Abstract
Description
[Technical Field]
[0001] This invention relates to an electrical connector, and more particularly to an electrical connector that electrically connects a mating component and a circuit board. [Background Technology]
[0002] An existing electrical connector includes a base, a cover that engages with the base, and multiple conductive terminals housed in the base. The base has sidewalls and mounting grooves. The sidewalls have multiple pivots and multiple receiving grooves. A receiving groove is provided between two adjacent pivots. The mounting groove houses a mating element with multiple pins. The mating element has multiple pins. One side of the cover has multiple pivots and multiple pivot arms connecting the pivots. The multiple pivots are pivotally connected to the pivots. The receiving groove houses the pivot arms and the pins. The pivot arms press against the pins. To facilitate the assembly of the cover into the base, sufficient space is reserved between the pivots and adjacent pivot arms in the initial design phase, allowing the pivots and pivot arms to rotate in a relatively relaxed environment.
[0003] However, the problem with the above structure is that, since there is enough space reserved between the pivot and the adjacent pivot arm, it can rotate freely. This results in the pivot arm moving a large distance laterally toward the pivot after the cover is pivotally connected to the base. As a result, the cover and the base are easily misaligned, resulting in a loose fastening. In addition, when the pivot arm presses against the joint, it may shift to the left or right, resulting in incomplete or even impossible pressing.
[0004] Therefore, it is necessary to design a new electrical connector to overcome the above problems. [Summary of the Invention]

The receiving groove 111 is located below the receiving groove 112 and extends to the bottom wall 13. The width of the receiving groove 111 in the left-right direction is smaller than the width of the receiving groove 112. Each receiving groove 111 is provided with a fixing groove 1111 and a fastening groove 1112 located below the fixing groove 1111.

Each first pivot portion 1131 has a first portion 11311 and a second portion 11312 connecting the first portion 11311. The second portion 11312 is located outside the first portion 11311 in the front-back direction. The side of the second portion 11312 away from the first pivot arm 221 is flush with the first portion 11311. The width of the second portion 11312 in the left-right direction is less than the width of the first portion 11311. Each of the first pivot portions 1131 is further provided with an inclined surface 11313 located on one side of the receiving groove 112 and a vertical surface 11314 near the side of the first pivot arm 221.
[0042] like Figures 1 to 10As shown, the cover 20 has a pivot 21, multiple pivot arms 22 arranged in a row along the left and right direction, and multiple assembly slots 223 on one side. The cover 20 has two locking arms 224, two wall portions 225, and two operating portions 226 located on the left and right sides, and the locking arms 224 are engaged with the base 10. The multiple pivot arms 22 are connected to the pivot 21; in other embodiments, the cover 20 has multiple pivots 21 on one side, and the multiple pivot arms 22 are connected to the multiple pivots 21; in other embodiments, each locking arm 224, wall portion 225, and operating portion 226 can be provided as one, located on the left or right side of the pivot 21. The multiple pivot portions 113 are pivotally connected to the pivot 21, each receiving slot 112 accommodates one pivot arm 22, and each assembly slot 223 is located between two adjacent pivot arms 22 to accommodate one pivot portion 113. The operating part 226 is located above the locking arm 224 and connects the wall part 225 and the locking arm 224.
[0043] like Figures 3 to 4 As shown, the plurality of pivot arms 22 have two first pivot arms 221 located on the outer sides in the left-right direction and a plurality of second pivot arms 222 located between the two first pivot arms 221. The first pivot arms 221 and the second pivot arms 222 are interconnected by the pivot shaft 21. The wall portion 225 connects the first pivot arms 221 and the locking arm 224. In other embodiments, only one second pivot arm 222 is provided. The width of the first pivot arm 221 in the left-right direction is greater than the width of the second pivot arm 222. A first gap D1 is formed between the first pivot arm 221 and the adjacent first pivot portion 1131 in the left-right direction, and a second gap D2 is formed between the second pivot arm 222 and the adjacent second pivot portion 1132 in the left-right direction. The first gap D1 is smaller than the second gap D2. The first pivot arm 221 has a first gap D1 in the left-right direction with the adjacent first part 11311, and the first pivot arm 221 has a third gap D3 in the left-right direction with the adjacent second part 11312, wherein the first gap D1 is smaller than the third gap D3.
