Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the accompanying drawings are illustrative and are only for the purpose of explaining the present application and are not to be construed as limiting the present application.

The Type-C is the latest USB interface appearance standard, and the plug end can be inserted into the corresponding socket end from the positive direction and the negative direction, so that the worldwide problem of 'USB cannot be inserted forever' is formally solved. The Type-C socket end is provided with an upper row of conductive terminals and a lower row of conductive terminals, each row of conductive terminals comprises a signal terminal, a grounding terminal and a power supply terminal, the power supply terminals are used for electrifying, and the overcurrent capacity of the power supply terminals is positively correlated with the cross-sectional area of the power supply terminals. However, the lateral width of the power supply terminal cannot be widened because it needs to be kept a sufficient distance from the adjacent terminal to match the plug, and the maximum overcurrent capacity can only reach about 8A.

In view of the above, the present inventors have studied and provided a USB connector, which fully utilizes the space in the thickness direction of the insulating body, and partially contacts the first power terminal and the second power terminal in the plugging direction of the insulating body to form a short circuit, so as to increase the overcurrent area of the first power terminal and the second power terminal, thereby greatly enhancing the overcurrent capability of the first power terminal and the second power terminal without increasing the lateral width of the first power terminal and the second power terminal. Simulation results show that the overcurrent capacity of the USB connector is increased to 11.5A, which is enhanced by 50% compared with the related art.

The USB connector that this application embodiment provided can be Type-C socket, and first power supply terminal and second power supply terminal are used as the VBus terminal of Type-C socket. Of course, the USB connector may be other connecting sockets having power terminals, such as Type-a or Type-B, and the embodiment of the present application will be described by taking a Type-C socket with a USB connector of 24Pin as an example. In other embodiments, the USB connector may also be a 6Pin, 12Pin, or 16Pin Type-C receptacle.

In some embodiments, the first and

second insertion parts

1211 and 1221 are spaced apart from each other in the insertion direction of the insulation body 110 to form a first glue receiving space 141, the first and second

middle parts

1212 and 1222 are at least partially in contact with each other in the insertion direction of the insulation body 110 to short the first and

second power terminals

121 and 122, and the glue receiving space 140 includes the first glue receiving space 141.

The first glue containing space 141 can be used for filling structural glue, and the insulating body 110 is connected with the first power terminal 121 and the second power terminal 122 in an adhering manner through the structural glue; or, when the insulation body 100 is injection molded, the insulation body 110 may be directly filled in the first glue containing space 141 during the injection molding process to form a glue pulling structure, and the insulation body 110 may also be firmly attached to the first power terminal 121 and the second power terminal 122, so as to improve the connection strength between the insulation body 110 and the terminal assembly 120.

In this embodiment, the first plugging portion 1211 and the second plugging portion 1221 are mainly used for being in contact with a plug of a data line, and whether the first plugging portion 1211 and the second plugging portion 1221 are in contact in the thickness direction of the insulating body 110 does not greatly affect the overcurrent capacity, so that in this embodiment, the first plugging portion 1211 and the second plugging portion 1221 are spaced from each other in the thickness direction of the insulating body 110 to form the first glue containing space 141, so that the connection strength of the terminal assembly 120 of the insulating body 110 is improved on the premise of not affecting the overcurrent capacity.

In other embodiments, the first plug 1211 and the second plug 1221 may partially contact each other and partially space each other in the thickness direction of the insulating body 110; alternatively, the first and

second plug portions

1211 and 1221 completely contact each other in the thickness direction of the insulating body 110.

In some embodiments, the sides of first plug portion 1211 and first middle portion 1212 facing away from second power terminal 122 are flush with each other, and the thickness of first plug portion 1211 is smaller than that of first middle portion 1212; the second plug section 1221 and the side of the second intermediate section 1222 facing away from the first power terminal 121 are flush with each other, and the thickness of the second plug section 1221 is smaller than that of the second intermediate section 1222. Thus, the first intermediate portion 1212 and the second intermediate portion 1222 can be brought into contact with each other in the thickness direction, while the first plug portion 1211 and the second plug portion 1221 are spaced apart from each other in the thickness direction, and the first power terminal 121 and the second power terminal 122 can be easily press-molded. As an embodiment, the first power terminal 121 and the second power terminal 122 may be separately press-formed by a copper material.

In some embodiments, a second glue containing space 142 is disposed between the first middle portion 1212 and the second middle portion 1222, that is, the first middle portion 1212 and the second middle portion 1222 are at least partially spaced apart from each other in the plugging direction of the insulation body 110 to form a second glue containing space 142, and the glue containing space 140 includes the second glue containing space 142.

