Detailed Description
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.
Specifically, the first terminal set 110 includes a plurality of first terminals 111 (only 3 are shown in the figure, but the present invention is not limited thereto).
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 a signal line. The second portion of the first terminal 110 is located inside the first rubber core 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.
The first barrier 130 is made of an insulating material to prevent water vapor from conducting through the first barrier 130. The first blocking wall 130 is connected to the side of the first rubber core 120 where the jack is located, that is, the first blocking wall 130 is located at the tail of the male connector (as shown in fig. 1), or at the head of the male connector (not shown in fig. 1), or at both the tail of the male connector and the head of the male connector (not shown in fig. 1).
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.
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.
Specifically, for the second part of the first terminal group 110, i.e. the first terminal group 110 located inside the first rubber core 120, each first terminal 111 is separated by the insertion hole of the first rubber core 120, so that moisture, dust, etc. entering from the head of the male connector can not pass through the first rubber core 120 to contact with other first terminals 111 after contacting with a certain first terminal 111 inside the first rubber core 120, and the first terminals 111 are electrically conductive to each other; and the first plastic core 120 is insulating, moisture, dust, etc. cannot make the first terminals 111 electrically conductive with each other through the first plastic core 120. 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.
For the first terminal set 110, which is located at the tail of the male connector and outside the first rubber core 120, as shown in fig. 1, 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, and 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; 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 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 and burn-in.
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, and 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 barrier 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 and burn-in.
In the embodiment of fig. 1, the first blocking wall 130 is disposed at the tail portion 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 only at the head portion of the male connector, or in another embodiment of the present invention, the first blocking wall 130 is disposed at both the tail portion and the head portion of the male connector.
In an embodiment of the invention, all the first blocking walls 130 have the same length and the same height, and 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 barrier 130 is easily designed and manufactured.
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 shape of the first blocking wall 130 can be matched with the shape of the corresponding female connector when the male connector is connected to 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.
In one embodiment of the present invention, the first barrier 130 is an elongated structure. Thus, the first blocking wall 130 has a simple structure and is convenient to process.
In an embodiment of the present invention, the first rubber core 120 and the first partition 130 are integrally injection molded. The first blocking wall 130 is made of plastic, and the first rubber core 120 and the first blocking wall 130 are integrally 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 130 may be integrally injection-molded.
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.
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 first rubber core 120 is sleeved with a first terminal protection sleeve 140, the first terminal protection sleeve 140 is wrapped with an iron cover 150, and the lower surface of the iron cover 150 is provided with a first opening 151 and a second opening 152. The first opening 151 and the second opening 152 are used for being matched with the corresponding spring plate lock of the female connector to play a clamping role.
In an embodiment of the present invention, at least one solder leg 153 bent outward is disposed on each of two sides of the rear end of the iron cover 150.
As shown in fig. 2, 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.
Specifically, the first terminal group 110 includes a plurality of first terminals 111.
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 a signal line. The second portion of the first terminal 110 is located inside the first rubber core 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.
The first barrier 130 is made of an insulating material to prevent water vapor from conducting through the first barrier 130. The first blocking wall 130 is connected to the side of the first rubber core 120 where the jack is 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 both the tail of the male connector and the head of the male connector (not shown in fig. 2).
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.
Specifically, for the second part of the first terminal group 110, i.e. the first terminal group 110 located inside the first rubber core 120, each first terminal 111 is separated by the insertion hole of the first rubber core 120, so that moisture, dust, etc. entering from the head of the male connector can not pass through the first rubber core 120 to contact with other first terminals 111 after contacting with a certain first terminal 111 inside the first rubber core 120, and the first terminals 111 are electrically conductive to each other; and the first plastic core 120 is insulating, moisture, dust, etc. cannot make the first terminals 111 electrically conductive with each other through the first plastic core 120. 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.
For the first terminal set 110, which is located at the tail of the male connector and outside the first rubber core 120, as shown in fig. 1, 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, and 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; 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 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 and burn-in.
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, and 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 barrier 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 and burn-in.
In the embodiment of fig. 1, the first blocking wall 130 is disposed at the tail portion 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 only at the head portion of the male connector, or in another embodiment of the present invention, the first blocking wall 130 is disposed at both the tail portion and the head portion of the male connector.

The first opening 151 and the second opening 152 are used to cooperate with the openings of the corresponding female connectors to function as a detent.
The invention also provides a USB connector comprising the male connector. For the structure and principle of the male connector, please refer to the above description, which is not repeated herein. In one embodiment, the USB connector may further include a female connector connected to the male connector.
Fig. 3 is a front schematic view of a connection portion of a male connector and a female connector of a USB connector according to a third embodiment of the present invention. The USB connector includes a male connector. The USB connector may also include a female connector. The USB connector of the present embodiment includes a male connector and a female connector. The structure of the male connector can refer to the structure of the male connector in the first embodiment or the second embodiment. The female connector includes a second terminal set, a second rubber core, and at least one second dam 230. The second terminal set includes a plurality of second terminals 211.
Specifically, the second terminal group includes a plurality of second terminals 211, and in an embodiment of the present invention, the number of the second terminals 211 is the same as the number of the first terminals 110, for electrically connecting with the first terminals 110.
The second plastic core comprises at least one jack, each jack is inserted with one second terminal 211, namely, each second terminal 211 of the second terminal group has a jack corresponding to the jack on the second plastic core. The second terminal group is divided into three parts, and the first part of the second terminal group is positioned at the tail part of the female connector and outside the second rubber core and is connected with the signal wire. The second part of the second terminal group is positioned in the second rubber core. The third part of the second terminal group is located outside the head of the female connector and the second rubber core and is connected with the first terminal 111 of the corresponding male connector.
The second barrier 230 is made of an insulating material to prevent water vapor from conducting through the second barrier 230. 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 at the head of the female connector, or at both the tail of the female connector and the head of the female connector.
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.
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.
Specifically, for the second part of the second terminal group, each second terminal 211 is separated by the jack of the second rubber core, so that after water vapor, dust and the like entering from the head of the female connector contact with one second terminal 211 in the second rubber core, the water vapor, dust and the like cannot pass through the second rubber core to contact with other second terminals 211, so that the second terminals 211 are mutually conductive; 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.
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 blocking wall 230 is arranged between every two adjacent second terminals 211, and the second blocking wall 230 is connected with one face of the second rubber core, which is provided with the insertion holes. 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 opposite sides of the adjacent second terminals 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 barrier 230 blocks 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, after moisture, dust, and the like contact one second terminal 211, the moisture, dust, and the like cannot pass through the second blocking wall 230 to contact the adjacent second terminal 211, so that the second terminals 211 are electrically conductive; 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.
