BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a thin connector, and particularly to a thin connector which is assembled on a printed circuit board (PCB) for communicating with a Liquid Crystal Display (LCD) and which has simplified structure and shields from interference.
2. Related Art
A connector, which is assembled on a mainboard for communicating with LCD, is always required to transfer numerous data. Correspondingly, such a connector has a number of conductive terminals thereon. The connector is often required to have small size, so the conductive terminals have to be mounted closely. However, conductive terminals being mounted closely is most likely to produce cross talking, resulting in unreliable signal transmission.
Moreover, the connector usually has a metal shield around an insulative housing for avoiding external interference thereby assuring transmission quality; however, a height of the insulative housing is limited to a required height due to current moulding processing, and plus the metal shield cover outside, which cause the height of the connector unable to be minimized.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a thin connector having reliable shielding performance and having simplified structure and low profile.
To achieve the above-mentioned objects, the thin connector of the present invention comprises an insulative housing, a plurality of conductive terminals received in the insulative housing and a shell shielding the insulative housing and the conductive terminals. The insulative housing defines assembling holes therein and receiving space adjacent to the assembling holes and toward the mating wall.
The shell forms assembling arms on both sides thereof for corresponding to the assembling holes of the insulative housing. The assembling arms have front portions interferentially assembled inside the assembling holes of the insulative housing. Assembling grooves are defined in rear portions of the assembling arms for locking with a mating connector. The receiving space and the shell define a locking groove for locking with the mating connector.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
With reference to FIG. 1, a thin connector 1 of the present invention comprises an insulative housing 2, a plurality of conductive terminals 3 and a shell 4. The insulative housing 2 is substantially rectangular and has long sides and short sides. A mating wall 20 and a connecting wall 21 are respectively located at long sides opposite to each other. The insulative housing 2 further forms a top wall 22 at a top, a bottom wall 23 at a bottom, and a pair of side walls 24, 25 at both sides, which are between the mating wall 20 and the connecting wall 21. Engaging blocks 26 respectively extend outwardly from opposing ends of the connecting wall 21. Each engaging block 26 defines an upright and rectangular assembling hole 260, and receiving space 27 toward the mating wall 20 and adjacent to the assembling hole 260. An opening 201 (shown in FIG. 4) is defined longitudinally through the mating wall 20 for accommodating a mating connector (not shown). A plurality of passageways 202 (shown in FIG. 5) is transversely defined through the mating wall 20 and the connecting wall 21 for receiving the conductive terminals 3 therein. A plurality of plug holes 203 is transversely defined below the passageways 202 and is spaced equally apart from each other. Positioning notches 28 are respectively defined in the insulative housing 2 and adjacent the side walls 24, 25. The conductive terminals 3 are received in the passageways 202, and each conductive terminal 3 has a contact portion 30, a soldering portion 32 and an interferential portion 31 between the contact portion 30 and the soldering portion 32. The soldering portion 31 bends appropriately for surface mounting.
In combination with FIG. 5, the shell 4 has a top shielding wall 40 at a top, a bottom shielding wall 41 at a bottom, a pair of side shielding walls 42, 43 on both sides, assembling arms 44 on both sides for corresponding to the assembling holes 260, and ground pins 45. The top shielding wall 40 and the side shielding walls 42, 43 are respectively for shielding the top wall 22 and the side walls 24, 25 of the insulative housing 2. The top shielding wall 40, the side shielding walls 42, 43 together with the receiving space 27 define a locking groove (not labeled) for locking with the mating connector. The bottom shielding wall 41 is mounted inside the insulative housing 2 and forms a plurality of partitions 46 on a front side thereof for fitting to the plug holes 203. The number of the partitions 46 corresponds to that of the plug holes 203. Each partition 46 forms anchors 461 at opposite edges of a front end thereof for interferentially engaging with a plug hole 203. Referring to FIG. 2, the assembling arms 44 are integrally formed with and extend outwardly from the top shielding wall 40, bend substantially perpendicularly to reach the bottom shielding wall 41 and then perpendicularly bend and extend to cover the side shielding walls 42, 43. Each assembling arm 44 has a front portion 441 and a rear portion 442. Protuberances 443 are formed on the front portion 441 and are assembled inside the assembling holes 260 of the insulative housing 2. The rear portion 442 defines assembling grooves 444 therein for locking with the mating connector. The grounding pins 45 extend from the bottom shielding wall 41 of the shell 4, corresponding to the positioning notches 28, and have soldering portions 451 bending appropriately for facilitating surface mounting. A pair of soldering tails 47 respectively extends outwardly and bends perpendicularly from the side shielding walls 42, 43 for facilitating surface mounting. Three springy plates 48 (shown in FIG. 2) are formed on the bottom shielding wall 41 for firmly mating with the mating connector.
Further referring to FIGS. 1–7, during assembly, the conductive terminals 3 are firstly inserted into the passageways 202 of the insulative housing 2. The shell 4 is mounted onto the opening 201 of the insulative housing 2. The protuberances 443 of the assembling arms 44 are assembled inside the assembling holes 260 of the insulative housing 2, as shown in FIG. 6. The partitions 46 are accommodated in the plug holes 203, as shown in FIG. 7. The overall height of the thin connector 1 is diminished because the bottom shielding wall 41 of the shell 4 is received inside the insulative housing 2. The partitions 46 shield below the contact portions 30 of the conductive terminals, and therefore the conductive terminals 3 are entirely shielded from cross talking. The capacity of the thin connector 1 increases to achieve impedance match for stable signal transmission. Moreover, the assembling grooves 444 of the assembling arms 44 latch with the mating connector, effectively avoiding disengagement.
It is understood that the invention may be embodied in other forms without departing from the spirit thereof. Thus, the present examples and embodiments are to be considered in all respects as illustrative and not restrictive, and the invention is not to be limited to the details given herein.
