Description

Technical Field

[0001] The invention relates to the technical field of electronic equipment connection, and in particular to a pin connector. Background Art

[0002] An electrical connector is an electronic component that uses a mechanical structure to achieve circuit conduction and disconnection. Its core function is to establish a reliable electrical signal transmission channel between devices, components or systems while allowing physical separation and repeated plug-in and unplug operations.

[0003] As for the existing electrical connectors, whether they are long pins or short pins, there is a gap between the socket body and the pin when the pin is connected to the socket body, resulting in a different position of each pin in the hole. This causes the pin end to be unable to align with other docking parts when connected to other docking parts, which leads to problems such as failure to connect or bending and damage of the pin, increasing the manufacturing cost. Moreover, most of the pins are made of metal. When power is turned on, a magnetic field will be generated on the pin, and most of the existing equipment pins have no partitions, which causes the magnetic fields to affect each other, which will affect the transmission of data and damage to the equipment, and cross-flow is prone to occur.

[0004] Therefore, how to provide a pin connector to solve the defects existing in the existing electrical connector structure is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0022] In a possible implementation, the insert includes:

[0023] The T-shaped block has a plurality of extension pieces arranged on the front and rear surfaces of the upper end;

[0024] Plugs, provided in pairs, are mounted on the bottom of the T-block.

DETAILED DESCRIPTION

[0049] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Please refer to Figure 1-Figure 12 Now, a pin connector disclosed in the present invention is described. The present invention consists of six parts, such as Figure 1-Figure 2, including a plug 1, a short pin 2, a long pin 3, a spacer block 4, a socket body 5 and a limit block 6. The plug 1 is inserted on the left and right sides of the socket body 5, the long pin 3 is inserted at the front end of the socket body 5, the short pin 2 is inserted at the front end of the socket body 5, the short pin 2 is arranged below the long pin 3, the short pin 2 and the long pin 3 are arranged at intervals, the spacer block 4 is arranged between two short pins 2 or two long pins 3, and the limit block 6 is installed on the top of the short pin 2 and the long pin 3.

[0051] When the present invention is in use, the two plug-ins 1 are first inserted into the connecting hole 59. During the insertion, the extension piece 12 abuts against the front and rear side walls of the upper half of the connecting hole 59, so as to limit the position of the plug-in piece 1. Then, the long pin 3 and the short pin 2 are respectively inserted into the corresponding rectangular block 54. Then, the design of the limiting block 6 is used to make the height of the limiting block 6 plus the short pin 2 or the long pin 3 just the same as the height of the plug hole 51. By using this method, and then using the width of the straight rod 32 to be similar to the width of the plug hole 51, the short pin 2 and the long pin 3 can be completely limited. Not only that, by using this limiting position, the position of the short pin 2 and the long pin 3 inserted in the plug hole 51 is fixed. In this way, after the short pin 2 and the long pin 3 are installed, the ends of the short pin 2 and the long pin 3 can be better aligned with the plug-in position of the docking piece, avoiding the pin bending or breaking phenomenon caused by the failure of one pin to align with the plug-in position of the docking piece. This not only affects the transmission process, but also causes the pin to The installation is required, which leads to an increase in cost. The spacer block 4 is fixed to the socket body 5 before the plug-in 1 is connected. The distance between each spacer block 4 is based on the distance between the jacks 51. The connection between the spacer block 4 and the socket body 5 can be fixed or plug-in. The fixed connection method is to insert the spacer block 4 into the installation slot 52 and then fix it by welding. This method may affect the installation process of the short pin 2 and the long pin 3, but the fixed connection can produce a good limiting effect on the short pin 2 and the long pin 3 to prevent the displacement of the short pin 2 and the long pin 3; and the defect of the plug-in connection method is that the short pin 2 and the long pin 3 are fixed by the mutual extrusion between the spacer block 4 and the long pin 3 or the short pin 2, which may cause the short pin 2 and the long pin 3 to become loose, but the advantage is that different models of short pins 2 and long pins 3 can be selected for installation, and the overall replacement is more convenient. After the assembly of the connector is completed, the connector is connected to the docking piece for use.

