Modes for carrying out the invention
[0021] Fig. 1 is a structural view of a male connector according to a first embodiment of the present invention. As shown in fig. 1, the male connector of the present embodiment includes a first terminal set 110, a first rubber core 120, and at least one first barrier 130.
[0022] Specifically, the first terminal group 110 includes a plurality of first terminals 111 (only 3 are shown in the figure, but the present invention is not limited thereto).
[0023] The first rubber core 120 includes at least one insertion hole, and each insertion hole is inserted with one first terminal 111, that is, each first terminal 111 of the first terminal group 110 has one insertion hole corresponding to the first rubber core 120. The first terminal set 110 is divided into three parts, and the first part of the first terminal 110 is located outside the tail of the male connector and the first rubber core 120 and connected to the signal line. The second portion of the first terminal 110 is located inside the first core plastic 120. The third portion of the first terminal 110 is located outside the head of the male connector and the first rubber core 120, and is connected to the second terminal 211 of the corresponding female connector.
[0024] The first blocking wall 130 is made of an insulating material, so that water vapor is prevented from conducting electricity through the first blocking wall 130. The first blocking wall 130 is connected to the side of the first rubber core 120 where the plug holes are located, that is, the first blocking wall 130 is located at the tail of the male connector (as shown in fig. 1), or located at the head of the male connector (not shown in fig. 1), or located at the tail of the male connector and the head of the male connector (not shown in fig. 1) in a same inch.
[0025] The first blocking wall 130 is located between two adjacent first terminals 111 of the first terminal group 110, the length of the first blocking wall 130 is not less than the length of the first terminal 111 adjacent to the first blocking wall 130, the upper surface of the first blocking wall 130 is not lower than the upper surface of the first terminal 111 adjacent to the first blocking wall 130, and the lower surface of the first blocking wall 130 is not higher than the lower surface of the first terminal 111 adjacent to the first blocking wall 130.
[0026] The length of the first blocking wall 130 and the length of the first terminal 111 are both distances extending outward relative to the first rubber core 120, and the same is true in other embodiments of the present invention, and a description thereof is not repeated.
[0027]Specifically, for the second part of the first terminal set 110, i.e. the first terminal set 110 located inside the first rubber core 120, each first terminal 111 is separated and deployed by the insertion hole of the first rubber core 120, so that moisture, dust and the like entering from the head of the male connector and a certain first terminal are separated and deployedU 1At the first rubber core120After the internal contact, the first terminals 111 cannot be contacted with other first terminals 111 through the first rubber core 120, so that the first terminals 111 are mutually conductive; moreover, the first plastic core 120 is insulating, so that moisture, dust, etc. cannot pass through the first plastic core 120 to make the first terminals 111 electrically conductive. It is not possible for moisture, dust, etc. to conduct electricity on the male connector at the second portion of the first terminal set 110.
[0028] As shown in fig. 1, for the first terminal set 110, which is located at the tail of the male connector and outside the first rubber core 120, at least one first blocking wall 130 is disposed at the tail of the male connector. A first blocking wall 130 is disposed between every two adjacent first terminals 111, and the first blocking wall 130 is connected to the side of the first rubber core 120 where the insertion holes are disposed. The length of the first blocking wall 130 is not less than the length of the first terminal 111 adjacent to the first blocking wall 130, the opposite sides of the adjacent first terminals 111 cannot be opposite to each other across the first blocking wall 130 in the length direction. The upper surface of the first blocking wall 130 is not lower than the upper surface of the first terminal 111 adjacent to the first blocking wall 130, and the lower surface of the first blocking wall 130 is not higher than the lower surface of the first terminal 111 adjacent to the first blocking wall 130, so that the opposite sides of the adjacent first terminals 111 cannot be opposed to each other across the first blocking wall 130 in the height direction. Thus, the first blocking walls 130 block the lengths and heights of the opposite sides of the adjacent first terminals 111 from directly facing each other, so that the adjacent first terminals 111 cannot directly face each other. Therefore, after the moisture and dust contact with a certain first terminal 111, they cannot pass through the first blocking wall 130 to contact with the adjacent first terminal 111, so that the first terminals 111 are electrically conductive; in addition, the first blocking wall 130 is insulated, so that moisture and dust cannot pass through the first blocking wall 130 to make the first terminals 111 electrically conductive, and the first blocking wall 130 is additionally arranged between the first terminals 111 at the tail part of the male connector to prevent moisture from gathering easily, thereby preventing short circuit burn-in.
