Description

[Detailed Description of the Invention] Industrial Field of Use The present invention relates to a connector, and in particular, to ensure electrical conduction between a female contact and a male contact.

BACKGROUND OF THE INVENTION Connectors are used to enable wiring cords to be connected or disconnected. The connector is composed of a male connector and a female connector, and has a structure as shown in FIG.

As shown in the figure, a male connector 3 is constructed by making male contacts 1 protrude from a plurality of holes formed in a patch board 2 at approximately equal intervals. On the other hand, female contacts 5a are coupled to the cable 4a, and a plurality of female contacts 5a are connected to the holes 7a of the housing 6a.
A female connector 8a is configured by being fitted into the connector. In addition, the cable 4b has a female contact 5b.
are combined, and the female connector 8b is assembled by fitting the plurality of female contacts 5b into the holes 7b of the housing 6b.
is configured. Then, when the male contact 1 is inserted into the hole 7a or 7b, the male contact 1 comes into contact with a contact portion (described later) of the female contact 5a or 5b and becomes electrically conductive.

The male contact 1 is formed by pressing a flat plate 9 shown in FIG. 4a to form a part of a comb-shaped post 10 (see FIG. 4b), and then plated to prevent corrosion. The cross-sectional shape of the male contact 1 is rectangular, and one set of substantially parallel surfaces are smooth surfaces 11 and the other set of surfaces are sheared surfaces 12 formed by press working. The female contact 5a has a lance 14 formed on the same side as the opposing contact portion 13, as shown in FIG. 5a, and the lance 14 is attached to the housing 6a.
The female contact 5a is prevented from coming off from the housing 6a by inserting it into the lance receiver 15. The female contact 5b has a lance 1 at a position offset by 90 degrees from the opposing contact portion 13.
4 to prevent the female contact 5b from coming off from the housing 6b due to the lance 14 entering into a lance holder (not shown) of the housing 6b.

Problems to be Solved by the Invention However, the surface of the shearing surface 12 in FIG. When inserted into the shear plane 1
The plating on the protruding part of 2 may be scraped off, resulting in poor conductivity due to corrosion. Therefore, the third
When the mounting directions of the housings are different as shown in the figure as housings 6a and 6b, two types of female contacts 5a and 5b with different formation positions of the lances 14 are made as shown in FIGS. 5a and 5b, and the contact area is always Care had to be taken to ensure that 13 was in contact with the smooth surface 11.

Therefore, the purpose of the present invention is to solve such problems and provide a connector that does not cause the above-mentioned problems even when the male contacts are inserted into the holes in the housing regardless of the direction of the sheared surface of the male contacts. shall be.

Means for Solving the Problems The present invention provides that when a male contact is inserted into a hole in a housing into which a female contact is fitted,
The contact portions are formed at two locations substantially perpendicular to each other so that at least one contact portion contacts the smooth surface of the male contact regardless of the direction around the axis of the male contact.

Function The adjacent outer circumferential surfaces of the male contact are a smooth surface and a sheared surface, and the female contact fitted into the hole of the housing has two contact portions that are approximately perpendicular to each other.
Therefore, regardless of the direction around the axis of the male contact inserted into the hole of the housing, the smooth surface of the male contact always comes into contact with one of the contact portions. Therefore, only the sheared surface does not come into contact with the contact portion, and there is no risk that the plating on the sheared surface will be scraped off and the conductivity will deteriorate.

Embodiments Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. The present invention improves only the female contact, so parts that are the same as those of the conventional connector will be given the same reference numerals and explanations will be omitted, and only the different parts will be explained.

Embodiment 1 is shown in FIGS. 1a and 1b. A first crimped part 20a and a second crimped part 20b are formed at the base end of the female contact 20, and the first crimped part 20a
is wound around the wire 21a and crimped, and the second crimped part 2
The female contact 20 is coupled to the cable 21 by winding the cable 0b around the cable 21 and caulking it. In the center of the female contact 20, there is a first
A second support portion 20d is formed approximately at right angles to the support portion 20c, and a third support portion 20e is formed by bending the second support portion 20d by 180 degrees to the back side. The tip of the female contact 20 is configured as follows. A contact portion 20f is formed by bending the portion extending from the first support portion 20c at three places, a contact portion 20g is formed by bending the portion extending from the second support portion 20d at three places, and the contact portions 20f and 20g are mutually connected. It is almost a right angle. On the other hand, the third support part 20
By inserting a U-shaped cutting line in e and bending a part outward, a lance 20 is attached to the back side of the contact part 20g.
h is formed.

The female contact 20 is fitted into the hole 7a of the housing 6a or the hole 7b of the housing 6b, and the lance 20h is fitted into the lance receiver 15 or the like. When the male contact 1 is inserted into the hole 7a or 7b after the female contact 20 is attached to the housing 6a or 6b in this way, one of the contact portions 20f and 20g of the female contact 20 will necessarily touch the smooth surface 11. the other is necessarily in contact with the shear plane 12. In other words, since the smooth surface always comes into contact with one of the contact portions and there is sufficient conduction, one type of female contact is sufficient even if the mounting direction of the housing is different.

Next, Example 2 is shown in FIGS. 2a and 2b. The female contact 22 includes a support portion 22a, contact portions 22b and 22c that are integral with the support portion 22a and formed by bending and are perpendicular to each other, a first caulking portion 22d, and a second caulking portion 22e. A dimple 22f is formed instead of a lance. When using this female contact 22, a portion where the dimple 22f engages is formed in the housing into which the female contact 22 is fitted,
It is necessary to prevent the female contact 22 from coming off the housing.

Effects of the invention As explained above, according to the invention, since the female contact has two contact portions formed at substantially right angles to each other, one of the contact portions is always present regardless of the mounting direction of the housing. It will come into contact with the smooth surface of the male contact. Therefore, there is no need to be aware of the direction of the sheared surface of the male contact, and there is no need to create two types of female contacts with different lance formation positions as in the past.
