Description

Technical Field

[0001] The utility model belongs to the technical field of network transmission connectors, and in particular relates to a network transmission module used for quick change. Background Art

[0002] The application of industrial robot quick change involves a lot of network signal transmission. Figure 1 As shown, this type of signal module generally includes a signal pin 1a, a module body 2a, a connector 3a and a single-core signal line 4a. The connector 3a fixes the single-core signal line 4a and the module body 2a, and the single-core signal line 4a and the signal pin 1a are welded together after stripping the wires.

[0003] Manual welding is usually used. Manual welding requires a certain amount of operating space and experience. For example, it is difficult to achieve sufficient winding pitch and length for twisted pairs. Welding defects and manual proficiency may cause the following hazards:

[0004] ① Workers need to peel off the protective layer of a length of cable and unwrap the signal line for soldering. Manual soldering usually requires unwrapping the wires, causing the impedance of the originally standard cable to vary significantly, making the transmission impedance uncontrollable. The impedance is closely related to the winding density, length, and soldering quality, making it difficult to meet high-quality transmission requirements.

[0005] ② In order to facilitate manual operation, a certain amount of space must be left in the module volume, so the final design volume of the module is too large, and it cannot be installed for small kilogram quick change;

[0006] ③It requires experienced producers to produce it.

[0007] For small-load quick-change joints, which are currently used more frequently, the transmission module is smaller in size and the traditional manual welding method is not well applicable. Therefore, it is necessary to design a new type of quick-change network transmission joint module to reduce the volume and reduce the welding difficulty, so that it can be quickly welded by robots, improve welding efficiency, ensure welding accuracy, and thus reduce labor costs. Summary of the Invention

[0008] In view of this, an object of the present invention is to provide a network transmission module for quick replacement with small size and high reliability, so as to overcome the shortcomings of the prior art.

[0009] The purpose of the utility model can be achieved by the following technical solutions: A network transmission module for quick replacement, comprising a first connection module and a second connection module plugged into each other; characterized in that:

The first circuit board is fixedly installed in the first inner cavity. The signal pin assembly and the first network connector extending into the first inner cavity are both soldered to the first circuit board and connected via circuitry arranged on the first circuit board.

[0011] The second connection module includes a second connection module body, a second network connector, a signal contact assembly and a second circuit board. One side of the second connection module body is provided with a plug / slot that matches the first connection module. The second connection module body has a second inner cavity. The signal contact assembly is installed at the plug / slot of the second connection module body and extends into the second inner cavity. The second network connector is installed on the other side of the second connection module body and extends into the second inner cavity. The second circuit board is fixedly installed in the second inner cavity. The signal contact assembly and the second network connector extending into the second inner cavity are both welded to the second circuit board and connected through circuits laid out on the second circuit board.

[0012] Preferably, the signal pin assembly includes a first insulating seat, a spring pin and a pin sleeve. The first insulating seat is installed at the slot / plug of the first connection module body. A plurality of first pin holes are opened on the first insulating seat. The first end of the pin sleeve is installed in the first pin hole. The second end of the pin sleeve passes through the first pin hole and is welded to the first circuit board.

[0016] Compared with the existing technology, the network transmission module used for quick replacement has the following advantages: the utility model uses circuit board wiring instead of single-core signal lines, which is smaller in size and ensures impedance matching consistency, solving the problem of difficulty in ensuring equal length and equal spacing due to the use of single-core signal lines in traditional solutions; the position accuracy of the signal pin assembly / signal contact assembly and the circuit board can be guaranteed through tooling, and auxiliary welding robots can be used for fast welding, ensuring welding accuracy, reducing labor costs and the requirements for operator experience, and having better product consistency and higher reliability.

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] like Figure 2 、 3 As shown, the network transmission module for quick change provided by the present invention is composed of two parts: a first connection module 100 and a second connection module 200. The first connection module 100 and the second connection module 200 are connected and fixed by plugging. The specific structure is as follows:

[0023] The first connection module 100 includes a first connection module body 110, a first network connector 120, a signal pin assembly 130, and a first circuit board 140. A slot 111 is defined on one side of the first connection module body 110. A first inner cavity 112 is defined within the first connection module body 110. The signal pin assembly 130 is mounted in the slot 111 and extends into the first inner cavity 112. The first network connector 120 is mounted on the other side of the first connection module body 110 and extends into the first inner cavity 112. The first circuit board 140 is fixedly mounted within the first inner cavity 112. The signal pin assembly 130 and the portion of the first network connector 120 extending into the first inner cavity 112 are both soldered to the first circuit board 140 and connected via circuitry disposed on the first circuit board 140. In this embodiment, the first connection module body 110 is constructed of an upper and lower base body that are fastened together and secured by bolts. The slot 111 is located on the upper base body and extends through the inner cavity and the exterior. The slot 111, which has a countersunk structure, provides a mounting hole for the signal pin assembly 130.

