Technical Field

[0001] This application relates to the field of electronic device technology, and more particularly to an electrical connector. Background Technology

[0002] With the rapid development of electronic devices, the performance of high-performance computing components such as graphics cards continues to improve, and their operating power density has increased significantly. This has led to a corresponding increase in the size and weight of auxiliary functional modules such as heat dissipation modules and power supply modules. Against this backdrop, electrical connectors, as core components that enable electrical signal transmission and mechanical fixation between the motherboard and the graphics card, heat dissipation module, and power supply module, face severe challenges in terms of their mechanical properties, such as friction resistance and impact resistance.

[0003] Therefore, it is necessary to provide an improved electrical connector. Utility Model Content

[0004] The main objective of this invention is to provide an electrical connector that is beneficial for improving structural strength.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an electrical connector, comprising a longitudinally elongated insulating body, conductive terminals, and reinforcing members. The insulating body includes two opposing sidewalls, a through-groove connecting groove between the two sidewalls, and a foolproof portion spanning the connecting groove. The foolproof portion divides the connecting groove into a first groove area and a second groove area. The conductive terminals are respectively disposed on the sidewalls and located on both sides of the connecting groove laterally. The reinforcing member includes a bent body, a first extension, and a second extension connected together.

[0006] The bending body includes a first body covering the top surface of the error-proof part, a second body covering the error-proof part and facing the second groove area, and a third body facing the first groove area. The first extension includes a first extension body extending laterally from the second body and a first bending portion bending from each of the two lateral edges of the first extension body. The first bending portion is fixed to the sidewall and located on the side of the corresponding conductive terminal away from the mating groove. The second extension includes a second extension body extending laterally from the third body and a second bending portion bending from each of the two lateral edges of the second extension body. The second bending portion is fixed to the sidewall and located on the side of the corresponding conductive terminal away from the mating groove.

[0007] Compared with the prior art, the present invention includes a reinforcing member corresponding to the anti-foolproof part in the mating groove. The reinforcing member includes not only a bent body, a first extension body and a second body covering the surface of the anti-foolproof part, which can effectively improve the strength of the anti-foolproof part and reduce the friction of the inserted card against the anti-foolproof part during the insertion process, but also a first and a second bent part fixed to the side wall of the mating groove, which can distribute the impact force received when inserting the card to the two side walls, thereby improving the impact resistance of the electrical connector.

[0027] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0028] To address the shortcomings of traditional electrical connectors in terms of mechanical properties such as friction resistance and impact resistance, this application provides an electrical connector that, through the addition of reinforcing members, enables the electrical connector to possess both excellent friction resistance and impact resistance.

[0029] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the embodiments and features described below can be combined with each other.

[0030] Example 1:

[0031] Firstly, this application provides an electrical connector 10, please refer to... Figures 1 to 6The electrical connector 10 includes a longitudinally elongated insulating body 1, conductive terminals 110, and a reinforcing member 2. The insulating body 1 includes two opposing sidewalls 101, a through-groove mating groove 11 located between the two sidewalls 101, and a foolproof part 12 spanning the mating groove 11. For ease of understanding, the extending direction of the insulating body 1 is defined as the length direction X, the opposing direction of the two sidewalls 101 of the insulating body 1 is defined as the transverse direction Y, and the mating direction between the electrical connector 10 and an electronic card is defined as Z. The length direction X, the transverse direction Y, and the mating direction Z are orthogonal to each other. In this embodiment, the transverse edge refers to the edge that is oppositely arranged along the transverse direction Y, and the transverse extension refers to the extension along the transverse direction Y.

[0032] The foolproof part 12 divides the mating groove 11 into a first groove area 111 and a second groove area 112; conductive terminals 110 are respectively disposed on the side wall 101 and located on both sides of the mating groove 11 laterally. Please refer to [reference needed]. Figure 6 The reinforcing member 2 includes a bent body 21, a first extension 22, and a second extension 23 connected together. The bent body 21 includes a first body 212 covering the top surface of the anti-mistake part 12, a second body 211 covering the anti-mistake part 12 and facing the second groove area 112, and a third body 213 facing the first groove area 111. The first extension 22 includes a first extension body 221 extending laterally from the second body 211 and a first bending part 222 bending from the two lateral edges of the first extension body 221. The second extension 22 and the second extension 23 are embedded in the side wall 101 of the insulating body 1 in the transverse direction Y. The first bending portion 222 is fixed to the side wall 101 and is located on the side of the corresponding conductive terminal 110 away from the mating groove 11. The second extension 23 includes a second extension body 231 extending transversely from the third body 213 and a second bending portion 232 bending from the two transverse edges of the second extension body 231 respectively. The second bending portion 222 is fixed to the side wall 101 and is located on the side of the corresponding conductive terminal 110 away from the mating groove 11.

