Description

Technical Field

[0001] The present invention relates to the technical field of electrical connections, and in particular to a data transmission mechanism. Background Art

[0002] Data transmission is the communication process of data being transferred from one device to another. A data transmission system usually consists of a transmission channel and data circuit-terminating equipment at both ends of the channel. Sometimes, it also includes multiplexing equipment at both ends of the channel. The transmission channel can be divided into wired channels and wireless channels according to the transmission medium. Wired channels include open wires, symmetrical cables, coaxial cables, and optical cables; wireless channels include microwave, satellite, scatter, ultra-short wave, and short wave channels; among them, wired channels are more widely used.

[0003] Most of the existing wired channels use plugs to connect to devices. Currently, for the connection between plugs and devices on the market, most of them are that there are small red dots on the devices to mark the connection positions of the plugs, and the operator can connect the plug to the device after following the indicated positions marked.

[0004] Although the plug can find the position of the jack on the device through the set small red dots, the connection between the plug and the jack still needs to be aligned in direction, and the insertion is extremely inconvenient; moreover, the connection between the plug and the device is only the insertion of the plug terminals of the plug into the jacks of the device, and the connection structure is extremely unstable, easily causing the plug to separate from the device, and there are certain potential hazards.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0035] A data transmission mechanism provided by the present invention, such as Figure 1 and Figure 2As shown in the figure, the plug terminals of the plug 100 of the data transmission mechanism are connected to the insertion holes of the interface device. There are mounting holes on the interface device, and the locking seat 200 is installed in the mounting holes of the interface device. There is a mounting groove 201 on the locking seat 200, and the locking latch 300 is installed in the mounting groove 201. The axis of the torsion spring 303 is arranged parallel to the plate surface of the clamping member 301, and one end of the torsion spring 303 abuts against the clamping member 301, and the other end of the torsion spring 303 abuts against the inner wall of the mounting groove 201 of the locking seat 200; the plug terminals of the plug 100 pass through the mounting groove 201 and are inserted into the insertion holes, and one end of the plug 100 provided with the plug terminals abuts and is fixed to the clamping member 301 under the torsion force of the torsion spring 303; the plug terminals of the plug 100 pass through the mounting groove 201 and are inserted into the insertion holes to realize data transmission; one end of the plug 100 provided with the plug terminals abuts and is fixed to the clamping member 301 under the torsion force of the torsion spring 303. Through the action of the torsion spring 303, the clamping of the clamping member 301 and the plug 100 is realized, avoiding the instability of the connection structure where the plug terminals are directly connected to the insertion holes.

[0036] It should be noted that the torsion spring 303 can be set as a 135-degree torsion spring 303 or a torsion spring 303 with other degrees to realize the control of the clamping member 301.

[0037] There is a first clamping protrusion 302 on the bottom surface of the clamping member 301, and a second clamping protrusion 101 on the upper surface of the plug 100. When the plug 100 is inserted, it gradually moves along the clamping member 301 towards the inside of the mounting groove 201, and the second clamping protrusion 101 contacts the clamping member 301. When the second clamping protrusion 101 contacts the front end of the clamping member 301, the clamping member 301 first rotates counterclockwise under the action of the second clamping protrusion 101, so that the front end of the clamping member 301 is separated from the second clamping protrusion 101. When the first clamping protrusion 302 of the plug 100 exceeds the second clamping protrusion 101, the locking latch 300 returns to its original state under the action of the torsion spring 303, and the plug 100 is connected to the mounting groove 201. At this time, the first clamping protrusion 302 is abutted by the second clamping protrusion 101, and the plug 100 cannot be pulled out, realizing the fixation of the plug 100 in the mounting groove 201. When the plug 100 needs to be pulled out, press the inclined part on the left side of the clamping member 301, and the right side of the clamping member 301 is lifted, so that the first clamping protrusion 302 is separated from the second clamping protrusion 101, and the plug 100 is pulled out. After being pulled out, the clamping member 301 returns to the horizontal state under the action of the torsion spring 303; through the contact and separation of the first clamping protrusion 302 and the second clamping protrusion 101, the structure is simple, realizing the stable connection between the plug 100 and the interface device.

[0038] Such as Figure 4 、 Figure 5 and Figure 6As shown, the connecting hole 203 is horizontally arranged along the insertion direction of the plug 100, and the connecting groove 202 is arranged on the upper end face of the locking seat 200 to realize the installation and fixation of the locking 300.

[0039] Specifically, as Figure 4 and Figure 5 shown, the connecting groove 202 is vertically arranged, the connecting hole 203 is horizontally arranged, and the connecting groove 202 and the connecting hole 203 are arranged perpendicular to each other, which is convenient for the arrangement of the installation groove 201. At the same time, it is convenient for the two ends of the torsion spring 303 to abut.

[0040] As Figure 4 and Figure 5 shown, the axis of the torsion spring 303 is perpendicular to the axis of the insertion direction of the plug 100, which is convenient for abutting against the plug 100.

