Description

Technical Field

[0001] The utility model relates to the technical field of truss-type manipulators, and more particularly to a pin header connector. Background Art

[0002] Pin headers are generally widely used in the connection of PCB boards and are known as universal connectors. They are generally paired with female headers, wire terminals and other connectors. With the competition in the pin header connector market, some manufacturers now reduce costs by improving electroplating and materials, but this also reduces the product's performance and lifespan.

[0003] Currently, after the pin header and the motherboard are connected, it is not easy to disassemble. Therefore, when a pin in the pin header has a problem, it is difficult to replace the pin header easily. Usually, the pin header and the motherboard are replaced as a whole, which reduces the utilization rate of the pin header and the motherboard, and further increases the consumption of the pin header and the motherboard. Utility Model Content

[0004] The purpose of the present invention is to provide a pin header connector to solve the problem raised in the above-mentioned background technology: currently, after the pin header and the motherboard are connected, it is not easy to disassemble. Therefore, when a problem occurs with a pin in the pin header, it is impossible to easily replace the pin header. Usually, the pin header and the motherboard are replaced as a whole, thereby reducing the utilization rate of the pin header and the motherboard, and then increasing the consumption of the pin header and the motherboard.

[0005] A pin header connector comprises a connecting cavity, wherein the upper end surface of the connecting cavity is provided with a first connecting groove, the inner cavity of the first connecting groove is connected to a pin header assembly, and the inner cavity of the connecting cavity is connected to a blocking assembly.

[0006] Preferably, the blocking assembly includes a pull rod, one end of the pull rod facing the connecting cavity is connected to a U-shaped connecting rod, and the inner sides of both ends of the U-shaped connecting rod are connected to a plurality of blocking mechanisms.

[0007] Preferably, the blocking mechanism includes a first rectangular connecting block, the end of the first rectangular connecting block away from the U-shaped connecting rod is connected to a rectangular blocking block, the inner cavity of the rectangular blocking block is connected to a circular guide rod, the end of the circular guide rod away from the rectangular blocking block is connected to a first return spring, and one end of the first return spring is fixedly connected to the inner cavity of the connecting cavity, and the other end of the first return spring is fixed to one end surface of the rectangular blocking block, the inner cavity of the rectangular blocking block is provided with a circular hole, and the circular hole fits with the circular guide rod.

[0008] Preferably, the end of the rectangular blocking block away from the first return spring is connected to a second rectangular blocking block, the end of the second rectangular blocking block away from the first rectangular connecting block is provided with a rectangular groove, the lower end of the second rectangular blocking block is connected to a second return spring, and the end surface of the second rectangular blocking block facing the first rectangular connecting block is connected to a slider, and the slider is slidably connected to the inner wall of the connecting cavity, and the second blocking block slides up and down.

[0009] By adopting the above technical solution, the U-shaped connecting rod is driven to move toward the other end of the connecting cavity by pushing the pull rod, thereby driving the first rectangular blocking block to move. When the U-shaped connecting rod returns to its original position, the first blocking block is separated from the second rectangular connecting block, which will release the fixing operation of the pin header, so that the problematic pin header can be replaced, thereby reducing the consumption of the mother pin and the pin header.

[0010] Preferably, the pin row assembly includes a pin row, both side surfaces of the pin row are connected with second rectangular connecting blocks, the upper side of each second rectangular connecting block is connected with a rectangular pushing block, and both sides of one end of the pin row are connected with second connecting grooves, the inner cavity of the second connecting groove is connected with a third rectangular connecting block, and the third rectangular connecting block is connected to another pin row, the two pin row are connected by the third rectangular connecting block overlapping the second connecting groove, and the pin row assembly coincides with the first connecting groove.

[0011] By adopting the above technical solution, the two pin headers can be controlled to be connected or separated by overlapping or separating the third rectangular connecting block and the second connecting groove. When the pin header overlaps with the connecting cavity, the pin header assembly can be separated from the female header by pushing the pull rod, thereby making the device detachable.

[0012] Preferably, the rectangular pushing block fits into the rectangular groove.

