Description

Technical Field

[0001] This invention relates to the field of electrical connectors, and in particular to a floating socket and a floating connector. Background Technology

[0002] In the design of power or signal transmission for chassis and cabinet interfaces, floating connectors are often used to connect the horizontal PCB board and the vertical panel of the chassis or cabinet (L-shaped or diagonal) to achieve current transmission or signal control.

[0003] When installing a connection system, it's typically required to install the vertical panel-side socket first, followed by the horizontal printed circuit board-side socket. To compensate for the positional difference between the vertical panel-side and horizontal printed circuit board-side sockets and ensure smooth connection, an adapter is usually installed between them. This adapter is installed in a floating manner. Specifically, the adapter housing has a connecting edge with a floating sleeve. During installation, the adapter is mounted on the base plate of the chassis or cabinet by fastening screws through the floating sleeve. The floating of the adapter is achieved by the gap between the floating sleeve and the connecting edge.

[0004] Although the above connection scheme achieves a misaligned connection between the vertical panel side socket and the horizontal printed circuit board side socket, it has the problems of many installation materials and steps, resulting in high costs. In addition, the use of adapters fixed on the base plate for the adapters occupies too much space inside the cabinet. Summary of the Invention

[0005] The purpose of this invention is to provide a floating socket to solve the problems of multiple installation steps and large space occupation in the floating connection mechanism between two components connected at an angle.

[0006] Furthermore, the present invention also aims to provide a floating connector using the aforementioned floating socket.

[0007] To achieve the above objectives, the technical solution of the floating socket of the present invention is: a floating socket, comprising:

[0008] case;

[0009] At least one connecting component, the connecting component including a contact and a connecting insulator for fixing the contact, the contact having a first plug-in end and a second plug-in end, the plug-in directions of the first plug-in end and the second plug-in end forming a set angle, the set angle being greater than 0° and less than 180°;

[0010] The connecting component is floatingly mounted on the housing along the insertion direction of the first insertion end of the contact and is anti-detached from the housing; the connecting insulator includes a housing mating section, and the width of the mating portion on the housing that mates with the housing mating section in the insertion direction of the first insertion end is greater than the width of the housing mating section, providing conditions for the aforementioned floating of the connecting component.

[0011] Beneficial effects: In the floating socket of the present invention, the connecting component is floatingly mounted on the housing along the insertion direction of the first insertion end of its contact member, and adopts an anti-disengagement structure directly with the housing. Therefore, it has the function of a floating adapter in the prior art. When in use, there is no need to install a floating adapter on a fixed object such as a chassis or cabinet. It can be directly plugged into the matching connector, thereby solving the problem of multiple installation steps and large space occupation of the floating connection mechanism between two components connected at an angle.

[0012] Furthermore, the connecting component is equipped with a sliding pad. The sliding pad reduces resistance to the movement of the connecting component, ensuring reliable operation, and also slows down wear, extending its lifespan.

[0013] Furthermore, one side of the sliding pad mates with the connecting insulator.

[0014] Furthermore, the connecting component is provided with a guide and positioning component for mating with the adapter connector. The guide and positioning component can play a "correction" role, automatically aligning the connecting component when it is inserted with a misalignment into the adapter connector.

[0015] Furthermore, a supporting insulator is assembled within the housing, and the connecting component is installed within the supporting insulator. Installing the connecting component within the supporting insulator reduces the structural requirements of the housing and simplifies the overall manufacturing complexity of the floating socket.

[0016] Furthermore, the supporting insulator has a modular, spliced ​​structure. After its various parts are spliced ​​and fixed, the connecting components are confined within the housing to prevent detachment. This spliced ​​insulator design facilitates faster installation of the connecting components.

[0017] Furthermore, the connecting component is provided with elastic elements at one or both ends in the direction of movement to drive the connecting component to reset. The elastic elements can assist the connecting component in automatically resetting after separation from the adapter connector, preparing for the next normal (without deviation) insertion.

[0018] Furthermore, the set angle is 90°. Setting the included angle to 90° is to accommodate the vast majority of application scenarios.

[0019] The floating connector of the present invention adopts the following technical solution: a floating connector, including a floating socket, comprising:

[0020] case;

[0021] At least one connecting component, the connecting component including a contact and a connecting insulator for fixing the contact, the contact having a first plug-in end and a second plug-in end, the plug-in directions of the first plug-in end and the second plug-in end forming a set angle, the set angle being greater than 0° and less than 180°;

[0022] The connecting component is floatingly mounted on the housing along the insertion direction of the first insertion end of the contact and is anti-detached from the housing; the connecting insulator includes a housing mating section, and the width of the mating portion on the housing that mates with the housing mating section in the insertion direction of the first insertion end is greater than the width of the housing mating section, providing conditions for the aforementioned floating of the connecting component.

[0023] Furthermore, the connecting component is equipped with a sliding pad.

[0024] Furthermore, the connecting component also includes a connecting insulator, the contact is fixed to the connecting insulator, and one side of the sliding pad mates with the connecting insulator.

