Description

Technical Field

[0001] The utility model belongs to the technical field of data transmission devices, and in particular relates to a multi-hardware data collection and connection device. Background Art

[0002] Data transmission is the communication process of transferring data from one device to another. The data transmission system is usually composed of a transmission channel and data circuit termination devices at both ends of the channel. The current data transmission has a variety of structures, some of which use a probe structure, and the receiving end uses a ring structure that matches the probe. The elasticity of the ring is used to achieve direct contact between the probe and the ring after plugging, thereby achieving mutual conduction.

[0003] The Chinese patent with the publication number CN220914662U discloses a data transmission connection structure, including a plug, a socket, a jack, a collar and a pin. The outer side of each collar is coaxially provided with a pushing structure, and the pushing structure includes a contact ring protruding from the end face of the plug and a push piece fixedly connected to the back side of the contact ring, and the end of the push piece fits the outer wall of the collar; when the plug and the socket are connected, the contact ring is completely pushed into the inside of the plug. By coaxially providing a movable groove on the outer side of each jack, and slidingly embedding the pushing structure on the inner side of the movable groove, using the push piece of the pushing structure, when the plug and the socket are plugged, the collar is pushed to its axial position, thereby achieving a conflict with the outer wall of the pin and achieving mutual conduction. When the plug is pulled out, the push piece and the collar are reset under the action of the spring at the end of the pushing structure, thereby reducing the friction between the pin and the collar, which is beneficial to improving the service life of the device and reducing the possibility of contact failure.

[0004] However, in actual use, since part of the push piece needs to slide along the inclined groove and part of it needs to slide along the movable groove, the overlapping length of the push piece with the inclined groove and the movable groove can be changed by changing the position of the contact ring. Therefore, the push piece needs to have good toughness and elastic deformation ability. Otherwise, bending deformation will cause wrinkles on the push piece, thereby affecting the sliding of the push piece in the inclined groove or the movable groove, and multiple back and forth bending will easily cause rigid fatigue of the push piece. In the case of good elastic deformation ability and toughness, the push piece is prone to deformation under force, that is, it is difficult for the push piece to drive the ring to abut on the pin by pressing. That is, the reliability of the above scheme is poor, which is not conducive to actual use. Utility Model Content

[0005] The utility model aims to provide a multi-hardware data collection and connection device to solve the problem of poor reliability of the prior art mentioned above.

[0006] In order to achieve the above object, the utility model provides the following technical solution: a multi-hardware data collection and connection device, comprising

[0007] The socket has a cavity inside, and a pin is installed in the cavity;

[0008] The plug is matched with the insertion cavity, and has a socket, a collar is installed in the socket, and the pin is inserted into the inner side of the collar. A stepped groove is coaxially provided at one end of the socket close to the socket;

[0009] The clamping cylinder is adapted to the stepped groove, fixed in the insertion cavity and coaxially sleeved outside the insertion pin. The inner side of the clamping cylinder is provided with a pressing cavity, which includes a circular transition section and a conical pressing section. The transition section is located at one end of the clamping cylinder close to the socket, the inner diameter of the transition section is larger than the outer diameter of the collar, and the inner diameter of the pressing section away from the collar is smaller than the outer diameter of the collar. The collar passes through the transition section and abuts against the pressing section.

[0010] The principle and effect of this technical solution:

[0011] 1. By setting the transition section and the pressing section of the pressing cylinder, after the pin is inserted into the ring, the ring can be pressed by the conical surface of the pressing section and contact with the pin, thereby playing a connecting function. The method of directly driving the ring to press on the pin through the pressing of the conical surface of the pressing cylinder is more stable and reliable, and only requires the ring to have good elastic deformation ability and toughness.

[0012] 2. The circular transition section and the conical pressing section enable the ferrule to be pressed smoothly against the pin without causing the ferrule to pile up.

[0013] 3. The pins are set to multiple groups such as Figure 1 As shown, the data line on the plug can adopt a multi-core wire structure to meet the needs of a single wire connecting to at least two pins, which can meet the data transmission needs of multiple hardware, so that one connection device can connect multiple hardware through a splitter and meet the needs of multiple hardware to transmit data at the same time.

[0014] The utility model is further configured as follows: a clamping groove is provided on the outer wall of the plug, a clamping strip is fixed on the side wall of the inserting cavity, and the clamping groove is matched with the clamping strip.

[0015] The principle and effect of the technical solution: the provision of the snap-in groove and the snap-in strip can enhance the connection stability between the plug and the socket, while the snap-in strip can enhance the shell strength of the socket.

[0016] The utility model is further configured that: the outer diameter of the plug pin is smaller than the inner diameter of the pressing section away from the socket.

[0017] The principle and effect of this technical solution: by making the outer diameter of the pin smaller than the inner diameter of the socket, the ring can be stored between the pin and the pressing section when pressed by the pressing section, thereby not interfering with the pressing tube being pressed into the stepped groove.

[0018] The utility model is further configured as follows: it also includes a locking mechanism, the locking mechanism includes a mounting tube, an insertion rod, a pressure plate and a spring, a slot is opened on the outer wall of the plug, the mounting tube is fixed on the outer wall of the socket, the insertion rod and the mounting tube are slidably inserted, and the end of the insertion rod passes through the socket and extends into the slot, the pressure plate is fixed on the insertion rod, and the pressure plate is slidably fitted in the mounting tube, the spring is installed in the mounting tube, and is located on the side of the pressure plate away from the socket, and the insertion rod is adapted to the slot.

[0019] The principle and effect of this technical solution: by installing the tube, spring and pressure plate, the insertion rod is driven to approach the slot spontaneously without external force, so that after the plug is installed in the insertion cavity, the insertion rod can be stably inserted in the slot to limit the position of the plug, and the restriction on the plug can be quickly removed by pulling, which makes disassembly and assembly convenient and quick, and has strong stability.

[0020] The utility model is further configured that: a side of the insert rod close to the plug is provided with a guide sliding surface.

[0021] The principle and effect of this technical solution: the setting of the guide sliding surface allows the plug to be inserted into the insertion cavity by pressing the guide sliding surface to drive the plug rod to make way for the plug, so that there is no need to manually pull out the plug rod when the plug is inserted, saving manpower and facilitating installation.

[0022] The utility model is further configured that: the slot and the clamping slot are located on the same axis.

[0023] The principle and effect of this technical solution: by arranging the slot and the card slot on the same axis, when the plug enters the insertion cavity, the insertion rod will not immediately abut against the plug, thereby not restricting the insertion of the plug. When the plug is almost fully inserted, the insertion rod abuts against the side wall of the slot through the guide sliding surface and contracts, thereby serving to remind the operator of the insertion position.

[0024] The utility model is further configured as follows: a pull block is fixed on a side of the plug away from the socket.

[0025] The principle and effect of the technical solution: the setting of the pull block can limit the user's fingers, so that the user can easily pull the plug out of the socket by pressing the pull block with his fingers. BRIEF DESCRIPTION OF THE DRAWINGS
