Description

Technical Field

[0001] This utility model relates to the field of communication harness connection technology, and more specifically, to a snap-on communication harness. Background Technology

[0002] Adapters are used in electrical systems such as electronic equipment and electrical facilities to connect cables of different specifications or types to achieve signal transmission or power delivery. One of the most common uses is to connect with a signal expansion dock. However, when a signal expansion dock is connected to a snap-fit ​​communication harness, its snap-fit ​​structure is complex, which increases the cost and is not convenient for adding to communication harnesses without snap-fit.

[0003] For example, the snap-on communication harness adapter assembly and the communication harness including the same disclosed in announcement number CN117276996A include a signal expansion dock. One side of the signal expansion dock is provided with several conductive connection parts that connect to the internal control panel. The side of the signal expansion dock is conductively connected to the communication wire through a snap-on conductive mechanism. The communication wire is connected to the connector conversion assembly. The snap-on conductive mechanism further includes a conductive connection component, which is installed on the side of the signal expansion dock and conductively connected to the control panel inside the signal expansion dock. The conductive connection component is conductively connected to the communication wire.

[0004] As can be seen from the above-disclosed scheme, the female and male connectors of the wire harness connection are fixed by a toothed telescopic assembly and a snap-fit ​​assembly. However, the toothed telescopic assembly and snap-fit ​​assembly consist of a plastic toothed plate, a transmission gear, a protrusion, a guide protrusion, a guide groove, a guide part, a telescopic toothed plate, a magnetic sleeve, a snap-fit ​​rod, and a snap-fit ​​part, etc. Its structure is cumbersome and complex, which increases the production cost. Moreover, the toothed telescopic assembly and snap-fit ​​assembly cannot be installed on existing display plug assemblies, which is not conducive to its widespread use. Utility Model Content

This snap-fit ​​communication cable harness, through the setting of a first clip plate, a second clip plate, and two corresponding guide grooves and slots, can quickly fix the plug-in positions of the male and female plugs. At the same time, the structure is simple, reducing production costs. Furthermore, the mounting holes set in the fixing sleeve and the connection holes set in the clip sleeve allow the fixing sleeve and clip sleeve to modify existing cable harness connectors, facilitating widespread use.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A snap-fit ​​communication cable harness includes a cable harness signal expansion dock. One end of the cable harness signal expansion dock has a female connector, and one end of the female connector has a male connector plugged into it.

At the same time, the structure is simple, reducing production costs. Furthermore, the mounting holes of the fixing sleeve and the connection holes of the clip sleeve allow the fixing sleeve and clip sleeve to modify existing wire harness connectors, facilitating widespread use.

[0008] Furthermore, one end of the male connector is provided with a conductive plug, and a limiting ring is provided on the surface of the male connector. The surface of the limiting ring contacts and presses against one end of the sleeve. A connection hole is provided at the center of the sleeve. The limiting ring can restrict the connection position between the sleeve and the male connector.

[0009] Furthermore, both the first and second latching blocks have arc-shaped surfaces on their surfaces, and each arc-shaped surface has a latching surface at one end. Both the first and second latching blocks are made of wear-resistant metal blocks, which not only make them wear-resistant but also allow them to slide easily within the guide groove.

[0010] Furthermore, the surfaces of the first and second plates are slidably connected to the inner walls of the two guide grooves, respectively. Both the first and second plates are made of elastic metal, and the first and second plates can fix the snap-fit ​​positions of the two snap-fit ​​blocks by elastic force.

[0011] Furthermore, the inner wall of the connecting hole is provided with an internal thread, and the surface of the male connector is provided with an external thread that matches the internal thread of the connecting hole, which facilitates the installation of the ferrule.

[0012] Furthermore, the inner wall of the mounting hole is provided with an internal thread, and the surface of the plug-in female head is provided with an external thread that matches the internal thread of the mounting hole, which facilitates the installation of the fixing sleeve.

[0013] Furthermore, both the fixing sleeve and the clamping sleeve are made of insulating plastic, and their outer contours are polygonal, making it easy to install and remove the fixing sleeve and the clamping sleeve by rotating them with a wrench.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] (1) This solution can quickly fix the insertion position of the male and female connectors by setting the first card plate, the second card plate, and two corresponding guide grooves and card slots. At the same time, the structure is simple and the production cost is reduced.

