Description

[Detailed description of the invention] [Industrial application field] The present invention is a lead wire fixing insulator that insulates and fixes the connection between an electrode and a lead wire terminal, and particularly a fuel sender flange in a fuel sender gauge for a vehicle. This invention relates to a lead wire fixing insulator used for fixing lead wires.

[Conventional technology]

In the fuel sender gauge for vehicles,
An electrode is installed on the flange of the fuel tank in order to detect changes in the liquid level in the fuel tank and output it as an electrical signal.A lead wire is connected to the electrode on this flange to generate an alarm device. signals are now being supplied to

Figure 2 is a diagram explaining a conventional insulating seat used to insulate and reinforce the connection part when connecting the electrode and lead wire as described above, and Figure B is similar to Figure A. It is a figure which shows the state seen from the arrow side shown.

1 is a lead wire connected to an alarm device, etc., 20 is a resin insulating seat for fixing the connection part as will be explained later, and 3 is a terminal 5 provided at the end of the lead wire to the flange 4. A rivet 6, which is crimped and fixed in order to connect to the formed electrode (not shown), is a filler filled inside the insulating seat 20 to insulate the connection portion from the outside.

A reinforcing portion 21 is formed on the edge of the insulating seat 20, and the reinforcing portion 21 pushes the lead wires 1 in a bundled state toward the flange 4, and the filler 6 inside the insulating seat 20 is It is designed so that it will not be destroyed by levitation of the lead wire 1 or the like.

[Problem that the invention attempts to solve]

In the conventional insulating seat as described above, since the reinforcing part 21 forms a ring-shaped body together with the main body of the insulating seat, the lead wire 1 is connected to the reinforcing part 2 when making wiring connections.
1 and place the insulating seat 20 on the flange 4, and in this state, it is necessary to insert the rivet 3 into the terminal 5 of the lead wire 1 and tighten it.

Therefore, not only is the work complicated, such as having to pass through the reinforcing part 21, but also the lead wire 1 has to pass through the reinforcing part 21.
When the insulator 20 is installed on the flange 4 by passing through the terminal 5, the elasticity of the lead wire 1
There was a problem in that the workability when tightening the rivet 3 was poor because the rivet 3 was lifted up.

[Means and actions for solving problems]

The lead wire fixing insulating seat of the present invention, which was created to solve the above problems, is attached to a fixed substrate on which an electrode is arranged, and has a recess for accommodating the terminal of the lead wire connected to the electrode, and The lead wire connected to the electrode is inserted through the recess, and the recess has an annular reinforcing portion formed from the edge of the recess in a plane substantially including the edge. In the lead wire fixing insulator for insulating and fixing a terminal, the annular reinforcing part is provided with first and second parts that protrude from the edge of the recess and whose tip ends overlap with each other in a direction facing the fixing substrate. The terminal of the lead wire is formed with a claw, and a passage for fitting the lead wire connected to the electrode into the reinforcing part is formed at the overlapping part of the first and second claws. After the lead wires are connected to the electrodes of the fixed substrate, the lead wires can be disposed between the reinforcing portion and the fixed substrate through the passages of the reinforcing portion.

〔Example〕

Fig. 1 is a diagram showing the usage state of the lead wire fixing insulator of the embodiment of the present invention, Fig. 1B is a diagram showing the state seen from the direction of the arrow in Fig. This is a lead wire fixing insulating seat, and the other members are the same as those of the conventional one explained with reference to FIG. 2, so they are shown with the same symbols as in FIG. 2.

The lead wire fixing insulating seat (hereinafter simply referred to as the insulating seat) 2 is formed in the shape of a flat box having a recess 2d for accommodating the terminal 5 of the lead wire 1, and a claw 2a is provided at the edge as a reinforcing part. and claws 2b are formed.

To make a wiring connection using this insulator 2, first place the insulator 2 between the terminal 5 of the lead wire 1 and the flange 4, tighten the rivet 3, and attach the terminal 5 to the flange 4 (not shown). Connect to the electrode. Next, the lead wire 1 is arranged between the claw 2a and the flange 4 via the notch 2c formed in the overlapping part of the claw 2a and the claw 2b, and the recess 2d of the insulating seat 2 is inserted.
The work is completed by filling the filler 6 and sealing the connection.

In this way, since the lead wire 1 can be connected first, the terminal 5 will not be lifted up due to the elasticity of the lead wire 1 when tightening the rivet as in the conventional case. The crimping work of the rivet 3 can be easily performed.

As can be seen from FIG. 1B, in this embodiment, a passage is formed between the pawls 2a and 2b by the notch 2c, but the gap between the notch 2c is eliminated. When installing the lead wires, the elasticity of the claws 2a may be used to create gaps in the notches 2c so that wiring can be performed.

[Effect of idea]

As explained above, according to the lead wire fixing insulator of the present invention, the terminal of the lead wire connected to the electrode of the fixed board is accommodated in the recess, and the recess is filled with a filler material to insulate the terminal of the lead wire. In addition to fixing the
In a lead wire fixing insulator in which a lead wire is inserted through an annular reinforcing part formed at the edge of the recess to reinforce the connection part, the annular reinforcing part is provided protruding from the edge of the recess and the tip is inserted. The reinforcing portion is formed by first and second claws that overlap each other in a direction facing the fixed substrate, and a passage is formed in the reinforcing portion at the overlapping portion of the first and second claws. The lead wire can be easily disposed between the lead wire and the fixed substrate, and work efficiency such as rivet tightening work when connecting the lead wire can be improved.
