Abstract
A misplug-proof electric connector-locking accessory comprises a guiding sleeve accessory and a guiding pin accessory. The guiding sleeve accessory is composed of a guiding sleeve, a screwed sleeve, an elastic gasket and a screw, wherein, the elastic gasket and the screw are firmly connected together and then installed in the screwed sleeve, the screwed sleeve and the guiding sleeve are firmly installed in the insulating body of an electric connector after being connected together, and according to different misplug-proof positioning codes, the guiding sleeve is fixed at different rotating positions. The guiding pin accessory is composed of a guiding pin, a gasket and a nut, and according to positioning codes corresponding to the guiding sleeve, the guiding pin accessory determines a rotating position and is then firmly installed into the insulating body of the electric connector. When the guiding pin accessory is inserted into the guiding sleeve accessory, the different rotating positions of the guiding accessories can effectively prevent misplug and ensure that an electric connector plug and a socket are reliably locked together after proper connection.
Description
Technical field
The utility model relates to a kind of error-preventing electric connector locking annex, belongs to technical field of electric connectors.
Background technology
In electronic equipment, the situation of a plurality of same electrical connectors is used in normal appearance simultaneously, connects in order to realize correct circuit, requires electric connector should have anti-mis-insertion and guide function.In addition, when printed circuit is connected with cable,, be free end, be subjected to the effect that pulls of cable, the disconnection that circuit connects takes place easily because the electric connector of cable end is unfixing.For this reason, except that requiring electric connector to have anti-mis-insertion and the guide function, also should be able to reliably lock, but be limited to the restriction of space and volume, in existing rectangular electric connector annex, have locking function after, often can not anti-mis-insertion, perhaps with after locking and anti-mis-insertion, the guiding separate design, the installing space that occupying volume is outer causes the increase of electric connector volume.
The utility model content
The purpose of this utility model is the deficiency that exists at existing electric connector accessory, and a kind of electric connector accessory that integrates anti-mis-insertion, guiding and locking function is provided.
The utility model anti-mis-insertion electric connector locking annex comprises fairlead annex and guide finger annex, the fairlead annex is made up of fairlead, swivel nut, elastic washer, screw rod, in elastic washer and the swivel nut of packing into after screw rod is fixedlyed connected, with pack into after fairlead is connected and be fixed in the insulator of electric connector, fairlead is fixed into different transpositions according to the location coding difference of its anti-mis-insertion; The guide finger annex is made up of guide finger, packing ring and nut, and guide finger is by the location coding corresponding with fairlead, determines pack into electric connector insulator and fix by packing ring and nut of transposition.
After adopting such scheme, when the utility model fairlead annex and guide finger annex plug together, can effectively prevent to misplug because of guiding attachment transposition difference, and can guarantee that electrical connector plug is connected the reliable locking after putting in place with socket.
Description of drawings
Fig. 1 is the principal section view of the utility model electric connector fairlead annex;
The principal section view of Fig. 2 the utility model electric connector guide finger annex;
Fig. 3 is that the utility model electric connector fairlead and guide finger annex plug together the principal section view after putting in place.
Among the figure: 1-fairlead, 2-swivel nut, 3-elastic washer, 4-screw rod, 5-guide finger, 6-packing ring, 7-nut.
Embodiment
Below in conjunction with the accompanying drawing example the utility model anti-mis-insertion electric connector locking annex is described in further detail:
The utility model anti-mis-insertion electric connector locking annex is made up of fairlead annex and guide finger annex, and the fairlead annex is made up of fairlead 1, swivel nut 2, elastic washer 3 and screw rod 4 as shown in Figure 1.Elastic washer 3 and screw rod 4 are packed in the swivel nut 2, break away from order to prevent elastic washer 3 and screw rod 4, have carried out turning over riveting in the end of swivel nut 2, make elastic washer 3 and screw rod 4 can not become part.After turning over riveting, swivel nut 2, elastic washer 3 and screw rod 4 form relatively independent parts---screw rod component.Fairlead 1 is non axial symmetrical part, according to the location coding of anti-mis-insertion, has determined the insulator of packing into after the transposition of fairlead 1, is threaded with the screw rod component then, and is fixed on the electric connector insulator, forms the fairlead annex.
The guide finger annex as shown in Figure 2, form by guide finger 5, packing ring 6 and nut 7, the shape of guide finger is corresponding with fairlead, guide finger 5 is by corresponding with fairlead 1 location coding, determined another insulator of electric connector of packing into after the transposition of guide finger 5, the packing ring 6 of packing into then, and fixing with nut 7.The fairlead annex is connected as shown in Figure 3 with plugging together of guide finger annex, the process of plugging together is at first to plug together with guide finger 5 guiding by fairlead 1 to put in place, rotating screw bolt 4 and guide finger 5 then, make screw-threaded engagement locking, elastic washer 3 was driven plain after locking put in place, prevented that screw rod 4 is loosening with being threaded of guide finger 5.
