Embodiment Construction

[0015] Embodiment 1 of the small tensile electrical connector of the present invention, such as Figure 1-3 As shown, there is a cylindrical metal shell 1 as a whole, and the metal shell 1 can play a certain shielding effect; the metal shell 1 is provided with a connecting nut 2 along the axial direction, and the connecting nut 2 is connected to the The metal shell 1 is rotated and fitted, and the metal shell 1 is provided with a contact module. The contact module is composed of an insulator 3 and a contact 4 assembled on the insulator 3; the tail end of the metal shell 1 is provided with a tail cable. The cable is composed of a wire 5, a shielded wire 6 and an outer sheath 7. The wire 5 of the tail cable is connected to the corresponding contact piece, and its front end extends into the metal shell 1. The part of the tail cable located in the metal shell 1 is covered with a fixed 8, the fixed sleeve 8 adopts a C-shaped metal sleeve, and the fixed sleeve 8 is compressed on the...

Abstract

The invention relates to a small-sized anti-pull electric connector which comprises a cylindrical metal shell and a tail cable arranged at the tail end of the metal shell, wherein a C-shaped fixed sleeve is sleeved on a part of the tail cable inside the metal shell, the fixed sleeve is tightly bound on the outer skin of the tail cable to be in anti-jumping fit with the tail cable along the axial direction, and an inwards-turned edge in stop fit with the rear end of the fixed sleeve is arranged at the tail end of the metal shell; when the tail cable is pulled, the tail cable is prevented from being pulled out or disconnected from a corresponding contact element by the stop fit of the fixed sleeve and the metal shell, moreover, the fixed sleeve is fixed on the outer skin of the tail cable, therefore, the holding force for preventing the tail cable from being pulled relative to the metal shell is finally acted between the outer skin of the tail cable and the metal shell, so that the situation that the electric connector is pulled to be damaged is avoided, and the problem that the anti-pull performance of an existing round small-sized electric connector is poor is solved.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a small tensile electrical connector. Background technique [0002] A circular small electrical connector can be seen on the market, which includes a cylindrical metal shell, a contact piece arranged in the metal shell through an insulator, and a tail at the rear end of the metal shell. The cable requires an outer diameter of less than 7mm and a length of less than 16mm (not including the length of the tail cable). The internal space of the product is limited, and the traditional tensile, torsion-resistant and shielding structures cannot be used. Therefore, the above-mentioned structures currently on the market Most of the connectors have no tensile, torsion and shielding functions or have limited tensile and torsional performance. However, when in use, the tail cable of the connector is often subjected to tension, torsion, and is bent at a large angle, which is very easy to...
