Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an electrical connector consisting of a female connector and a male connector that fits into the female connector.

[Background of the idea]

FIG. 2 shows a conventional electrical connector of this kind, which uses a flexible printed board 1 and includes an instrument housing case 2 in which instruments (not shown) are housed, and an instrument housing case 2 in which instruments (not shown) are housed. An electrical connector 5 has a male connector 4 fitted to a female connector 3 provided in a case 2, and a connector housing 7 of the male connector 4 is provided in the female connector 3 provided in the instrument housing case 2. A locking hole 8 is provided which can be locked with a locking claw 10 provided on an integrally provided elastic lever (lock arm) 9, and the male connector 4 is completely fitted into the female connector 3. At this time, the locking pawl 10 is locked in the locking hole 8, and both connectors 3 and 4 are held together. Note that 6 is a wire bundle, 11 is a grip provided at the tip of the elastic lever 9, 12 is a female connector, and 13 is a male connector that comes into contact with the female connector 12. However, in the case of such an electrical connector 5, when parts such as screws are dropped into the interior of the instrument housing case 2 through the locking hole 8 provided in the instrument housing case 2 during instrument assembly work, This component has disadvantages such as generating abnormal noise due to vibration, etc., and short-circuiting an electric circuit when this component is a conductor. In order to eliminate this drawback, for example, as shown in Fig. 3, a narrow locking hole 8' is provided in the female connector 3 to prevent the parts from falling in, or a locking hole 8' as shown in Fig. 4 is provided in the female connector 3. It has been considered to provide a cover 14 that covers the back side of the hole 8 integrally with the case 2, but in the conventional example shown in FIG. 3, since the locking hole 8' is narrow, the lock arm 9 is also narrow. This causes the problem that the strength of the locking mechanism in both connectors 3 and 4 is reduced, and in the embodiment shown in FIG. 4, the mold for molding the case 2 becomes complicated, making the product expensive. There was a problem with getting used to it.

[Purpose of invention]

The present invention was developed by focusing on these conventional problems, and the female connector of the case is provided with a plurality of narrow locking holes in parallel, and the male connector 4 is provided with a plurality of narrow locking holes.
An electrical connector that prevents parts from falling into the locking holes and further ensures sufficient strength of the lock arm by arranging multiple elastic levers that are engaged with the locking holes in parallel. The purpose is to provide the following.

[Example of idea]

The present invention will be explained in detail below based on the embodiment shown in FIG. Description of the same structural parts will be omitted.

That is, in this embodiment, a protrusion 18 extending in the mating direction of the male connector 4 is provided on the inner wall surface of the female connector 3 provided in the instrument housing case 2, and along both sides of the protrusion 18, respective thin strips are provided. Width locking hole 8,
8 will be provided. In addition, the above-mentioned protrusion 18 is provided at the center of the width direction of the elastic lever 9 provided on the above-mentioned male connector 4.
A slit 19 is provided into which the slit 19 is fitted, and narrow locking pawls 10, 10, which are engaged with the locking holes 8, 8, are protruded from both sides of the slit 19, respectively.

Therefore, according to this embodiment, since the locking hole 8 is formed with a narrow width, there is no problem that a falling part may pass through the locking hole 8 and fall into the housing case 2. is eliminated, and since the locking holes 8 are arranged in two rows, there is no lack of strength due to the plurality of locking claws 10, 10 that are engaged with these locking holes 8. , which can solve the conventional problems.

[Summary of the idea]

As described above, the present invention provides a male connector 4 in which a male connector 13 is accommodated, and a male connector 4 that fits together.
The male connector 4 has an elastic lever 9 extending in the fitting direction from the fitting end with the female connector 3. , when both the connectors 3 and 4 are fitted together, the locking claw 10 provided at the middle part of the elastic lever 9 engages the female connector 3.
In an electrical connector in which both the connectors 3 and 4 are connected by being locked in a locking hole 8 provided in the female connector 3, a projection 1 extending in the fitting direction in the female connector 3 is provided.
8 is located in the middle part of the locking hole 8, and when both the connectors 3 and 4 are fitted, the protrusion 1
This electrical connector is characterized in that the elastic lever 9 is provided with a slit 19 through which the numeral 8 penetrates.

[Effect of idea]

Therefore, according to this electrical connector, the protrusion 18 is provided in the middle part of the locking hole 8, in other words, the narrow locking hole 8 is formed on both sides of the protrusion 18. Inconveniences such as parts such as screws falling off and falling into the case through the locking hole 8 can be eliminated, and as a result, there is an effect that vibration noise of parts is no longer generated.
