Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-voltage connector having a structure capable of ensuring a creepage distance and a space distance for improving withstand voltage.

[0002]

2. Description of the Related Art Conventionally, in a connector having a pin header accommodating a plurality of pin contacts, in order to secure a creepage distance and a space distance for improving withstand voltage, it is necessary to increase a pitch interval of the pin contacts. I was doing.

[0003]

However, if the pitch spacing of the pin contacts is set large in order to secure the creepage distance and the clearance, the size of the pin header must be increased, and the connector as a whole is It becomes larger. For this reason, a large space is required in the device for accommodating the connector, which is against the demand for miniaturization of the device.

The present invention has been proposed in view of the problems of the prior art as described above, and secures a substantial creepage / space distance between the pin contacts without increasing the size of the connector, thereby improving the withstand voltage. An object of the present invention is to provide a high voltage connector that can be increased.

[0005]

In order to solve the above-mentioned problems, a high-voltage connector according to the present invention has a pin header made of an insulating material for accommodating a plurality of pin contacts, and an insertion connecting portion for the pin contacts. The pin header comprises a socket housing having a holding portion for holding the socket contact, and the pin header has a partition wall made of an insulator between adjacent pin contacts.
An independent receiving portion is formed for each book, and the holding portion of the socket contact in the socket housing is formed to be insertable into the receiving portion.

Further, the rear end sides of the pin contacts are fixedly inserted so as to project rearward from the pin headers, respectively, and the partition wall is rearwardly arranged from the pin headers so as to be interposed over the entire length between the adjacent pin contacts. It is formed to project.

Further, the rear end sides of the pin contacts are each bent into an L shape so that they can be connected to a substrate on which the pin header is to be mounted, and the partition wall has a downward projecting portion. It can be inserted into the slit provided in the.

[0008]

In the high-voltage connector according to the present invention, the plurality of pin contacts of the pin header to be inserted into the board secure the creeping and spatial distances from the receiving portion to the board by the partition wall made of an insulator. In addition, the holding part of the socket housing that is fitted and connected to the receiving part of the pin header is divided so as to be separated by the space, and when the fitting connection is made to the pin header of the socket housing, part of the partition wall of the pin header is It enters the space of the housing.

[0009]

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. As shown in FIGS. 1 to 3, the high-voltage connector according to the present invention includes a substrate 1
The pin header 3 is fixedly held in (FIG. 3), and the socket housing 5 is fitted and connected to the pin header 3.

The pin header 3 has a pin contact 31.
a and 31b are inserted and fixed in parallel at a predetermined interval. The tip ends of the pin contacts 31a and 31b are located in the receiving portions 33a and 33b that receive the fitting portions 53a and 53b of the socket housing 5. This receiving part 33
The a and 33b are separated by a partition wall 35 formed integrally with the pin header 3. The partition wall 35 has an external partition wall portion 35a protruding rearward of the pin header 3 and a lower partition wall portion 35b protruding downward. As a result, the outer partition wall portion 35a isolates the pin contacts 31a and 31b up to the terminal end portion, and the lower partition wall portion 35b forms the substrate 1 as shown in FIG.
It is inserted into the slit 11 formed in. The rear end sides of the pin contacts 31a and 31b are bent downward in an L shape, and when the pin header 3 is inserted into the board 1, the bent portions come into contact with the surface of the board 1 so that electrical connection by soldering or the like can be performed. Has been The outer partition wall portion 35a and the lower partition wall portion 35b may be integrated with the partition wall 35,
Therefore, it may be formed separately and subsequently connected to the pin header 3.

Fitting portions 53a, 5 of the socket housing 5
Since 3b is for fixing and holding the socket contact 51a (only one is shown) into which the pin contacts 31a, 31b are inserted and connected, it may be called a holding portion. The fitting portions 53a and 53b are the receiving portions 3 of the pin header 3.
3a and 33b are fitted and connected. This fitting portion 53a,
53b is divided and formed corresponding to the receiving parts 31a and 31b. Further, a partition wall 55 separates the fitting portions 53a and 53b from the rear end side. That is, the pin contacts 31a and 31b are separated from each other on the connection side with the socket contact 51a.
a, 53b and the partition wall 35, and on the rear end side by the external partition wall portion 35a, both pin contacts 31 are formed.
The state where a and 31b are shielded is substantially the same as the state where the creeping surface and the spatial distance are secured.

In FIG. 4, two pin contacts 31a,
It is understood that the creepage distances and the space distances of the front end side and the rear end side of 31b are indicated by broken lines and the spatial distances are indicated by alternate long and short dash lines, respectively, and that both distances are sufficiently secured by the partition wall 55.

In the above description, the number of pin contacts is two, but the present invention is not limited to this, and it goes without saying that the present invention can be applied to a connector having three or more pin contacts.

[0014]

As described above, according to the connector of the present invention, the socket contact of the socket housing is fixedly held in the divided fitting portion, and the fitting portion receives the pin header separated by the partition wall. In addition, at the end of the pin header on the board ground side, the lower partition wall extends to enter the board, so the pin contacts are arranged in parallel without a large pitch interval. It is possible to secure a creepage distance and a space distance between the pin contacts, effectively prevent voltage interference between the pin contacts, and reduce the size of the connector, and thus the size of the device equipped with the connector.
