Description

Technical Field

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

[0002] In existing electrical connector technology, the support structure is mostly an independent metal reinforcement or plastic bracket, directly fixed to the bottom or rear end of the connector, and often connected to the shell by simple snap-fit ​​or riveting. When the connector is plugged in or unplugged, the shell is prone to back-and-forth movement due to stress, leading to internal terminal misalignment, poor contact, or solder joint cracking. Furthermore, the connection between the support and the shell is mostly single-point fixed, resulting in weak vibration and impact resistance, low assembly precision, and difficulty in ensuring long-term reliability. Although some structures have limiting bosses or baffles, they are mostly limited to fixing in a single direction and cannot achieve stable multi-directional cooperation between the support and the shell, resulting in insufficient overall structural stability.

[0008] Wherein, the first direction and the second direction are intersecting;

[0009] The bottom wall, the first side wall, and the second side wall are positioned to form a first limiting space, which is used to limit the movement of the insulating shell along the first direction;

[0010] One of the support member and the insulating shell is provided with a positioning part, and the other is provided with a mating part. The mating part is engaged with the positioning part to limit the connection between the insulating shell and the support member.

[0011] In one embodiment, the first limiting portion is a protrusion structure disposed toward the first sidewall along the second direction.

[0012] In one embodiment, the support member further has a second limiting portion, which extends in the opposite direction to the first limiting portion;

[0013] The electrical connector further includes a circuit board disposed on the insulating body, the circuit board abutting against the second limiting portion to limit the movement of the circuit board along the second direction.

[0014] In one embodiment, the second limiting portion is a protrusion structure disposed away from the first sidewall along the second direction.

[0015] In one embodiment, the support member includes a support plate and a support portion, the first limiting portion and the second limiting portion are spaced apart on both sides of the support plate along the first direction, the support portion extends along the second direction and is disposed on the support plate, and the support portion is provided with the positioning portion;

[0016] The insulating housing includes a housing body and a housing support portion. The housing body has a first sidewall and a second sidewall.

[0017] In one embodiment, the positioning part is a mounting opening provided on the support part, and the mating part is a protrusion provided on the outer shell support part.

[0018] In one embodiment, the support portion includes a first support foot and a second support foot, the first support foot and the second support foot being respectively spaced apart on both sides of the support plate along the second direction, and a second limiting space being formed between the first support foot and the second support foot, and the circuit board being at least partially accommodated in the second limiting space.

[0019] In one embodiment, the outer shell support includes a third support foot and a fourth support foot, the third support foot and the first support foot being disposed opposite each other, the fourth support foot and the second support foot being disposed opposite each other, the first support foot and the second support foot each having the positioning part, the third support foot and the fourth support foot each having the mating part, the mating part engaging with the positioning part to limit the connection between the third support foot and the first support foot and the fourth support foot and the second support foot.

[0020] In one embodiment, the outer shell body includes a first shell, a second shell, and a third shell. The first shell is sleeved on the outer periphery of the third shell, and the third shell is sleeved on the outer periphery of the second shell.

[0022] This utility model discloses an electrical connector that achieves stable support and multi-directional limiting of key internal components through precise cooperation between the insulating body, insulating shell, and support member, thereby improving the overall mechanical stability and connection reliability. Specifically, the insulating body extends along a first direction, serving as the basic structure supporting conductive terminals and the circuit board. It is sandwiched between the first and second sidewalls of the insulating shell, ensuring its centered and protected position. The second sidewall has a mounting groove extending along the first direction, formed by a bottom wall and the first and second sidewalls located on either side of the groove opening, creating a complete first limiting space. The support member is connected to the insulating shell and has a first limiting portion extending along a second direction. This first limiting portion partially inserts into the mounting groove, using the first limiting space to constrain its movement in the first direction, preventing axial displacement of the insulating shell due to insertion / extraction forces, vibration, or external impact. Since the first and second directions intersect, the extension characteristic of the first limiting portion in the second direction also allows the support member to provide lateral support, enhancing the rigidity of the overall structure. In addition, a positioning part and a mating part limit fit structure are provided between the support and the insulating shell. The reliable connection is achieved through the interlocking of the two, which not only improves the assembly accuracy, but also effectively prevents the parts from loosening or falling off during use. Through the synergistic effect of multi-directional limit and mechanical locking, the stability and service life of the electrical connector are significantly improved. Attached Figure Description

[0037] This utility model proposes an electrical connector.

