057] To address the requirements of high heat dissipation efficiency and the ability to float to adapt to mating deviations and absorb vibration in inter-board connectors (connectors used to connect printed circuit boards), a more ideal solution is to directly support the connector between spaced fixed and floating insulators using socket terminals, creating a convection gap between them. Simultaneously, it is necessary to ensure that the socket terminals do not undergo excessive deformation during use to protect them. In existing technologies, protection of the socket terminals is achieved by inserting limiters between the fixed and floating insulators. This, to some extent, complicates the structure of the inter-board connector, especially the floating socket 1, and increases its installation difficulty.

[0058] If the structure protecting the socket terminals can be integrated into the fixed insulator and / or floating insulator of the floating socket 1 without affecting the convection efficiency of the aforementioned convection interval, the aforementioned problems of complex structure and inconvenient installation will be solved. The technical solution of the floating socket 1 of this utility model is proposed based on the above inventive concept. By setting a limiting body and a limiting socket between the fixed part of the socket terminal and the floating insulator, the limiting body and the limiting socket cooperate to form a limiting structure, thereby realizing the integration of the socket terminal protection structure into the floating part and fixed part of the floating socket. By setting the limiting structure outside the convection heat dissipation interval, the heat dissipation of the socket terminals can be avoided.

[0059] Based on the above inventive concept, the basic solution of the floating socket of this utility model is as follows:

[0060] The floating socket 1 includes a fixed base 101, a floating insulator 102, and a socket terminal 103. The fixed base 101 includes a fixed insulator 1011. The fixed end 1031 of the socket terminal 103 is disposed on the fixed insulator 1011, and the plug-in end 1032 is disposed on the floating insulator 102. The floating insulator 102 is supported by the socket terminal 103. A convection heat dissipation gap 104 is formed between the floating insulator 102 and the fixed base 101 for the socket terminal 103. At the periphery of 04, one of the floating insulator 102 and the fixed base 101 is provided with a limiting body 105 protruding towards the other, and the other is provided with a limiting socket 106 corresponding to the limiting body. The limiting body 105 extends into the corresponding limiting socket 106 and a floating gap is provided between it and the inner sidewall of the limiting socket 106. The floating amount of the floating insulator 102 relative to the fixed base 101 in the direction perpendicular to the socket insertion direction can be limited by the cooperation of the limiting body 105 and the limiting socket 106.

[0061] The mounting base 101 is used to fix and connect the floating socket 1 to the corresponding printed circuit board (not shown in the figure) during use, serving as the base for fixing the socket terminal 103 and supporting the floating insulator 102. Since it is used to fix the fixed end 1031 of the socket terminal 103, the mounting base 101 includes a fixing insulator 1011. Under the condition of meeting the fixing requirements, the mounting base 101 can be composed only of the fixing insulator. For example, the fixing insulator is provided with a connection structure for fixing and connecting with the printed circuit board. Typically, the connection structure can be a screw hole, a hole, a solder pad, etc., as long as it can achieve a fixed connection with the printed circuit board. They will not be listed one by one here.

[0062] The main function of the floating insulator 102 is to constrain and retain the insertion end 1032 of the socket terminal 103, enabling it to form a compliant female or male connector. During use, the force between the floating insulator 102 and the housing or insulator of the plug 2 guides the initially misaligned plug 2 and socket to the correct insertion path. For example, in... Figure 2 and Figure 3 In the illustrated embodiment, an opening is provided in the middle of the floating insulator 102, which allows the tongue with plug terminal 201 on the plug 2 to be inserted during use, thereby connecting the plug 2 to the socket. In the above or similar embodiments, the floating insulator 102 makes the plug end of the floating socket 1 a female connector. It can be understood that when it is necessary to make the plug end of the floating socket 1 a male connector, the plug end of the socket terminal 103 can be arranged on its outer wall, thus forming a male connector structure.