[0029] For the third portion of the first terminal set 110, i.e., the first terminal set 110 outside the head of the male connector and the first rubber core 120, at least one first blocking wall 130 may be disposed on the head of the male connector. A first blocking wall 130 is disposed between every two adjacent first terminals 111, and the first blocking wall 130 is connected to the side of the first rubber core 120 where the insertion holes are disposed. The length of the first blocking wall 130 is not less than the length of the first terminal 111 adjacent to the first blocking wall 130, the opposite sides of the adjacent first terminals 111 cannot be opposite to each other across the first blocking wall 130 in the length direction. The upper surface of the first blocking wall 130 is not lower than the upper surface of the first terminal 111 adjacent to the first blocking wall 130, and the lower surface of the first blocking wall 130 is not higher than the lower surface of the first terminal 111 adjacent to the first blocking wall 130, so that the opposite side surfaces of the adjacent first terminals 111 cannot be opposite to each other across the first blocking wall 130 in the height direction. Thus, the first blocking walls 130 block the lengths and heights of the opposite sides of the adjacent first terminals 111 from directly facing each other, so that the adjacent first terminals 111 cannot directly face each other. Therefore, after the moisture and dust contact with one first terminal 111, the moisture and dust cannot pass through the first blocking wall 130 to contact with the adjacent first terminal 111, so that the first terminals 111 are electrically conductive; and the first blocking walls 130 are insulated, moisture and dust cannot pass through the first blocking walls 130 to make the first terminals 111 electrically conductive with each other. Therefore, in an embodiment of the present invention, the first blocking wall 130 for insulation can be added between the first terminals 111 of the header of the male connector to prevent moisture from accumulating easily, thereby preventing short circuit burn-in.
[0030] In the embodiment of fig. 1, the first blocking wall 130 is disposed at the tail of the male connector, but the present invention is not limited thereto, for example, in another embodiment of the present invention, the first blocking wall 130 may be disposed at only the head of the male connector, or in another embodiment of the present invention, the first blocking wall 130 may be disposed at both the tail of the male connector and the head of the male connector.
[0031] In an embodiment of the invention, all the first blocking walls 130 have the same length and the same height, the length of the first blocking walls 130 is not less than the length of all the first terminals 111, the upper surface of the first blocking walls 130 is not lower than the upper surface of all the first terminals 111, and the lower surface of the first blocking walls 130 is not higher than the lower surface of all the first terminals 111. Thus, the first blocking wall 130 is easy to design and machine.
[0032] In an embodiment of the present invention, the first blocking wall 130 is located between two adjacent first terminals 111, the first blocking wall 130 is a right-angled triangular prism, and a plane where a bottom surface of the right-angled triangular prism is located is on a plane where the first blocking wall 130 is connected to the first rubber core 120. Thus, the first blocking wall 130 has a simple structure and is convenient to process. However, the shape of the first blocking wall 130 is not limited in this way, and the shape of the first blocking wall 130 may be changed in distance from the surface of the first rubber core 120 connected to the first blocking wall 130, so that the male connector and the corresponding female connector are connected in an inch, and the shape of the first blocking wall 130 may be matched with the shape of the female connector. For example, the first blocking wall 130 may be an isosceles triangular prism or other triangular prism, or may be a trapezoidal prism, a concave shape or a convex shape, etc.
[0033] In one embodiment of the present invention, the first blocking wall 130 is an elongated shape. Thus, the first blocking wall 130 has a simple structure and is convenient to process.
[0034] In one embodiment of the present invention, the first rubber core 120 and the first wall 130 are integrally formed by injection molding. The first blocking wall 130 is made of plastic, and the first rubber core 120 and the first blocking wall 130 are formed by injection molding for processing convenience. In addition, for the convenience of processing, the first terminal 111, the first rubber core 120 and the first partition wall 130 may be integrally injection molded.
