DETAILED DESCRIPTION

[0033] In view of this, the core of the utility model is to design a power connector, which has a small number of parts, is easy to assemble, and can ensure smooth and secure insertion of the pins. Another core of the utility model is to design an electric vehicle charging pile with the above power connector.

[0034] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] Please refer to the attached Figure 1 -Attached Figure 6 The utility model discloses a power connector, comprising a first shell 1, a second shell 2 and a plurality of conductive members 3. The first shell 1 and the second shell 2 are butted together along a first direction to form a complete shell. The conductive member 3 is arranged in the shell. The conductive member 3 comprises a tube 31 and a column 32 connected to each other. The column 32 extends from the second shell 2 to be welded to the power distribution plate on the power distributor 5. The first direction can be attached Figure 3 The x-axis direction in .

[0036] The first shell 1 includes a first panel 11, a sleeve 12 and a claw 14. The first panel 11 is perpendicular to the first direction. The sleeve 12 is arranged on the outer side of the first panel 11, and the sleeve 12 extends along the first direction. The pipe 31 is sleeved in the sleeve 12. The end of the sleeve 12 away from the first panel 11 is the distal end, and a stop edge 121 is arranged in the port of the distal end, and the stop edge 121 protrudes from the tube wall of the sleeve 12 to the center of the sleeve 12. The stop edge 121 is used to block the pipe 31 inside the sleeve 12. Preferably, the stop edge 121 is integrally formed with the sleeve 12.

[0037] An insertion hole is formed on the inner side of the first panel 11, and the insertion hole is communicated with the sleeve 12. The pipe 31 is inserted into the sleeve 12 through the insertion hole. A barb 14 is provided on the inner side of the first panel 11 and near the insertion hole. The root of the barb 14 is fixedly connected to the first panel 11, and the head of the barb 14 protrudes toward the center of the sleeve 12. Preferably, the barb 14 is integrally formed with the first panel 11.

[0038] The diameter of the pipe 31 is larger than the diameter of the column 32, and an annular blind end is formed around the end of the column 32 on the end surface of the pipe 31 connected to the column 32. The head of the claw 14 abuts against the annular blind end 312, so that the pipe 31 abuts against the retaining edge 121. In this way, the positioning of the pipe 31, or the entire conductive member 3, is achieved.

[0039] When assembling the conductive member 3, it is only necessary to open the inverted claw 14 outwards so that the pipe 31 is inserted into the sleeve 12 from the insertion hole, and then the inverted claw 14 is loosened, and the head of the inverted claw 14 presses the pipe 31 against the stop edge 121 through the annular blind end 312, thereby realizing the positioning of the conductive member 3. The inverted claw 14 and the stop edge 121 used for positioning the pipe 31 in the utility model are respectively connected to the first panel 11 and the sleeve 12, and it is not necessary to assemble the inverted claw 14 and the stop edge 121 during assembly, so the power connector in the utility model has fewer parts and is easy to assemble, and the abutment force of the inverted claw 14 and the stop edge 121 on the pipe 31 can ensure that the conductive member 3 is firmly positioned.

[0040] The inverted claws 14 are arranged in pairs, and each pair of inverted claws 14 is arranged symmetrically about the central axis of the sleeve 12. The symmetrically arranged pair of inverted claws 14 can form a balanced and firm abutment force on the pipe 31, thereby further ensuring that the pipe 31 is firmly positioned. In a specific implementation of the utility model, a pair of inverted claws 14 is provided.

[0041] Along the circumference of the insertion hole, a positioning plate 16 is provided between two adjacent claws 14, and the positioning plate 16 extends along the first direction. The side of the positioning plate 16 facing the central axis of the sleeve 12 is an arc surface, and the arc surface matches the outer surface of the pipe 31. In this way, the positioning plate 16 positions the pipe 31, preventing the pipe 31 from tilting toward the positioning plate 16, thereby further ensuring that the conductive member 3 is firmly positioned.

[0042] Please refer to the attached Figure 5 A pair of inverted claws 14 and a pair of positioning plates 16 are arranged around the insertion hole. When inserting the pipe 31 into the sleeve 12, it is only necessary to pry the two inverted claws 14 apart outwards.

