Description

Technical Field

[0001] The present invention relates to the technology of connector field, and in particular to a side-standing fast-charging connector. Background Art

[0002] With the continuous development of electronic products, electronic products are becoming more and more popular in life, and consumers have an increasing demand for miniaturized electronic products. USB electrical connectors have gradually become the development trend of modern data transmission with their advantages such as fast, plug-and-play, and easy installation. At present, USB electrical connectors have become the mainstream interface for computers, mobile phone chargers, and car chargers. With the further improvement of USB interface technology, the application of USB interface technology will be further expanded.

[0003] At present, there are two types of electrical connectors: flat-laying electrical connectors and side-insertion electrical connectors. The tongue of the flat-laying electrical connector is roughly parallel to the circuit board it is connected to, so it will occupy a wider circuit board area. The tongue of the side-insertion electrical connector is roughly perpendicular to the circuit board it is connected to, so it can reduce the use area of ​​the circuit board and contribute to the development of miniaturization of electronic products.

[0004] However, the existing side-insertion connectors have the following disadvantages:

[0005] 1. If Figure 1 As shown, when the fast charging terminal is placed in the injection mold to inject the insulating body, the fixed end holes 101' are arranged in a row with longitudinal spacing. Such an arrangement will hinder the flow of plastic and cause diversion, making it difficult for the product to fill the mold, which will lead to an incomplete insulating body.

[0006] 2. The plug-in ends of multiple conductive terminals are too close to each other, resulting in signal crosstalk between the terminals.

[0007] 3. The plug-in ends of multiple conductive terminals are basically all exposed outside the connector. If impurities come into contact with this part, it is easy to cause a short circuit in the connector, thus affecting the service life of the product. At the same time, electromagnetic waves are exposed, resulting in poor EMI effect of the product.

[0008] 4. The front ends of multiple conductive terminals are not pre-pressed, resulting in inconsistent terminal heights. When male and female terminals are plugged in, the terminals are prone to pin breakage, making the connector unstable.

[0009] 5. The existing side-standing connector has poor waterproof and anti-fouling performance, and stains can easily enter the inside of the connector, causing the connector to short-circuit and affect its use. Summary of the invention

[0071] Please refer to Figures 2 to 9 As shown, it shows the specific structure of a preferred embodiment of the present invention, including an insulating body 10, a plurality of terminals 20 and a shielding shell 30.

[0072] The insulating body 10 includes a base 11 and a tongue plate 12 which are integrally formed and connected, and a raised portion 13 extends upward from the top surface of the base 11, and the raised portion 13 extends upward from the shielding shell 30. A row of end spaces 101 are recessed between the raised portion 13 and the rear side surface of the base 11. A mounting plate 14 extends forward from one side of the front side surface of the base 11, and a step 141 is provided on the inner side surface of the mounting plate 14. The rear side surface of the shielding shell 30 is positioned against the step 141, so that it is more convenient to assemble the shielding shell 30.

[0073] The multiple terminals 20 are arranged on the insulating body 10, and the contact ends 201 of the multiple terminals 20 are exposed on the surface of the tongue plate 12, and the plug-in ends 202 of the multiple terminals 20 extend out on one side of the base 10. Specifically, the multiple terminals 20 include a fast charging terminal 21 and a plurality of conductive terminals 22 located on both sides of the fast charging terminal 21. The fast charging terminal 21 is inlay-molded on the insulating body 10, and the fast charging terminal 21 includes a flat contact portion 211, a main body 212, a connecting portion 213 and a plug-in portion 214 that are integrally molded and connected in sequence. The flat contact portion 211 is exposed on the upper surface of the front end of the tongue plate 12, and the flat contact portion 211 is formed by radially expanding and extending at the front end of the main body 212, that is, the width of the flat contact portion 211 is greater than the width of the main body 212, so as to facilitate electrical contact with the plug connector inserted from the outside. In addition, grooves 102 for reducing dielectric constant are provided on both sides of the upper surface of the tongue plate 12 corresponding to the flat plate contact portion 211 and on the bottom surface of the lower surface of the tongue plate 12 corresponding to the flat plate contact portion 211, thereby facilitating signal transmission.

[0074] The main body 212 is embedded in the tongue plate 12, and the upper surface of the front end of the tongue plate 12 is recessed with two fixed end holes 103 arranged at intervals in the longitudinal direction. The two fixed end holes 103 are arranged in a left-right staggered manner. The upper surface of the main body 212 is exposed to the two fixed end holes 103. When the insulating body 10 is injection molded, the fast charging terminal 21 is first placed in the mold cavity to form the insulating body 10. The mold needs to press the terminal to form the fixed end hole 103. The traditional fixed end holes 103 are arranged in a row of longitudinal intervals, which will hinder the flow of plastic during injection molding, and the product is often difficult to fill the mold. Now the arrangement of the fixed end holes 103 is changed to two rows of staggered, which can prevent the plastic from being diverted due to the fixed end holes 103 when flowing ( Figure 2 As shown), the insulating body 10 is prevented from being incomplete.