[0052] In a specific embodiment, Figure 3-Figure 4The socket body 5 includes a socket 51, a mounting groove 52, a connecting block 53, a rectangular block 54, a guide groove 55, a limit groove 56, an extension block 57, a mounting hole 58 and a connecting hole 59. An inner groove is provided on the front surface of the connecting block 53, and a rectangular block 54 is installed in the inner groove. The rectangular blocks 54 are arranged in pairs. The mounting groove 52 is provided at the front end of the connecting block 53, and the mounting groove 52 extends to the rear of the rectangular block 54. A spacer block 4 is inserted in the mounting groove 52. A plurality of sockets 51 are provided on the connecting block In 53, the jack 51 is arranged behind the mounting groove 52, the extension blocks 57 are arranged in pairs and are arranged on the left and right sides of the rectangular block 54, the limit grooves 56 are opened on the inner surface of the extension blocks 57, the guide grooves 55 are arranged in pairs and are opened above the rectangular block 54, the connecting holes 59 are arranged in pairs and are opened on the left and right sides of the connecting block 53, the mounting hole 58 is opened at the rear end of the connecting block 53, the rear end of the jack 51 is connected to the mounting hole 58, and the rear ends of the long pin 3 and the short pin 2 are arranged in the mounting hole 58. The socket 51 is used to insert the pin and the limit block 6, and the mounting groove 52 is used to install the spacer block 4 and place the mounting block 34. After the mounting block 34 is set in the mounting groove 52, the left and right surfaces of the mounting block 34 will be against the surfaces of the spacer block 4 on both sides. In this way, the secondary limit of the long pin 3 and the short pin 2 is realized to prevent displacement. The spacer block 4 is mostly made of a material that is both insulating and does not allow the two magnetic fields to affect each other. Because the connector generally transmits electricity, a magnetic field will be generated when the current passes through the pin. In this way, the spacer block 4 can not only prevent the current from flowing in series, but also prevent the magnetic fields on the two pins from affecting each other, thereby preventing the long pin 3 and the short pin 2 from affecting each other. The operation of the equipment and the transmission of signals are affected. The extension block 57 is used to open the limit groove 56, and the limit groove 56 is used to guide the installation of the docking part. At the same time, the extension block 57 is restricted to the outside of the docking part or inserted into the docking part, which can limit the displacement of the docking part, so that the connection between the connector and the docking part will not be easily loosened. The guide groove 55 is also used to guide the installation of the docking part and limit the left and right movement of the docking part, which can effectively prevent the loosening of the docking part. The rectangular block 54 is used to open the jack 51 and the mounting groove 52. The mounting hole 58 is not connected to the inner groove. The connecting hole 59 is used to install the plug 1.

[0053] In a specific embodiment, Figure 5 The connection hole 59 is a T-shaped structure, in which the insert 1 is inserted. The T-shaped structure of the connection hole 59 is used to restrict the T-block 13, and such a structure can effectively prevent the T-block 13 from slipping out of the connection hole 59. At the same time, the T-shaped structure can also determine the installation depth of the insert 1.

[0054] In a specific embodiment, Figure 6The plug 1 includes a plug 11, an extension piece 12 and a T-block 13. A plurality of extension pieces 12 are arranged on the front and rear surfaces of the upper end of the T-block 13. The plugs 11 are arranged in pairs and installed at the bottom of the T-block 13. The plug 11 is connected to the power source to realize the transmission of electrical signals, and the extension piece 12 contacts the front and rear surfaces of the upper end of the connection hole 59 through its outer end point, so as to limit the T-block 13 and prevent the T-block 13 from moving during use, which affects the power transmission.

