[0023] The present invention will be described in detail below in conjunction with the embodiments shown in the accompanying drawings. However, the embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on the embodiments are all within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 7 The figure shows a preferred embodiment of the electrical connector 100 of the present invention. In this embodiment, the electrical connector 100 includes an insulating body 1 and a plurality of conductive terminals 2. The conductive terminals 2 are fixed in the insulating body 1. In this embodiment, the insulating body 1 is in a longitudinal shape extending in the transverse direction.

[0025] For the sake of convenience, the following description of the electrical connector 100 will be based on the fact that the mating direction of the electrical connector 100 is regarded as the front-to-back direction, and the direction perpendicular to the front-to-back direction and the transverse direction is regarded as the height direction. In other embodiments, the insulating body may also be configured such that the dimension in the transverse direction is smaller than the dimension in the height direction.

[0026] Please refer to Figure 1 , Figures 3 to 7 As shown, the insulating body 1 includes a docking portion 12 formed with a docking cavity 120 and at least one partition wall 13 located in the docking cavity 120. The docking cavity 120 is open to the front, and the docking cavity 120 is divided by the partition wall 13 to form a plurality of terminal channels 121 arranged in a transverse direction. The at least one partition wall 13 separates two adjacent terminal channels 121. The conductive terminal 2 is fixed to the insulating body 1 and its contact arm 21 is exposed in the corresponding terminal channel 121. Each of the partition walls 13 has a first wall 131 and a second wall 132 arranged opposite to each other in the transverse direction, and at least one of the first wall 131 and the second wall 132 is curved.

[0027] In the present invention, the electrical connector 100 increases the creepage distance of the arc by setting at least one of the first and second wall surfaces 131 and 132 of the partition wall 13 into a curved shape, thereby reducing the probability of the plastic partition wall 13 being broken down by a large current, thereby achieving the effect of protecting the partition wall 13 structure and increasing the structural strength of the insulating body 1.

[0028] Furthermore, in this embodiment, the portion where the partition wall 13 is connected to the docking portion 12 is widened, that is, the width of the connection portion between the partition wall 13 and the docking portion 12 in the lateral direction is greater than the width away from the connection portion, thereby increasing the bonding strength between the partition wall 13 and the docking portion 12, thereby increasing the structural strength of the insulating body 1.

[0029] The first and second wall surfaces 131 and 132 are both in a curved shape with the middle portion concave in a direction away from the adjacent terminal channel 121, so that the width of the partition wall 13 in the middle portion is smaller than the width of the top and / or bottom end thereof. In the embodiment shown in the present invention, the width of the partition wall 13 in the middle portion is smaller than the width of the top and bottom ends thereof, so that the middle portion of the partition wall 13 in the height direction is narrowed and the two ends are widened, thereby increasing the structural strength of the partition wall 13 and increasing the creepage distance of the arc, thereby improving the overall structural strength of the insulating body 1.

[0030] Specifically, the docking portion 12 includes a top wall 122 and a bottom wall 123 that are arranged opposite to each other in the height direction, and a pair of side walls 124 that connect the ends of the top wall 122 and the bottom wall 123.

One end of the partition wall 13 in the height direction is connected to the top wall 122 or the bottom wall 123, and the height of the partition wall 13 is greater than half the height of the docking cavity 120. In this way, by making the extension height of the partition wall 13 in the height direction greater than half the height of the docking cavity 120, the two adjacent terminal channels 121 are effectively separated, thereby ensuring that the adjacent terminal channels 121 are independent of each other, effectively ensuring the creeping distance of the arc, and avoiding misfire.

[0031] The terminal passage 121 located at the outermost side in the lateral direction is formed by spacing between one of the partition walls 13 and the side wall 124 adjacent thereto, and the terminal passage 121 located at the inner side is formed by spacing between two adjacent partition walls 13 .

[0032] The first and second walls 131 , 132 each include a first surface 133 and a second surface 134 that are disposed opposite to each other in a height direction, and the first surface 133 and the second surface 134 are disposed at an angle to a vertical plane.

[0035] In other embodiments of the present invention, the first surface 133 and the second surface 134 of the first and second walls 131, 132 of all partition walls 13 may be arranged to be arc-shaped, or the first surface 133 and the second surface 134 of the first and second walls 131, 132 of all partition walls 13 may be arranged to be inclined planes, and the first surface 133 and the second surface 134 of the same wall may be arranged at an angle.

[0036] In addition, in the embodiment shown in the present invention, the first and second wall surfaces 131, 132 of a portion of the partition walls 13 are symmetrically arranged in the transverse direction, and the first and second wall surfaces 131, 132 of another portion of the partition walls 13 are asymmetrically arranged in the transverse direction; in other embodiments, the electrical connector 100 may also set the first and second wall surfaces 131, 132 of all the partition walls 13 to be symmetrical structures in the transverse direction or to be asymmetrical structures.

Specifically, the extension length of the first notch 171 in the front-to-back direction is the same as the depth of the docking cavity 120 in the front-to-back direction, that is, the first notch 171 extends backward from the front end surface of the transverse wall 16 to the front end surface of the base 14. The second notch 172 is formed by being recessed backward from the front end surface of the transverse wall 16, and the recessed depth of the second notch 172 in the front-to-back direction is greater than half of the extension length of the transverse wall 16 in the front-to-back direction.
