[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a receptacle connector, and more particularly to a receptacle connector of a central processing unit having a protection member made of a metal material.

[0002]

[Prior art]

 A conventional receptacle connector for connecting a central processing unit (CPU) chip to a motherboard usually includes a base, a cover, terminals, a driving member, and the like. The base accommodates a plurality of terminals penetrating the upper and lower surfaces. The cover covers the upper surface of the base and can slide appropriately with respect to the base, and the cover has a plurality of through holes at positions corresponding to the terminal holes of the base. When the chip is mounted, the pins can be penetrated, further extended into the terminal holes, and brought into contact with the terminals with good timing. A cam or a driving member based on a driving action based on the eccentric wheel principle is conventionally housed in appropriate positions of the cover and the base, and is configured to interlock the cover and the base. Referring to FIG. 1, the driving member 9 drives the cover 8 by appropriate rotation with the aid of a tool (for example, an in-line driver) to change a relative position with respect to a base (not shown). be able to. In this process, the chip pins (not shown) attached to the cover 8 are accommodated in the first terminal holes (not shown) and are not brought into contact with the terminals (not shown). As soon as it slides in the direction and comes into contact with it and becomes conductive, an assembling effect such as zero insertion force (Zero Insertion Force, ZIF) can be achieved. A convex block 91 is horizontally extended at the top end of the driving member 9, and the cover 8 is provided with an arc-shaped groove 81 corresponding to the movement trajectory of the convex block 91 and prevents the driving member 9 from over-rotating. For this purpose, a stop wall 82 is provided at the extreme position of both rotations of the convex block 91.

[0003]

[Problems to be solved by the invention]

 However, the drive member 9 of the receptacle connector is generally provided with a sufficient strength by using a metal material by direct contact with an auxiliary tool (for example, an in-line driver or the like). Usually, since a plastic material is used, the position of the stop wall 82 of the arc-shaped groove 81 is clearly insufficient in strength, and is easily worn because the convex block 91 of the driving member 9 frequently contacts. . In addition, if the operator applies too much force when rotating the driver, the convex block 91 applies a maximum collision force to the stop wall 82, destroying the initial structure and causing a gap in the deformation. Thus, the stop wall 82 cannot provide a good control action for the proper rotation of the driving member 9 and may affect the stable transfer of the electric signal. The drive member 9 uses an eccentric ring structure, and the plastic cover 8 and the base are worn and easily deformed in contact with the drive member 9 due to long-term use. The function cannot be achieved.

An object of the present invention is to provide a type of receptacle connector, which is provided with a protective member made of a metal material, so that a cover and a base of the receptacle connector can provide a good protective action to a plastic portion close to a driving member, thereby reducing wear. By improving the structural strength of the portion, it is possible to avoid the destruction of the function of the drive member due to over-rotation, and thus it is possible to realize a more stable electric signal transfer effect.

The spacer 51 and the gasket 52 are formed in a substantially T-shape. In addition, both are made of a metal material. 4, the spacer 51 is fitted to the cover 20 by an insert molding method, has a sheet-shaped main body 511, and has an elongated slot 512 at a central position of the main body 511. A pair of arc-shaped walls 513 which are further extended in both directions from the center of the slot 512 to form a pair of arc-shaped walls 513 are provided so that a circular through-hole 514 communicating the slot 512 to the center of the slot 512 is formed. It is formed. A pair of stoppers 515 is installed on one side wall of the slot 512 so as to extend upward on both sides of the arc-shaped wall 513, and the stopper 515 extends into the base hole 25 of the cover 20 and abuts against the stop wall 251. You. A pair of small circular holes 516 are also provided at positions adjacent to both end edges of the spacer 51. When the spacer 51 and the cover 20 are insert-molded in the mold cavity, plastic is accommodated. The spacer 51 is fixed to the lower surface of the cover 20. The gasket 52 is fitted into the concave tank 14 corresponding to the base 10, and a substantially rectangular through hole 521 is provided at the center.

The driving device 40 includes a first column 41, a second column 42, and a third column which are integrally connected from an upper direction to a lower direction, and each have a cylindrical shape whose diameter gradually decreases. The body 43 and the fourth pillar 44 are included. A convex block 45 is provided on the side wall of the first column 41 so as to extend outward. The first column 41, the second column 42, the third column 43, and the fourth column 44 are respectively formed by the cover hole 25 of the cover 20, the through hole 514 of the spacer 51, the through hole 521 of the gasket 52, and the base 10. The semi-circular hole, the through hole 514, and the base hole 15 in the cover hole 25 are substantially the same diameter as the first, second, and fourth pillars 41, 42, and 44, and are accommodated in the base hole 15. It is installed so as to match the gap. The column is rotatable in a corresponding hole. The short side of the through hole 521 of the gasket 52 is substantially equal to the diameter of the third column 43, but the long side is formed larger than the diameter of the third column 43, so that the through hole 521 has the inside of the third column 43. And is slidably stored on the long side. The convex block 45 rotates in the semicircular hole having a large diameter of the cover hole 25 along the hole wall, and its movement trajectory is limited to the stop wall 251. Further, the first and second pillars 41 and 42 are installed coaxially, the third and fourth pillars 43 and 44 are also installed coaxially, and the two axes are shifted by a certain distance. Due to the structural design of the eccentric ring, the drive member 40 moves the cover 20 in parallel with the base 10 via an external tool (for example, an inline driver), and moves the cover 20 between the first and second positions. In the first position, the chip conductive portion and the conductive terminal 30 are separated from each other, and when in the second position, the chip conductive portion and the conductive terminal 30 are electrically connected.
