Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connector that prevents reverse mutual insertion from short circuiting. Background Art

[0002] At present, in the field of connectors, there is a connector that prevents reverse interplugging, which mainly prevents the plug and the socket from being reversely plugged in when they are normally connected by setting a corresponding interlocking mechanism on the connector, thereby avoiding the occurrence of problems such as short circuit or open circuit. However, the existing connectors that prevent reverse interplugging still have some problems. For example, when the plug-in direction of the plug and the socket is wrong, although the connector itself can prevent reverse interplugging, the plug-in force is too large or too small, which may cause the interlocking mechanism of the connector to be damaged or unable to work normally. Therefore, in order to solve the above problems, it is necessary to design a new type of connector that prevents reverse interplugging and short circuit. To this end, the inventor proposes a connector that prevents reverse interplugging and short circuit to solve the above-mentioned technical problem of preventing the reverse interplugging of the connector, which causes the interlocking mechanism of the connector to be damaged or unable to work normally.

[0005] Since both ends of the pin header are provided with connecting codes and both ends of the female header are provided with mounting codes used in pair with the connecting codes, this design ensures that electrical connection can be established only when inserted in the correct direction, thereby avoiding the risk of short circuit. The plug-in block is in the shape of a body and has an internal hollow opening. This design enables the plug-in block to cooperate with the limit slot more stably, further improving the reliability of the connector, and the middle of the connecting code and the mounting code are respectively installed with a connecting sleeve and a mounting screw sleeve, which makes the installation process simpler and faster; in addition, the surfaces of the connecting code and the mounting code are provided with connecting holes for connecting external bolts, which enables the connector to be connected to other external devices or components, thereby improving its application flexibility and ensuring the stability and reliability of signal transmission.

[0006] Furthermore, the connection assembly includes a probe and a pin, the probe is installed at one end of the female connector, and a plurality of step grooves are provided at one end of the female connector away from the probe, the step grooves are linearly arranged on the surface of the female connector, the distance between two adjacent step grooves is equidistant, the number of step grooves is consistent with that of the probe, and they are coaxially arranged structures, and one end of the probe extends to the inside of the step groove;

[0007] The extension of the probe into the inside of the stepped groove can increase the stability of the connection between the whole, reduce vibration or movement caused by external factors, thereby improving the stability of the overall structure, and the extended part of the probe entering the stepped groove can provide additional connection strength, which helps to prevent the probe from loosening or falling off the mother row, thereby improving the reliability of the whole piece; in addition, the extension of the probe into the stepped groove can simplify the assembly process, making the connection between the probe and the mother row more convenient and quick, while reducing possible errors or problems during the assembly process. Since the stepped groove and the probe are coaxially arranged, this can ensure that the connection between the extended part of the probe and the inside of the stepped groove has a higher coaxiality, thereby improving the coaxiality and symmetry of the entire connection assembly, thereby reducing the interference of external factors on the connection, enhancing the electrical performance of the connection, and improving the quality and stability of signal transmission.

[0008] Furthermore, the pin is installed at one end of the pin header, the pin penetrates the surface of both ends of the pin header, one end of the pin is a pin seat, the pins are linearly arranged on the surface of the pin header, the distance between two adjacent pins is equidistantly set, the number of pins is consistent with the number of stepped grooves, and they are coaxially arranged structures;

[0009] The pin is installed at one end of the pin header, which enables the pin to be stably fixed on the pin header. The pin runs through the surfaces of both ends of the pin header, ensuring the strength and stability of the pin, making it difficult to bend or move when subjected to large force or torque. One end of the pin is a pin holder, which provides stable support for the pin and facilitates the installation and fixation of the pin; the pins are linearly arranged on the surface of the pin header. This arrangement allows the pins to be arranged in an orderly manner, facilitating subsequent connection and assembly. The distance between two adjacent pins is set equidistantly, which ensures that each pin can bear the force evenly and avoids damage caused by uneven force. The setting of the same number of pins and step grooves allows the pins and step grooves to correspond one to one, simplifying the assembly process, improving work efficiency, and ensuring that the pins will not be offset or twisted when transmitting force or torque, thereby ensuring their stability and reliability.

[0010] Furthermore, a plurality of support blocks are provided inside the hub, and a spacer block is connected between two adjacent support blocks. The step groove is located on the surface of the support block, and the support block is used to support the probe; the support block is used to support the probe and can provide a more stable and reliable supporting force to prevent the probe from bending or breaking when inserting or removing it. In addition, the design of the support block can also effectively reduce the friction between the probe and the hub, thereby improving the service life and reliability of the probe.

[0011] Furthermore, the pin header is provided with a plurality of fixed blocks for limiting the position of the pins, and a limiting block is connected between two adjacent fixed blocks. The pins are located on the surface of the fixed blocks, and the fixed blocks are used to support the pins and the pin holders;

[0012] Since the pin is supported by the fixed block, its shaking inside the pin header can be reduced and the stability of the entire pin header is improved. The fixed block and the limit block together constitute a bracket inside the pin header, making the pin header more sturdy and durable, able to withstand greater external pressure and impact, and play a role in enhancing mechanical strength. Since the pin is limited by the fixed block, the accurate positioning of the pin inside the pin header can be ensured, thereby ensuring the accuracy of the entire pin header. If the pin is damaged or needs to be replaced, it can be operated by removing the fixed block, which is convenient and quick, and easy to maintain and repair.

[0013] Furthermore, a cover plate is connected to the surface of the female row, and the cover plate is used to support the support block and the spacer block. The cover plate is flush with the surface of the female row, and one end of the female row is connected to a plurality of blocking blocks, and the probe is located between two adjacent blocking blocks;

One end of the mother header is connected to several block blocks, and the probe is located between two adjacent block blocks. This design allows the probe to accurately detect the product while maintaining stability, thereby ensuring the accuracy and reliability of the detection. At the same time, the design of the block block can effectively prevent the movement and misalignment of the probe, further improving the accuracy and efficiency of the detection.

The top plate is flush with the surface of the pin header. This design makes installation and maintenance more convenient. The top plate can be used as a platform to make the installation and maintenance process easier and reduce the difficulty of operation. The needle holder is located between two adjacent baffles. This design enables the needle holder to adapt to more installation environments. At the same time, due to the presence of the baffle, the position and angle of the needle holder can be adjusted as needed, which improves the compatibility and scalability of the system.

[0017] Furthermore, the middle parts of the connecting sleeve and the mounting screw sleeve are connected with mounting bolts, and the mounting bolts play a floating and guiding role; the floating effect of the mounting bolts can absorb the assembly error between the connecting sleeve and the mounting screw sleeve, making the connection between the two more flexible, reducing the stress concentration problem caused by the assembly error, improving the stability of the overall structure, and reducing the floating effect; in addition, the guiding effect of the mounting bolts can ensure the correct relative position between the connecting sleeve and the mounting screw sleeve, avoid misalignment or tilt during the assembly process, improve the assembly accuracy and efficiency, and play a guiding role.

[0018] Compared with the prior art, the beneficial effects of the utility model are as follows: the connection codes at both ends of the pin row and the installation codes at both ends of the female row are matched with each other.
