Abstract
The utility model relates to a small electric connector with the function of cable protection, which comprises a plug. An electrical inserting contact component is arranged at the front in a plug shell; a tail shell, which is used for a cable to penetrate through and for fixing the cable, is arranged at the tail part of the plug shell; the front section of the tail shell matches with and is inserted into the tail section in the plug shell; a circle of annular groove is arranged at the surface of the tail shell of the inserting part; a counter-buckled annular groove is arranged corresponding to the position of the annular groove and on the inner wall surface of the plug shell; a circle of limiting hoop is arranged in the annular space formed by the two annular grooves; and a rotary limiting structure is arranged at the inserting and matching position of the plug shell and the tail shell. The utility model prevents the cable from axial force through the simple limiting hoop, and realizes the peripheral twist. The rotary limiting structure can prevent the endless rotation in the circumference direction and well protect the cable.
Description
Technical field
The utility model relates to a kind of electric connector, relates in particular to a kind of small-sized electrical connector with cable protection function, belongs to the electroporation field.
Background technology
Electric connector in most cases is used for the transmission of the signal of telecommunication, and the heart yearn of cable should axially not stress in the design, and should reverse on the circumferencial direction, but can not rotate more, otherwise, can injure cable.This requirement for the bigger electric connector of volume, realizes easily.But for small-sized electrical connector, it is not too easy to implement, and has to increase volume sometimes and reaches designing requirement.
The utility model content
Task of the present utility model provides a kind of small-sized electrical connector with cable protection function, with simple structure, realizes the reliable and secure connection of cable.
For finishing above-mentioned task; the technical solution of the utility model is to have adopted a kind of small-sized electrical connector with cable protection function; comprise plug; front portion in the plug casing is provided with electric plug contact; the afterbody of plug casing is provided with and is used for the afterbody housing that passes and fix with cable; it is characterized in that; the leading portion of afterbody housing coincide and is inserted into the interior rear of plug casing; afterbody surface of shell in the Plug Division is provided with a ring annular groove; be provided with the cannelure of make-up with the internal face of the plug casing of this cannelure corresponding position; in the annular space that above-mentioned two cannelure make-ups form, be provided with a circle position-limited hoop, be provided with the rotary stopper structure at plug casing and afterbody housing grafting matching part.
The cannelure of plug casing is provided with one section radially slotted hole that is used for interspersed described position-limited hoop.
Surface before the cannelure of afterbody housing is provided with the sealing ring that cooperates with the internal face of plug casing.
Be provided with the annular space of the rectangular interfaces of mutual fastening formation at the afterbody of plug casing and afterbody housing grafting matching part, be fixed with an axial pin on the annular end face of the plug casing in this space, be fixed with a pin radially on the periphery of the afterbody housing in this space, the spacing cooperation of two pins constitutes the rotary stopper structure.
The rear of afterbody housing is the body that a section surface has retaining sour jujube ring structure.
Because the afterbody surface of shell in the Plug Division is provided with a ring annular groove; be provided with the cannelure of make-up with the internal face of the plug casing of this cannelure corresponding position; the cannelure of plug casing is provided with one section radially slotted hole; in the annular space that above-mentioned two cannelure make-ups form, be provided with a circle position-limited hoop; be provided with the rotary stopper structure at plug casing and afterbody housing grafting matching part; thereby; the utility model adopts simple position-limited hoop both to avoid the cable axially loaded; realized circumferential twisting again; and the rotary stopper structure has been avoided the rotation of having no limits of circumferencial direction, has well played the protective effect to cable.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
