Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and in particular to an electrical connector having locking and unlocking functions. Background Technology

[0002] In electrical connectors, maintaining a secure fit between the plug and socket effectively ensures stable connection signals.

[0003] However, conventional electrical connectors in the prior art typically achieve a locking function by forming a locking mechanism between a bent structure (e.g., a hook) of a first locking member soldered to the plug and a slotted structure (e.g., a bayonet) of a second locking member detachably connected to the plug and fixedly connected to the socket. This approach not only allows for a large range of motion of the bent structure within the slotted structure, but also results in a small locking force when the bent structure and the slotted structure lock together. Consequently, the engagement state between the plug and the socket is unstable, leading to unstable connection signals between the plug and the socket.

[0004] Furthermore, traditional electrical connectors in the existing technology do not have an unlocking function after the male and female interlocking is completed by the bending structure and bayonet, which makes it difficult to pull out the plug. Summary of the Invention

[0005] The electrical connector provided by this invention aims to solve at least some of the defects of existing electrical connectors.

[0006] This invention provides an electrical connector. The electrical connector includes: A first locking element, a second locking element, a plug with a housing, and a socket for use with the plug; The first locking member is fixedly connected to the socket, the first locking member is detachably connected to the housing, and the second locking member is fixedly connected to the housing; The first locking member has a pair of bayonets and a pair of elastic arms, and the second locking member has a pair of piercing structures and a pair of mounting holes; The puncture structure has a shape and size adapted to the bayonet, at least a portion of the elastic arm is located within the mounting hole, and the elastic arm is movable within the mounting hole; The mounting hole has a first side and a second side opposite each other in a first direction, and the first direction is the direction of the line connecting the pair of mounting holes; When the elastic arm abuts against the first side, the piercing structure is locked in the bayonet, so that the first locking member and the second locking member form a locking connection. At this time, the external force applied to the plug cannot pull the plug out of the socket. When the elastic arm moves along the first direction toward the direction of the second side, the piercing structure disengages from the bayonet, and at this time the external force applied to the plug can pull the plug out of the socket.

[0007] In some embodiments, the housing includes at least: The fitting part and the cover part are respectively: the fitting part is in the shape of a hollow cylinder and the cover part is in the shape of a flat plate, and the fitting part protrudes from the middle of the cover part; The first locking member is at least partially detachably embedded in the fitting portion, and the second locking member is at least partially welded to the end face of the cover portion opposite to the fitting portion.

[0008] In some embodiments, the plug further includes: A plug body, which is embedded in the housing and has signal terminals inside; A cable, one end of which is connected to the plug body and communicates with the signal terminal, and the other end of which extends in a second direction away from the plug body; The second direction, the first direction, and the axial direction of the fitting portion are orthogonal to each other.

[0009] In some embodiments, the socket includes: The base and the signal pin adapted to the signal terminal, the base being fixedly connected to the first locking member, and the signal pin protruding from the middle position of the base; When the plug is inserted into the socket in a third direction, the signal pin can be locked in the signal terminal, at which time the signal pin is connected to the signal terminal; Wherein, the third direction is the mating direction of the plug and the socket or the axial direction of the mating part.

[0010] In some embodiments, the first locking member further includes: A connecting part and a pair of locking parts; The connecting portion has a shape and size adapted to the fitting portion, and a pair of locking portions are respectively connected to both sides of the connecting portion to form a symmetrical locking configuration; The locking portions together form a first cavity, and both the fitting portion and the connecting portion are located within the first cavity.

[0011] In some embodiments, the locking portion includes: A connecting arm that protrudes from the connecting portion; A first locking arm protrudes from the end of the connecting arm away from the connecting portion, and the end of the first locking arm opposite to the connecting arm is connected to the elastic arm. The end of the elastic arm opposite to the first locking arm passes through the mounting hole.

[0012] In some embodiments, the connecting portion is detachably fitted into the fitting portion, and the bayonet is formed on the first locking arm; The bayonet extends through the first cavity.

[0013] In some embodiments, the second locking element includes: The substrate and a pair of second locking arms; The substrate is welded to the cover, and a pair of second locking arms protrude from opposite ends of the substrate in the first direction. The substrate and a pair of second locking arms enclose a second cavity, and the first locking arms are located within the second cavity; The piercing structure and the second locking arm are integrally formed.

