Description
Technical field
The utility model relates to a kind of electric connector.
Background technology
As shown in Figure 1, a kind of like this electric connector is arranged at present, this electric connector comprises procapsid 14 and back casing 15, and semicircle connecting ring 6 fixed card by two make-ups after forward and backward housing 14,15 is pegged graft are connected together.Before being provided with perforation in the procapsid 14, after cavity, this cavity comprises the insulator installation cavity of leading portion and the lead container cavity of rear end, the front end of insulator installation cavity is provided with a ring platform, ring platform place axial thrust is equipped with a preceding insulator 11, insulator 12 after the rear end of preceding insulator 11 is equipped with one, fixedly be fitted with contact 5 between preceding insulator 11 and the back insulator 12, the bonding wire end of contact 5 passes the rear end face of back insulator 12, the rear-locating face place of back insulator 12 is provided with a jump ring 13 that is installed in the procapsid 14, before jump ring 13 is incited somebody to action, back insulator 11,12 connect as one with procapsid 14.This connector in use, at first semicircle connecting ring 6 is taken off, unplug forward and backward housing 14,15 then, afterwards the rear end of cable 8 from back casing 15 penetrated, and pass and leave certain welding surplus from the front end of back casing 15, by the cable immobilizing structure in the back casing cable 8 and back casing 15 are fixed together then, again the lead 7 of cable 8 are welded on the contact 5 afterwards.Because contact 5 is fixed in the procapsid 14 by forward and backward insulator 11,12, forward and backward housing 14,15 has only and separates certain distance and just can weld, therefore, long bonding wire surplus must be left at the front end of back casing 15 and the bonding wire operation could be normally carried out.Behind to be welded the finishing, again forward and backward housing 14,15 is inserted to together, because there is long welding surplus in lead 7, in the whole tortuous cavitys that are squeezed in forward and backward housing 14,15 joints of the welding surplus of lead 7, the easy like this problem that causes solder joint to break away from, in addition, tortuous lead also can produce the phenomenon of crosstalking.
The utility model content
The purpose of this utility model provides and a kind ofly can not occur the tortuous extruding of lead in housing junction, front and back and cause solder joint to break away from and can not produce the electric connector of crosstalking.
For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector, comprise procapsid, back casing, contact and insulator, be provided with in the described procapsid and connect forward and backward cavity, this cavity comprises the insulator installation cavity of leading portion and the lead container cavity of back segment, and the insulator correspondence is installed in the insulator installation cavity, and correspondence is provided with supporter in the described lead container cavity, the front end of supporter cooperates with the insulator pushing tow, and the rear end of supporter cooperates with the back casing pushing tow.
Described supporter is an open sleeve, and what the side face of open sleeve was provided with pass through openings sleeve front and back end crosses the line opening, and this is crossed the line opening and enters the inlet of open sleeve for the lead that welds together with contact.
Described supporter is at least one support chip that circumferentially is provided with along the lead container cavity.
The side face of described open sleeve and procapsid corresponding matching is provided with lead key and the guide groove that cooperatively interacts.
Described open sleeve is provided with protruding key and the groove that cooperatively interacts with the end face that back insulator pushing tow cooperates.
The side face of described procapsid and preceding insulator corresponding matching is provided with positioning key and the location notch that cooperatively interacts.
The electric connector of such scheme in use, at first cable is passed back casing and reserve suitable weld length at the front end of back casing, by the cable immobilizing structure in the back casing cable and back casing are fixed together afterwards, to intert then in the back contact in the insulator and cable welding ends wire bonds together, after to be welded the finishing, the open sleeve cover is installed to the bonding wire place of cable, afterwards preceding insulator is placed on the front end face of back insulator, and align itself and position relation of back insulator, be right after again procapsid suit is successively crossed preceding insulator, back insulator and open sleeve, and finally be plugged on back casing, and then with the semicircle connecting ring of two make-ups procapsid and back casing fixed card are connected together, promptly finished the bonding wire assembling of this connector this moment.After finishing assembling, the front end of open sleeve cooperates with back insulator pushing tow, and the rear end of open sleeve cooperates with the back casing pushing tow, and in the procapsid, open sleeve has played the effect of jump ring in the existing product to open sleeve with back insulator fixed constraints like this.Because after having adopted said structure, when welding lead on contact, owing to there be not blocking of procapsid, satisfy the contact afterbody to the distance between the back casing as long as reserve the weld length of cable, no longer need to reserve unnecessary welding surplus, like this, after forward and backward housing is pegged graft, the tortuous extruding phenomenon that promptly can not occur lead in the junction of forward and backward housing, avoided causing solder joint to come off because of the tortuous extruding of lead, in addition, also avoided the crosstalk phenomenon that produces because of lead is tortuous.
Improve as an other top of the present utility model, on the side face of procapsid and preceding insulator corresponding matching, be provided with positioning key and the location notch that cooperatively interacts, positioning key and location notch cooperation have guaranteed that contact has fixing coordinate figure in procapsid, the phenomenon with respect to housing generation relativity shift can not occur.Also have, be provided with lead key and the guide groove that cooperatively interacts on the side face of open sleeve and procapsid corresponding matching, lead key cooperates with guide groove, plays the effect of guiding when open sleeve and procapsid assemble, and is convenient to open sleeve and ends spinning and be assigned in the procapsid.