[0063] The fixed end 1031 of the socket terminal 103 is used to connect to the corresponding line on the printed circuit board, and the plug end 1032 is used to connect to the corresponding plug terminal; this is common knowledge in the art. Therefore, it is a necessary structure that the fixed end 1031 of the socket terminal 103 is located on the fixed insulator 1011 and has a socket soldering part, while the plug end 1032 is located on the floating insulator 102. In some cases, such as... Figure 2 As shown, the plug-in end of the socket terminal 103 can be directly fixed to the floating insulator while the floating insulator 102 is being formed, making the two an integral structure. Similarly, the fixed end of the socket terminal 103 can be directly fixed to the fixed insulator while the fixed insulator 1011 is being formed, making the two an integral structure. The above-mentioned forming process can be, for example, injection molding. Of course, in other cases, a forced-fit structure can also be used between the socket terminal 103 and the floating insulator 102 and the fixed insulator 1011, such as a plug-in or other fixed structure.

[0064] To enable the floating insulator 102 to have a certain amount of floating, it must be supported by an elastic component. Since the floating connectors involved in this invention often have small dimensions, the space for additional support components is inevitably insufficient. Therefore, the floating insulator 102 is directly supported by an elastic socket terminal 103. The convection heat dissipation gap 104 formed between the floating insulator 102 and the fixed base 101 refers to a certain gap between the floating insulator 102 and the fixed base 101 in the direction in which the socket terminal 103 supports the floating insulator 102. At this time, a portion of the socket terminal 103 will be exposed. Through convection at the gap, i.e., airflow, the heat dissipation efficiency of the socket terminal 103 can be improved. As mentioned above, for the convection heat dissipation gap 104 to achieve "convection," the gap must be unobstructed in at least one direction, for example, in… Figure 1 In the illustrated embodiment, the space is permeable (partially or completely permeable) in a direction perpendicular to the paper surface, thereby forming the convection heat dissipation space 104. Of course, in other embodiments, it could also be... Figure 1 The two ends of the gap shown are kept open in the left and right directions, so that convection heat dissipation gap 104 can still be formed.

[0065] In one embodiment, such as Figure 2 , 5 As shown in Figure 6, to improve the elasticity of the socket terminal 103, a deformable portion 1033 is provided on the socket terminal 103. This deformable portion is U-shaped. During use, this deformable portion 1033 will become the main deformation point when the floating insulator 102 moves relative to the fixed base 101. For example, Figure 2 Deformation in the left-right direction and deformation perpendicular to the paper surface, etc. Furthermore, in Figure 2 ,5 In the embodiments shown in 6, the socket terminal 103 is further provided with a fixed insulator mating part 1034, a floating insulator mating part 1035, and a printed circuit board connecting part 1036. The fixed insulator mating part 1034 and the floating insulator mating part 1035 are both bent structures, which can more firmly mate with the corresponding insulator and prevent it from falling out. The part between the fixed insulator mating part 1034 and the floating insulator mating part 1035 constitutes a support part, which mainly provides support for the floating insulator 102. The printed circuit board connecting part 1036 is a flat section with a soldering area formed on it, which can be connected to the printed circuit board by surface mounting soldering during use.

[0066] In a more preferred embodiment, a recess 1037 for engaging with a mating terminal is provided at the insertion end of the socket terminal 103 to obtain a gentle insertion and extraction force. Of course, those skilled in the art should understand that the recess 1037 is not a necessary structure for the socket terminal 103, and in other embodiments, the surface at the insertion end may also be flat.

[0067] To minimize any adverse impact on the heat dissipation efficiency of the convection heat dissipation interval 104, a limiting structure for restricting the deformation of the socket terminal 103 between the floating insulator 102 and the fixed base 101 is located at the periphery of the convection heat dissipation interval 104. Therefore, one of the floating insulator 102 and the fixed base 101 has a limiting body 105 protruding towards the other, and the other has a limiting socket 106 corresponding to the limiting body 105. The limiting body 105 extends into the corresponding limiting socket 106 and has a floating gap between it and the inner wall of the limiting socket 106. The cooperation between the limiting body 105 and the limiting socket 106 restricts the amount of floating of the floating insulator 102 relative to the fixed base 101 in the direction perpendicular to the socket insertion. The aforementioned limiting body 105 and limiting socket 106 constitute the limiting structure, which is arranged at the periphery of the convection heat dissipation interval 104.

