Abstract
The invention discloses an elastic pin. A plug mainly comprises an insulating housing, pins, a rubber spring, and insulating press blocks. The rubber spring is a rectangular rubber piece, made by the aid of elastic deformation of the rubber. The insulating press blocks are made of strip or T-shaped plastic pieces or rubber pieces with one larger end and a smaller one. The pins are made of elongated metal copper sheets or elongated cylindrical metal copper rods. The insulating housing is a soft or hard. The insulating housing is provided with pin holes, a spring cavity and insulating press block holes. The pins are fixed in the pin holes. The rubber spring is placed inside the spring cavity and abutted to the pins. The insulating press blocks are fitted in the insulating press block holes in two sides of the insulating housing, with the larger ends pressed against the pins. The elastic pins which are simple in structure and good in insulating effect are applied, so that the pins are easy to insert into a power strip, with no spark occurring, the inserted pins can contact well stably, and both the power strip and the pins are resistant to erosion and durable.
Description
Technical field
The present invention relates to a kind of elastic contact pin.
Background technology
The contact pin using now, because two metal ferrules do not have elasticity, does not have elastic insert yet between two metal ferrules, cause in the pin holes of wiring plate elastic contact chip loosening or insert contact pin while following the string, and easily produces electric spark or loose contact.
Summary of the invention
The object that the present invention relates to is in order to provide a kind of easy to use and have manufacture and a method thereof of the contact pin of elastic dilatation when inserting.
For achieving the above object, described elastic contact pin mainly comprises insulation shell, contact pin, rubber spring, insulation pressing.Described rubber spring is the block rubber of the shape of cuboid, utilizes rubber strain to make spring; Insulation pressing is one end is large, one end is little bar shaped or unit of plastic or the block rubber of T shape; Contact pin is the metal copper sheet of strip or the metal copper rod of elongated cylindrical, can be solid bar while being metal copper rod, can be also hollow bar; Insulation shell can be the soft shell that rubber is made, and can be also the duricrust that plastics are made.
In insulation shell, have pin holes, spring cavity and insulation pressing hole, contact pin is fixed in pin holes, and rubber spring is put into spring cavity and propped up contact pin, and insulation pressing packs in the insulation pressing hole of insulation shell both sides and is pressed on contact pin with large one end.
Before inserting wiring plate, first firmly card is pressed insulation pressing, make the rubber spring compression between two contact pins, when the gap between two contact pins is just the gap of two jacks on wiring board, elastic contact pin is inserted in the pin holes on wiring board, unclamp again and press after insulation pressing, rubber spring return and the sheet metal in the pin holes of contact pin and wiring board is contacted, connection circuit.While transfering to contact pin, first card is pressed insulation pressing, make rubber spring compression and easily acquisition approval go out elastic contact pin.
In order to improve the insulation effect of elastic contact pin, the material of the rubber spring of described elastic contact pin can be done by the resilient rubber of apparatus, also can make of resilient plastics.
In order to improve elastic dilatation power and the fixing convergent force of the metal ferrule of elastic contact pin, the rubber spring of described elastic contact pin can be made strip, also can make annular ring or degree of lip-rounding circle, can also make side with the annular ring or the degree of lip-rounding circle that protrude.
Elastic contact pin of the present invention simple in structure, insulation effect good; Adopted after elastic contact pin, convenient when contact pin inserts wiring board, produce no spark, after inserting, contact stabilization is good, makes wiring board and contact pin all be not easy ablation, durable in use.
Accompanying drawing explanation
Fig. 1 is the structure cross-sectional schematic of elastic contact pin of the present invention.
Embodiment
Elastic contact pin of the present invention mainly comprises insulation shell 1, contact pin 2, rubber spring 3, insulation pressing 4.Described rubber spring 2 is block rubbers of the shape of cuboid, utilizes rubber strain to make spring; Insulation pressing 4 is one end is large, one end is little bar shaped or unit of plastic or the block rubber of T shape; Contact pin 2 is the metal copper sheet of strip or the metal copper rod of elongated cylindrical, can be solid bar while being metal copper rod, can be also hollow bar; Insulation shell 1 can be the soft shell that rubber is made, and can be also the duricrust that plastics are made.
In insulation shell 1, there are pin holes and spring cavity, contact pin 2 is arranged in pin holes, rubber spring 3 is installed in medi-spring chamber and is withstood on contact pin 2 or be enclosed within on contact pin 2 and is arranged in pin holes again, and insulation pressing 4 is arranged on the both sides of insulation shell 1 and is pressed on contact pin 2.
In order to improve the insulation effect of elastic contact pin, the material of the rubber spring 2 of described elastic contact pin can be done by the resilient rubber of apparatus, also can make of resilient plastics.
In order to improve elastic dilatation power and the fixing convergent force of the metal ferrule of elastic contact pin, the rubber spring 2 of described elastic contact pin can be made strip, also can make annular ring or degree of lip-rounding circle, can also make side with the annular ring or the degree of lip-rounding circle that protrude.
Elastic contact pin of the present invention is before inserting wiring plate, first firmly card is pressed insulation pressing 4, make rubber spring 3 compressions between two contact pins 2, when the gap between two contact pins 2 is just the gap of two jacks on wiring board, elastic contact pin is inserted in the pin holes on wiring board, unclamp again and press after insulation pressing 4, rubber spring 3 returns and the sheet metal in the pin holes of contact pin 2 and wiring board is contacted, connection circuit.While transfering to contact pin, first card is pressed insulation pressing 4, makes rubber spring 3 compressions and easily transfers to elastic contact pin.