[0055] In a specific embodiment, Figure 7 The stopper 6 is a prism structure, and the top surface of the prism structure is against the upper surface of the plug hole 51. By utilizing the protrusion of the prism structure, the top surface of the prism structure contacts the upper surface of the plug hole 51, and at this time, the bottom surface of the plug pin contacts the bottom surface of the plug hole 51, so that the plug pin with the stopper 6 is restricted in the plug hole 51 at this time, and the displacement of the plug pin in the plug hole 51 can be effectively prevented through the friction of the surface contact.

[0056] In a specific embodiment, Figure 8 The limit block 6 is a multi-stage structure, and the top of the multi-stage structure is against the upper surface of the plug hole 51. For the multi-stage structure, multiple small top surfaces are used to contact the top surface of the plug hole 51, so that friction is generated between the surfaces, thereby realizing the limit of the pin and preventing displacement and loosening.

[0057] In a specific embodiment, Fig. 9 The top surface of the limit block 6 is an arc structure, and the upper end of the rear portion of the limit block 6 is a slope structure, and the top of the arc structure is against the upper surface of the plug hole 51. The arc structure adopts a method in which the arc surface is tangent to the upper surface of the plug hole 51, and the pin is limited by friction, and the slope structure is set to produce a certain guiding effect.

[0058] In a specific embodiment, Fig.10 The limit block 6 is an arc-shaped structure, and a hole groove is formed on the bottom surface of the short pin 2, and the top of the arc-shaped structure is against the upper surface of the socket 51. The principle of the arc-shaped structure is similar to that of the arc structure, and friction is generated by the tangency between the upper surface of the socket 51 and the arc surface. The hole groove is designed to be set according to the fixing condition of the pin. The hole groove can be installed with a spring block to push the pin against the socket 51 to achieve the limit, so as to better fix the position and prevent the pin from moving. The hole groove can be placed without anything to reduce the friction between the bottom surface of the pin and the bottom surface of the socket 51. This situation can be adapted to the structure where the pins are frequently replaced, so as to facilitate the replacement of the pins.

[0059] In a specific embodiment, Fig.11, a connection groove is formed on the long pin 3, and the limit block 6 is an elastic pick, which is installed in the connection groove, and the upper end of the elastic pick is against the upper surface of the socket 51. With respect to the design of the elastic pick, through its own elastic properties, when entering the socket 51, the elastic pick will swing slightly downward, and after entering the socket 51, the elastic pick will slightly move upward to reset and abut against the upper surface of the socket 51 by utilizing the properties of the elastic pick, so as to better achieve the limit of the pin.

[0060] In a specific embodiment, Fig.12 The long pin 3 includes a guide head 31, a straight rod 32, a bent rod 33 and a mounting block 34. The mounting block 34 is mounted in the mounting groove 52. The bent rod 33 is arranged at the front end of the mounting block 34. The straight rod 32 is mounted at the rear end of the mounting block 34. The front end of the straight rod 32 is arranged in the socket 51. The guide head 31 is arranged at the rear end of the straight rod 32. The rear end part of the straight rod 32 is arranged in the mounting hole 58. The structure of the long pin 3 is basically similar to that of the short pin 2. The difference lies in the different lengths of the bent rod 33. After the long pin 3 and the short pin 2 are installed in the socket 51, the ends of the bent rod 33 of the long pin 3 and the short pin 2 should be aligned. Moreover, by using the limit block 6, the upper surface of the connecting end of the bent rod 33 of the long pin 3 and the short pin 2 is also flush, so that the end of the bent rod 33 can be easily aligned with the interface of the docking piece, such as Figure 1 As shown, the setting of the guide head 31 enables the straight rod 32 to be better connected to the docking piece. The guide head 31 is used to guide the electrical signal to the straight rod 32, and then transmit the electrical signal to the docking piece connected to the end of the bent rod 33 through the bent rod 33 and the mounting block 34.

[0061] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the present invention. Therefore, these modifications or improvements made without departing from the spirit of the present invention all belong to the scope of protection claimed by the present invention.