[0043] Please refer to the attached Figure 1 , Attachment Figure 3 , Attachment Figure 4 A pair of retaining edges 121 are provided in the port at the distal end of the sleeve 12 , and the pair of retaining edges 121 are symmetrically arranged about the central axis of the sleeve 12 .

[0044] In addition, a conductive spring is disposed in the tube 31, and the conductive spring contacts the inserted pins by pressing, thereby ensuring effective contact between the pins and the tube 31, providing a low impedance path for large current. The conductive spring is further preferably a conductive gold-plated spring.

[0045] The end of the pipe fitting 31 connected to the column 32 is a completely blind end formed by the annular blind end 312 and the end of the column 32. When inserting a pin into the pipe fitting 31 through the insertion hole, air pressure will be formed in the tube cavity, causing the pin to be unable to be plugged in. To solve this problem, the specific embodiment of the utility model is provided with an air hole 311 on the tube wall of the pipe fitting 31, and the air hole 311 connects the outside world and the tube cavity of the pipe fitting 31. In this way, when inserting a pin into the tube cavity of the pipe fitting 31, the gas in the tube cavity can be discharged from the air hole 311, thereby ensuring that the pin is plugged in.

[0046] Please refer to the attached Figure 3 , Attachment Figure 4 , Attachment Figure 5 The pillar 32 in the utility model includes a first pillar part and a second pillar part connected to each other. The first pillar part and the second pillar part form an angle part at the connection, and the first connection part and the second connection part form an "L" shape.

[0047] Please refer to the attached Figure 2 , Attachment Figure 3The second shell 2 includes two second side panels 22 and a second panel 21 that are arranged opposite to each other. The second panel 21 is perpendicular to the first direction. The two second side panels 22 are parallel to the first direction. A limiting hole 23 is provided on one of the second side panels 22, and the limiting hole 23 is provided for the second column part to pass through so as to be welded with the power distribution board. The limiting hole 23 forms a limit for the column part 32, effectively preventing the conductive part 3 from rotating. A limiting cover plate 24 is provided near the other second side panel 22, and a side of the limiting cover plate 24 facing the limiting hole 23 is a curved surface, which matches the outer surface of the bent corner part, and the limiting cover plate 24 abuts against the bent corner part through the curved surface to further position the conductive part 3.

[0048] The first panel 11 extends along a second direction perpendicular to the first direction, that is, the length direction of the first panel 11 is perpendicular to the first direction. Figure 3 A plurality of sleeves 12 are arranged at intervals along the length direction of the first panel 11, so that a row of pins can be inserted into the conductive member 31 in a sleeve 12. Each sleeve 12 is provided with a conductive member 3, a pair of stop edges 121, a pair of inverted claws 14, a pair of positioning plates 16, a limit cover plate 24 and a limit hole 23.

[0049] In a specific implementation of the present invention, the pipe 31 and the L-shaped column 32 are integrally cast. In addition, the conductive member 3 is preferably made of red copper and is tin-plated or matte-tin treated.

[0050] Please refer to the attached Figure 3 and attached Figure 4 The limiting hole 23 extends to the edge of the corresponding second side plate 22 and forms a through opening at the edge of the corresponding second side plate 22. During the installation process, the pipe 31 of the conductive member 3 is first installed in the sleeve 12 of the first shell member 1, and then the second shell member 2 is buckled. During the buckling process, the second column member enters the limiting hole 23 through the through opening, thereby significantly reducing the difficulty of installation.

[0051] The first shell 1 and the second shell 2 may be connected by a clip. Specifically, a clip is provided on one of the first shell 1 and the second shell 2, and a slot connected with the clip is provided on the other shell. When the first shell 1 and the second shell 2 are buckled together, the clip is inserted into the slot, thereby realizing the connection between the first shell 1 and the second shell 2.

[0052] In the specific implementation of this utility model, please refer to the attached Figure 3 , Attachment Figure 4 And attached Figure 5, the first shell 1 and the second shell 2 are connected by screws 4. Specifically, a first internally threaded column 15 is provided on the first panel 11 of the first shell 1, and the first internally threaded column 15 protrudes in the direction of the second panel 21. Correspondingly, a second internally threaded column 25 is provided on the second panel 21, and the second internally threaded column 25 protrudes in the direction of the first panel 11. After the first shell 1 and the second shell 2 are buckled with each other, the first internally threaded column 15 and the second internally threaded column 25 are connected to form an internally threaded column group. The screw 4 is screwed into the internally threaded column group.