[0068] As mentioned above, the limiting body 105 primarily functions to cooperate with the limiting socket 106 to limit the floating amount of the floating insulator 102 relative to the fixed base 101. Therefore, while meeting this functional requirement, the shape of the limiting body 105 should be unrestricted. For example, it can be a cylinder with a circular or rectangular cross-section, or an irregular shape, such as a ridge shape. Furthermore, the limiting body 105 is integrated with the fixed base 101 or the floating insulator 102. It can be an integral structure or a fixed-installation structure. When a fixed-installation structure is used, the limiting body 105 can be connected to its carrier by screws, adhesive, welding, or other methods. Correspondingly, the configuration and shape of the limiting socket 106 are also unrestricted, as long as the aforementioned functional requirements are met.

[0069] Based on the above basic scheme, as a preferred implementation method, such as Figure 1 , 2 As shown in Figures 3 and 4, the limiting body 105 is disposed on the floating insulator 102, and the limiting socket 106 penetrates the fixed insulator 1011 in the socket insertion direction. The limiting body 105 extends to one end of the corresponding limiting socket 106 to form a support end 1051 for cooperating with the printed circuit board to limit the compression amount of the socket terminal 103 in the socket insertion direction.

[0070] Since the installation of the floating socket 1 involves mounting the fixed base 101 onto the printed circuit board, placing the limiting body 105 on the floating insulator 102 will minimize unwanted interference with the installation of the fixed base 101, facilitating its installation. The limiting socket 106 penetrates the fixed insulator 1011 in the socket's insertion direction. In other words, a channel is formed on the fixed insulator 1011 for objects to pass through, allowing the limiting body 105 to pass through. This allows one end of the limiting body 105 extending into the limiting socket 106 to pass through the fixed insulator 1011. When the floating insulator 102 compresses the socket terminal 103 in the direction opposite to the socket's insertion direction, the end of the limiting body 105 inserted into the limiting socket 106 can directly or indirectly abut against the printed circuit board, limiting the amount of compression of the socket terminal 103 and protecting it. This allows the end of the limiting body extending into the limiting socket to form a support end 1051.

[0071] Based on the above embodiments, as a preferred embodiment, the fixing base 101 further includes a cover 1012 covering the fixing insulator 1011. The cover 1012 is provided with a clearance opening to avoid the limiting body 105. The limiting body 105 is provided with a stop surface 1052 that cooperates with the inner opening of the clearance opening to prevent the floating insulator 102 from disengaging from the fixing base 101 in a direction opposite to the insertion direction of the socket.

[0072] With the cover 1012 in place, the cover 1012 can cooperate with the limiting body 105 to limit the limiting body 105 in the socket opening direction, thereby preventing excessive floating of the floating insulator 102 in the socket insertion direction, and thus avoiding excessive positional deviation of the floating insulator 102 when in standby due to excessive floating. The anti-disengagement surface 1052 functions to cooperate with the cover 1012 to form a hook effect, therefore the anti-disengagement surface 1052 can be used as follows: Figure 3 As shown, it is formed by the stepped surface provided on the corresponding limiting body 105. Of course, in other embodiments, the anti-detachment surface 1052 can also be formed by providing a protruding structure on the limiting body 105, with the surface of the protruding structure serving as the anti-detachment surface. When a protruding structure is provided, the protruding structure can be integrally formed with the limiting body or fixedly installed on the limiting body.

[0073] In another preferred embodiment, when a cover 1012 is provided, the cover 1012 is provided with a printed circuit board (PCB) connection structure for fixed connection with the PCB. The PCB connection structure cooperates with the PCB to fix the cover 1012 to the PCB, achieving the effect of reinforcing the mounting base. Figure 5 In the illustrated embodiment, the printed circuit board (PCB) connection structure is an outwardly flared cover solder foot 10121 provided on the cover. In other embodiments, the PCB connection structure can also be a bolt hole, a riveting hole, or a structure that can cooperate with an adhesive, as long as it can fix the cover 1012 to the PCB.

[0074] As a preferred embodiment, the size of the clearance opening on the housing 1012 is larger than the outer contour size of the floating insulator 102, and the housing 1012 is fitted onto the fixed insulator 1011 from the insertion end of the socket. By setting the size of the clearance opening to meet the above requirements, the housing 1012 can be manufactured and installed as a single unit, which simplifies the overall structure of the floating socket to a certain extent, simplifies its installation process, and reduces costs. Of course, when the housing 1012 adopts a split-assembly structure, the above requirements do not need to be met, that is, in the floating socket 1 of this utility model, the above structural features are not unique.

