JPH10284148A - Fixing member for earth terminal - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a fixing member of an earth terminal by which the earth terminal can be fitted to a ground part easily, by equipping a hollow member of resin in which an engagement part to engage with a recessed and projecting part of a bolt is formed on an inside perimeter part, while being inserted by the bolt, and an energizing member which energizes the earth terminal toward the ground part when the hollow member is inserted through by the bolt. SOLUTION: After inserting a terminal (earth terminal) 11a through a bolt 13, a ring member (hollow member) 14 is inserted through the bolt 13, and is pushed in toward a ground part 12. While a recessed and projecting part 14a on an inside perimeter part of the ring member 14 engages with a recessed and projecting part 13a of the bolt 13, the terminal 11a is energized toward the ground part 12 by a protruding member (energizing member) 15 provided on the bottom of the ring member 14. As a result, an earth wire 11 can be grounded reliably by a simple work to insert the ring member 14 through the bolt 13 with one touch.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ground terminal fixing member, and more particularly, to a ground terminal provided on a wire harness or the like protruding from a ground portion provided on a predetermined portion of a panel of a vehicle body or an electric device. The present invention relates to a grounding terminal fixing member that can fix the grounding terminal to a grounding portion when the grounding terminal is inserted into a grounding bolt.

[0002]

2. Description of the Related Art Generally, in a vehicle body or an electric device,
The electrical components are connected by a wire harness, and a part of the wire harness is provided with a ground wire for grounding the electrical component, and the ground wire is attached to a ground portion provided at a predetermined position on the panel. Have been.

FIG. 4 shows a conventional structure for mounting a ground wire of this type, for example. In FIG.
Reference numeral 1 denotes a grounding ground wire branched from a wire harness, and a terminal 1a of the grounding wire 1 is inserted into a bolt 3 protruding from a grounding portion 2 provided at a predetermined portion of a vehicle body or a panel of an electric device. Later, the nut 4 is screwed into the bolt 3 to be in contact with the ground portion 2.

[0004] For this reason, the ground current of the wire harness flows from the terminal 1a of the ground wire 1 to the ground portion 2 side, and the wire harness is grounded.

[0005]

However, in such a conventional grounding structure of the ground wire 1, the terminal 1a
Is brought into contact with the grounding portion 2 by the nut 4 screwed to the bolt 3.
There is a problem that a nut tightening operation for fixing the terminal a with the nut 4 occurs, and the operation of mounting the terminal 1a is troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a ground terminal fixing member that can easily attach a ground terminal to a ground portion.

[0007]

According to the first aspect of the present invention,
To solve the above problem, when a ring-shaped ground terminal is inserted into a bolt protruding from the grounding portion, a fixing member that fixes this terminal to the grounding portion is inserted through the bolt, A resin hollow member formed with an engagement portion that engages with the concave and convex portion of the bolt on the inner peripheral portion,
And a biasing member formed at the bottom of the hollow member and biasing the ground terminal toward the ground portion when the hollow member is inserted into the bolt.

In this case, when the ground terminal is inserted into the bolt and then the hollow member made of resin is inserted into the bolt, the engaging portion formed on the inner peripheral portion of the hollow member is engaged with the concave and convex portion of the bolt. Since the grounding terminal is urged toward the grounding portion by the biasing member provided at the bottom of the hollow member, the grounding terminal can be easily brought into contact with the grounding portion. As a result, the earth terminal can be grounded by a simple operation of simply inserting the hollow member through the bolt with one touch.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are views showing one embodiment of a ground terminal fixing member according to the present invention. First, the configuration will be described. 1 and 2, reference numeral 11 denotes a grounding ground wire branched from a wire harness (not shown), and a terminal (grounding terminal) 11a of the grounding wire 11 is formed in a ring shape, and is provided on a panel of a vehicle body or an electric device. It is configured to be inserted into a bolt 13 protruding from a ground portion 12 provided at a location.

A resin ring member 14 constituting a hollow member is inserted through the bolt 13, and an inner peripheral surface of the ring member 14 is formed on an outer peripheral portion of the bolt 13. Uneven portion (engaging portion) 14a engaging with uneven portion 13a
The uneven portion 14a is formed over the inner peripheral surface of the ring member 14. A protruding member (urging member) 15 in the form of a disc spring is attached to the bottom of the ring member 14, and has a predetermined elastic force. In the present embodiment, the ring member 14 and the projection member 15 constitute a fixing member. Further, the projecting member 15 may be a spring provided at the bottom of the ring member 14 at a predetermined interval instead of the disc spring shape.

In order to ground the terminal 11a by the ring member 14 having such a configuration, as shown in FIG. 2A, after the terminal 11a is inserted into the bolt 13, the ring member 14 is inserted through the bolt 13. Then, as shown in FIG.
Push toward 12. At this time, the uneven portion 14a formed on the inner peripheral portion of the ring member 14 is engaged with the uneven portion 13a of the bolt 13, and the terminal 11a is connected to the ground portion 12 by the protrusion member 15 provided on the bottom of the ring member 14. Since the terminal 11a is urged toward the ground, the terminal 11a can be easily brought into contact with the grounding portion 12. As a result, the ring member 14 can be bolted with one touch.
The ground wire 11 can be grounded by a simple operation of inserting the wire harness into the wire 13, and the grounding of the wire harness can be reliably performed.

In this embodiment, the concave and convex portions of the bolt 13 are used.
An uneven portion 14a is formed over the inner peripheral portion of the ring member 14 as an engaging portion to be engaged with the ring 13a.
As shown in FIG. 3, a spring-like projection member 21 is projected from a predetermined portion of the inner peripheral portion of the ring member 14 and the projection member 21
An engagement piece 21a that engages with the concave and convex portion 13a may be provided at the tip end of the projection.

In this manner, the ring member 14 is bolted
13 when inserted and pushed in, the engagement member 21 bends and the engagement piece
21a allows the ring member 14 to move without engaging with the uneven portion 13a, and when the ring member 14 is pushed down to the ground portion 12, the engaging piece 21 is moved by the spring force of the engaging member 21 to the uneven portion 13a.
The ring member 14
The terminal 11a can be reliably brought into contact with the grounding portion 12 by preventing the terminal 11a from coming out of the terminal 13.

[0014]

According to the first aspect of the present invention, when the hollow terminal made of resin is inserted into the bolt after the ground terminal is inserted into the bolt, the engaging portion formed on the inner peripheral portion of the hollow member becomes a bolt. And the grounding terminal is urged toward the grounding portion by the biasing member provided at the bottom of the hollow member, so that the grounding terminal can be easily brought into contact with the grounding portion. As a result, the earth terminal can be grounded by a simple operation of simply inserting the hollow member through the bolt with one touch.
