Description

Longer and corrosion-resistant pinhole for connector of life

Technical Field

The utility model relates to the technical field of connectors, in particular to a pinhole for a connector, which has longer service life and corrosion resistance.

Background

Connectors are well known to electrically connect and signal transfer between devices, assemblies and components, systems and systems, and are essential elements that make up a complete system.

However, in use, the existing connector finds that the pin hole of the traditional connector plug has a certain defect, the service life of the plug is basically 100-200 times, then serious fatigue deformation can easily occur, the clamping force is seriously reduced, the reliable connection of the pin hole and the pin is affected, virtual connection is easily occurred, if the existing pin hole is used in a humid environment for a long time, water vapor enters the interior of the pin hole, rust is easily caused between the pin hole and the pin, and the pin hole cannot be used continuously or is difficult to use again.

Disclosure of Invention

(one) solving the technical problems

Aiming at the defects of the prior art, the utility model provides a pinhole for a connector, which has good plugging resistance and good corrosion resistance, and has longer service life and good corrosion resistance.

(II) technical scheme

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a longer and for corrosion-resistant connector pinhole of life, includes the installation piece, the left end of installation piece is provided with the wiring pipe, the top right-hand member of wiring pipe is provided with the fluting, the right-hand member of installation piece is provided with the intubate, the inside of intubate is provided with two clamping pieces that set up relatively, every the clamping piece is the bulge form, upper and lower two the middle part of clamping piece upwards respectively with undercut to form circular-arc recess, the right-hand member of intubate is provided with the baffle ring, install sealed pad between baffle ring and the right-hand member of intubate.

Further, the sealing gasket is a circular sealing gasket.

Still further, the right end of the cannula extends inwardly in a necked-in shape, and the minimum diameter of the stop ring is the same as the minimum diameter of the right end of the cannula.

Preferably, the outer package of intubate is provided with a layer anticorrosive coating.

(III) beneficial effects

Compared with the prior art, the utility model provides the pinhole for the connector, which has longer service life and corrosion resistance, and has the following beneficial effects:

this life is longer and corrosion-resistant connector is with pinhole to receive the row extrusion force of contact pin through two clamping pieces to upwards respectively with crooked downwards, under the elasticity and the toughness of clamping piece, press from both sides tight contact pin have between clamping piece and the contact pin, compare in present pinhole, greatly increased the life of pinhole, through the minimum diameter of sealing gasket than the maximum diameter of contact pin little, make sealing gasket can overlap on the contact pin, thereby make the inside that this pinhole can be good isolation steam gets into the pinhole, make this pinhole have good corrosion resistance.

Drawings

FIG. 1 is a schematic diagram of the structure of the present utility model;

fig. 2 is a schematic view of a partial right-hand structure of the present utility model.

In the figure: 1. a mounting block; 2. a wire connection tube; 3. slotting; 4. a cannula; 5. a clamping piece; 6. a baffle ring; 7. a sealing gasket; 8. and an anti-corrosion layer.

Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-2, a pinhole for a corrosion-resistant connector with longer service life of the present utility model includes a mounting block 1 for mounting, a wire receiving tube 2 is disposed at the left end of the mounting block 1, a slot 3 is disposed at the right end of the wire receiving tube 2 for receiving electricity, a cannula 4 is disposed at the right end of the mounting block 1, the wire receiving tube 2 and the cannula 4 are made of metal materials, so that the electrical conduction in the cannula 4 is conducted onto the wire receiving tube 2, and preferably made of copper, two oppositely disposed clips 5 are disposed inside the cannula 4, preferably made of copper, each clip 5 is in a bulge shape, the middle parts of the upper and lower clips 5 are respectively recessed upward and downward to form an arc-shaped groove, after the plug is inserted, the plug is tightly connected with the groove, a baffle ring 6 is disposed at the right end of the cannula 4, a sealing pad 7 is disposed between the baffle ring 6 and the right end of the cannula 4, the sealing pad 7 is made of a circular sealing pad 7, and has better sealing property, and simultaneously, the right end of the cannula 4 is not obstructed by plugging of a plug needle, the right end of the cannula 4 is in a bulge-shaped shape, and the diameter of the minimum collar 6 is not obstructed by the right end 8 of the cannula 4, and the right end of the cannula 4 is prevented from corroding by an inner layer, which is wrapped by the least outer layer 8.

In summary, the pin hole for the connector with longer service life and corrosion resistance has the working principle that when the pin is inserted into the pin hole, the two clamping pieces 5 are subjected to the row extrusion force of the pin, so that the two clamping pieces 5 are respectively bent upwards and downwards, the pin is clamped under the elasticity and toughness of the clamping pieces 5, the clamping pieces 5 are tightly connected with the pin, the pin hole hot plug times are more than 500 times according to experiments, the service life of the pin hole is greatly prolonged, and after the pin hole is inserted into the pin hole, the sealing gasket 7 can be sleeved on the pin hole due to the fact that the minimum diameter of the sealing gasket 7 is smaller than the maximum diameter of the pin hole, however, the sealing gasket 7 can be prevented from being separated from the pin hole due to the blocking effect of the needle tube and the blocking ring 6.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
