[0001] This utility model relates to the field of connector technology, and in particular to a floating male connector and electrical connector. Background Technology

[0002] In modern electronic devices, electrical connectors are key components for achieving circuit connections. Traditional electrical connectors typically consist of a male and a female connector, achieving electrical connection through mating. However, in certain applications, such as when the female connector's mounting space is confined or there are certain alignment errors, the rigid structure of traditional fixed male connectors makes smooth mating and reliable connection difficult. In such cases, a significant positional deviation between the male and female connectors can lead to mating difficulties, or even damage to the connector or connected circuit boards.

[0003] Therefore, users want to allow the male and female connectors to maintain electrical connection while allowing for a certain range of relative displacement during mating, in order to compensate for installation errors and improve the fault tolerance of mating. Utility Model Content

The first end is connected to the frame, the second end is connected to the plug portion on the plug, and the bent portion connects the first end and the second end in an elastic deformation manner.

[0007] With the help of the bending portion, the plug can float freely in three-dimensional space relative to the frame.

[0009] Preferably, the first connection terminal includes a positive pin and a negative pin, which are located on opposite sides of the central axis of the accommodating space.

[0010] Preferably, the plug is provided with a partition for isolating the positive pin and the negative pin.

[0011] Preferably, the ends of the two frame sides are connected by a support beam, and the connection between the two frame sides and the support beam is higher than the support beam, so as to form a stop at both ends of the support beam. A connecting block is provided at each end of the plug, the connecting block is placed flat on the support beam and can slide relative to the support beam, and the stop is used to block the movement of the support beam.

[0012] This utility model also provides a floating electrical connector, which includes a male connector and a female connector. The male connector includes two opposing frames and a plug, with a receiving space formed between the two frames. The plug is located outside the bottom end of the receiving space, and the width of the plug is smaller than the distance between the two frames. The plug includes a connecting part at the top end and a plugging part at the bottom end.

[0013] The accommodating space is provided with a first connection terminal, which includes a first end, a second end, and a bent portion located between the first end and the second end. The first end is connected to the frame, the second end is connected to the plug portion on the plug, and the bent portion connects the first end and the second end in an elastic deformation manner.

[0014] With the help of the bending portion, the plug can float freely in three-dimensional space relative to the frame;

[0015] The connector is provided with a plug-in mating part and a second connecting terminal. The second connecting terminal includes a third end and a fourth end. The third end is located on the plug-in mating part, and the fourth end is used to connect to an external circuit.

[0029] To explain in detail the technical content, structural features, objectives and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0030] This embodiment discloses a floating electrical connector for electrically connecting two electrical devices, such as... Figure 1 and Figure 2 The connector includes a male connector 1 and a female connector 2. By introducing a floating male connector 1 that works in conjunction with a compatible female connector 2, this connector solves the problem of excessively high installation accuracy requirements in existing connectors.

[0031] Specifically, such as Figures 2 to 6 The male connector 1 includes two opposing frame frames 10 and a plug 11. A receiving space 100 is formed between the two frame frames 10. The plug 11 is located outside the bottom end of the receiving space 100, and the width of the plug 11 is smaller than the distance between the two frame frames 10. That is, the projection surface of the two frame frames 10 can completely cover the projection surface of the plug 11. The plug 11 includes a connecting portion 110 at the top end and a plugging portion 111 at the bottom end.

[0032] A first connection terminal 12 is provided within the accommodating space 100. The first connection terminal 12 includes a first end 120, a second end 121, and a bent portion 122 located between the first end 120 and the second end 121. The first end 120 is connected to the frame 10, and the second end 121 is connected to the plug portion 111 on the plug 11.

[0033] The bend 122 connects the first end 120 and the second end 121 in an elastic deformation manner. With the help of the bend 122, the plug 11 can float freely in three-dimensional space (that is, in the front-back, left-right and up-down dimensions) relative to the frame 10.

[0034] The connector 2 is provided with a plug-in mating part 20 and a second connecting terminal 21. The second connecting terminal 21 includes a third end 210 and a fourth end 211. The third end 210 is located on the plug-in mating part 20, and the fourth end 211 is used to connect to an external circuit.

[0035] The plug-in part 111 and the plug-in mating part 20 can be connected or separated by plugging and unplugging. When the plug-in part 111 and the plug-in mating part 20 are in the connected state, the second end 121 is electrically connected to the third end 210.

