Description

A kind of electrical connector

Technical field

The present invention relates to a kind of electrical connector.

Background technology

Electrical connector known today, major part are to utilize the elasticity of conducting metal self that the pressure of contact is provided, and after the elasticity of conducting metal weakens, are easy to cause loose contact; In small-sized or miniature connector, because the restriction of volume, even very thin of the sheet metal in the socket new, also is difficult to guarantee have enough pressure to guarantee reliable contact.

Another part connector is to utilize the elasticity of spring that the pressure of contact is provided:

1.1992 the elasticity connector that the French Marechal company that the article [industrial connector] of year the 1st phase " low-voltage electrical apparatus " is introduced produces;

2. I am in the patent of invention " moving contact power sour socket " (application number 200510107250) of application in 2005;

The first phase in 1992 " low-voltage electrical apparatus " the elasticity connector produced of the French Marechal company introduced is a kind of elastic force that utilizes spring keeps in touch two contacts under constant pressure an industrial connector: limit owing to stud with spring and the insulation crust that the copper rod of contact is enclosed in the outside in the socket, can only move up and down, so, realize the butt joint fully of entire contact surface between the contact, to processing, the required precision of installing is very high: the axis that studs with the copper rod of contact in the axis of latch and the socket must be parallel, two contact-making surfaces must be perpendicular to the axis of copper rod and latch, the upper surface of spring need guarantee also that with the cooperation of copper rod joint the contact-making surface of two contacts must be parallel, otherwise, be not easy the contact of formation face.

My application number is 200510107250 patent of invention " moving contact power sour socket ", because the metal contact is to join with latch from the side, the position and the size restrictions that add upper spring, it is very little to make that the size of connector can't be done, the arcing in the time of also can't eliminating the contact disjunction simultaneously.

Summary of the invention

The objective of the invention is to provide a kind of processing simple, contact reliable electrical connector.

According to the present invention, these targets are achieved by the following scheme: a kind of electrical connector comprises insulating base frame, spring, contact chip and lead-in wire.

Described electrical connector, the hole that at least more than one is arranged on insulating base frame, the top in hole is the jack 5 of the circle of latch insertion, the square hole 7 that the middle part in hole is, in square hole 7, have one can be movable metal contact 6, the bottom in hole is a circular hole 9 of placing spring, and a stage clip 10 is arranged in

circular hole

9,10 1 ends of stage clip withstand on the bottom of circular hole 9, and the other end withstands in the pit 8 of metal contact 6.

Metal contact 6 is square sheet metals, and the one side of sheet metal is a plane, and there is a pit 8 at the middle part of another side, is welded with lead-in wire 11 on the edge of pit, and the lead-in wire 11 that is welded on the metal contact 6 is drawn from square opening 7 with helical form.

When making high-power plug part, because the elastic force that is subjected on the metal contact 6 only acts on the central point, so, when latch inserts, even two planes of the end face of the latch that causes because of machining accuracy and movable contact flat are slightly not parallel, movable contact flat can be adjusted the angle of self automatically under the acting in conjunction of spring force and latch ends surface pressure, with latch end face close proximity, guarantee the reliability of the connection of two contact-making surfaces.

When latch is outwards extracted, because movable contact flat has been sealed the bottom nozzle of insulation jack 5, make to have formed local vacuum in the jack, alleviated the harm that arcing causes.

When making miniature connector, metal contact 6 and lead-in wire 11 can save, and directly use the spring of the metal that is coated with excellent conductive performance as connector.

Owing to the outside diameter of spring can be accomplished less than 0.5mm, but still can provide enough elastic force, make the reliability of miniature plug part be guaranteed.

The invention will be further described below in conjunction with accompanying drawing and example:

Fig. 1 is the structural representation that the present invention has metal contact 6;

Fig. 2 is the structural representation that the present invention does not have one group of miniature contact of metal contact 6;

In Fig. 1 and Fig. 2, the 4th, the lock pin of plug, the 5th, the jack on the insulator, the 6th, metal contact, the 7th, the square hole in the insulator, the 8th, the pit on the metal contact, the 9th, lay the circular hole of spring, the 10th, spring, the 11st, lead-in wire, the 12nd, the small through hole that supplies single spring or lead-in wire to pass on the insulator.

Embodiment one: spring 10 is placed in the circular hole 9 on the insulator, one end withstands on the bottom of circular hole 9, the other end withstands in the pit 8 on the metal contact 6, the metal contact 6 that is welded with lead-in wire 11 is withstood on the bottom of latch jack 5 by spring 10, one end of lead-in wire 11 is welded on the metal contact 6, and the other end passes from hole 12 with helical form.

The principle of embodiment one is: when latch does not insert, one end of spring 10 withstands on the bottom of circular hole 9 on the insulator, the other end withstands in the pit 8 of metal contact 6, utilize elasticity metal contact 6 to be withstood on the bottom of jack 5, because the size of metal contact 6 is greater than the diameter of jack 5, so sealed jack 5; Because spring 10 is very little with respect to the size of metal contact with the diameter of metal contact 6 joints, can think that elastic force just acts on the central point of metal contact 6.When latch inserts jack and is urged to metal contact 6, metal contact 6 is with the downward extrusion spring 10 of latch, at this moment, if the front end face of latch and movable contact flat are not parallel, then certain of latch front end face outer is a bit inevitable contacts with the corresponding elder generation of putting on the movable contact flat, just be subjected to the effect of two power this moment on the metal contact 6: one is the elastic force of the spring that makes progress that is subjected to of center, another is the pressure of the downward latch that is subjected to of edge, along with latch moves down, the result of two power effects makes metal contact 6 progressively change the state of oneself, finally joins with the end face of latch is parallel; When latch is inserted into, utilize fixture to make latch, metal contact and spring be in stable state, because the shift invariant of spring, so that the contact pressure of latch and metal contact 6 is also kept a steady state value is constant; When outside plug pin, metal contact 6 moves up with latch under the effect of spring 10, until the bottom that is blocked in pin hole 5, at this moment, continue the latch outwards extract,, make that the end face from moment that the end face of latch leaves metal contact 6 to latch is pulled out pin hole 5 these sections in the period just as the piston in the vacuum pump, in pin hole 5, form low pressure, reduced the harm that arcing may cause.

Embodiment two: Fig. 2 is small-sized or the schematic diagram of miniature connector, in the jack 5 of insulator, is placed with the spring that miniature sizes, skin are coated with gold, silver or copper, and an end of spring passes outside the insulator by hole 12, so that welding lead.When latch inserted, the end of latch forced length of spring compressed, and when displacement was constant, the power that the end face of latch is subjected to also was constant.

The description of above embodiment only is used for explanation of the present invention is not construed as limiting the invention.