[0033] A foolproof part 12 is provided in the mating groove 11 of the insulating body 1. The foolproof part 12 can limit the displacement of the inserted card and improve the installation accuracy of the inserted card. In addition, the foolproof part 12 is provided with a reinforcing member 2. The reinforcing member 2 forms a partial covering structure in the foolproof part 12, which reduces the impact of the reinforcing member 2 on the length of the insertable area of ​​the mating groove 11, thereby facilitating the installation of the inserted card. The reinforcing member 2 includes a bending body 21, a first extension 22, and a second extension 23. The bending body 21, the first extension body 221 of the first extension 22, and the second body 211 of the second extension 23 cover at least part of the surface of the foolproof part 12, which can effectively improve the strength of the foolproof part 12, reduce the friction of the electronic card with the foolproof part 12 during the insertion process, and thus improve the friction resistance and impact resistance of the electrical connector 10. By connecting the second body 211, the first body 212 and the third body 213, the top surface and two surfaces of the anti-foolproof part 12 can be respectively attached and covered, so that the reinforcing member 2 can better receive the impact force received by the electrical connector 10 during operation and disperse the impact force to the insulating body 1, thereby improving the impact resistance of the electrical connector 10 along the length direction X and the mating direction Z.

[0034] The insulating body 1 is a mounting base for components such as conductive terminals 110, metal housing 3 and reinforcing members 2. The insulating body 1 includes a top wall 102 and a bottom wall 103. The mating groove 11 is opened from the top wall 102 toward the bottom wall 103 for the insertion of electronic cards such as graphics cards.

[0035] Please refer to Figures 1 to 3 The insulating body 1 also has two rows of terminal mounting holes 13 for mounting conductive terminals 110. The two rows of terminal mounting holes 13 are located on both sides of the mating groove 11 along the length direction X, and the two ends of the terminal mounting holes 13 penetrate the top wall 102 and the bottom wall 103 of the insulating body 1 along the mating direction Z. Please refer to Figure 2 The two rows of terminal mounting holes 13 include a row of first terminal holes 131 and a row of second terminal holes 132, which communicate with the mating groove 11. The first terminal holes 131 and the second terminal holes 132 are used to install conductive terminals 110, so that after the electronic card is mated with the mating groove 11, the portion of the conductive terminals 110 extending into the mating groove 11 from the first terminal holes 131 and the second terminal holes 132 can be connected to the electronic card, thereby realizing a reliable electrical connection and stable signal transmission between the electronic card and the electrical connector 10.

[0036] Please refer to Figure 3 The error prevention part 12 is a plate-like structure inside the mating groove 11, which can be integrally formed with the insulating body 1. By setting the error prevention part 12, errors such as incorrect insertion direction, poor contact or damage to the electrical connector 10 can be reduced during the mating process. It can also limit the displacement of the insertion card during the operation of the electrical connector 10, ensuring the stable installation of the insertion card.

[0037] Please refer to Figure 6 The reinforcing member 2 is fixed to the anti-misalignment part 12 along the docking direction Z to enhance the strength of the anti-misalignment part 12. Specifically, the bending body 21 of the reinforcing member 2 matches the shape of the anti-misalignment part 12, and is approximately a U-shaped structure. The first extension 22 and the second extension 23 are respectively provided at both ends of the bending body 21. Both are sheet-like structures parallel to the plane containing the docking direction Z and the transverse direction Y, and the width of the first extension 22 and the second extension 23 along the transverse direction Y is greater than the width of the bending body 21. Thus, through the bending body 21, The arrangement of the first extension 22 and the second extension 23 allows the reinforcing member 2 to cover the top surface and two surfaces of the foolproof part 12, effectively improving the strength of the foolproof part 12 and reducing the friction between the electronic card and the foolproof part 12 during insertion. It also effectively disperses the impact force along the length direction X into the insulating body 1, thereby improving the friction resistance and impact resistance of the electrical connector 10. At the same time, the covering design of the reinforcing member 2 on the foolproof part 12 does not reduce the impact on the length of the pluggable area of ​​the mating groove 11, thus facilitating the installation of the inserted card.

[0038] The first extension body 221 of the first extension portion 22 and the second extension body 231 of the second extension portion 23 cover the two side surfaces of the anti-mistake part 12 along the length direction X of the electrical connector 10, and the first extension body 221 and the second extension body 231 extend into the side wall 101 along the transverse direction Y. The first bending portion 222 and the second bending portion 232 are both sheet-like structures and are parallel to the side wall 101, respectively, and the first bending portion 222 and the second bending portion 232 are located inside the side wall 101. The arrangement of the first extension body 221 and the second extension body 231 can improve the installation strength of the reinforcing member 2 in the anti-mistake part 12, and further improve the impact resistance of the anti-mistake part 12 along the length direction X. That is, the first extension portion 22 and the second extension portion 23 have the functions of covering the surface of the anti-mistake part 12 and improving the installation stability of the reinforcing member 2; and when the reinforcing member 2 is subjected to an impact force along the transverse direction Y, the first bending portion 222 and the second bending portion 232 can better disperse the impact force to the insulating body 1.

