Detailed Implementation

[0029] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0030] The applicant believes that the existing printer connection harness is usually connected to the printer by a plug-in method. This connection method is prone to loosening when frequently plugged in or unplugged or under vibration, which can cause printing to be stuck or interrupted, and has certain shortcomings.

[0031] Therefore, the applicant proposes a printer connection harness, such as Figures 1-5 As shown, it includes a wire section 1, an inner connector section 2, and an outer connector mechanism.

[0032] The inner connector 2 is connected to the wire part 1, and the outer connector mechanism is installed on the inner connector 2. The inner connector 2 includes a connector housing 201 installed at the end of the wire part 1 and a plug 202 connected to the end of the connector housing 201 for plugging into the printer. The outer connector mechanism includes a fixing part 3 connected to the connector housing 201, an outer connector 5 rotatably disposed on the fixing part 3, and a protective part 4 connected to the side of the fixing part 3 away from the plug 202.

[0033] In this application, the fixing part 3 is fixed on the connector housing 201 and is used to connect the protective part 4 and the outer connector part 5. The outer connector part 5 is movably disposed on the fixing part 3 and can slide and rotate, etc., for threaded connection and magnetic connection with the printer. It can cooperate with the plug connector 202 to plug into the printer, improve the stability of the connection between the wire harness connector and the printer, thereby reducing the occurrence of loosening of the connection between the wire harness connector and the printer under conditions such as frequent plugging and unplugging or vibration, and protecting the normal use of the printer.

[0034] In addition, when the printer wiring harness is in use, the base of the wiring harness, especially the part near the wiring harness connector, is prone to repeated bending, which may cause internal wire breakage. Therefore, a protective part 4 is provided. The protective part 4 can be made of rigid PVC material, which can protect the base of the wiring harness, thereby improving its bending resistance and protecting its normal use.

[0035] Specifically, such as Figures 1-4 As shown, the fixing part 3 includes a fixing bracket 301, a first connecting ear 302, a first fixing bolt 303, a limiting baffle 304, a third fixing hole 305, and a third fixing nail 306.

[0036] The set includes a pair of fixed brackets 301, which are correspondingly snapped onto the connector housing 201. Two sets of first connecting ears 302 are provided, which are respectively connected to the pair of fixed brackets 301. A first fixing bolt 303 is installed on the first connecting ear 302 to fix the pair of fixed brackets 301. A limiting baffle 304 is connected to the fixed brackets 301. A third fixing hole 305 is opened on the limiting baffle 304 and the limiting ring 502. A third fixing nail 306 is adapted to the third fixing hole 305 to fix the outer connector part 5 and the fixing part 3.

[0037] In this application, a pair of fixed brackets 301 are provided with a slot and a matching block on their adjacent sides, so that the pair of fixed brackets 301 can be snapped onto the connector housing 201. An elastic pad is provided between the pair of fixed brackets 301. The pair of fixed brackets 301 can be further fixed onto the connector housing 201 by using the first fixing bolt 303 to fix them in the first connecting ear 302. Each fixed bracket 301 is connected to a limit baffle 304 to limit the movement distance of the outer connector part 5. The third fixing hole 305 and the third fixing nail 306 can fix the fixing part 3 and the outer connector part 5, thereby fixing the outer connector part 5 onto the inner connector part 2.

[0038] like Figures 1-3 As shown, the external connector 5 includes a threaded connector 501, a limiting ring 502, a positioning slot 503, a positioning block 504, a first fixing hole 505, a first fixing pin 506, and a magnetic ring 507.

[0039] The threaded connector 501 is slidably mounted on the fixed bracket 301 for threaded connection with the printer. The limiting ring 502 is installed on the side of the threaded connector 501 near the lead wire 1 for limiting the movement distance of the threaded connector 501 in conjunction with the limiting baffle 304. The positioning slot 503 is opened on the threaded connector 501. The positioning block 504 is connected to the limiting ring 502 and is adapted to the positioning slot 503 for engaging the threaded connector 501 and the limiting ring 502. The first fixing hole 505 is correspondingly opened on the limiting ring 502 and the threaded connector 501. The first fixing pin 506 is adapted to the first fixing hole 505. The magnetic ring 507 is disposed on the threaded connector 501.

[0040] In this application, the threaded connector 501 has an external thread at a predetermined distance at its end. The inner wall of the threaded connector 501 is adapted to the outer wall of the limiting baffle 304, allowing the threaded connector 501 to move in contact with the limiting baffle 304, including sliding and rotating. The limiting ring 502 is provided to cooperate with the limiting baffle 304 to limit the movement range of the threaded connector 501, restricting the threaded connector 501 to a certain extent on the fixing part 3. The positioning slot 503 and the positioning block 504 are provided to engage the limiting ring 502 and the threaded connector 501, and to position the first fixing hole 505 and the first fixing pin 506 for installation. The first fixing hole 505 and the first fixing pin 506 are provided to further lock and fix the limiting ring 502 and the threaded connector 501. The magnetic ring 507 is provided so that the outer connector part 5 can be magnetically connected to the printer.

