Description

PCB connector structure with insert-in dip angle and easy installation Technical Field The invention belongs to the technical field of connectors, and particularly relates to a PCB connector structure with an inserting inclination angle and easy installation. Background The electrical connector is widely used in various fields of communication, industry, traffic, etc., and meanwhile, requires quick and reliable connection between the plug and the socket. When the electric connector is applied to the cabinet, in order to realize quick connection of a PCB (printed circuit board) in the cabinet and a power supply outside the cabinet, a PCB socket is plugged with the PCB in the cabinet, then a square disk socket is plugged with the PCB socket, the square disk socket is penetrated and fixed on a panel of the cabinet, then a plug connected with the power supply outside the cabinet is plugged with the square disk socket, and the structure of the two-type connector (the PCB socket and the square disk socket are separately arranged) not only can quickly transmit the power supply outside the cabinet to the PCB in the cabinet, but also is convenient for automatic production and assembly of the PCB end, so that the electric connector is widely applied to the field of communication. In the existing two-body type connector structure, the PCB socket and the square disc socket can only be horizontally inserted, when special requirements in actual production are met, the PCB socket is required to be inserted with the square disc socket at a certain angle in a deviating mode, and then the plug and the square disc socket are inserted at a certain angle so as to adapt to the space position of each device in the actual production, and the existing two-body type connector structure cannot be inserted at a certain angle in a deviating mode. In PCB sockets, including an insulator, a contact, the insulator typically includes an insulator housing, an insulator cover, and the contact is secured within the insulator housing using an insulator cover cap to secure the contact within the insulator housing. The contact piece needs to be buckled and fixed by an upper nonmetallic piece and a lower nonmetallic piece (an insulator shell and an insulator cover plate), the structure is complex, and the installation process needs at least two steps. In summary, the existing PCB socket has a single plugging direction, cannot meet plugging deviating from a certain angle, has a complex structure and high processing cost, and is complex to install, so that the application of the PCB socket is not wide enough. Disclosure of Invention In order to solve the technical problems of single plugging direction and complex structure of the PCB socket, the invention provides a PCB connector structure with plugging dip angle and easy installation. The aim of the invention is realized by adopting the following technical scheme. The PCB connector structure with the plugging inclination angle and easy to install comprises an insulator and a contact piece, wherein the insulator is integrally provided with a blind hole for plugging the contact piece, a jack structure of the contact piece is obliquely arranged, a cavity matched with the jack structure is arranged in the blind hole, an inclined surface perpendicular to the axis of the jack structure is arranged outside the insulator, a jack communicated with the cavity in the insulator is vertically arranged on the inclined surface, and the plugging end of the jack structure is aligned and matched with the jack on the insulator. Further, a protruding structure for wrapping the jack structure is arranged at a position, close to the jack structure, outside the insulator. Further, the end face, located on the same side with the protruding structure, of the insulator is a horizontal plane for providing space for grabbing mechanical equipment. Further, the plug-in end of the plug-in hole structure comprises a plurality of jack spring pieces which encircle to form plug-in holes, the jack spring pieces are of a cantilever structure, and after the contact is plugged in, a fit gap which is formed by outwards expanding the jack spring pieces is reserved between the inner wall of a cavity matched with the plug-in hole structure and the outer wall of the plug-in end of the plug-in hole structure. Further, a pair of connecting plates which are parallel to each other are arranged at the rear end part of the jack structure towards the outer side part of the opening of the blind hole, and straight grooves for inserting and limiting the connecting plates are formed in the insulator. Further, after the contact is inserted in place, the end part of the connecting plate, which is close to the inner side of the blind hole, is propped against the bottom of the straight groove, and an upper fixing platform for limiting the inner side of the connecting plate is formed at the bottom of the straight groove. Furthermore, the connecting plates a