[0014] In some embodiments, the mounting hole is formed on the substrate and extends through the second cavity.

[0015] In some embodiments, the piercing structure is formed by stamping at least a portion of the second locking arm, and the piercing structure protrudes toward the interior of the second cavity along the first direction.

[0016] At least one beneficial effect of the electrical connector provided in this embodiment of the invention is that: the first locking member of the electrical connector has a pair of bayonets, and the second locking member has a pair of piercing structures. The piercing structures have a shape and size adapted to the bayonets. This design results in a small movement space for the piercing structures within the bayonets, while also providing a large locking force when the piercing structures and bayonets interlock, thereby firmly maintaining the mating state between the plug and the socket, and effectively maintaining the stability of the connection signal. The electrical connector incorporates a flexible arm design. After the piercing structures and bayonets form a male-female interlock, the user can press the flexible arm, thereby forcing the pair of flexible arms to move closer together in a first direction, allowing the piercing structures to disengage from the bayonets. At this time, the plug can be easily pulled out of the socket to meet the insertion and removal requirements of the electrical connector. Attached Figure Description

[0020] The present invention will now be described in detail with reference to specific embodiments. It should be emphasized that the following description is merely exemplary and is not intended to limit the scope and application of the present invention.

[0021] It should be noted that, unless otherwise expressly specified and limited, the terms “X direction”, “Y direction”, “Z direction”, “first direction”, “second direction”, “third direction”, “internal”, “axial”, etc., used in this specification indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," and "third" may explicitly or implicitly include one or more of those features. "A plurality" or "several" means two or more. In addition, "and / or" includes any and all combinations of one or more of the related listed items. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0022] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] In this embodiment, the specific implementation of the "electrical connector" is not limited, and those skilled in the art can selectively use any suitable implementation method according to actual needs.

[0024] In the following description, such as Figures 1-9As shown, the following situation exists: the first direction, the protruding direction of the connecting arm 131, the thickness direction of the first locking arm 132, the thickness direction of the second locking arm 22, or the connecting direction of a pair of mounting holes 211 are defined as the X direction; the second direction or the axial direction of the cable 33 is defined as the Y direction; and the third direction, the mating direction of the plug 30 and the socket 40, the axial direction of the mating part 311, the axial direction of the connecting part 12, the thickness direction of the cover part 312, the thickness direction of the substrate 21, the thickness direction of the base 41, the thickness direction of the connecting arm, the extension direction of the first locking arm 132, or the extension direction of the second locking arm 22 are defined as the Z direction for explanation; wherein, the X direction, the Y direction, and the Z direction are orthogonal to each other.

[0025] It should be noted that the electrical connector 100 can be an RF (Radio Frequency) connector, and the cable 33 is the signal transmission medium of the electrical connector 100.

[0026] Understandably, the plug 30 engages with the socket 40, which serves as the object connector, thereby electrically connecting the cable 33 to the circuitry of the printed circuit board or substrate.

[0027] Please see Figures 1-9 The electrical connector 100 includes: a first locking member 10, a second locking member 20, a plug 30 having a housing 31, and a socket 40 for use with the plug 30.

[0028] The materials used to make the first locking member 10 include, but are not limited to, stainless steel, while the materials used to make the second locking member 20 include, but are not limited to, copper. This gives the first locking member 10 and the second locking member 20 sufficient structural strength after they are interlocked and locked together.

[0029] The first locking member 10 is fixedly connected to the socket 40, the first locking member 10 is detachably connected to the housing 31, and the second locking member 20 is fixedly connected to the housing 31.

[0030] The first locking member 10 has a pair of bayonets 1321 and a pair of elastic arms 11, and the second locking member 20 has a pair of piercing structures 221 and a pair of mounting holes 211.

[0031] The piercing structure 221 has a shape and size that are compatible with the bayonet 1321. This design allows the piercing structure 221 to have only a small space to move within the bayonet 1321, which in turn allows the piercing structure 221 to have a large locking force after it is locked with the bayonet 1321, thereby firmly maintaining the mating state between the plug 30 and the socket 40 and effectively maintaining the stability of the connection signal.

[0032] At least a portion of the elastic arm 11 is located within the mounting hole 211, and the elastic arm 11 is movable within the mounting hole 211.

