BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention generally relates to a connector assembly and more particularly to an electrical connector mounted on a printed circuit board.
2. The Related Art
The game industry is prospering with the development of computer technology in recent years, which expands the market of video game console manufacture greatly. The video game console demands good human-computer interactions. Recently, a new-fashioned product is developed to provide with more realistic and direct feelings. This kind of video game console transfers 300 million polygons (in which forms the game images are shown) per second, comparing with a rate of 66 million per second of traditional kinds.
The high-speed human-computer interaction is a good challenge to present data-transfer technology. One of the general countermeasure is to enhance the length of data the processor handles. The other is to enlarge the width of or append additional cables that transfer the data of the game to the processor, especially of those connectors that proved to be a bottle-neck.
However, in the conventional connectors, the feet portions of the conductive terminals are arranged in a matrix form. When the connectors are mounted to the printed circuit board, their feet portions match the board tightly and leave no space for those added cables to thread through between the connector and printed circuit board when needed.
SUMMARY OF THE INVENTION
In view of the foregoing, the present invention is proposed to provide a connector to conquer the disadvantage mentioned above. The present invention of connector comprises a dielectric housing and a plurality of conductive terminals. The dielectric housing has a plurality of terminal slots parallel to a top surface of the dielectric housing and a plurality of terminal pores corresponding to said terminal slots defined in the dielectric housing. Each of the conductive terminals has a vertical leg and a grasping portion bending from the vertical leg, the grasping portion forming a contact portion at a front end of the grasping portion. The terminal slots and the terminal pores are perpendicular to one another. The terminal pores are defined on both sides of a bottom surface of the dielectric housing. The grasping portions are inserted into the terminal slots. The vertical legs are inserted into the terminal pores and extended though a bottom surface of the dielectric housing. So a region is defined between two sides of the bottom surface of the dielectric housing.
As described above, between the vertical legs of the conductive terminals, an interspace is left for cables threading through when needed. In that case, the connector conquers the disadvantage of the present connectors.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Referring to FIGS. 1 and 2, a connector assembly 1 according to the present invention includes a dielectric housing 10 having an upper body 20 and a lower body 30, a plurality of conductive terminals 40 is retained in the dielectric housing 10, and a metal shelter 50 is engaged with the dielectric housing 10.
With reference to FIG. 3, an upper body 20 contains a tetrahedron base 21. A container space 22 is defined inside of the base 21, whose section is in an isosceles trapezoid shape. A tenon 23 is set in the container space 22 and extends to even out the front surface of the base 21. Two rows of terminal slots 24 are defined on the top and bottom surfaces in the body of the tenon 23. The terminal slots 24 on the top surface are superstratum slots 241 and on the bottom surface are underlayer slots 242. Each of the terminal slots 24 lies lengthways. At the front of the base 21 it extends out two inserting legs 25 downwards, each of which has dentations 251 on the body. And at its backside, two clamp legs 26 project downwards at both ends.
Referring to FIG. 4, a lower body 30 includes a rear wall 31. The rear wall 31 is divided into four steps and with their heights descending equally from back to front. On the top surface of each step, a plurality of terminal pores is defined drilling through the step to the bottom surface to receive the conductive terminals 40 therein. These terminal pores, naming first terminal pores 32, second terminal pores 33, third terminal pores 34, fourth terminal pores 35, are assembled at the both ends of each step, leaving the middle part aside with no terminal pores defined. At the backside of the rear wall 31, two flutes 36 are defined sunkening into each end to match the two clamp legs 26 of the upper body 20. The front part of the lower body 30 consists of two fixing bases 37 arranged at each end. A semicircular fixing hole 38 drills through to receive the inserting legs 25 of the upper body 20 in assembly.
Referring to FIGS. 5 and 6, the conductive terminals 40 consist of four rows of terminals. The conductive terminals from back to front are: first conductive terminals 41, second conductive terminals 42, third conductive terminals 43 and fourth conductive terminals 44.
