Abstract
The invention relates to a connector for servo motor power cables and coder cables. The connector comprises a shell and a cable. The cable stretches into the shell and is fixedly connected with the shell. The connection portion of the cable and the shell and at least one part of the outer surface of the shell are wrapped with nonmetal sheaths. The cable and the shell form a closed integrated structure through the nonmetal sheaths. The nonmetal sheaths stretch in the direction from the shell to the cable to form tubular extension ends. The shell comprises a right-angle type hollow tubular shell body and a straight-line type hollow tubular shell body. Hot melting glue layers are arranged between the nonmetal sheaths and the outer surface of the shell and between the extension ends and the outer surface of the cable respectively. The nonmetal sheaths and the shell are bonded to and fixed to the cable through the hot melting glue layers. The cable connector is good in airtightness, reliable in reliability and capable of preventing liquid and dust from entering the interior of the connector, and thus the service life of products is prolonged effectively.
Description
Technical field
The present invention relates to servomotor connector, specifically a kind of power cable connector for servomotor and encoder cable connector.
Background technology
At present, the cable connector for servomotor generally includes power cable connector and encoder cable connector.This kind of cable connector mainly contains two kinds of structures: one is be provided with at the housing port of cable inserting end the nut be connected with port external screw thread, tapered sleeve is provided with between shell inner hole and the cable of its fit, fastening nut, extruding tapered sleeve, tapered sleeve tightens up cable, and cable and housing are fixed, and avoids cable to move in housing and causes the terminal junction in cable and inner core to loosen, thus avoid producing loose contact phenomenon, also play certain sealing function simultaneously.But said structure exists lower column defects: 1, in use procedure, nut easily loosens, and loses the fixation to cable, and cable moves in housing, cause the terminal junction in cable and inner core to loosen, produce loose contact phenomenon; 2, the junction of housing and cable is poorly sealed, and liquid, dust easily enter.Therefore cause the cable connector reliability of said structure lower.
The structure of another kind of cable connector is provided with at the housing port of cable inserting end the nut be connected with port external screw thread, cable outside housing port is set with bellows, at nut, tightener is provided with between corrugated tube port outer wall, fastening nut, corrugated tube port is fixedly connected on housing port, bellows is closed between the housing port of cable inserting end and cable, play certain sealing function, but in this structure except there is the defect of front a kind of structure, also there is lower column defects: 1, the cable stretching into shell inner hole is not fixed, cable can move in motion process in housing, the terminal junction in cable and inner core is caused to loosen, produce loose contact phenomenon, 2, bellows and connector junction poorly sealed, liquid, dust easily enter connector inside, cause fault.The cable connector reliability of this structure is caused to reduce equally.
Because the environment for use of servomotor is comparatively complicated, the dependability for cable connector requires higher, and current existing cable connector often can not reach this instructions for use, needs to improve and optimize.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of connector for servomotor power cable and encoder cable is provided, this connector is by after effectively fixing the cable stretched in housing, put on the inherent injection molding machine of mould and fill with upper gum cover by all sealing except the remainder connecting servomotor socket part, good airproof performance, reliability is high.
The object of the invention is by realize by the following technical solutions:
For the connector of servomotor power cable and encoder cable, comprise power cable connector and encoder cable connector, described power cable connector and encoder cable connector comprise housing and cable respectively, cable stretches in housing and is connected with housing and fixes, the cable of described power cable connector or encoder cable connector and the junction of housing and housing outer surface be enclosed with non metallic sheath at least partially, described non metallic sheath makes to be connected to form airtight overall structure between cable and housing.
As the preferred technical solution of the present invention, the cable of described power cable connector and encoder cable connector and the junction of housing and housing outer surface be all enclosed with non metallic sheath at least partially; Described non metallic sheath comprises rubber sheath and plastic sheath.Described non metallic sheath to be extended to cable direction by housing and forms the extended end of tubulose.Be equipped with hot melt adhesive layer between described non metallic sheath and the outer surface of housing and between described extended end and the outer surface of cable, described hot melt adhesive layer is by non metallic sheath and housing and cable bonds and fix.
Described housing comprises perpendicular type hollow tubular housing and linear pattern hollow tubular housing.Described non metallic sheath is wrapping to the outer surface of cable connector housing and the cable outer surface near housing by encapsulate technique.The housing outer surface of described cable connector comprises joint face for patching and disconnected, and disconnected of described housing is all enclosed with non metallic sheath.
Encapsulate technique comprise the housing parts of this connector, coupling part and cable are installed fixing after, put into mould, by injection molding machine by except the remainder sealing pouring adhesive cover connecting servomotor socket part, make between cable and housing, to be connected to form airtight overall structure.Cable outside a part for housing and housing and gum cover equidimension part coat hot melt adhesive layer before putting into mould, and hot melt adhesive layer, when putting into mold injection gum cover, can melt and gum cover and housing and cable outer surface are bondd and sealed.
Beneficial effect of the present invention: relative to prior art, the present invention has the following advantages:
1, connector forms integrally-built plastics or rubber sheath by encapsulate, and connectivity port cable being stretched into housing seals completely, and liquid, dust can not enter connector inside.In use procedure, connector there will not be because of the problem loosening impact sealing that is threaded, and significantly improves the reliability of sealing; On the other hand, cable and housing are fixed, and avoid cable mobile cable and inner core terminal junction of causing in housing to loosen, thus avoid producing loose contact phenomenon.Therefore, the dependability of connector is significantly improved.
2, cable is by hot melt adhesive layer and sheath and housing bonds and fixing, and intensity is higher, improves the reliability sealed between cable and housing further, can prevent liquid equally, dust enters connector inside, thus effectively extend the useful life of product.
