## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a high profile electrical connector.
2. Description of the Related Art
U.S. Pat. No. 6,688,895 issued on Feb. 10, 2004, discloses an electrical connector including a longitudinal insulative housing, a plurality of contacts received in the housing and arranged along a longitudinal direction of the housing and a shielding member covering on the insulative housing for preventing EMI (Electro Magnetic Interference). The housing is provided with a base portion, a mating room surrounding by four side walls extending upwardly from a bottom wall and a tongue portion protruding into the mating room from the bottom wall. The tongue portion defines a plurality of passageways extending downwardly through the bottom wall to receive the contacts.
With development of electronics technology, the distance between two adjacent contacts is required to be smaller and smaller in accordance to decreasing length of the electrical connector or increasing contact number of the electrical connector. That is to say, the rib walls partitioning two adjacent contacts become thinner. So the contacts would interfere with each other when the rib wall breaks under frequent connection and disconnection. The rib walls would also have some disadvantages, such as distortion, crack in molding of the passageways.
Therefore, an improved electrical connector is desired to overcome the disadvantages of the related arts.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an electrical connector having a retaining spacer to retain retaining portions of terminals.
In order to achieve above-mentioned object, an electrical connector in accordance with a preferred embodiment of the present invention includes an insulating housing including a retaining spacers embedded therein and a plurality of terminals. The insulating housing has a base portion with a concaving room and an engaging portion. The terminal defines a retaining portion retained in the base portion, a contacting portion projecting in the engaging portion and a leg portion. The retaining spacer is received in the concaving room and press against the retaining portions of the terminals.
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.

DETAILED DESCRIPTION OF THE INVENTION
Reference will now be made to the drawing figures to describe the preferred embodiment of the present invention in detail.
Referring to FIGS. 1 and 2, an electrical connector in accordance with the present invention includes an insulative housing 1a including a pair of retaining spacers 1b embedded therein, a plurality of terminals 2 retained in the insulative housing, a metallic shell 3 shielding the insulative housing.
Referring to FIG. 2, the insulative housing 1a is provided with a longitudinal base portion 11 and an engaging portion 12 upwardly extending from the base portion in a vertical direction perpendicular to a longitudinal direction of the housing. The engaging portion 12 has a pair of longitudinal side walls 121, a pair of end walls 122 integrally connecting with the side walls and a tongue portion 123 parallel to said two side walls, thereby forming a receiving space 10 for receiving a mating element. A plurality of grooves 113 extend upwards from a bottom of the base portion to the tongue portion 123. Combination with FIG. 5, the terminal 2 includes a long retaining portion 21 retained in the grooves of the base portion, an arc contacting portion 22 upwards extending into the receiving space 10 along the tongue portion and soldering portion 23 downwardly extending. The grooves 113 has widen dimension in a traverse direction perpendicular to the tongue portion so as to allow the arc contacting portion to be inserted along the vertical direction.
The base portion 11 includes two concaving rooms 110, a middle portion 111 between the two concaving rooms and a pair of end portions 112 along the longitudinal direction at each side thereof. The middle portion 111 corresponds to the terminals 2. The grooves 113 extend to the middle portion and open to the concaving rooms 110, i.e. part of the retaining portions of the terminals expose to the concaving rooms 110.
Referring to FIG. 2, the end portions 112 include a pair of openings 1120 opening to the concaving room 110 and outward and a pair of slits 1121 extending downwards from the opening 1120. Combination with FIGS. 3, 4 and 6, the pair of retaining spacers 1b is cuboid-shaped and inserted into the concaving rooms 110 along the traverse direction. The retaining spacer 1b has a pair of protruding portions 1b1 at opposite ends thereof, which are inserted into the openings 1120 for preventing the retaining spacers from detaching from the insulative housing downwardly. The retaining spacer 1b includes a pair of rib portions 1b5 at opposite ends thereof and below the protruding portion, which is received in and locked with the slits 1121 for preventing the retaining spacers from being detached from the end portion along the traverse direction. The retaining spacer further defines a plurality of positioning posts 1b4 at inner faces thereof, which are received and interfered with corresponding holes 1110 on the middle portion for improving retaining force between of the retaining spacers and the insulative housing.
Referring to FIGS. 3, 5 and 6, the retaining spacers 1b have a plurality of ribs 1b3 pressing against the retaining portion 21 of the terminals in the grooves for preventing the terminals from traverse movement. The retaining spacer includes a top surface 1b6 abutting against the roof face of the concaving room 110. The ribs of the retaining spacers are wedge-shaped.
The metallic shell 3 cover an outside of the base portion and the retaining spacers 1b. The shell defines a plurality of retaining tails 31 inserted into the retaining spacers and a plurality of soldering legs 32 for electrical connecting with grounding trace of a PCB (not shown).
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 board general meaning of the terms in which the appended claims are expressed.
