Description

Technical field

[0001] The present invention relates to an electrical connector, and in particular to an electrical connector capable of ensuring the stability of terminal abutment. [Background Technology]

[0002] A conventional plug electrical connector comprises an insulating body, terminals housed within the insulating body, and a metal shell covering the insulating body. The metal shell and the insulating body are fixed to each other, the metal shell including a locking portion, and a housing fixed above the circuit board. The housing includes a mating cavity and a snap-fitting groove that locks with the locking portion. Contact pads on the circuit board are exposed in the mating cavity. When the plug connector is moved downward by an external force, the insulating body is assembled into the mating cavity, and the terminals of the plug connector are elastically pressed against the contact pads of the circuit board. To ensure that the locking portion moves downward smoothly and enters the snap-fitting groove of the housing, a gap is generally provided between the locking portion and the upper inner wall of the snap-fitting groove, and to ensure that the elastic deformation of the terminals does not exceed their maximum compression when subjected to the contact force of the contact pads. Therefore, when the force on the plug connector is stopped, the reaction force of the terminals of the plug connector elastically pressing against the contact pads of the circuit board causes the insulating body and the metal shell to float simultaneously until the locking portion abuts against the upper inner wall of the snap-fitting groove. At this time, the compression of the terminals of the plug connector against the circuit board is too small, resulting in unstable contact between the terminals and the contact pads.

[0003] Therefore, it is necessary to design a new electrical connector to overcome the above problems. [Summary of the invention]

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Before the electrical connector is mated with an electronic component, the metal component is assembled to the connector head. The spring element elastically abuts the main body downward, maintaining a distance between the upper plate and the main body. The lower inner wall of the groove abuts the protrusion upward, which restricts the upward movement of the lower inner wall of the groove. When a downward force is applied to the metal component, the upper plate has room to move downward relative to the main body.

[0024] Second, when the force applied to the metal component stops, the upper plate moves upward relative to the main body under the action of the spring sheet to eliminate the gap between the locking portion and the upper inner wall of the fastening groove, driving the locking portion to abut against the upper inner wall of the fastening groove, and the metal component and the shell are locked. Therefore, the distance from the docking surface of the main body to the electronic component in the solution without a spring sheet is greater than the distance from the docking surface of the main body to the electronic component in this solution. This solution can increase the compression amount of the contact spring arm abutting the electronic component, which is beneficial to the stability of the contact spring arm abutting the electronic component.

In other embodiments, the multiple first elastic pins 1511 and the multiple second elastic pins 1512 are configured to elastically abut downwardly against multiple ground contact pads 2012, forming an electrical connection within the electronic component 200. At least one first elastic pin 1511 is provided on the left and right sides of each signal group S, and at least one first elastic pin 1511 is configured between the contact elastic arms 1212 of two adjacent signal groups S in the same row. In this embodiment, two first elastic pins 1511 are provided on the left and right sides of each signal group S, and two first elastic pins 1511 are configured between the contact elastic arms 1212 of two adjacent signal groups S in the same row. The second elastic pin 1512 is located between the contact elastic arms 1212 of two adjacent signal groups S in different rows.

[0062] like Figure 12 and Figure 13 As shown, the grounding member 15 further includes a plurality of first slots 152, a plurality of second slots 153, a plurality of crossbars 154, and a plurality of vertical beams 155. Two first elastic pins 1511 are disposed in a front-to-back arrangement between the contact spring arms 1212 of two adjacent signal groups S in the same row. These two first elastic pins 1511 are defined as first and second pins. The first pins are formed on the metal sheet to form the first slot 152, and the second pins are formed on the metal sheet to form the second slot 153. A crossbar 154 separates the first slot 152 and the second slot 153 between the contact spring arms 1212 of two adjacent signal groups S in the same row in the front-to-back direction. The crossbar 154 is also welded to two adjacent sidewalls 1221 of two adjacent conductive shells 122 in the same row, establishing a grounding path between the grounding member 15 and the two conductive shells 122. Multiple vertical beams 155 are located between the contact spring arms 1212 of two adjacent signal groups S in different rows. The overlapping portion 1232 is welded to the vertical beam 155 to achieve grounding conduction between the grounding member 15 and the conductive member 123 .

