Description

Technical Field

[0001] The present application relates to the technical field of connectors, and in particular to a connector that is easy to assemble. Background Art

[0002] As a key component, connectors play an important role in connecting two active devices and transmitting current or signals. They are widely used in transportation, communications, networks, information technology (IT), medical treatment, home appliances and other industries. The rapid progress of product technology in these supporting fields and the sharp increase in market demand have provided a strong driving force for the development of connector technology.

[0003] In the prior art system, the connector is usually composed of a male plug and a female socket that are plugged into each other, and the two are electrically connected through multiple signal connection lines. The two ends of these signal connection lines are respectively connected to the back side of the male plug, and the key to the connection lies in the processing of the ends of the signal connection lines. Specifically, after the insulation layer of the signal connection line is stripped at the end, it will be fixedly connected to the metal terminal. At the same time, a special fixing groove is designed on the back side of the male plug to accommodate and fix these metal terminals.

[0004] However, in the process of connecting the metal terminal at the end of the signal connection line with the fixing groove, multiple metal terminals need to be inserted into the corresponding fixing groove one by one and accurately. This step not only requires the operator to be highly careful and patient, but also needs to ensure that the metal terminal is perfectly aligned with the fixing groove to avoid any possible misalignment. However, such an operation process is cumbersome and time-consuming, which greatly affects the assembly efficiency of the connector and there is room for improvement. Summary of the invention

[0005] The purpose of the present application is to provide a connector that is easy to assemble, so as to solve the problem that the plugging process of the metal terminal and the fixing groove in the above-mentioned related art is relatively cumbersome and inefficient.

[0006] The present application provides a connector that is easy to assemble and adopts the following technical solution: A connector that is easy to assemble, including a plug body and a flat flexible cable, wherein the flat flexible cable includes a plurality of flat copper wires arranged side by side and a protective sleeve covering the outside of all the flat copper wires; a connecting terminal connected to the internal flat copper wire is fixedly provided at the end of the protective sleeve, and a connecting groove for the connecting terminal to be embedded and fixed is opened on the plug body, and the flat copper wires and the connecting terminals correspond to each other and are the same in number.

[0007] By adopting the above technical solution, when the flat flexible cable is assembled with the plug body, after the connecting terminals are fixed on the flat flexible cable, due to the integrated setting of the flat flexible cable, all the connecting terminals on the flat flexible cable can be inserted into the corresponding connecting grooves at the same time, thereby reducing the corresponding assembly time and improving the overall assembly efficiency of the connector.

[0008] Optionally, the connecting terminal is symmetrically provided with protruding teeth penetrating the protective sleeve and the flat copper wire; the penetrating portion of the protruding teeth can be bent and fit with the surface of the protective sleeve.

[0009] By adopting the above technical solution, when the connecting terminal and the flat flexible cable are assembled, due to the setting of the protruding teeth, the protruding teeth are inserted into and penetrate the overlapping part of the protective sleeve and the flat copper wire, and then the two relative protruding teeth are bent in a direction close to each other using a tool, thereby improving the assembly stability of the corresponding connecting terminal and the flat flexible cable and reducing the possibility of loosening of the connection between the connecting terminal and the flat flexible cable.

[0010] Optionally, a fixing sleeve is provided on one side of the plug body, and a recessed groove is provided on an opening edge of one side of the fixing sleeve; the end of the plug body close to the connecting groove can be inserted into the recessed groove, and the connecting terminal is inserted into the connecting groove after passing through the fixing sleeve; an elastic sheet that can be tightly pressed against the outer side of the protective sleeve is fixedly provided on the side edge of the fixing sleeve away from the plug body; a contact block is fixedly provided on the side of the elastic sheet close to the protective sleeve.

[0011] By adopting the above technical solution, the end of the plug body close to the connection groove is inserted and fixed into the recessed groove in advance, and then the connection terminal on the protective sleeve is inserted into the connection groove after passing through the fixing sleeve. Due to the setting of the fixing sleeve and the elastic sheet, the elastic sheet can be pressed against the outer surface of the protective sleeve, thereby further improving the assembly stability of the flat flexible cable and the plug body; Optionally, a pressing rod and an adjusting rod are provided on the outside of the fixed sleeve, and a pressing hole for inserting the pressing rod is opened on the fixed sleeve, and a pressing plate is fixed to the end of the pressing rod away from the fixed sleeve; the end of the adjusting rod close to the pressing rod is hinged to the edge of the pressing plate, and the other end of the adjusting rod is hinged to the end of the elastic sheet away from the fixed sleeve, and the pressing rod drives the elastic sheet to bend when it moves in the direction away from the fixed sleeve, and drives the elastic sheet to fit with the protective sleeve when it is pressed in the direction close to the fixed sleeve.

[0012] By adopting the above technical solution, when force is applied to the pressing plate to move the pressing rod away from the fixed sleeve, the elastic sheet will be driven to bend outward. This state makes it easy to install the connecting terminal inside the connecting groove along the inclined surface of the bent elastic sheet. When the connecting terminal and the plug body are installed, the pressing rod is pressed in the direction close to the fixed sleeve. At this time, the bent elastic sheet is reset, so that one side of the elastic sheet is in contact with the outer side of the protective sleeve, thereby improving the assembly stability of the flat flexible cable and the plug body.

[0017] Optionally, an elastic locking pad is fixedly provided on the side of the locking block away from the pressing rod.

[0018] By adopting the above technical solution, when the locking block protrudes from the limiting groove, due to the provision of the elastic pressing pad, the locking block can enhance the stability of pressing against the outside of the protective sleeve inserted into the connecting groove.

[0019] Optionally, the pressing plate is larger than the cross-sectional size of the pressing rod, and a positioning recess for the pressing plate to be inserted is provided on the opening edge of the pressing hole.

[0020] By adopting the above technical solution, during the pressing process of the pressing rod, due to the coordinated setting of the pressing plate and the positioning groove, the user can control the corresponding pressing rod to be pressed down synchronously by pressing the pressing plate until the lower edge of the pressing block is inserted into the positioning groove, thereby limiting the downward stroke of the pressing rod through the positioning groove.

[0021] Optionally, the ends of several pressing rods on the same side of the fixing sleeve are fixedly connected to the same pressing plate.
