Description

Technical Field

[0001] This utility model relates to an electrical connector. Background Technology

[0002] Traditional electrical connectors have a mating cavity and several spacers disposed within the mating cavity. A mating channel is formed between two adjacent spacers for the insertion of mating terminals. The surfaces of each spacer adjacent to the mating channel are vertically oriented planes. Thus, when the two sides of the spacer are planar, the creepage distance of the electric arc is short, and the plastic spacers are more likely to be broken down by the current. In addition, the structural strength of the ends of the spacers is also difficult to guarantee, making it difficult for traditional electrical connectors to meet the requirements of high-voltage environments.

[0003] In view of this, it is necessary to improve the existing electrical connectors to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an electrical connector with high structural strength.

[0005] To achieve the above-mentioned utility model objectives, this utility model provides an electrical connector, which includes an insulating body and a plurality of conductive terminals. The insulating body includes a mating portion forming a mating cavity and at least one spacer wall located within the mating cavity. The mating cavity is open forward and is divided by the spacer wall to form a plurality of terminal channels arranged in a transverse direction. The at least one spacer wall separates two adjacent terminal channels. The conductive terminals are fixed to the insulating body and their contact arms are exposed in the corresponding terminal channels. Each spacer wall has a first and a second wall surface arranged opposite to each other in the transverse direction, and at least one of the first and second wall surfaces is curved.

[0006] As a further improvement of this utility model, the portion where the partition wall connects to the docking portion is widened.

[0007] As a further improvement of this utility model, both the first and second wall surfaces are curved in the direction of being recessed in the middle away from their adjacent terminal channels, so that the width of the partition wall in the middle is smaller than the width of its top and / or bottom ends.

The top wall, the bottom wall and the pair of side walls surround to form the docking cavity. One end of the partition wall in the height direction is connected to the top wall or the bottom wall, and the height of the partition wall is greater than half the height of the docking cavity.

[0009] As a further improvement of this utility model, both the first and second wall surfaces include a first surface and a second surface that are arranged opposite to each other in the height direction, and both the first surface and the second surface are arranged at an angle to the vertical plane.

[0010] As a further improvement of this utility model, the docking part also has a snap-fit ​​part and a guide part protruding into the docking cavity, one of the top and bottom walls is connected to the partition wall, and the other is provided with the snap-fit ​​part and guide part protruding into the docking cavity.

[0011] As a further improvement of this utility model, the insulating body includes a base, a mating portion located on the front side of the base, and a plurality of extension walls extending rearward from the base. The plurality of extension walls are arranged in a transverse direction to connect with the circuit board. Each conductive terminal includes a contact arm, a fixing portion fixed in the base, and a welding portion exposed on the rear side of the base.

Each of the partition walls has a notch on both sides in the transverse direction. The notches include a first notch and a second notch with different extension lengths in the front-back direction.

[0014] As a further improvement of this utility model, the two ends of the partition wall in the height direction are respectively connected to the top wall and the bottom wall.

[0015] The beneficial effects of this utility model are as follows: The electrical connector of this utility model separates two adjacent terminal channels by at least one partition wall, and the contact arm of the conductive terminal is exposed in the corresponding terminal channel. Each partition wall has a first and a second wall surface arranged opposite to each other in the transverse direction.

[0023] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional modifications made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 7 The present invention is shown as a preferred embodiment of the electrical connector 100. 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 longitudinally elongated in the transverse direction.

[0025] For ease of explanation, when describing the electrical connector 100 below, the mating direction of the electrical connector 100 will be considered as the front-to-back direction, and the direction perpendicular to both the front-to-back and lateral directions will be considered as the height direction. In other embodiments, the insulating body may also be configured such that its dimension in the lateral direction is smaller than its dimension in the height direction.