[0044] like Figures 4 to 5As shown, the first pivot arm 221 has an arm portion 2211 and a stop portion 2212 located outside the arm portion 2211 in the front-rear direction. The stop portion 114 is used to stop the stop portion 2212 from displacing in the pivoting direction of the pivot shaft 21. The side of the stop portion 2212 away from the first pivot portion 1131 is flush with the arm portion 2211, and the width of the stop portion 2212 in the left-right direction is smaller than the width of the arm portion 2211. The first gap D1 is located between the first portion 11311 and the arm portion 2211, and the third gap D3 is located between the second portion 11312 and the stop portion 2212. The stop portion 2212 has a recess 22121 near the first pivot portion 1131, which can provide clearance and prevent the stop portion 2212 from easily abutting against the first pivot portion 1131 and causing friction when it moves along the pivot direction of the rotating shaft 21, thus preventing damage to the stop portion 2212 or the first pivot portion 1131.
[0045] like Figures 8 to 10 As shown, the assembly groove 223 has a lower inclined surface 2231, which is opposite to the rotating shaft 21. Along the front-back direction, the lower inclined surface 2231 has a first edge 22311 on the outer side and a second edge 22312 on the inner side. When the cover 20 is closed with the base 10, the first edge 22311 is higher than the second edge 22312.
[0046] like Figure 5 As shown, each locking arm 224 is provided with a first reinforcing part 2241, a second reinforcing part 2242, a third reinforcing part 2243, and a locking hook part 2244. The first reinforcing part 2241 and the second reinforcing part 2242 are respectively located on the front and rear sides of the third reinforcing part 2243, and the two third reinforcing parts 2243 protrude from the first reinforcing part 2241 in the left-right direction. The first reinforcing part 2241 is connected upward to the wall part 225, and the lower end of the first reinforcing part 2241 is higher than the locking hook part 2244. The second reinforcing part 2242 is connected upward to the operating part 226 and extends downward to the locking hook part 2244. The third reinforcing part 2243 is connected upward to the operating part 226 and extends downward to the locking hook part 2244.
[0047] like Figures 6 to 7As shown, multiple conductive terminals 30 are respectively inserted into and positioned in multiple receiving slots 111 along the front-back direction. Each conductive terminal 30 has a fixing part 31, an elastic arm 32 extending upward from the fixing part 31, a snap-fit arm 33 located below the fixing part 31, and a main body 34 connecting the fixing part 31 and the snap-fit arm 33. The partition wall 12 is located between the fixing part 31 and the snap-fit arm 33. The fixing part 31 is received in the fixing slot 1111, a part of the elastic arm 32 is located in the receiving slot 112 and abuts upward against the second pivot arm 222, the opening 11121 allows the snap-fit arm 33 to move, the snap-fit arm 33 is located below the fixing part 31 and is received in the snap-fit slot 1112 to snap into the snap-fit part 15, and the main body 34 is soldered downward to the circuit board 300.
[0048] like Figures 6 to 7 As shown, the latching arm 33 has an upwardly arranged abutment portion 331 connecting to the main body portion 34, an elastic portion 332 connecting to the abutment portion 331, and a latching portion 333 located above the elastic portion 332. The partition wall 12 simultaneously abuts against the fixing portion 31 and the abutment portion 331, and the elastic portion 332 has a gap with the partition wall 12. The latching portion 333 is loosely engaged with the fastening portion 15, and the fastening portion 15 limits the latching portion 333 from displacing outward from the receiving groove 111 in the front-back direction. The latching part 333 is provided with a second guide slope 3331 facing the inside of the receiving groove 111 and a second stop surface 3332 facing the outside of the receiving groove 111 in the front-back direction. When the latching arm 33 enters the fastening groove 1112, the first guide slope 151 and the second guide slope 3331 guide each other to slide into contact until the first stop surface 152 restricts the second stop surface 3332 from moving backward.
