(20) The description will be made as to the embodiments of the present invention in conjunction with the accompanying drawings in FIGS. 1-13. In accordance with the purposes of this invention, as embodied and broadly described herein, this invention, in one aspect, relates to a cable connector assembly.

(21) As shown in FIG. 1 to FIG. 3, a cable connector assembly 100 according to a first embodiment of the present invention is provided. The cable connector assembly 100 includes: a body 1; a plurality of terminals 2 accommodated in the body 1, the terminals 2 including a plurality of signal terminals 21 and a plurality of non-signal terminals 22, each signal terminal 21 having a first wire-bonding end 211 that horizontally extends forward outside the body 1, and each non-signal terminal 22 having a second wire-bonding end 221 that extends outside the body 1 along a same direction as the first wire-bonding end 211; a shielding sheet 3 arranged on the body 1, the shielding sheet 3 having a soldering portion 31 which extends outside the body 1 along the same direction as the first wire-bonding end 211; a signal cable 4 having a first core 41, a first insulating layer 42 wrapping on the first core 41, and a shielding layer 43 wrapping on the first insulating layer 42, the first core 41 having a first soldering portion 411 that is exposed from the first insulating layer 42 and configured to be soldered to the first wire-bonding end 211; and a non-signal cable 6, having a second core 61 and a second insulating layer 62 wrapping on the second core 61, and the second core 61 having a second soldering portion 611 that is exposed from the second insulating layer 62 and configured to be soldered to the second wire-bonding end 221.

(22) As shown in FIG. 4 and FIG. 5, the number of signal terminals 21 is six, and they are arranged as three terminal pairs 21a. The shielding sheet 3 has three soldering portions 31 which respectively correspond to the first wire-bonding ends 211 of the three terminal pairs 21a. The non-signal terminals 22 include two grounding terminals 22a, and the shielding sheet 3 has two soldering portions 31 which respectively correspond to two second wire-bonding ends 221 of the two grounding terminals 22a. Corresponding to the six signal terminals 21, the number of the first cores 41 is six, arranged as three pairs, which include two pairs of high-speed signal cores 41a and a pair of USB 2.0 cores 41b. The non-signal cables 6 include two grounding cables 6a, two power cables 6b and two reserved cables (not numbered). A diameter of a power core 61b of each power cable 6b is greater than a diameter of each high-speed signal core 41a. The diameter of each high-speed signal core 41a is greater than or equal to a diameter of a grounding core 61a of each grounding cable 6a. The diameter of each grounding core 61a is greater than or equal to a diameter of each USB 2.0 core 41b. The rear ends of the six first cores 41 are all located behind the rear ends of the second cores 61. In other embodiments, the diameter of each high-speed signal core 41a can be equal to the diameter of the grounding core 61a of each grounding cable 6a, and the diameter of each grounding core 61a can also be equal to the diameter of each USB 2.0 core 41b.

(23) As shown in FIG. 4 to FIG. 6, the shielding layer 43 is electrically connected with the soldering portion 31 to form a contact area 5, and the contact area 5 is soldered by laser soldering, thereby fixing the shielding layer 43 to the soldering portion 31. The non-signal cables 6 include two grounding cables 6a and two power cables 6b. The second insulating layers 62 of all of the non-signal cables 6 are located in front of the contact areas 5. Since laser soldering can result in high temperature, such arrangement staggers the second insulating layers 62 and the contact areas 5 in tandem. Consequently, in the process of soldering the contact areas 5 by laser soldering, the second insulating layers 62 of the non-signal cables 6, such as the grounding cables 6a or the power cables 6b, near the contact areas 5 will not be melted by the high temperature to expose the second cores 61 which is supposed to be wrapped therein, resulting in the risk of short-circuiting or electrical leakage. In other embodiments, it is reasonable that the rear ends of the second insulating layers 62 are flush with the front end of the contact areas 5. The rear ends of the second cores 61 are flush with the rear ends of the shielding layers 43, a third insulating layer 44 wraps on the shielding layer 43, and the rear ends of the third insulating layers 44 are flush with the rear ends of the second insulating layers 62. The reason for such arrangement is that the first insulating layer 42 of the signal cable 4 is usually provided with an exposed section 421, in order to prevent the first core 41 from being short-circuited with the shielding layer 43. However, because the exposed sections 421 are normally flush with the second cores 61, in the process of laser soldering of the second cores 61, the exposed sections 421 can also be easily melted by heat to result in the risk of short-circuiting or electrical leakage. It should be noted that in other embodiments, the same objective can be achieved when the rear ends of the second cores 61 are located in front of the rear ends of the shielding layers 43. Similarly, the intention of the present invention can also be met when the rear ends of the third insulating layers 44 are located in front of the rear ends of the second insulating layers 62.