[0075] In the field of injection molding, it is common knowledge that the larger the part size, the lower the yield rate. This is because when the part size reaches a certain value, uneven material distribution, uneven heating and cooling, material shrinkage, and mechanical stress concentration can occur, ultimately leading to part manufacturing failure. To avoid this problem, as a preferred implementation method, such as... Figure 7 As shown, the socket terminals 103 of this utility model are divided into two rows. The fixing insulator 1011 is divided into two parts corresponding to the two rows of socket terminals. Here, these two parts are defined as two sub-blocks 10111. When a cover 1012 is used, the two sub-blocks 10111 are fixedly installed on the cover 1012. In the above embodiment, each part of the fixing insulator is an integral structure. In other embodiments, each part of the fixing insulator can also be a separate structure.

[0076] To minimize the size of the fixed insulator 1011 and save on material, the sub-blocks 10111 of the fixed insulator are designed with smaller dimensions. This allows the two parts of the fixed insulator 1011 to be spaced apart, with the gap between them forming a channel. The support end 1051 passes through the gap between the two parts in the supporting direction. Since the gap between the two sub-blocks 10111 has a structure that is wider at the top and narrower at the bottom, the support end of the limiting body 105 is correspondingly designed to be wider at the top and narrower at the bottom, forming a T-shape. Following this approach, the number of sub-blocks 10111 can certainly be increased. In this case, the socket terminals 103 can be divided into more rows, and the limiting bodies 105 can be set at both ends of the rows formed by the socket terminals 103.

[0077] When the sub-blocks of the fixed insulator 1011 are fixed to the housing 1012, an elastic clamping plate 10122 can be provided in the housing 1012. The elastic clamping plate 10122 and the inner wall of the housing together form a clamping opening. The inlet of the clamping opening is away from the floating insulator 102, and the two sub-blocks of the fixed insulator 1011 are respectively clamped and fixed in the corresponding clamping opening. The elastic clamping plate 10122 can be formed by bending a plate integral with the housing, or it can be fixed to the side wall of the housing 1012 by welding, pressing or other processes. Of course, the method of fixing the sub-blocks to the housing is not unique. In some embodiments, the sub-blocks can also be fixed in the housing by bonding, screw connection or other methods.

[0078] When the sub-block 10111 is fixed using the elastic clamp 10122, as a preferred embodiment, slots 101111 are respectively provided on both parts of the fixed insulator 1011, and elastic claws 10123 corresponding to the slots are provided on the wall of the cover 1012. The elastic claws 10123 are engaged in the corresponding slots to prevent the cover 1012 from separating from the fixed insulator along the socket insertion direction. At this time, the elastic claws form a barb-like structure, which can further prevent the sub-block 10111 from detaching from the aforementioned clamps. When the optimal fixing effect is desired, the elastic claws 10123 and the elastic clamp 10122 can interact with each other. In this case, the elastic claws 10123 and the elastic clamp 10122 are distributed on opposite sides of the same position on the corresponding part of the fixed insulator. For example... Figure 5 The structure is shown in the figure, in which the elastic claw 10123 and the elastic clamp 10122 are located at the same position along the length of the housing 1012.

[0079] The specific implementation method of the floating connector of this utility model is as follows:

[0080] like Figure 1-11 As shown, the floating connector includes a plug 2 and a floating socket 1. The floating socket 1 is the floating socket of this invention, and its structure can be referenced from the embodiment of the floating socket 1 of this invention. The plug 2 includes a plug insulator 201, a plug terminal 202, and a fixing piece 203. The plug terminal 202 transmits signals by contacting the plug end of the socket terminal 103 through its contact portion 2021. The interference fit structure 2022 on the plug terminal 202 cooperates with the plug insulator 201 to fix the plug terminal 202. The plug soldering portion 2023 on the plug terminal 202 can be surface-mounted and soldered to the circuit board during use, enabling the transmission of printed circuit board signals through the plug and socket. The fixing piece 203 is connected to the circuit board through the fixing piece soldering portion 2031 via surface-mount soldering, strengthening the fixing strength of the plug 2 on the printed circuit board and helping to ensure the reliability of the product in harsh environments. The strong mounting portion 2032 on the fixing piece 203 cooperates with the plug insulator 201 to fix the fixing piece 203.

The patent protection scope of the present utility model shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present utility model shall also be included within the protection scope of the present utility model.