[0053] From the above description, it can be known that the sleeves 12 are arranged in a plurality along the length direction of the first panel 11, and the conductive members 3 are also arranged in a plurality along the length direction of the first panel 11. A gap is formed between two adjacent conductive members 3, and the internal thread column group is located in the gap.

[0054] The arrangement of the first internal thread column 15 and the second internal thread column 25 not only ensures the length of the internal thread to ensure a firm screw connection with the screw 4, thereby improving the firmness of the connection between the first shell 1 and the second shell 2, but also hides the screw 4 inside to prevent the screw 4 from contacting the conductive member 3. In addition, the internal thread column group is located between two adjacent conductive members 3, and the internal thread column group ensures effective insulation between the two adjacent conductive members 3.

[0055] Please refer to the attached Figure 3 and attached Figure 4 In the specific embodiment of the utility model, three groups of internal threaded column groups are arranged. In the length direction of the second panel 21, or in other words, in the length direction of the entire shell, two groups of internal threaded column groups are distributed at both ends of the entire shell, and the third group of internal threaded column groups is arranged in the middle of the entire shell. That is, both ends and the middle of the entire shell are locked by screws 4, so that the overall firmness of the shell can be ensured.

[0056] In order to achieve precise docking of the first internal thread column 15 and the second internal thread column 25 during the docking of the second shell 2 and the first shell 1, the specific embodiment of the utility model is designed as follows: a second positioning member 26 arranged along the length direction thereof and protruding toward the first panel 11 is provided on the second panel 21, and a first positioning member 13 protruding toward the second panel 21 is provided on the first panel 11. The first positioning member 13 and the second positioning member 26 are plugged into each other to form a positioning member group. It can be seen from the above description that if the internal thread column group is located between two adjacent conductive members 3, then the positioning member group is located between another two adjacent conductive members 3. In other words, if a gap is formed between two adjacent conductive members 3, then the internal thread column group and the positioning member group are located in different gaps.

[0057] In addition to the guiding and positioning functions, the positioning member group also has the function of effectively insulating two adjacent conductive members 3 .

[0058] The second positioning member 26 may be a column, and the first positioning member 13 may be a hole. The column is inserted into the positioning hole of the hole.

[0059] Please refer to the attached Figure 4 A total of six conductive members 3, six sleeves 12, six limiting holes 23 and six limiting cover plates 24, three groups of internal thread column groups and two groups of positioning member groups are provided.

[0060] Please refer to the attached Figure 7 and attached Figure 8 The utility model also discloses an electric vehicle charging pile, including a power distributor 5, a back plate 6 and a power connector. The power connector is arranged on the power distributor 5, and the end of the column 32 in the power connector is welded to the power distribution board in the power distributor 5. A plug pin is arranged on the back plate 6, and the plug pin can be inserted into the pipe 31 of the power connector. In particular, the power connector is any one of the above-mentioned power connectors, and the above-mentioned power connector has the above-mentioned effects. The electric vehicle charging pile having the above-mentioned power connector also has the above-mentioned effects, so it will not be repeated here.

[0061] Please refer to the attached Figure 3 , Attachment Figure 4 And attached Figure 6 The first shell 1 includes two first side panels arranged opposite to each other, and the first side panels are parallel to the first direction. A positioning hole column 17 is provided on one of the first side panels, and the positioning hole column 17 protrudes in the same direction as the sleeve 12, and the positioning column hole 17 is located at one end of the length direction of the corresponding first side panel, and a positioning column adapted to the positioning hole column 17 is provided on the back panel 6. Two power connectors arranged side by side are provided on the power distributor 5, and the positioning hole columns 17 in the two power connectors are diagonally distributed. In this way, when the pins on the back panel 6 are inserted into the sleeve 12 of the power connector, the cooperation between the diagonally distributed positioning hole columns 17 and the positioning columns on the back panel 6 can ensure that all the pins are accurately inserted into the corresponding pipe fittings 31.
