[ detailed description ] of the invention

For a better understanding of the present utility model, reference will now be made in detail to the present utility model, examples of which are illustrated in the accompanying drawings.

As shown in fig. 1 to 10, the power connector 100 of the present utility model defines a front-rear direction, and a left-right direction and an up-down direction perpendicular to the front-rear direction. For the convenience of understanding the drawings, the forward direction in the front-rear direction is the positive direction of the X axis, the rightward direction in the left-right direction is the positive direction of the Y axis, and the upward direction in the up-down direction is the positive direction of the Z axis.

As shown in fig. 1 to 7, in the power connector 100 according to the first embodiment of the present utility model, the power connector 100 is configured to be electrically contacted with two docking elements 200 upwards and soldered with a circuit board 300 downwards, and includes two power contacts 1 and two conductive plates 2 corresponding to the two power contacts 1 respectively, wherein the two conductive plates 2 are assembled with the two power contacts 1 in a one-to-one correspondence, and each power contact 1 is located above the corresponding conductive plate 2 and is assembled and fixed on the corresponding conductive plate 2. Each power contact 1 is abutted upward against the corresponding abutting element 200, and the lower surfaces of the two conductive plates 2 are soldered to the same circuit board 300.

As shown in fig. 1, 3, 5 and 7, each of the power contacts 1 is formed by stamping and bending a metal plate (in this embodiment, the base material of the power contact 1 is a copper alloy, although in other embodiments, the power contact 1 may be made of other metal materials). Each power contact 1 has a plurality of connection bars 11, opposite sides of the connection bars 11 located in the middle of each power contact 1 are respectively bent upwards to extend a plurality of power contact arms 12, and are arranged in two rows along the extending direction of the connection bars 11 (i.e. along the left-right direction), only one side of each of the two connection bars 11 located at the front and rear edges of each power contact 1 is connected with the power contact arm 12, and the plurality of power contact arms 12 are used for elastically interfacing with the interfacing element 200. Specifically, in this embodiment, the number of the connection bars 11 is plural, the connection bars 11 are arranged in the front-rear direction, a plurality of rows of the power contact arms 12 extend from the connection bars 11, each connection bar 11 extends in the left-right direction, the front and rear longitudinal side edges of each connection bar 11 located in the middle extend toward the far side from each other and are bent with a plurality of the power contact arms 12, the inner side edges of the two connection bars 11 at the front and rear side edges are bent with a plurality of the power contact arms 12, and the plurality of the power contact arms 12 at each side are arranged in a row in the left-right direction. The power contact arms 12 of one of the two power contacts 1 and the corresponding conductive plate 2 are electrically connected to transmit an input current, and the power contact arms 12 of the other power contact 1 and the corresponding conductive plate 2 are electrically connected to transmit an output current, so that the docking element 200 and the circuit board 300 can perform input and output of a power supply through the power connector 100.

As shown in fig. 1, 3, 5 and 7, one end of each of the power contact arms 12 is connected to the connecting bar 11, and the other end is a free end. Each power contact arm 12 has a bending portion 121 at a side near the connecting bar 11, and two elastic contact sections 122 extend upward from the bending portion 121, where the two elastic contact sections 122 are spaced apart from each other along the left-right direction. A first blanking groove 123 is arranged between two adjacent power contact arms 12 in the same row, and the first blanking groove 123 provides a relief for deformation of the power contact arms 12. A second blanking groove 124 is provided between the two elastic contact sections 122 of the same power contact arm 12, the length of the first blanking groove 123 is longer than that of the second blanking groove 124 when seen in the front-back direction, and the first blanking groove 123 is closer to the connecting strip 11 connected with the power contact arm 12 than the second blanking groove 124, so that the elastic contact sections 122 of the power contact arm 12 can be ensured to have sufficient strength. The width of the first blanking groove 123 is smaller than the width of the elastic contact section 122 along the left-right direction, and the width of the first blanking groove 123 is equal to the width of the second blanking groove 124 along the left-right direction, so that the power contact 1 can be provided with more power contact arms 12 on the premise of limited volume, and the power contact 1 can transmit more current.

As shown in fig. 1, 3, 5 and 7, each power contact arm 12 has two small-area elastic contact sections 122, each elastic contact section 122 has a curved arc surface 1221, and the curved arc surface 1221 is bent upwards and is butted with the docking element 200, so that compared with the case that each power contact arm 12 is only provided with one elastic contact section 122 having a larger area, the area of the curved arc surface 1221 of the large-area elastic contact section 122 is also larger, but the coplanarity of the curved arc surface 1221 is deviated due to the surface arc shape of the curved arc surface 1221, and the effective contact area of the curved arc surface 1221 and the docking element 200 is far smaller than the area of the curved arc surface 1221. However, the coplanarity of the curved arc surfaces 1221 of each of the two elastic contact sections 122 disposed at a distance from each other is better controlled than that of the large-area curved arc surfaces 1221, so that the sum of the actual contact areas of the curved arc surfaces 1221 of the two elastic contact sections 122 is larger than that of the curved arc surfaces 1221 of one large-area elastic contact section 122, which can increase the current carrying capacity of the power contact arm 12. Moreover, since each of the power contact arms 12 has two elastic contact sections 122, compared with a case that only one elastic contact section 122 is provided on one of the power contact arms 12 to contact with the docking element 200, the two elastic contact sections 122 not only increase the contact point with the docking element 200, reduce the impedance and thus reduce the heat generation, which is beneficial for the power connector 100 to transmit a large current, but also improve the forward force of the contact of the power contact arms 12 relative to the one elastic contact section 122, thereby avoiding the fatigue of the power contact arms 12.

As shown in fig. 5 and 7, each connecting bar 11 is bent towards an adjacent connecting bar 11 to extend a row of power contact arms 12, the free ends of two adjacent rows of power contact arms 12 of two adjacent connecting bars 11 are opposite and spaced apart from each other, and the spacing between the free ends of two adjacent rows of power contact arms 12 in the front-rear direction is greater than the width of the first blanking groove 123 and the second blanking groove 124, so that when the power contact arms 12 are pressed and deformed downwards, the free ends of two adjacent rows of power contact arms 12 of two adjacent connecting bars 11 have enough spacing to provide a yielding position for the power contact arms 12, thereby avoiding the collision between the free ends of two adjacent rows of power contact arms 12.

As shown in fig. 1, 2, 3, 5, 6 and 7, the power contact 1 has two bridging portions 13, two bridging portions 13 are located on the left and right sides of the plurality of connection bars 11, and two bridging portions 13 are respectively connected to the left and right sides of the plurality of connection bars 11.

Before the docking element 200 is docked with the power connector 100 downward, the power contact arm 12 is higher than the convex hull 14 along the up-down direction, and when the docking element 200 is docked with the power connector 100 downward, the convex hull 14 can abut the docking element 200 upward, so that the convex hull 14 can stop the power contact arm 12 from being over-pressed.

As shown in fig. 1 and 3, the left and right ends of each of the two connection bars 11 located at the front and rear side edges of the power contact 1 are respectively connected to the two bridging portions 13, and each of the two connection bars 11 located at the front and rear side edges of the power contact 1 has only one side to which a plurality of the power contact arms 12 are connected, and a plurality of the power contact arms 12 connected to the same connection bar 11 are arranged in a row.
