The features of this invention which are believed to be novel are set forth with particularity in the appended claims. The invention, together with its objects and the advantages thereof, may be best understood by reference to the following description taken in conjunction with the accompanying drawings, in which like reference numerals identify like elements in the figures and in which:
Reference will now be made in detail to the preferred embodiment of the present invention.
Referring to
The insulative housing 1 is generally cuboid shaped and includes a top wall 11 opposite to the mounting wall 12, a front wall 13 perpendicular to the top and mounting walls 11, 12, and a rear wall 14 opposite to the front wall 13. A pair of first and second receiving cavities 15, 16 are defined in the front wall 13 for respectively receiving the first and the second connector components 2, 3 therein. The insulative housing 1 comprises a tongue plate 151 horizontally extending forwardly into the first receiving cavity 15 with a plurality of passageways 152 recessed in a top and a bottom faces thereof. The insulative housing 1 has a supporting block 17 extending into the first receiving cavity 15 for abutting against the first connector component 2. The rear wall 14 comprises a plurality of vertical flanges 141 and a plurality of vertical slots 142 formed by the vertical flanges 141, wherein each slot 142 is in communication with the corresponding passageways 152. The rear wall 14 further comprises a concavity 144 and a plurality of engaging apertures 143 disposed on opposite lateral sides thereof. The concavity 144 and the engaging apertures 143 communicate with each other for fitting with the holder 4.
The first connector component 2 comprises a plurality of first contacts 21 retained in the tongue plate 151 and a metal shell 22 received in the first receiving cavity 15 to enclose the tongue plate 151. Each of the first contacts 21 comprises a contact portion 211 received in the passageways 152 and a right-angle bent tail 213 received in the slots 142 of the rear wall 14 in a staggered manner. The supporting block 17 abuts against the metal shell 22 to provide enough engaging force so that the metal shell 22 can be stably retained in the first receiving cavity 15. The first connector component 2 together with the tongue plate 151 forms a first connector which is a standard A-type IEEE-1394 (Institute of Electrical and Electronics Engineers) connector in the preferred embodiment. The second connector component 3 in the preferred embodiment is a standard B-type IEEE-1394 connector. So the detailed description of the first and second components 2, 3 is omitted hereinafter.

In assembly, the holder 4 is assembled to the rear wall 14 of the insulative housing 1. The mating portion 41 is received in the concavity 144 with the projections 412 retained in the corresponding engaging apertures 143 to restrain movement in a front-to-back direction. The vertical protrusions 411 are received in the slots 142 of the insulative housing 1 for abutting against complementary right-angle bent tails 213. Thus, the right-angle bent tails 213 are snugly sandwiched between the insulative housing 1 and the holder 4. An area of the top portion 42 and the top wall 11 is smaller than that of the bottom portion 43 and the mounting wall 12 so that the insulative housing and the holder 4 can be stably mounted on the PCB for mating with corresponding plugs.
The peripheral metal shield 5 includes a front shield 51 and a slant rear shield 52 fixed to the front shield 51. The front shield 51 comprises a mating wall 511 along the front wall 13 of the insulative housing 1, a pair of trapezia shaped side walls 513 backwardly extending from lateral edges of the mating wall 511 and a top wall 512 backwardly extending from a top edge of the mating wall 511. The mating wall 511 defines a pair of first and second openings 5111, 5112 for the first and second components 2, 3 exposed therethrough. The top wall 512 defines a pair of first outstandings 5122 formed at a free end thereof. Each side wall 513 has an upper edge shorter than a lower edge and defines a plurality of second outstandings 5131 thereof. A plurality of grounding legs 5132 extend downwardly from the lower edge of each side wall 513 for initial board retention. The rear shield 52 comprises a main portion 521, a top flap 522 extending forwardly from a top edge of the main portion 521 and a pair of incontinuous side flaps 523. The top flap 522 defines a pair of first holes 5221 for receiving the first outsandings 5122. Each side flap 523 defines a plurality of second holes 5231 for mating with the second outstandings 5231. The rear shield 52 abuts against the rear portion 44 of the holder 4 to further ensure a reliable connection between the insulative housing 1 and the holder 4.
The spacer 6 is attached to both the mounting wall 12 and the bottom portion 43 of the holder 4. The spacer 6 comprises a body 61 and a rear tail 64 integrally connecting with the body 61. The body 61 comprises a plurality of arms 62 extending upwardly for locking with plural depressions 121 of the mounting wall 12 and a plurality of through holes 63 for the right-angle bent tails 213 extending therethrough. The body 61 comprises a front edge (not labeled) reaching the front wall 13 of the insulative housing 1. The rear tail 64 reaches a rear of the bottom portion 43 of the holder 4.
In use, the spacer 6 is mounted on the PCB. When the corresponding plug is inserted or pulled out from the electrical connector assembly 100, the rear tail 64 of the spacer 6 abuts against the PCB and the bottom portion 43, thereby providing stable retaining force to prevent the electrical connector assembly 100 from inclining. As a result, the mating characteristic of the electrical connector assembly is improved.
It is easy to be understood that the electrical connector assembly 100 may not set the spacer 6. In that case, the bottom portion 43 of the holder 4 can be disposed coplanar with the mounting wall 12 of the insulative housing 1. The bottom portion 43 as well as the mounting wall 12 is mounted on the PCB. When the corresponding plug is inserted or pulled out from the first and second connector components 2, 3, the bottom portion 43 extending beyond the insulative housing 1 can abut against the PCB to provide enough retaining force for prevent the electrical connector assembly 100 from inclining. It is to be understood, however, that even though numerous, characteristics and advantages of the present invention have been set fourth in the foregoing description, together with details of the structure and function of the invention, the disclosed is illustrative only, and changes may be made in detail, especially in matters of number, 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.
