Description

  The present invention relates to a shielded connector connected to a shielded cable such as a shielded twisted pair electric wire or a coaxial cable.

  In general, a twisted pair electric wire called STP (Shield Twisted Pair), which has two signal lines twisted together, is used inside a shield conductor. The feature is that the influence of electromagnetic induction can be reduced by reversing the direction of the magnetic field generated by the adjacent wire loops formed by this twisted twist and canceling each other's generated magnetic field. In this case, it is known that the outer side is further covered with a shield conductor, so that it is difficult to radiate electromagnetic induction noise to the outside and it is difficult to receive noise from the outside, and it is widely used as a LAN cable for high-speed transmission.

  Usually, such shielded twisted-pair electric wires are processed by terminal processing and connected to a dedicated connector called a modular connector. Recently, electric devices mounted on automobiles such as car navigation systems have been used with such shielded twisted-pair electric wires. May constitute an in-vehicle network.

  As a shield connector connected to the terminal part of this shield twisted pair electric wire, there exists a thing of the composition indicated by the following patent documents 1, 2, for example.

  The shield shell provided in the shield connector disclosed in Patent Document 1 is composed of a shield case and a shield cover, and the shield cover has an opening of the shield case used when accommodating and holding an inner housing that accommodates a plurality of terminals. It is supposed to close. Moreover, such a shield shell is inserted from the rear opening part of the outer housing disclosed by patent document 2, and is accommodated and held in the shell accommodating chamber of the outer housing.

  Such a shield shell is provided with a pair of projecting pieces cut and raised outward from the outer surface of the shield shell as a structure that realizes a function of stopping and preventing the shield shell from being stopped in the shell housing chamber of the outer housing. And a locked portion in which an opening is formed in association with the cut and raised formation of the pair of protruding pieces.

  In addition, the shell housing chamber of the outer housing is brought into contact with the front end of the protruding piece of the locked portion of the shield shell and stopped in front, and can be bent and deformed in the height direction, and after being bent and deformed, it is restored. A lance that locks the front end of the opening of the locked portion of the shield shell and prevents the shield shell from coming off is provided. In this case, the rear end of the lance is cantilevered in the shell housing chamber, and the front end can be bent and deformed.

That.
In order to solve the above-described problem, another invention is a shield connector in which a shield shell covering the outer periphery of an inner housing that accommodates terminals is inserted and retained from the rear opening of the outer housing, In the shell housing chamber of the housing, there are provided a stopper for stopping the shield shell in front, and a lance that can be bent and deformed in the height direction and once returned after being bent and deformed to prevent the shield shell from coming off. The outer surface of the shield shell is formed with a locked portion in which a portion of the outer surface protrudes outward so that portions other than the front edge and the rear edge are not cut, and the front edge of the locked portion is The gist of the invention is that the stopper is brought into contact with the stopper and stopped at the same time, and the rear end edge of the locked portion is locked by the lance to be prevented from coming off. Than is.
In order to solve the above-described problem, another invention is a shield connector in which a shield shell covering the outer periphery of an inner housing that accommodates terminals is inserted and retained from the rear opening of the outer housing, In the shell housing chamber of the housing, there are provided a stopper for stopping the shield shell in front, and a lance that can be bent and deformed in the height direction and once returned after being bent and deformed to prevent the shield shell from coming off. On the outer surface of the shield shell, there is formed a locked portion in which a part of the outer surface protrudes outward so as to have an arch shape supported at both ends in the width direction, and the front end edge of the locked portion is The gist is that the front end is stopped by contacting the stopper, and the rear end edge of the locked portion is locked by the lance to be prevented from coming off.

  In this case, the front end edge 10b and the rear end edge 10d of the locked portion 10 of the shield shell 5 are respectively formed with cut surfaces 10c and 10e cut and raised in a trapezoidal shape, and the front end edge 10b The cut surface 10c of the outer housing 8 is brought into contact with the stopper 12 and stopped at the front, and the cut surface 10e of the rear edge 10d is locked by the locking portion 11d of the lance 11 to prevent the outer housing 8 from being removed. The shield shell 5 is firmly stopped and prevented from coming off in the storage chamber 8c.

  In addition, a tapered guide surface 10f that bends and deforms the lance 11 when the shield shell 5 is inserted into the shell housing chamber 8c of the after housing 8 is provided at the front end edge 10b of the locked portion 10 of the shield shell 5. Therefore, there is little catching when inserting the shield shell 5 into the shell accommodating chamber 8c, and such insertion is facilitated and workability is improved.

  As mentioned above, although the embodiment of the shield connector concerning the present invention was described, the present invention is not limited to such an embodiment at all, and can be implemented in various modes without departing from the gist of the present invention. Of course. For example, in the above-described embodiment, the trapped portion 10 of the shield shell 5 is configured to be trapped in a trapezoidal shape. However, the locked portion 10 by knocking out is limited to such a shape. Instead, various shapes can be applied.
