Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a supporting device for a wire rod or a pipe rod such as an electric wire having a connecting portion.

[0002]

2. Description of the Related Art Conventionally, a large number of supporting members have been used for supporting devices for supporting wire rods such as electric conductors or pipes. Most of them are related to the fixing of highly flexible wire rods, and in the past, they were staples that fixed the wiring to the wall surface, and in recent years, molding materials that bundle and fix the wiring inside the electric equipment, and outside the electric equipment. It is a restraint material to improve the storability of the electric cords that have come out. In addition, there are many restraining materials for bundling and fixing pipe materials such as flexible tubes.

An example of the supporting member is shown in FIG. Figure 9
(A) is for supporting a short pipe having a notch through a wire or the like, and FIG. 9 (B) is for supporting a short rectangular tube whose one surface is releasable through the wire or the like.

Such a supporting member prevents a plurality of wire rods from falling apart, or fixes them so that they are not caught or interfered with other members, especially the operating member. It is very convenient to use.

[0005]

However, the conventional supporting member has the following problems in terms of workability when supporting a wire having high flexibility, particularly a very thin wire.

(1) In a bundle of electric wires having a connector as a connecting portion, the bundle does not have the rigidity required for inserting the connector, and therefore the worker must always carry out the work by holding the connector. However, long connector sizes are extremely rare. For example, as shown in FIG. 10, when the mating connector 4 is in a recessed position and the holes 14 and 13 formed in the drive plate 11 and the main body side wall 12 are smaller than the hands and fingers of the operator, When the operator holds the connector 3 on the insertion side with his / her finger, he / she cannot insert it even though the other connector 4 is visible.

(2) Since the wire rod has a high rigidity in the longitudinal pulling direction, it is necessary to provide a loose margin for the wiring work. However, the conventional restraint member for the wire rod does not remove the slack of the wire rod even if it binds the wire rods, so that the slack remains by that amount.

(3) When the wire is long, heavy, and has a considerable amount of slack, the weight of the wire acts as an external force on the connector due to vibration, which may result in poor connection.

The present invention has been made to solve the above problems, and in particular, protects a wire rod and the like from other members and imparts rigidity necessary for inserting a connecting portion such as a connector. An object of the present invention is to provide a supporting device including a supporting member that applies tension to a wire or the like.

[0019]

Embodiments of the supporting device according to the present invention will be described below with reference to the drawings. (First Embodiment) FIGS. 1 to 3 show a first embodiment of the present invention. 1 is a configuration diagram of the printer main body, FIG. 2 is a configuration diagram of a support member, and FIG. 3 is a mounting diagram of the support member.

In FIG. 1, reference numeral 1 denotes the printer body, which is a state in which the outer cover is not yet attached. A substrate 2 is horizontally arranged in the printer body 1, and a connector 4 is attached to the end of the substrate 2. A drive plate 11 is attached to the printer body 1 at a distance L from the body side wall 12. The gear assembly 16 (only part of which is shown) is housed in this space.
The gear assembly 16 is a motor 1 that is a main motor mounted on the side of the drive plate 11 opposite to the side wall of the main body.
5 drives the rollers and the like provided in the printer body 1.

The present embodiment is an example implemented in a laser beam printer, and the printer body 1 is provided with a scanner motor and a fan motor as drive sources in addition to the motor 15 which is the main motor, and the printer is also provided. It also has the configuration of other parts of the main body 1, paper path, etc.
It is omitted because it is irrelevant to the present invention.

The motor 15 is supplied with electric power from the connector 4 on the substrate 2 in the printer body 1. Therefore, a bundle of conducting wires 6 having the connector 3 on the insertion side at the tip thereof is pulled out from the motor 15. This connector 3 is provided with a hole 14 formed in the drive plate 11.
And the hole 13 formed in the main body side wall 12 of the printer main body 1 to penetrate the holes and the mating connector 4 on the substrate 2 provided in the printer main body 1. The above-mentioned configuration usually has the following problems.

The gear assembly 16, the electromagnetic shield material, and the like are sandwiched between the drive plate 11 and the side wall 12 of the main body, and a very large hole cannot be formed for inserting the connector 3. Further, even if a large hole is opened, it is useless because of the gear assembly 16.

