Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a connector fixing body, more specifically a connector that can selectively select an arbitrary connection direction and fix the connector on a panel with a single operation. Regarding fixed bodies.

Electrical machines of various types, such as copying machines and computer terminal equipment, have many electrical and mechanical physical functions, such as sensors, voltage converters, relays, clutches, solenoids, and motors. Functional components (hereinafter referred to as electrical components) are built into a single casing, and these electrical components are fixed onto a plurality of boards or panels within the casing with screws or the like. Conventionally, after all of these electrical components are fixed and assembled in their respective positions on multiple panels within the housing, a single wire is used to electrically connect all or most of the electrical components to each other. There is a method of making electrical connections by crawling the main wire harness into the housing and manually fitting the numerous connectors provided on each part of the wire harness into the corresponding connectors provided on the electrical components. This is commonly done. According to this conventional method, the electrical components are assembled on one side of the housing or multiple panels within the housing, and the wiring harness is routed around the other side of those panels and secured in places with nylon clamps. Fix it to the panel, guide the wire harness to the next panel surface, and then crawl to the next panel and fix it in the same way. In addition, many of the connectors installed in various parts of the wiring harness are not fixed to the panel near the electrical components to be connected, and the ends of the wiring harness are tied free and the connectors are suspended in the air, allowing manual operation. Connect to the corresponding electrical component connector. Therefore, if a large number of connectors with the same number of pins are used in a housing that is packed with intricately packed electrical components, there is a possibility that the connectors will be connected incorrectly. There is a problem with efficiency in this regard, and it is desired to reduce the number of man-hours in the assembly process.

In contrast to such conventional methods, a wire harness is first mounted on the same surface as the panel surface on which electrical components are fixed, and after the connector provided on the harness is fixed at a predetermined position on the panel, There are advantages to assembling electrical components. In other words, when installing an electrical component in a predetermined position on a panel, the positions of both connectors should be determined in advance so that the connector on the electrical component will fit and connect with the connector on the harness that has already been wired. , the efficiency of equipment assembly is improved, and the problem of incorrect wiring can also be avoided. The present invention relates to a connector fixing body used in this type of device assembly, and by using the connector fixing body of the present invention, it is possible to use one main wire harness in one electrical machine as in the past. Rather than crawling around, the wire harness can be installed separately for each panel, and the connection of the entire wire harness can be easily and simply completed at the same time as the panels are assembled.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a novel connector fixing body for simultaneously completing the mechanical assembly of electrical components within the housing and the electrical connection of those electrical components when assembling an electrical machine. It is in.

The present invention will be described below with reference to the drawings. For convenience, the same reference numerals are used to refer to similar features in each drawing.

In Figure 1, (1) is the housing of the insulation displacement connector (10) made of an insulating material such as plastic, and (2) is a group of round wires representing one end of the Hawaiian harness, which are connected to the insulation displacement connector. The connection direction of the connector is indicated by an arrow (A).

(3) is a connector fixing body of the present invention that is assembled by fitting into the housing (1), and is integrally molded from an insulating material such as plastic. (4) and (5) are grooves (6) and (7) provided in the housing so that when the connector fixing body (3) is fitted with the housing (1), the two are integrally assembled and fixed. ) are respectively engaged with the protrusions. The reference numeral (13) indicates a part of the panel for mounting electromechanical parts, connectors, etc.

A pair of protrusions (11) provided on one outer surface of the connector fixing body (3) are press-fitted into a corresponding pair of openings (12) provided on the panel (13) with one touch to fix the connector. These are fixed legs for fixing the body to the panel. FIG. 2 shows a connector (2o) having the same structure as the connector shown in FIG. 1, and the connection direction of the connector is indicated by an arrow (B). The two-dot chain line (24) is the pile surface on which electrical parts, wire harnesses, etc. are to be assembled, and (23) is the connector (20).
The figure shows a fixing body for fixing the panel to the panel, and a pair of fixing legs (
11) is provided. Here, the fixed body (3
) and the fixed body (23) in Figure 2, it is found that when the fixed body and the connector housing are combined, the connection direction (A) of the connector in Figure 1 is parallel to the panel surface. It should be noted that the fixing legs are shaped in such a way that the connection direction (B) is perpendicular to the panel, whereas the connector in FIG. . As described above, there is an important relationship between the connecting direction of the connector and the direction of the fixed legs of the fixed body of the present invention, which will be explained in detail later. In Figure 3, the installation indicated by the two-dot chain line is for the panel (31) and the wire harness (4).
2) is a perspective view showing the relationship with the connector assembly incorporated in 2), and shows that there are two types of connection directions of the connector and two types of press-fitting directions of the fixed legs as described above, and the reference numeral (8)
) shows an example in which two pairs of fixed legs are provided.

