Description

The module type electric connector

The utility model is about a kind of module type electric connector, but refers in particular to a kind of strong fix and cover the module type electric connector of electric connector terminal welding ends.

In the computer industry, under the trend of computer miniaturization and multifunction, various types of electric connectors have been produced, such as jammed edge electric connector, D type electric connector etc.But, longer when the terminal leg that electric connector is required, if directly with the in addition accurately bending of electric connector terminal leg, and make it place on the substrate that this connector assembly fixes not a duck soup.Especially in order to save the space, computermaker is arranged according to vertical direction and is stacked two groups of electric connectors, producing tight effect, but it has increased the vertical range between upper electric connector and substrate, has also increased the uncertainty of this upper electric connector terminal leg physical location simultaneously.Because no any positioner can help to align the electric connector terminal leg, the situation that the electric connector terminal leg is easily departed from so may cause the loss ratio of electric connector terminal when the assembling welding to increase, and causes its cost to increase.Based on above-mentioned deficiency,, generally all include positioner, to align bonder terminal leg or upper electric connector terminal leg for most of electric connector terminal leg long electric connector or stack-type electric connector.

In some jammed edge electric connectors, but contain positioner strong fix terminal leg to the substrate in the corresponding through hole.Yet this existing positioner mostly is tabular, also has to adopt stair-stepping plate locator the positioner that is disclosed for No. 81202795 and No. 85215015 as the Taiwan patent application.

See also Fig. 1 and Fig. 2, it is the socket 10 of the bayonet connector that disclosed for No. 85215015 of above-mentioned Taiwan patent application, it mainly is made of a socket main body 12 and a terminal position plate 14, this socket main body 12, can plug therebetween vertical embedding slot 16 for wafer set except being provided with one, the terminal that also is provided with the plurality of parallel that is communicated with the embedding slot 16 sets firmly groove 18, and terminal 20 is installed in this kind terminal respectively and sets firmly in the groove 18.In addition, this socket main body 12 is respectively equipped with a chimeric post 22 in relative these embedding slot 16 terminal 20 overhanging side two ends, by this two chimeric post 22 so that the function that sets firmly at these terminal position plate 14 two ends to be provided, and this terminal position plate 14 vertically is installed in a lateral margin 24 places of the overhanging side of these socket main body 12 set terminals, 14 of this terminal position plates are provided with the through hole 26 corresponding to this terminal 20 in addition, by these socket main body 12 outward extending terminal 20 inserted terminals after 90 degree turnovers, can pass the set corresponding through hole 26 of terminal position plate 14 respectively, and then utilize terminal 20 ends stretch out terminal location-plate 14 to be installed in a circuit board (figure does not show) and go up in the corresponding through hole, thereby make 12 one-tenth levels of this socket main body be installed in structure on this circuit board.

But, though but this positioner strong fix terminal leg reaches the purpose that aligns.Yet the inserted terminal of this positioner and electric connector chien shih terminal is exposed to the space to a great extent, is short-circuited for touching very easily of foreign object.To carry on the terminal position plate for another the fruit desire, when reducing electric connector and being installed on the circuit board height, then this positioner does not just have the space can be for fixing.Moreover, this positioning device structure and corresponding socket main body need have the connected structure design of operability, to fix this positioner on the tram, therefore, generally the body in electric connector must comprise rear portion (as above-mentioned chimeric post a 22) positioner combination therewith of extending, cause mould to become complicated, and cost raise.

The purpose of this utility model is to provide a kind of module type electric connector, and this module type electric connector is with low cost, and the effect of tool clad terminal and assist location terminal leg.

Another purpose of the present utility model is to provide a kind of module type electric connector, this module type electric connector is provided with the location lid, it can be avoided because of foreign object is short-circuited to touching of terminal leg, and because of being installed on the problem that the height on the circuit board makes location-plate not have the space confession to fix with carrying the reduction electric connector on the terminal position plate.

The technical solution of the utility model is: it mainly comprises electric connector socket main body, plurality of terminals and terminal position lid.Wherein this terminal position lid is abutted against mutually with socket main body, and the end that this terminal position lid is abutted against socket main body is provided with abutment surfaces, and this abutment surfaces is the back side relatively, and the top and bottom that connect between this abutment surfaces and the back side are respectively end face and plug surface.Be provided with some draw-in grooves in this location lid, these some draw-in grooves communicate with plug surface with abutment surfaces respectively, and also are provided with at least one pair of pit in draw-in groove connection inboard, plug surface place, in order to hold corresponding projection on the terminal welding ends.Cooperating between the draw-in groove inside recess of the projection by the plurality of terminals welding ends and this terminal position lid, can make this terminal position lid relative fixed in this socket main body.

The set location of this module type electric connector lid can be avoided because of foreign object is short-circuited to touching of terminal leg it, and because of being installed on the problem that the height on the circuit board makes location-plate not have the space confession to fix with carrying the reduction electric connector on the terminal position plate.
