Abstract
The utility model provides a printer parallel port combination hub, 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, is provided with square groove about the base on the side, to the side of square groove's axis perpendicular to base above -mentioned, is provided with the fixed pin of metal in the square groove, fixed pin is " L " shape, is provided with the arch in the recess, and fixed pin is provided with the holding from top to bottom respectively bellied through -hole, recess upper portion both sides are provided with the lug, the lug is used for avoiding the fixed pin roll -off recess that makes progress. 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 parallel ports of printer combination hub.
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 parallel ports of printer combination hub, solves and takes off the relatively troublesome problem of combination hub from PCB.
The utility model is achieved in that a kind of parallel ports of printer combination hub, 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 side of pedestal is provided with square groove, axes normal side above pedestal of square groove, the fixing pin of metal is provided with in square groove, described fixing pin is " L " shape, projection is provided with in groove, fixing pin is respectively arranged with the through hole of accommodating described projection up and down, both sides, groove top are provided with projection, described projection is used for avoiding fixing pin upwards to skid off groove.
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 parallel ports of printer combination hub, 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 side of pedestal is provided with square groove 4, the axis (i.e. the trend of square groove or the direction of square groove longest edge) of square groove, perpendicular to the side above of pedestal, is provided with the fixing pin 5 of metal in square groove.Fixing pin can move up and down in a groove, described fixing pin is " L " shape, and be provided with protruding 6 in groove, fixing pin is respectively arranged with the through hole 7 of accommodating described projection up and down, both sides, groove top are provided with projection 8, and described projection is used for avoiding fixing pin upwards to skid off groove.
The utility model is when welding, two fixing pins are up shifted onto lateral part and the bump contact of fixing pin, now projection can be placed in through hole below fixing pin, blocks fixing pin and makes it to move easily, be then placed on PCB by combination hub and weld.Pedestal can be fixed on PCB by fixing like this pin, more firmly.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 the protruding through hole above that can be placed in 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.