[0036] When the plug-in part 111 and the plug-in mating part 20 are fully engaged, the male connector 1 and the female connector 2 establish a mechanical connection. At this time, the second end 121 of the first connecting terminal 12 and the third end 210 of the second connecting terminal 21 make contact through a spring contact, achieving a reliable electrical connection. The floating function of the male connector 1 allows the plug-in part 111 to automatically adjust its position during insertion into the plug-in mating part 20, ensuring smooth mechanical engagement and electrical contact even if the initial alignment is poor.

[0037] In the above scheme, the frame 10 is typically made of insulating material, such as engineering plastic, to provide structural support and insulation protection.

[0038] The receiving space 100 is used to receive a portion of the first connecting terminal 12 and to provide space for the plug 11 to float.

[0039] The plug 11 is also made of insulating material, and its plug portion 111 is the part that makes mechanical and electrical connections with the connecting female socket 2.

[0040] The first connecting terminal 12 and the second connecting terminal 21 are components for transmitting electrical signals, and are made of a conductive and highly elastic metal material.

[0041] The first end 120 is fixed to the frame 10 or the inner surface by means of welding, riveting or injection molding embedding, etc., as an interface or pin for connection with external circuits.

[0042] The second end 121 is fixed to the top surface of the plug part 111 by means of welding, riveting or crimping, and serves as the part that contacts the terminal of the connecting female 2.

[0043] The bending portion 122 is a structural part of the first connecting terminal 12 that has the ability to elastically deform. Through its own bending or torsional deformation, it allows the second end 121 (and the plug 11 fixed thereto) to move within a certain range relative to the first end 120 (and the frame 10 fixed thereto), thereby compensating for alignment deviations during the mating process.

[0044] The electrical connector in this embodiment significantly improves the fault tolerance and reliability of the overall connection system through the floating design of the male connector. In the above solution, since the plug 11 of the male connector 1 can float within a certain range, the installation accuracy requirements of the male connector 1 and the female connector 2 during the mating process are greatly reduced. For example, even if there is a ±mm deviation in the installation position of the male connector 1 and the female connector 2, the floating capability of the plug 11 can compensate for this deviation, ensuring smooth mating and reliable electrical connection. This greatly simplifies the equipment assembly process, reduces the requirements for processing and installation tolerances, and improves production efficiency and product yield. In narrow or difficult-to-operate environments, the floating function makes mating and unmating operations more convenient, reducing connection failures or terminal damage caused by alignment difficulties. At the same time, the floating connection reduces the stress on the terminals during mating and unmating, extending the service life of the terminals.

[0045] On the other hand, the bending portion 122 includes a first bending segment 122a and a second bending segment 122b, the first bending segment 122a arching upward and the second bending segment 122b arching downward.

[0046] In this embodiment, a structure consisting of two bending segments in opposite directions is adopted to obtain a more stable and reliable elastic floating capability.

[0047] This combined upward and downward arching bending structure utilizes the bending characteristics of the material in different directions. This allows the entire bent section 122 to achieve greater elastic displacement through the coordinated deformation of the two bending segments when subjected to a force perpendicular to the plug 11, ensuring a rapid return to its original shape after the external force is removed, thus avoiding permanent deformation. This structural design helps achieve a large floating range within a small space while maintaining the contact stability and reliability of the terminals.

[0048] More specifically, the upward-arched bend is directed towards the top of the receiving space 100 or the edge 10, while the downward-arched bend is directed towards the plug 11 or the bottom of the receiving space 100. The two bends form a reverse bend point at their midpoint. This structure allows both bends to bend simultaneously when the bend 122 is subjected to a vertical force, thus allowing displacement of the second end 121 and the plug 11 in the vertical direction. For example, when the plug 11 needs to float upwards, the upward-arched bend will bend further upwards, and the downward-arched bend will stretch upwards or bend slightly in the opposite direction; when the plug 11 needs to float downwards, the upward-arched bend will bend downwards, and the downward-arched bend will bend further downwards. This coordinated deformation mechanism provides a smoother and more controllable elastic response.

[0049] In the above embodiments, the bending radius, length, and width of the two bending segments can be adjusted according to the desired floating range and elastic force. For example, increasing the length of the bending segment or decreasing the material thickness can increase the floating range, but may decrease the elastic force. Decreasing the length of the bending segment or increasing the material thickness can increase the elastic force, but may decrease the floating range.

[0050] On the other hand, such as Figure 3 The first connection terminal 12 includes a positive pin 12a and a negative pin 12b, which are located on opposite sides of the central axis of the accommodating space 100. In use, the positive pin 12a is connected to the positive power supply of an external device, and the negative pin 12b is connected to the negative power supply of the device to establish a power path.

[0051] Furthermore, the plug 11 is provided with a partition 16 for isolating the positive pin 12a and the negative pin 12b.