The conducting wire 6 of the motor 15 is connected to the gear assembly 1
Since the wiring is provided in the vicinity of 6, the slack of the conductive wire 6 may be caught in the gear assembly 16.

Since the lead wire 6 is longly arranged, the weight of the lead wire 6 may cause the connector 3 to come off when vibration is applied.

Since the conductive wire 6 is distributed through the edge of the sheet metal, the conductive wire 6 is damaged, and there is a possibility of disconnection or short circuit with the grounded sheet metal.

The support member 5 according to the support device of the present invention, which solves the above problems at once, will be described mainly with reference to FIG.

The support member 5 holds the connector 3 by light press-fitting, and covers the conducting wire 6 with a covering portion 53 as a holding portion, an arm portion 51 as a variable portion, an arm portion 52 as a guide portion, and a connector. 3 is composed of legs 55 and 56 for preventing coming off. The supporting member 5 of this embodiment is constructed as a single component of resin, and nylon resin is used as the resin, so that it has rigidity, toughness, slidability, and heat resistance.

The covering portion 53 is a hollow rectangular tubular portion having a wall thickness of 1 to 1.5 mm, the wall at the tip thereof is notched in one direction, and the connector 3 is lightly press-fit therein. The conducting wire 6 connected to the connector 3 penetrates the hollow portion of the rectangular tubular portion. Since this rectangular tubular portion has sufficient rigidity for compression in the longitudinal direction, the operator holds the portion with his / her finger and pushes it into the connector 3
Can be plugged in. The arm portion 51 is made of a plate-shaped member having a width narrower than that of the rectangular tubular portion of the covering portion 53.
Due to its narrow width, it has low rigidity, but is flexible, tough, and has a restoring force against bending and twisting. Therefore, as shown in FIG. 2, the arm portion 51 is curved and plays a role of adjusting the length of the conductive wire 6 and a role of applying tension to the conductive wire 6 to stabilize it.

The arm portion 52 is composed of a rectangular tubular portion having a length sufficient to guide the conducting wire 6. Although the arm portion 52 and the covering portion 53 are square tubular portions in this embodiment, they may be cylindrical.

The leg portions 55 and 56 are members for fixing the support member 5, and are provided on both sides of the covering portion 53 with inclination. These legs 55 and 56 are also tough,
At its end, a recess 55a, which fits into the notches 17 and 18 of the hole 14 formed in the drive plate 11,
56a is formed. That is, the legs 55, 56
Is slightly narrowed and the recesses 55a, 56a and the notches 17, 18 are engaged with each other, so that the legs 55, 56
By the restoring force of, the support member 5 is fixed to the drive plate 11. Further, by engaging the notches 17 and 18 with the leg portions 55 and 56, the leg portions 55 and 56 also serve as guides when the support member 5 is inserted into the drive plate 11. Since it is not located at the lateral center of 5, the support member 5 is an obstacle when trying to insert it in the left-right direction, which has the effect of preventing reverse insertion.

Further, as shown in FIG. 1, a boss 57 having a notch as a mounting member is provided on the side surface of the covering portion 53 of the supporting member 5, and the boss 57 is attached to the mounting plate 19 of the motor 15. It can be press-fitted into the opened hole 19a. That is, as shown in FIG. 3, by mounting the support member 5 on the mounting plate 19 of the motor 15,
A compact form with excellent transportability can be obtained.
Further, the conducting wire 6 which is an obstacle during the assembly process can be temporarily fixed.

By the support member 5 described above, the conductive wire 6 is protected from the edges of the two sheet metals when penetrating the holes 14 and 13 formed in the drive plate 11 and the side wall 12 of the main body, respectively, and the recessed position is obtained. It is possible to connect the mating connector 4 and the connector 3 on the insertion side, and since the support member 5 is fixed to the drive plate 11 by its legs 55 and 56, for example, the weight of the conductor wire is vibrated. Even if the connector 3 acts in the direction of pulling out the connector 3, it acts as a retainer and retainer, and due to the deformation of the arm 51, a certain amount of tension is applied to the conducting wire 6, so that the conducting wire 6 is positioned at the unnecessary position ( Status)
The supporting member 5 also has a boss 57 on its side surface, and can be held in a form that does not interfere with transportation or the like.
