2. Description of Related Art
Nowadays, cable connector assemblies are widely used in an electronic equipment, especially for transmitting power, and the performance of the cable connector assembly directly impacts on the entire electronic equipment whether can normally run.
CN patent No. 201130761Y issued to Tang on Oct. 8, 2008 discloses a cable connector assembly, the cable connector assembly comprises an insulated housing, a flexible printed circuit board, a LED element and a light transmission member equipped on the flexible printed circuit board, and a cover enclosing the aforementioned elements. The flexible printed circuit board encloses the insulated housing, and the LED element is located on an outer side of the flexible printed circuit board, light from the LED element can pass through the light transmission member. The insulated housing is received in the cover, there will be a gap between the insulated housing and the cover inevitably, the light from the LED element will be diffused around, and the light through the gap on a front end of the insulated housing will pass through a receiving space of the cover, and the rest light passing through the light transmission member will be weaken, so it may be difficult for users to observe actual working status of the cable connector assembly.
Correspondingly, it is desired to have a cable connector assembly with improved shielding member to address the problems stated above.
Accordingly, an object of the present invention is to provide a cable connector assembly having a sticky film to shield a gap between an insulative housing and a cover.
In order to achieve the above-mentioned object, a cable connector assembly in accordance with the present invention comprises an insulative housing, a plurality of contacts received in the insulative housing, a cable electrically connected with the contacts, a light guiding member, a cover enclosing the insulative housing and the cable, a LED covered by the light guiding member and a pair of films located between the LED and one side of the insulative housing. And the films are shielding a gap between the insulative housing and the cover.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawing figures to describe the present invention in detail.

The conductive contacts 3 consist of a pair of ground contacts 31, a pair of power contacts 32 located between the pair of ground contacts 31 and a center detect contact 33 located between the pair of power contacts 32. Each contact 3 is of a POGO Pin type, that is to say, there is a spring (not shown) inside the contact 3, thus, when mating, front contacting portion 35 of the contact 3 can be pressed to rearward move along the mating direction. Each ground contact 31 comprises the column-shape contacting portion 35 with a relatively small diameter and capable of being compressed, a column-shape media portion 36 with a relatively large diameter, and an end portion 37 formed at rear end of the media portion 36 with a column-shape and smaller diameter. An expansion portion 360 is protruding outwards from an exterior surface of each media portion 36. The power contact 32 has the same structure as that of the ground contact 31 except the contacting portion 35 thereof has a length shorter than that of the ground contact 31. Thus, the ground contacts 31 will firstly mate with re complementary connector and lastly disengage from the complementary connector for assuring safe power and signal transmission. The detect contact 33 has the same structure as that of the power contact 32 except each portion thereof has a smaller diameter than that of the power contact 32.
The linking member 4 is located outside the insulative housing 2, and includes a first linking portion 41 and a second linking portion 42 below the first linking portion 41. The first linking portion 41 and the second linking portion 42 have the same configuration with each other and are opposite to each other. The first linking portion 41 comprises a main portion 410, a first soldering portion 411 extending horizontally from one side of the main portion 410 and an ear portion 412 extending from another side of the main portion 410 and located on a plane vertical to the main portion 410. The first soldering portion 411 is parallel to the main portion 410 and lower than the main portion 410. The ear portion 412 defines a second mounting hole 4120 aligned with the first mounting hole 231 of the insulative housing 2 along the mating direction. The main portion 410 has a plurality of positioning holes 4101, a pair of first curving portions 4102 are bent downwards from a back end thereof and a third curving portion 4104 is bent upwards from a front end thereof, and each first curving portion 4102 defines a first soldering hole 4103. The first curving portions 4102 are parallel to the third curving portion 4104 and vertical to the main portion 410.
