Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to an improvement of a female type electrical connector having a receptacle portion for receiving a mating tab-shaped male terminal.

[Conventional technology]

The fifth as a female type electrical connector used for electrical connectors,
6 There are some as shown in Fig.

That is, the female type electrical connector A includes a receptacle portion A _{1 on} the front side of the substrate 1, a conductor crimping piece 2 and an insulator crimping piece 3 on the rear side.
It has a wire connection part A ₂ consisting of and.

The receptacle portion A ₁ includes the substrate 1 and the standing side walls 4, 4 on both sides.
And the free edges 5,5 'of the side walls 4,4 are folded over the substrate and overlapped to receive a mating tab between the folded overlap and the substrate.

In addition, the elastic tongue 6 extends from the tip of the substrate 1 to the receptacle portion.
A contact plate portion 7 that is folded back toward the inside of A ₁ and faces the elastic tongue piece 6 is formed by stamping on the inner free edge portion 5 ′ inside the receptacle portion A ₁ .

As shown in FIG. 6, this electrical connector A is inserted into the terminal accommodating chamber 11 of the connector housing 10 and the projection 13 of the flexible locking arm 12 engages with the locking hole 8 provided in the substrate 1. The stabilizers 9 that are locked together and hang vertically on both lower surfaces of the substrate 1 are
The groove (not shown) is engaged to prevent rattling to the left and right.

[Problems to be solved by the device]

In the above prior art, when the male and female terminals are fitted together, in order to prevent the male terminal 14 and the female terminal, that is, the tip portions 5a, 5a 'of the receptacle portion A _{1 from} hitting each other, the contact plate portion by punching is used. 7 is provided so that a space X is provided between the inner end portion 5a 'and the inner tip portion 5a' at the time of proper insertion.

However, also in this case, assuming that the male terminal 14 is obliquely inserted with respect to the receptacle portion A ₁ , the clearance X should be set as large as possible.
The tip 14a of the above may abut against the above-mentioned tip 5a 'to cause the terminal to be dented or settled, and further, the terminal may be pulled out.

However, if the clearance X is increased, the height Y of the receptacle portion A ₁ is increased correspondingly, and the terminal is increased in size.

The present invention has been made by paying attention to the above-mentioned points, and has a large clearance X without increasing the size of the terminal.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, in the present invention, firstly, an inner and outer top plate portion, which is formed by folding free edges of both side walls of the substrate above the substrate and superposing the substrate, is provided. In a female-type electrical connector having a receptacle part adapted to receive a mating male terminal between parts, a contact plate part is provided on the inner top plate part, and a front end part is provided with a bulge located in a notched space at the front end part of the outer top plate part. Adopting a configuration in which a projecting plate portion is provided and a tapered guide plate portion is formed from the bulging plate portion to the contact plate portion, and secondly, the contact plate by punching inward at the intermediate portion of the inner top plate portion. In addition, a notch space is provided at the front end and a tapered guide plate portion located in the notched space is cut and raised in the outer top plate portion so as to be continuous with the tapered guide plate portion of the inner top plate portion.

〔Example〕

Female electrical connector A 'is the receptacle portion A ₁ in front of the substrate 1' shown in the first and second figures, the wire connecting portion A ₂ backward '
have.

In the receptacle portion A ₁ ′, side walls 4 and 4 are provided upright on both sides of the substrate 1 as in the conventional example (only one side wall is shown), and the free edge portions of the side walls 4 and 4 are bent and overlapped above the substrate. The inner top plate portion 5'and the outer top plate portion 5
The mating tab-shaped male terminals are received between the inner and outer top plate portions 5 and 5'and the substrate 1.

In addition, the elastic tongue 6 extends from the tip of the substrate 1 to the receptacle portion.
A contact plate portion 7 which is formed by folding back toward the inside of A ₁ and which faces the elastic tongue piece 6 is formed by punching inward from the inner top plate portion 5 ′. The outer top plate 5 has a notch space at the front end.
The inner top plate 5'is formed in a short length so as to have 15
A bulged plate portion 16 is formed at the front end portion of the bulge plate 16 and is located in the cutout space 15. The bulged plate portion 16 pierced to the outside extends from the bulge plate portion 16 pierced to the inside. The tapered guide plate portion 17 is formed.

Therefore, between the contact plate portion 7 and the tip end portion 16a of the bulging plate portion 16 with which the mating tab-shaped male terminal collides, a gap of X + α obtained by adding the plate thickness α to the gap X described in the conventional example. Is formed.

In the embodiment shown in FIGS. 3 and 4, the front end portion of the inner top plate portion 5'in which the contact plate portion 7 is punched out is notched so that the notched space 1 is formed forward.
5 ′ is formed, and a tapered guide plate portion 17 ′ located in the cutout space 15 ′ is cut and raised in the outer top plate portion 5 to cover the tip portion 5 a ′ of the inner top plate portion 5 and the tapered guide plate portion 17 ′. Is connected to the tapered guide portion 17 ″ of the inner top plate portion 5 ′ through the cutting portion. Therefore, in this case as well, a gap X + α is formed by adding the plate thickness α to the gap X. To be done.

[Effect of device]

As described above, the present invention provides the board with the inner and outer top plates formed by folding the free edges of both side walls above the board and receiving the mating male terminals between the board and the top plate. In the female type electrical connector having the receptacle part, the contact plate part is provided on the inner top plate part and the bulging plate part located in the notch space at the front end of the outer top plate part is provided at the front end part. Portion to the contact plate portion, a tapered guide plate portion is formed, or a contact plate portion by punching inward is provided in the middle portion of the inner top plate portion and a notch space at the front end is provided, and the outer top plate portion is provided with Since the tapered guide plate portion located in the cutout space is cut and raised to be continuous with the tapered guide plate portion of the inner top plate portion,
The insertion gap of the mating male terminal in the receptacle portion of the female type electrical connector can be increased without increasing the height of the receptacle portion, which is effective in preventing the mating male terminal from abutting.
