Abstract
The utility model discloses a waterproof POGO pin. The waterproof POGO pin includes pins, O-shaped sealing rings and an insulating body; the insulating body is provided with stepped holes penetrating two sides of the insulating body; the pins are mounted in the stepped holes; cylindrical surfaces adjacent to the bottoms of the pins are provided with waterproof grooves; the ratio of the depth of the waterproof grooves to the diameter of the section of the O-shaped sealing rings is in a range of 0.6 to 0.8; the ratio of the cross-sectional area of the waterproof grooves to the cross-sectional area of the O-shaped sealing rings is in a range of 0.85 to 0.9; and after being subjected to tensile deformation, the O-shaped sealing rings are mounted in the waterproof grooves. The O-shaped sealing rings made of silicon rubber are additionally arranged around the pins, and a rubber filling method which is adopted to process the joints of the pins and the insulating body is replaced, and therefore, a sealing performance can be realized, and dust, air and water vapor can be prevented from penetrating equipment, and therefore, the equipment can be protected; the waterproof POGO pin is advantageous in simple and practical structure, low cost and easy use.
Description
Technical field
The utility model relates to a kind of POGO PIN, particularly a kind of waterproof POGO PIN.
Background technology
POGO PIN is a kind of electric installation, is applicable in the various electronic components that need to be electrically connected to.This contact head structure is small and exquisite, conductivity is strong, and economic and practical, so be suitable for widely in a lot of electronic components, medicine equipment.
At present in industry, generally in PIN pin and the method for insulator junction employing encapsulating, realize being connected of PIN pin and insulator, this method of attachment is after misoperation or glue inefficacy, be easy to allow dust, steam etc. be penetrated in equipment, thereby affect the serviceability of equipment, damage equipment even.
Utility model content
For solving the problems of the technologies described above, we have proposed a kind of waterproof POGO PIN, its object: prevent that dust and steam etc. are penetrated in equipment.
For achieving the above object, the technical solution of the utility model is as follows:
A POGO PIN, comprises PIN pin, O RunddichtringO and insulator, and insulator is provided with the shoulder hole that connects both sides, and PIN pin is arranged in described shoulder hole;
On the face of cylinder near PIN pin bottom, be provided with waterproof groove, the ratio of the diameter of section of the degree of depth of waterproof groove and O RunddichtringO is 0.6-0.8, the ratio of the sectional area of the sectional area of waterproof groove and O RunddichtringO is 0.85-0.9, after the stretcher strain of O RunddichtringO, is installed in waterproof groove.
Preferably, the material of O RunddichtringO is silicon rubber material.
In order to make O RunddichtringO have better sealing, described silicon rubber is methyl vinyl silicone rubber.
Pass through technique scheme; the utility model provides a kind of waterproof POGO PIN; at PIN pin, be added with O RunddichtringO around; replaced original method at PIN pin and insulator junction employing encapsulating; reach the effect of sealing; prevented that dust, air and steam etc. are penetrated in equipment, thereby played the effect of protection equipment.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structure chart of a kind of waterproof POGO PIN disclosed in the utility model;
Fig. 2 be Fig. 1 along A-A to generalized section.
Numeral and the represented corresponding component title of letter in figure:
1.PIN pin 11. waterproof groove 2.O RunddichtringO 3. insulators
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Below in conjunction with schematic diagram, embodiment of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of waterproof POGO PIN, comprises PIN pin 1, O RunddichtringO 2 and insulator 3, and insulator 3 is provided with the shoulder hole that connects both sides, and PIN pin 1 is arranged in described shoulder hole, reaches the effect of firm plug.
On the face of cylinder near PIN pin 1 bottom, be provided with waterproof groove 11, the ratio of the diameter of section of the degree of depth of waterproof groove 11 and O RunddichtringO 2 is 0.7, the ratio of the sectional area of the sectional area of waterproof groove 11 and O RunddichtringO 2 is 0.88, after 2 stretcher strains of O RunddichtringO, be installed in waterproof groove 11, rely on the elastic force of O RunddichtringO 2 that O RunddichtringO 2 is tightly placed in waterproof groove 11, PIN pin 1 is packed in insulator 3, by the step on insulator 3 and PIN pin 1, locate, O RunddichtringO 2 is subject to the extruding of the outer wall of waterproof groove 11 on the shoulder hole inwall of insulator 3 and PIN pin 1, the outer wall of waterproof groove 11 on the shoulder hole inwall of insulator 3 and PIN pin 1 is close in distortion, reach the effect of sealing, prevented that air and steam etc. are penetrated in equipment, thereby played the effect of protection equipment.
The material of O RunddichtringO 2 is silicon rubber material, adopts methyl vinyl silicone rubber, has good sealing property, effectively blocks air and steam etc.
Be exactly more than structure and the action effect of a kind of POGO PIN, its advantage: simple and practical, cost is lower; easy to use, when waterproof POGO PIN is electrically connected to equipment, O RunddichtringO is blocks air and steam effectively; reach the effect of sealing, thereby played the effect of protection equipment.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
