Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a relay block mounted on an automobile.

[0002]

2. Description of the Related Art Conventionally, a relay block 11 shown in FIG.
0 is suggested. In the relay block 110, the relay 100 is removably mounted on the relay mounting portion 103 provided on the block body 111. When mounting the relay 100, the relay 100 is attached to the relay mounting portion 103.
When the angle is slanted, the connection terminal 101 of the relay 100 is forcibly inserted into the terminal 105 housed in the relay mounting portion 103, and the terminal 105 becomes unsteady. In addition, since the gap into which the connection terminal 101 is inserted into the terminal 105 is set to be extremely small, if the insertion posture of the connection terminal 101 is inclined, the terminal 105 can easily be caught. When the terminal 105 is squeezed, the gap in which the connection terminal 101 is inserted into the terminal 105 becomes wider, so that the contact pressure between the terminal 105 and the connection terminal 101 becomes smaller.

In order to prevent such a problem, FIG.
In the relay block 110 shown in FIG. 8, a frame-shaped hood 1 is provided on the outer wall of the relay 100 so as to surround the connection terminal 101.
02 is provided. According to this configuration, when the relay 100 is mounted on the relay mounting portion 103, the hood 10
Since the mounting of the relay 100 is guided by 2, the insertion posture of the connection terminal 101 with respect to the terminal 105 can be maintained well. As a result, the load is not applied to the terminal connecting portion between the relay 100 and the relay mounting portion 103, and the occurrence of slackening at the terminal 105 of the relay mounting portion 103 is suppressed.

By the way, in recent years, value engineering (VE) has attracted attention as a method for minimizing the essential functions of products and parts, mainly in Europe. From that viewpoint, as the manufacturing cost of the relay 100 is reduced, the relay 106 that does not have the hood 102 tends to be used. However, if the hood 102 is omitted, the function of preventing the terminal 105 from being caught is impaired as described above. Therefore, as shown in FIG. 19, a frame-shaped guide portion 120 corresponding to the hood 102 is provided. , Relay 10
It has been proposed to provide it on the block body 111 instead of 6.

In such a guide portion 120, the relay 10 is opened from the relay insertion port 120a opened at the front end side thereof.
6 is inserted. At this time, since the relay 106 is inserted while being guided by the guide portion 120, the terminal 1
The connection terminal 101 is properly inserted into the connection terminal 05, and the terminal 105 is prevented from being jammed.

[0006]

However, if a defective relay is found after checking the operation of the relay box, the relay 106 may be removed from the guide portion 120 in order to replace it. Since the terminals 101 and 105 have a strong contact pressure, the relay 106 cannot be easily pulled out. Moreover, the relay 106 mounted on the guide portion 120
Since the outer peripheral surface of the relay is not exposed to the outside, it is difficult for an operator to grip the relay 106. For this reason,
It was very difficult to pull out the relay 106 mounted on the guide portion 120.

Therefore, in order to facilitate the extraction of the relay 106, as shown in FIG.
By forming the notch 121 in a part of 0, the relay 106
A part of the outer peripheral surface of is exposed so that the relay 106 can be easily gripped. However, since the contact pressure between the connection terminal 101 and the terminal 105 of the relay 106 is very large, it is insufficient to facilitate the extraction of the relay 106. Also,
Enlarge the notch area of the guide part 120 to increase the relay 1
Although it is conceivable to improve the ease of grasping 06, the strength of the guide portion 120 is reduced, and thus the function of inserting and guiding the relay 106 is reduced.

As a related technique for facilitating the removal of the relay 106, a conventional technique is known in which electric functional parts other than the relay 106 can be easily removed. For example, a fuse extraction structure is disclosed in Japanese Patent Laid-Open No. 10-25564.
It is disclosed in Japanese Patent No. That is, as shown in FIG. 20, a guide portion 131 recessed in the fuse mounting portion 130.
The wire 132 is inserted into the wire 132, and the end 132a of the wire 132 is passed through the lower side of the fuse 134 and folded back to the outside of the guide 131. Then, the wire rod 13 extracted from the guide portion 131
The fuses 134 are pulled out by bundling both ends of 2 and pulling them up.

However, according to this method, the fuse 1
Since the wire 34 is held only by the wire 132 and is pulled upward, the withdrawal posture of the fuse 134 becomes unstable. Therefore, when the fuse 134 is forcibly pulled out from the fuse mounting portion 130, the terminal 105 may be broken.

Further, a structure in which a fuse puller for facilitating the removal of a fuse is attached to a junction block is disclosed in Japanese Utility Model Publication No. 5-53106. As shown in FIG. 21, the fuse puller mounting portion 140
Is a quadrangular frame-like body, and a slide mold punching hole 141 is formed at the lower end of the center thereof. It is conceivable to use the structure corresponding to the fuse puller mounting portion 140 as the guide portion of the relay described above. However, since the usage methods of the fuse puller and the relay are completely different, for example, in the fuse puller 142, most of the fuse puller 142 is projected from the fuse puller mounting portion 140 in order to improve the detachability. However, like the fuse puller 142, if a structure in which most of the fuse is projected from the guide portion is adopted, the guide function when mounting the fuse is significantly reduced as described above. Therefore, the structure of the fuse puller mounting portion 140 is changed to the guide portion 12
It cannot be applied to 0.

