BACKGROUND OF THE INVENTION
The present invention relates to a connector molding die capable of molding a plurality of types of connectors by rearranging inserts and the connector.
[0002]
[Prior art]
The conventional connector molding die 1 shown in FIG. 10 includes a mold body 1A including a fixed mold 2 and a movable mold 3 that can be opened and a slide pin 4 that slides in a direction perpendicular to the mold opening direction. By changing the combination of the inserts 3A and 4A assembled to the movable mold 3 and the slide pin 4, two types of female connectors 5 and 6 that are conventionally known can be molded. The female connectors 5 and 6 are shown in comparison with FIG. 11 and FIG. 12, and the basic structure is common to each other, the display contents of the part number display portion 7 stamped on the outer surface, and for preventing erroneous assembly. Only the arrangement of the ribs 8 is different from each other. The mating connectors 5A and 6A of both connectors 5 and 6 are formed with rib receiving grooves 9 corresponding to the ribs 8, so that the connectors cannot be engaged with each other except in a regular combination.
[0003]
[Problems to be solved by the invention]
By the way, in above-mentioned metal mold | die 1, the combination of both nesting 3A and 4A may be mistaken, and an irregular connector may be shape | molded. As a specific example thereof, as shown in FIG. 11, in a connector in which a product number “C-0001” is engraved on the product number display portion 7, the rib 8 is on the head side of the product number (the letter “C” side) ) May be molded in an irregular connector in which the rib 8 is disposed on the end side of the product number. In such a case, in the conventional connector, the product number display section 7 is only changed in number, and the display is often small, so it is difficult to check the product number, and it is an irregular product. It was hard to notice. In addition, even if it is an irregular product, it will be connected to the connector as long as the rib arrangement corresponds to the rib receiving groove 9 of the mating connector. There was a risk that an unauthorized product would be washed away in the subsequent process.

(See FIGS. 4 and 5). Here, when the first nesting 26 is described by type, “V” or “W” is added to the end of the reference numeral “26” to distinguish them, and the same applies to the second nesting 27. The following description will be continued assuming that the product number of one connector 40V shown in FIG. 4 is “C-100” and the product number of the other connector 40W shown in FIG. 5 is “C-200”.
[0013]
The molding surface 27A of the second insert 27 attached to the movable mold 23 is flush with the molding surface 24A at the tip of the slide pin 24 in the mold closed state of the mold body 21 (see FIG. 1). In 27A, as shown in FIG. 2, a rib-shaped groove 28 is recessed along the mold opening direction. One end of the rib molding groove 28 is open to the side surface of the second insert 27 and is closed by the tip side surface 24C (see FIG. 2) of the slide pin 24 in a mold-closed state.
[0014]
In the second insert 27V for the product number “C-100” shown in FIG. 2 among the second inserts 27, the rib molding groove 28 is arranged on the right side when viewed from the slide pin 24 side. On the other hand, in the second insert 27W for the product number “C-200” shown in FIG. 3, the rib molding groove 28 is arranged on the left side when viewed from the slide pin 24 side. As a result, a misassembly prevention rib 43 (hereinafter referred to as “extension prevention rib 43”) extending in the fitting direction with the mating connector at a position on either side of the one side surface 42A of the connector housing 42 provided in each connector 40V, 40W. , Referred to as “rib 43”) (see FIG. 4 or FIG. 5).
[0015]
On the other hand, the first nest 26 is fitted into a depressed portion 24 </ b> B formed at an intermediate portion in the mold opening direction of the tip of the slide pin 24. Molded surfaces 24A and 24A of the slide pin 24 are arranged on both sides of the depressed portion 24B, and these and the molded surface 26A of the first insert 26 are flush with each other.
[0016]
On the molding surface 26 </ b> A of the first insert 26, a product number engraving portion 29 is provided along the edge portion on the side away from the second insert 27. Then, in the first insert 26V for the product number “C-100” shown in FIG. 2, a shallow groove shaped as “C-100” is formed in the product number engraving portion 29, and the product number “C-100” shown in FIG. In the first insert 26W for "C-200", a shallow groove shaped as "C-200" is formed in the product number engraving portion 29. As a result, as shown in FIG. 4 or FIG. 5, the product number display portion consisting of the characters “C-100” or “C-200” slightly protruding from the rear end side of one side surface 42 </ b> A of the connector housing 42. 44 is engraved.
[0017]
Now, the molding surface 26A of the first insert 26 is provided with a molding recess 30 according to the present invention on the side close to the second insert 27. The molding recess 30 has the same cross-sectional shape as the rib molding groove 28 of the second insert 27. In the first insert 26V for the product number “C-100”, the rib of the second insert 27V for the product number “C-100” is used. The first nest 26W for the product number “C-200” is arranged on the coaxial line of the molding groove 28 (see FIG. 2). Is arranged (see FIG. 3). Accordingly, as shown in FIG. 4 or FIG. 5, the space between the rib 43 and the product number display portion 44 in one side surface 42A of the connector housing 42 is shifted to either the left or right depending on the product number. An identification protrusion 45 is provided at the position.
[0018]
The mating connector (see FIG. 7) of the connector 40V of the product number “C-100” includes a rib housing groove 52 in the hood portion 51 by expanding a part of the rectangular hood portion 51 outward. When the connector 40V is inserted into the hood portion 51, the ribs 43 and the identifying protrusions 45 aligned in the connector 40V move along the rib receiving grooves 52 of the hood portion 51, and are fitted together. In the completed state, the flange 46 provided at the rear end of the connector 40 </ b> V comes into contact with the front end surface of the hood portion 51. Further, the mating connector for the connector 40W of the product number “C-200” has a structure that differs only in the arrangement of the rib receiving grooves 52.
