Abstract
Description
- 1. Field of the Invention
- The present invention relates to a socket connector for electrically connecting a central process unit (CPU) to a printed circuit board (PCB).
- 2. Description of Related Art
- Socket connectors for mounting CPUs on a PCB are well known. The socket connector may be mounted to the PCB, while the CPU is snap-fitted into the socket connector. One advantage of this arrangement is that, unlike CPUs that are soldered directly on the PCB, a CPU that is mounted in a socket connector can be easily disconnected from the PCB for testing and replacement. However, the relatively dense layout and small size of electrical contacts on some CPUs necessitates precise alignment both between the socket connector and the PCB, and between the CPU and the socket connector.
- In general, a socket connector includes an insulative housing and a plurality of electrical contacts received in the insulative housing. For example, U.S. Pat. Nos. 6,196,849 and 6,786,738 disclose such a socket connector comprising a housing defining an array of holes therethrough corresponding to an array of contacts of the CPU, and a plurality of electrical contacts received in the holes. The housing that is molded from an insulative material is of a single-piece structure. However, as the housing is a thin, flat plate, after it is molded, during the cooling course, it will be warped. Thus the holes in the housing will be shoved or skewed. As a result, the electrical contacts cannot be placed in the holes correctly. Or even through the electrical contacts are placed into the holes, precise alignment between the CPU and the socket connector cannot be ensured. That causes electrical connection between the CPU and the PCB to become unreliable.
- Thereby, an improved socket connector is required to overcome the disadvantages of the prior art.
- An object of the present invention is to provide a socket connector which has reliable structure and can perform securely electrical connection between a central process unit (CPU) and a printed circuit board (PCB).
- In order to achieve above-mentioned objects, a socket connector in accordance with a preferred embodiment of the present invention includes a housing, and a number of electrical contacts received in the housing. The housing, being of a frame defining an opening, is constructed by joining pieces of separate housing-plates end by end. Each housing-plate defines a number of channels therethrough. The electrical contacts are respectively received in the channels, and each has a contact beam projecting out to electrically connect with the CPU.
- Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
-
FIG. 1 is a simplified, exploded, perspective view of a socket connector in accordance with the preferred embodiment of the present invention; -
FIG. 2 is an inverted perspective view ofFIG. 1 , but springs and electrical contacts are removed; -
FIG. 3 is a partly assembled view showing housing-plates ofFIG. 1 assembled to form a housing; -
FIG. 4 is view showing the socket connector ofFIG. 1 after assembled, and a pick up cap to be assembled to the socket connector; and -
FIG. 5 is an assembled view ofFIG. 4 , showing the pick up cap being assembled on the socket connector. - Reference will now be made to the drawing figures to describe the present invention in detail.
- Referring to
FIG. 1 , asocket connector 100 in accordance with the preferred embodiment of the present invention comprises ahousing 1, a plurality ofelectrical contacts 2 to be received in thehousing 1, acover 3 for closing theelectrical contacts 2, andsprings 4 for linking thecover 3 and thehousing 1. - The
housing 1 comprises four pieces of separate housing-plates plate housing 1 can be controlled more easily. As the four housing-plates plate 1 c to be typical of all the housing-plates first end 11, asecond end 12, and amiddle portion 10. The twoends middle portion 10,wherein thefirst end 11 has an under surface upper than that of themiddle portion 10 and thesecond end 12 has an upper surface lower than that of themiddle portion 10. Thefirst end 11 defines abinding hole 112 and afirst aligning hole 111. Thesecond end 12 has abinding tab 122 and asecond aligning hole 121. - Referring to
FIGS. 1 and 3 , the four pieces of housing-plates plate 1 a with other two housing-plates will be described as an example. The housing-plates first end 11 a of the housing-plate 1 a is overlapped onto thesecond end 12 b of the housing-plate 1 b, together to make up a thickness proximate to that of themiddle portion 10, while the first aligninghole 111 a aligning with second aligninghole 121 b to form aunitary hole 14, and thebinding tab 122 b being received in thebinding hole 112 a to bind the twoplates binding tab 122 b has a diameter slightly larger than that of thebinding hole 112 a, the twoplate binding tab 122 b is forced into thebinding hole 112 a. Alike, the housing-plates second end 12 a of the housing-plate 1 a is overlapped to the first end 12 d of the housing-plate 1 d with thesecond aligning hole 121 a aligning with the first aligninghole 111 d and thebinding tab 122 a received within thebinding hole 112 d. - The
middle portion 10 of each housing-plate defines a plurality of channels 105 (only partially shown) therethrough for receiving theelectrical contacts 2. Eachelectrical contact 2 has acontact beam 21 to project out of thehousing 1 to electrically connect with a central process unit (CPU) (not shown), as shown inFIG. 3 . - At the
middle portion 10 adjacent to the twoends rim 104 protruding from outer edges thereof, a pair ofspring receiving holes 102 for accommodating one ends of thesprings 4, and arecess 103 between the spring receivingholes 102. Additionally, anear 101 projects outwardly from a longitudinal middle of themiddle portion 10. Theear 101 defines a slot therethrough. Corresponding to the four pieces of housing-plates cover 3 comprises four pieces of cover-plates FIG. 2 , each cover-plate has a pair ofmiddle legs 32 and a pair ofend legs 33 at each end thereof to be respectively inserted into the slot of theear 101 and recess 103 in housing-plate, and defines secondspring receiving holes 34 for accommodating the other ends of thesprings 4. Then the cover-plates are assembled to corresponding housing-plate to cover themiddle portion 10. - The assembled view of the
socket connector 100 is shown inFIG. 4 . The cover-plates are enabled to float up and down relative to the housing-plates via thesprings 4 and define a plurality ofparallel slots 31 therethrough for the contact beams 21 (shown inFIG. 3 ) to pass through while the cover-plates floating down. Theslots 31 are defined along a breadth direction perpendicular to the longitudinal direction of corresponding housing-plate, eachslot 31 corresponding to an array ofcontact beams 21 along the breadth direction. Thus, when the CPU is assembled on thesocket connector 100, thecover 3 is pressed to float down and thecontact beams 21 project out of thecover 3 through theslot 31 to electrically connect the CPU, wherein the CPU is restricted in a flange formed by therims 104 against unexpected displacement. But before thesocket connector 100 is loaded, for example, during carrying or transmitting of thesocket connector 100, thecover 3 is supported by thesprings 4 in a position closing thecontact beams 21 to prevent them from accidental damage. - Moreover,
FIG. 4 shows a pick upcap 5 to be assembled to thesocket connector 100. The pick upcap 5 comprises aflat plate 51 defining a circle of throughholes 52 therein, and fourretention posts 53 respectively extending down from four corners of theflat plate 51 to be received in theunitary hole 14 of thehousing 1 to retain the pick upcap 5 to thesocket connector 100.FIG. 5 shows the pick upcap 5 being assembled to thesocket connector 100. During transmitting of thesocket connector 100, the pick up cap can be catch up by a cupula. Thus, in virtue of the pick upcap 5, thesocket connector 100 can be picked up conveniently. - The disclosure is illustrative only, changes may made in detail, especially in matter of shape, size, and arrangement of parts within the principles of the invention.