[0038] Reference Figures 1 to 7 In this embodiment of the present invention, an electrical connector includes:

[0039] An insulating body 10 is provided extending along a first direction;

[0040] An insulating shell 20 has a first sidewall 21 and a second sidewall 22 disposed opposite to each other. The insulating body 10 is located between the first sidewall 21 and the second sidewall 22. The second sidewall 22 has a mounting groove 221 extending along the first direction. The mounting groove 221 has a groove opening 2211, a bottom wall 2212 disposed opposite to the groove opening 2211, and a first sidewall 2213 and a second sidewall 2214 located on opposite sides of the groove opening 2211. The first sidewall 2213 and the second sidewall 2214 extend along the first direction.

[0041] A support member 30 is connected to the insulating shell 20. The support member 30 has a first limiting part 31 that extends relative to each other along a second direction. The first limiting part 31 is partially accommodated in the mounting groove 221.

[0042] Wherein, the first direction and the second direction are intersecting;

[0043] The bottom wall 2212, the first side wall 2213 and the second side wall 2214 are positioned to form a first limiting space, which is used to limit the movement of the insulating shell 20 along the first direction;

[0044] One of the support member 30 and the insulating shell 20 is provided with a positioning part 32, and the other is provided with a mating part 23. The mating part 23 is matched with the positioning part 32 to limit the connection between the insulating shell 20 and the support member 30.

[0045] This design is a structural design for an electrical connector. Its core lies in the precise fit between the insulating body 10, the insulating shell 20, and the support member 30, achieving stable installation and multi-directional positioning of the connector's internal components, thereby improving the overall structural reliability and anti-interference capability. The insulating body 10 extends along a first direction and serves as the basic structure supporting key functional components such as conductive terminals. It is positioned between the first sidewall 21 and the second sidewall 22 of the insulating shell 20 to ensure its positional stability. The mounting groove 221 (with a slot 2211, a bottom wall 2212, and two sidewalls) on the second sidewall 22 provides an embedding space for the first limiting portion 31 of the support member 30. The support member 30 is connected to the insulating shell 20 and has a first limiting portion 31 extending along a second direction. This first limiting portion 31 is partially accommodated within the mounting groove 221. The first limiting space formed by the bottom wall 2212, the first sidewall 2213, and the second sidewall 2214 restricts the movement of the insulating shell 20 in the first direction, preventing axial displacement due to vibration or insertion / extraction forces. Since the first direction intersects with the second direction (which can be perpendicular), the extension characteristic of the first limiting part 31 in the second direction allows the support member 30 to also support and limit the insulating shell 20 in that direction, thereby achieving coordinated fixation in two orthogonal directions and significantly enhancing structural stability. Furthermore, the first limiting space is provided to achieve precise and stable axial limiting of the insulating shell 20 in the first direction, preventing displacement or loosening along the first direction due to external forces (such as insertion / extraction forces, vibration, or impact) during use. This first limiting space is formed by the bottom wall 2212, the first side wall 2213, and the second side wall 2214 of the mounting groove 221. When the first limiting part 31 of the support member 30 is partially accommodated within this space, the bottom wall 2212 bears the axial thrust or tension, while the side walls restrict lateral displacement, thereby firmly constraining the insulating shell 20 in a predetermined position. This structural design not only improves the connection rigidity between internal components of the electrical connector, but also effectively enhances the overall mechanical stability and fatigue resistance of the structure. It ensures that the positions of critical components such as the insulating body 10 and conductive terminals do not shift under long-term insertion / removal or harsh working environments, thereby guaranteeing the reliability and safety of electrical contact. Furthermore, a positioning and mating structure (including but not limited to snap-fits, bosses, and grooves) is provided between the support member 30 and the insulating shell 20, connecting the positioning part 32 and the mating part 23. This design not only facilitates alignment and connection during assembly but also effectively prevents loosening or separation during use, further enhancing the overall mechanical strength and durability of the connector. Through the combination of a multi-directional limiting structure and a positioning and mating mechanism, this design effectively improves the structural stability and connection reliability of the electrical connector under complex working conditions while ensuring its miniaturization and manufacturability. It is suitable for applications involving high vibration, high precision, or frequent insertion / removal.