[0035] In the male connector according to the first embodiment of the present invention, the first insulating barrier 130 is disposed between two adjacent first terminals 111 of the first terminal group 110, so that moisture is not easily accumulated between the two adjacent first terminals 111, thereby preventing short circuit and burn-in.
[0036] Fig. 2 is an exploded structural view of a male connector according to a second embodiment of the present invention. The male connector shown in fig. 2 is substantially the same in structure as the male connector shown in fig. 1, except that: the cover is equipped with first terminal protective sheath 140 on the first gluey core 120, and the outer cladding of first terminal protective sheath 140 has iron cover 150, and the lower surface of iron cover 150 is equipped with first hole for combustion 151, second hole for combustion 152. The first hole 151 and the second hole 152 are used for being matched with the corresponding elastic sheet lock catch of the female connector to achieve the clamping effect.
[0037] In an embodiment of the present invention, at least one outwardly bent leg 153 is disposed on each of both sides of the rear end of the iron cover 150.
[0038] As shown in fig. 2, the male connector of the present embodiment includes a first terminal set 110 and a first rubber core 12
0 and at least one first wall 130.
[0039] Specifically, the first terminal group 110 includes a plurality of first terminals 111.
[0040] The first rubber core 120 includes at least one insertion hole, and each insertion hole is inserted with one first terminal 111, that is, each first terminal 111 of the first terminal group 110 has one insertion hole corresponding to the first rubber core 120. The first terminal set 110 is divided into three parts, and the first part of the first terminal 110 is located outside the tail of the male connector and the first rubber core 120 and connected to the signal line. The second portion of the first terminal 110 is located inside the first core plastic 120. The third portion of the first terminal 110 is located outside the head of the male connector and the first rubber core 120, and is connected to the second terminal 211 of the corresponding female connector.
[0041] The first blocking wall 130 is made of an insulating material, so that water vapor is prevented from conducting electricity through the first blocking wall 130. The first blocking wall 130 is connected to the side of the first rubber core 120 where the plug holes are located, that is, the first blocking wall 130 is located at the tail of the male connector (as shown in fig. 2), or at the head of the male connector (not shown in fig. 2), or at the tail of the male connector and the head of the male connector (not shown in fig. 2).
[0042] The first blocking wall 130 is located between two adjacent first terminals 111 of the first terminal group 110, the length of the first blocking wall 130 is not less than the length of the first terminal 111 adjacent to the first blocking wall 130, the upper surface of the first blocking wall 130 is not lower than the upper surface of the first terminal 111 adjacent to the first blocking wall 130, and the lower surface of the first blocking wall 130 is not higher than the lower surface of the first terminal 111 adjacent to the first blocking wall 130.
[0043]Specifically, for the second part of the first terminal set 110, i.e. the first terminal set 110 located inside the first rubber core 120, each first terminal 111 is separated and deployed by the insertion hole of the first rubber core 120, so that moisture, dust and the like entering from the head of the male connector and a certain first terminal are separated and deployedU 1At the first rubber core120After the internal contact, the first terminals 111 cannot be contacted with other first terminals 111 through the first rubber core 120, so that the first terminals 111 are mutually conductive; moreover, the first plastic core 120 is insulating, so that moisture, dust, etc. cannot pass through the first plastic core 120 to make the first terminals 111 electrically conductive. It is not possible for moisture, dust, etc. to conduct electricity on the male connector at the second portion of the first terminal set 110.