[0033] The mounting hole 211 has a first side 2111 and a second side 2112 opposite each other in the X direction.

[0034] When the elastic arm 11 abuts against the first side 2111, the piercing structure 221 is locked in the bayonet 1321 so that the first locking member 10 and the second locking member 20 form a locking connection. At this time, the external force applied to the plug 30 cannot pull the plug 30 out of the socket 40. This design realizes the locking function of the plug 30 and the socket 40.

[0035] When the elastic arm 11 moves in the X direction toward the second side 2112, the piercing structure 221 disengages from the bayonet 1321. At this time, the external force applied to the plug 30 can pull the plug 30 out of the socket 40. Therefore, after the piercing structure 221 and the bayonet 1321 form a male-female interlock, the user can press the elastic arm 11, thereby forcing the pair of elastic arms 11 to move closer together in the X direction, so that the piercing structure 221 can disengage from the bayonet 1321. At this time, the plug 30 can be easily pulled out of the socket 40 to meet the plugging and unplugging requirements of the electrical connector 100.

[0036] Because the puncture structure 221 has elastic deformation capability and good durability, after the puncture structure 221 and the bayonet 1321 form a male-female interlocking lock, the first locking member 10 and the second locking member 20 are easy to disassemble, which is beneficial to the multiple insertion and removal requirements of the plug 30.

[0037] It should be noted that the elastic arm 11 has elastic deformation capability and can provide elastic force to limit the pair of elastic arms 11 from moving closer together.

[0038] When the user presses the elastic arm 11, the pressing force acting on the elastic arm 11 can overcome the elastic force mentioned above, thereby forcing the pair of elastic arms 11 to come closer together, so that the piercing structure 221 and the latch 1321 are disengaged. At this time, the user can apply external force to the plug 30 to pull the plug 30 out of the socket 40.

[0039] When the user releases the elastic arm 11, the aforementioned elastic force can drive the pair of elastic arms 11 to move away from each other in the X direction until the elastic arm 11 abuts against the first side 2111. At this time, the plug 30 cannot be pulled out of the socket 40, so that the plug 30 and the socket 40 form a stable and reliable connection.

[0040] In this embodiment, the projection of the bayonet 1321 on the surface of the first locking arm 132 is rectangular, the projection of the mounting hole 211 on the surface of the substrate 21 is also rectangular, and the projection of the piercing structure 221 on the surface of the second locking arm 22 is also rectangular.

[0041] The piercing structure 221 has two opposite sides that are inclined in the Y direction, and the inclined surfaces facilitate the piercing structure 221 to enter or leave the bayonet 1321.

[0042] It should be noted that, such as Figures 10-12 As shown, a conventional electrical connector has a socket locking member 200 and a plug locking member 300. The socket locking member 200 includes a conventional connecting portion 2001 and a pair of conventional locking portions, which are composed of a conventional connecting arm 2002 and a first conventional locking arm 2003. The plug locking member 300 includes a conventional base plate 3001 and a pair of second conventional locking arms 3002.

[0043] Understandably, a pair of conventional locking parts are respectively connected to both sides of the conventional connection part 2001 to form a symmetrical locking configuration, and a pair of second conventional locking arms 3002 protrude from the opposite side edges of the conventional substrate 3001.

[0044] The conventional connecting arm 2002 protrudes from the conventional connecting part 2001, and the first conventional locking arm 2003 protrudes from the end of the conventional connecting arm 2002 away from the conventional connecting part 2001. The conventional connecting arm 2002 and the first conventional locking arm 2003 are connected by an arc-shaped bend, and the first conventional locking arm 2003 is provided with a through conventional bayonet 2004.

[0045] In addition, each end of the second conventional locking arm 3002 away from the conventional base plate 3001 is provided with a hook 3003. The hook 3003 is a bent structure and protrudes into the plug locking member 300.

[0046] Furthermore, the projection of the conventional bayonet 2004 onto the surface of the first conventional locking arm 2003 has a first area, and the projection of the hook 3003 onto the surface of the second conventional locking arm 3002 has a second area, and the second area is smaller than the first area. This indicates that the hook 3003 has a larger range of motion after it is engaged with the conventional bayonet 2004.

[0047] When the latch 3003 is engaged within the conventional latch 2004, the socket locking member 200 and the plug locking member 300 form a locking connection, thereby realizing the locking function of the conventional electrical connector.