The present invention has been made in view of the above problems, and an object thereof is to provide a relay block in which a relay can be easily removed from a guide portion.

[0012]

In order to solve the above-mentioned problems, in the invention according to claim 1, a block main body having a terminal housing for accommodating a crimp terminal therein is provided, and a connection terminal is provided in the block main body. A relay that connects a connection terminal to the crimp terminal by providing a frame-shaped guide portion having an insertion port into which the relay having the above is inserted, and inserting the relay into the inside through the insertion port of the guide portion. A gist of the block is that a jig insertion portion is formed on a side wall of the guide portion near a boundary portion between the terminal housing and the relay.

According to this structure, the tip of the jig is inserted into the boundary between the terminal housing and the relay from the jig insertion portion,
When the jig is operated to lift the relay from the terminal housing, the relay is guided by the guide portion and protrudes from the relay insertion port. As a result, the pressure contact force between the connection terminal and the crimp terminal is reduced, and the relay can be easily pulled out.

According to a second aspect of the present invention, in the first aspect of the invention, the side wall of the terminal housing is exposed at a part of the outer wall of the block body in the vicinity of the jig insertion portion. The gist of the invention is that the outer wall of the block body is formed with a missing portion, and the end portion of the jig insertion portion is open so as to communicate with the missing portion.

According to this structure, even if the installation direction of the relay block differs depending on the vehicle model, it is possible to insert the jig into the jig insertion portion from multiple directions via the cutout portion.
According to a third aspect of the present invention, in the first or second aspect of the invention, the width of the terminal housing is formed to be narrower than the width of the relay.

According to this structure, since a part of the relay projects from the side surface of the terminal housing, the jig can be pressed against the projecting part to widen the gap between the terminal housing and the relay. it can. Therefore, the jig can be easily inserted at the boundary between the relay and the terminal housing.

According to a fourth aspect of the invention, in the invention of the third aspect, the width of the terminal housing is gradually narrowed toward the guide portion side end portion of the terminal housing. The gist of this is that an inclined surface is provided.

According to this structure, at the end of the terminal housing, the width of the terminal housing is gradually narrowed toward the guide portion side, so that the tip of the jig is guided to the surface of the relay on the terminal housing side. It's getting easier. Therefore, the tip of the jig can be easily brought into contact with the terminal housing side of the relay.

According to a fifth aspect of the present invention, in the invention according to any one of the first, third and fourth aspects, the block body faces the jig insertion portion, The gist of the invention is that a protrusion is provided at a predetermined distance from the jig insertion portion.

According to this structure, the tip of the jig is inserted into the boundary between the terminal housing and the relay while the elongated jig such as a flat-blade screwdriver is applied to the protrusion. In this state, when the jig is rotated with the protrusion as the rotation fulcrum, the relay is projected from the guide portion by the lever principle. Therefore, the relay can be lifted up from the terminal housing with a smaller force.

According to a sixth aspect of the present invention, in the invention according to any one of the first to fifth aspects, an end face of a terminal housing having a terminal insertion cavity into which the connection terminal of the relay is inserted is provided. The gist of the present invention is to provide an insertion restriction protrusion to which the inner end surface of the relay inserted in the guide portion abuts.

According to this structure, when the relay is inserted in the guide part, the inner end surface of the guide part is abutted by the insertion restricting projection, and a gap is formed at the boundary between the relay and the terminal housing. Becomes Therefore, the presence of the gap prevents the jig from being forcibly inserted into the boundary portion between the relay and the terminal housing.

The relay 30 can be lifted.

The third embodiment of the present invention may be modified as follows. The shape of the protrusion 50 provided on the block body 11 may be a shape other than a triangular prism. For example, as shown in FIGS. 14 and 15, the shape of the protrusion 51 may be changed to a triangular pyramid shape with a rounded tip. In this case, the lever principle can be utilized by bringing the tip of the jig 5 into contact with the surface of the relay 30 on the side of the terminal housing 13 and using the contact point between the jig 5 and the protrusion 51 as a fulcrum. In addition, since the fulcrum that supports the jig 5 is the apex of the triangular pyramidal protrusion 51, the tip of the jig 5 can be moved freely, which facilitates the operation for lifting the relay 30. Fourth Embodiment As shown in FIGS. 16 and 17, the end face of the terminal housing 13 is provided with an insertion regulation protrusion 60 against which the inner end face of the relay 30 mounted on the guide portion 20 abuts.
