Description

Inclined waterproof connector

The present invention relates to an electrical connector, particularly a slantable waterproof connector that has a waterproof function and can be inserted and removed in a direction of oblique insertion angle.

Although the types of electrical connectors are known to be numerous, most of the electrical connectors are basically composed of male and female connectors that can be plugged and coupled to each other.

It is known that electrical connectors may have one or several electrical connection terminals for transmitting power, electrical signals or both depending on different purposes; in order to increase the reliability and safety level of the electrical connector, pull-proof, dust-proof and The waterproof function is also a common basic requirement; for example, the Republic of China new patent M315444 "Improved construction of the cable connector" has been approved, and the male connector is locked to the female connector by a locking nut. In the Republic of China new patent M328109 "Power Connector Quick Positioning Structure", which has been approved for announcement, it discloses a quick positioning structure of the power connector. The speed of the quick positioning structure is faster than that of the aforementioned locking nut. In addition, in the Republic of China new patent M395951 "joint device" which has been approved for publication, there is disclosed a connector device which can be mounted on an electronic device for receiving and protecting the connector connector of the mutual plug connector, and the aforementioned conventional electrical connection. Compared to the structure, the structure is obviously more complicated.

Although electrical connectors of different uses or functions usually have slight differences in structural design, such as having different waterproof or dustproof structures, most of the known electrical connectors are designed for linear plugging, in other words, electrical connections. Both the male connector and the female connector It can only be inserted and removed in the coaxial straight direction. This kind of electrical connector that can only be used for linear plugging and unplugging operation will not be used in some special applications, for example, when applied to some electric vehicles. The male connector cannot be linearly inserted into the female connector due to the mounting position of the electrical connector or by the blockage of certain locomotive structures or components. Therefore, it is necessary to develop an electrical connector that can solve the above problems and has a waterproof function.

As an embodiment of the novel slantable waterproof electrical connector, the female terminal block has a guiding notch for guiding the first male terminal into the corresponding first female terminal.

In an embodiment of the present invention, the male connector includes at least one second male terminal, and the female connector includes at least one second female terminal corresponding to the second male terminal, the second female The terminal is disposed on the female end housing and aligned with the second male terminal, wherein the second female terminal is in contact with the second male terminal to form an electrical connection for transmitting power or an electrical signal.

As an embodiment of the novel slantable waterproof electrical connector, the second male terminal is an elastically extendable terminal.

As an embodiment of the novel slantable waterproof electrical connector, wherein the second male terminal and the corresponding second female terminal are a type of pin type terminal.

The utility model has the advantages that the male connector and the female connector can be inserted and removed in the direction of the oblique insertion angle, and the male connector is pushed in the same axial direction as the female connector. After the coupling position, the waterproof gasket can provide a tight waterproof effect between the insertion portion of the male connector and the recess of the female connector, which can solve the problem that the male connector cannot be linearly inserted into the female in some applications. The end connector is a problem and provides a waterproof function.