[0048] Because the hook 3003 has a large range of motion within the conventional bayonet 2004, and because the hook 3003 and the conventional bayonet 2004 have a small locking force after being interlocked, the mating state between the conventional plug and the conventional socket in the conventional electrical connector is unstable, which in turn causes the connection signal between the conventional plug and the conventional socket to be unstable.

[0049] Please see Figures 1-12Compared with traditional electrical connectors, the first locking member 10 of the electrical connector 100 applied to the socket 40 is supplemented with an elastic arm 11 that can realize the unlocking function. The second locking member 20 of the electrical connector 100 applied to the plug is supplemented with a mounting hole 211 that can be adapted to the elastic arm 11. At the same time, the electrical connector 100 uses a piercing structure 221 to replace the hook 3003, and the electrical connector 100 can realize the unlocking function of the electrical connector 100 by pressing the elastic arm 11.

[0050] In summary, traditional electrical connectors do not have an unlocking function after the male and female interlocking is completed by the hook 3003 and the traditional bayonet 2004, which makes it difficult to unplug the traditional plug.

[0051] In some embodiments, such as Figures 1-9 As shown, the housing 31 includes at least: a fitting portion 311 and a cover portion 312.

[0052] The fitting part 311 is in the shape of a hollow cylinder, the cover part 312 is in the shape of a flat plate, and the fitting part 311 protrudes from the middle position of the cover part 312.

[0053] The first locking member 10 is at least partially detachably embedded in the fitting portion 311, and the second locking member 20 is at least partially welded to the end face of the cover portion 312 opposite to the fitting portion 311.

[0054] In some embodiments, such as Figures 1-9 As shown, the plug 30 also includes a plug body 32 and a cable 33.

[0055] The plug body 32 is embedded in the housing 31, and the plug body 32 is provided with a signal terminal 321.

[0056] One end of the cable 33 is connected to the plug body 32 and communicates with the signal terminal 321, and the other end of the cable 33 extends in the Y direction away from the plug body 32.

[0057] In some embodiments, such as Figures 1-9 As shown, the socket 40 includes a base 41 and a signal pin 42 adapted to the signal terminal 321.

[0058] The base 41 is fixedly connected to the first locking member 10, and the signal pin 42 protrudes from the middle position of the base 41.

[0059] When the plug 30 is inserted into the socket 40 in the Z direction, the signal pin 42 can be locked in the signal terminal 321, and at this time the signal pin 42 is connected to the signal terminal 321.

[0060] In some embodiments, such as Figures 1-9 As shown, the first locking member 10 also includes a connecting part 12 and a pair of locking parts.

[0061] The connecting portion 12 has a shape and size that are adapted to the fitting portion 311, and a pair of locking portions are respectively connected to both sides of the connecting portion 12 to form a symmetrical locking configuration.

[0062] A pair of locking parts enclose and form a first cavity 101, and both the fitting part 311 and the connecting part 12 are located inside the first cavity 101.

[0063] It is understandable that the first locking element 10 and the socket 40 adopt an integral molding design to form an integral molding structure, which effectively solves the technical problem of insufficient strength of the socket 40 in the prior art.

[0064] It should be noted that the one-piece molding structure is manufactured into a seamless integral metal part by means of processes such as mold pressing or machining, which involves molding a pair of elastic arms 11, connecting parts 12 and a pair of locking parts (including connecting arms 131 and first locking arms 132). The one-piece molding structure eliminates the weak connection points that exist in the traditional split structure and improves the overall strength and rigidity of the first locking part 10.

[0065] In some embodiments, such as Figures 1-9 As shown, the locking part includes a connecting arm 131 and a first locking arm 132.

[0066] The connecting arm 131 protrudes from the connecting part 12, the first locking arm 132 protrudes from the end of the connecting arm 131 away from the connecting part 12, and the end of the first locking arm 132 away from the connecting arm 131 is connected to the elastic arm 11.

[0067] The end of the elastic arm 11 that is away from the first locking arm 132 passes through the mounting hole 211.

[0068] In this embodiment, the connecting arm 131 and the first locking arm 132 are connected by an arc-shaped bend, which enables the connecting arm 131 and the first locking arm 132 to have good elastic deformation capability, so as to increase the locking force required after the first locking member 10 and the second locking member 20 form a locking connection, thereby increasing the connection stability between the plug 30 and the socket 40.

