Fig. 4 shows relay attachment 18a, and Fig. 5 and 6 shows relay attachment 18b and 18c simultaneously.Because these relay attachment 18a, 18b have identical structure substantially with 18c, so below will mainly describe the representative of relay attachment 18a as them.Relay attachment 18a is suitable for admitting the electric component such as relay 28.Terminal 32 (Fig. 6) is outstanding from the main body 30 of this relay 28.Relay attachment 18a is provided with terminal insertion hole 34, this terminal insertion hole 34 with terminal 32 corresponding position openings so that terminal 32 therefrom passes.

For the fuse and the relay 28 that are installed in respectively on fuse attachment 16 and the relay attachment 18, the attached and detaching direction of the direction vertical (vertical direction up and down among Fig. 3) expression with the extension direction of upper surface 14.Near the attached direction of the direction indication of main body 12, and fuse and relay 28 leave the direction indication detaching direction of main body 12 along the direction vertical with the extension direction of upper surface 14 for fuse and relay 28.

The relative position place of relay attachment 18a on outer peripheral portion is provided with pair of engaging protrusion tab 36, and this is integrally formed and 14 outstanding along detaching direction from upper surface to engaging protrusion tab 36 and main body 12.Especially, in the present embodiment, each engages that protrusion tab 36 is arranged on the substantial middle part of relay attachment 18a and longitudinally on two end opposite.Each engages protrusion tab 36 and all forms the door shape framework of giving prominence to from upper surface 14.Because its elasticity, engaging protrusion tab 36 can be along its thickness direction (above-below direction among Fig. 4) strain.As shown in Figure 6, set according to the formation position of the copulational protuberance 37 of relay 28 and to engage the outstanding size of protrusion tab 36 from upper surface 14, promptly height H 1.Particularly, in the present embodiment, copulational protuberance 37 is arranged on each side surface 38 of relay 28.Set to engage the outstanding size (being height H 1) of protrusion tab 36, make that joint protrusion tab 36 does not extend beyond the upper surface 39 of relay 28 when relay 28 is installed in relay attachment 18a and goes up.

In addition, be provided with guiding wall 40 on each relay attachment 18 each in four bights, this guiding wall 40 is outstanding and integrally formed with main body 12 from upper surface 14 along the detaching direction of relay 28.In top plan view, each guiding wall 40 all forms L shaped structure.Therefore, between the guiding wall 40 relative, be formed with side opening 42, make the lateral opening of this side opening 42 in relay attachment 18 along the longitudinal direction of relay attachment 18.Each side surface 38 of relay 28 by each side opening 42 to exposing outside, thereby relay 28 easily can be attached to relay attachment 18 and separate from this relay attachment 18.Especially, the end edge portion of the formation side opening 42 of guiding wall 40 tilts along the projected direction of guiding wall 40, makes side opening 42 broaden along with the jag of its close control wall 40.

As shown in Figure 6, guiding wall 40 is set at the height that equals the upper surface 39 of relay 28 when relay 28 is installed on the relay attachment 18 substantially from the outstanding size (being height H 2) of upper surface 14.Especially, in the present embodiment, this outstanding size (being height H 2) is set to and is lower than upper surface 39 slightly.

As shown in Figure 5 and Figure 6, relay attachment 18b is disposed adjacent one another along the direction vertical with the longitudinal direction of upper surface 14 with 18c.In top plan view, the adjacent guiding wall 40 of relay attachment 18b and 18c constitutes the both sides of T shape midfeather 46.

In addition, between the guiding wall 40 relative, be provided with stop 48 with the vertical direction of the longitudinal direction of relay attachment 18a.Stop 48 is outstanding from upper surface 14 along the detaching direction of relay 28.Stop 48 is with integrally formed along the relative a pair of guiding wall 40 of the direction vertical with the longitudinal direction of relay attachment 18a.Two guiding walls 40 are connected to each other by stop 48.Each stop 48 all engages the outside of protrusion tab 36 along the longitudinal direction of relay attachment 18a with each spaced apart.

As shown in Figure 6, stop 48 is set to less than engaging the outstanding size (be height H 1) of protrusion tab 36 from upper surface 14 from the outstanding size (being height H 3) of upper surface 14.Preferably, this outstanding size (being height H 3) is set to substantially less than 2/3rds (2/3) of the outstanding size (being height H 1) that engages protrusion tab 36.Therefore, the outstanding size of stop 48 (being height H 3) is set to the outstanding size (being height H 2) less than guiding wall 40.Especially, the outer surface that is arranged in stop 48 (the top stop 48 among Fig. 4 and the stop 48 at the two ends up and down among Fig. 5) and main body 12 on the outer circumferential side of main body 12 forms at grade.