[0044] As shown in fig. 1, for the first terminal set 110, which is located at the tail of the male connector and outside the first rubber core 120, at least one first blocking wall 130 is disposed at the tail of the male connector. A first blocking wall 130 is disposed between every two adjacent first terminals 111, and the first blocking wall 130 is connected to the side of the first rubber core 120 where the insertion holes are disposed. The length of the first blocking wall 130 is not less than the length of the first terminal 111 adjacent to the first blocking wall 130, the opposite sides of the adjacent first terminals 111 cannot be opposite to each other across the first blocking wall 130 in the length direction. The upper surface of the first blocking wall 130 is not lower than the upper surface of the first terminal 111 adjacent to the first blocking wall 130, and the lower surface of the first blocking wall 130 is not higher than the lower surface of the first terminal 111 adjacent to the first blocking wall 130, so that the opposite sides of the adjacent first terminals 111 cannot be opposed to each other across the first blocking wall 130 in the height direction. Thus, the first blocking walls 130 block the lengths and heights of the opposite sides of the adjacent first terminals 111 from directly facing each other, so that the adjacent first terminals 111 cannot directly face each other. Therefore, after the moisture and dust contact with a certain first terminal 111, they cannot pass through the first blocking wall 130 to contact with the adjacent first terminal 111, so that the first terminals 111 are electrically conductive; moreover, the first blocking wall 130 is insulating, and moisture and dust cannot pass through the first blocking wall 130 to make the first terminals 111 conductive, so that the embodiment can add the insulating first blocking wall 130 between the first terminals 111 at the tail of the male connector to make moisture not easily gather, thereby preventing short circuit and burn out.
[0045] For the third portion of the first terminal set 110, i.e. the first terminal set 110 located outside the head of the male connector and the first rubber core 120, at least one first blocking wall 130 may be disposed at the head of the male connector. A first blocking wall 130 is disposed between every two adjacent first terminals 111, and the first blocking wall 130 is connected to the side of the first rubber core 120 where the insertion holes are disposed. The length of the first blocking wall 130 is not less than the length of the first terminal 111 adjacent to the first blocking wall 130, the opposite sides of the adjacent first terminals 111 cannot be opposite to each other across the first blocking wall 130 in the length direction. The upper surface of the first blocking wall 130 is not lower than the upper surface of the first terminal 111 adjacent to the first blocking wall 130, and the lower surface of the first blocking wall 130 is not higher than the lower surface of the first terminal 111 adjacent to the first blocking wall 130, so that the opposite side surfaces of the adjacent first terminals 111 cannot be opposite to each other across the first blocking wall 130 in the height direction. Thus, the first blocking walls 130 block the lengths and heights of the opposite sides of the adjacent first terminals 111 from directly facing each other, so that the adjacent first terminals 111 cannot directly face each other. Therefore, after the moisture and dust contact with one first terminal 111, the moisture and dust cannot pass through the first blocking wall 130 to contact with the adjacent first terminal 111, so that the first terminals 111 are electrically conductive; and the first blocking walls 130 are insulated, moisture and dust cannot pass through the first blocking walls 130 to make the first terminals 111 electrically conductive with each other. Therefore, in an embodiment of the present invention, the first blocking wall 130 for insulation can be added between the first terminals 111 of the header of the male connector to prevent moisture from accumulating easily, thereby preventing short circuit burn-in.
[0046] In the embodiment of fig. 1, the first blocking wall 130 is disposed at the tail of the male connector, but the present invention is not limited thereto, for example, in another embodiment of the present invention, the first blocking wall 130 may be disposed at only the head of the male connector, or in another embodiment of the present invention, the first blocking wall 130 may be disposed at both the tail of the male connector and the head of the male connector.

The second blocking wall 230 is connected to the side of the second rubber core where the plug hole is located, that is, the second blocking wall 230 is located at the tail of the female connector, or located at the head of the female connector, or located at both the tail of the female connector and the head of the female connector.
[0053] The second blocking wall 230 is located between two adjacent second terminals 211 of the second terminal set, the length of the second blocking wall 230 is not less than the length of the second terminal 211 adjacent to the second blocking wall 230, the upper surface of the second blocking wall 230 is not lower than the upper surface of the second terminal 211 adjacent to the second blocking wall 230, and the lower surface of the second blocking wall 230 is not higher than the lower surface of the second terminal 211 adjacent to the second blocking wall 230.
[0054] The length of the second blocking wall 230 and the length of the second terminal 211 are both distances extending outward relative to the second rubber core, and the same is true in other embodiments of the present invention, and a description thereof is not repeated.
