For overcoming the above-mentioned problems in the prior art, the utility model discloses a kind of printed board plug-in unit spanner, the plug of printed board plug-in unit can be assisted to operate.
The utility model have employed following technical scheme:
A kind of printed board plug-in unit spanner, comprises spanner 1 and mounting blocks assembly 2; It is characterized in that:
Described spanner 1 is nested with the boss E on mounting blocks assembly 2 coordinates by installing hole F and rotates around boss E;
The side of described spanner 1 is provided with front hook C and rear hook D.
The utility model is further preferred following technical scheme also:
Mounting blocks assembly 2 is made up of mounting blocks 3, collision bead 4, spring 5, plug 6, and wherein, collision bead 4 and spring 5 are placed in the circular hole of mounting blocks 3 end successively, and by plug 6 shutoff outside described circular hole, close up in inner side.
Described spanner 1 is provided with two circular holes A, B coordinating with collision bead 4 in rotation process and locate.
The operating side of spanner 1 is provided with silica gel sheath.
Described spanner 1 has two location holes, spanner 1 turns an angle, and collision bead 4 can be made to slip in location hole under the effect of spring 5, position spanner.
Mounting blocks assembly 2 of the present utility model can also only mounting blocks 3 and torsion spring 11 form, and wherein, torsion spring 11 is arranged in the end recesses H of mounting blocks 3.
The utility model has following useful technique effect:
Novel printed board plug-in unit spanner disclosed in the present application can realize helping of printed board plug-in unit and insert and help and pull out function, and the mechanism of its particular design can position spanner.It has structure simple, easy to use, help the plug advantages such as reinforcement is large.

Embodiment
Be described in further detail below in conjunction with the technical scheme of Figure of description to the application.
Be illustrated in figure 1 the outside drawing of plug-in unit spanner, form primarily of spanner 1 and mounting blocks assembly 2, as shown in Figure 2.Spanner 1 there is silica gel sheath, the feel of operation can be increased.Mounting blocks assembly is made up of mounting blocks 3, collision bead 4, spring 5, plug 6, as shown in Figure 3.There is a circular hole end of mounting blocks 3, and close up in the end of circular hole inboard, collision bead can be made to stretch out end face certain distance and be unlikely and leave circular hole, collision bead 4 and spring 5 are positioned in circular hole respectively, and outside plug is fixed.Spanner 1 there are two location hole A and B, as shown in Figure 2, when plug-in unit spanner rotates, collision bead 4 can be made under the effect of spring 5 to slip into location hole A and B respectively, thus make spanner 1 have two positioning states, if Fig. 4-1 is with shown in Fig. 4-2.
The installation of plug-in unit spanner does not need other fixtures.Fig. 5 indicates the installation process between spanner 1 and mounting blocks assembly 2.First be positioned on the boss E of mounting blocks assembly 2 by the position of the left figure of Fig. 5 by the installing hole of spanner 1, then rotate about 180 °, namely spanner 1 completes the connection between mounting blocks assembly 2.
Fig. 6 is the scheme of installation of printed board plug-in unit in subrack, and sequence number 7 is the panel of printed board plug-in unit, and sequence number 8 is printed board, and need 9 to be guide-rail plates, sequence number 10 is printed board backboards.Fig. 7 indicates the effect of plug-in unit spanner 1 in the insertion process of printed board plug-in unit.When printed board plug-in unit inserts subrack, by rotating spanner 1, the front hook C of spanner 1 is contacted with the square hole F edge on guide-rail plate, and produces the active force of printed board direction of insertion, thus realize helping slotting action.Fig. 8 indicates the effect of plug-in unit spanner in the withdrawal process of printed board plug-in unit.By counter-rotation spanner 1, the rear hook D of spanner 1 is contacted with the flanging G on guide-rail plate, and produces the active force that direction is extracted in printed board, thus realize helping stirring work.Because spanner has leverage, make the power acting on spanner much smaller than the contact engaging and separating force of contact pin, facilitate the plug operation of printed board plug-in unit.
Fig. 9 is a kind of alternative structure of mounting blocks assembly: it comprises mounting blocks 3 and torsion spring 11, and there is the groove H matched with torsion spring 11 side of mounting blocks 3, is substituted the effect of spring 5 in said structure and collision bead 4 by the twisting resistance of torsion spring 11.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, although be described in detail the utility model with reference to accompanying drawing with reference to above-described embodiment, those of ordinary skill in the field are to be understood that, still can modify to embodiment of the present utility model or equivalent replacement, and do not depart from any amendment of the utility model spirit and scope or equivalent replacement, all should be encompassed in the middle of right of the present utility model.
