Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a connector provided with EMI countermeasures, and more particularly to an EMI countermeasure connector having a lock function. This connector can be used when an input / output connector or the like of a mobile phone is connected as a mating connector. 2. Description of the Related Art Various types of EMI countermeasure connectors have already been proposed. This type of connector includes a connector element for obtaining connection with a mating connector, and a metal shell as a shielding material covering the outer periphery of the connector element. It also typically includes a lock spring for locking the connection of the connector element to the mating connector. FIG. 7 shows an example of a shell 1 and a lock spring 2 used in a conventional EMI countermeasure connector. As can be seen from FIG. 7, the shell 1 and the lock spring 2 are made separately. [0004] For example, Japanese Utility Model Publication No. 6-16403 discloses a connector in which locking portions are integrally connected via flexible pieces extending from a shield plate corresponding to a shell. [0005] In the structure shown in FIG.
Since the lock spring and the shell are separate bodies, the number of parts increases and the cost increases. In addition, it becomes an obstacle to miniaturization of the connector. On the other hand, in the structure disclosed in Japanese Utility Model Publication No. 6-16403, the locking portion is integral with the shell, but is simply extended from the shell in the fitting direction. Only the spring property in the direction approaching and separating from the connector element can be obtained. Therefore, when a force is applied in the vertical direction, that is, in the fitting direction, a load is applied to the locking portion, and there is a problem that the locking portion is easily broken. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an EMI countermeasure connector having a lock function that reduces the number of parts and is not easily damaged. According to the present invention, there is provided a connector element for obtaining a connection with a mating connector, a lock spring for locking the connection of the connector element to the mating connector, An EMI countermeasure connector including a metal shell covering an outer periphery of the connector element, wherein the lock spring has a locking portion for locking with a mating connector near one end in a direction orthogonal to a fitting direction.
And the other end is formed integrally with the shell, and the lock spring is formed continuously from the side wall of the shell and protrudes laterally in the fitting direction with the mating connector. while gently curved so as to form a part by bending Ri folding <br/>, in the vicinity of the other end of the locking spring, said connector and mating direction of the mating connector
The lock is formed by forming a bent portion having a spring property in both directions of approaching and separating from the element, and forming the bent portion to form a convex portion to the side to impart a spring property.
EM spring is characterized by having a button function for releasing the engagement between the locking portion and the mating connector
An I countermeasure connector is obtained. [0010] The lock spring may have a spring property in a direction approaching and separating from the connector element. 1 and 2, an EMI countermeasure connector according to an embodiment of the present invention (hereinafter simply referred to as "connector") will be described. The connector includes a connector element 11 for obtaining connection with a mating connector (not shown), a first shell part 12 for inserting and fixing the connector element 11 at one end thereof, A second shell part 13 combined with the first shell part 12 and a first resin part forming a hood by covering these from outside and being connected to each other with screws or the like.
And second hood parts 14 and 15. A cable (not shown) is connected to the connector element 11 and is drawn out through the space between the first and second shell parts 12 and 13. First and second shell parts 12, 13
Is formed by punching and bending a metal plate, and forms a shell that covers the connector element 11 and the connection portion of the cable to the connector element 11 and electromagnetically shields the connector element 11. Referring also to FIG. 3, the second shell part 1
3 are provided on the opposite side walls 13a, respectively.
A lock spring 16 for locking the connection to the mating connector is integrally formed. The lock spring 16 extends along the second shell component 13 in the fitting direction with the mating connector, and has a locking portion 17 near the extending end for locking with the mating connector. . The locking with the mating connector by the locking portion 17 is the same as in the related art. Further, the other end of the lock spring 16 is integrally connected to the second shell part 13, and in the vicinity thereof,
A bent portion 18 having a spring property is formed at least in a fitting direction with the mating connector. Bent part 18 is formed so as to form the convex portion to the side, thus locking
The spring 16 has a button function for releasing the engagement with the mating connector. That is, when the lever 19 of the first hood component 14 is pinched with a finger or the like and pushed inward, the force is reduced.
The bent part 18 is connected by the spring 16
The locking member 17 is displaced in a direction approaching the data element 11, and the locking with the mating connector by the locking portion 17 is released. It is needless to say that the lock spring 16 also has a spring property in the direction in which the lock spring 16 approaches and separates from the connector element 11, that is, in the lateral direction, as in the related art. Here, the manufacture of the second shell part 13 will be briefly described. First, a metal plate is punched to obtain a developed shape shown in FIG. Then, the folding curves 21 and
A bending process is performed along 2, 23, 24, and the like. Eventually, the lock spring 16 is folded back and extended,
A planar shape as shown in FIG. The obtained second shell part 13 is incorporated in this connector as shown in FIG. In this state,
The second shell component 13 has a displacement allowing portion 27. That is, the displacement permitting portion 27 is in the vertical direction 28 of the locking portion 17.
And displacement in the lateral direction 29 is allowed. FIG. 6 shows a state in which the locking portion 17 is displaced by the distance d1 by a broken line. As a result, even when a force is applied in the vertical direction 28, the load is less likely to concentrate on the locking portion 17 due to the spring property of the lock spring 16 in the vertical direction 28. Therefore, the lock spring 16 is hardly damaged. As described above, according to the EMI countermeasure connector of the present invention, since the lock spring and the shell are integrated, the size can be reduced, and the number of parts can be reduced, thereby reducing the cost. Is also possible. Further, since the lock spring has a resilient property not only in the horizontal direction but also in the vertical direction, even if a certain load is applied in the vertical direction, the load is not concentrated on the locking portion, so that the lock spring is less likely to be broken.