[0063] like Figure 4 、 Figure 6 、 Figure 7 and Figure 16As shown, the metal component 2 is disposed on the main body 11 and includes a metal cover 21 and a metal cover 23 disposed outside the metal cover 21. The metal cover 23 is fixed to the metal cover 21. The metal component 2 includes an upper plate P that moves vertically relative to the main body 11. The upper plate P includes an upper cover plate 211 and an upper cover plate 231 stacked in an upper and lower arrangement. The upper plate P is fixed together by laser welding or other means.

[0064] like Figure 16 As shown, the metal cover 21 includes an upper cover 211, two side panels 212 extending downwardly from the left and right sides of the upper cover 211, an elastic plate 213 extending upwardly from one end of each side panel 212 away from the upper cover 211, and a plurality of spring clips 214 extending downwardly from the upper cover 211. In other embodiments, the spring clip 214 may be fixed to the upper cover 211, with the free end of the spring clip 214 extending downwardly relative to the upper cover 211; in other embodiments, there may be only one spring clip 214. The two side panels 212 are located on the left and right sides of the main body 11, and are positioned between the two elastic plates 213 in the left-right direction. Each side panel 212 includes a recess 2121 for accommodating the protrusion 14. Each elastic plate 213 includes at least one locking portion 2131 and a locking hole 2132 located above the locking portion 2131. In this embodiment, each elastic plate 213 includes two locking portions 2131.

[0065] like Figure 2 、 Figure 4 and Figure 16As shown, the metal cover 23 includes an upper cover plate 231 that covers the upper cover plate 211, two end cover plates 232 that bend downward from the front and rear ends of the upper cover plate 231, and two through-holes 233 provided on the left and right sides of the upper cover plate 231. The upper cover plate 231 covers the upper cover plate 211, thereby increasing the reinforcement effect of the corresponding upper cover plate 211 and preventing the upper cover plate 211 from tilting due to the force applied by the spring 214. In the vertical direction, the thickness of the upper cover plate 231 is greater than that of the upper cover plate 211, which makes the upper cover plate 231 more rigid and strengthens the reinforcement effect. In the front-to-back direction, the upper cover plate 211 is located between the two end cover plates 232. The drawstring 3 passes through the through-holes 233 and the buckle holes 2132. The metal cover 21 includes two through-slots 215 provided corresponding to the two through-holes 233. Each through-slot 215 simultaneously passes through the upper cover plate 211 and one of the side plates 212. In other embodiments, each through-slot 215 only extends through the upper cover plate 211 or through only one of the side plates 212. The entire through-hole 233 is located above the corresponding through-slot 215. In other embodiments, the through-hole 233 is partially located above the corresponding through-slot 215. The drawstring 3 passes through the through-hole 233 and the buckle hole 2132. Pulling the elastic plate 213 unlocks the buckle portion 2131 and the buckle slot 302. The drawstring 3 is partially located within the through-slot 215, which provides clearance for the drawstring 3.

[0066] like Figure 17 and Figure 24 FIG. 2 shows a second embodiment of the present invention. In this embodiment, the metal component 2 and the cover 112 differ from those in the first embodiment. For other detailed structures, reference can be made to the detailed description of the first embodiment. In this embodiment, the cover 112 is not provided with a blind groove 1121. The metal component 2 includes a metal cover 21, a metal cover 23, and a connecting portion 22 integrally connecting the metal cover 23 and the metal cover 21. The metal component 2 includes an upper plate P that is movable in the vertical direction relative to the main body 11. The upper plate P includes an upper cover plate 211 and an upper cover plate 231. The connecting portion 22 integrally connects the upper cover plate 211 and the upper cover plate 231.

