Abstract
The utility model provides a printer interface seat, including rectangular base, the preceding side of base is provided with prints parallel port data connector, and the side is provided with data welding pin above the base, prints parallel port data connector and is connected with data welding pin electricity, and the left and right sides of base is provided with circular through -hole, to the side of the axis perpendicular to base of circular through -hole above -mentioned, is provided with the fixed pin of metal in the circular through -hole, fixed pin is greater than the cylindrical of upper portion for the lower part diameter, and it is protruding to be provided with the annular in the circular through -hole, and fixed pin is provided with the holding from top to bottom respectively the bellied ring channel of annular. The utility model discloses can break away from a fixed pin with PCB earlier, break away from another fixed pin again, take an electric iron to melt data welding pin at last and can take off the combination hub, convenient operation.
Description
Technical field
The utility model relates to parallel ports of printer socket field, particularly relates to a kind of printer interface seat.
Background technology
Existing parallel ports of printer combination hub is fixed on pcb board more firmly in order to allow combination hub, and all can there be fixing pin at combination hub two ends, is welded together, combination hub can be avoided to rock on pcb board by these two fixing pins and pcb board.When combination hub damage will be replaced, there are two kinds of ways.A kind of be melt tin on the tin of two fixing pins and the connection pin of the combination hub tin of three parts (total be) simultaneously, then take down combination hub from pcb board, one is also had to be use solder sucker, tin on the connection pin of the tin on fixing pin and combination hub is melted and extinction, then just can take off combination hub.The speed of a kind of front method, but the tin on pin will be melted simultaneously, and people is difficult to the tin simultaneously melted on pin, needs multiple people to coordinate.Rear a kind of method speed is very slow, because the tin on pin and PCB will be separated completely, consuming time very long.In a word, take off combination hub from PCB relatively to bother.
Summary of the invention
The technical problems to be solved in the utility model, is to provide a kind of printer interface seat, solves and takes off the relatively troublesome problem of combination hub from PCB.
The utility model is achieved in that a kind of printer interface seat, comprise rectangular pedestal, before pedestal, side is provided with and prints parallel port data connector, the side above of pedestal is provided with data welding pin, print parallel port data connector to be electrically connected with data welding pin, the left and right sides of pedestal is provided with manhole, axes normal side above pedestal of manhole, the fixing pin of metal is provided with in manhole, described fixing pin is that lower diameter is greater than the cylindrical of top, annular protrusion is provided with in manhole, fixing pin is respectively arranged with the cannelure of accommodating described annular protrusion up and down.
The utility model tool has the following advantages: first a fixing pin and PCB can be departed from, then depart from another fixing pin, finally takes an electric iron to melt data welding pin and can take off combination hub, handled easily.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model cross-sectional view.
Embodiment
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with execution mode.
Refer to Fig. 1 and Fig. 2, the utility model provides a kind of printer interface seat, comprise rectangular pedestal 1, before pedestal, side is provided with and prints parallel port data connector 2, the side above of pedestal is provided with data welding pin 3, print parallel port data connector to be electrically connected with data welding pin, the left and right sides of pedestal is provided with manhole 4, the axis (i.e. the trend of manhole or the direction of manhole longest edge) of manhole, perpendicular to the side above of pedestal, is provided with the fixing pin 5 of metal in manhole.Fixing pin can move up and down in manhole, and described fixing pin is that lower diameter is greater than the cylindrical of top, is provided with annular protrusion 6 in manhole, and fixing pin is respectively arranged with the cannelure 7 of accommodating described annular protrusion up and down.
The utility model is when welding, up shift two fixing pins onto the end, now annular protrusion can be placed in the cannelure below fixing pin, blocks fixing pin and makes it to move easily, and the big column simultaneously fixing pin bottom also can withstand on manhole.Then combination hub is placed on PCB and welds, pedestal firmly can be fixed on PCB.When needs take off combination hub, first, after taking electric iron to be melted by the tin on a fixing pin, fixing pin is twitched downwards, this fixing pin and PCB are departed from, now annular protrusion can be placed in the upper annular groove of fixing pin, avoids fixing pin and combination hub to depart from.Then pin is fixed to another one and carry out identical operation, make another one fix pin and PCB departs from.Finally, use electric iron in data welding pin, be paved with tin and melt, because data welding pin close together, pin is less, and an electric iron can melt the tin of this area simultaneously, can take out combination hub after thawing.Need not draw tin like this, speed is fast, and without the need to melting fixing pin and data welding pin simultaneously, a people can complete, handled easily.
The foregoing is only embodiment of the present utility model; not thereby scope of patent protection of the present utility model is limited; every utilize the utility model specification and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