The second glue containing space 142 can be used for filling structural glue, and the insulation body 110 is connected with the first power terminal 121 and the second power terminal 122 in an adhesion manner through the structural glue; or, when the insulation body 100 is injection molded, the insulation body 110 may be directly filled in the second glue containing space 142 during the injection molding process to form a glue pulling structure, so that the insulation body 110 may be stably attached to the first power terminal 121 and the second power terminal 122, and the connection strength between the insulation body 110 and the terminal assembly 120 is improved.

In this embodiment, the second glue containing space 142 may be located at one end of the first middle portion 1212 and the second middle portion 1222 close to the first welding portion 1213 and the second welding portion 1223, that is, the distance between the second glue containing space 142 and the first insertion portion 1211 is greater than the distance between the second glue containing space 142 and the first welding portion 1213, so that the first glue containing space 141 and the second glue containing space 142 are substantially distributed at both ends of the first middle portion 1212 and the second middle portion 1222 in the length direction, and the first middle portion 1212 and the second middle portion 1222 may be more stably maintained in a contact state by a glue pulling structure formed by the first glue containing space 141 and the second glue containing space 142.

The second glue containing space 142 penetrates through the first middle portion 1212 and the second middle portion 1222 along the width direction of the insulation body 110, and the first middle portion 1212 and the second middle portion 1222 contact each other at both ends of the second glue containing space 142 along the plugging direction, wherein the width direction of the insulation body 110 is perpendicular to the plugging direction and the thickness direction of the insulation body 110. Therefore, the second glue containing space 142 with a through hole shape can be formed, so that the insulation body 110 can conveniently flow into the second glue containing space 142 in the injection molding process.

In other embodiments, the second glue containing space 142 may not extend through the first middle portion 1212 and the second middle portion 1222, for example, the width of the second glue containing space 142 may be smaller than the width of the first middle portion 1212 and the second middle portion 1222, and the second glue containing space 142 is a groove-like structure disposed between the first middle portion 1212 and the second middle portion 1222.

In some embodiments, the first power terminal 121 and the second power terminal 122 are provided with the glue containing space 140 between the regions with gradually widened widths, so that the first power terminal 121 and the second power terminal 122 can balance and offset the narrowing of the overcurrent area caused by the thickness occupied by the glue containing space 140 through the widened regions when overcurrent occurs, and further avoid the problem of causing current "blocking".

In some embodiments, the first middle portion 1212 and the second middle portion 1222 define a second glue receiving space 142 between regions of increasing width. Specifically, the first middle portion 1212 may include a first sub-middle portion and a second sub-middle portion connected in sequence between the first plug portion 1211 and the first welding portion 1213, the second sub-middle portion having a width greater than that of the first sub-middle portion, and the second glue receiving space 142 being located at a connection of the first sub-middle portion and the second sub-middle portion; similarly, the second middle portion 1222 includes a third sub-middle portion and a fourth sub-middle portion connected between the second plug portion 1221 and the second welding portion 1223 in sequence, the width of the fourth sub-middle portion is greater than that of the third sub-middle portion, and the second glue receiving space 142 is located at the connection position of the third sub-middle portion and the fourth sub-middle portion. Therefore, the first middle part 1212 and the second middle part 1222 can balance and offset the narrowing of the flowing area caused by the thickness occupied by the second glue containing space 142 through the widened area when the current flows, and further avoid the problem of current blocking.

In some embodiments, first middle portion 1212 is provided with a first glue-pulling groove 1216, the first glue-pulling groove 1216 being located partially in the first sub-middle portion and partially in the second sub-middle portion; the second middle portion 1222 is provided with a second glue pulling groove 1226, the second glue pulling groove 1226 is partially located in the third sub-middle portion, and partially located in the fourth sub-middle portion, and the first glue pulling groove 1216 and the second glue pulling groove 1226 are oppositely arranged and mutually communicated to form a second glue containing space 142. The first glue pulling groove 1216 and the second glue pulling groove 1226 can be manufactured conveniently by punch forming.

In this embodiment, the lengths of the first glue pulling groove 1216 and the second glue pulling groove 1226 in the inserting direction may be equal or unequal, and when the lengths of the first glue pulling groove 1216 and the second glue pulling groove 1226 in the inserting direction are unequal, a step structure may be formed in the second glue containing space 142, so as to further improve the glue pulling effect.

In this embodiment, the first glue groove 1216 may extend through the first middle portion 1212 in the width direction of the first middle portion 1212, and the second glue groove 1226 may extend through the second middle portion 1222 in the width direction of the second middle portion 1222 to form the through-hole-shaped second glue receiving space 142.

Also, the third power terminal 123 and the fourth power terminal 124 may be partially contacted in the plugging direction of the insulation body 110 to be shorted, thereby enhancing the overcurrent capability of the third power terminal 123 and the fourth power terminal 124. For the specific structure of the third power terminal 123, the first power terminal 121 can be referred to, and for the specific structure of the fourth power terminal 124, the second power terminal 122 can be referred to, which is not described herein again.
