[0028] In order to explain the technical content and structural features of the present invention in detail, the following is a further description in conjunction with the embodiments and the accompanying drawings.

[0029] See also Figure 1 、 Figure 2 and Figure 6 The anti-short-circuit connector 100 of the present invention includes a first connector 10 and a second connector 20 , and the second connector 20 is plugged into and matched with the first connector 10 to meet the plugging and unplugging operation requirements between the second connector 20 and the first connector 10 .

[0030] Recombination Figure 3 The first connector 10 includes a first insulating body 11 having an inserting cavity 11a and a plurality of first terminals 12 mounted on the first insulating body 11 and separated from each other. A protruding partition structure 13 is provided in the inserting cavity 11a. The partition structure 13 divides the inserting cavity 11a into a corresponding number of partition areas 111. Each first terminal 12 is located in a corresponding partition area 111. Optionally, Figures 2 to 5As an example, the number of the first terminals 12 is five, and correspondingly, the number of the separation areas 111 is also five, so as to meet the need that each first terminal 12 is located in a corresponding separation area 111, and each first terminal 12 is arranged in a suspended manner in its corresponding separation area 111; obviously, according to actual needs, the number of the first terminals 12 and the separation areas 111 can also be two, three or four, so it is not limited to Figures 2 to 5 Limits shown.

[0031] The second connector 20 includes a second insulating body 21 having a plug connector 21a and a plurality of second terminals 22 mounted on the second insulating body 21 and spaced apart from each other. The plug connector 21a is provided with a plurality of spaced-apart partitioning grooves 211 that cooperate with the partitioning structure 13. The partitioning grooves 211 separate the plug connector 21a into a number of plug blocks 212 equal to the number of partitioning areas 111. Each second terminal 22 extends into a corresponding plug block 212 and is exposed externally from the plug block 212, ensuring electrical contact between the second terminal 22 and the first terminal 12 during the mating process between the first connector 10 and the second connector 20. More specifically, as follows:

[0032] like Figures 2 to 4 As shown, as an example, all the first terminals 12 are arranged on the first insulating body 11 to form a first terminal row 10a to meet the flat design requirements of the first insulating body 11; the arrangement direction of the first terminal row 10a (see arrow B) intersects with the insertion direction of the plug cavity 11a (see arrow A in the opposite direction). Optionally, Figure 2 As an example, the arrangement direction of the first terminal row 10a is perpendicular to the insertion direction of the plug-in cavity 11a to better ensure the reliability of the contact between the first terminal 12 and the second terminal 22. In addition, a partition structure 13 is arranged between two adjacent first terminals 12 to better meet the requirement that each partition structure 13 blocks a small amount of rainwater from flowing between the two adjacent first terminals 12 in the arrangement direction of the first terminal row 10a. Specifically, Figures 2 to 5 In the example, the partition structure 13 is arranged horizontally, and the horizontal direction of the partition structure 13 (as indicated by the arrow C) intersects with the arrangement direction of the first terminal row 10a, for example but not limited to vertical intersection; such a design can simplify the structure of the partition structure 13; in addition, the partition structure 13, the cavity bottom wall 112 of the plug-in cavity 11a and the two opposite cavity side walls 113 of the plug-in cavity 11a together form an integrated structure to simplify the manufacturing process of the first insulating body 11, and completely prevent a small amount of rainwater that penetrates into the partition area 111 from flowing between the partition areas 111; in addition, the partition structure 13 is also retracted relative to the cavity opening 1111 of the plug-in cavity 11a, that is, the partition structure 13 does not protrude from the plug-in cavity 11a, which can reduce the groove depth of the partition groove 211. More specifically, in Figure 2 、 Figure 3 and Figure 5 In the embodiment, as an example, the separation structure 13 is in a plate shape to simplify the mold structure for injection molding the first insulating body 11 and also play a reinforcing role.

[0033] like Figures 2 to 5 As shown, as an example, the first insulating body 11 further has a water leakage hole 11b, each partition 111 is configured with a water leakage hole 11b, and each partition 111 is connected to the corresponding water leakage hole 11b, so that a small amount of rainwater that penetrates into the partition 111 can be drained outwards by means of the water leakage hole 11b, thereby having a better effect of preventing short circuit and electrolysis. Figures 2 to 5 As an example, the water leakage hole 11b penetrates the bottom wall 112 of the plug-in cavity 11a, so that a small amount of rainwater that penetrates into the partition area 111 is discharged more thoroughly; in addition, each partition area 111 corresponds to a plurality of water leakage holes 11b, and the plurality of water leakage holes 11b are arranged at intervals; for example, Figures 4 and 5 As an example, the number of leakage holes 11b corresponding to each partition 111 is eight, and the eight leakage holes 11b are arranged around the corresponding first terminal 12. Obviously, according to actual needs, the number of leakage holes 11b corresponding to each partition 111 can also be two, three, four, five, etc., so it is not limited to the above. Figures 4 and 5 Therefore, by virtue of the number of leak holes 11b corresponding to each partition 111 being multiple, the leak holes 11b protect the first terminal 12 from surrounding the first terminal 12, and maximally block the small amount of rainwater that penetrates into the partition 111 from flowing to the first terminal 12 corresponding to the partition 111. For example, Figure 2 As an example, the first terminal 12 is arranged on the first insulating body 11 in a straight line, and its extension direction is parallel to the insertion direction of the plug cavity 11a. Figure 2 shown.

