Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to the structure of a connector used for connection with a printed board or the like provided in various meters for vehicles.

[Conventional technology]

Conventionally, a connector structure has been proposed in which a connector for connection with another printed board is fixed on a printed board (see Japanese Utility Model Application No. 62-5486).

In addition, as a connector for connection with a printed board provided on a vehicle meter, as shown in FIG. 3, a plurality of terminals 1 that can contact a printed board (not shown)...
In order to prevent damage to the terminals 1...1 before connecting the connectors, the connector body 2 accommodates the terminals 1 and has almost the front half of the upper wall open.
Insert the terminal protection cover 3 in advance and connect the terminals 1...1
When the printed board is inserted into the connector body 2 from the front of the connector body 2 and connected to the connector, the terminal protection cover 3 slides backward and comes off from the connector body 2, and the terminals 1... ...A device in which 1 is in contact with a printed board is known.

However, in this connector structure, the positioning of the terminals 1...1 with respect to the connector body 2 is uncertain, so the terminals 1...1 may come off from the connector body 2, or if a printed board is inserted into the connector body 2. There was a problem in that the position of the terminals 1...1 could be shifted when the terminals were in the same state.

Therefore, conventional connectors have been provided with a terminal protection cover that is attached to the connector body from the front and covers the open area on the top wall of the connector body, and a locking piece that is inserted into the connector body from the rear to position the terminals. structure is considered.

[Problem that the invention attempts to solve]

However, the above-described connector structure requires a locking piece in addition to the terminal protection cover, resulting in an increase in the number of parts and an increase in cost.

[Means for solving problems]

In order to solve the above problems, the connector structure according to the present invention includes a connector body that accommodates a terminal, and a terminal protection cover that is slidably inserted into the connector body and covers the terminal before the connector is connected. In the connector structure, the terminal protection cover is provided with a rib that abuts the terminal at a terminal covering position before the connector is coupled to position the terminal.

[Effect]

According to the above configuration, the terminals are reliably positioned at the predetermined positions by the ribs provided on the terminal protection cover before the connectors are connected, so that the terminals cannot be removed from the connector body or the terminals can be removed while the connectors are connected. The positional shift will no longer occur.

Further, since the positioning rib is integrally formed with the terminal protection cover, there is no need to provide a locking piece separately from the terminal protection cover.

〔Example〕

An embodiment of the present invention will be described below with reference to FIGS. 1a and 2b and FIG.

As shown in FIG. 1B, a recess 6 is formed at the rear of the vehicle meter 5, and a flexible printed board 7 projects approximately horizontally into the recess 6 from within the vehicle meter 5. An engaging protrusion 8 is provided at the rear end of the lower surface of the recess 6 .

As shown in FIGS. 1a and 2, the connector 9 for coupling with the flexible printed board 7 includes a connector body 10. As shown in FIGS. Almost the front half of the upper wall of the connector body 10 is open.
An engaging claw 1 is provided on the lower surface side of the bottom wall portion of the connector body 10.
1 is formed, and this engaging claw 11 is adapted to engage with the engaging protrusion 8 when the connector 9 is connected to the flexible printed board 7.

Three partition walls 12...12 extending in the longitudinal direction of the connector main body 10 are provided within the connector main body 10 with a predetermined interval between them and the upper wall. divided into two spaces. In each space, a flexible holding claw 13 is provided for the connector body 1.
It protrudes from the bottom wall of 0.

A terminal 14 is housed in each space of the connector body 10, and one end of an electric wire 15 is connected to each terminal 14. Each terminal 14 has an engagement hole 16
are provided, and each terminal 14 is held in the connector body 10 by engaging each holding claw 13 with an engagement hole 16 of each terminal 14.

A terminal protection cover 17, which is shorter in length than the connector main body 10, is inserted into the upper part of the partition walls 12...12 in the connector main body 10 so as to be slidable in the front and back direction, and the terminal protection cover 17 has a front end as shown in FIG. 1a. It is adapted to cover the upper part of each terminal 14 when slid to the position. Both ends of the terminal protection cover 17 in the width direction are
The terminal protection cover 1 is slidably fitted into a pair of guide grooves 18 formed at opposing positions on the inner surface of each side wall of the connector main body 10.
7 height position is regulated. Further, a bent portion 20 that is bent upward is formed at the front end portion of the terminal protection cover position 7. Furthermore, four ribs 21 . It can be touched from the rear. The contact portion 22 is formed integrally with the terminal 14 by caulking a rising portion from the side of the terminal 14.

In the above configuration, when assembling the connector 9, the four terminals 14 respectively connected to the electric wires 15 are inserted into each space of the connector body 10 divided by the partition walls 12...12, and then, as shown in FIG.
As shown in FIG. 2, the terminal protection cover 17 is inserted into the connector body 10 from the rear and slid to the front end inside the connector body 10 to cover the upper part of each terminal 14. When this terminal protection cover 17 is inserted, the abutment portion 22 of each terminal 14 is pressed forward by the rib 21, and each terminal 14 moves forward within the connector body 10 to a predetermined position, that is, each engagement hole 16. is positioned at a position where each holding claw 13 engages, and thereby each terminal 14 is held by the holding claw 13.
In this way, each holding claw 13 and each engagement hole 16 are reliably engaged when the terminal protection cover 17 is inserted, so that the problem of the terminal coming off is reliably prevented.

Next, the four terminals 14 and the terminal protection cover 1
When the connector 9 containing the terminals 7 is inserted into the recess 6 of the vehicle meter 5, each terminal 1 is inserted as shown in FIG. 1b.

1 is engaged with the engagement protrusion 8, and the connector 9 is prevented from coming off from the recess 6. Note that when the connector 9 is inserted into the recess 6 , the bent portion 20 at the front end of the terminal protection cover 17 abuts against the rear wall of the vehicle meter 5 , so the terminal protection cover 17 cannot be inserted into the recess 6 . Instead, it slides rearward relative to the connector body 10.

In the above embodiment, a connector for connecting to a flexible printed board was described, but the connector of the present invention can also be used for connecting to a normal printed board, etc., and the number of terminals accommodated in the connector body can also be changed arbitrarily.