[0067] like Figure 18 、 Figure 20 and Figure 24As shown, the metal cover 21 includes an upper cover plate 211, two side plates 212 that extend downwardly from the left and right sides of the upper cover plate 211, an elastic plate 213 that extends upwardly from one end of each side plate 212 away from the upper cover plate 211, and a plurality of spring plates 214 that protrude downwardly from the upper cover plate 211. In other embodiments, the spring plates 214 may be fixed to the upper cover plate 211, with the free ends of the spring plates 214 protruding downwardly relative to the upper cover plate 211; in other embodiments, there may be only one spring plate 214. The upper plate P moves vertically relative to the main body 11, with the two side plates 212 located on the left and right sides of the main body 11 and positioned between the two elastic plates 213 along the left-right direction. Each side plate 212 includes a recess 2121 for receiving the protrusion 14. Each elastic plate 213 includes at least one locking portion 2131 and a buckle hole 2132 located above the locking portion 2131. In this embodiment, each elastic plate 213 includes two locking portions 2131. The drawstring 3 passes through the through slot 216 and the buckle hole 2132, and by pulling the elastic plate 213, the locking portion 2131 and the buckle slot 302 are unlocked.

[0068] like Figure 24 As shown, the metal cover 21 includes two through-slots 216 and two through-slots 215 located on the left and right sides of the two through-slots 216. The two through-slots 216 are provided on the left and right sides of the upper cover 211. Each through-slot 215 is separated from its adjacent through-slot 216 by a metal plate and does not communicate with it. In this embodiment, each through-slot 215 penetrates both the upper cover 211 and one of the side panels 212. In other embodiments, the through-slot 215 may penetrate only the upper cover 211 or only one of the side panels 212.

[0069] like Figure 24 As shown, the metal cover 23 includes an upper cover plate 231 and multiple through-holes 234 formed in the upper cover plate 231. In other embodiments, there may be only one through-hole 234. The upper cover plate 211 covers the upper cover plate 231. The spring clip 214 passes through the through-hole 234 and abuts the cover body 112. The drawstring 3 passes through the through-slot 215, which provides space for the drawstring 3.

[0070] like Figures 4 to 9 and Figures 20 to 23 As shown, in the two embodiments of the present invention, the docking process of the electrical connector 100 and the electronic component 200 is as follows:

[0071] like Figure 4 、 Figure 5 、 Figure 20 and Figure 21As shown, before the electrical connector 100 is mated with the electronic component 200, a distance is maintained between the upper plate P and the top surface 11a of the main body 11 along the vertical direction. In the first embodiment, specifically, the elastic piece 214 elastically abuts the bottom wall of the blind groove 1121 downward, and a distance is maintained between the upper cover plate 211 and the top surface 11a of the main body 11. In the second embodiment, specifically, the elastic piece 214 elastically abuts the top surface 11a of the cover body 112 downward, and a distance is maintained between the upper cover plate 231 and the top surface 11a of the cover body 112; the lower inner wall of the groove 2121 abuts the corresponding protrusion 14 upward;

