Description
Technical field
The utility model relates to the parts on a kind of digital distribution frame, especially relates to a kind of improvement to easy to draw and insert electrical connectors structure.
Background technology
Connector is the important supporting component of control system, from system, subsystem, rack, printed circuit board (PCB) to each removable separate unit, thousands of connector is distributed in each system and position as people's nervous system, is undertaking electric energy transmitting, signal controlling and the transmission tasks of control system.Any one connector fault all will cause The whole control system or a certain control appliance can't operate as normal or stop labour.Usually require the not only necessary conducting in place of this conducting of contact site, and must contact reliable; Must reliable insulation to the place that the insulation position should not conducting.Light notices that the problem of insulation is not enough in fact, and connector requires and can rapid and reliablely plug in plug, guarantees safe and reliable use, and a lot of plug connector is not provided with these devices on connector, can not meet the demands even be provided with.
At present, on the communication main frame to the maintainability test of communication equipment, usually their access is finished by positioning link or conductor socket connector, after the user has connect line, because the tension of numerous service cables can force connector to produce irregular movement automatically, the location wild effect appears, can make test arrangement irregular, influence installation quality.The patent that someone applies for, patent is by name: " the auto-locking suspension positioning link (patent No. is: 95240340.4) ", it relates to the positioning link that connects security personnel row and test row on a kind of main frame of communicating by letter, it is made up of last locating shaft and following positioning rotating shaft, the last revolving fragment and the last stator of last locating shaft are hinged by the positioning sleeve that passes their centre bores, be installed with rotating shaft in the positioning sleeve, rotating shaft lower end and base plate are affixed, be with spring between its upper end step and the positioning sleeve upper surface, base plate upwards is fixed with an alignment pin at least, correspondingly last revolving fragment and on the stator correspondence position be provided with the concentric lock hole of matched in clearance.
But the inner wire jack structure of connector of test usefulness is two lobes, is testing when connecting, and that connector pin contacts with jack is unreliable, contact area is little, contact resistance is big, influences the indexs such as separating force, standard confining force, connect-disconnect life of connector.
Summary of the invention

Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: easy to draw and insert electrical connectors, it comprises connector, which is provided with an input and at least one output, the contact pin that jack that described input central authorities are provided with and described output central authorities are provided with matches, described connector and input and output are made as integrative-structure, and described jack is surrounded by at least 3 metal lobes.Testing when connecting, connector pin contacts with jack reliably, contact area is big, contact resistance is little, helps the separating force of connector and standard confining force, the connector connect-disconnect life is long.
As preferably, the periphery of described contact pin is provided with the number of metal lobe, is provided with insulating sleeve between contact pin and metal lobe, and described insulating sleeve is near metal lobe inboard.Between metal lobe and contact pin, insulating sleeve is set, and insulating sleeve and metal lobe is tightly linked, when contact pin being inserted carriers such as other connector, not can because of between be in contact with one another and produce short circuit phenomenon.One section space is arranged between contact pin and the insulating sleeve, be convenient to contact pin and can accurately insert input, and and the metal lobe form state of insulation, prevent that conductive materials from falling into input inside, make the peripheral metal of input contact the formation short circuit phenomenon with jack, be convenient to simultaneously form supporting with the contact pin of input.
As preferably, the periphery of described jack is provided with insulating sleeve; Described insulating sleeve is near the jack outside.Use the metal lobe to constitute jack and can remove to realize increasing contact area, the minimizing contact resistance of inner wire contact pin and jack by improving elasticity, the convergent force of connector, it is more reliable that they are connected.
As preferably, described jack has 4 metal lobes to constitute.Help realizing increasing contact area, the minimizing contact resistance of inner wire contact pin and jack, it is more reliable that their are connected.
As preferably, the described metal lobe when not inserting described contact pin constitutes conical tip and drops on the truncated cone-shaped on the line that extends axially outside the described jack.Help improving elasticity, the convergent force of connector.
As preferably, the nearly middle part of described contact pin is provided with bulge loop and some grooves, and an outer ring groove is to the pin diameter of the bulge loop side contact pin greater than other end part, and described contact pin small diameter portion carries out the transition to the major diameter place by the slope.Help forming the self-locking image when contact pin inserts jack, improve connection reliability.
Therefore, the utility model compared with prior art has following characteristics: 1, reasonable in design; 2, contact area is big, contact is more reliable, the connect-disconnect life height; 3, contact resistance is little, quality of connection is high, connects more convenient, more reliable; 4, good insulation preformance, safe in utilization, use occasion is wide; 4, connector is provided with band, and the coefficient of friction height in plug, is difficult for skidding, and is easy to use.