As shown in FIG. 5, each conductive terminal 40 contains a vertical leg 45. The top part of each vertical leg 45 bends sidewards and forms a bending portion. The end of the bending portion makes a 90° turn and then extends flatly and forms a grasping portion 47. The end of the grasping portion 47 makes a V shape turn and forms an arm 48. A contact portion 49 is formed at the peak. In assembly, the grasping portion 47 and arms 48 of the four rows of conductive terminals 40 are received in the terminal slots 24. Meanwhile, the vertical legs 45 are set into two groups that bend sideward and received in the terminal pores (shown in FIGS. 7 and 8), leaving an interspace 451 between the two groups vertical legs 45.
As FIG. 6 shows, the grasping portions 47 of the first conductive terminals 41, second conductive terminals 42, third conductive terminals 43 and fourth conductive terminals 44 are descending evenly in length. The grasping portions 45 of the first conductive terminals 41 and the second conductive terminals 42 are at the same height. The grasping portions 45 of the third conductive terminals 43 and fourth conductive terminals 44 are at a lower height. The arms 48 of the first and the second conductive terminals 41,42 are just above those of the third and four conductive terminals 43, 44. The arms 48 of the first and the second conductive terminals 41,42 bend in a reverse V shape, at the same time the arms of the third conductive terminals 43 and the fourth conductive terminals 44 bend in a V shape. Their peaks form said contact portions 49.
Referring to FIG. 6 again, the conductive terminals 40 can be divided into two groups by their bending portions. The bending portions 46′ of left group terminals whose marked 46′ bended leftwards. The bending portions 46″ of right group terminals bend rightwards.
Referring to FIGS. 7 and 8, in assembly, each of the conductive terminals 40 is retained in the dielectric housing 10. Each of the terminal slots 24 contains each of the grasping portions 47 and each of the arms 48 of a conductive terminal 40. The contact portions 49 of the conductive terminals 40 protrude upwards from the superstratum slots 241 to contact with the interface components (not shown) of other devices; each of the terminal slots receives in a vertical leg 45 respectively. As the grasping portions 47 of the first conductive terminals 41 are longer than those of the second conductive terminals 42, their vertical legs 45 locate at the back of the second conductive terminals 42. The grasping portions 47 of the third conductive terminals 43 and the fourth conductive terminals 44 are received in the underlayer slots 242 of the tenon 24 in the same form. As the grasping portions 47 of the third conductive terminals 43 longer than those of the fourth conductive terminals 44, their vertical legs 45 are set in two lines. Since the grasping portions 47 of the second conductive terminals 42 are longer than those of the third conductive terminals 43, the vertical legs 45 of the conductive terminals 40 are divided into four rows.
FIGS. 6, 7 and 8 show how the conductive terminals 40 are arranged in the dielectric housing 10. In said form, the conductive terminals 40 are divided into four rows according to the lengths of their vertical legs 45 and grasping portions 48. Their bending portions 46′ bend leftwards and 46″ rightwards separately forming a reversing U shaped wide space in order to be contained into those terminal pores; that is, the vertical legs 45 of the first conductive terminals 41 are received in the first terminal pores 32. The vertical legs 45 of the second conductive terminals 42, the third conductive terminals 43 and the fourth conductive terminals 44 are received in the second terminal pores 33, the third terminal pores 34 and the fourth terminal pores 35 respectively.
As described above, when the connector is mounted on a PC board, an interspace 451 between the connector and PC board is formed by those vertical legs 45 of the conductive terminals 40. Hence, the added cables (not shown) then could thread through the interspace 451, and more spare space is saved for further design.
Although preferred embodiment of the present invention have been described in detail hereinabove, it should be clearly understand that many variations and/or modifications of the basic inventive concepts herein taught which may appear to those skilled in the present art will fall within the spirit and scope of the present invention, as defined in the appended claims.