Referring to FIG. 4, one wire harness (42), a number of connectors (43) provided on the harness,
It is shown that (44), (45), etc. are mounted on one side of one panel (lO). Similarly, another harness (51) and its connectors (47), (48), (49), etc. are mounted on one side of another panel (41). Electrical components such as sensors, relays, motors, and printed circuit boards will be installed on this panel. for example,
If the connector (45) is a connector for a relay, electrical connection and mechanical assembly can be completed by simply plugging in the plug connector of the integrally assembled relay. Also, for example, when mounting and fixing a small motor on a panel (lO), it is possible to design the motor by aligning the position of the motor connector when the motor is assembled into the panel with the fixing position of the harness connector in advance. , mechanical assembly and electrical connection of the motor to the housing can be completed in one operation. Furthermore, in Figure 4, the panel (
When the two panels are assembled by inserting the claw (52) provided on the panel (10) into the opening (53) made in the panel (41), the connector (44) on the panel (10) and the panel (
41) Since the connector (47) on the top is fixed in a pre-aligned position, the electrical connection between the two panels is achieved at the same time as the two panels are assembled, and the wiring between the two is integrated.

By assembling panels one after another in this way, the individual wiring on the panels is networked, and the main wire harness is finally completed.

As can be understood from Fig. 4, when implementing such an arrangement, the insertion direction of the connector, that is, the connection direction of the connector and the panel surface are at least two types of directions (hereinafter referred to as connector directionality). have. In other words, when fixing the connector provided on the wire harness to the panel, the connection direction needs to have two types of directionality: parallel or perpendicular to the panel surface, and the present invention The orientation of the connector can be easily determined using a fixing body with an extremely simple structure.

Conventionally, when mechanically fixing a connector to, for example, a printed circuit board, the mounting 7 langes or mounting claws were molded integrally with the connector housing, so the orientation of the connector was unique during the manufacture of the connector. It was fixed and uniquely determined as a thing. According to the prefabricated connector fixing body of the present invention, it is possible not only to fix the directionality of connectors of the same type with the same number of poles, pitches, etc. with one touch using extremely simple means, but also to fix the directionality of connectors with the same number of poles, pitches, etc.
Even when installing a wire harness that has many connectors with different numbers of pins, if the external dimensions of the connector housings are kept within a certain range, it is possible to connect many types of connectors with a small number of connector fixing bodies. The direction can be changed selectively. In addition, since the connector is pre-positioned and fixed on the panel, there is no chance of incorrect connection with electrical components.
It can also be used as a wire harness clamper.

As already mentioned, Fig. 1 shows the connector fixing body when the connector connection direction is parallel to the panel surface, and Fig. 2 shows the case when the direction is perpendicular to the panel surface. In the figure, a pair of sloped protrusions (4) and (5) are connected to the groove (6) on the housing side on the carp/lid fixing body side.
and (7), but it is obvious that a protrusion may be provided on the housing side and a groove may be provided on the fixing body side, or other methods of fixing with one operation. Therefore, no further explanation is necessary. Also, Figure 1 or Figure 2
In addition to the fixed leg (11) of the fixed body shown in the figure, the fixed leg (11)
A plane that intersects with the plane in which is provided, for example, the plane in Fig.
FIG. 5 shows another embodiment in which the connecting direction of the connector can be changed to two directions with one type of connector fixing body by providing another set of fixing legs (15) to the connector fixing member 14). Although the press-fit type connector has been illustrated and explained, it is clear that the present invention has similar effects on the press-fit type connector. When the present invention is applied to a pressure welding type connector, as shown in the cross-sectional view of FIG.
It should be noted that a plurality of protrusions (16) matching the number of r can be provided and used as a press-fit jig for the round wire, and also that it can be used as an insulating cover to prevent short-circuiting of the core wire on the cut surface of the round wire. Should.

In addition to the effects described above, the fixing body of the present invention has a simple structure and can easily fix the directionality of the connector on the panel, so the number of types of connectors to be incorporated into the wire harness does not increase, and the number of connectors is small. This makes it possible to mass-produce various types of wire harnesses, and also to save a lot of labor in the production and assembly of wire harnesses.