[0019]
Next, the effect of this embodiment having the above-described configuration will be described.
In order to mold the connector 40V of the product number “C-100” with the mold 20 of this embodiment, as shown in FIG. 2, the first insert 26V and the second insert 27V for the product number “C-100” are formed. The synthetic resin is poured into the mold 20 by assembling the mold body 21. Then, as shown in FIG. 4, the rib 43 and the identification protrusion 45 are aligned along the mating direction with the mating connector at a position closer to the left side as viewed from the rear surface of one side surface 42 </ b> A of the connector housing 42. The connector 40V is molded, in which a product number display portion 44 made of characters "C-100" slightly protruding from the rear end side of the one side surface 42A is engraved.
[0020]
Next, in order to mold the connector 40W of the product number “C-200”, the first insert 26V and the second insert 27V for the product number “C-100” are removed from the mold body 21, and the product number “C-200” is replaced with the product number “C-100”. The first insert 26W and the second insert 27W for “C-200” are assembled to the mold body 21 (see FIG. 3). When the synthetic resin is poured into the mold 20, as shown in FIG. 5, the rib 43 and the identification protrusion 45 are located at a position on the right side of the side surface 42A of the connector housing 42 as viewed from the rear surface. Are arranged in a straight line along the mating direction with the mating connector, and a connector 40W is molded in which a product number display portion 44 made of characters "C-200" is engraved.
[0021]
For example, as shown in FIG. 6, in a state where the first insert 26W for the product number “C-200” and the second insert 27V for the product number “C-100” are inadvertently attached to the mold body 21. When the connector is molded, it is as follows. That is, as shown in FIG. 7A, the molded product has a form in which the rib 43 and the identification protrusion 45 are arranged separately on the left and right sides on one side 42A of the connector housing 42. Since the rib 43 and the identification protrusion 45 in FIG. 4 and FIG. 5 are clearly different from the form arranged in a straight line, when the connector is discharged from the mold 20, it is easily irregular by visual inspection. You can notice that it is a simple connector. Then, the insert can be reassembled into the correct one before molding a large number of irregular connectors.
[0022]
Further, when the connector is discharged from the mold 20 and sent to the connector assembly process without noticing that it is an irregular product, it is as follows. That is, as shown in FIG. 7B, when the irregular connector is pushed into the mating connector for the product number “C-100”, the identification protrusion 45 and the rib 43 are misaligned. In the middle of the fitting, the identification protrusion 45 cannot enter the rib housing groove 52, and the connector cannot be completely fitted by contacting the front surface of the hood 51. This makes it possible to recognize that the connector is an irregular product and reliably prevent the irregular product connector from flowing into the subsequent process.
[0023]
As described above, according to the connector of this embodiment, when the connector is not correctly molded by the mold 20, the rib 43 and the identification protrusion 45 are arranged so as to be shifted from each other in the connector fitting direction. Therefore, it is possible to easily determine that the product is an unauthorized product without requiring a complicated operation of reading the product number engraved for each connector. In addition, it can be easily confirmed whether or not the insert is correctly assembled in the mold body 21. In addition, when the irregular connector is assembled to the mating connector, either the misassembly preventing rib 43 or the identification protrusion 45 abuts against the end surface of the mating connector, so that the irregular connector is assembled incorrectly. Can be surely prevented.
[0024]
Second Embodiment
8A and 8B show two connectors 40X and 40Y having different product numbers according to the second embodiment of the present invention, and these are the configurations of the rib 43 and the identification protrusion 45. FIG. Only the connectors 40V and 40W of the first embodiment are different.
In the connectors 40X and 40Y of this embodiment, the ribs 43 form a pair and are arranged in the lateral direction of the one side surface 42A of the connector housing 42 and extend in parallel with the mating connector. In the connector 40X having the product number “C-101” shown in FIG. 8A, for example, both ribs 43 are arranged near both side edges of one side surface 42A of the connector housing 42, and the ribs 43, 43 are connected to each other. In the connector 40Y whose product number is “C-201” shown in FIG. 8B, for example, both ribs 43 are arranged near the center of one side surface 42A of the connector housing 42 and the ribs thereof are arranged. The interval between 43 and 43 is set narrow. The identification protrusions 45 are provided in pairs corresponding to the ribs 43. When the connectors 40X and 40Y are properly molded, the identification protrusions 45 are arranged on the same axis in the fitting direction of the ribs 43 and 43 and the connectors. Is set to be placed in
[0025]
Even in the configuration of this embodiment, as in the first embodiment, when the insert is mistakenly set in the mold body, the molded connector rib 43 and the identification protrusion 45 are fitted to the connector. The arrangement is shifted from each other in the matching direction, so that it is obvious and can be determined to be an irregular product. Thereby, it can be easily confirmed whether or not the insert is correctly assembled in the mold main body 21.
[0026]
<Third Embodiment>
One of the two connectors having different product numbers in the third embodiment is shown in FIG. 9, and the connector 40V, 40W of the first embodiment does not include the rib 43. Accordingly, the two connectors of this embodiment differ from each other only in the arrangement of the product number engraved in the product number display section 44 and the identification protrusion 45.
[0027]
Even when the connector does not include the rib 43 as described above, connectors having different product numbers can be easily distinguished by a simple operation of comparing the difference in position of the identification protrusion 45. Further, the difference in the position of the identification protrusion 45 can be easily recognized by a visual sensor or the like as compared with the difference in the product number engraved on the connector, so that the identification work between the connectors by the sensor can be automated. Become.