[0026] Please refer to Figure 1 , Figures 3 to 7As shown, the insulating body 1 includes a mating portion 12 with a mating cavity 120 and at least one partition wall 13 located within the mating cavity 120. The mating cavity 120 is open to the front and is divided by the partition wall 13 to form a plurality of terminal channels 121 arranged in the 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 partition wall 13 has first and second wall surfaces 131 and 132 arranged opposite to each other in the transverse direction, and at least one of the first and second wall surfaces 131 and 132 is curved.

[0027] In this utility model, the electrical connector 100 increases the creepage distance of the electric arc by setting at least one of the first and second wall surfaces 131 and 132 of the spacer 13 into a curved shape, thereby reducing the probability of the plastic spacer 13 being broken down by a large current, thus achieving the effect of protecting the structure of the spacer 13 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. In this way, the bonding strength between the partition wall 13 and the docking portion 12 is increased, thereby increasing the structural strength of the insulating body 1.

[0029] The first and second wall surfaces 131 and 132 are both curved and recessed in the middle towards the direction away from their adjacent terminal channels 121, so that the width of the partition wall 13 in the middle is smaller than the width of its top and / or bottom ends. In the embodiment shown in this utility model, the width of the partition wall 13 in the middle is smaller than the width of its top and bottom ends, so that the partition wall 13 is narrowed in the middle and widened at both ends in the height direction, thereby increasing the structural strength of the partition wall 13 and increasing the creepage distance of the electric 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 disposed opposite each other in the height direction, and a pair of side walls 124 connecting the ends of the top wall 122 and the bottom wall 123. The top wall, bottom wall 122, 123 and the pair of side walls 124 surround to form the docking cavity 120. 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, two adjacent terminal channels 121 are effectively separated, thereby ensuring the independence between adjacent terminal channels 121, effectively ensuring the arc creep distance and preventing arcing.

[0031] The outermost terminal channel 121 in the lateral direction is formed by a spacer wall 13 and an adjacent side wall 124, while the inner terminal channel 121 is formed by two adjacent spacers 13.

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

[0033] The first surface 133 and the second surface 134 of the first wall 131 are symmetrically arranged in the height direction, and the first surface 133 and the second surface 134 of the second wall 132 are symmetrically arranged in the height direction.

[0034] like Figure 4 and Figure 5 As shown, in some embodiments of this utility model, some of the partition walls 13 are configured such that: the first surface 133 and the second surface 134 of the first wall surface 131 are both arc-shaped, and the first surface 133 and the second surface 134 are spaced apart in the height direction; the first wall surface 131 also includes a third surface 135 connecting the first surface 133 and the second surface 134; the first surface 133 and the second surface 134 of the second wall surface 131 are inclined planes, and the first surface 133 and the second surface 134 are angled; in other cases, some of the partition walls 13 are configured such that: the first surface 133 and the second surface 134 of the first and second wall surfaces 131 and 132 are both arc-shaped, and the first and second wall surfaces 131 and 132 each have a third surface 135 located between the first surface 133 and the second surface 134.

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

[0036] In addition, in the embodiments shown in this utility model, some of the first and second wall surfaces 131 and 132 of the partition walls 13 are symmetrically arranged in the lateral direction, while the first and second wall surfaces 131 and 132 of the other partition walls 13 are asymmetrically arranged in the lateral direction; in other embodiments, the electrical connector 100 may also set all the first and second wall surfaces 131 and 132 of the partition walls 13 to be symmetrical in the lateral direction or to be asymmetrical.

[0037] In the embodiment shown in this utility model, the docking part 12 also has a latching part 125 and a guide part 126 protruding into the docking cavity 120. One of the top and bottom walls 122 and 123 is connected to the partition wall 13, and the other is provided with the latching part 125 and the guide part 126 protruding into the docking cavity 120.

[0038] In this embodiment, a pair of latching portions 125 are disposed at the middle position of the docking cavity 120 in the lateral direction and are disposed adjacent to each other, and a plurality of guide portions 126 are disposed on both sides of the latching portions 125 in the lateral direction.

