Description

[Detailed Description of the Invention] <<Technical Field of the Invention>> This invention relates to a cord clamp for a vehicle lamp. More specifically, the present invention relates to a cord clamp provided on a synthetic resin base such as a lamp body or a back cover of a vehicle lamp.

≪Prior Art≫ Rear combination lamps, which are generally installed on automobiles among vehicular lamps, are equipped with multiple types of lamps such as cross-clamps, tail and stop lamps, turn signal lamps, etc., and power is supplied to the light source bulbs of these lamps. Therefore, a large number of cords are arranged on the back of the lamp body and on the inside of the back cover. If these many cords are not arranged in an orderly manner, they may get caught between other parts during assembly of the lamp, causing damage to the cords, resulting in shortcuts, or interfering with assembly. Further, when taking things in and out of the trunk room, there is a risk that the cord may be caught and broken, making it impossible to turn on the light and causing an accident such as a rear-end collision. Therefore, a conventional practice has been to provide a cord clamp on the lamp body or back cover, and to insert and hold the multiple cords into the cord clamp.

For example, in the conventional cord clamp shown in FIGS. 6 and 7, holding pieces 2, 2 each having a hook-shaped cross section are mounted on a synthetic resin base 1 such as a lamp body or a back cover, with their upper end protrusions facing each other. It is erected. A cord 3 is inserted into the gap between the upper end protrusions of the holding pieces 2, 2 and held in the space between the holding pieces 2, 2. FIG. 7 shows a cross section in which the cord 3 is inserted into the gap between the upper end protrusions of the holding pieces 2, 2, in which the width l of the gap between the holding pieces 2 and 2 is slightly narrower than the diameter L of the cord 3. , the cord 3 is prevented from slipping out from the holding space. In reality, for example, the diameter L of the cord 3 is 2.2 mm, while the gap width l is designed to be 1.5 mm. Therefore, when clamping the cord 3 to the holding pieces 2, 2, by pressing the cord 3 against the gap l and pushing it strongly, the holding pieces 2, 2 are bent and expanded to allow the cord 3 to be inserted. are doing.

<<Problems to be solved by the invention>> However, in order to bend and expand the holding pieces 2, 2 as described above, the cord 3 must be pushed in extremely strongly, which reduces the workability of the clamp. The problem was that it had decreased significantly.

Further, in such a cord clamp, it is necessary to attach each cord 3 one by one, which further reduces work efficiency.

Another problem is that the holding pieces 2, 2 deform over time due to the heat of the lamp, and the space between the holding pieces 2, 2 expands, making it easy for the cord 3 to come off due to vibrations or the like.

≪Means for solving the problem≫ Therefore, in order to solve the above-mentioned problems, the cord clamp of the present invention has a longitudinal clamp installed on a synthetic resin base in the vicinity of the cord placement position. a member, and a locking portion provided at the tip of the longitudinal member,
The cord clamp is adapted to be engaged with an engaging portion formed on the opposite side of the longitudinal member across the cord placement position of the base body, wherein the engaging portion is formed to bulge out on the side of the longitudinal member. On the other hand, the engaging part is characterized by having a through hole formed at an angle or perpendicular to the locking part and through which the locking part is inserted.

<<Operation>> When the locking part is twisted and inserted into the through hole of the engaging part,
This locking part is held in a state shifted from the through hole on the back side of the base by the elastic force of the longitudinal member, and engages with the engaging part to bridge the longitudinal member over the base.

<<Embodiment>> FIG. 1 is a perspective view showing an embodiment of the present invention. The cord clamp according to this embodiment is formed by integral molding on a base body 4 made of elastic synthetic resin such as polypropylene, and includes a longitudinal member 5 erected on the base body 4 and a longitudinal member 5 erected on the base body 4.
, and an engaging portion 7 formed on the opposite side of the longitudinal member 5 across the cord placement position of the base body 4 .

The longitudinal member 5 is formed into a rod shape with a rectangular cross section, and can be elastically bent freely.

Further, in this example, the locking portion 6 is formed into a rod shape with a substantially rectangular cross section that is substantially parallel to the upper surface of the base body 4,
The intermediate portion is connected to the tip of the longitudinal member 5, and both ends bulge out to the sides of the longitudinal member 5. In this example, the locking portions 6 are connected with one end thereof facing toward the engaging portion as shown in FIG.

In this way, the longitudinal member 5 and the locking portion 6 are formed into a substantially T-shape as a whole.

Further, the engaging portion 7 is provided with a through hole 8 through which the locking portion 6 is inserted. This through hole 8 is
It is formed so that its long axis is along the arrangement direction of the cord 3, and is formed to be substantially perpendicular to the locking part 6.

In such a cord clamp, when the locking part 6 is twisted and inserted into the through hole 8, the locking part 6 penetrates on the back side of the base body 4 due to the elastic force of the longitudinal member 5, as shown in FIG. The longitudinal member 5 is held in a state offset from the hole 8 by approximately 90 degrees, and is engaged with the side edge of the through hole 8 so that the longitudinal member 5 can be spanned over the base 4 to clamp a plurality of cords 3 at once. .

FIG. 4 shows a state in which the cord clamp having the above-mentioned structure is applied to the cord placement position of the back cover 10 of a vehicle lamp. There is. This back cover 10 is integrally formed with a pair of socket holders 12 to which lamp bulbs 11 are respectively attached, and a plurality of cords 3 pulled out from these socket holders 12 are collectively clamped by a cord clamp.

Moreover, FIG. 5 is a perspective view showing another embodiment of the present invention. The cord clamp according to this example has a locking portion 13 formed along the arrangement direction of the cord 3.
and a through hole 14 perpendicular to the direction in which the cord 3 is disposed, and as in the previous embodiment, the through hole 1
The locking part 13 inserted through the cord 4 is engaged and held in a state shifted by approximately 90 degrees with respect to the through hole 14 by the elastic force of the longitudinal member 5, and the plurality of cords 3 are clamped by the longitudinal member 5. .

Furthermore, the present invention is not limited to the embodiments described above, and can be modified in various ways. For example, in the embodiment described above, the locking part and the through hole are made perpendicular to each other, but the locking part and the through hole are formed at a certain angle of inclination to each other within a range where the locking part can engage with the engagement hole. It may have a structure that is

≪Effects of the invention≫ According to the invention, multiple cords can be easily attached all at once without having to be forcefully pushed in or attached one by one, which greatly simplifies the clamping work. It can be achieved.

Also, unlike conventional models, the gap between the holders for attaching the cord does not face into the lamp chamber.
There is no risk of the cord falling out from this gap.
