Abstract

The utility model discloses a watertight connector. The connector comprises a plug and a socket. The socket comprises a socket case in which a pin is installed through a pin insulation base. The plug comprises a plug case. A plug hole insulation base is arranged inside the front end of the plug case. A plug hole is arranged in the plug hole insulation base. A wire clamp with an insulation sleeve on the inner side is arranged on the back end of the plug hole insulation base. A wire-clamping sleeve is arranged on the back end of the wire clamp. A connection nut is arranged on the periphery of the front end of the plug case. A protective sleeve is arranged on the periphery of the back end of the plug case. The front end of the protective sleeve is limited on a limit step. A cable sleeve is arranged between the protective sleeve and the plug case. A sealing plug and a hold-down ring are arranged between the back end of the wire-clamping sleeve and the end face of the inner cavity of the cable sleeve. Good sealing performance is achieved through cooperation of a plurality of components in the connector. The connector achieves simple structure, good sealing effects and stable and reliable performance, and is suitable for applications which require waterproof sealing.

Description

Watertight connector

Technical field

The utility model relates to a kind of for the watertight connector that connects signal cable, belongs to technical field of electric connectors.

Background technology

In all kinds of electronic systems, usually need with electric connector two parts to be connected; realize the transmission of signal; existing electric connector application scenario is extensive; for some when the wet application scenario of water is received by regular meeting; then need electric connector to have the waterproof sealing function, to guarantee that system works is normal.Yet existing electric connector is unreasonable owing to structure arranges, and water-tight is poor, does not reach good sealing effectiveness, therefore usually can make seepage to electric connector inside, causes the damage of electric connector, has influenced the normal use of electric connector.

Summary of the invention

It is good that the technical problems to be solved in the utility model provides a kind of water-tight, can guarantee connector long-term normal watertight connector that uses under the water wet environment.

In order to solve the problems of the technologies described above, watertight connector of the present utility model comprises plug and socket, and socket comprises the Socket casing that can be connected with external component, is provided with the contact pin of installing by the contact pin insulating base in the Socket casing; Plug comprises a plug casing, be provided with the jack insulating base in the end of plug casing front end, be provided with the jack that cooperates with contact pin in the jack insulating base, the rear end of jack insulating base is provided with the wire clamp that an inboard has insulating case, and the rear end of wire clamp is provided with a clamp cover; The outer periphery of plug casing front end is equipped with an attaching nut that can be connected with Socket casing, is provided with seal groove simultaneously between plug casing and the attaching nut and between plug casing and the jack insulating base, is provided with sealing ring in the seal groove; The outer periphery of plug casing rear end is equipped with a sheath that plays protective action, the front end of sheath is spacing on a limited step, be provided with a cable cover between sheath and the plug casing, be provided with a sealing tamponade and a hold-down ring between the interior resonator end surface of clamp cover end, rear end and cable cover.

Between described sealing tamponade and the hold-down ring and between sealing tamponade and the clamp cover compressive plane that is oppositely arranged is arranged, described compressive plane is the arch to sealing tamponade umbo.

After adopting above-mentioned structure, because the plug and socket with insulating base structure, the rear end of jack insulating base also is provided with the wire clamp that an inboard has insulating case, the sealing tamponade and the hold-down ring that arrange between the clamp cover that arranges by the wire clamp rear end and the interior resonator end surface of cable cover cooperatively interact, cooperatively interact by multiarticulate thus, reached good seal request, the while structure arranges simply, sealing effectiveness is good, stable and reliable for performance, be applicable to the application scenario with waterproof sealing requirement.

Embodiment

Below in conjunction with the drawings and specific embodiments, watertight connector of the present utility model is described in further detail.

As shown in the figure, watertight connector of the present utility model comprises plug and socket, and socket comprises the Socket casing 1 that can be connected with external component, is provided with the contact pin of installing by contact pin insulating base 23 in the Socket casing 1; Plug comprises a plug casing 4, be provided with jack insulating base 5 in the end of plug casing 4 front ends, be provided with the jack 6 that cooperates with contact pin in the jack insulating base 5, the rear end of jack insulating base 5 is provided with the wire clamp 10 that an inboard has insulating case 9, and the rear end of wire clamp 10 is provided with a clamp cover 11; The outer periphery of plug casing 4 front ends is equipped with an attaching nut 7 that can be connected with Socket casing 1, is provided with seal groove simultaneously between plug casing 4 and the attaching nut 7 and between plug casing 4 and the jack insulating base 5, is provided with sealing ring in the seal groove; The outer periphery of plug casing 4 rear ends is equipped with a sheath 8 that plays protective action, the front end of sheath 8 is spacing on a limited step, be provided with a cable cover 12 between sheath 8 and the plug casing 4, be provided with a sealing tamponade 13 and a hold-down ring 14 between the interior resonator end surface of clamp cover end, rear end and cable cover 12, in the time of need carrying out the cable connection, cable can be passed in the endoporus of sheath 8, at this moment, the endoporus of cable and sheath 8 closely cooperates water can not be entered in the sheath.

Further can also between sealing tamponade 13 and the hold-down ring 14 and sealing tamponade 13 and clamp the relative compressive plane that pushes is set between overlapping 11, compressive plane is the arch to sealing tamponade 13 umbos, thus can be by crush seal tamponade 13, make expanding to plug casing 4 inside and outside both sides of sealing tamponade 13, optimized the reliability of sealing effectiveness and connection more.
