Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a connector mounting device to be mounted on a plate-like member such as a printed circuit board and an electric connector having such a mounting device.

[Conventional technology]

A large number of printed circuit boards (or circuit boards) are widely used as electric or electronic devices become more multifunctional and systematized, and are used for connection between printed circuit boards or between printed circuit boards and other electronic / electric devices. 2. Description of the Related Art Electrical connectors that can be mounted on a computer have become widespread.

In order to attach such a connector to a plate-like member, bolts and nuts can be used, but it takes a long time to attach and detach the connector and requires a relatively large space, which is not suitable for recent small connectors. Therefore, various types of connector mounting devices that are small and easily mounted on a plate-like member have been proposed.

Examples of conventional connector mounting devices are disclosed in Japanese Utility Model Publication No. 1-26454 and Japanese Utility Model Publication No. 2-37744. The features of these are shown in FIGS. 4 (A) and (B),
This will be briefly described below. The connector mounting device 1 shown in FIG. 1A includes a base 5 having a substantially rectangular plate shape, a space or opening 3 near the top, and a pair of legs 7 extending below the base 5. I have. The legs 7 are flush with the base 5. A pair of legs
7, 7 are substantially parallel to each other and have locking projections (barbs) on the outer surface
Has 6,6. Similarly, the base 5 has outer protrusions 4 on both sides. The mounting device 1 is press-fitted into slots 12 formed at both ends of the housing of the connector 10, for example. Due to this press-fitting, the mounting device 1 causes the inner projections 4
4 is engaged, and the legs 7, 7 are fixed in a state protruding from the bottom surface of the housing. A connector having such a mounting device 1 is inserted into an opening of a plate-shaped member, for example, a through hole of a printed circuit board. Since the legs 7, 7 have elasticity, the legs 7, 7 are biased in a direction approaching each other within the opening, and the locking projections are provided.
6 and 6 bite into the inner wall of the opening to easily and securely fix the connector to the plate-like member.

The connector mounting device 20 of FIG. 4B is also formed by processing a metal plate, and has a base 22 having an expanded top 21, a pair of legs 24 extending downward from the base, and formed near the tip thereof. And a locking portion 25 protruding outward. The base 22 has outer protrusions 26 on both sides. Such a mounting device 20 is press-fitted into a slot of the connector housing 27, and is a plate-like member such as a printed board.
Insert in alignment with opening 29 of 28. As a result, legs 24
Due to the elasticity of the connector housing 27, the connector housing 27 can be attached to the plate member.

[Problems to be solved by the present invention]

However, all of the above-described conventional connector mounting devices are generally flat and utilize the elasticity of a pair of separated legs inward (toward the mating leg). Therefore, sufficient elasticity cannot be obtained, and there are drawbacks such as an excessively large press-in force and an excessively small holding force due to variations in the dimensions of the plate member. In particular, when inserted into a plated through hole of a printed board, there is a great risk that the plating layer will be destroyed.

Accordingly, it is an object of the present invention to provide a connector mounting device having a large elasticity, a low insertion force and a sufficient holding force, and having a tolerance for a dimensional change of an opening, and an electric connector having such a mounting device. I do.

[Means for solving the problem]

A connector mounting device according to the present invention includes a base inserted into and held in a slot of a connector housing, and a leg including two holding legs extending from the base, and is formed of one elastic metal plate. Is done. The legs are formed of a metal plate that is elongated in the longitudinal direction. The leg has an elongated slot in the longitudinal direction, the tip is separated by a slit, and the two holding legs are bent in a substantially "C" shape in opposite directions in the thickness direction of the metal plate. To form The base has a cantilevered lance.

The connector of the present invention has a slot formed on the mounting surface of the housing, press-fits the base of the mounting device to the connector main body, holds the connector on the connector main body, and extends the leg portion out of the connector main body. The connector body can be attached to the member. Preferably, the mounting device is press-fitted and held at least near both ends in the longitudinal direction of the connector body.