[0049] like Figure 4 and Figure 7 As shown, the docking element 200 is provided with a plurality of contact portions 2001, each of which is received in a corresponding receiving groove 112. The second pivot arm 222 abuts downward against the contact portion 2001, and the inclined surface 11313 guides the contact portion 2001 into the receiving groove 112, with the contact portion 2001 abutting downward against the inner bottom surface 1121.
[0050] In summary, the electrical connector of the present invention has the following beneficial effects:
[0051] (1) The cover 20 is pivotally connected to the first pivot portion 1131 and the second pivot portion 1132 via the pivot 21, so that one side of the cover 20 is pivotally connected to the base 10. The first pivot arm 221 has a first gap D1 with the adjacent first pivot portion 1131, and the second pivot arm 222 has a second gap D2 with the adjacent second pivot portion 1132. The first gap D1 is smaller than the second gap D2, ensuring that the first pivot arm 221 and the adjacent first pivot portion 1132 are pivotally connected. The relatively small gap between the pivot parts 1131 prevents the cover 20 from moving a large distance laterally after being pivoted to the base 10, further ensuring that the cover 20 rotates and closes properly with the base 10, and that the fit is tight. On the other hand, the relatively large gap between the second pivot arm 222 and the adjacent second pivot part 1132 prevents frictional interference between the second pivot arm 222 and the second pivot part 1132 when the cover 20 rotates, ensuring a loose fit between the cover 20 and the base 10.
[0052] (2) The first pivot arm 221 and the adjacent first part 11311 have a first gap D1 in the left-right direction, and the first pivot arm 221 and the adjacent second part 11312 have a third gap D3 in the left-right direction. The first gap D1 is smaller than the third gap D3. When the cover 20 is closed with the base 10, the first pivot arm 221 and the first part 11311 are tightly fitted, which can prevent the cover 20 from being relatively loose in the left-right direction after it is pivotally connected to the base 10, and further ensure that the position of the cover 20 rotating and closing with the base 10 is appropriate. When the cover 20 is opened, the first pivot arm 221 is displaced along the pivot direction of the pivot axis 21. Since the first pivot arm 221 and the second part 11312 are loosely fitted, it is beneficial for the first pivot arm 221 to be loose, which facilitates the rotation of the first pivot arm 221.
[0053] (3) When the cover 20 is pivotally opened via the pivot 21, the stop part 2212 moves along the pivot direction of the pivot 21 and stops at the stop part 114. The stop part 114 restricts the excessive pivoting of the cover 20 by stopping the displacement of the stop part 2212. The stop part 2212 is provided with a recess 22121 near the first pivot part 1131, which can prevent the stop part 2212 from easily abutting against the first pivot part 1131 when it moves along the pivot direction of the pivot 21, thereby avoiding damage to the stop part 2212 or the first pivot part 1131. Since the arm part 2211 will not abut against the first pivot part 1131 when it moves along the pivot direction of the pivot 21, the width of the arm part 2211 in the left-right direction is designed to be greater than the width of the stop part 2212, which can ensure the structural strength of the first pivot arm 221 and prevent easy breakage.
[0054] (4) Since the receiving groove 111 receives the conductive terminal 30, in order to avoid the conductive terminal 30 from loosening, the width of the receiving groove 111 is set to be smaller, while the receiving groove 112 receives the first pivot arm 221, and the width of the receiving groove 112 is set to be larger. When the cover 20 is pivoted to be fully open, a part of the elastic arm 32 of the conductive terminal 30 is located in the receiving groove 112 and abuts against the second pivot arm 222 upward, which can support the second pivot arm 222 and prevent the cover 20 from falling off the base 10.