[0039] The insulating body 1 includes a base 14, a mating portion 12 located in front of the base 14, and a plurality of extension walls 15 extending rearward from the base 14. The plurality of extension walls 15 are arranged in a transverse direction to connect with a circuit board (not shown). The lower end face of the mating portion 12 is coplanar with the lower end face of the base 14, and the lower end face of the extension wall 15 protrudes below the lower end faces of the base 14 and the mating portion 12 to be inserted into the circuit board.

[0040] Each of the conductive terminals 2 includes the contact arm 21, the fixing part 23 held in the base 14, and the welding part 24 exposed on the rear side of the base 14. The welding part 24 is located between two adjacent extension walls 15, thereby increasing the creepage distance between the welding parts 24 of two adjacent conductive terminals 2, so that the electrical connector 100 can be used in high voltage environments.

[0041] Each of the spacer walls 13 extends forward from the front end face of the base 14, but does not extend forward to the front end face of the docking portion 12, that is, the spacer wall 13 is recessed within the docking cavity 120.

[0042] Please refer to Figure 1 , Figure 4 and Figure 6 As shown, in the first embodiment of this utility model, the docking part 12 further has a transverse wall 16 located in the docking cavity 120, the transverse wall 16 extends in the transverse direction, and the other end of the partition wall 13 in the height direction is connected to the transverse wall 16.

[0043] The docking part 12 also has notches 17 that divide the transverse wall 16 into several segments. Each partition wall 13 has a notch 17 on both sides in the transverse direction. The notches 17 include a first notch 171 and a second notch 172 with different extension lengths in the front-back direction.

[0044] The first notch 171 extends longer in the front-rear direction than the second notch 172 in the front-rear direction, and a second notch 172 is provided between every two adjacent first notches 171. Specifically, the front-rear extension length of the first notch 171 is the same as the front-rear depth of the mating cavity 120, that is, the first notch 171 extends rearward from the front end face of the transverse wall 16 to the front end face of the base 14. The second notch 172 is recessed rearward from the front end face of the transverse wall 16, and the recess depth of the second notch 172 in the front-rear direction is greater than half the front-rear extension length of the transverse wall 16.

[0045] In this invention, the transverse wall 16 is divided into several segments by the first notch 171 and the second notch 172. Each segment of the transverse wall 16 is provided with at least one second notch 172. Each segment of the transverse wall 16 is connected to at least one spacer wall 13. The other end of the spacer wall 13 is connected through the transverse wall 16, thereby increasing the structural strength of the end of the spacer wall 13, reducing the probability of the electrical connector 100 being broken down when transmitting large current, and improving the stability of the electrical connector 100.

[0046] like Figure 4As shown, among the several transverse wall segments 16, except for the two transverse wall segments 16 located on both sides in the transverse direction, each transverse wall segment 16 in the middle is connected to two corresponding partition walls 13 and is provided with a second notch 172; a transverse wall segment 16 located on one side in the transverse direction is connected to a partition wall 13 and is provided with a second notch 172 between the partition wall 13 and the side wall 124; a transverse wall segment 16 located on the other side in the transverse direction is connected to two partition walls 13 and is provided with two second notches 172.

[0047] In addition, in the second embodiment of this utility model, unlike the first embodiment, the two ends of the partition wall 13 in the height direction are connected to the top wall 122 and the bottom wall 123 respectively. That is, the insulating body 1 in this embodiment does not have a transverse wall extending in the lateral direction.

[0048] The electrical connector 100 of this invention separates two adjacent terminal channels 121 by at least one partition wall 13. The contact arm 21 of the conductive terminal 2 is exposed in the corresponding terminal channel 121. Each partition wall 13 has a first and a second wall surface 131 and 132 arranged opposite to each other in the transverse direction. At least one of the first and second wall surfaces 131 and 132 is curved. The curved first wall surface 131 and / or the second wall surface 132 is used to increase the creepage distance of the electric arc, reduce the probability of the plastic partition wall 13 being broken down by a large current, and achieve the effect of protecting the structure of the partition wall 13, thereby increasing the structural strength of the insulating body 1.
