BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a connector on which a manufacturing date, a manufacturing time and the like are marked.

[0002]

2. Description of the Related Art Manufacturers, product names, model numbers, etc. are conventionally displayed on connectors used for electrical wiring, but connectors used for electrical wiring of automobiles will be recalled in the future. As a measure against this, the date of manufacture of the connector is also displayed.

Conventionally, when the manufacturing date is displayed on the connector, the manufacturing date is stamped after the connector is manufactured, or the manufacturing date is printed in advance by attaching a label to the connector. Is generally adopted.

[0004]

[Problems to be Solved by the Invention] However, in the conventional method of displaying the manufacturing date after manufacturing the connector, the number of steps is increased, so that the productivity is poor and the manufacturing date different from the manufacturing date is displayed. There was a problem such as lack of reliability.

The present invention has been made for the purpose of improving the above problems, and an object thereof is to provide a connector capable of engraving the manufacturing date and time at the time of manufacturing the connector.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention uses a date mark pin for engraving at least one of the manufacturing date and time, product name, model number and the like to simultaneously form a connector body. At least one such as a manufacturing date and time, a product name and a model number is stamped on the side surface of the connector body.

[0007]

With the above construction, since the manufacturing date and the like can be stamped at the same time as the connector is manufactured, it is not necessary to stamp in a separate process, and a marking error does not occur.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail with reference to the drawings shown in FIGS. 1 shows a connector in which a manufacturing month and a manufacturing date are stamped on the side surface of a connector body, FIG. 3 shows a mold for manufacturing the connector, and FIG. 4 shows a date mark pin stamped on a connector incorporated in the mold.

The mold comprises a fixed mold 1, a movable mold 2 provided above the fixed mold 1 and a slide core 3 provided in the fixed mold 1, and a parting line of the slide core 3 is provided. A date mark pin 4 is detachably fitted on the surface.

A cavity 1a for molding the connector 5 is formed in the fixed mold 1, and the slide core 3 is provided on the side of the cavity 1a so as to be movable back and forth. A plurality of recessed holes 3a are formed on the end surface of the cavity 1a on the side of the cavity 1a at intervals in the longitudinal direction of the cavity 1a. It is fitted.

The date mark pin 4 is shown in FIG.
As shown in (d) to (4), those representing the year of manufacture, month of manufacture, date of manufacture, and time of manufacture are prepared in advance, and can be selected according to the purpose of use. When displaying the time, the date mark pin 4 shown in (a) to (d) of FIG. 4 is used by being attached to the concave hole 3 a of the slide core 3.

On the other hand, a pin hole 3b is formed in the slide core 3 obliquely in the vertical direction, and a guide pin 6 provided on the movable mold 2 side is fitted into the pin hole 3b from obliquely above. It is like this.

A backup member 7 is provided behind the slide core 3, and between the taper surface 7a formed on the backup member 7 and the taper surface 3c formed at the rear end of the slide core 3. When the wedge member 8 provided on the movable mold 2 side enters, the slide core 3 can be moved back and forth.

Next, a method of manufacturing the connector 5 will be described. In molding the connector 5, first, the fixed mold 1 is formed.
A plurality of pins 5b to be embedded in the connector body 5a are set in a predetermined arrangement in the cavity 1a of the above, and the recess mark 3a of the slide core 3 is provided with a date mark pin for marking the manufacturing date and time. 4 is set in a predetermined arrangement.

Then, when the movable mold 2 is lowered in this state, the slide core 3 is advanced to the cavity 1a side by the wedge member 8 provided on the movable mold 2 side, and at the same time, the slide core 3 is moved by the guide pin 6. Positioning 3 is performed.

Next, in this state, resin is injected into the cavity 1a of the fixed mold 1 to mold the main body 5a of the connector 5. At this time, the pin 5b set in the fixed mold 1 in advance is the main body 5a. The date and time of manufacture are stamped on the side surface of the main body 5a by the date mark pin 4 while being embedded therein.

After that, when the movable mold 2 starts rising,
At the same time when the pressing of the slide core 3 by the wedge member 7 is released, the slide core 3 is retracted by the guide pin 6, so that the fixed mold 1 is divided in the vertical direction to complete the molding from inside the cavity 1a. The connector 5 can be taken out.

The connector 5 can be continuously manufactured by repeating the above operation.

In the above embodiment, the case where the manufacturing date and time are put on the side surface of the connector body 5a has been described, but the product name, model number and the like can be stamped by the same method.

[0020]

As described above in detail, the present invention is capable of engraving the manufacturing date, time, product name, model number, etc. on the side surface of the connector body at the same time when molding the connector. In addition, the number of manufacturing steps is reduced as compared with the one engraved after the connector is manufactured, so that the productivity can be significantly improved. In addition, the manufacturing date, time, model number, etc. are not imprinted by mistake, which improves the reliability of the product and when used for electric wiring of automobiles,
Even if a recall occurs, the accurate manufacturing date can be grasped, so there is an effect that appropriate measures can be taken.