[0069] In some embodiments, such as Figures 1-9 As shown, the connecting part 12 is detachably embedded in the fitting part 311, and the bayonet 1321 is formed on the first locking arm 132.

[0070] Among them, the bayonet 1321 is connected to the first cavity 101.

[0071] Since the connecting part 12 can connect a pair of locking parts into an integral structure, the external force acting on the plug 30 can be distributed to the first locking arm 132 of the pair of locking parts, avoiding the problem of excessive local stress caused by the force being concentrated on a single locking arm; in addition, the integrally molded connecting part 12 has a sufficient cross-sectional area and a reasonable geometry, and the connecting part 12 can effectively transmit stress without breaking or plastic deformation; the stress transmission effect of the connecting part 12 makes the first locking member 10 exhibit excellent overall performance when subjected to external force, effectively preventing the housing 31 of the plug 30 from yielding and deformation, and ensuring the integrity of the connection between the electrical connector 100 and the printed circuit board or substrate.

[0072] In some embodiments, such as Figures 1-9 As shown, the second locking member 20 includes a base plate 21 and a pair of second locking arms 22.

[0073] The substrate 21 is soldered onto the cover portion 312, and a pair of second locking arms 22 protrude from opposite ends of the substrate 21 in the X direction.

[0074] The substrate 21 and a pair of second locking arms 22 enclose a second cavity 201, and the first locking arm 132 is located inside the second cavity 201.

[0075] The puncture structure 221 and the second locking arm 22 are integrally formed.

[0076] In some embodiments, such as Figures 1-9 As shown, mounting hole 211 is formed on substrate 21 and extends through second cavity 201.

[0077] In some embodiments, such as Figures 1-9 As shown, the puncture structure 221 is formed by stamping at least a portion of the second locking arm 22, and the puncture structure 221 protrudes into the interior of the second cavity 201 along the X direction.

[0078] Please see Figures 1-9 The locking process of the electrical connector 100 is described in detail below: First, the first locking member 10 is fixedly connected to the socket 40; second, the base plate 21 of the second locking member 20 is soldered to the surface of the cover portion 312 of the housing 31 of the plug 30; then, the elastic arm 11 of the first locking member 10 is inserted into and passes through the mounting hole 211 on the base plate 21 of the second locking member 20; finally, the fitting portion 311 of the housing 31 of the plug 30 is fitted into the connecting portion 12 of the first locking member 10, at which point the piercing structure 221 can form a male-female interlock with the bayonet 1321 to achieve a locking connection between the first locking member 10 and the second locking member 20, thereby making the plug 30 firmly locked on the socket 40.

[0079] like Figures 1-9As shown, the unlocking process of the electrical connector 100 is described in detail: First, press the elastic arm 11 so that a pair of elastic arms come together in the X direction, at which point the piercing structure 221 disengages from the bayonet 1321; second, apply external force to the plug 30 to overcome the insertion and extraction force between the mating part 311 and the connecting part 12; finally, lift the plug 30 in the Z direction so that the plug 30 is pulled out of the socket 40.

[0080] In summary, the electrical connector provided in this embodiment of the invention has a first locking member with a pair of bayonets and a second locking member with a pair of piercing structures. The piercing structures have a shape and size adapted to the bayonets. This design minimizes the movement space of the piercing structures within the bayonets while simultaneously providing a large locking force when the piercing structures and bayonets interlock, thus firmly maintaining the mating state between the plug and socket and effectively ensuring stable connection signals. The connector incorporates a flexible arm design. After the piercing structures and bayonets form a male-female interlock, the user can press the flexible arm, forcing the pair of flexible arms to move closer together in a first direction. This allows the piercing structures to disengage from the bayonets, enabling the plug to be easily removed from the socket, thus satisfying the insertion and removal requirements of the electrical connector.

[0081] The above description, in conjunction with specific / preferred embodiments, provides a further detailed explanation of the present invention, but it should not be construed as limiting the specific implementation of the invention to these descriptions. Those skilled in the art will recognize that various modifications and improvements can be made without departing from the concept of the present invention, and all such modifications and improvements fall within the scope of protection of the present invention.
