Abstract

PURPOSE:To improve the reliability of wire holding of a pressure-contact connector, in which falling-out of a cover from a housing is prevented even in the case where the tensile force is applied to the wire. CONSTITUTION:A wire 31 to be connected is stretched over a slot 11 of a pressure-contact terminal 2 and wire pinching grooves 2 provided in both side surfaces of a housing 3, and the wire 31 is made cross each other under the housing 3, and a cover 4 is fitted out of the housing 3. Then, the wire 31 is pressed into the pressure-contact terminal 2, and arranged from the top surface 3a to both side surfaces 3b of the housing 3, and the wire 31 cross each other in the lower surface 3c of the housing 3. Consequently, at the time of wiring or incorporating, even in the case where the tensile force is applied to the wire 31, since the wire 31 receives the force in the direction for winding around of the housing 3, falling-out of the cover 4 from the housing 3 can be prevented.

The electric wire 31 to be connected is passed through the lower surface of the housing 3 once, and the electric wire 31 is passed over the slot 11 of the pressure contact terminal 2 on the upper surface of the housing 3 and the electric wire holding groove 12 on both side surfaces of the housing 3 with both hands to be temporarily locked, Furthermore, the housing 3
The electric wires 31 are crossed on the lower surface of the. Then, the insulating coating of the electric wire 31 lightly bites into the slot 11, and at the same time, the electric wire 31
Is drawn into the wire holding groove 12 and locked. In this way, after all the electric wires 31 to be connected are primarily locked to the press-connecting connector 1, the cover 4 is fitted into the housing 3, and the long groove 22, the engaging piece 13, the engaging hole 23, and the lock claw 1 are fitted.
4 and 4 are engaged with each other. Then, the electric wire 31 is press-fitted into the slot 11 by the projection 21 provided on the upper portion of the inner surface of the cover 4, the insulating coating is broken, and the core wire contacts the press-connecting terminal 2. Then, the housing 3 is pulled out from the supporting jig 5 in the direction of arrow A. In this state, as shown in FIG. 2, the electric wire 31 is press-fitted into the press-contact terminal 2, is arranged along the side surfaces 3b from the upper surface 3a of the housing 3, and intersects with the lower surface 3c of the housing 3.

Receives only the force in the direction of winding around the housing 3, and does not exert the force in the direction of pushing up on the cover 4. Therefore, the cover 4 does not come off from the housing 3, and the reliability of holding the electric wire 31 by the press contact connector 1 is improved. Further, when a tensile force in the direction of the arrow R acts on the electric wire 31,
The electric wire 31 is wound around the housing 3 so that the pressure contact terminal 2
As a result, the wire tends to be displaced in the direction in which the pressure contact pressure increases, so that the electric wire 31 can be prevented from rising from the pressure contact terminal 2 and the contact resistance value can be stabilized. Further, the cover 4 can be prevented from coming off with a simple structure without increasing the size and weight of the press-connecting connector 1.

In addition to the configuration of the embodiment, a pair of buffer portions 41 projecting downward are provided on both sides of the lower surface 40c of the housing 40. That is, the cushioning portion 41 is provided along both sides of the lower surface 40 c of the housing 40 and extends downward along the longitudinal direction of the housing 40. The cushioning portion 41 elastically contacts the electric wire 31 inside the electric wire 31 and winds the electric wire 31 in the winding direction. It is flexibly deformable.

Since the wire 1 bends in the pulling direction of the electric wire 31 and absorbs the pulling force, the electric wire 31 is not damaged at the corner edge of the housing 40, and the electric wire 31 can be protected from the pulling force. This is particularly effective when a pulling force is suddenly applied to the electric wire 31. In this example, a pair of cushioning portions 41 are provided on both sides of the lower surface 40c of the housing 40. For example, the lower surface 40c of the housing 40 may be provided at another position.