〔Example〕

Hereinafter, an embodiment of a connector mounting device of the present invention and a connector using the same will be described in detail with reference to the accompanying drawings.

1 (A) and 1 (B) are a front view and a side view, respectively, of a preferred embodiment of a connector mounting device according to the present invention. As is apparent from the figure, the connector mounting device of the present invention is manufactured by punching a brass plate having a thickness of, for example, 0.3 mm. Preferably, the surface is plated with nickel and solder.

The connector mounting device 30 of the present invention includes a substantially rectangular base 40 and legs 50 extending from the base. A plurality of barbs 42 and 44 are formed on the side edges of the base 40, and a cantilever lance 48 is formed at the center by a concave groove 46. It will be understood from FIG. 1B that the upper end of the lance 48 is fixed to the base 40 in the figure and the whole is bent at an acute angle from the plane. As a result, when the mounting device 40 is pressed into the slot of the connector housing from the top, the barbs 42 and 44 on the side edge bite into the end wall of the slot, and the lance 48 bites into one side wall surface of the slot to securely insert into the housing. Fixed to The concave groove 46 gives the base 40 a slight elasticity.

Next, the leg 50 has a pair of flexible retaining legs 52, 54 having an elongated slot 51 in the center, as seen from FIG. 1A when viewed from the front. The distal ends 56 of the holding legs 52 and 54 face each other, and come into contact with each other through the slit 58 under a normal state. As is apparent from FIG. 1B, the pair of holding legs 52, 54 are bent substantially in the shape of "" at the upper and lower ends and at the center in opposite directions in the thickness direction of the base 40. Both holding legs 52, 54
Has a maximum bending width W of about 2.1 mm in the preferred embodiment.

FIG. 2 is an explanatory view when the connector mounting device 30 of FIG. 1 is inserted into an opening 60 of a plate-like member such as a printed board. FIG. 5A shows the dimensional relationship between the holding legs 52 and 54 and the opening 60 before the mounting device 30 is inserted into the opening 60. It can be seen that the outer ends of the legs 52, 54 project out of the opening 60. However, the mounting device 30
Is press-fitted, as shown in FIG.
The slit 58 is deviated to the opposite side along the inner surface of the opening 60 so that the slits 58 are separated from each other and fits in the opening 60. This press-fitting is performed relatively smoothly by the tapered portions 52a, 54a below the holding legs 52, 54. It will be understood that the inner wall surface of the opening 60 is pressed with sufficient pressure by the repulsive force of the elasticity of the holding legs 52, 54.

FIG. 3 shows an example of the connector 70 using the mounting device 30 of the present invention described above. FIGS. 7A, 7B and 7C are a front view, a side view and a bottom view of the connector 70, respectively. As can be seen from this figure, this particular embodiment has three terminals 72 arranged as an example and a pair of mounting devices 74, 74 arranged at substantially both ends of the terminal row. The mounting device 74 is press-fitted and held in a slot 76 (see FIG. 3C) formed on the bottom surface of the housing of the connector 70. The mounting device 74 can be integrally molded with the connector housing.

The preferred embodiments of the connector mounting device and the connector using the same according to the present invention have been described above. However, it should be understood by those skilled in the art that the present invention should not be limited to only such an embodiment, and various modifications can be made without departing from the necessity. For example, barbs 4 on both sides of the base 40
2, 44 is not required. Further, one or more lances 48 may be formed on each surface of the base 40.

[Effect of the invention]

The connector mounting device of the present invention is formed integrally from a metal plate, and a pair of holding legs are bent in the thickness direction in a substantially "<" shape with respect to the base surface. Therefore, the insertion force of the plate-shaped member into the opening is low and smooth, and it is possible to cope with a relatively wide range of opening dimensions. The possibility of damaging the plating layer on the inner surface of the opening can be eliminated.

Further, according to the electrical connector of the present invention, since the above-described mounting device is used, the electrical connector can be easily mounted in a through hole of a printed board and can be reduced in size. Therefore, it is very suitable for a connector for a small high-density mounting type electronic device.