(24) As shown in FIG. 2 and FIG. 7, the body 1 has a base 11, the base 11 extends forward to form three first extending portions 12 and four second extending portions 13 respectively separated by the three first extending portions 12. The terminals 2 are arranged on the base 11 symmetrically in an upper row and a lower row. The first wire-bonding ends 211 are exposed on upper and lower surfaces of the first extending portions 12, and the second wire-bonding ends 221 are exposed on upper and lower surfaces of the second extending portions 13. The shielding sheet 3 is arranged between the terminals 2 in the upper row and the lower row. The three soldering portions 31 are sandwiched between the first wire-bonding ends 211 of the six terminal pairs 21a in the upper row and in the lower row, respectively. The front ends of the second wire-bonding ends 221 of the grounding terminals 22a are located between the front ends of the first wire-bonding ends 211 and the front ends of the second wire-bonding ends 221 of the power terminals 22b. Meanwhile, the front ends of the first wire-bonding ends 211 are flush with the front ends of the first extending portions 12, and the front ends of the second wire-bonding ends 221 are flush with the front ends of the second extending portions 13. The shielding sheet 3 also has two soldering portions 31 which are sandwiched between the second wire-bonding ends 221 of the four grounding terminals 22a in the upper row and in the lower row, respectively. The front ends of the two soldering portions 31 partially protrude outside the second extending portions 13. The grounding cores 61a are soldered to the grounding terminals 22a by laser soldering, and the grounding cores 61a can also be soldered to the two soldering portions 31 at the same time.

(25) As shown in FIG. 8 to FIG. 10, a cable connector assembly 100 according to a second embodiment of the present invention is provided. The second embodiment differs from the first embodiment in that the two second wire-bonding ends 221 of the two grounding terminals 22a in the same row are electrically connected through a connecting frame 222, and the connecting frame 222 and the two second wire-bonding ends 221 are integrally provided, thus enhancing the grounding performance of the grounding terminals 22a.

(26) As shown in FIG. 11 to FIG. 13, the connecting frame 222 has a bending portion 2221. The bending portion 2221 is electrically connected with the three soldering portions 31 corresponding to the terminal pairs 21a. The shielding layers 43 are electrically connected with the connecting frame 222. Since the shielding layers 43 are also soldered to the three soldering portions 31 by laser soldering, the bending portion 2221, the three soldering portions 31 and the shielding layers 43 are electrically connected with one another. Certainly, any two of the three components can be soldered to be connected with each other, so that the grounding terminals 22a, the shielding sheet 3 and the shielding layers 43 are electrically conductive with each other, forming an integral shielding structure (not numbered), thereby considerably enhancing the shielding effect of the cable connector assembly 100. This also makes the front ends of the second wire-bonding ends 221 be not flush with the front ends of the second extending portions 13. Moreover, in the present embodiment, the front ends of the first wire-bonding ends 211 are located behind the front ends of the first extending portions 12. The other structures in the second embodiment are identical with those in the first embodiment, and therefore the descriptions thereof are not elaborated herein.

(27) In the above-mentioned two embodiments, the shielding sheet 3 horizontally protrudes forward outside the body 1. In other embodiments, the shielding sheet 3 can be bent by 90 degrees or other angles to protrude outside the body 1. Correspondingly, the first wire-bonding ends 211 and the second wire-bonding ends 221 can be modified in the same way. In such ways, arrangements can be customized according to different application requirements, thereby allowing the cable connector assembly 100 of the present invention to have good adaptability to spatial conditions.

(28) A cable connector assembly according to certain embodiments of the present invention have the following beneficial advantages:

(29) 1. The shielding layer 43 is electrically connected with the soldering portion 31, thereby enhancing the grounding effect of the cable connector assembly. The contact area 5 and the second insulating layer 62 are staggered in tandem, such that in the subsequent process of laser soldering of the contact area 5, the second insulating layer 62 is not damaged, thereby ensuring the insulating effect, and avoiding from short-circuiting. Moreover, the second soldering portion 611 is flush with the shielding layer 43, such that the subsequent processes of laser soldering of the second soldering portion 611 and the second wire-bonding end 221 as well as laser soldering of the shielding layer 43 and the soldering portion 31 can be continuously performed, thus increasing the efficiency of soldering.

(30) 2. The grounding core 61a is soldered to both the second wire-bonding end 221 of the grounding terminal 22a and the soldering portion 31, so that the shielding layer 43 is electrically conductive with the grounding terminal 22a and the grounding core 61a through the shielding sheet 3, thus enhancing the grounding effect of the cable connector assembly 100.

(31) 3. The connecting frame 222 encloses the first wire-bonding ends 211 and second wire-bonding ends 221 of all of the terminals 2, and the bending portion 2221 is electrically connected with the soldering portions 31, so that the grounding terminals 22a are directly conductive with the shielding sheet 3. The shielding layers 43 are soldered to the bending portion 2221, thus enhancing the shielding effect of the cable connector assembly 100, and alleviating crosstalk interference.

(32) 4. The second soldering portions 611 and the exposed sections 421 are staggered in tandem, so that heat generated in the process of laser soldering of the second soldering portions 611 does not melt the exposed sections 421 to cause the portions of the first cores 41 that are supposed to be wrapped to be exposed, thus preventing the risk of short-circuiting caused thereby.

(33) The foregoing description of the exemplary embodiments of the invention has been presented only for the purposes of illustration and description and is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Many modifications and variations are possible in light of the above teaching.

(34) The embodiments are chosen and described in order to explain the principles of the invention and their practical application so as to activate others skilled in the art to utilize the invention and various embodiments and with various modifications as are suited to the particular use contemplated. Alternative embodiments will become apparent to those skilled in the art to which the present invention pertains without departing from its spirit and scope. Accordingly, the scope of the present invention is defined by the appended claims rather than the foregoing description and the exemplary embodiments described therein.