[0055] Specifically, for the second portion of the second terminal group, the second terminals 211 are separately secured by the insertion holes of the second plastic core, so that moisture, dust, etc. entering from the head of the female connector are not able to pass through the second plastic core to contact with other second terminals 211 after contacting with a certain second terminal 211 inside the second plastic core, so that the second terminals 211 are electrically conductive to each other; and the second gel core is insulating, moisture, dust, etc. cannot make the second terminals 211 electrically conductive with each other through the second gel core. It is impossible to conduct electricity on the female connector at the second portion of the second terminal set due to moisture, dust, etc.
[0056] For the first portion of the second terminal set, i.e., the second terminal set located outside the tail portion of the female connector and the second rubber core 220, at least one second blocking wall 230 may be disposed at the tail portion of the female connector. A second barrier 230 is disposed between every two adjacent second terminals 211, and the second barrier 230 is connected to the side of the second plastic core where the insertion holes are disposed. The length of the second blocking wall 230 is not less than the length of the second terminal 211 adjacent to the second blocking wall 230, and the opposite sides of the adjacent second terminal 211 cannot be opposite to each other across the second blocking wall 230 in the length direction. The upper surface of the second blocking wall 230 is not lower than the upper surface of the second terminal 211 adjacent to the second blocking wall 230, and the lower surface of the second blocking wall 230 is not higher than the lower surface of the second terminal 211 adjacent to the second blocking wall 230, so that the opposite side surfaces of the adjacent second terminals 211 cannot be opposite to each other across the second blocking wall 230 in the height direction. Thus, the second blocking walls 230 block the lengths and heights of the opposite sides of the adjacent second terminals 211 from directly facing each other so that the adjacent second terminals 211 cannot directly face each other. Therefore, moisture, dust, etc. contacting a certain second terminal 211 cannot pass through the second blocking wall 230 to contact an adjacent second terminal 211, so that the second terminals 211 are electrically conducted; and the second blocking walls 230 are insulated, moisture, dust, etc. cannot pass through the second blocking walls 230 to make the second terminals 211 electrically conductive with each other. Therefore, in one embodiment of the present invention, the second barrier 230 is added between the second terminals 211 at the tail of the female connector to prevent moisture from accumulating, thereby preventing short circuit and burn-in.
For the third portion of the second terminal set, i.e., the second terminal set located outside the header of the female connector and the second rubber core 220, at least one second blocking wall 230 may be disposed at the header of the female connector. A second barrier 230 is disposed between every two adjacent second terminals 211, and the second barrier 230 is connected to the side of the second plastic core where the insertion holes are disposed. The length of the second blocking wall 230 is not less than the length of the second terminal 211 adjacent to the second blocking wall 230, and the opposite sides of the adjacent second terminal 211 cannot be opposite to each other across the second blocking wall 230 in the length direction. The upper surface of the second blocking wall 230 is not lower than the upper surface of the second terminal 211 adjacent to the second blocking wall 230, and the lower surface of the second blocking wall 230 is not higher than the lower surface of the second terminal 211 adjacent to the second blocking wall 230, so that the opposite side surfaces of the adjacent second terminals 211 cannot be opposite to each other across the second blocking wall 230 in the height direction. Thus, the second blocking walls 230 block the lengths and heights of the opposite sides of the adjacent second terminals 211 from directly facing each other so that the adjacent second terminals 211 cannot directly face each other. Therefore, moisture, dust, etc. contacting a certain second terminal 211 cannot pass through the second blocking wall 230 to contact an adjacent second terminal 211, so that the second terminals 211 are electrically conducted; and the second blocking walls 230 are insulated, moisture, dust, etc. cannot pass through the second blocking walls 230 to make the second terminals 211 electrically conductive with each other. Therefore, in an embodiment of the present invention, the second barrier 230 is additionally disposed between the second terminals 211 of the header of the female connector to prevent moisture from accumulating, thereby preventing short-circuit burn-in. [0058] In one embodiment of the present invention, the second blocking wall 230 is disposed at the head of the female connector, but the present invention is not limited thereto, for example, in another embodiment of the present invention, the second blocking wall 230 is disposed only at the tail of the female connector, or in another embodiment of the present invention, the second blocking wall 230 is disposed at both the tail of the female connector and the head of the female connector.
