Description

Electrical connector, and manufacturing method of electrical connector

The present invention provides an electrical connector having a plate-shaped contact support portion that can support a contact and is inserted and removed from an opposite side connection portion in an insulating case.

In a conventional electrical connector, it is known that a plate-shaped contact support portion that inserts and removes a support contact and is connected to and removed from an opposite side is provided in an insulative housing, and contacts are arranged on the upper and lower sides of the contact support portion. Make it multi-polarized. This electrical connector has a plate shape and holds the metal plate at the contact support portion for the contact support portion having a low strength (for example, Patent Document 1).

The above metal plate is embedded and fixed to the contact support portion by being integrally formed with the casing. Specifically, by filling the melted resin into the cavity formed by the upper mold and the lower mold, a state in which the metal plate is sandwiched from above and below by the fastening pin is formed, so that the metal plate combined with the mold is not formed. The molten resin is filled into the cavity away from the predetermined position. After the temperature of the resin is lowered to harden the resin, the metal plate and the contact support portion of the casing are integrally molded and fixed by the removal of the fastening pin. And, by pressing the contacts into the casing and fixing them, a part of the contacts is exposed and arranged on the outer surface of the contact support portion of the casing.

However, in the conventional electrical connector, when the metal plate and the contact support portion of the housing are integrally formed and fixed, since the fastening pin is used to sandwich the metal plate up and down, after the fastening pin is removed, There is a space between the metal plate fixed by the contact support portion and the contact provided on the surface of the exposed contact support portion. This space may cause electrical problems due to the presence of foreign matter or liquid, which is a problem to be solved. Question. In particular, due to the temperature change around the electrical connector, moisture in the air in the space between the metal plate and the joint is condensed, so that there is a possibility that electric water is generated in the space between the metal plate and the joint. Sex. Further, although the longer the distance between the metal plate and the contact is considered, the incidence of the above electrical problem is reduced, but at this time, there is a problem that the size and density of the electrical connector are difficult.

SUMMARY OF THE INVENTION An object of the present invention is to provide an electrical connector capable of preventing electrical problems even when a space between a metal plate and a contact exists in the presence of a foreign matter or a liquid, and achieving miniaturization and high electrical connector Densification. Moreover, from another point of view, the freedom of design of such an electrical connector can be improved.

An electrical connector according to the present invention includes: an insulating case provided with a plate-shaped contact supporting portion that is extended from a rear wall to a front side and an opposite side connector; and is provided in the contact supporting portion a connecting portion of the outer surface; and a terminal portion that connects the conductive portion of the substrate, and has a conductive contact held by the case, and is separated from the connecting portion and fixed to the connecting portion in a thickness direction of the contact supporting portion a metal plate of the contact support portion, wherein at least a portion of the metal plate includes an insulating portion, and the contact support portion has at least a portion extending in the thickness direction and at one end of the plate thickness direction The opening is formed on the outer surface of the contact support portion, and the insulating portion is exposed at the other end portion in the thickness direction, but the hole portion of the metal plate is not exposed.

At least a portion of one end portion in the thickness direction of the hole portion is opened to the outer surface of the contact support portion, and the other end portion of the hole portion in the thickness direction is exposed to the insulating portion but does not expose the metal plate even if the contact portion When the moisture in the air in the hole portion of the support portion is condensed or the like is retained, or when the hole portion of the contact support portion is mixed with foreign matter, or when the distance between the metal plate and the connection portion in the hole portion is short, The metal plate and the connecting portion are prevented from being electrically connected via a liquid or a foreign matter.

In addition, since one of the end portions of the hole portion has an opening, in other words, since the connection portion of the connector does not need to completely close the hole portion, the position or size of the hole portion can be arbitrarily determined, thereby Compared with the aspect of the closed hole portion, the degree of freedom in designing the hole portion can be improved. Therefore, with the miniaturization of the electrical connector, even if the distance between the connection portions of the connector is narrowed, the hole portion can be appropriately disposed.

A method of manufacturing an electrical connector according to the present invention is the manufacture of an electrical connector comprising: a plate-shaped contact support insulating case extending from a rear wall to a front side and fitted to an opposite side connector a connecting portion provided on the outer surface of the contact supporting portion, a terminal portion connecting the conductive portion of the substrate, and a conductive contact held by the casing; and the connection in the thickness direction of the contact supporting portion a metal plate that is separated and fixed to the contact support portion; and the manufacturing method includes the steps of: forming an insulating portion on at least a portion of the metal plate; a step of assembling the metal plate into the film cavity of the mold; by arranging the fastening pin at least a portion and not covering the range provided by the connecting portion, clamping the surface of the metal plate to form the insulating portion And a step of holding the resin into the mold and forming the outer casing integrally with the metal plate; forming the outer surface from the outer surface of the contact support portion to the insulating portion The step of the hole section.

For example, when manufacturing an electrical connector in which the hole portion is completely closed by the connecting portion, it is necessary to use a fastening pin having a width smaller than the width of the connecting portion, so that the width of the formed hole portion is larger than the width of the connecting portion. narrow. In this case, with the miniaturization of the electrical connector, when the width of the connection portion of the contact is reduced, the width of the fastening pin must be reduced correspondingly, and it is impossible to secure the fastening pin for holding the metal plate. The possibility of sufficient strength. According to the present invention, if at least a part of the fastening pin does not overlap with the range in which the connecting portion is provided, a wide-width fastening pin having a wider width than the connecting portion can be used, so that a necessary fastening pin can be obtained. The degree of freedom in the design of the intensity.

According to the present invention, even if foreign matter or liquid is present in the space between the metal plate and the contact, electrical problems can be prevented, and miniaturization and high density can be achieved. In addition, the design freedom of such an electrical connector can be improved.