When clamped nipple is inserted into when being fixed to main body 12 main body 12 and by locking mechanism from opposition side (lower face side of main body 12), described clamped nipple is received and is fixed in the terminal insertion hole 34 in fuse attachment 16 and the relay attachment 18.

As above the relay box 10 of Gou Chenging can be received in fuse and relay 28 in fuse attachment 16 and the relay attachment 18 with removably as required.

For relay 28 is installed on the relay attachment 18, at first with the main body 30 of relay 28 from terminal 32 1 side setting-ins to guiding wall 40.Then, guiding wall 40 guide main bodies 30 make main body 30 near upper surface 14, and terminal 32 are inserted in the terminal insertion hole 34.Next, when main body 30 during further near upper surface 14, engage protrusion tab 36 and once be out of shape along the direction of leaving relay 28, turn back to initial position and be locked on the copulational protuberance 37 thereby engage protrusion tab 36 then because of the copulational protuberance 37 on the side surface 38 that is arranged on main body 30.When copulational protuberance 37 lockings engage protrusion tab 36, because stop 48 is outwards spaced apart from engaging protrusion tab 36, so allow to engage protrusion tab 36 along the direction distortion of leaving relay 28.Therefore, main body 30 is fixed to relay attachment 18 by engaging protrusion tab 36, and terminal 32 is electrically connected with clamped nipple in being arranged in terminal insertion hole 34.

When relay 28 was installed on the relay attachment 18, pair of engaging protrusion tab 36 was positioned on two opposition sides of relay 28, and a pair of stop 48 is with to engage protrusion tab 36 spaced apart, and relative with relay 28 across engaging protrusion tab 36.

When relay 28 is installed on the relay attachment 18, by guiding wall 40 in four bights along the main body 30 of protection relay 28 on the entire portion of short transverse.Especially; in the present embodiment; because the outstanding size (being height H 2) of guiding wall 40 equals or be slightly smaller than the height of the upper surface 39 of relay 28 substantially,, and can reduce as much as possible so the outstanding size of guiding wall 40 (being height H 2) can protection relay 28.Except L shaped structure, this can improve the intensity of guiding wall 40.

When relay 28 when relay attachment 18 is separated, shown in the dotted line that the length among Fig. 6 replaces, engage protrusion tab 36, to remove copulational protuberance 37 and the lock-out state that engages between the protrusion tab 36 along the direction strain of leaving relay 28.When discharging joint protrusion tab 36, upwards surpass stop 48 owing to engage the jag of protrusion tab 36, so joint protrusion tab 36 can easily be shifted.

If joint protrusion tab 36 is out of shape in a large number along the direction of leaving relay 28 for relay being attached to relay attachment 18, then engage protrusion tab 36 contact stops 48, further be out of shape thereby prevent to engage protrusion tab 36.This can prevent to engage protrusion tab 36 excessive deformation and surpass regime of elastic deformation in the plastic deformation scope, damages thereby prevent to engage protrusion tab 36.Therefore, can be under the normal mounting state with relay 28 stable maintenance.

In addition, because the outstanding size (being height H 3) of stop 48 is set to less than the outstanding size (being height H 1) that engages protrusion tab 36, even engage near the protrusion tab 36 so stop 48 is arranged in, also can obtain to engage the deflection of protrusion tab 36, thereby can make 18 miniaturizations of relay attachment.Especially, because the outstanding size (being height H 3) of stop 48 is set to the outstanding size (being height H 1) less than joint protrusion tab 36, so can limit of the distortion of the mid portion of joint protrusion tab 36 along projected direction.Therefore, can limit the stress of the near-end that engages protrusion tab 36, wherein, if stop 48 is not set, then the stress major part concentrates on described near-end.Simultaneously, for engaging protrusion tab, can continue further strain from the state that joint protrusion tab 36 contacts the jag of stops 48.This continuation can not concentrate on distortion the near-end that engages protrusion tab 36, and will this engage protrusion tab along positively causing distortion on the mid portion of projected direction or the jag.As a result, by distributed stress and distortion on entire portion in the stress in the near-end that acts on this joint protrusion tab in minimizing, can realize removing the required enough distortion of this joint.

