Abstract

PURPOSE:To secure the insulating property between male pins and maintain the withstand load property of an opening in the extended portion of each of the male pins by having a pin mould which is formed through the process of moulding their plural male pins into a package in a case, and then installing each of protrusion-like partition boards in the case so as to be positioned between these plutal male pins respectively adjacent to one another. CONSTITUTION:The title device is constructed in such a manner that a pin mould 14 formed through the process of moulding plural male pins 13 into a package is provided in a case, and then each of protrusion-like partition boards 15 is installed in the case so as to be positioned between these plural male pins 13 respectively adjacent to one another. Since the protrusion-like partition board 15 is accordingly interposed between the two male pins 13 adjacent to each other, it may be prevented to have an effect on also the counterpart adjacent to one male pin 13 subjected to the effect even if foreign matter is entered from an opening. Besides, the protrusion-like partition board 15 may serve as a reinforcing material for higher strength against load on the case. Thus, the insulating property between the male pins 13 respectively adjacent to one another is sufficiently secured, and yet the device can be obtained with such construction as to have resistance to load given from above or from below.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a detachable connector for a controller part of an electric carpet or the like.

2. Description of the Related Art Conventionally, this type of connector has been disclosed, for example, in Japanese Patent Application Laid-Open No. 1430-1983.
As shown in Publication No. 14, it had a structure as shown in FIG. That is, when the pin mode μ mode 1 is set in the upper and lower cases 2 (only the lower case is shown in the drawing), there is a protruding partition plate from the case 2 on the extended part of the male pin 3. There was no opening at all, and there was only one large opening 4 in the case 2 at the part where the male pin 3 extended.

Problems to be Solved by the Invention However, with such a structure, it is difficult to attach the cord connector 5 as shown in FIG. If nine,
There is a foreshadowing that foreign matter is interposed between adjacent male pins 3, and if the foreign matter is conductive, a problem of poor insulation occurs. In addition, when such a connector is attached to a carpet and a load is applied from the top of the connector with the cord connector 5 removed from the male pin 3, a large opening 4 is formed in the extending portion of the male pin 3. A friend of mine had the problem of being weak in strength.

The present invention solves these problems by ensuring insulation between the male pins even if foreign matter gets in there, and also ensuring the load-bearing capacity of the opening of the male pin extension even when the cord connector is removed. The purpose is to maintain the

Means for Solving the Problems In order to solve the problems, the present invention includes a pin mold formed by molding a plurality of male pins inside a case, and also provides a protruding partition plate in the case, The partition plate is configured to be located between the plurality of male pins.

According to the present invention, a groove is provided in the base surface of the pin mold from which the male pin extends, and the inner end of the partition plate is fitted into this groove.

Function: With this configuration, a protruding partition plate is interposed between adjacent male pins, so even if a foreign object enters through the opening, it will not affect the adjacent male pin K.
Insulation can be ensured. In addition, by providing a groove in the pin mold and fitting the partition plate into the groove at a position deeper than the base of the male pin, the creepage insulation distance between adjacent male pins is increased, ensuring a sufficient insulation distance. In addition, the protruding partition plate serves as a strength reinforcing material against the load on the RS, and also serves as a guide plate when attaching the cord connector, thereby improving the ease of attachment.

Embodiments Hereinafter, embodiments of the present invention will be described based on the drawings.

First, a first embodiment shown in FIGS. 1 to 3 will be described.

In the figure, a pin mold 14 in which a plurality of male pins 13 are integrally protruded is housed inside an upper case 11 and a lower case 12 that are assembled together, as in the conventional example. A plurality of partition plates 15 are protruded from the lower case 12 so as to be located between the male pins 13. Also,
A print base 16 is provided inside the lower case 12, and the print base 16 and the pin mold 14 are connected to each other.
The print base 16 is connected to the print base 16 by a lead wire 17, and the end of a heat generating wire or a temperature detection wire provided on the carpet body 18 is connected to the print base 16. By the way, as shown in FIG. 1, the partition plate 15 is located between the respective male pins 13 of the pin mold 14, and is in contact with the surface of the base of the male pins 13 of the pin mold 14, which has a substantially rectangular parallelepiped shape. As a result, the adjacent male pins 13 are completely separated from each other from the root portion aVc.

