Abstract

A connector comprises a plastic shell, a plurality of terminal seats which are arranged in the shell and a rear cover which seals one end of the shell, wherein two ends of the shell are respectively defined as an applying end and an inserting end, the inner part of the shell is provided with more than one containing chambers which communicate the applying end and the inserting end and is used to insert the terminal seats. The middle portion between the terminal seats and the perisporium of the shell is provided with a fastening portion for mutually fastening and a socket of the terminal seats, which causes the terminal seats to be fixed in the containing chamber. When being replaced, an out force from the outboard of the shell is applied to the terminal seats to make the fastening portion release from the socket of the terminal seats, thereby dissembling the terminal seats. The inserting end of the shell borrows the rear cover to insert card to seal, thereby having the advantages of quick arrangement and smooth external appearace.

Description

Connector

Technical field

The utility model relates to a kind of line connector, but relates in particular to a kind of Fast Installation, convenient for detaching and changing connector.

Background technology

Existing personal computer, mobile computer are equipped with the connecting interface that network is used, as Fig. 4, Figure 5 shows that a kind of common single-layer type connector, it comprises a plastics system shell 40, a metal case 50 and several terminals seat 60, wherein, shell 40 is a rectangle housing, wherein two relative edges are penetration state, and be defined as application end 41, insertion end 42 respectively in the both ends of the surface that run through, shell 40 inner one-body molded several space bars 43 in addition, the inner space is separated into several rooms 44, assemble a described terminal base 60 in each room 44 respectively.This terminal base 60 comprises that a base plate 61, is installed on the circuit board 62 on the base plate 61 and is welded in circuit board 62 and is positioned at the shell fragment group 63 of application end 41 1 ends, described circuit board 62 welding number branch connecting pins 64, and each pin 64 is to be piercing in base plate 61 bottoms.On the internal perisporium of two minor faces of shell 40 and each space bar 43, be respectively equipped with an outstanding fastening part 45, in the middle of terminal base 60 is inserted room, promptly by fastening part 45 blocks of both sides in circuit board.

Again, described metal case 50 is lamellar metal, so as to being covered in the outer circumferential side of shell 40, to prevent static, the two opposite sides of this metal case 50 are respectively equipped with an outstanding barb sheet 51, again in the top margin of metal case 50, be provided with the outstanding back catch 52 of a slice outwardly corresponding to insertion end 42 1 ends of shell 40, the both sides of this back catch 52 are respectively equipped with one and bore a hole 53.After metal case 50 covers were overlying on shell 40 surfaces, catch 52 down bent and hides in insertion end 42 after inciting somebody to action, and by the perforation 53 and barb sheet 51 mutual plug-in cards that are positioned at both sides.Yet this kind has the connector of metal case 50 still exists following shortcoming:

1. because shell is to establish with outstanding fastening part in internal perisporium, in circuit board one side, when needs change terminal base, have the inconvenient application of force, need special tool(s) to carry out the shortcoming that metal shell splits out with block.

2. bending back catch for convenience, therefore will the back catch with the top margin of metal case between only is connected with several braces, yet, when will back catch bending being covered in insertion end, can form the stress collected state, very easily fracture and deposited use at the brace place.

Existing connector is provided with the sheet metal that can eliminate static except aforementioned, other has a kind of is directly to establish an earth connection on circuit board, in encapsulating sealing dress mode earth connection and circuit board surface are encapsulated again, yet, because canned program need pass through encapsulating, oven dry supervisor, required time is longer, and the package surface out-of-flatness is not attractive in appearance, has the shortcoming that to separate after the terminal base encapsulation again.