[0052] In this embodiment, the positive pin 12a and the negative pin 12b are respectively arranged on both sides of the central axis of the accommodating space 100, which effectively increases the electrical clearance and creepage distance between the positive and negative poles and improves the electrical safety performance of the connector.

[0053] The partition 16 is made of insulating material and physically separates the positive pin 12a from the negative pin 12b, effectively increasing the creepage distance and space distance between them. It can maintain good insulation performance even in harsh environments, further improving the safety and reliability of the connector.

[0054] On the other hand, the ends of the two side frames 10 are connected by a support beam 13. The connection between the two side frames 10 and the support beam 13 is higher than the support beam 13, so that a stop part 14 is formed at both ends of the support beam 13. A connecting block 15 is provided at both ends of the plug 11. The connecting block 15 is placed flat on the support beam 13 and can slide relative to the support beam 13. The stop part 14 is used to block the movement of the support beam 13.

[0055] This embodiment further provides a functional structure for enabling the plug 11 to float and be limited in the horizontal direction. By providing a support beam 13 at the end of the frame 10 and connecting blocks 15 at both ends of the plug 11, the connecting blocks 15 can slide on the support beam 13, thereby allowing the plug 11 to move horizontally relative to the frame 10. The stop portions 14 at both ends of the support beam 13 are used to limit the horizontal floating range of the plug 11, preventing excessive movement that could cause structural damage or detachment.

[0056] On the other hand, a slot 111 forming a plug-in portion 111 is provided at the bottom of the plug 11, the second end 121 of the first connecting terminal 12 is attached to the side wall of the slot 111, and a plug block 20 forming a plug-in mating portion 20 is provided on the connecting female 2, and the third end 210 of the second connecting terminal 21 is attached to the side wall of the plug block 20.

[0057] In this embodiment, a slot 111 is formed at the bottom end of the plug 11 to form a plug portion 111. The slot 111 is one or more groove-shaped structures formed by the recess at the bottom end of the plug 11, used to receive the plug block 20 of the connecting socket 2.

[0058] The second end 121 of the first connecting terminal 12 is attached to the side wall of the slot 111. This means that the second end 121 is arranged along the side wall surface of the slot 111 and is usually fixed to its surface by means of welding or crimping.

[0059] The insert 20 is a protruding structure on the connector 2 that mates with the slot 111. Its shape and size are adapted to the slot 111, and there can be one or more inserts. The third end 210 of the second connecting terminal 21 is attached to the side wall of the insert 20. This means that the third end 210 is arranged along the side wall surface of the insert 20, serving as a contact element that contacts the second end 121 of the first connecting terminal 12. When the slot 111 of the plug 11 is inserted into the insert 20 of the connector 2, the side wall of the slot 111 and the side wall of the insert 20 slide against each other, achieving a mechanical connection.

[0060] At the same time, the second end 121 of the first connecting terminal 12 attached to the side wall of the slot 111 and the third end 210 of the second connecting terminal 21 attached to the side wall of the insert 20 are in contact with each other (e.g., Figure 5 To establish an electrical connection, for example, the third end 210 can be designed with a spring-loaded foot that contacts the second end 121 during insertion and generates a certain contact force to ensure a reliable connection.

[0061] This embodiment employs a mating structure of slot 111 and plug 20, with the terminals attached to the sidewall, offering advantages such as simple structure, ease of manufacturing, and assembly. The mating of slot 111 and plug 20 provides excellent guidance, enabling the floating male connector 1 to find the correct position more smoothly during insertion. Even with some initial alignment deviation, automatic alignment can be achieved through the bevels or chamfers of slot 111 and plug 20.

[0062] Furthermore, attaching the terminals to the sidewalls allows for full utilization of the structure of the slot 111 and the plug 20 for support, improving the stability of the terminals during insertion and removal and reducing the risk of bending or damage. This structure also ensures that the terminal contact area is located inside the slot 111 and the plug 20, protected by the structure and less susceptible to external environmental factors (such as dust and moisture), thus improving the reliability of the connection.

[0063] On the other hand, such as Figure 6 and Figure 7 To facilitate precise engagement between the slot 111 and the plug 20, the slot 111 is provided with a locking protrusion 112, and the plug 20 is provided with a locking groove 22 that matches the locking protrusion 112. When the slot 111 and the plug 20 are engaged, the locking protrusion 112 enters the locking groove 22 to achieve a stable and precise connection between the male connector 1 and the female connector 2.

[0064] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the scope of the present utility model application shall still fall within the scope of the present utility model.
