CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims the benefit of the filing date under 35 U.S.C. § 119 (a)-(d) of Chinese Patent Application No. 202420027159.1, filed on Jan. 5, 2024.
FIELD OF THE INVENTION
The present invention relates to a cable fixing device, a connector housing assembly comprising the cable fixing device, and a connector comprising the connector housing assembly.
BACKGROUND OF THE INVENTION
Cables of a connector are commonly tied and fixed with a zip tie or secured with a seal and a specialized cable clamp. However, the zip tie is usually only used to tie and secure single row cables, and is not suitable for securing multiple rows and columns of cables. Using a seal and a specialized cable clamp for multiple cables, however, increases costs.
SUMMARY OF THE INVENTION
A cable fixing device includes a fixing component having a plurality of cable holes and a slot transversely running through the plurality of cable holes, and a locking component having a plurality of slot holes corresponding to the plurality of cable holes. The locking component is inserted into the slot of the fixing component and is movable between a pre-lock position and a final-lock position. One of the slot holes aligns with one of the cable holes and a cable is passable through the one of the cable holes and the one of the slot holes in the pre-lock position. The one of the slot holes is offset from the one of the cable holes in the final-lock position and an inner wall surface of the one of the slot holes presses against the cable passing through the one of the cable holes to lock the cable.

Elastic buckles 12a with locking protrusions 12b, as shown in FIGS. 5-7 and 10-11, are respectively formed on the left and right sides of the locking component 12. A first protrusion 11a, a second protrusion 11b, and a snap slot 11c located between the first protrusion 11a and second protrusions 11b are formed on the left and right sides of the slot 111 of the fixing component 11, respectively.
As shown in FIGS. 7-9, in the illustrated embodiment, when the locking component 12 is in the pre-lock position, the locking protrusion 12b on the elastic buckle 12a engages with the snap slot 11c to hold the locking component 12 in the pre-lock position.
As shown in FIGS. 10-12, in the illustrated embodiment, when the locking component 12 is in the final-lock position, the locking protrusion 12b on the elastic buckle 12a engages with the second protrusion 11b to hold the locking component 12 in the final-lock position.
As shown in FIGS. 1, 5-7, and 10-11, in the illustrated embodiment, the slot hole 102 on the locking component 12 is elliptical in shape and a size of the slot hole 102 in the first direction Z is larger than its size in the second direction X. A diameter of the cable hole 101 is equal to or slightly larger than a diameter of the cable 2, and the size of the slot hole 102 in the second direction X is equal to or slightly larger than the diameter of the cable 2.

As shown in FIGS. 1 and 5, in the illustrated embodiment, the two inner sides of the lower slot 112 of the fixing component 11 are perpendicular to the second direction X and are adapted to rest on the outer sides of a pair of lower guide ribs 32 of the housing 3, to guide the fixing component 11 to be inserted into the installation port 30 of the housing 3 along the axial direction Y of the cable hole 101.
As shown in FIG. 5, in the illustrated embodiment, a pair of guide slots 114 are formed on the upper side of the fixing component 11, and the upper slot 113 is located between the pair of guide slots 114. The pair of guide slots 114 are used to cooperate with a pair of upper guide ribs 34 on the housing 3, as shown in FIGS. 1 and 9, to guide the fixing component 11 to be inserted into the installation port 30 of the housing 3 along the axial direction Y of the cable hole 101.
As shown in FIGS. 1-12, in the illustrated embodiment, the fixing component 11 is in the shape of a plate with a predetermined thickness, the slot 111 extends radially along the cable hole 101, and the locking component 12 cooperates with the slot 111.
As shown in FIGS. 1-12, in the illustrated embodiment, multiple cable holes 101 are arranged in multiple rows and columns.
The connector housing assembly is now described in more detail in reference to FIGS. 1-12. The connector housing assembly comprises the housing 3 and the cable fixing device 1. The housing 3, as shown in FIGS. 1-3, 9, and 12, has the installation port 30. The cable fixing device 1 is installed into the installation port 30 of the housing 3.
As shown in FIGS. 1 and 3, in the illustrated embodiment, locking slots 31 are formed on the left and right inner wall surfaces of the installation port 30 of the housing 3, respectively. The locking slots 31 are used to engage with the elastic locking buckles 110 on the fixing component 11 of the cable fixing device 1 to lock the cable fixing device 1 in the installation port 30 of the housing 3.
As shown in FIG. 1, in the illustrated embodiment, the locking slot 31 has a locking surface 31a perpendicular to the axial direction Y of the cable hole 101, and the protruding portions 110a on the elastic locking buckle 110 is pressed against the locking surface 31a to prevent the cable fixing device 1 from being pulled out from the installation port 30 of the housing 3.
As shown in FIGS. 1 and 9, in the illustrated embodiment, a pair of lower guide ribs 32 are formed on the inner wall surface of the lower side of the installation port 30 of the housing 3. The outer side of the pair of lower guide ribs 32 is adapted to be pressed against the inner side of the lower slot 112 of the fixing component 11 to guide the fixing component 11 to be inserted into the installation port 30 of the housing 3 along the axial direction Y of the cable hole 101.
As shown in FIG. 1, in the illustrated embodiment, a pair of positioning protrusions 33 are also formed on the inner wall surface of the lower side of the installation port 30 of the housing 3, and the pair of positioning protrusions 33 are respectively connected to the pair of lower guide ribs 32. The fixing component 11, as shown in FIGS. 1 and 5, has front and rear sides opposite to each other in the axial direction Y of the cable hole 101. The positioning protrusion 33 has a positioning surface 33a, as shown in FIG. 1, perpendicular to the axial direction Y of the cable hole 101, which is pressed against a front side of the fixing component 11 to position the fixing component 11 in the axial direction Y.
As shown in FIGS. 1 and 9, in the illustrated embodiment, a pair of upper guide ribs 34 are formed on the inner wall surface of the upper side of the installation port 30 of the housing 3. The pair of upper guide ribs 34 extend along the axial direction Y of the cable hole 101 and are adapted to cooperate with a pair of guide slots 114 on the fixing component 11 to guide the fixing component 11 to be inserted into the installation port 30 of the housing 3 along the axial direction Y of the cable hole 101.
As shown in FIGS. 1 and 5, in the illustrated embodiment, the fixing component 11 has front and rear sides opposite to each other in the axial direction Y of the cable hole 101, and the housing 3 has front and rear ends opposite to each other in the axial direction Y of the cable hole 101. When the cable fixing device 1 is installed into the installation port 30 of the housing 3, as shown in FIGS. 2-3, 9, and 12, the rear side of the fixing component 11 is flush with the a rear end face of the housing 3.
The connector is now described in more detail in reference to FIGS. 1-12. The connector, as described above, comprises the connector housing assembly, the multiple terminals, and the multiple cables 2. The multiple terminals are provided in the housing 3. The multiple cables 2 are electrically connected to the multiple terminals. The multiple cables 2 pass through the multiple cable holes 101 of the fixing component 11 and are locked to the fixing component 11 by the locking component 12. In this way, the amount of shaking of the cable 2 can be reduced, ensuring that the position of the terminal does not move and ensuring reliable electrical contact between the terminal and a mating terminal.
As shown in FIGS. 1-3, 8-9, and 11-12, in the illustrated embodiment, the multiple cables 2 are arranged in multiple rows and columns.
In the aforementioned exemplary embodiments according to the present invention, the cable fixing device has a simple structure, reduces costs, and can be used to fix multiple rows and columns of cables, expanding its application range.