[0046] Reference Figures 1 to 7 In this embodiment of the present invention, the first limiting part 31 is a protruding structure disposed toward the first sidewall 21 along the second direction.

[0047] The first limiting part 31 is a protruding structure extending along the second direction toward the first sidewall 21 of the insulating shell 20. The design of the protruding structure allows the first limiting part 31 to be more effectively inserted into and fitted into the mounting groove 221 of the second sidewall 22 of the insulating shell 20, forming a tight fit and thus enhancing the mechanical connection strength between the two. The protruding structure is arranged along the second direction and extends toward the first sidewall 21, with its direction of action opposite to the second sidewall 22 where the mounting groove 221 is located. It can generate a reverse supporting force on the insulating shell 20 in the first direction. When an external load (such as axial tension or vibration) acts on the connector, the protrusion can abut against the bottom wall 2212 or sidewall of the mounting groove 221, preventing the insulating shell 20 from displacing toward the first sidewall 21, thereby effectively limiting movement in the first direction.

[0048] Reference Figures 1 to 7 In this embodiment of the present invention, the support member 30 further has a second limiting part 33, which extends in the opposite direction to the first limiting part 31.

[0049] The electrical connector also includes a circuit board disposed on the insulating body 10. The circuit board abuts against the second limiting portion 33 to limit the movement of the circuit board along the second direction.

[0050] By adding a second limiting part 33 extending in the opposite direction to the first limiting part 31 to the support member 30, and using this second limiting part 33 to abut against the circuit board disposed on the insulating body 10, the circuit board is effectively limited in the second direction. Specifically, the support member 30 not only has a first limiting part 31 extending into the mounting groove 221 of the insulating housing 20 to limit the movement of the insulating housing 20 in the first direction, but also extends a second limiting part 33 in the opposite direction. This structure is usually located on the other side of the support member 30 or in a symmetrical position, forming a bidirectional extending support and limiting layout. When the circuit board is installed on the insulating body 10, its edge or a specific area makes physical contact (abuts) with the second limiting part 33. At this time, the second limiting part 33 acts as a mechanical stop, preventing the circuit board from shifting or deviating in the second direction. This design can effectively prevent the circuit board from loosening, shifting, or even falling off due to vibration, impact, or assembly errors, ensuring that the electrical connection between the circuit board and the internal terminals of the connector remains stable and reliable. Meanwhile, since the first limiting part 31 and the second limiting part 33 are integrated on the same support member 30, the support member 30 can serve as a multifunctional structural component, combining the functions of fixing the outer shell, supporting the overall structure, and positioning the circuit board. This not only simplifies the number of parts and improves space utilization but also enhances the collaborative positioning accuracy between components. In addition, the support member 30 facilitates alignment and limiting during the assembly process, improving production efficiency and product consistency.

[0051] Reference Figures 1 to 7 In this embodiment of the present invention, the second limiting part 33 is a protruding structure disposed away from the first sidewall 21 along the second direction.

