Embodiment
Below in conjunction with accompanying drawing and preferred embodiment feature of the present utility model and technology contents are further specified.Accompanying drawing only is used to explain the utility model and is unrestricted.
The connector with function of shielding of Fig. 2, it is to come conducted signal by conducting resinl outside the garment bag of plug and the conducting resinl in socket, why adopts conducting resinl, is in order more to combine closelyr to save volume with garment bag.Yet its volume is still inadequately little, to such an extent as to be difficult to this conducting resinl shield technology is applied on the micro connector, even used, also makes the current drainage weak effect of micro connector owing to the contact resistance of conducting resinl is excessive.
In addition, adopt conducting resinl to also have other shortcomings, such as, when utilizing the conducting resinl conducted interference signal between plug and socket, its electric conductivity is poor.
For this reason, the utility model has been taked another kind of thinking, this thinking cardinal principle is, by elastic sheet metal is set outside plug, and at socket inwall relative set sheet metal, interference signal in the holding wire is guided to elastic sheet metal by shielding conductor, make its ground connection by sheet metal in the socket and shielding pin then, thereby reach the effect of shielding.Because the outer sheet metal of plug is flexible, therefore can guarantee to contact closelyr with sheet metal in the socket, shield effectiveness is also better, again because sheet thicknesses can be thinner for the conducting resinl of injection moulding, therefore can effectively control the volume of micro connector in addition.
As shown in Figure 3, be the structural representation of the plug of a kind of micro connector of the utility model, it generally comprises:
Further, shown in Fig. 4 a, 4b, 4c, structural representation for a kind of embodiment of the plug of a kind of micro connector of the utility model, here be that example describes only with the DIN formula plug that is used for Holter, EEGelectrode etc., shown in Fig. 4 c be its internal structure wherein, plug crust 36 is not shown among this figure.Among the figure; socket terminal 31, insulating barrier 32, elastic sheet metal 33, shielding conductor 35 and aforementioned schemes are similar; do not repeat them here; different is, also comprises plug crust 36 and compressed part 37, and wherein compressed part 37 has adopted copper band here; it has the effect that compresses shielding conductor and holding wire; tensile strength that can also the enhancing signal line, plug crust 36 is wrapped in the junction of plug and holding wire, plays a protective role.Here, holding wire is a coaxial line, by center conductor (also claiming heart yearn) and screen (such as aluminium foil, braiding copper mesh etc.) constitute, shielding conductor 35 in the utility model is to be connected with the center conductor of conducted signal, in the utility model, the screen in the coaxial line is used in combination with shielding conductor, so that interference signal is conducted to ground wire.
During concrete production, with the holding wire decortication, expose its screen earlier, then shielding conductor 35 is connected with this screen, at last shielding conductor 35 is guided to elastic sheet metal and get final product.Preferably, also screen can be twisted into one and become shielding conductor 35, can directly utilize the screen in the coaxial line like this.Preferably, elastic sheet metal 33 is the lantern shape, and it is a metal clips that outwards expands, and a fastening part 34 correspondingly can be set wale this metal clips, and copper band is adopted in present embodiment fastening part 34, and shielding conductor 35 is welded in the step place of this copper band.
The utility model also correspondingly provides a kind of socket of micro connector, shown in Fig. 5 a, 5b, 5c, is the structural representation of a kind of execution mode of socket, and wherein Fig. 5 a is that cutaway view is looked on the right side, and Fig. 5 b is a vertical view, and Fig. 5 c is a front view.This socket can comprise:
Optionally, sheet metal 44 differs and is decided to be the semicircle tubular shown in Fig. 5 a, 5b, the 5c, and it can also certainly, also can be not in other shapes shown in the accompanying drawing for complete cylindric.Preferably, sheet metal and cavity inner wall are close to, and cause conductive effect poor because of loosening in the time of can avoiding plug to insert like this.
As shown in Figure 6, be the structural representation of plug and socket provided by the utility model before and after combining, the structure of plug and socket and aforementioned similar does not repeat them here.When plug and socket in conjunction with the time, the sheet metal 44 in the elastic sheet metal 33 of lantern shape and the socket effectively contact, the holding wire pin 41 in the socket is inserted in the hole of the socket terminal on the plug, and the body of while socket terminal is held by the cavity of socket.Among the embodiment shown in the figure, the interference signal in the holding wire is passed through shielding conductor 35, (the fastening part 34) elastic sheet metal 33 in the plug successively, and the sheet metal in the socket 44, shielding pin 42, last ground connection.
Device embodiment described above only is schematic, wherein said unit as the separating component explanation can or can not be physically to separate also, such as the shielding conductor in the plug 35, (fastening part 34) elastic sheet metal 33 can be one, or the like.
Above disclosed only is a kind of preferred embodiment among the utility model embodiment, can not limit interest field with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
