Abstract

An electrical connector is used for electrically connecting a wafer module to a printed circuit board and comprises a base, a cover board and a locking part; the cover board is assembled on the base and can move correspondingly to the base up and down; and the locking part is pivotally connected onto the base by a first pivot and used for locking the wafer module onto the base. The locking part is provided with a fixing holding part, and a locking part which extends forwards from the fixing holding part, wherein, the fixing holding part is provided with a long and narrow through hole which is internally accepted with a second pivot that can cause the locking part to be pivotally connected onto the cover board. The second pivot can move up and down in the through hole under the drive of the cover board and simultaneously drives the locking part to rotate so as to open or close the locking part. The electrical connector does not need to set a torsion spring to provide rotating force, thus not only simplifying the structure of the electrical connectors, but also being capable of providing stable electrical connection.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, especially a kind of electric connector that makes things convenient for wafer module Performance Detection.

[background technology]

In the Electronic Packaging circuit that constitutes by some actives and passive component, for example (,) the wafer module, be the miniaturized electric sub-component, in use safe and reliable in order to guarantee it, nearly all wafer module must be tested before installation.The wafer module is carried out long high temperature running, the wafer module that has defective was lost efficacy as early as possible, eliminate thereby defective wafer module screened, and the wafer module by test just can be used safely after being assembled to electronic terminal product, can not lose efficacy as early as possible.

Figure 1 shows that Chinese utility model patent announces the relevant electric connector 1 ' of a kind of and the utility model that is disclosed for No. 201029122, it comprises matrix 2 ', be positioned at the sliding panel 3 ' on the matrix 2 ', the top board 4 ' of fixedlying connected with sliding panel 3 ', be contained in the plurality of conductive terminals (not shown) in matrix 2 ' and the sliding panel 3 ', two pressing plates 6 ' that are connected with matrix 2 ' and can move up and down with respect to matrix 2 ', elasticity is articulated in the locking part 5 ' of matrix 2 ' both sides, and place the fixture of matrix 2 ' bottom, described fixture to comprise fixed head 8 ' and place base plate 7 ' on the fixed head 8 '.

Pressing plate 6 ' is a tabular, and it is provided with the first surface 63 ' of carrying operating physical force, and and first surface 63 ' opposing second surface 64 ', protrude the press section 65 ' that extension is provided with a pair of effect locking part 5 ' in the middle part of second surface 64 '.

Locking part 5 ' is installed in the groove 23 ' of matrix 2 ', and it comprises holding parts 51 ' and holding parts 51 ' the upwardly extending locking part 52 '.Described holding parts 51 ' convexes with rotating shaft 511 ' and can be fixed in the groove 23 ' of matrix 2 '.Locking part 5 ' below also need be provided with torsion spring (not shown) in order to the rotatory force of locking part 5 ' closure to be provided.Holding parts 51 ' drives for pressing plate 6 ' towards having the pressure-bearing portion 512 ' with inclined-plane.

During assembling, top board 4 ' and sliding panel 3 ' are fixed, then sliding panel 3 ' and top board 4 ' are fixed on the upper surface of matrix 2 ', conducting terminal (not shown) is housed in matrix 2 ' and the sliding panel 3 ', then fixture is fixed on matrix 2 ' bottom after locking part 5 ' is fixed in the relative both sides of matrix 2 ', at last pressing plate 6 ' is fixed on the matrix 2 ', pressing plate 6 ' and locking part 5 ' are positioned at the same side of matrix 2 '.When the first surface 63 ' of pressing plate 6 ' was subjected to operating physical force, pressing plate 6 ' moved downward, and press section 65 ' presses in the pressure-bearing portion 512 ' of locking part 5 ', and locking part 5 ' is provided motion; When operating physical force was cancelled, pressing plate 6 ' returned original position under the effect of torsion spring (not shown), locking part 5 ' the reverse former pivot direction of rotation motion.

But, when pressing plate 6 ' forces in locking part 5 ', can produce an opposing elastic force because torsion spring (not shown) is compressed, so the operating physical force that need be bigger and the travel path of wayward locking part 5 '; In addition, because being provided with of torsion spring (not shown) need take rotating shaft 511 ' below certain space, do not satisfy electric connector miniaturization development trend.

In view of above-mentioned drawback, be necessary to provide a kind of improved electric connector in fact, to overcome the defective of above-mentioned electric connector.

[utility model content]

The technical problems to be solved in the utility model provides a kind of simple in structure and the stable electric connector that electrically connects can be provided.