[0041] During installation, first slide the limiting ring 502 from the end of the plug 202 to the position of the wire part 1. Then, snap a pair of fixing brackets 301 onto the connector housing 201. Next, lock the first fixing bolt 303 onto the first connecting ear 302 and further lock the pair of fixing brackets 301. Then, slide the threaded connector 501 from the end of the plug 202 a predetermined distance so that the threaded connector 501 slides into contact with the limiting baffle 304. Then, use the positioning slot 503 and the positioning block 504 to snap the limiting ring 502 and the threaded connector 501 together. Finally, screw the first fixing pin 506 into the first fixing hole 505 to further lock the limiting ring 502 and the threaded connector 501.

[0042] Meanwhile, the third fixing pin 306 can be screwed into the corresponding third fixing hole 305 on the limiting ring 502 and the limiting baffle 304 to fix the fixing part 3 and the external connector part 5, thereby improving the stability of the connection between the present application and the printer. The setting of the external connector part 5 and the fixing part 3 can not only reduce the possibility of loose connection between the connector 202 and the printer, but also provide relative sealing protection for the connection between the connector 202 and the printer, thus protecting the normal use of the printer.

[0043] In addition, such as Figure 5 As shown, according to the corresponding components of this application, a threaded interface 8 and a magnetic contact block 9 need to be set on the printer. The plug interface 7 is an interface on the existing printer that is compatible with the plug connector 202. When in use, the plug connector 202 is inserted into the plug interface 7 until the end of the connector housing 201 abuts against the printer housing. Then, the threaded connector 501 is moved to slide a predetermined distance on the limiting baffle 304 so that the threaded connector 501 is close to the printer housing. Then, the threaded connector 501 is rotated so that the threaded connector 501 is screwed into the threaded interface 8 until the magnetic ring 507 and the magnetic contact block 9 are attracted together.

[0044] It should be noted that the threaded connector 501 and the threaded interface 8 are the main auxiliary connecting components, while the magnetic ring 507 and the magnetic block 9 are secondary auxiliary connecting components. In actual use, the magnetic ring 507 and the magnetic block 9 can be selected for installation.

[0045] In addition, such as Figures 1-4 As shown, the external connector mechanism also includes a protective part 4, which includes a connecting plate 401, a protective shell 402, a second fixing hole 405, a second fixing nail 406, a second connecting ear 403, and a second fixing bolt 404.

[0046] The connecting plate 401 is located on the side of the fixing bracket 301 away from the plug 202. The protective shell 402 is connected to the connecting plate 401 and located outside the wire part 1 to protect the wire part 1. The second fixing hole 405 is correspondingly opened on the connecting plate 401 and the fixing bracket 301. The second fixing nail 406 is adapted to the second fixing hole 405 to lock and fix the connecting plate 401 and the fixing bracket 301. There are two second connecting ears 403, which are correspondingly connected to a pair of protective shells 402. The second fixing bolt 404 is installed on the second connecting ears 403 to lock and fix the two second connecting ears 403.

[0047] In this application, the protective part 4 is used to protect the part of the wire harness of the conductor part 1 near the connector housing 201. The connecting plate 401 is connected to the fixing bracket 301 in conjunction with the second fixing hole 405 and the second fixing nail 406. The protective shell 402 is set on the outside of the conductor part 1. The sides of the pair of protective shells 402 that are close to each other are also provided with corresponding locking blocks and locking slots that are adapted to the locking blocks for the pair of protective shells 402 to lock together. Then, the second fixing bolt 404 is fixed in the second connecting ear 403, which can further lock and fix the pair of protective shells 402, thereby protecting the root of the conductor part 1 near the connector housing 201 at a predetermined distance, improving its bending resistance, and protecting its normal use, etc.

[0048] In addition, elastic pads are provided between a pair of protective shells 402 and between a pair of protective shells 402 and the wire part 1, which can be used for elastic compression.

[0049] In addition, such as Figure 1 As shown, this application also includes a threaded sleeve 6.

[0050] The threaded connector 501 has a threaded sleeve 6 at its end for protecting the inner connector part 2.

[0051] In this application, when the wire harness is not in use, the threaded sleeve 6 can be screwed onto the end of the threaded connector 501, and the third fixing pin 306 can be screwed into the corresponding third fixing hole 305 on the limiting ring 502 and the limiting baffle 304 to fix the fixing part 3 to the outer connector part 5. This can protect the connector housing 201 and the plug connector 202 and other components, reduce the possibility of collision damage to the plug connector 202, and protect the normal use of the plug connector 202 and other components.

[0052] As described above, although the present invention has been shown and described with reference to specific preferred embodiments, it should not be construed as limiting the present invention itself. Various changes in form and detail may be made to the present invention without departing from the spirit and scope of the appended claims.