[0072] like Figure 6 、 Figure 9 and Figure 22 As shown, when the electrical connector 100 is mated with the electronic component 200, the main body 11 carries the elastic plate 213 and is inserted downward into the mating cavity 301. When an external force F is applied downward to the metal component 2, the upper plate P moves downward relative to the main body 11, and the elastic sheet 214 is elastically deformed. In the vertical direction, the distance between the upper plate P and the top surface 11a of the main body 11 is reduced, as shown in FIG. Figure 6 As shown in the first embodiment, specifically, the distance between the upper cover plate 211 and the top surface 11a of the main body 11 is reduced, as shown in FIG. Figure 22 As shown, in the second embodiment, specifically, the distance between the upper cover plate 231 and the top surface 11a of the main body 11 is reduced; the lower inner wall of the groove 2121 moves downward and disengages from the corresponding protrusion 14 to form a gap, and the locking portion 2131 is snapped into the corresponding buckling groove 302, and the locking portion 2131 has a distance from the upper inner wall of the corresponding buckling groove 302, as shown in FIG. Figure 9 As shown, the support member 400 is located behind the contact spring arms 1212 of all rows of signal groups S, the first portion 111a is located in front of the support member 400, and the second portion 111b is located above the portion of the support member 400 protruding into the docking cavity 301. The plurality of contact spring arms 1212 are elastically abutted downward against the plurality of contact pads 201 by being blocked by the portion of the support member 400 protruding into the docking cavity 301; Figure 8 and Figure 9 As shown, when the contact elastic arm 1212 elastically abuts the corresponding signal contact pad 2011 downward, the portion of the contact elastic arm 1212 that extends downward beyond the side wall 1221 moves upward relative to the side wall 1221. When viewed in the left and right directions, the projected area of ​​the portion of the contact elastic arm 1212 that extends downward beyond the side wall 1221 is reduced relative to when the contact elastic arm 1212 does not elastically abut the corresponding signal contact pad 2011.

[0073] like Figure 7 and Figure 23As shown, when the force applied to the metal component 2 stops (i.e., the electrical connector 100 is fully docked with the electronic component 200 and the housing 300), the upper plate P moves upward relative to the top surface 11a of the main body 11 under the action of the spring 214, driving the locking portion 2131 upward to abut against the upper inner wall of the corresponding locking groove 302.

[0074] In summary, the electrical connector 100 of the present invention has the following beneficial effects:

[0075] 1. Before the electrical connector 100 is mated with the electronic component 200, the metal component 2 is assembled to the connector 1, and the spring 214 elastically abuts the main body 11 downward, so that the upper plate P maintains a distance from the main body 11. The lower inner wall of the groove 2121 abuts the protrusion 14 upward, and the protrusion 14 limits the upward movement of the lower inner wall of the groove 2121. When a downward force is applied to the metal component 2, the upper plate P has room to move downward relative to the main body 11. When the force on the metal component 2 is stopped (i.e., the electrical connector 100 is fully mated with the electronic component 200 and the housing 300), the spring 214 causes the upper plate P to move relative to the main body. The part 11 moves upward to eliminate the gap between the locking part 2131 and the upper inner wall of the fastening groove 302, driving the locking part 2131 to abut against the upper inner wall of the fastening groove 302, and the metal component 2 and the shell 300 are locked. Therefore, the distance between the docking surface 11b of the main body 11 and the electronic component 200 in the scheme where the metal component 2 is not provided with the spring piece 214 is greater than the distance between the docking surface 11b of the main body 11 and the electronic component 200 in this scheme. This scheme can increase the compression amount of the contact spring arm 1212 abutting against the electronic component 200, which is beneficial to the stability of the contact spring arm 1212 abutting against the electronic component 200.

[0076] 2. The main body 11 includes a top surface 11a facing the metal component 2 and at least one blind groove 1121 recessed from the top surface 11a. Before the electrical connector 100 is mated with the electronic component 200, the spring 214 elastically abuts the bottom wall of the blind groove 1121, maintaining a distance between the upper plate P and the top surface 11a in the vertical direction. This prevents the spring arm of the spring 214 from deforming in the opposite direction when pressed downward, contacting the upper cover plate 231, and causing the spring arm of the spring 214 to deform and fatigue.

[0077] 3. The metal cover 23 includes an upper cover plate 231 covering the upper cover plate 211 and two end cover plates 232 bent downward from the front and rear ends of the upper cover plate 231. The cover plate 211 is located between the two end cover plates 232 in the front-to-back direction. The end cover plates 232 can enhance the overall strength of the metal cover 23, thereby enhancing the overall strength of the metal cover 21.