FIG. 2 shows this connector installed in an electric carpet. The pin mold 14 and the print base 16 are set in the lower case 12, the upper case 11 is inserted from above the lower case 12, and the carpet body 18 is opened. Some are attached. 19 is a cord neck that can be attached and detached from the connector attached to the carpet body 18! A groove 20 is formed in this cord connector 19 in a shape and position corresponding to the partition plate 15 described above. In addition,
Cord connector 19 is connected to the main controller by cord 21.

Next, the operation of the configuration of this first embodiment will be explained.

As shown in FIG. 3, if a foreign object enters the opening 22 of this connector and adheres to the surface of the pin mold 14 near the base of the male pin B, the partition plate 15 prevents the foreign object from being trapped by other objects. It does not affect the male pin 13 at the location. That is,
If this foreign material n is conductive, the insulation distance between the adjacent male pins 13 would be insufficient if there was no partition plate 15, and if the cord connector 19i is used with the cord connector 19i installed, the insulation distance would be insufficient. Although there is a problem of causing defects, the presence of the partition plate 15 allows perfect insulation between adjacent male pins 13 to be maintained.

Next, regarding loads from the top or bottom surface,
Since the protruding partition plates 15 are arranged at relatively narrow intervals, the structure is very strong.

Furthermore, this partition plate 15 has a cord connector 19 (1
Since it corresponds in shape and arrangement to the groove portion 20 of No. 1, it can exhibit the effect of a guide plate when the cord connector 19 is attached to the connector.

In particular, by making the tip of the partition plate 15 longer than the tip of the male pin 13, or by increasing the thickness of the partition plate 15 in the center of the plurality of partition plates 15, the effect as a guide can be increased. Become.

Next, a second embodiment shown in FIGS. 4 and 5 will be described. In this second embodiment, a groove 24 into which the inner end of the partition plate 15 is fitted is formed in the pin mold 14, and the inner end of the partition plate 15 is fitted into the groove 24K.

The other configurations are the same as those of the first embodiment. With this configuration, the creepage insulation distance between the root parts of the nine adjacent male pins 13 and the male pins 13 is the linear distance between the root parts of the male pins 13 in the first embodiment, whereas in the second embodiment In the example, the distance along the groove 24 of the pin mold 14 is also added, so
This means that the insulation distance has increased significantly. Since the pin mold 14 and the partition plate 15 come into contact with each other with the plate inserted into the groove 24, there is no possibility that the foreign object 23 will be caught between the pin mold 14 and the partition plate 15.

Also from this point of view, sufficient insulation between adjacent male pins 13 can be ensured.

Effects of the Invention As described above, according to the present invention, since the space between adjacent male pins is partitioned by a partition plate, insulation can be ensured, and foreign objects can be prevented from entering through the opening of the connector. Even if it adheres to the pin part, the insulation distance m between it and other male pins can be ensured, and there is no problem in terms of insulation performance. Also, the presence of nine partition plates between each male pin provides a structure that is resistant to loads from above or below. Accordingly, the wall thickness of the case can be made thinner than that without the partition plate.

Furthermore, since the partition plate serves as a guide when the cord connector is attached, there is also the advantage that attachment ease is improved.

In addition, by providing a groove in the pin mold and fitting the partition plate into the groove at a position deeper than the base of the male pin, the creepage insulation distance between adjacent male pins becomes longer, ensuring a sufficient insulation distance. Can be secured.

Moreover, the present invention can be expected to have the effect of being compatible with models such as electric carpets while maintaining a common structure using partition plates. That is, when the product size or rating value of an electric carpet or the like differs, it is necessary to change some of the circuit constants of the main controller connected to the cord connector. Therefore, it is not possible to use the same connector for all of these models, but the circuit configuration is generally the same, so when you want to standardize the design as much as possible, the easiest way to deal with different models is to use a partition plate. By changing the thickness or changing the position, most parts can be made into a common design. In this way, the connector according to the present invention can be easily adapted to different models.