[0039] The first extension 22 includes a first strip portion 223 that bends from the first bending portion 222 and extends out of the sidewall 101, and the second extension 23 includes a second strip portion 233 that bends from the second bending portion 232 and extends out of the sidewall 101. The arrangement of the first strip portion 223 and the second strip portion 233 allows for more structures of the first extension portion 22 and the second extension portion 23 embedded in the insulating body 1, which can further improve the installation stability of the reinforcing member 2; and the first strip portion 223 and the second strip portion 233 can disperse the impact force in the mating direction Z to the insulating body 1, thereby improving the impact resistance of the electrical connector 10 in the mating direction Z.

[0040] See Figure 6 The second main body 211 and the third main body 213 are arranged in a staggered configuration when viewed laterally. This reduces the amount of material used in the reinforcing member 2 while still improving the strength of the two surfaces of the anti-foolproof part along its length. The distance between the first extension 22 and the top surface of the insulating body 1 is less than the distance between the second extension 23 and the top surface of the insulating body 1. The first extension 22 and the second extension 23 are embedded in the sidewall 101, fixing the reinforcing member 2 to the upper and lower parts of the insulating body 1 respectively, thus enhancing the installation stability of the reinforcing member 2.

[0041] Viewed from a direction perpendicular to the first main body 212, the projections of the first extension 22 and the second extension 23 do not overlap, and the first extension 22 and the second extension 23 can better disperse the impact force along the length direction X.

[0042] Please refer to Figure 2 and Figure 3 The metal housing 3 covering at least a portion of the outer surface of the insulating body 1 is generally rectangular. The rectangular housing has a receiving cavity 31, and both the top and bottom of the metal housing 3 have openings. When the metal housing 3 is assembled with the insulating body 1, at least a portion of the insulating body 1 can enter the receiving cavity 31 through the bottom opening of the metal housing 3. The top opening does not affect the installation of the electronic card and the conductive terminal 110. Thus, the metal housing 3 resists external forces such as vibration, impact, or compression, reducing or even avoiding the impact of external forces on components such as the insulating body 1 and the conductive terminal 110.

[0043] The bottom surface of the metal housing 3 along the mating direction Z also includes two pairs of support members 32, which are disposed at both ends of the metal housing 3 along the length direction X. Specifically, the metal housing 3 includes two walls along the transverse direction Y, and the bottom of the two walls extends along the mating direction Z to form sheet-like support members 32, and support members 32 are provided at both ends of the same wall along the length direction X. The electrical connector 10 can be supported and fixed to the equipment chassis by the support members 32, ensuring precise mating between the electrical connector 10 and the equipment; furthermore, the support members 32 are made of metal, and their high rigidity can provide buffering and support for the electrical connector 10 during operation, absorbing vibrations during equipment operation and ensuring the installation stability of the electrical connector 10 on the equipment.

[0044] The metal housing 3 is also provided with outwardly protruding relief protrusions 33 corresponding to the first and second material strips 233. The setting of the relief protrusions 33 can ensure the correct installation of the metal housing 3 and the insulating body 1.

[0045] Example 2:

[0046] Unlike Example 1, please refer to Figures 7-10The reinforcing member 2 is a sheet-like structure embedded inside the anti-misalignment part 12, and the metal housing 3 has a self-extending structure, so that when the metal housing 3 is installed on the insulating body 1, the self-extending structure covers both ends of the anti-misalignment part 12 and the insulating body 1 along the length direction X, thereby improving the friction resistance and impact resistance of the electrical connector 10. Specifically:

[0047] See Figure 9 The anti-mistake part 12 has a sheet-like reinforcing member 2 embedded inside, which can enhance the overall strength and surface strength of the anti-mistake part 12. When the anti-mistake part 12 is impacted, it can disperse the force to the insulating body 1.

[0048] The reinforcing member 2 used in Example 2 can be a 0.4mm stainless steel sheet.

[0049] The metal housing 3 has a third extension 34 and a fourth extension 35 at both ends, and a fifth extension 36 corresponding to the foolproof part 12. The third extension 34 and the fourth extension 35 are approximately L-shaped, and the fifth extension 36 is approximately U-shaped. The fifth extension 36 specifically includes a fourth body 361, a fifth body 362, and a sixth body 363. When the insulating body 1 is received into the receiving cavity 31 of the metal housing 3, the third extension 34 covers at least a portion of the end face of the second groove area 112 away from the first groove area 111, the fourth extension 35 covers at least a portion of the end face of the first groove area 111 away from the second groove area 112, the fourth body 361 of the fifth extension 36 covers at least a portion of the surface of the foolproof part 12 facing the second groove area 112 along the length direction X, the fifth body 362 covers the top surface of the foolproof part 12 along the mating direction Z, and the sixth body 363 covers at least a portion of the surface of the foolproof part 12 facing the first groove area 111 along the length direction X. That is, through the design of the third extension 34, the fourth extension 35 and the fifth extension 36, the impact force can be better distributed to the insulating body 1.

[0050] As an optional technical solution of this application, after setting the fifth extension 36 and the reinforcing member 2, the metal ratio of the anti-fooling position can reach 50.56%.

[0051] Compared to Embodiment 1, the assembly method of the insulating body 1 and the reinforcing member 2 in Embodiment 2 can be installation or injection molding, which will not affect the appearance and size of the insulating body 1.

[0052] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
