DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Reference will now be made in detail to the preferred embodiment of the present invention.
Referring to FIGS. 1-4, the instant invention discloses a cable connector assembly 1000 comprising a cable 300 and a connector 100 connecting to the cable 300. The connector 100 includes a contact module 1 and a shell 2 installed at the outside of the contact module 1. The shell 2 defines an opening 213 facing forwardly and a hole 210 facing backwardly for the cable 300 passing through, the elasticity opening 213 running through said base 21 in said transverse direction for said contact module 1 forwardly extending through and that also could enclose the thickness of contact module 1 from the initial size of the first to the second. The hole 210 allowing the cable 300 to go through, and when the end of the cable 300 connecting with the contact module 1, the opening 213 open to the second size to make the contact module 1 enter into the shell 2 then reset to the first size.
The contact module 1 includes a printed circuit board 11 positioned horizontally, a plurality of conductive contacts 13 installed in the front of the printed circuit board 11 and a tongue 10 enclosing the front of the contact 13 and forwardly extending out of the opening 213, the tongue 10 formed out of the contact 13 within the present embodiment; Obviously, it can be inserted into the tongue 10 formed singularly from backward to the forward, but whatever the manners of fixing the tongue 10 and the contact 13, the contact 13 is required to expose on the tongue 10 for contacting with the docking connector (not shown). The contact module 1 also includes a pair of supporting portions 14, preferably of magnetic material, fixed on the printed circuit board 11, a filling portion 12 made from insulative material enclosing at the location for protection where the cable 300 connects with the printed circuit board 11, a luminous element 16 mounted to the printed circuit board 11 and light guiding member 15 located beside said luminous element 16. The supporting portions 14 are located at two sides of the contact module 1 for internally sustaining the shell 2.
FIGS. 5-14 show the detailed structure of the contact module 1 with the associated cable which is similar to the structures shown in U.S. Pat. No. 9,257,801. The contact module 1 includes a printed circuit board 11 with a front region on which the contact set 502 including the contacts 13 and the associated insulator 504, is mechanically and electrically mounted, and a rear region on which the wires 302 of the cable 300 are soldered. The front region of the printed circuit board 11 including the contact sets 502 is received within a metallic enclosure 510 and an insulative filling 520 is applied between the enclosure 510 and the printed circuit board 11 to retain the enclosure 510 with regard to the printed circuit board 11 so as to form the tongue 10. An inner molding 540 is applied upon the rear region of the printed circuit board 11 to protect the A pair of shields 530 commonly cover the inner molding 540, and the filling portion 12 encloses the pair of shields 530 and further invades a space between the shields 530 and the inner molding 540 and the associated printed circuit board 11.
The shell 2 includes base 21 extending in a transverse direction and a pair of side covers 22, 23 assembled to two sides of the base 21 in the transverse direction. The base 21 is in a cylindrical shape except the opening 213, the base 21 including an insulating layer 211, shield layer 212 assembled in the insulating layer 211 and a pair of cavities 214 formed at two sides thereof, the side cover 22 including an insulating layer 221 and shield layer 222 assembled in the insulating layer 221, the side cover 22 also including an insulating layer 231 and shield layer 232 assembled in the insulating layer 231. Therefore, when the base 21 is sealed by the side cover 22,23 from the two sides thereof, the shielding layer 212,222,232 on the base 21 and the side cover 22,23 form a better shielding space surrounding the contact module 1. Said shield layer 212 of the base 21 defines a slot 2121 for accommodating said light guiding member 15, and said insulating layer 212 is made of transparent material and covering said slot 2121 for displaying light from the luminous element 16 guided by said light guiding member 15.
The side cover 23 includes a vertical portion 2211 engaging with one side of the respective cavity 214, and a part of closed portion 223 transversely extending from the vertical portion 2211 and toward the tongue 10 to seal one side of the opening 213 except for exposure of the tongue 10. The side cover 23 includes a vertical portion 2311 engaging with other side of the respective cavity 214, and a part of closed portion 233 transversely extending from the vertical portion 2311 and toward the tongue 10 to seal other side of the opening 213 except for exposure of the tongue 10. In other words, the closed part 223 and the closed part 233 extend from the opening 213 of the two ends of the base 21 to the position of the tongue 10 of the contact module 1 to seal the opening 213 of two sides of the tongue 10.
In this embodiment, all the shielding layer 212,222,232 is made from metal sheets, and the insulating layer 211,221,231 is formed from insulating material. The base 21 is inserted into insulating layer 211 by a manual shield layer 212 to get, the side cover 22 is inserted into insulating layer 221 by a manual shield layer 222 to get, and the side cover 23 is inserted into insulating layer 231 by a manual shield layer 232 to get, therefore, the shielding layer 212,222,232 is assembled to inside of the insulating layer. Obviously, in another preferred embodiment, the insulating layer 211,221,231 may be injected molding with the shielding layer 212,222,232 made from metal sheets also could achieve the same shielding effect.
In this embodiment, the cable 300 is welded on the back-end of the printed circuit board 11, preferably, the end of cable 300 also cladding a stress relief member (unnumbered), which could fill the gap around the cable 300 in the hole 210, so that the cable connector assembly 1000 has a better shielding appearance.
The feature of the invention is to provide the specific shell upon the contact module 1 and the cable 300 and the corresponding assembling process as follows in the following sequence. Before the contact module 100 is assembled with the cable 300, the shell 2 is firstly loosely pre-assembled with the cable 300 through the hole 210 to expose the front end of the cable 300. The printed circuit board 11 and the enclosure 510, the contact set 502 and the insulative filling 520 associated therewith on the front region, is assembled to cable 300 by soldering the wires 302 upon the rear region of the printed circuit board 11. The inner molding 540 is applied upon the rear region to protect the connection between the wires 302 and the printed circuit board 11. The pair of shields 530 are assembled upon the enclosure 510. The filling portion 12 is molded upon the shields 530, the cable 300, the printed circuit board 11 and the inner molding 540. The shell 2 is successively moved forwardly in the front-to-back direction to have the opening 213, via flexibility/expandability thereof in the vertical direction perpendicular to both the transverse direction and the front-to-back direction, pass over the shell 2 and have the tongue 10 extend forwardly therefrom. The supporting portions 14 and the light guiding member 15 are assembled into two opposite ends of the interior of the base 21 and by two sides of the printed circuit board 11. The side covers 22 and 23 are assembled to the base 21 to seal the interior of the base 21. Eventually, the cable connector assembly has the tongue 10 and the cable 300 extend outwardly from two sides/ends of the shell 2 along the front-to-back direction, i.e., along the front-to-back line.
While a preferred embodiment of the present invention has been shown and described, equivalent modifications and changes known to persons skilled in the art according to the spirit of the present invention are considered within the scope of the present invention as described in the appended claims.
