Abstract

An electrical connector includes a shield (1), a flexible printed circuit (2) and a support element (4). The shield has a receiving space (10) and a pair of sidewalls (12). Each sidewall defines thereon a pair of open slots (125) to form a body portion (121) disposed above said open slots. Each body portion has a pair of opposite free ends projecting toward the receiving space to form a pair of resilient portions for standing against the electrical element. The flexible printed circuit is received in the receiving space for electrically connecting the electrical element. The support element upholds the flexible printed circuit for maintaining an electrical connection between the flexible printed circuit and the electrical element.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Reference will now be made to the drawing figures to describe the present invention in detail. Referring to FIGS. 1-4, an electrical connector in accordance with the present invention is adapted for firmly fastening an electrical element. The electrical element referred to in this embodiment is a camera module 3. The electrical connector comprises a shield 1 defining a receiving space 10, a support element 4 and a flexible printed circuit 2 mounted in the receiving space 10 of the shield 1 in sequence.

The shield 1 comprises a bottom wall 11, a primary wall 13, a pair of opposite sidewalls 12 and an end wall 14 interconnected together to thereby define the receiving space 10. The bottom wall 11 includes a pair of protrusions 110 protruding upwardly from a center portion of an inner surface thereof, and a plurality of slots 111 symmetrically defined along two opposite edges thereof. The primary wall 13 has a cutout 130 defined in a middle portion thereof for partial extension of the flexible printed circuit 2. A pair of open slots 125 are defined on the sidewall 12 to divide it into an body portion 121 and a lower base portion 120. The pair of open slots 125 extend obliquely upwardly and then horizontally so that the body portion 121 is substantially shaped as a triangle. Each body portion 121 has a pair of opposite free ends projecting toward the receiving space 10 to form a pair of resilient portions 123 for standing against the camera module 3. The sidewall 12 has a connection portion 122 formed between lower ends of the pair of open slots 125 and connecting the body portion 121 to the lower base portion 120. Referring to FIG.4, each resilient portion 123 further comprises a fixing portion 1230 projecting toward the receiving space for standing against the camera module 3 and a first guiding portion 1231 formed above the resilient portion 123 for guiding the camera module 3. The end wall 14 includes an anti-mismating indentation 140 defined at a center portion thereof for receiving an anti-mismating protrusion 320 formed on the camera module 3. The primary wall 13 and the end wall 14 are respectively formed with a pair of second guiding portions 105 extending outwardly from a top portion thereof for guiding the camera module 3.

The support element 4 is of a fishbone configuration and comprises a main portion 410 disposed above the bottom wall 11 of the shield 1, a plurality of flexible portions 411 upwardly extending from opposite sides of the main portion 410 for upholding the flexible printed circuit 2. The main portion 410 has a pair of receiving holes 4100 for receiving corresponding protrusions 110 of the bottom wall 11. When the symmetrical flexible portions 411 are pressed downwardly by the camera module 3, the flexible portions 411 can be received in the slots 111 of the bottom wall 11.

The flexible printed circuit 2 comprises a first portion 21 and a second portion 22. The first portion 21 is located in the receiving space 10, with a top surface thereof contacting with the camera module 3 and a bottom surface thereof being resisted against by the flexible portions 411 of the support element 4. The second portion 22 extends outwardly though the cutout 130 for electrically connecting to a printed circuit board (not shown).

The camera module 3 has a side face 31, a primary face 33 and an end face 32. Each side face 31 has a protrusion 310 projecting outwardly therefrom. The end face 32 is formed with an anti-mismating protrusion 320.

In assembling the electrical connector, the support element 4 and the flexible printed circuit 2 are assembled in the receiving space 10 in sequence. The support element 4 is inserted into the shield 1 in a top-to-bottom direction, with the pair of protrusions 110 of the bottom wall 11 of the shield 1 being received in the corresponding receiving holes 4100 of the main portion 410 of the support element 4.

When the camera module 3 is guided in, the fixing portions 1230 of the pair of sidewalls 12 are pressed and deflected outwardly. When the camera module 3 is completely inserted in, the fixing portions 1230 abut against the protrusions 310. The anti-mismating protrusion 320 is received in the anti-mismating indentation 140. The support element 4 provides sufficient resilient force for tightly connecting the camera module 3 with the flexible printed circuit 2.

The body portion 121 is connected to the lower base portion 120 via the connection portion 122, which is formed between lower ends of the pair open slots 125 and therefore has a width much smaller than that of the body portion 121. Therefore, the body portion 121 is flexible and the resilient portions 123 formed thereon would provide sufficient resilient force to firmly fasten the camera module 3 in the receiving space 10.

It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
