Field of the Disclosure
The present disclosure relates to a hook terminal configured to tie several strands of cable.
Discussion of the Related Art
Generally, cables on a vehicle or an electronic device for power connection are complicatedly wired. A cable fixing (tying) device is disposed for collecting complicated wirings and fixing the wirings to a support body.
A conventional cable fixing device largely uses an elastic clip secured to a main body side, where a cable of several strands is inserted into an insertion groove, and the cable is pressed using an elastic body to fix the several strands.
The conventional cable fixing device is problematic in that the elastic clip fixes the cable using an elastic force thereof to cause the cable to be disengaged from the elastic clip due to external shock. Another problem is that as the use time increases, the elastic force decreases to reduce a cable fixing power.
The present disclosure is directed to cope with the abovementioned problems and to provide a hook terminal configured to firmly fix a cable and to inhibit the cable from moving to an axial direction.
Technical problems to be solved by the present disclosure are not restricted to the above-mentioned description, and any other technical problems not mentioned so far will be clearly appreciated from the following description by the skilled in the art.
In one general aspect of the present disclosure, there is provided a hook terminal, comprising: a hook unit formed with an upper side-opened fixing groove into which a cable of several strands can be inserted; a fixing unit integrally formed with a bottom side of the hook unit and fixed to a main body; a cable disengagement prevention unit formed at an upper end of the hook unit to inhibit the cable from being disengaged; and a plurality of pressure lugs formed at the hook unit to inhibit the cable from moving to an axial direction by applying pressure to an external surface of the cable.
In another general aspect of the present disclosure, there is provided a hook terminal, comprising, a hook unit formed at an upper side with an opening capable of inserting at least two cables, where the other end of the opening is formed with a fixing groove in which inserted cables are accommodated; a fixing unit integrally formed at a bottom side of the hook unit to be fixed at a main body when the main body is formed by injection molding; a disengagement prevention unit formed at a vicinity of the opening formed at the upper side of the hook unit to inhibit the cable from being disengaged; and a plurality of pressure lugs formed at an inner surface of a fixing groove of the hook unit to inhibit the cable from moving to an axial direction by applying pressure to an external surface of the cable.
A hook terminal according to the present disclosure has an advantageous effect in that the hook terminal is formed with a cable disengagement prevention unit fixing a cable by way of hot pressing work to inhibit the cable of several strands from being disengaged and to inhibit the cable from moving to an axial direction.

A hook terminal (10) according to an exemplary embodiment of the present disclosure may be largely used for vehicles, and also employed for other products than the vehicles including a product mounted with a plurality of cables for power connection.
Furthermore, a cable (50) may be applied to a power transfer wire in addition to the power connection purpose. The vehicles and electronic devices are mounted with a plurality of elements that need power, and the cable (50) is used for supplying power to each element. The cable (50) is secured to a main body with a gap formed at a mid section thereof to inhibit the cable (50) from rattling or clattering.
Under this circumstance, a hook terminal (10) according to an exemplary embodiment of the present disclosure is used to secure the cable of several strands.
The hook terminal according to an exemplary embodiment of the present disclosure includes a hook unit (20) formed with an upper side-opened insertion groove (22) into which a cable of several strands can be inserted; and a fixing unit (30) integrally formed with a bottom side of the hook unit (20) and fixed to a main body. The hook terminal (10) is preferably manufactured with a plastic that is injection molded.
The hook unit (20) includes first and second support pads (24, 26), each pad facing the other pad at a predetermined gap, and the insertion groove (22) is interposed between the first and second support pads (24, 26) to allow two or more cables to be inserted thereinto. An inner upper surface of the hook unit (20) faced by the first and second support pads (24, 26) is formed with an inclined surface (28) for easy insertion of cable (50).
Furthermore, a plurality of pressure lugs (40) is formed at the hook unit (20) to prevent the cable (50) from moving to an axial direction by applying pressure to an external surface of the cable (50).
That is, if an upper end of the hook unit (20) is deformed by hot press work while the cable (50) is inserted into the insertion groove (22) of the hook unit (20), the cable (50) can be prevented from being disengaged from the insertion groove (22) but cannot be inhibited from moving to an axial direction of the cable (50). Therefore, the plurality of pressure lugs (40) is formed at an inner surface of the hook unit (20) to prevent the cable (50) from moving to an axial direction by applying pressure to an external surface of the cable (50).
Each of the plurality of pressure lugs (40) is formed in the shape of a gear at an inner surface of the insertion groove (22) of the hook unit (20) to allow gear teeth to be meshed with an external surface of the cable and to apply pressure to the external surface of the cable (50).
Alternatively, each of the plurality of pressure lugs may be formed in a plurality of convex lugs on the inner surface of the insertion groove (22) to apply pressure to the external surface of the cable (50).
The shape of each pressure lug may take any shape as long as it is formed at the inner surface of the insertion groove of the cable (50) to apply pressure to the external surface of the cable (50).
The fixing unit (30) may be fixed to an injection molded body (60) mounted on a vehicle or an electronic device by way of double injection molding method. The fixing unit (30) includes a flange unit (32) accommodate to the injection molded body (60), and an insertion unit (34) that is inserted into the injection molded body (60), and a through hole (36) into which the injection molded body (60) is inserted when the injection molded body (60) is formed.
The fixing unit (30) may be formed by a bolt fastening or bonding method to a structure body in addition to the structure fixed by the double injection molding method.
Now, a cable fixing process of the hook terminal thus configured according to the exemplary embodiment of the present disclosure will be described.
Two or more cables (50) are inserted into the insertion groove (22) of the hook unit (20). At this time, the external surface of the cable is applied with pressure by the plurality of pressure lugs (40) formed at the hook unit (20).
Referring to
As noted above, the hook terminal is such that an upper end of the hook unit (20) is thermally deformed by hot press work to close an opened upper side of the insertion groove (22), whereby the cable (50) is inhibited from being disengaged from the hook terminal (10) by an external shock.
Furthermore, the plurality of pressure lugs (40) formed at the hook unit (20) applies pressure to the periphery of the cable (50) to inhibit the cable (50) from being moved to an axial direction of the cable (50).
Although embodiments have been described with reference to a number of illustrative embodiments thereof, it should be understood that numerous other modifications and embodiments can be devised by those skilled in the art that will fall within the spirit and scope of the principles of this disclosure. More particularly, various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims.