[0041] Specifically, as Figure 3 and Figure 6 shown, the first clamping protrusion 302 is provided as a downward protrusion at the right end of the bottom surface of the clamping member 301, and the second clamping protrusion 101 is provided at the right side portion of the upper surface of the plug 100. When the plug 100 needs to be inserted into the connecting hole 203, as the plug 100 is inserted, when the second clamping protrusion 101 of the plug 100 contacts the clamping member 301, the clamping member 301 rotates counterclockwise along the axis perpendicular to the insertion direction of the plug 100 under the action of the second clamping protrusion 101, so that the right end of the clamping member 301 moves away from the plug 100; when the right end of the second clamping protrusion 101 of the plug 100 contacts the left end of the first clamping protrusion 302 of the clamping member 301, the first clamping protrusion 302 is pushed up under the action of the second clamping protrusion 101. As the plug 100 continues to enter, the second clamping protrusion 101 of the plug 100 exceeds the right end of the clamping member 301. When the left end of the second clamping protrusion 101 exceeds the right end of the first clamping protrusion 302 of the clamping member 301, the clamping member 301 returns to its original state under the action of the elastic element, and the second clamping protrusion 101 is clamped by the first clamping protrusion 302, and the plug 100 cannot be pulled out, realizing the stable connection of the plug 100 in the installation hole; when the plug 100 needs to be pulled out, press the left side of the clamping member 301, the right side of the clamping member 301 is lifted, so that the first clamping protrusion 302 is separated from the second clamping protrusion 101, and the plug 100 is pulled out. After being pulled out, the clamping member 301 returns to the horizontal state under the action of the elastic element; the left end of the plug 100 is connected to the data acquisition device, and the right end of the plug 100 is provided with a plug-in piece, and the plug-in piece is connected to the receiving end on the device to realize the transmission of data.

[0042] As Figure 4 、 Figure 5 and Figure 6As shown in the figure, the clamping member 301 is arranged in the connection hole 203 and connected to the upper surface of the connection hole 203. The lower surface of the connection seat 304 is arranged in contact with the upper surface of the clamping member 301. The number of connection seats 304 is two. The two connection seats 304 and the locking seat 200 are connected by a rotating shaft 305. The connection seat 304 is rotatably connected to the locking seat 200 through the rotating shaft 305. The torsion spring 303 is sleeved on the rotating shaft 305 and is located between the two connection seats 304. One end of the torsion spring 303 abuts against the inner wall of the connection groove 202, and the other end of the torsion spring 303 abuts against the upper surface of the clamping member 301. When the plug 100 needs to be inserted into the connection hole 203, the second clamping protrusion 101 on the upper surface of the plug 100 contacts the lower surface of the clamping member 301. Under the action of the second clamping protrusion 101, the clamping member 301 first rotates counterclockwise around the rotating shaft 305. When the second clamping protrusion 101 moves beyond the position of the rotating shaft 305, the clamping member 301 rotates counterclockwise around the rotating shaft 305, and the right end of the clamping member 301 moves upward, so that the first clamping protrusion 302 is lifted. At this time, the torsion spring 303 is tightened, and the second clamping protrusion 101 can pass through the right end of the clamping member 301. When the second clamping protrusion 101 exceeds the right end of the clamping member 301, the acting force of the second clamping protrusion 101 on the clamping member 301 disappears. Under the action of the torsion spring 303, the clamping member 301 returns to its original position, and the front end of the first clamping protrusion 302 is closely arranged with the rear end of the second clamping protrusion 101, realizing the stable connection of the plug 100. When it is necessary to disassemble the plug 100 and the device, press the left end of the clamping member 301, so that the clamping member 301 rotates counterclockwise, and the right end of the clamping member 301 is lifted, so that the locking effect of the first clamping protrusion 302 on the second clamping protrusion 101 disappears. At this time, the second clamping protrusion 101 can be disengaged from the connection hole 203, realizing the disconnection of the plug 100 and the interface device. The connection structure of the first clamping protrusion 302 and the second clamping protrusion 101 makes the connection structure of the plug 100 and the interface device stable, convenient to disassemble, simple in structure, convenient to insert, and improves the convenience of plugging and unplugging.

[0043] As Figure 3 shown, the second clamping protrusion 101 of the plug 100 is a stepped structure. When the second clamping protrusion 101 contacts the first clamping protrusion 302, it contacts layer by layer from bottom to top. The structure is inclined from left to right towards the end away from the plug terminal, which can reduce the contact area between the second clamping protrusion 101 and the first clamping protrusion 302, making it easier for the second clamping protrusion 101 to pass through the bottom surface of the first clamping protrusion 302 and then pass through the first clamping protrusion 302.

[0044] As Figure 6As shown, the left side of the first clamping projection 302 is arc-shaped, which can avoid abrasion of the second clamping projection 101 of the plug 100, and is more convenient for the contact and passing through of the second clamping projection 101 and the first clamping projection 302.

[0045] As Figure 1 and Figure 2 As shown, the clamping seat 205 is installed in the connection hole 203. An installation through hole 204 is provided on the clamping seat 205, and the clamping member 301 is arranged in the installation through hole 204. The clamping seat 205 can achieve stable connection with the plug 100 inserted subsequently, and wrap the plug 100 inside the clamping seat 205, avoiding the problem that the plug 100 is exposed to the outside and poses a safety hazard.

[0046] As Figure 2 As shown, an electrical connection seat 501 is provided at the left end of the connecting plate 500. The insertion hole is provided on the electrical connection seat 501. The connecting plate 500 is connected to the right side of the locking seat 200. The plug terminal of the plug 100 is connected to the electrical connection seat 501 to achieve the transmission of device data.

[0047] As Figure 2 As shown, the connecting bracket 600 is connected between the locking seat 200 and the connecting plate 500. A through hole 601 adapted to the electrical connection seat 501 is provided on the connecting bracket 600, and the electrical connection seat 501 passes through the through hole 601, which is convenient for connection with the plug 100; the connecting plate 500, the connecting bracket 600 and the locking seat 200 are connected by screws.

[0048] As Figure 3 As shown, an anti-slip portion is provided on the upper surface of the plug 100 away from the plug terminal, which is convenient for pulling out the plug 100. A marking portion is also provided on the upper surface of the plug 100, which is convenient for the user to insert the plug 100.

[0049] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