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] 1) In the present invention, the U-shaped connecting rod is driven to move toward the other end of the connecting cavity by pushing the pull rod, thereby driving the first rectangular blocking block to move. When the U-shaped connecting rod returns to its original position, the first blocking block is separated from the second rectangular connecting block, which releases the fixing operation of the pin header, so that the problematic pin header can be replaced, thereby improving the utilization rate of the pin header and the female header, and reducing the consumption of the pin header and the female header.

[0015] 2) In the present invention, the two pin headers are connected or separated by overlapping or separating the third rectangular connecting block and the second connecting groove, and then the pin header assembly is separated from the female header by pushing the pull rod. This allows the device to be disassembled and reduces the difficulty of maintenance of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] See also Figure 4The blocking mechanism 303 includes a first rectangular connecting block 304, the end of the first rectangular connecting block 304 away from the U-shaped connecting rod 302 is connected to a rectangular blocking block 305, the inner cavity of the rectangular blocking block 305 is connected to a circular guide rod 306, the end of the circular guide rod 306 away from the rectangular blocking block 305 is connected to a first return spring 307, and one end of the first return spring 307 is fixedly connected to the inner cavity of the connecting cavity 1, and the other end of the first return spring 307 is fixed to one end surface of the rectangular blocking block 305, and the inner cavity of the rectangular blocking block 305 is provided with a circular hole, which fits with the circular guide rod 306.

[0025] See also Figure 4 The end of the rectangular blocking block 305 away from the first return spring 307 is connected to the second rectangular blocking block 308, and the end of the second rectangular blocking block 308 away from the first rectangular connecting block 304 is provided with a rectangular groove 309, the lower end of the second rectangular blocking block 308 is connected to the second return spring 310, and the end surface of the second rectangular blocking block 308 facing the first rectangular connecting block 304 is connected to a slider, and the slider is slidably connected to the inner wall of the connecting cavity 1, and the second rectangular blocking block 308 slides up and down.

[0026] See also Figure 5 The needle assembly 4 includes a needle row 401, and the two side surfaces of the needle row 401 are connected to the second rectangular connecting blocks 402, and the upper side of each second rectangular connecting block 402 is connected to a rectangular pushing block 403, and the two sides of one end of the needle row 401 are connected to the second connecting groove 404, and the inner cavity of the second connecting groove 404 is connected to the third rectangular connecting block 405, and the third rectangular connecting block 405 is connected to another needle row 401. The two needle rows 401 are connected by the third rectangular connecting block 405 overlapping the second connecting groove 404, and the needle row assembly 4 coincides with the first connecting groove 2.

[0027] The rectangular push block 403 fits into the rectangular groove 309 .

[0028] Working principle: By aligning the third rectangular connecting block 405 with the second connecting groove 404, the two pin headers 401 are connected, so that the number of pin headers 401 reaches the number required by the user, and then the corresponding connecting cavity 1 is taken out, and the pin header assembly 4 is moved toward the first connecting groove 2. As the pin header assembly 4 moves toward the first connecting groove 2, the rectangular pushing block 403 is aligned with the rectangular groove 309. At this time, as the pin header assembly 4 gradually moves downward, the rectangular pushing block 403 is driven downward, thereby compressing the second return spring 310, and then driving the second rectangular blocking block 308 to move downward until the pin header assembly 4 is completely aligned with the first connecting groove 2.

[0029] When the needle assembly 4 is completely overlapped with the first connecting groove 2, the second rectangular blocking block 308 will be completely separated from the first rectangular blocking block 305, so that the first return spring 307 will perform a reset operation, thereby generating a thrust on the first rectangular blocking block 305, causing the first rectangular blocking block 305 to move along the circular guide rod 306 toward the pull rod 301, and drive the U-shaped connecting rod 302 and the pull rod 301 to move until the first return spring 307 returns to its original position, thereby allowing the first rectangular blocking block 305 to block the second rectangular connecting block 402. When a problem occurs with the needle 401 in the needle assembly 4, by pushing the pull rod 301 inward, the U-shaped connecting rod 302 and the first rectangular connecting block 304 are driven to move toward the direction of the first return spring 307, thereby allowing the first rectangular blocking block 305 to return to its original position. At this time, the problematic needle 401 is removed and then replaced with a new needle 401, and all operations are completed.