[0016] (2) This solution uses the mounting holes in the fixed sleeve and the connection holes in the clamp sleeve to allow the fixed sleeve and clamp sleeve to modify the existing wire harness connectors, which is convenient for widespread use. Attached Figure Description

One end of the cable harness signal expansion dock 1 is provided with a female connector 2. The structure and connection method of the female connector 2, male connector 3, and cable harness 33 are all prior art. One end of the female connector 2 is connected to the male connector 3, and one end of the male connector 3 is provided with the cable harness 33. The fixing sleeve 4 and the retaining sleeve 5 are both made of insulating plastic, and their outer contours are polygonal, facilitating the installation and removal of the fixing sleeve 4 and retaining sleeve 5 by rotating with a wrench. The surface of the female connector 2 is threadedly connected to the fixing sleeve 4. One end of the fixing sleeve 4 has a mounting hole 41 in the middle, and the inner wall of the mounting hole 41 is provided with internal threads. The surface is provided with an external thread that matches the internal thread of the mounting hole 41, which facilitates the installation of the fixing sleeve 4. The number of turns of the external thread of the plug-in female head 2 can limit the installation position of the fixing sleeve 4. The inner wall of the mounting hole 41 is provided with radially symmetrical guide grooves 42, and one end of each of the two guide grooves 42 is connected to a retaining groove 43. The surface of the plug-in male head 3 is connected to the retaining sleeve 5 by a thread. The number of turns of the external thread on the surface of the plug-in male head 3 can limit the installation position of the retaining sleeve 5, which facilitates the retaining sleeve 5 and the fixing sleeve 4 to engage after insertion, and prevents the plug-in male head 3 and the plug-in female head 2 from loosening after insertion. One end of the retaining sleeve 5 is provided with a radially symmetrical first retaining plate 52 and a second retaining plate 53. One end of the first retaining plate 52 and the second retaining plate 53 are respectively provided with a first retaining block 54 and a second retaining block 55. The surfaces of the first retaining block 54 and the second retaining block 55 respectively contact and press against the inner walls of the two retaining grooves 43.

[0027] One end of the male connector 3 is provided with a conductive plug 31. The surface of the male connector 3 is provided with a limiting ring 32. The surface of the limiting ring 32 contacts and presses against one end of the sleeve 5. The center of the sleeve 5 is provided with a connecting hole 51. The limiting ring 32 can restrict the connection position between the sleeve 5 and the male connector 3. The surfaces of the first latching block 54 and the second latching block 55 are both provided with an arc-shaped surface 541, and one end of the arc-shaped surface 541 is provided with a latching surface 542. The first latching block 54 and the second latching block 55 are both made of wear-resistant metal blocks. The first latching block 54 and the second latching block 55 are not only wear-resistant, but also easy to slide in the guide groove 42.

[0028] The surfaces of the first clip plate 52 and the second clip plate 53 are slidably connected to the inner walls of the two guide grooves 42, respectively. Both the first clip plate 52 and the second clip plate 53 are made of elastic metal. The first clip plate 52 and the second clip plate 53 can fix the snap-fit ​​position of the two snap-fit ​​blocks by elastic force. The inner wall of the connecting hole 51 is provided with an internal thread, and the surface of the plug-in male head 3 is provided with an external thread that matches the internal thread of the connecting hole 51, which facilitates the installation of the clip 5.

[0029] When connecting this snap-fit ​​communication harness, the male connector 3 is first inserted into the female connector 2, simultaneously causing the first locking plate 52 and the second locking plate 53 to enter the two guide slots 42. When the male connector 3 is fully inserted, the first locking block 54 and the second locking block 55 on the first locking plate 52 and the second locking plate 53 respectively engage with the two slots 43, preventing the male connector 3 from loosening or rotating. When adding this to a communication harness without a snap-fit ​​structure, the fixing sleeve 4 can be threaded onto the surface of the female connector 2. The clamp 5 is attached to the surface of the male connector 3, and then plugged in to complete the fixation through clamping. The first clamping plate 52, the second clamping plate 53, and the two corresponding guide grooves 42 and clamping slots 43 can quickly fix the plugging positions of the male connector 3 and the female connector 2. At the same time, the structure is simple, reducing production costs. Furthermore, the mounting hole 41 of the fixing sleeve 4 and the connection hole 51 of the clamp 5 allow the fixing sleeve 4 and the clamp 5 to modify existing wire harness connectors, making it easy to promote and use.