[0078] 4. The two side walls 1221 of the same conductive shell 122 are located on the left and right sides of the signal fixing portion 1211 and the contact spring arm 1212 of the same signal group S. The contact spring arm 1212 partially extends downwardly beyond the side wall 1221. The portion of the contact spring arm 1212 extending beyond the side wall 1221 is curved. When the contact spring arm 1212 elastically abuts the signal contact pad 2011 downwardly, the portion of the contact spring arm 1212 extending downwardly beyond the side wall 1221 moves upward relative to the side wall 1221. When viewed from the left and right directions, the projected area of ​​the portion of the contact spring arm 1212 extending downwardly beyond the side wall 1221 decreases relative to when the contact spring arm 1212 is not elastically abutting the corresponding signal contact pad 2011. When the force applied to the metal component 2 is stopped ( That is, when the electrical connector 100 is fully docked with the electronic component 200 and the shell 300), the upper plate P moves upward relative to the main body 11 under the action of the spring 214 to eliminate the gap between the locking portion 2131 and the upper inner wall of the snap-fit ​​groove 302, driving the locking portion 2131 upward to abut against the upper inner wall of the snap-fit ​​groove 302, and the metal component 2 and the shell 300 are locked. Therefore, the distance from the conductive shell 122 to the electronic component 200 in the scheme where the spring 214 is not provided on the metal component 2 is greater than the distance from the conductive shell 122 to the electronic component 200 in this scheme. This scheme can shorten the distance from the conductive shell 122 to the electronic component 200, and improve the shielding effect of the conductive shell 122 on the contact spring arm 1212 of the signal group S.

[0079] 5. The conductive shell 122 has a U-shaped structure. Each conductive shell 122 includes two side walls 1221 and an end wall 1222 connecting the two side walls 1221. The two side walls 1221 of the same conductive shell 122 are located on the left and right sides of a signal group S. Two adjacent conductive shells 122 in the same row each have a side wall 1221 located between two adjacent signal groups S in the same row, thereby improving far-end crosstalk between two adjacent signal groups S in the same row. The end wall 1222 of at least one row of conductive shells 122 in the multiple rows is located between two signal groups S in two adjacent rows, thereby improving near-end crosstalk between two adjacent signal groups S in different rows. Grounding Component 15 includes a plurality of first elastic pins 1511 and a plurality of second elastic pins 1512. The first elastic pins 1511 and the second elastic pins 1512 are configured to elastically abut against the ground contact pad 2012 downward. The first elastic pins 1511 are positioned between the contact spring arms 1212 of two adjacent signal groups S in the same row, thereby reducing far-end crosstalk between the contact spring arms 1212 of the two adjacent signal groups S in the same row. The second elastic pins 1512 are positioned between the contact spring arms 1212 of two adjacent signal groups S in different rows, thereby reducing near-end crosstalk between the contact spring arms 1212 of the two adjacent signal groups S in different rows. The ground component 15 is in direct electrical contact with the two sidewalls 1221, achieving a conductive ground path.

[0080] 6. Since the center line O' of the contact area in the front-to-back direction is offset forward relative to the center line O of the portion of the main body 11 located in the docking cavity 301 in the front-to-back direction, when an external force is applied downward to the metal component 2, the multiple contact spring arms 1212 elastically abut the multiple contact pads 201 downward, and the portion of the main body 11 located behind the center line O' of the contact area in the front-to-back direction will be offset downward relative to the portion of the main body 11 located in front of the center line O' of the contact area in the front-to-back direction. The support member 400 is located behind the contact spring arms 1212 of the multiple rows of signal groups S. The first portion 111a is located in front of the support member 400, and the second portion 111b is located above the portion of the support member 400 protruding into the docking cavity 301 and is blocked by the portion of the support member 400 protruding into the docking cavity 301. This can prevent the portion of the main body 11 located behind the center line O' of the contact area in the front-to-back direction from deviating downward, which is beneficial for saving time and effort in locking the electrical connector 100 with the housing 300.

[0081] The above detailed description is only an illustration of the preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all equivalent technical changes made by using the description and illustrations of this invention are included in the patent scope of this invention.
