Description
The utility model is a kind of wire and cable connector, relates in particular to a kind of locking and earthing component that is used for the wire and cable connector of telecommunication conducting between two electronic systems.
Documents such as No. the 81210869th, 84206625, Taiwan patent disclose a class and have been applied to the wire and cable connector that telecommunication connects between two electronic systems; this class wire and cable connector is typically provided with the metal shielding casing; the electric connector insulating body that dress can be inserted with conducting terminal envelopes the purpose of covering protection to reach; and the masked segment formation that can cooperate cable current-carrying part periphery to be coated is comprehensively covered effect; and this shielding casing further is assembled in the outer cover, thereby is assembled into a complete wire and cable connector.And when usually cable transmits telecommunication between two electronic systems; because electromagnetic action usually can be assembled on cable and wire and cable connector and port thereof a certain amount of electrostatic charge is arranged; these electrostatic charges can influence the quality of telecommunication transmission in the cable; so when serious even the normal operation of entail dangers to electronic system; this type of wire and cable connector is being provided with outside the aforesaid various member; usually also can suitably be provided with grounding construction; by its earthed circuit conducting default, the conduction of the static on cable and the wire and cable connector can be eliminated with docking electronic installation.A kind of common earthing mode of existing wire and cable connector be its outer cover with respect to a side of butt joint electronic installation on installing one metal cap lid; but this metal cap lid cover cap is in insulating body and all sides of docking the electronic installation butted part; and electrically contact with the shielding casing that is coated on the insulating body outside; ground path set in the cable then electrically conducts with this shielding casing; contact conducting by this cover cap body with the grounded part of butt joint electronic installation during butt joint; and the further ground connection conductive path of conducting cable, thereby reach the effect of ground protection.
But, because the existing set ground connection conductive path of wire and cable connector is by the ground path conducting of links such as metal cap lid and shield shell ability with cable, in case phenomenons such as loose contact or disengaging appear in wherein some conducting contacts, promptly can have influence on cable and wire and cable connector and eliminate the effect of static, and cause the telecommunication laser propagation effect not good.Especially for the metal cap lid, because this cover cap body is plugged into wire and cable connector on the butt joint electronic installation by the operator passively and is just contacted in the docking operation, cause wire and cable connector to contact insufficient if the operator is firmly not enough with the butt joint electronic installation, this moment, the cover cap body might not contact with the metal part branch of electronic installation, cause set ground connection conductive path can't normally bring into play the effect that it eliminates static, and influence the effect of telecommunication transmission in the cable.In addition, when the cover cap body is connected to the grounded part of butt joint electronic installation, conducting terminal in the electric connector docking section also almost simultaneously and the electrical part conducting of docking electronic installation, thereby, electrostatic charge is directly entered in the electronic installation, and in specific dry environment, this electrostatic charge might be up to tens of volts, even hundreds of volts, very easily the element in the electronic installation is caused damage beyond remedy.
The purpose of this utility model is to provide a kind of wire and cable connector with locking component, its locking component when butt joint can be all the time with dock electronic installation and keep electrical state of contact, to guarantee the unimpeded of ground path, and it can further be fixed on wire and cable connector on the butt joint electronic installation, so as to reaching the purpose of eliminating electrostatic interference, guaranteeing telecommunication stable transfer quality.
In order to reach above-described purpose, the utility model wire and cable connector is provided with jockey, assembly such as outer cover and locking component, wherein insulating body one side of electric connector is provided with the docking section, contain on this docking section plurality of conductive terminals and can with dock electronic installation and be electrically conducted, this electric connector can further be assembled in the outer cover, this outer cover is provided with craft port with respect to a side of insulating body docking section, can powering, the docking section of connector is protruding to be exposed in it to dock plug, and relative opposite side then is provided with through hole for connecting and the fixed cable end.Of the present utility model being characterised in that, the appropriate position, craft port both sides of outer cover respectively is assembled with locking component, this locking component is provided with elastic device, and ground path set in one end and the cable is connected conducting, its relative other end end then is provided with holding unit, during butt joint because the effect of elastic device, this locking component can protrude out automatically outside the outer cover and keep electrically contacting with the earthed circuit of butt joint electronic installation, and wire and cable connector can be fixed on the butt joint electronic installation, eliminate static and the purpose of guaranteeing the signal stable transfer thereby reach ground connection.
According to described feature, locking component specifically includes assemblies such as screw rod, spring, contact ring and baffle ring, wherein screw rod one end is equipped with an insulation turn portion of expanding, relative other end surface then is distributed with the screw thread of suitable length, and is being provided with a ring-type draw-in groove near on the surface, appropriate location of screw thread between the two ends.On screw rod, be provided with contact ring, spring and the baffle ring that is connected with the ground path of cable respectively successively from turn portion one end.Screw rod can be assembled in outer cover the port both sides in the corresponding circular groove that is provided with, and make both ends of the spring be resisted against the set accommodation space both sides of outer cover respectively, borrow its elastic force that screw rod can be protruded outside the outer cover under nature automatically, then be collapsible in the outer cover during compression spring.The set screw thread in this locking component one end can lock by the screw set with docking electronic installation when butt joint; the two of docking can be fixed together; and while and the earthed circuit conducting of docking electronic installation, thereby reach good ground protection effect and guarantee the stability that telecommunication is transmitted.
Owing to adopt above-described design, the utility model wire and cable connector when butt joint can be lasting with docking the electronic installation maintenance automatically electrical state of contact and guarantee the unimpeded of ground path, more can further wire and cable connector be fixed on the butt joint electronic installation, thereby it is eliminated electrostatic interference and guarantees that the effect of telecommunication transmission stability is more better than existing wire and cable connector.
