Description

Electrical connector capable of reducing signal loss

This creation relates to an electrical connector, particularly an electrical connector capable of reducing signal loss.

For high-frequency (such as RF) or even high-frequency and high-signal strength wired signal transmission, coaxial cable is a generally accepted wired signal transmission method. In order to meet the needs of the system, the coaxial cable may have to be connected through multiple sections. At this time, each section of the coaxial cable is connected through two mating connectors. The connection between the two connectors and the coaxial cable is generally through male and female connectors, which is also convenient for disassembly, that is, one of the connectors has a male and female connector. A male connector or a female connector is provided, and a female connector or a male connector is provided at one end of the coaxial cable. Through the connection of the male and female connectors, the coaxial cable is connected to the connector; similarly, another connector is provided with a female connector or a male connector, and another section of the coaxial cable is provided with a male connector or a female connector at one end to connect with the female connector or the male connector of the connector. In this way, the above two connectors realize the connection of the two sections of coaxial cable through the connection of the male and female connectors thereon. However, the above connection method increases two sections of impedance and causes obvious signal attenuation because the two connectors are connected to the coaxial cable with male and female connectors respectively. Therefore, how to minimize signal loss without affecting the user interface is a topic that continues to attract attention in this field.

Based on the above, the main purpose of this invention is to provide an electrical connector that can reduce signal loss, mainly to allow the coaxial cable to be directly connected to the terminal head for docking, and to be directly fixed to the connector through the terminal head. When the connector is docked with another connector, the terminal heads of the two are directly connected. In this way, a connection interface between the connector and the coaxial cable can be omitted, thereby significantly reducing impedance and signal loss.

A major technical means adopted to achieve the above-mentioned purpose is to make the above-mentioned electrical connector capable of reducing signal loss include a connector; the connector includes: an outer shell, which is hollow, a front mounting plate and a rear mounting plate are arranged inside the outer shell, a mounting slot is formed between the front mounting plate and the rear mounting plate, a plurality of through holes are formed on the front mounting plate and the rear mounting plate, and the through holes on the front mounting plate can correspond to the through holes on the rear mounting plate; a cable module, mainly in a fixed card A plurality of cable terminals are detachably provided on the fixing clamping assembly; wherein the fixing clamping assembly is detachably provided in the mounting groove in a matching shape, and the fixing clamping assembly has a plurality of clamping holes; each cable terminal has a terminal head and a coaxial cable, the terminal head has a butt end and a connection end, the butt end is inserted into the plurality of clamping holes of the fixing clamping assembly and the plurality of through holes on the front mounting plate and the rear mounting plate, and the connection end is connected with the coaxial cable.

Preferably, the fixed clamping assembly is mainly composed of a fixed clamping part and a movable clamping part, the fixed clamping part is formed with a plurality of fixed clamping holes, the movable clamping part is formed with a plurality of extended clamping holes, each fixed clamping hole can correspond to each extended clamping hole, the fixed clamping hole and the corresponding extended clamping hole together form the clamping hole for the terminal head of each cable terminal to pass through, the terminal head of each cable terminal passes through the corresponding through hole on the front mounting plate, and the coaxial cable of each cable terminal passes through the corresponding through hole on the rear mounting plate.

Preferably, one or more wedges are formed on the inner side of the outer shell, and the front mounting plate and the rear mounting plate are engaged with the wedges.

Preferably, a male slot is provided at the top of the housing between the front mounting plate and the rear mounting plate to connect the mounting slot to the outside of the housing, and the cable module can be installed in the mounting slot via the male slot.

Preferably, the housing is also provided with at least one screw hole, through which a screw can be inserted into the mounting groove and exert a thrust on the movable engaging member.

Preferably, the fixed engaging member has an elastic sheet fixed side edge on which at least one elastic sheet is provided, and an elastic side edge of the movable engaging member is against the elastic sheet and bears its elastic force.

Preferably, when a moving side edge of the moving engaging member is pushed to an insertion position, the terminal head of each cable terminal can be inserted into the engaging hole, wherein the moving side edge and the elastic sheet fixed side edge are the opposite side edges of the moving engaging member.

Preferably, when the movable side edge of the movable engaging member is pushed to a locking position, the terminal head of each cable terminal is locked in the locking hole by both the corresponding fixed locking hole and the extended locking hole.

From the above, it can be seen that the connector of this invention is used to connect the coaxial cable in such a way that the coaxial cable is directly connected to the terminal head for docking, and the terminal head is directly fixed on the connector. When it is connected to another section of coaxial cable through another connector, the terminal heads on the two connectors are directly connected, thereby eliminating the connection interface between the coaxial cable and the connector, effectively reducing impedance and avoiding signal loss.
