DETAILED DESCRIPTION

[0010] The following detailed description will further illustrate the present application in connection with the above-mentioned drawings.

[0011] Referring to the drawings, Figures 1-10 The present application is a power connector combination. The power connector 100 is fixed on the power panel 500, and is used to dock the power output interface in the PSU (power supply unit), such as the power card panel, Figure 2 A part of the power card panel 600 is shown schematically. The surface of the power card panel is provided with a conductive gold finger, which transmits the current of the power card panel to the power connector 100, and then to the power panel 200, and finally outputs from the output side power connector on the other side of the power panel 200. In this embodiment, the power panel 200 can be a copper bus, an aluminum bus, or other forms, such as a small circuit board.

[0012] The power connector assembly in the embodiment comprises a power connector 100, a power board 500, and a first fixing member 41 and a second fixing member 42. The power connector 100 is provided with a mating direction X-X, and comprises an insulating body 10 and a power terminal 20. For the convenience of description, the power connector 100 defines a mating direction X, a first direction Y and a second direction Z perpendicular to each other, and the front side of the power connector 100 is the side of the power connector 100 to be inserted into an external element such as a power card, and the opposite side is the rear side. In the embodiment, a common installation mode of the power connector 100 is shown, the mating direction X of the power connector 100 is the front-rear direction, the first direction Y-Y is the up-down direction, and the second direction Z-Z is the left-right direction. The insulating body 10 is provided with a mating slot 11 penetrating forward along the mating direction X-X, a slot inner bottom 110 facing forward, and a mounting surface 12 opposite to the slot inner bottom 110, and the mounting surface 12 is the side of the power connector 100 to be mounted with the power board 500. The power terminal 20 is fixed to the insulating body 10, and comprises a base 21 and at least one elastic arm 23 extending forward, the elastic arm 23 is provided with a contact portion 231 protruding into the mating slot 11, and the base 21 is arranged on the mounting surface 12. When the power connector 100 is mounted on the power board 500, the power terminal 20 is electrically connected with the power board 500, and the power card 600 can be abutted with the contact portion 231 after being inserted into the mating slot 11, so as to achieve electrical connection, thereby transmitting the current of the power card to the power board 500.

[0013] In the embodiment, the first fixing member 41 is fixedly connected with the base 21, and the second fixing member 42 is fixedly connected with the power board 500. Figure 4 As shown in the figure, the first fixing member 41 is fixedly connected with the base 21. The power board 500 is provided with a long slot 51, and the second fixing member 42 passes through the long slot 51 and is locked with the first fixing member 41, so as to mount the power connector 100 on the power board 500, and the size of the long slot 51 is greater than that of the second fixing member 42, so that the second fixing member can slide in the long slot 51. Due to the assembly tolerance of the power connector and the power board, or the assembly tolerance of the PSU itself, when the power card 600 is inserted into the mating slot 11, it is inevitable to deviate from the center position of the mating slot 11, and the power card will hit the power connector, especially the insulating body 10 made of insulating materials such as plastic, which is more easily damaged by impact. In the embodiment, the power connector 100 is allowed to float by sliding the second fixing member 42, so as to adjust the position of the insulating body 10 in real time, and avoid the impact damage of the power card to the insulating body 10.

[0014] More than that, the insulation body in the application has no floating relative to the power terminal, that is, there is no floating connection in the whole power connector, and the power connector is relatively floating relative to the power panel 500 through the second fixing member 42. In this way, the situation that the insulation body and the power terminal are separated from each other due to the floating between the insulation body and the power terminal is avoided. Of course, when the conditions permit, the insulation body can be arranged to have slight floating relative to the power terminal, but the sliding of the power connector relative to the power panel plays a major floating role.

[0015] In the embodiment, the power terminal 20 is arranged on the insulation body 10, and the power terminal 20 is arranged on the insulation body 10. Figures 4-6 As shown in the figure, the insulation body 10 includes two side walls 13 arranged along the first direction Y-Y, and the power terminal 20 includes a plurality of elastic arms 23 arranged on each side wall 13 along the second direction Z-Z. The long slot 51 extends along the first direction Y-Y. When the power card plate is inserted into the docking slot 11, it is inevitable to deviate from the central position of the docking slot 11, especially in the up-down direction in the embodiment, the power card plate will hit the power connector, especially the insulation body 10 made of plastic or other insulating materials. In the application, the power connector is allowed to float in the first direction Y-Y by the second fixing member, which can adjust the position of the insulation body in real time and avoid the damage of the power card plate to the insulation body.

In the embodiment, the first fixing member 41 is similar to the nut structure, and the second fixing member 42 is similar to the bolt structure, which can be rotatably assembled with the first fixing member 41, thereby simplifying the locking process of the first and second fixing members. The nut structure of the first fixing member can occupy as little space as possible in the power connector, thereby avoiding damage to the insulation body 10. Preferably, the mounting surface 12 of the insulation body is provided with a recessed avoiding recess 151 corresponding to the threaded hole 411, so as to avoid the insertion of the column portion 422.

The power connector comprises two clamping members 30 fixed on the corresponding fixing parts 22 and provided with clamping tabs 311 extending backward and outward, which are clamped on the insulating body to fix the power terminal in the insulating body. In the embodiment, in combination with Figures 9-10 As shown, the clamping plate 31 in the clamping member is fixed on the fixing part 22 by the riveting column 32, and the clamping tab 311 is punched out of the clamping plate 31.

[0020] In the embodiment, in combination with Figure 5 As shown, the insulating body is provided with terminal grooves 14 on the inner side of the side wall 13 respectively, the terminal grooves 14 penetrate through along the direction of abutment, and the crossbeam 15 is formed between the two terminal grooves 14, and the avoiding recess 151 is arranged on the crossbeam 15. The two groups of elastic arms 23 of the power terminal are inserted into the corresponding terminal grooves 14 respectively, until the clamping tabs 311 of the corresponding clamping members 30 are inclined and pressed backward on the clamping grooves 141 on the inner wall of the terminal grooves 14, so that the power terminal is limited to be unable to be separated backward from the insulating body.

[0021] In the embodiment, in combination with Figures 6-10 As shown, the power terminal 20 comprises two inner terminal pieces 25 and two outer terminal pieces 26, each inner terminal piece and outer terminal piece comprises a sub-base 251, 261, a sub-fixing part 252, 262 bent forward from the corresponding sub-base, and a sub-elastic arm 253, 263 extending from the sub-fixing part, the sub-fixing parts 251, 261 of the inner terminal piece and the corresponding outer terminal piece are stacked together along the first direction Y-Y, and the sub-bases 251, 261 are arranged along the second direction Z-Z. In combination with Figures 6-10As shown, the sub-base 251 of the inner terminal piece located at one side wall and the sub-base 261A of the outer terminal piece located at the other side wall are stacked with each other to form a stacked sub-base; the sub-base 261 of the outer terminal piece located at one side wall and the sub-base 261A of the inner terminal piece located at the other side wall are stacked with each other to form another stacked sub-base. The two stacked sub-bases are respectively provided with the fixing hole 221. In this way, the power terminal composed of the four terminal pieces can transmit large current, and the stacked sub-bases can enhance the strength of the whole base of the power terminal and strengthen the stable holding of the power terminal and the first fixing member.
