Description

Quick plug-in connector

Technical Field

The utility model belongs to the technical field of the electric connector, in particular to quick plug-in connector.

Background

Electrical connectors are devices used to transmit signals and electrical current between circuits and equipment. The signal, power supply and optical circuit can be connected and disconnected quickly and easily, and the circuit has reliable performance in various severe environment application occasions.

The quick plugging and unplugging of the connector has the characteristics of small use space, convenient installation, no need of tools and quick disconnection or connection establishment, and is an important characterization in the characteristics of the connector.

In the prior art, some direct locking canceling structures are connected through close fit of a plug, a socket contact and a contact sleeve, but the connector of the structure has no shock resistance, and risks exist in safety and reliability. Some utilize the buckle to realize the quick plug of connector, have the structure complicacy, occupy bulky, with high costs, can not the quick switch over user state's shortcoming.

Disclosure of Invention

The utility model aims at overcoming the defect that prior art exists, providing a convenient to use, the shock resistance is good, but quick plug, fast switch over user state's high security, the quick plug-in connector of reliability.

Realize the utility model discloses the technical scheme of purpose is: a quick plug-in connector is provided with a socket and a plug matched with the socket; a sheath and a contact conductor are arranged in the socket, and a self-tightening spiral spring ring capable of radially and elastically deforming is mounted on the inner wall of the shell of the socket; the contact conductor is arranged between the sheath and the shell; an insulating part is arranged between the sheath and the rear seat of the socket; the plug is provided with an annular groove, the plug is matched with the sheath in the radial direction, and the annular groove at the plugging position corresponds to the position of the self-tightening spiral spring ring.

According to the technical scheme, the self-tightening spiral spring ring is arranged on the inner wall of the socket and is provided with the annular groove.

According to the technical scheme, the self-tightening spiral spring ring is a 360-degree closed body.

In the technical scheme, the end part of the plug is conical.

According to the technical scheme, a sealing element is arranged between the inner wall of the socket and the sheath.

According to the technical scheme, a sealing ring is connected between the contact conductor and the shell.

According to the technical scheme, the rear seat of the socket is in threaded connection with the shell.

After the technical scheme is adopted, the utility model discloses following positive effect has:

(1) the utility model discloses utilize the spring coil to form reliable connection in quick plug, because spring coil circumference clamping-force distributes evenly and fatigue strength is high, more can guarantee electric connector's shock resistance and security, electric connector when throw off as long as extract the plug from the socket can, installation and unblock are all very convenient, and can effectively reduce the connector volume.

(2) The utility model discloses can carry out the blind plugging, simple structure, convenient to use, spare part is with low costs, has very high value in convenience, reliability, security.

(3) The utility model discloses a tip of plug is the toper, is convenient for blind insertion.

Drawings

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is given in conjunction with the accompanying drawings, in which

Fig. 1 is a schematic structural diagram of the plug of the present invention;

fig. 2 is a schematic structural diagram of the socket of the present invention;

fig. 3 is a right side view of the socket of the present invention;

fig. 4 is a sectional view of the present invention.

Detailed Description

(example 1)

Referring to fig. 1 to 4, the present invention has a socket 2 and a plug 1 mating with the socket 2; a sheath 22 and a contact conductor 23 are arranged inside the socket 2, and a self-tightening spiral spring ring 21 which can elastically deform in the radial direction is arranged on the inner wall of a shell 24 of the socket 2; the contact conductor 23 is arranged between the sheath 22 and the housing 24; an insulating part 26 is arranged between the sheath 22 and a rear seat 25 of the socket 2; the plug 1 is provided with an annular groove 11, the plug 1 is matched with the sheath 22 in the radial direction, and the annular groove 11 at the plugging position corresponds to the position of the self-tightening spiral spring ring 21. The self-tightening spiral spring ring 21 is arranged on the inner wall of the socket 2 and provided with an annular groove 27. The self-tightening helical spring ring 21 is a 360 deg. closure.

The end of the plug 1 is tapered. A seal 28 is provided between the inner wall of the socket 2 and the sheath 22. A sealing ring 29 is connected between the contact conductor 23 and the housing 24. The rear seat 25 of the socket 2 is screwed to the housing 24.

The utility model discloses a theory of operation does: socket 2 and plug 1 are respectively on different equipment, carry out butt joint (blind cooperation) with socket 2 and plug 1 through external force, and the tip of plug 1 is the toper to guide plug 1 to get into socket 2 alignment center, when plug 1 pushed socket 2, spring coil 21 in the sheath 22 takes place elastic deformation, forms closely to cooperate the completion when spring coil 21 slips into the annular 11 of plug 1 promptly and matches with plug 1. When the plug 1 is pulled out of the socket 2, the spring ring 21 changes the inner diameter during the processes of inserting and separating the male connector and the female connector and forms connector matching locking.

The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