[0075] The connecting portion 213 is embedded in the base 11, and the connecting portion 213 has a multi-section bending structure. Specifically, the connecting portion 213 includes a first connecting segment 2131, a second connecting segment 2132 and a third connecting segment 2133; the first connecting segment 2131 extends obliquely downward from the rear end of the above-mentioned main body 212. The second connecting segment 2132 extends obliquely to the left at the rear end of the first connecting segment 2131. The third connecting segment 2133 extends obliquely upward from the left end of the second connecting segment 2132, and the above-mentioned plug-in portion 214 is integrally connected with the front side of the third connecting segment 2133. Through the arrangement of the first connecting segment 2131, the second connecting segment 2132 and the third connecting segment 2133, the connecting portion 213 is completely embedded in the base and the connecting portion 213 has a multi-section bending structure, which ensures the connection strength of the fast charging terminal 21 to the insulating body 10. The plug-in portion 214 extends out from the outer side of the above-mentioned mounting plate 14, making its structural layout more reasonable.

[0076] The insulating body 10 is provided with a plurality of terminal slots 104, and the plurality of conductive terminals 22 are inserted into the corresponding terminal slots 104. The front end of the terminal slot 104 has a hanging platform 15 that pre-presses the front end of the contact end of the conductive terminal. The front end of the contact end 201 of the conductive terminal 22 abuts against the hanging platform 15, so that the contact end 201 of the conductive terminal 22 is pre-pressed, the terminal height is consistent, and the pin breakage problem caused by the exposed terminal when the male and female are plugged in can be prevented, thereby making the connector more stable. The plug-in ends 202 of the plurality of conductive terminals 22 are arranged at intervals in the terminal row space 101. The arrangement of the terminal row space 101 facilitates the insertion of the plurality of conductive terminals 22, thereby improving the insertion efficiency, and the plug-in ends 202 of the conductive terminals 22 are hidden in the terminal row space 101, which is conducive to protection. Furthermore, the tail ends of the plug-in ends 202 of the plurality of conductive terminals 22 extend out in a row from the same outer side of the base 11 and the elevated portion 13. The provision of the elevated portion 13 increases the arrangement space of the tail ends of the plug-in ends 202 of the plurality of conductive terminals 22, thereby increasing the distance between the tail ends of the plug-in ends 202 of two adjacent conductive terminals 22, making the arrangement more reasonable, and reducing signal interference between two adjacent conductive terminals 22.

[0077] The shielding shell 30 is wrapped around the outer surface of the insulating body 10, and the shielding shell 30 has an insertion cavity 301 with an opening facing forward. A first plug plate 31 and a second plug plate 32 extend backward from the upper side of the rear end of the shielding shell 30, and correspondingly, the front and rear sides of the heightened portion 13 are penetrated with a first plug hole 105 and a second plug hole 106, and the first plug plate 31 is inserted into the first plug hole 105 for positioning. The second plug plate 32 is inserted into the second plug hole 106 for positioning, and an elastic card block 321 is punched and formed on the second plug plate 32, and correspondingly, a card slot 1061 is concavely provided on the bottom surface of the second plug hole 106, and the elastic card block 321 is inserted into the card slot 1061 for fixing, so that the shielding shell 30 and the insulating body 10 are more firmly connected. A third plug plate 33 extends backward from the lower side of the rear end of the shielding shell 30, and correspondingly, a third plug hole 107 is concavely provided on the bottom surface of the base 11, and the third plug plate 33 is inserted into the third plug hole 107 for positioning.

[0078] Two first pins 35 are punched out on one side of the rear end of the shielding shell 30, and a notch 302 is formed in the shielding shell corresponding to the positions of the two first pins punched out. The mounting plate 14 covers the notch 302, effectively preventing impurities from entering the insertion cavity 301. The two first pins 35 extend outward, and the first pins 35 are shaped like a harpoon, which is convenient for plugging. Two second pins 36 extend from the same side of the first pins 35, and the second pins 36 fit together up and down, so that the structural strength of the two second pins 36 is increased to prevent breakage and bending during plugging.

[0079] A sealing plate 40 is provided in the row end space 101, and the sealing plate 40 covers the plug-in ends 202 of the plurality of conductive terminals 22. Specifically, a positioning column 16 is convexly provided in the row end space 101, and correspondingly, a positioning hole 401 is penetrated through the inner and outer surfaces of the sealing plate 40, and the positioning column 16 is inserted into the positioning hole 401 for positioning. A positioning block 41 is convexly provided on the bottom surface of the sealing plate 40, and the front end of the positioning block 41 is in a slope shape for easy insertion. The bottom surface of the positioning block 41 is tightly plugged with the inner wall of the bottom surface of the row end space 101, and the top surface of the sealing plate 40 is in close contact and fixed with the inner wall of the top surface of the row end space 101, so that the sealing plate 40 is firmly installed in the row end space 101. A plurality of spacers 42 are convexly provided at intervals on the inner side surface of the sealing plate 40, and the plurality of spacers 42 are located between the corresponding adjacent plug-in ends 202 of the conductive terminals 22. The spacers 42 separate the two adjacent terminals, thereby effectively improving the crosstalk phenomenon generated when the signals of the two adjacent signal terminals are transmitted. The sealing plate 40 is provided to press the plug-in ends 202 of the plurality of conductive terminals 22 into the row end space 101, thereby better positioning and installing them. The sealing plate 40 covers the plug-in ends 202 of the plurality of conductive terminals 22 to form a first barrier wall, thereby effectively preventing impurities from entering the row end space 101 and improving the service life of the product.