[0052] The second limiting part 33 is a protruding structure extending in a second direction away from the first sidewall 21 of the insulating shell 20. The second limiting part 33 protrudes from the support member 30 in the opposite direction to the first limiting part 31 (i.e., the side away from the first sidewall 21), forming a mechanical protrusion with a clear stopping function. When the circuit board is mounted on the insulating body 10, this protruding structure abuts against the edge of the circuit board or a preset limiting area, thereby forming a single-sided or double-sided limiting constraint on the circuit board in the second direction, preventing it from shifting or deviating in that direction. Since the protrusion extends in the second direction, its length and position can be designed to accommodate circuit boards of different sizes or layouts, ensuring the accuracy and reliability of the limiting. Furthermore, designing the second limiting part 33 as a protruding structure not only simplifies the structure and makes it easy to integrally form with the support member 30 (e.g., through metal stamping or injection molding), but also allows for functional integration without adding extra parts, which helps reduce production costs and improve assembly efficiency. Furthermore, this raised structure serves as a guide and positioning element during assembly, ensuring the circuit board is accurately installed and preventing misalignment or interference. More importantly, during the operation of the electrical connector, especially when subjected to vibration, impact, or thermal expansion and contraction, this raised structure provides continuous and stable support, preventing malfunctions such as solder joint cracking, poor contact, or signal interruption caused by loosening of the circuit board, significantly improving the electrical reliability and mechanical durability of the product.

[0053] Reference Figures 1 to 7 In this embodiment of the present invention, the support member 30 includes a support plate 34 and a support portion 35. The first limiting portion 31 and the second limiting portion 33 are spaced apart on both sides of the support plate 34 along the first direction. The support portion 35 extends along the second direction and is disposed on the support plate 34. The support portion 35 is provided with the positioning portion 32.

[0054] The insulating shell 20 includes a shell body 24 and a shell support portion 25. The shell body 24 has a first side wall 21 and a second side wall 22. The shell support portion 25 extends along the second direction and is disposed on the shell body 24. The shell support portion 25 is provided with the mating portion 23.

[0055] Specifically, the support member 30 consists of a support plate 34 and a support portion 35. The support plate 34 serves as a basic load-bearing platform, with a first limiting portion 31 and a second limiting portion 33 respectively provided on both sides along the first direction to form a symmetrical or asymmetrical bidirectional extension structure. The first limiting portion 31 extends into the mounting groove 221 of the second side wall 22 of the insulating shell 20 to restrict the movement of the insulating shell 20 in the first direction. The second limiting portion 33 abuts against the circuit board to limit the position of the circuit board in the second direction, thereby integrating multiple limiting functions on the same support member 30 and improving the structural compactness and functional integration. At the same time, the support portion 35 extends from the support plate 34 along the second direction and is provided with a positioning portion 32 (including but not limited to a boss, a buckle, or a pin) for connection and fixation with the mating portion 23 on the insulating shell 20. Correspondingly, the insulating housing 20 includes a housing body 24 and a housing support 25. The housing body 24 provides space to accommodate the insulating body 10 and the structures of the first and second sidewalls 21 and 22, while the housing support 25 extends from the insulating body 10 along a second direction and is provided with a mating part 23 (including but not limited to grooves, through holes, or slots) that matches the positioning part 32. When the two are assembled, the positioning part 32 and the mating part 23 mutually limit and cooperate with each other, forming a stable mechanical connection. This design not only makes the connection between the support 30 and the insulating housing 20 more robust, but also effectively transmits and disperses external loads, improving the rigidity and vibration resistance of the overall structure.

[0056] Reference Figures 1 to 7 In this embodiment of the present invention, the positioning part 32 is an installation port provided on the support part 35, and the mating part 23 is a protrusion provided on the outer shell support part 25.

[0057] The positioning part 32 is a mounting port on the support part 35 of the support member 30, while the mating part 23 is a protrusion on the outer shell support part 25. The two achieve a limiting fit by the protrusion embedding into the mounting port. The mounting port can be a through hole, blind hole, or U-shaped groove, while the protrusion can be a columnar, hemispherical, or snap-fit ​​structure. When the support member 30 is assembled with the insulating outer shell 20, the protrusion on the outer shell support part 25 aligns with and presses into the mounting port on the support part 35, achieving a fixed connection through elastic deformation or interference fit of the material. This structure not only effectively restricts the relative movement between the support member 30 and the insulating outer shell 20, preventing loosening or detachment, but also possesses good shear and pull-out resistance, significantly improving the mechanical strength and stability of the connection. Simultaneously, because the mating of the mounting port and the protrusion has clear geometric constraints, it can play a guiding and positioning role during assembly, ensuring precise alignment of the support member 30 and the insulating outer shell 20, improving assembly efficiency and product consistency.

