BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector, and more particularly to the electrical connector having a loading component to press an electronic package steadily mounted therein.
2. Description of Related Art
U.S. Pat. No. 7,658,633 issued to Terhune et al. on Oct. 22, 2008 discloses a socket adapted for electrically connecting an IC package and a PCB, comprising a body mounted on the PCB for electrically connecting the IC package, two bolts mounted on the PCB and beside the body and a clip for retaining the IC package in the body. The bolt has a header portion on the top with biggest size, a middle portion and a screw portion engaging with the PCB. The clip has two attaching portions, each defining a latch at a free end thereof, the clip links with the bolt by inserting the attaching portion toward the bolt to make the middle portion be received in the latch and the header portion is located upon the latch to prevent the attaching portion from upward movement.
As is well understood in the art, the trend of the printed circuit board becomes more and more smaller, so the bolt of the electrical connector mounted on the printed circuit board will not favor of miniaturization.
Therefore, an improved electrical connector is needed.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 and 3, an electrical connector used for electrical connecting an electronic package 6, comprises an insulative housing 2 with a plurality of contacts 3, a cover 4 mounted on the insulative housing 2 and a loading component 5 providing a downward force to the electronic package 6 in a vertical direction.
Referring to FIGS. 2 and 3, the insulative housing 2 is rectangular in shape and includes a base 21 with an array of contacts 3 disposed therein. The insulative housing 2 further includes two pair of opposite periphery sidewalls 22 combing with the base 21 to form a cavity 20 for receiving the electronic package 6. Recesses 220 are provided in one pair of the periphery sidewalls 22 and pass through the periphery sidewalls 22 to communicate with the cavity 20 to provide a receiving space for fingers of operator to handle. Another pair of periphery sidewalls 22 have engaging portions 230 each with a top engaging portion 2300 and a lower engaging portion 2301 in the vertical direction. The top engaging portion 2300 and the lower engaging portion 2301 forms a rib 2302 located therebetween. The rib 2302 defines a chamfer 2303 disposed upon thereof. Two adjacent periphery sidewalls 22 include anchoring blocks 240 to make the electronic package 6 exactly and steadily inserted into the cavity 20 of the insulative housing 2.
Referring to FIGS. 2 to 3, the cover 4 is made of metallic material and includes a main body 40 with a mating portion 400 that will be described in more detail hereinafter. The main body 40 has latches 41 extending downwardly from edges to engage with the engaging portion 230. Adjacent each latch 41 defines a gap 42 on the main body 40 used for increasing flexibility for the latch 41. Each latch 41 includes a contacting portion 410 extending downwardly from the main body 40 and a bent portion 411 extending downwardly from the contacting portion 410. The bent portion 411 includes a mating surface 4110 extending inwardly to engage with a bottom surface of the rib 2302 and an end portion 4111 extending outwardly for operation by operator. When the cover 4 assembled with the insulative housing 2, the bent portion 411 is lead by the chamfer 2303 into the lower engaging portion 2301 of the insulative housing 2 and the mating surface 4110 engaged with the bottom surface of the rib 2302 to hold the cover 4 to the insulative housing 2.
FIGS. 2-4 show the first embodiment of the loading component 5 with the corresponding mating portion 400. The loading component 5 has a flat cylinder in shape with a top surface 50, a bottom surface 51, and a cylindrical surface 52. The top surface 50 defines a groove 501 for a tool (not shown) to rotate the loading component 5 upwardly and downwardly in the vertical direction. The mating portion 400 includes a circular aperture 401 defined on a center of the main body 40. The aperture 401 edge defines internal screw thread 402 which is cooperated with external thread 520 defined on the cylindrical surface 52 of the loading component 5.
FIGS. 1 to 3 shows the loading component 5 assembled with the mating portion 400 of the cover 4. The loading component 5 is assembled into the aperture 401 of the mating portion 400 and the bottom surface 51 of the loading component 5 is used to urge a top side of the electronic package 6. The loading component 5 can exert a force to the electronic package 6 to adjust the loading component 5 near and far away respective to the cover 4 in the vertical direction.
FIGS. 5-6 show the second embodiment of the loading component 5′ with corresponding mating portion 400′. The mating portion 400′ is configured with a concave 404′ in bottom surface of the main body 40′. The concave 404′ is run through a top surface of the main body 40′ by an opening 403′ which is part defined on the top surface of the main body 40′ and part defined on sidewalls formed with the concave 404′. The loading component 5′ has a plate 50′ with a top surface 51′ and a bottom surface 52′. One end of the top surface 51′ has a block 53′ extending upwardly therefrom. The block 53′ defines a recess 530′ to allow operating by fingers of operator.
Referring to FIGS. 6-7, when the cover 4′ mounted to the housing 2 with the electronic package 6 assembled therebetween. The loading component 5′ is inserted into the concave 404′ from the opening 403′ till the block 53′ against the sidewalls of the opening 403′, and the bottom surface 52′ against the top side of the electronic package 6 to press the electronic package 6 electrically connected with the contacts (not shown in FIG. 6) in the housing 2.
In the present invention, the loading component 5,5′ can directly press the electronic package 6 and also directly connects with the mating portion 400,400′ of the cover 4, 4′ in the vertical direction so as to save the space of a printed circuit board (not shown) and has a small height in the vertical direction
Although the present invention has been described with reference to particular embodiments, it is not to be construed as being limited thereto. Various alterations and modifications can be made to the embodiments without in any way departing from the scope or spirit of the present invention as defined in the appended claims.