[0025] Furthermore, the connecting component is provided with a guide and positioning component for engaging with the adapter connector.

[0026] Furthermore, a supporting insulator is assembled in the housing, and the connecting component is installed in the supporting insulator.

[0027] Furthermore, the supporting insulator is a modular, spliced ​​structure, and after its various parts are spliced ​​and fixed, the connecting components are confined within the shell to prevent them from detaching.

[0028] Furthermore, the connecting component is provided with elastic elements at one or both ends in the direction of movement to drive the connecting component to reset.

[0029] Furthermore, the set angle is 90°.

[0030] Furthermore, the floating connector also includes a sub-receptacle, with the connecting component floatingly mounted on the housing along the insertion direction of one of the first and second insertion ends. The sub-receptacle is inserted into the other of the first and second insertion ends and has a contact allowance with the connecting component perpendicular to the insertion direction.

[0031] Beneficial effects: The beneficial effects of the floating connector of the present invention are due to the use of the floating socket of the present invention. For details, please refer to the beneficial effects of the floating socket, which will not be repeated here. Attached Figure Description

[0048] The features and performance of this application will be further described in detail below with reference to the embodiments.

[0049] Embodiment 1 of the floating socket of the present invention:

[0050] like Figure 1-5 As shown, the floating socket includes a housing 11, a connecting component 12, and a supporting insulator 13.

[0051] The structure of the housing 11 is as follows Figure 1 , 2 As shown, the housing 11 is cylindrical, and a locking mechanism 14 is provided at the front end of its inner hole. In this embodiment, the locking mechanism 14 is specifically a steel ball locking mechanism. Of course, in other embodiments, the steel ball locking mechanism can be replaced by any other type of locking mechanism. Figure 1As shown, a sealing ring groove is provided on the inner wall of the housing 11, and an interface sealing ring 15 is installed in the sealing ring groove. On the side of the interface sealing ring 15 away from the locking mechanism 14, an interface insulator 17 is also installed in the inner hole of the housing 11 through a snap ring 16.

[0052] The structure of the connecting component 12 is also referred to Figure 1 and Figure 2 It includes a contact 121 and a connecting insulator 122 that fixes the contact 121. In this embodiment, there are two contacts 121, and their structure is as follows: Figure 3As shown, each of the two contacts 121 has a first insertion end 1211 and a second insertion end 1212. The insertion directions of the first insertion end 1211 and the second insertion end 1212 are at a 90° angle, which can be used for connection between two components (such as a printed circuit board) perpendicular to the insertion direction. Of course, in other embodiments, the number of contacts 121 can be arbitrarily set as needed, for example, it can be one or more, and the included angle between the insertion directions of the first insertion end 1211 and the second insertion end 1212 of the contact 121 can also be arbitrarily set as needed, for example, it can be in the range of greater than 0° and less than 180°. The connecting insulator can, on the one hand, avoid the contact directly rubbing against the sliding mating body and thus avoid wear, and on the other hand, when there are multiple contacts, it can realize the integration of multiple contacts and ensure that each contact is synchronized. The connecting insulator 122 is mounted on the housing 11 and can float relative to the housing 11 along the insertion direction of the first insertion end 1211. It includes a housing mating section 1221, a middle section 1222, and a tail section 1223 arranged sequentially from one end near the locking mechanism 14 to the other. The housing mating section 1221 mates with the inner hole of the housing 11, and an inner sealing ring 18 is provided between it and the housing 11. The width of the portion of the housing 11 that mates with the housing mating section 1221 in the insertion direction of the first insertion end 1211 is greater than the width of the housing mating section 1221, thus providing the conditions for the aforementioned floating of the connecting component 12. The middle section 1222 has a rectangular cross-section, and the tail section 1223 is flat. A guide sleeve 1224 is provided on the tail section 1223, extending along the insertion direction of the second insertion end 1212, and can guide and engage with the adapter connector 24. Of course, in other embodiments, the guide sleeve 1224 can also be replaced by a guide rod or the like. The interface insulator 17 has a through hole corresponding to the first insertion end 1211 of the contact member 121. The through hole is rectangular and its shape is adapted to the first insertion end 1211 of the contact member 121. An enlarged section is provided at the rear end of the through hole to cooperate with the forward-protruding protrusion 1225 provided on the connecting insulator 122. In addition, in order to assist the connecting member 12 in centering in the floating direction, a first elastic member 21 is provided between the interface insulator 17 and the connecting insulator 122 of the connecting member 12. The first elastic member 21 is shaped like a screw, specifically an elastic block. Positioning grooves that cooperate with the first elastic member 21 are provided on both the interface insulator 17 and the connecting insulator 122.

