Abstract
The invention provides an electrical appliance socket connector, belongs to the fields of electronics and electrical engineering, and particularly relates to the fields of electrical connection between cables and cables or cables and electronic devices. The tighter the matching between the plug jack and contact pin of an electrical connector is, the smaller the contact resistance is, but the abrasion while plugging is large, then the contact resistance is increased and the plugging life is shortened, thus a contradiction is existed between the resistance reducing and the service life prolonging. The electrical appliance socket connector comprises electric conduction plug jacks and a plug jack fixing board, wherein the jack end of each plug jack is provided with a plug jack seam opened from the jack center to the jack bottom, the periphery of the seam part of each plug jack is filled with silicone rubber, the outer wall of each plug jack is in direct contact with the silicone rubber, the upper end surface of the silicone rubber is in contact with a pressing cover, the circumferential surface of the silicone rubber is in contact with the inner surface of a cylinder, the distance between the end surface of the cylinder and the upper surface of the plug jack fixing board is 3 mm, and the distance between the upper surface of the pressing cover and the upper surface of each plug jack is 2 mm. The electrical appliance socket connector is mainly used for electrical connection.
Description
Technical field
The invention belongs to electronics, electrical engineering field, particularly conduct electricity a kind of connector that is connected between cable and cable or between cable and electronic device.
Background technology
Electrical connector is with conducting electricity a kind of electric connector that is connected between cable and cable or between cable and electronic device in electronics, the electric field.Electric connector is made up of plug, two ones of sockets, and its inner main part is contact pin and jack, and they can exchange.The current techniques situation is: China Aviation Optical-Electrical Technology Co., Ltd of China Aviation Industry Corporation I (158 factories, network address: be one of the main enterprises of producing by electric connector WWW.lhgd.con.cn), and make contributions for Chinese first manned spaceflight.National military standard GJB598.GJB599 etc. is imitated U.S. army mark MIL-C-26482 and the serial product of MIL-C-38999 in the product of the said firm's highest level; Do not surmount the U.S. army mark part; Because improving constantly of instructions for uses such as aircraft, guided missile, spacecraft; Each state is all developing and using better electric connector, and is only not open to the army's of listing in target stage.In the electric connector of using now when inserting contact pin the internal diameter of jack be unshrinkable, for spininess can plug simultaneously, and arranged certain life-span; Contact pin has certain interval with cooperating of jack; In machining, be called movingly, electric connector often all needs frequent plug, also can cause the wearing and tearing in pin, hole; The existence of this situation causes contact resistance to increase problems such as heating unavoidablely.The jack of electric connector cooperates tight more with contact pin, contact resistance is more little, but when plug wearing and tearing are big, and contact resistance becomes big thereupon, and connect-disconnect life shortens, thereby to reduce resistance be contradiction with increasing the service life.
Summary of the invention
The purpose of this invention is to provide a kind of electrical connector, it can solve electric connector effectively and use resistance lower, the technical problem of plug longer service life.
The object of the invention is realized that by following technical scheme the method that the present invention solves this contradiction is that jack is open in the contact pin insertion process, and it is little to wear and tear, and the jack internal diameter shrank when contact pin was inserted into, compressed contact pin, and resistance is little.Be lower than existing electric connector resistance, the plug longer service life.Electrical connector comprises conductive jack and jack fixed head; The nose end of jack has the jack seam at the bottom of a via hole heart reaches the hole, and each jack has the filling silicon rubber on every side of seam part, and the jack outer wall directly contacts with silicon rubber; The upper surface of silicon rubber contacts with gland; The circumferential surface of silicon rubber contacts with the inner surface of cylinder, and the end face of cylinder and jack fixed head upper surface distance are 3mm, and the gland upper surface is 2mm to the distance of jack upper surface.Plug is the same with existing product, and when plug insertion just was dark, jack was a horn mouth; Contact pin and Socket walls wearing and tearing are little, when plug is tightened the gland that presses down socket, and silicon rubber lateral expansion power extruding jack outer wall; Jack tightly bonds contact pin, unscrews hold-down nut when extracting earlier, and jack opens.This structure wearing and tearing are little, and contact resistance is also little, has extended cycle life, and has solved contradiction preferably.
The invention has the beneficial effects as follows with existing electric connector mutually specific energy reduce the contact resistance of contact pin and jack and improve and plug cycle life.
Description of drawings
Fig. 1 is a partial sectional view of the present invention.
Fig. 2 is that the A of Fig. 1 is to zoomed-in view.
Embodiment
The contrast accompanying drawing further specifies below, is contained in the socket with jack, is threaded to example at present.
Fig. 1 is the partial sectional view of socket, has only drawn a jack, and Fig. 2 is that the A of Fig. 1 is to zoomed-in view.Outside the same with existing product.The nose end of jack 1 has the jack seam 2 at the bottom of a via hole heart reaches the hole; Each jack 1 has the filling silicon rubber 4 on every side of seam part, and jack 2 outer walls directly contact with silicon rubber 4, and the upper surface of silicon rubber 4 contacts with gland 6; The circumferential surface of silicon rubber 4 contacts with the inner surface of cylinder 5; The end face of cylinder 5 and jack fixed head 3 upper surfaces distance are 3mm, and with what silicon rubber elastic compression, gland 6 upper surfaces are 2mm to the distance of jack 2 upper surfaces.Utilize the plastic deformation of jack 2 materials that jack 2 flare ups are tubaeform.Jack 2 still is fixed on the jack fixed head 3 with existing product is the same.Plug is the same with existing product; When plug insertion just was dark, jack 2 was horn mouths, and contact pin and Socket walls wearing and tearing are little; When plug is tightened the gland 6 that presses down socket; Silicon rubber 4 lateral expansion power (direction of arrow among the figure is the direction of expansive force) extruding jack 2 outer walls, jack 2 tightly bonds contact pin, and jack 2 opens when extracting.This structure wearing and tearing are little, and contact resistance is also little, has extended cycle life.Solved contradiction preferably.
Above structure also is applicable to aviation plug, electric connector for socket, because of basic structures such as contact pin, jack are the same.