[0055] (5) When the cover 20 pivots and engages with the base 10, the second pivot arm 222 abuts against the contact portion 2001 downwards, and the contact portion 2001 abuts against the inner bottom surface 1121 downwards. The inner bottom surface 1121 can prevent the second pivot arm 222 from excessively pressing against the contact portion 2001, ensuring that the contact portion 2001 will not deform.
[0056] (6) When the cover 20 pivots through the pivot 21, the lower inclined surface 2231 rotates around the first pivot portion 1131 or the second pivot portion 1132. The lower inclined surface 2231 has a first edge 22311 on the outer side and a second edge 22312 on the inner side along the front-back direction. The first edge 22311 is higher than the second edge 22312. The lower inclined surface 2231 provides clearance space to prevent the cover 20 from interfering with the first pivot portion 1131 or the second pivot portion 1132 when pivoting.
[0057] (7) Since the first pivot arm 221 and the first pivot joint 1131 are both located on the outer sides in the left-right direction, and the first pivot arm 221 and the first pivot joint 1131 are adjacent, the width of the first pivot arm 221 is greater than the width of the second pivot arm 222, and the width of the first pivot joint 1131 is greater than the width of the second pivot joint 1132. This ensures the structural strength of the first pivot arm 221 and the first pivot joint 1131, preventing easy breakage. The width of the second pivot arm 222 and the second pivot joint 1131 are also greater than the width of the second pivot joint 1132. The smaller width of 32 avoids affecting the overall size of the electrical connector 100 and ensures the ease of pivoting the cover 20. The first pivot arm 221 and the second pivot arm 222 are connected to each other by a pivot shaft 21, ensuring that the first pivot arm 221 and the second pivot arm 222 maintain their fixed positions during the pivoting process. This prevents the second pivot part 1132 from deforming more easily due to its smaller width during pivoting, and helps to further strengthen the overall structural strength of the first pivot arm 221 and the second pivot arm 222.
[0058] (8) The stop part 2212 is connected to the rotating shaft 21. Setting the stop part 2212 close to the axis of rotation of the cover 20 is beneficial to controlling the rotation range of the cover 20 and to ensuring that the stop part 2212 stops at the stop part 114 with sufficient force. On this basis, the first pivot arm 221 and the second pivot arm 222 are connected to each other through the rotating shaft 21 to ensure that the first pivot arm 221 and the second pivot arm 222 maintain their fixed positions during the pivoting process, avoid the second pivoting part 1132 from easily deforming during the pivoting, and help to strengthen the overall structural strength of the first pivot arm 221 and the second pivot arm 222.
[0059] (9) The first pivot portion 1131 is provided with an inclined surface 11313 located on one side of the receiving groove 112, for guiding the contact portion 2001 into the receiving groove 112; the first pivot arm 221 is provided with a stop portion 2212, and the side wall 11 has a stop portion 114, the stop portion 114 is used to stop the stop portion 2212 from displacing along the pivot direction of the rotating shaft 21, thereby limiting the excessive pivoting of the cover 20. When human error causes the cover 20 to pivot excessively on the base 10, the excessive pressure is transmitted from the stop portion 2212 to the rotating shaft 21, and the rotating shaft 21 will pry the first pivot portion 1131 into the base 10. The first pivot portion 1131 has an inclined surface 11313 on one side to facilitate guiding the contact portion 2001 of the docking element 200 into the receiving groove 112. If the side near the first pivot arm 221 were also designed with an inclined surface 11313, the lever arm of the first pivot portion 1131 would become weaker, making it prone to breakage under the radial destructive force of the rotating shaft 21. Furthermore, the area on the left and right sides of the first pivot portion 1131 would be smaller, increasing the pressure exerted by the first pivot arm 221 in the left-right direction, further increasing its susceptibility to breakage. Therefore, providing a vertical surface 11314 near the first pivot arm 221 helps strengthen the structural strength of the first pivot portion 1131 and prevents breakage during use.