Compare with the situation of the upper surface 39 that engages protrusion tab 36 engage body 30, by joint protrusion tab 36 is engaged with the side surface 38 of relay 28, the outstanding size (being height H 3) of protrusion tab 36 can be reduced to engage, and the height dimension of relay attachment 18 can be limited.Form a shape framework owing to engage protrusion tab 36, so joint protrusion tab 36 is engaged with side surface 38.Owing to the door shape framework that engages protrusion tab 36, the intensity of the proximal end of this joint protrusion tab 36 has reduced, and stop 48 can effectively prevent to engage protrusion tab 36 when making 36 miniaturizations of joint protrusion tab with being combined in of joint protrusion tab 36 and damage.Particularly, in the present embodiment, because stop 48 is connected to guiding wall 40, so these walls 48 and 40 can be brought into play the effect of mutual reinforcement.Therefore, can in the sufficient intensity that obtains stop 48 and guiding wall 40, avoid these walls to maximize owing to thickness increases.

As shown in Figure 5, relay attachment 18b and 18c are disposed adjacent one another.18a is the same with the relay attachment, and relay attachment 18b and 18c are provided with along in two end opposite of orientation (above-below direction among Fig. 5) each and engage protrusion tab 36 and stop 48.The elastic deformation amount who engages protrusion tab 36 is by stop 48 restrictions.Different is, near joint protrusion tab 36a in the adjacent part between this relay attachment 18b and 18c of relay attachment 18b and 18c and 36a, stop 48 is not set, and engages protrusion tab 36a and 36a toward each other and be spaced apart from each other.If one among joint protrusion tab 36a and the 36a then this engages protrusion tab 36a and will contact another joint protrusion tab 36a along the direction excessive deformation that leaves relay 28, thereby limit excessive distortion.Therefore, in the adjacent part between relay attachment 18b and 18c, an elastic deformation amount who engages protrusion tab 36a can engage protrusion tab 36a restriction by another.Therefore, another stop 48 needn't be set, thereby improve space efficiency and reduce the formation material of main body 12.

Because same relay 28 is installed on adjacent the relay attachment 18b and 18c, so, be arranged on pair of engaging protrusion tab 36a in this adjacent part and the height dimension of 36a and be set to mutually the same.For example, be installed on relay attachment 18b and the 18c respectively and require described joint protrusion tab 36a to have under different elastic deformation amounts' the situation with 36a at the electric component that will have different size, the projecting height that engages protrusion tab 36a and 36a can be set at and differ from one another.

And in the present embodiment, two relay attachment 18b and 18c are disposed adjacent one another with suitable arrangement.Relay attachment 18b and 18c are along being respectively arranged with stop 48 on two opposite ends sides of orientation (above-below direction among Fig. 5).Also can be arranged side by side relay attachment more than three.In this case, the relay attachment in centre between two adjacent relay attachment can not have stop in orientation, and relative joint protrusion tab 36a and 36a can limit the elastic deformation amount mutually.Even a plurality of relay attachment are set, this can prevent that also relay box 10 from maximizing.

Embodiment according to relay box of the present invention has been described above.The foregoing description only is an example of the present invention.The present invention should not be limited to the specific descriptions among the described embodiment.For example, stop can be positioned at any position on the main body, as long as this stop is arranged on the outside that engages protrusion tab.Be provided with in the above-described embodiments under the situation of guiding wall, stop also can be arranged on the guiding wall inboard or the outside and be located along the same line with it.The projecting height of stop can be equal to or greater than the projecting height that engages protrusion tab.

The shape that the concrete shape of joint protrusion tab is not limited to illustrate in the above-described embodiments.For example, engage protrusion tab 36 and can be higher than the upper surface 39 of relay 28, and can have the engaging claw of this upper surface 39 of downward joint.

Guiding wall is always necessary.Stop can be given prominence to independently.Guiding wall can have any structure as required.For example, in the above-described embodiments, can omit side opening 42, relative guiding wall 40 can be coupled to each other along the longitudinal direction of relay attachment 18, and can form the single guiding wall 40 with specific projecting height on whole length along the longitudinal direction.

Although in the above-described embodiments relay box is described as electrical terminal block, electric component can adopt fuse etc.The present invention is applicable to the electrical terminal block such as Fuse box, terminal box etc.
