Description

[Technical field]

[0001] The invention relates to a plug connector, in particular to a plug connector for transmitting large current. [Background technology]

[0002] Modern transportation vehicles are bound to experience rainy weather, so the internal electrical connectors will be treated with corresponding waterproofing or drainage to protect them from the influence of rain and avoid short circuit of the electrical connectors; taking electric bicycles as an example, they use a detachable external power supply for riding and can also be ridden by foot with the power supply removed. When the power supply is supplied, the electrical connector should have a good waterproof function, and when riding after the power supply is removed, the electrical connector is in an exposed state, so an electric connector with a drainage function is needed to prevent rainwater from accumulating in the electrical connector or even seeping into the interior of the electrical connector; and the existing electrical connectors are only designed to be waterproof for the general situation of the male and female ends in combination, but do not take into account the situation where the male and female ends are exposed after being separated.

[0003] Therefore, it is necessary to provide a plug connector with a drainage function. [Summary of the invention]

[0004] The technical problem to be solved by the present invention is to provide a plug connector with a drainage structure.

[0021] See also Figures 1 to 10 , which discloses a plug connector 100 and a socket connector 200 mating therewith of the present invention.

[0022] Ginseng Figures 3 to 8 The plug connector 100 includes an insulating body 1 and a conductive terminal 2 fixed to the insulating body 1. The conductive terminal 2 includes a fixing portion 22, a pin 23 extending from one end of the fixing portion 22 to the insulating body 1, and a contact portion 21 extending from the other end of the fixing portion 22. The contact portion 21 is sheet-shaped, and the contact portions 21 of each conductive terminal 2 are parallel to each other. The insulating body 1 includes a base 10 and a longitudinal island portion 11 protruding from the base 10, and the island portion 11 defines a longitudinal direction L. The insulating body 1 includes a side wall 12, and the side wall 12 is formed by extending vertically from the first mating surface 101. The base 10 has a first mating surface 101 located at its front end, and the island portion 11 has a second mating surface 111 located at its front end, and the second mating surface 111 is located in front of the first mating surface 101.

[0023] The plug connector 100 defines a first direction V and a second direction X perpendicular to the longitudinal direction. The first and second directions are perpendicular to each other, and the first direction V is perpendicular to the side wall 12. The conductive terminal 2 includes a first terminal 24, a second terminal 25, and a third terminal 26. The contact portions 21 of the first and third terminals 24 and 26 protrude from the first mating surface 101, and the contact portion 21 of the second terminal 25 protrudes from the second mating surface 111. Figure 2 It can be seen that the contact portion 24 of the first terminal 24 is located at one side of the island 11, and the contact portion 21 of the third terminal 26 is located at both ends of the island 11. Figure 5 and Figure 8 The other side of the island 11 is connected to the side wall 12 .

[0024] An edge of the contact portion 21 of the third terminal 26 is embedded in the side wall 12. The edge of the second terminal 25 adjacent to the side wall 12 is spaced a certain distance from the side wall 12 to ensure a smooth drainage channel in the longitudinal direction without being blocked by the second terminal 25. The contact portion 21 of the third terminal 26 is provided with a notch 261, which is located at the junction of the side wall 12 and the first mating surface 101 to provide a drainage function.

[0025] There are multiple first and second terminals 24 and 25, and the second terminals 25 are arranged in a row along the longitudinal direction L of the island 11. In this embodiment, the number of the first and second terminals 24 and 25 is four. The first terminals 24 are arranged in a row parallel to the second terminals 25, and the first terminals 24 and the second terminals 25 are aligned one by one in the first direction V. There are two third terminals 26 and they are located at both ends of the island 11 along the longitudinal direction and are spaced a certain distance from the side of the island 11.

[0026] In the second direction X, the second mating surface 111 is inclined to increase the drainage effect, and the side adjacent to the first terminal 24 is the lower side. Figure 8 As shown, the angle between the second butting surface 111 and the side wall 12 is an obtuse angle.

[0027] In the first direction V, the width of the contact portion 21 of the third terminal 26 is greater than the width of the contact portions 21 of the first and second terminals 24 and 25, and the edge 241 of the contact portion 21 of the first terminal 24 protrudes out of the edge 261 corresponding to the contact portion 21 of the third terminal 26. In the second direction, the length of the first terminal 24 is greater than the length of the second terminal 25, and the edge 251 of the contact portion 21 of the second terminal 25 protrudes out of the edge 262 corresponding to the contact portion 21 of the third terminal 26. The island portion 11 covers the root of the second terminal 25 located in front of the first mating surface 101 to increase the retention force of the second terminal 25 and prevent water from seeping into the connector.

[0028] In this embodiment, the base 10 has three steps along the second direction, namely the first step 102, the second step 103 and the third step 104. The front end surface of the first step 102 is the first mating surface 101. The plug connector 100 also includes a panel 5 attached to the front end surface of the second step 102.

[0029] Ginseng Figures 8 to 10, which is the socket connector 200 of the present invention, includes a second insulating body 3 and socket terminals 4 held therein. The second insulating body 3 includes a second base portion 31 and a semi-open receiving space 32 extending from the second base portion 31. The receiving space 32 is formed by enclosing three second side walls 33 extending from the second base portion 31 and is arranged in a U-shape. The socket connector 200 further includes a fastener 7 mounted to the second base portion 31 and a panel 6 attached to the front end face of the second base portion 31. A plurality of partition plates 34 extending from the second substrate 31 are further provided in the receiving space 32. The plurality of partition plates 34 divide the receiving space 32 into a plurality of sub-receiving spaces 321. A corresponding socket terminal 4 is held in each sub-receiving space 321 for mating with the conductive terminal 2 of the plug connector 100. The front end faces of the plurality of partition plates 34 are provided with recessed portions 341 and are combined with the sub-receiving spaces 321 to form a receiving portion 35 for receiving the island portion 11 of the plug connector 100. The three second side walls 33 of the socket connector 200 and one side wall 12 of the plug connector 100 form a closed docking space to prevent external rainwater from entering the docking space, and the three second side walls 33 arranged in a U-shape surround the first step 102 to increase the sealing performance, as can be seen from Figure 2 It can be seen.
