DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector locking mechanism, and more particularly, to a locking mechanism for a SIMM connector which is mounted on an electronic circuit board by soldering and is suitable for use in connecting electronic circuits.

[0002]

2. Description of the Related Art Conventionally, a lock mechanism for holding a module board of a SIMM connector uses a metal plate or an insulative PVC mold, and the lock mechanism for a metal plate is applied to a SIMM connector molded by a PVC mold. A metal plate component was newly incorporated to form a lock mechanism. Such a conventional example is disclosed in, for example, JP-A-04-2825.
81 and JP-A-03-216973.

[0003] The lock mechanism of the PVC mold of one insulator has been formed of the same material as the SIMM connector body.

[0004]

However, in the above-described prior art, the locking mechanism of the metal plate has no problem in holding the module substrate, but is expensive because the metal plate is used as an individual component. There were drawbacks.

[0005] One PVC molded SIMM
The lock mechanism of the connector is inexpensive compared to the lock mechanism of the metal plate, but the lock part is cut off at the edge of the side of the module board by repeated mounting of the module board,
A lock failure that could not be mounted on the module board occurred.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional circumstances, and accordingly, an object of the present invention is to provide a novel connector lock mechanism which can solve the above-mentioned problems inherent in the prior art. It is in.

[0007]

In order to achieve the above object, a connector lock mechanism formed by a PVC mold according to the present invention is provided with a projection below a lock mechanism section 1a in contact with an edge section 2a of a module substrate 2. A portion 1b is provided.
A series of operations when the module substrate 2 is mounted on the SIMM connector 1 will be described. FIG. 2A is a plan view of the module substrate 2 when initially mounted, FIG. 2B is a cross-sectional view thereof, and FIG. 4) is a plan view showing a state where the module substrate 2 is in contact with the protruding portion 1b, FIG.
4A is a plan view showing a state after the module board 2 is mounted, and FIG. 4B is a sectional view thereof.

2 (a) and 2 (b) to FIG. 3 (a),
In the mounting operation of the module substrate 2 shown in FIG. 3B, the locking mechanism 1a is pushed and expanded by the projection 1b first contacting the edge 2a of the module substrate 2 (FIG. 3).
(States (a) and (b)), and the module board 2 as shown in FIGS. 4A and 4B can be mounted while maintaining a state not in contact with the edge portion 2a. FIG. 4 in this case
(A) is the same as the state of FIG. 1 (b), and a cross section is added in FIG. 4 (b). This has a structure that can prevent the edge portion 2a of the module substrate 2 that is conventionally generated from being cut off.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will now be described with reference to FIGS.
(B), FIG. 2 (a), FIG. 2 (b), FIG. 3 (a), FIG.
(B), FIG. 4 (a) and FIG. 4 (b).

A SIMM connector 1 formed by the PVC mold of the present invention shown in FIG.
The protrusion 1b that comes in contact with the side surface 2a of the lock mechanism 1a is provided below the lock mechanism 1a.

A series of operations when the module substrate 2 is mounted will be described. FIG.
(A), in the operation of FIG. 2 (b), when the protrusion 1b first comes into contact with the edge 2a on the side surface of the module substrate 2, the lock mechanism 1a is pushed and expanded (FIG. 3).
(A), the state of FIG. 3 (b)). That is, the protrusion 1b formed integrally with the SIMM connector 1 receives a force directed outward in a direction substantially perpendicular to the traveling direction when the module board 2 is mounted on the SIMM connector 1 from the edge 2a of the module board 2. Similarly, the lock mechanism 1a formed on one side of the SIMM connector 1 is slightly displaced outward in a direction substantially perpendicular to the traveling direction, that is, is pushed outward. By this operation, the module board 2 can be accurately mounted at a predetermined position of the SIMM connector 1 as shown in FIGS. 4 (a) and 4 (b) while maintaining a state of not contacting the edge portion 2a. it can.

In the conventional example shown in FIGS. 5, 6 (a) and 6 (b), in a series of operations for mounting the module board 2 as described above, the PVC lock mechanism 3a is used.
Is removed, so that the module substrate 2 cannot be held after repeated mounting. This disadvantage is solved by the above configuration of the present invention.

In the conventional metal plate lock mechanism 4a formed of a metal plate as an individual component shown in FIG. 7, there is no problem in holding the module substrate by repeated mounting.

[0014]

As described above, in the lock mechanism formed by the PVC mold of the present invention, the lock mechanism is pushed and expanded by the projection first contacting the edge of the side surface of the module substrate. Of the lock mechanism is prevented. Thereby, it can be used as an inexpensive SIMM connector that prevents a lock failure.
