1. Field of the Invention
The present invention relates to an electrical connector, and more particularly, to an electrical connector having seating members arranged between contacts thereof for testing the positions of the contacts.
2. Description of the Prior Art
Taiwanese Utility Model Patent No. M244598 issued to Lu on Sep. 21, 2004 discloses a conventional electrical connector for electrically connecting a module with a PCB. The electrical connector comprises a socket body having a number of terminals received therein and a metallic cover assembled to the socket body. The socket body comprises a base and two sidewalls extending upwardly from the base. The base and the sidewalls form a space for disposing a module therein. The base defines a plurality of passageways for receiving the terminals therein. The terminal comprises a contacting portion extending into the space for electrically connecting with the module. The cover defines a slot and the side surface of the side wall defines a pinshaft received in the slot and can move into the slot.
When the insulative housing is formed through the molding process, the base of the insulative housing forms a large surface which is easy deformed during molding. Generally, the base serves as a datum for testing the positions of the contacts. Therefore, it is difficult to test true position of the contacting portion of the terminals due to deformation of the base. Accordingly, manufacture precision of the electrical connector is increased.
In view of the above, a new electrical connector assembly that overcomes the above-mentioned disadvantages is desired.
Accordingly, an object of the present invention is to provide an electrical connector having seating members arranged between contacts thereof for testing true position of the contacting portions of the contacts.
To fulfill the above-mentioned object, an electrical connector comprises an insulative housing, a plurality of contacts and a cover, the insulative housing comprises a plurality of sidewalls extending upwardly from the base, the base and the sidewalls together form a receiving space, the base defines a plurality of passageways and a seating member located between every two passageways, the contacts are received in the passageways and each defines a contacting portion extending into the receiving space, the contacting portion extends beyond the upper surface of the seating members, the cover is pivotally assembled on two opposite sidewalls of the insulative housing and is located between a closed position, in which the receiving space is closed and an opened position, in which the receiving space is accessible.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawings to describe the present invention in detail.
Referring to
The insulative housing 1 is configured to a rectangular shape and comprises a base 10, four sidewalls 12 extending upwardly from the base 10. The base 10 and the four sidewalls 12 together formed a receiving space 101. The base 10 defines a plurality of passageways 102 arranged in a first row and a second row. The base 12 also defines a plurality of seating members 1031 adjacent the passageways 102. The seating member 1031 is arranged between two adjacent passageways 102 in the first row and the second row, and the seating member 1031 in the first row or the second row is corresponding to the passageway 102 in the second row or the first row. One of the sidewalls 12 defines an opening 15 communicating with the receiving space 101. Two of the sidewalls 12 are opposite to each other and each defines a groove 1223 at one end, a recess 1222 at the other end and a lock portion 1221 near the recess 1222.
The contacts 2 are positioned in the passageways 102 and each comprises a base portion 22, a soldering portion 23 extending from one end of the base portion 22 and a spring arm 21 extending from the other end of the base portion 22. The spring arm 21 defines a contacting portion 211 extending into the receiving space and the contacting portion 211 is located beyond the upper surface of the seating member 1031. The contacts 2 in the first and second rows are opposite to each other.
The cover 3 is made of sheet metal and comprises a flat body plate 31 and two flanges 32 extending downwardly from the body plate 31. The flange 32 defines a column-shaped pinshaft 322 corresponding to the groove 1223 and also defines a stop portion 321 corresponding to the lock portion 1221. The stop portion 321 comprises a connecting portion 3210 extending downwardly from the flange 32 and an interlock portion 3211 extending curvedly from the connecting portion 3210. The interlock portion 3211 defines a guiding portion 3212 at an end thereof
When the electrical connector 100 is assembled, the contacts 2 are assembled in the passageways 102 and the cover 3 is assembled on the insulative housing 1. The pinshaft 34 is located in the groove 1223, so that the cover 3 can move from an opened position to a closed position.
Referring to
The insulative housing 1 is provided with a plurality of seating members 1031 on the base 12 thereof Therefore, it is the seating members 1031 not the base 12 servers as a datum for testing the contacts 2. Since the seating member 1031 has a smaller area than the base 12, deformation during molding will not affect the seating member 1031 as the base 12. Therefore, the seating member 1031 can be a more acurate datum than the base 12. Accordingly, it is easily and reliably to control the positions of the contacts 2.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
