Description

Technical Field

[0001] The utility model relates to the technology in the field of connectors, in particular to a vertical male connector for preventing short circuit. Background Art

[0002] A connector is also called a coupler. In China, it is also called a connector and a socket, generally referring to an electrical connector. That is, a device connecting two active devices, transmitting current or signals. After the male end and the female end are in contact, they can transmit information or current, and are also called connectors. Connectors are widely used in electronic devices to achieve electrical connection of internal electrical components. With the continuous development of electronic technology, their application scope is becoming more and more extensive. Whether it is equipment used in industrial production or mobile phones, computers, MP3s, etc. that people often use, connectors play an indispensable and important role.

[0003] The BTB connector is a kind of connector that is widely used. The BTB connector is a component used to connect different circuit boards in an electronic device. Its main function is to provide a reliable electrical connection, allowing signals, power or data to be transmitted between one circuit board and another. Most of the power terminals of the existing BTB connectors are arranged outside the insulating body, which is easy to contact with external metals and cause short circuits, and is also easy to be deformed and damaged by external collisions, shortening the service life. At the same time, its power terminals lack elasticity. When plugging, the force received by the power terminal directly acts on the pad of the circuit board from the welding part. After repeated plugging, the welding between the welding part and the pad will become unstable, causing the connector to fall off the circuit board. Therefore, it is necessary to improve the existing BTB connectors. Content of the Utility Model

[0004] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide a vertical male connector for preventing short circuit, which can effectively solve the problems that the power terminals of the existing BTB connectors are arranged outside the insulating body, are easy to contact with external metals and cause short circuits, and the connectors are easy to fall off the circuit board.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] As a preferred solution, a limiting groove is provided in the insulating body, a limiting portion extends outward from the rear end of the power contact portion, and the limiting portion is inserted into the limiting groove for limiting.

[0008] As a preferred solution, an empty groove is provided at the upper opening of the plugging cavity, the signal terminal group is arranged close to the empty groove, the power contact portion is higher than the signal terminal group, during plugging, the female seat first contacts and conducts with the power terminal, and then contacts and conducts with the signal terminal group, effectively avoiding unnecessary miscontact of terminals of different natures between the male head and the female seat during the plugging process.

[0009] As a preferred solution, a strip-shaped groove is provided at the upper end of the power contact portion, and the strip-shaped groove extends up and down. This design makes the conduction between the power contact portion of the power terminal and the power contact portion of the female seat no longer a traditional point contact. Instead, it makes the power contact portion of the power terminal and the power contact portion of the female seat form two or more point contacts, effectively reducing the resistance of the power terminal.

[0010] As a preferred solution, a plurality of signal terminal grooves are provided on the front and rear wall surfaces in the plugging cavity, the signal terminal group includes a plurality of signal terminals, and the plurality of signal terminals are arranged in the corresponding signal terminal grooves.

[0011] As a preferred solution, two power terminal grooves are provided on the front and rear wall surfaces in the plugging cavity, and every two power terminal grooves are respectively located on the left and right sides of the front and rear inner walls of the plugging cavity. The aforementioned plurality of signal terminal grooves are arranged between the corresponding two power terminal grooves. Correspondingly, there are four power terminals, and each power terminal is arranged in the corresponding power terminal groove.

[0012] As a preferred solution, the multiple signal terminals each include a signal contact portion, a signal main body portion, and a signal welding portion that are integrally formed in sequence. The signal contact portion is located in the insertion cavity. The signal main body portion includes a signal bending section and a signal parallel section that are integrally formed and connected. This design enables the signal terminal to have a certain elasticity. The signal bending section is bent forward or backward at the rear end of the signal contact portion. The signal parallel section extends downward by bending at the rear end of the signal bending section. The signal welding portion extends forward or backward by bending at the rear end of the signal parallel section.

[0013] As a preferred solution, it further includes a circuit board. The circuit board has a power supply pad and a signal pad. The insulating body is arranged on the circuit board. The power supply welding portion is welded to the power supply pad, and the signal welding portion is welded to the signal pad.

[0014] As a preferred solution, two positioning posts extend out from the lower side of the insulating body. The two positioning posts are arranged diagonally on the lower side surface of the insulating body. Two positioning holes are formed on the circuit board. The aforementioned two positioning posts are respectively inserted into the corresponding positioning holes for positioning. The diagonal arrangement design makes the positioning more accurate and reliable.

[0015] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

[0016] By arranging the power supply terminal in the insertion cavity, it is difficult for it to come into contact with external metals, avoiding short circuits of the connector, and the power supply terminal is not easily deformed due to external collisions, effectively extending the service life of the connector. Coupled with the power supply bending section being bent forward or backward at the rear end of the power supply contact portion, the power supply bending section provides elasticity for the power supply terminal. During insertion, part of the force on the power supply terminal can be offset, effectively weakening the force on the welding portion and the pad, making the assembly of the connector and the circuit board more firm and reliable, and the connector will not fall off the circuit board.

[0017] Most of the power supply terminals of existing BTB connectors are arranged outside the insulating body, which is easy to come into contact with external metals, resulting in short circuits, and is also easily deformed and damaged due to external collisions, shortening the service life. At the same time, its power supply terminal lacks elasticity. During insertion, after the power supply terminal is stressed, the force directly acts on the pad of the circuit board from the welding portion. After repeated insertions, the welding between the welding portion and the pad becomes unstable, causing the connector to fall off the circuit board. Therefore, it is necessary to improve the existing BTB connectors.