[0060] (10) The latch arm 224 of the cover 20 is provided with a first reinforcing part 2241, a second reinforcing part 2242 and a third reinforcing part 2243. The first reinforcing part 2241 and the second reinforcing part 2242 are respectively located on the front and rear sides of the third reinforcing part 2243. The third reinforcing part 2243 protrudes from the first reinforcing part 2241 in the left and right direction, which is beneficial to strengthening the overall structural strength of the latch arm 224 and preventing the latch arm 224 from easily breaking when it is fastened to the base 10.
[0061] (11) The operating part 226 facilitates the operator to open or close the cover 20. The first reinforcing part 2241 is connected upward to the wall part 225 and the lower end of the first reinforcing part 2241 is higher than the locking hook part 2244. This not only helps the locking arm 224 to strengthen the structural strength between itself and the wall part 225, but also ensures that it will not interfere with the cover 20. The second reinforcing part 2242 is connected upward to the operating part 226 and extends downward to the locking hook part 2244. This helps the locking arm 224 to strengthen the structural strength between itself and the operating part 226. The third reinforcing part 2243 is connected upward to the operating part 226 and extends downward to the locking hook part 2244. This helps the locking arm 224 to strengthen the structural strength between itself and the operating part 226. The design of the first reinforcing part 2241, the second reinforcing part 2242 and the third reinforcing part 2243 can ensure the overall structural strength of the locking arm 224.
[0062] (12) The fixing part 31 is received in the fixing groove 1111 and fixedly engaged with the base 10. The latching arm 33 is located in the latching groove 1112 and latches with the latching part 15. Because the latching arm 33 is relatively long, it is more flexible and can avoid damage when it latches with the latching part 15 through elastic deformation in the latching groove 1112. The conductive terminal 30 is fixed in the fixing groove 1111 and the latching groove 1112 respectively by the fixing part 31 and the latching arm 33, which is conducive to the conductive terminal 30 being firmly secured in the receiving groove 111.
[0063] (13) The fastening part 15 is located above the fastening groove 1112 and the fastening groove 1112 is open downward with an opening 11121, which provides space for the buckling arm 33 to elastically deform when it enters the fastening groove 1112 and passes through the fastening part 15. The buckling arm 33 elastically displaces downward at the opening 11121. After passing through the fastening part 15, the buckling arm 33 springs back upward to reset and engages with the fastening part 15.
[0064] (14) The fastening part 15 is provided with a first guide slope 151 facing outward from the receiving groove 111 and a first stop surface 152 on the inner side in the front-back direction. The latching part 333 is provided with a second guide slope 3331 facing inward from the receiving groove 111 and a second stop surface 3332 on the outer side in the front-back direction. When the latching arm 33 enters the fastening groove 1112, the first guide slope 151 and the second guide slope 3331 contact each other to provide guidance for the latching part 333 to pass through the fastening part 15. When the latching arm 33 exits the fastening groove 1112, the first stop surface 152 and the second stop surface 3332 contact each other to provide a blocking effect for the latching part 333 to exit the fastening part 15.
[0065] (15) When the fastening part 15 and the latching part 333 are engaged, the partition wall 12 is located between the fixing part 31 and the latching arm 33 and simultaneously abuts against the fixing part 31 and the abutting part 331. This helps to further secure the conductive terminal 30 in the receiving groove 111. At the same time, the abutting part 331 abutting against the partition wall 12 will also reduce the elastic fatigue of the latching arm 33 and prevent the latching arm 33 from becoming loose due to gravity, which would cause the latching part 333 to shift downward and fail to engage with the fastening part 15. The elastic part 332 has a gap with the partition wall 12, which reduces the contact area between the elastic part 332 and the base 10. This helps to ensure the flexibility of the elastic deformation of the elastic part 332 and further facilitates the engagement of the latching part 333 with the fastening part 15.