[0034] Among them, Figure 1 and 2 As an example, the first insulating body 11 also has a first lug 11c protruding laterally outward, and the first lug 11c is provided with mounting holes 114 around it. Correspondingly, the second insulating body 21 also has a second lug 21b protruding laterally outward, and the second lug 21b is provided with a matching hole 213 that cooperates with the mounting hole 114. With the help of the matching of the mounting hole 114 and the matching hole 213, it is convenient for the operator to use the fastening assembly to fasten the first connector 10 and the second connector 20, so that the first connector 10 and the second connector 20 are more stable after being plugged in. For example, the fastening assembly can be an assembly composed of bolts and nuts, but is not limited to this. It should be noted that the lateral direction here refers to the direction perpendicular to the insertion direction of the plug-in cavity 11a.

[0035] like Figure 6 As shown, each plug block 212 is provided with a plurality of slot structures 214 that are spaced apart from each other and arranged around the second terminals 22 on the plug block 212. Figure 6 As an example, the number of slot structures 214 on each plug block 212 is four. Obviously, the number of slot structures 214 on each plug block 212 may be two, three, or five depending on actual needs. Figure 6 The slot structure 214 is used to make the second insulating body 21 a non-solid structure, ensuring a uniform wall thickness within the second insulating body 21 and preventing severe shrinkage during the cooling of the second insulating body 21. It should be noted that the slot structure 214 can be configured as either a through-hole or a non-through-hole structure in the direction of insertion of the plug connector 21a.

[0036] like Figure 7 As shown, it is Figure 4 The first connector 10 shown is deformed. Figure 7 In the embodiment, the first terminals 12 in the first connector 10 are arranged in two first terminal rows 10a. The arrangement direction of the first terminal rows 10a (as indicated by arrow B) intersects with the insertion direction of the insertion cavity 11a, for example, but not limited to, perpendicularly. In addition, the number of first terminals 12 in each row is five; obviously, according to actual needs, the number of first terminals 12 in the same row can also be other, so it is not limited to the above. Figure 7 The following are the limits shown. Figure 4 In the embodiment, the first terminals 12 are arranged to form only one first terminal row 10a.

[0037] At the same time, Figure 7 In the embodiment, since the first terminals 12 are arranged into two first terminal rows 10a, the partition structure 13 includes first partition structures 131 and second partition structures 132 arranged in a cross shape. The first partition structure 131 extends along the arrangement direction of the first terminal rows 10a. A first partition structure 131 is arranged between two adjacent first terminal rows 10a; and a second partition structure 132 is arranged between two adjacent first terminals 12 in the same first terminal row 10a. Figure 7 shown.

[0038] And Figure 4 In the embodiment, the partition structure 13 is not divided into the first partition structure 131 and the second partition structure 132 .

[0039] Except for the above differences, the other structures of the first connector 10 ′ are the same as those of the first connector 10 , and thus will not be described again here.

[0040] like Figure 8 As shown, it is Figure 7The first connector 10 is deformed. Figure 8 In the embodiment, the first connector 10ˋˋ and Figure 7 The difference of the first connector 10 is that the second partition structure 132 in the partition structure 13 is a continuous structure that is not interrupted by the first partition structure 131, and correspondingly, the first partition structure 131 is an intermittent structure that is interrupted by the second partition structure 132. Figure 7 In the first connector 10 shown, the first partition structure 131 of the partition structure 13 is a continuous structure that is not interrupted by the second partition structure 132 , and correspondingly, the second partition structure 132 is a discontinuous structure that is interrupted by the first partition structure 131 .

[0041] Except for the above-mentioned differences, other structures of the first connector 10 '' are the same as those of the first connector 10 '', and thus will not be described again here.

[0042] Compared with the prior art, the design of "a partition structure 13 (13ˋ, 13ˋˋ) is provided in the plug-in cavity 11a, and the partition structure 13 (13ˋ, 13ˋˋ) divides the plug-in cavity 11a into a corresponding number of partition areas 111, and each first terminal 12 is located in a corresponding partition area 111" allows a small amount of water that penetrates to be confined to the partition area 111, thereby effectively preventing a short circuit and electric contact between the first terminals 12 caused by the small amount of water that penetrates.

[0043] It is worth noting that, since the second terminals 22 are matched with the first terminals 12, the arrangement of the second terminals 22 is consistent with the arrangement of the first terminals 12. Figure 5 In the figure, reference numeral 11d denotes a through hole for the first terminal 12 to be inserted and installed. Furthermore, since the second connector 20 mates with the first connector 10 (10ˋ, 10ˋˋ), when the structure of the first connector 10 (10ˋ, 10ˋˋ) changes, the structure of the second connector 20 for mating with the first connector 10 (10ˋ, 10ˋˋ) also changes accordingly.

[0044] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