[0053] The supporting insulator 13 is installed on the housing 11, with one end near the first insertion end 1211 of the contact member 121 located inside the housing 11. The housing 11 has an inwardly protruding inner edge, and the supporting insulator 13 has an outwardly protruding outer edge. The cooperation between the inner and outer protruding edges prevents the supporting insulator 13 from dislodging from the housing 11 in the opposite direction of insertion of the first insertion end 1211. An inner cavity is provided inside the supporting insulator 13, and the portion of the connecting member 12 located outside the housing 11 is installed in the inner cavity of the supporting insulator 13. To position the connecting member 12, corresponding sections that cooperate with the middle section 1222 and the tail section 1223 of the connecting member 12 are respectively provided in the inner cavity of the supporting insulator 13 to limit the connection member 12 in the insertion direction of the second insertion end 1212. To reduce friction at the mating point with the supporting insulator 13, grooves are provided on both sides of the connecting insulator 122 to reduce the contact area. A sliding pad 20 is also provided between the connecting insulator 122 and the supporting insulator 13. The inner cavity of the supporting insulator 13 has a slot 131 at one end near the second insertion end 1212, which guides and mates with the corresponding end of the connecting insulator 122. A second elastic element, which mates with the connecting insulator 122 of the connecting component 12, is also provided in this slot 131. The structure and installation method of the second elastic element are the same as those of the first elastic element 21, and will not be described in detail here. To facilitate the installation of the connecting component 12, the supporting insulator 13 adopts a split structure, specifically a split structure in this embodiment, and is then fixed by fasteners 22. For aesthetic purposes and to avoid other problems caused by exposed fasteners 22, a baffle 23 is also provided on the outer end of the fastener 22 on the supporting insulator 13. The baffle 23 is installed by embedding.

[0054] When assembling the floating socket of this embodiment, the two parts of the supporting insulator 13 can be joined and fixed first. While joining, the sliding pad 20, connecting component 12, and second elastic element are installed on the supporting insulator 13. Then, the components consisting of the above-mentioned parts, the first elastic element 21, the interface insulator 17, the retaining ring 16, and the interface sealing ring 15 are sequentially arranged from front to back (within the first part). Figure 1 To assemble this floating socket, insert the housing 11 from the left side (front) and then install the dust cover 111.

[0055] like Figure 4 , 5As shown, when the adapter connector 24 is plugged in, the long pin 2611 on the adapter connector 24 is inserted into the guide sleeve 1224 of the connecting component 12, thereby driving the connecting component 12 to move, thus realizing floating installation in the Z direction. Floating installation in the Y direction is achieved by connecting the contact length of the conductive parts through a reasonable design. In the X direction, the inner hole of the guide sleeve 1224 is larger than the long pin 2611 in this direction, and the cavity on the supporting insulator 13 that mates with the plug terminal of the adapter socket is larger than the plug terminal of the adapter socket in this direction, thereby compensating for the offset and thus constituting the floating installation of the entire connection system in the XYZ directions.

[0056] Embodiment 2 of the floating socket of the present invention:

[0057] like Figure 6-7 As shown, the difference between this embodiment and the first embodiment of the floating socket is only that: in this embodiment, the supporting insulator 13 adopts a partially separated split structure, and only the part that blocks the connection component 12 from entering is set separately to form a pressure cover 25, and the pressure cover 25 is engaged with the other parts of the supporting insulator 13.

[0058] Embodiment 1 of the floating connector of the present invention:

[0059] like Figure 1-3 and Figure 6-12 As shown, the floating connector includes a floating socket with the structure of Embodiment 1 of the above-described floating socket and a matching sub-socket 26. The sub-socket 26 includes a base 261 and a connector 262 mounted on the base 261. A long pin 2611 is provided on the base 261 to cooperate with the guide sleeve 1224 on the floating socket. The cross-section of the long pin 2611 is rectangular, and its size in the X direction is smaller than the size of the guide sleeve 1224. The connector 262 is provided with an insulating sleeve 263. The insulating sleeve 263 has openings at both ends in the X direction, and the cavity formed on the supporting insulator 13 on the floating socket has a size in the X direction larger than the width of the insulating sleeve 263, thereby allowing the sub-socket 26 to be inserted with a deviation in the X direction relative to the floating socket. In the Z direction, when there is a deviation between the sub-socket 26 and the second connection end of the floating socket, it can be straightened by the cooperation of the long pin 2611 and the guide sleeve 1224. In the Y direction, a contact overtravel is provided between the connector 262 and the second contact end of the contact member 121, and it is permissible even if there is a certain deviation between the two in the Y direction.

[0060] The connector 262 is designed with a long and short plate structure, with protrusions 2621 on the long and short plates; the side of the connector 262 has a protrusion 2622 that fits and is fixed to the inner cavity of the base 261; the long and short plate structure design ensures that the insertion and extraction force is gentle when mating, the protrusions 2621 ensure better conductivity, and the protrusions 2622 fit with the insulator. The structure is simple and easy to assemble.

[0061] The above description is merely a preferred embodiment of this application and is not intended to limit this application. The scope of patent protection of this application shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of this application shall also be included within the scope of protection of this application.