[0080] The outer surface of the sealing plate 40 is covered with an EMI shielding sheet 50, which is installed on the shielding shell 30. Specifically, the EMI shielding sheet 50 is bent forward to form a fixed arm 51, and a buckle groove 501 is penetrated on the fixed arm 51. Correspondingly, a buckle block 34 is convexly provided on the surface of the shielding shell 30, and the buckle block 34 is buckled and fixed with the buckle groove 501, and a reinforcing rib 511 is convexly provided at the bending part of the fixed arm 51 to enhance the structural strength of the fixed arm. The EMI shielding sheet 50 effectively prevents electromagnetic waves from being exposed, thereby further enhancing the EMI shielding effect of the connector. At the same time, the EMI shielding sheet 50 forms a second barrier wall to further prevent impurities from entering the row end space 101.

[0081] The shielding shell 30 and the heightened portion 13 are wrapped with an outer shell 60, which forms a third barrier wall to further prevent impurities from entering the row end space 101. The inner wall of the outer shell 60 is provided with a first mounting structure 61, a second mounting structure 62 and a third mounting structure 63 at intervals. The first mounting structure 61 is fixedly matched with the shielding shell 30. Specifically, the first mounting structure 61 is a plurality of first plug-in blocks 61, which are arranged at intervals on the upper and lower inner walls of the front end of the outer shell 60, and the plurality of first plug-in blocks 61 are tightly plugged and fixed with the outer wall of the shielding shell 30. The second mounting structure 62 is fixedly matched with the heightened portion 13. Specifically, the second mounting structure 62 is a plurality of second plug-in blocks 62, which are arranged at intervals on the upper and lower inner walls of the rear end of the outer shell 60, and the plurality of second plug-in blocks 62 are tightly plugged and fixed with the outer wall of the heightened portion 13. The third mounting structure 63 is fixed with the EMI shielding sheet 50. Specifically, the third mounting structure 63 is a plurality of third plug-in blocks 63, which are arranged at intervals on the inner wall of the rear end of the housing 60, and are tightly plugged and fixed with the outer wall of the EMI shielding sheet 50. The left ends of the first plug-in block 61, the second plug-in block 62 and the third plug-in block 63 are all sloped guide structures. Through the arrangement of the first mounting structure 61, the second mounting structure 62 and the third mounting structure 63, the connector is tightly plugged and fixed with the housing 60 at multiple locations, so that the installation is more stable.

[0082] During assembly, first place the fast charging terminal 21 into the injection mold, injection mold the insulating body 10, and the fast charging terminal 21 and the insulating body 10 are inlaid together; then assemble the shielding shell 30 and the conductive terminal 22 onto the insulating body 10; then, assemble the sealing plate 40 to the corresponding position, and then cover the sealing plate 40 with the EMI shielding sheet 50; finally, insert the entire connector into the shell 60.

[0083] The design emphasis of the present invention is:

[0084] By changing the arrangement of the fixed end holes to two rows of staggered type, it can be prevented that the plastic will not be diverted due to the fixed end holes when flowing, thereby avoiding the situation where the insulating body is not full. By adding a heightening portion to the base, the arrangement space of the tail ends of multiple conductive terminal plug-in ends is increased, so that the distance between the tail ends of two adjacent conductive terminal plug-in ends is pulled larger, the arrangement is more reasonable, and the signal interference between two adjacent conductive terminals is reduced. By covering the row end space with a sealing plate, the sealing plate covers the plug-in ends of multiple conductive terminals to prevent them from being exposed, thereby effectively preventing impurities from entering the row end space and improving the service life of the product. At the same time, an EMI shielding sheet is covered outside the sealing plate to effectively prevent electromagnetic waves from being exposed, thereby further enhancing the EMI shielding effect of the connector. By providing a hanging platform at the front end of the terminal slot, the contact end of the conductive terminal is pre-pressed, the terminal bullet height has good consistency in size, and can prevent the pin breakage problem caused by the exposed terminal when the male and female are plugged in, thereby making the connector more stable. Through the arrangement of the sealing plate, EMI shielding sheet and shell, three barrier walls are formed, which effectively prevents impurities from entering the connector and improves the service life of the product. The upper surface of the tongue plate corresponds to both sides of the flat plate contact part and the lower surface of the tongue plate corresponds to the bottom surface of the flat plate contact part. The grooves that reduce the dielectric constant are concave, which is conducive to the transmission of signals. Multiple spacers are convexly arranged at intervals on the inner side surface of the sealing plate. The multiple spacers are located between the corresponding adjacent conductive terminal plug-in ends. The spacers separate the two adjacent terminals, thereby effectively improving the crosstalk phenomenon generated when the signals of the two adjacent signal terminals are transmitted.

[0085] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