[0058] Reference Figures 1 to 7In this embodiment of the present invention, the support portion 35 includes a first support foot 351 and a second support foot 352. The first support foot 351 and the second support foot 352 are respectively disposed on both sides of the support plate 34. A second limiting space is formed between the first support foot 351 and the second support foot 352. The circuit board is at least partially accommodated in the second limiting space.

[0059] The support portion 35 consists of a first support foot 351 and a second support foot 352 respectively disposed on both sides of the support plate 34. These two feet extend along the second direction and are arranged opposite each other, jointly defining a second limiting space for accommodating the circuit board. This design allows the first support foot 351 and the second support foot 352 to not only serve as structural support elements but also to clamp and position the circuit board. When the circuit board is mounted on the insulating body 10, its side or a localized area is guided into the second limiting space formed between the two support feet, thereby achieving bidirectional limiting in the second direction. Specifically, the first support foot 351 restricts the circuit board from moving to one side, and the second support foot 352 restricts its movement to the other side, effectively preventing the circuit board from shifting, shaking, or becoming loose in the second direction. Compared to limiting methods with only one-sided contact, this double-sided clamping structure provides a more stable and precise constraint effect, significantly improving the installation reliability of the circuit board under complex conditions such as vibration, impact, or thermal cycling. Meanwhile, since the first support foot 351 and the second support foot 352 are integrated on both sides of the support plate 34, they can be integrally formed with the support plate 34 (usually manufactured using metal stamping process).

[0060] Reference Figures 1 to 7 In this embodiment of the present invention, the outer shell support portion 25 includes a third support leg 251 and a fourth support leg 252. The third support leg 251 and the first support leg 351 are disposed opposite to each other, and the fourth support leg 252 and the second support leg 352 are disposed opposite to each other. The first support leg 351 and the second support leg 352 are each provided with the positioning portion 32. The third support leg 251 and the fourth support leg 252 are each provided with the mating portion 23. The mating portion 23 is engaged with the positioning portion 32 to limit the connection between the third support leg 251 and the first support leg 351 and the fourth support leg 252 and the second support leg 352.

[0061] The outer shell support 25 includes a third support leg 251 and a fourth support leg 252, which are respectively arranged opposite to the first support leg 351 and the second support leg 352 on the support member 30, forming two sets of symmetrical leg mating structures. Simultaneously, both the first support leg 351 and the second support leg 352 are provided with positioning parts 32 (such as mounting openings), while the third support leg 251 and the fourth support leg 252 are correspondingly provided with mating parts 23 (such as protrusions). Through the limiting cooperation of the two sets of positioning parts 32 and mating parts 23, a double connection and fixation is achieved between the third support leg 251 and the first support leg 351, and between the fourth support leg 252 and the second support leg 352. This design enables the support member 30 and the insulating outer shell 20 to form a symmetrical structure with synchronous connection on both sides, which not only significantly enhances the connection strength and overall rigidity between the two, but also effectively balances the assembly stress, avoiding structural off-center loading or torsional deformation caused by unilateral connection. Since the first support foot 351 and the second support foot 352 are located on both sides of the support plate 34, and the third support foot 251 and the fourth support foot 252 are located on both sides of the outer shell support part 25, and all extend along the second direction and are precisely aligned, their connection forms a stable spatial frame structure. This structure can better resist external vibration, impact, and the torque and shear forces generated during insertion and removal, thereby improving the mechanical durability and long-term reliability of the electrical connector. In addition, the simultaneous arrangement of the positioning part 32 and the mating part 23 on both sides improves the guidance and alignment during assembly, ensuring that the support part 30 and the insulating shell 20 are accurately and smoothly connected, reducing the risk of misalignment or poor assembly, and facilitating automated and efficient production. More importantly, this symmetrical double connection structure works in conjunction with the second limiting space formed by the first support foot 351 and the second support foot 352 to fix the circuit board while also firmly locking the support frame around the circuit board, further ensuring the positional stability of the circuit board in the entire connector structure.