[0024] The signal pin assembly 130 includes a first insulating seat 131, a spring pin 132, and a pin sleeve 133. The first insulating seat 131 is mounted on the slot 111. A number of regularly arranged first pinholes 134 are defined on the first insulating seat 131. The first end of the pin sleeve 133 is mounted in the first pinholes 134. The second end of the pin sleeve 133 passes through the first pinholes 134 and is soldered to the first circuit board 140. A pin seat 135 is provided on the first end of the pin sleeve 133, into which the spring pin 132 is inserted. The first pinholes 134 are countersunk, and the first end of the pin sleeve 133 has an outward-turned stopper that abuts the bottom of the pinhole. The outer end of the spring pin 132 is retracted into the countersunk hole.

[0025] The first network connector 120 is fixed to the left side of the first connection module body 110 by screwing. The first inner cavity 112 of the first network connector 120 is provided with welding pins, which are fixed to the left side of the first circuit board 140 by welding.

[0026] The second connection module 200 includes a second connection module body 210, a second network connector 220, a signal contact 232 assembly 230, and a second circuit board 240. One side of the second connection module body 210 has a plug 211 that mates with the slot 111 of the first connection module 100. The second connection module body 210 defines a second inner cavity 212. The signal contact 232 assembly 230 is mounted on the plug 211 and extends into the second inner cavity 212. The second network connector 220 is mounted on the other side of the second connection module body 210 and extends into the second inner cavity 212. The second circuit board 240 is fixedly mounted in the second inner cavity 212. The signal contact 232 assembly 230 and the second network connector 220 extending into the second inner cavity 212 are both soldered to the second circuit board 240 and connected via circuitry disposed on the second circuit board 240. Similarly, the second connection module body 210 is also composed of an upper base and a lower base that are fastened together by bolts. The plug 211 is mounted on the upper base and extends through the inner cavity and the exterior. The plug 211 adopts an annular ring structure, the center of the annular ring is hollowed out and sunken to form a mounting hole for mounting the signal contact 232 assembly 230 .

[0027] The signal contact 232 assembly 230 includes a second insulating seat 231 and a contact 232. The second insulating seat 231 is installed at the plug 211 of the second connection module body 210. A plurality of second pinholes 233 are opened on the second insulating seat 231. The first end of the contact 232 is installed in the second pinhole 233. The second end of the contact 232 passes through the second pinhole 233 and is welded to the second circuit board 240. The outer end of the contact 232 protrudes from the outside of the second pinhole 233.

[0028] The second network connector 220 is fixed to the left side of the second connection module body 210 by screwing. The second inner cavity 212 of the second network connector 220 is provided with welding pins, which are fixed to the left side of the second circuit board 240 by welding.

[0029] In order to better achieve rapid docking of the first connection module 100 and the second connection module 200, orientation guide blocks 300 are installed on the first insulating seat 131 and the second insulating seat 231. The orientation guide blocks 300 can guide the operator to quickly align the angle.

[0030] It should be noted that in other embodiments of the present invention, the slot 111 of the first connection module 100 and the plug 211 of the second connection module 200 can be interchanged. In addition, the spring pin 132, the pin sleeve 133 and the contact 232 are all made of metal conductive material and are all needle-shaped structures.

[0031] like Figure 3As shown, during use, following the guidance of the orientation guide block 300, the operator aligns the socket of the first connection module 100 and the plug 211 of the second connection module 200. Then, they move closer together until the plug 211 is inserted into the socket. At this point, the spring pins 132 in the socket come into contact with the contacts 232 in the plug 211, connecting the circuit boards in the two connection modules and forming a pathway for signal transmission. By using circuit boards for circuit layout, traditional single-core signal cables are eliminated, reducing the module size and effectively ensuring impedance consistency of the circuits.

[0032] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
