Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a casing end for fixing an end portion of a control cable such as an accelerator cable, a handbrake cable, a hood cable or the like to a panel.

2. Description of the Related Art Conventionally used casing ends include those shown in FIGS. 6 to 8 (as a casing end using such a casing end, it is disclosed in JP-A-59-34383). Something like was done).

FIG. 6 shows a casing end 30 made of zinc die casting for fixing the control cable 10 to the panel 20 shown in FIG.
Is shown. The end portion of the casing 12 through which the inner cable 11 is inserted is fitted into a holding hole 31a provided in a holding portion 31 of the casing end 30, and is caulked and locked from the outside. In addition, a sliding hole 32a through which the inner cable 11 penetrates is provided in a fixed portion 32 that is provided in series with the holding portion 31.
Are formed so as to communicate with the holding hole 31a.

Further, the casing end 30 is fitted and fixed in the cutout portion 21 formed in the panel 20. The two flanges 33, 34 provided on the outer periphery of the fixed portion 32 are fitted into the cutout portion 21.
It is the insertion groove portion 35 located between the.

FIG. 8 shows a resin casing end 40. The casing end 40 has the same structure as the casing end 30 shown in FIG. 6 except that a metal ring 42 is provided on the outer periphery of the holding portion 41 for crimping the casing 12.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the case of the zinc die-cast casing end 30 as described above, in order to secure the fixation to the panel 20, an auxiliary means such as a clip is used, or it is press-fitted with a hammer or the like. There was a need. For this reason, there is a problem that the number of parts and the number of assembling steps are large and the workability is poor.
In addition, corrosion may occur at the joint between the panel 20 and the casing end 30, and the panel may be thinned by rust.
The fixing strength between the casing 20 and the casing end 30 sometimes decreased.

In order to solve such a problem, a resin casing end 40 as shown in FIG. 8 is also considered. In such a casing end 40, rust does not occur at a joint portion with the panel 20, and when assembled to the panel 20, since elasticity of the resin itself can be used, auxiliary means such as a clip is not necessary. However, the flexibility of the resin itself may deform or damage the casing end 40,
The panel 20 cannot be securely fixed, and the operation by the control cable 10 may be hindered. Also,
In order to lock the casing 12, a metal ring 42 has to be used, and in terms of the number of parts and workability, there is no difference from the casing end 30 made of zinc die casting. Further, there is also one in which a resin layer is formed around the outer circumference of the insertion groove portion 35 shown in FIG. 6 to insulate the panel 20. However, in this type, there is a possibility that the resin layer may come off from the fixing portion 32 due to deformation of the resin layer over time. Further, since the inner cable 11 made of metal and the inner peripheral surface (metal surface) of the sliding hole 32a are in direct sliding contact with each other, the inner cable 11 is rusted or damaged, which causes deterioration of the inner cable 11 with time. There is a risk. Although a material using rubber instead of the resin layer has been created, the situation is the same.

OBJECT OF THE INVENTION The present invention has been made in view of the above problems,
(EN) A casing end capable of preventing deterioration of an inner cable over time without increasing the number of parts or the number of assembly steps, and maintaining high fixing strength with a panel without lowering the strength of parts themselves. The purpose is to

Means for Solving the Problems In order to achieve the above object, the present invention has a resin layer for insulating a metal casing end base part from the panel in an insertion groove part inserted into a cutout part formed in the panel. The resin layer is formed with a fitting groove portion that fits in the peripheral edge of the cutout portion of the panel, and the sliding hole formed in the fixing portion of the casing end for sliding the inner cable and the It is characterized in that it is communicated with the insertion groove portion through a communication hole, and the resin layer is integrally extended through the communication hole to the entire inner peripheral surface of the sliding hole.

Action Since the present invention employs the above configuration, it has the following actions. In other words, a resin layer that insulates the panel from the metal casing end base is formed in the insertion groove portion that is inserted into the cutout portion, and the resin layer has a fitting groove portion that is fitted to the peripheral edge of the cutout portion of the panel. Since it is separately formed, the metal casing end base itself does not directly bear the fixing strength with the panel, but the resin layer relieves the burden. Moreover, since the inner cable slides, the sliding hole formed in the fixed portion of the casing end and the insertion groove are communicated with each other by the communication hole, and the resin layer passes through this communication hole and covers the entire inner peripheral surface of the sliding hole. Since it is integrally extended up to, the load applied to the fitting groove of the resin layer due to rattling of the casing is propagated to the resin layer on the inner peripheral surface side of the sliding hole, and the load is concentrated in the fitting groove. It is possible to avoid this. Therefore, the fixing strength with the panel can be maintained for a long period of time. At the same time, since the resin layer is extended over the entire inner peripheral surface of the sliding hole that is in sliding contact with the sliding inner cable, the inner cable slides in contact with the surface of the resin layer, and It is also possible to prevent deterioration.