[0062] Reference Figures 1 to 7 In this embodiment of the present invention, the outer shell body 24 includes a first shell 241, a second shell 242, and a third shell 243. The first shell 241 is sleeved on the outer periphery of the third shell 243, and the third shell 243 is sleeved on the outer periphery of the second shell 242. The third shell 243 has a first side wall 21 and a second side wall 22. The second shell 242 is provided with a clearance hole 2421. The mounting groove 221 is provided on the third shell 243. The mounting groove 221 is opposite to and communicates with the clearance hole 2421, so that the support member 30 passes through the clearance hole 2421 and the mounting groove 221 in sequence.

[0063] The outer shell 24 consists of a first shell 241, a second shell 242, and a third shell 243. The first shell 241 is fitted around the outer periphery of the third shell 243, and the third shell 243 is fitted around the outer periphery of the second shell 242, forming a coaxial nested structure of the first shell 241, the third shell 243, and the second shell 242. The third shell 243, as the intermediate layer, directly supports the insulating body 10 and has a first sidewall 21 and a second sidewall 22. The second sidewall 22 has a mounting groove 221 extending in a first direction. The second shell 242 is located in the innermost layer, close to the insulating body 10, and has a clearance hole 2421 aligned with the mounting groove 221. During installation, the support member 30 must pass through the mounting groove 221 of the third shell 243 and the clearance hole 2421 of the second shell 242 in sequence, thereby achieving a connection and fixation through multiple shells. This design allows the support member 30 to form a stable connection with the innermost structure, improving the rigidity and tensile strength of the overall structure. Meanwhile, the multi-layered nested structure enhances the mechanical strength, electromagnetic shielding performance, and environmental protection capabilities of the housing. The connection design between the clearance hole 2421 and the mounting groove 221 ensures unobstructed assembly path for the support member 30 while maintaining structural integrity.

[0064] Reference Figures 1 to 7 In this embodiment of the present invention, the electrical connector further includes a plurality of terminals 40, the insulating body 10 includes a base 11 and a tongue plate 12 extending from the base 11 along the first direction, the tongue plate 12 is located between the first sidewall 21 and the second sidewall 22, the plurality of terminals 40 are distributed along the surface of the tongue plate 12, and the plurality of terminals 40 are electrically connected to the circuit board.

[0065] The electrical connector also includes multiple terminals 40 for transmitting electrical signals or power. These terminals 40 are mounted on a specific structure of the insulating body 10 to achieve a stable and reliable electrical connection. Specifically, the insulating body 10 includes a base 11 and a tongue 12 extending from the base 11 along a first direction. The tongue 12 is located between a first sidewall 21 and a second sidewall 22 of the insulating housing 20, forming a protruding interface area for mating plugs or mating connectors. Multiple terminals 40 are distributed and fixed along the surface of the tongue 12 (typically the upper surface, lower surface, or sidewall), with their front ends exposed on the surface of the tongue 12 to make contact with mating terminals, and their rear ends extending to the base 11 and electrically connected to the circuit board (typically through soldering, crimping, or through-hole connection). This design allows the tongue 12 to be accurately inserted into the mating connector during mating, ensuring that each terminal 40 is precisely aligned with the other terminal and establishes a stable electrical contact. The base 11 provides support for the connection between the tail of the terminal 40 and the circuit board, ensuring continuous conduction of signals or current. The arrangement of terminals 40 on the surface of the tongue plate 12 facilitates high-density wiring, increases the number of signal transmission channels in the connector, and effectively prevents short circuits, crosstalk, and interference from the external environment by covering or fixing the terminals 40 with the insulating body 10. Furthermore, the tongue plate 12, located between the first sidewall 21 and the second sidewall 22, is protected by the housing structure and can resist deformation from external forces during insertion and removal, improving the overall rigidity and durability of the terminal group. It is understood that the multiple terminals 40 can be signal terminals, power terminals, ground terminals, or high-speed differential signal terminals.
