Abstract

PURPOSE:To realize a small size and a high density mounting by forming a hole in the vertical direction to a rod-form contact maker to be inserted to a U-shape contact maker so as to bend from the force received from the U- shape contact maker. CONSTITUTION:A U-shape contact maker 1 consists of arms 2A and 2B of the length l, a projection 3 for contact arranged opposing to the arms, and a terminal 5 continued to the other side of the arms 2A and 2B. A rod-form contact maker 6 at the other side to which the contact maker 1 is geared consists of a contact surface to contact with the projection 3 for contact, and a hole 7 held by the contact surface. To realize a small size of the arms 2A and 2B, the l must be shortened, and the springing constant of the arms 2A and 2B is made very large. Consequently, a hole 7 is made to give some elasticity to the contact maker 6.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an electrical connection connector, and particularly to an electrical connection connector used for high-density packaging.

[Conventional technology]

Conventionally, in this type of electrical connector, when one contact has a U-shape, the other contact has a flat plate shape and is solid so that an appropriate contact force can be obtained.

[Problem to be solved by the invention]

When one of the contacts in the above-mentioned conventional electrical connector is U-shaped, the contact force needs to be set to an appropriate value in order to set the insertion force or removal force low.
The disadvantage is that the shape contactor requires a certain size or more, and cannot be adapted to miniaturization and high density.

An object of the present invention is to reduce the size of such a U-shaped contact and to provide an electrical connector that realizes high-density packaging.

[Means to solve the problem]

The electrical connection connector of the present invention includes a pair of parallel arm portions, and a contact protrusion that is disposed facing each other at a predetermined interval at the tip of each of the pair of arm portions, and a contact protrusion that is formed next to the other arm portion. a U-shaped contact having a terminal portion for external connection, and a hole portion in the longitudinal axis direction having a surface capable of contacting the contact protrusion and in a surface substantially perpendicular to the contact surface. and a rod-shaped contact, the rod-shaped contact being elastically engaged with the U-shaped contact.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of an electrical connection contactor showing an embodiment of the present invention.

As shown in FIG. 1, the U-shaped contact 1 in this embodiment
are arm parts 2A and 2B of length j, and these arm parts 2A
, 2B, and a contact protrusion 3 disposed facing each other at a predetermined distance from one end of each of the arms 2A, 2B, and a terminal portion 5 formed following the other of the arm portions 2A, 2B for connection to the outside, such as a printed board. It is composed of. The other rod-shaped contact 6 that engages with this U-shaped contact 1 has a contact protrusion 3.
The contact surface is made up of a contact surface for contacting the contact surface, and a hole 7 sandwiched between the contact surfaces. Here, in order to miniaturize the arm parts 2A and 2B of the U-shaped contact 1, it is necessary to make the notch part 4 very short.
The spring constants of A and 2B are very large. Therefore, it is impossible to insert the rod-shaped contact 6 into the hole so that the rod-shaped contact 6 has some elasticity against the force received from the contact protrusion 3 of the U-shaped contact 1 unless it is made of an elastic material. Section 7 is open.

FIGS. 2(a) and 2(b) are front views showing the U-shaped contact and the rod-shaped contact shown in FIG. 1 before and after insertion, respectively.

As shown in FIGS. 2(a) and 2(b), the distance a between the contact projections 3A and 3B of the U-shaped contact 1 is smaller than the thickness b of the rod-shaped contact 6. Therefore, when the rod-shaped contact 6 is inserted into the U-shaped contact 1 consisting of the arm parts 2A, 2B, etc., the hole 7 of the contact 6 is deformed, and both the upper and lower contact surfaces of the contact protrusions 3A, 3B and the contact 6 are deformed. are connected. That is, it means that the rod-shaped contactor 6 is an elastic body.

FIG. 3 is a sectional view of an electrical connector in which the contacts shown in FIG. 1 described above are mounted in a housing.

As shown in FIG. 3, the U-shaped contact 1 is mounted on the housing 8, and the terminal portion 5 is attached to the printed board 11. Further, the rod-shaped contact 6 is fixed inside the guide housing 9. In this way, by improving contact position accuracy,
Contact stability can be maintained. Note that here, the terminal portion 5 of the U-shaped contact 1 is soldered to the printed board 11,
A part of the contactor 6 is connected to a backboard 12 by a fixing part 10 without soldering.

In manufacturing the electrical connection connector of this embodiment, in the stamping process for manufacturing the rod-shaped contact 6 which is the counterpart of the U-shaped contact 1, there is a step of drilling a hole, and a rod-shaped Position of contact 6 at 90°
It includes a step of bending it vertically and a step of collapsing it in the vertical direction to widen the contact area.

〔Effect of the invention〕

As explained above, the electrical connection connector of the present invention is
By drilling a vertical hole in the rod-shaped contact inserted into the U-shaped contact so as to bend in response to the force received from the U-shaped contact, elastic engagement can be realized.
This has the effect that the shape contactor can be made smaller and high-density packaging is possible.
