As shown in fig. 1 and 2, the utility model provides a servo driver end cover, which comprises an end cover body 1, wherein the end cover body 1 is detachably mounted at the end of a servo driver, and a plurality of functional through holes are usually arranged on the end cover body 1 for the functional plugs on the control board on the driver to pass through; in addition, the concave mounting groove 1.1 that forms a rectangle that caves in the up end of end cover body 1 to be equipped with the installation through-hole 1.2 that is used for supplying binding post on the servo driver to wear out in the bottom of mounting groove 1.1, on the one hand again, be equipped with the opening with mounting groove 1.1 intercommunication on the preceding lateral wall of end cover body 1, foretell mounting groove 1.1 front end is the open-ended promptly, the outside wiring can be followed the front end inlet wire of driver after setting up like this, then be perpendicular angle wiring fixed with the binding post that wears out in the installation through-hole 1.2, convenient wiring. In addition, in order to protect the outside of the wiring terminal and improve the safety performance in the embodiment, the upper end of the mounting groove 1.1 is connected with the reversible cover plate 2, namely the cover plate 2 can be assembled on the upper part of the mounting groove 1.1 in a closed mode in an initial state or after wiring is completed, when wiring or disconnection is needed, the cover plate 2 can be opened in an easily-turned mode, the structure is simple, and the operation is very convenient. Specifically, when apron 2 and mounting groove 1.1 lid closed in the above-mentioned structure, the up end of apron 2 and the up end parallel and level of end cover body 1 guarantee the level of 1 surface of end cover body, improve pleasing to the eye degree. In addition, be equipped with spacing portion between end cover body 1 and apron 2 for to apron 2 prescribe a limit to towards the angle that the rear portion of end cover body 1 was opened in the upset, thereby guarantee the stability of apron 2 back position of opening.

In the above structure, as shown in fig. 2 to 4, the specific structure of the stopper part is shown as follows: the position that is located hinge hole 1.3 below on the at least one lateral wall of the mounting groove 1.1 left and right sides is equipped with stopper 4, and the upper end of stopper 4 is equipped with positioning groove 4.1, and when apron 2 opened the upset towards the rear portion and personally submitted vertical angle with the upper end of end cover body 1, the tip that apron 2 is close to articulated shaft 2.1 clamps and limits in positioning groove 4.1 for it continues to overturn backwards to restrict apron 2. In the embodiment, the limiting block 4 is only arranged on the left side of the mounting groove 1.1; in other embodiments, in order to better ensure the stability of the limiting, the limiting blocks 4 can be arranged on the left side and the right side of the mounting groove 1.1.

In this embodiment, the flip structure of the cover plate 2 and the mounting groove 1.1 means: be equipped with hinge hole 1.3 on the lateral wall about mounting groove 1.1 respectively, it is corresponding, be equipped with respectively in the both sides of apron 2 with two hinge hole 1.3 cartridge complex articulated shaft 2.1 to make apron 2 can overturn around articulated shaft 2.1 around. More specifically, as shown in fig. 2 and 3, the hinge hole 1.3 is arranged at the rear end of two side walls of the mounting groove 1.1; correspondingly, articulated shaft 2.1 is protruding to be established on the both sides wall of apron 2 rear end, guarantees apron 2 upset smoothness nature and stability.

On the other hand, because in this embodiment, when the cover plate 2 is closed, it is necessary to ensure that the outer end surface thereof is flush with the outer wall of the end cover body 1, so there is a corresponding limit for the position of the cover plate 2 when closed, specifically, at least one vertically extending support plate 3 is disposed at the bottom of the mounting groove 1.1 near the front end of the end cover body 1, and when the cover plate 2 is closed with the mounting groove 1.1, the lower surface of the front end of the cover plate 2 abuts against the top of the support plate 3, so as to limit the position of the cover plate 2. More specifically, as shown in fig. 1, in this embodiment, two supporting plates 3 disposed at an interval are disposed at the bottom of the mounting groove 1.1 to limit the cover plate 2, so as to ensure the stability of the limiting structure.

In addition, when guaranteeing 2 lids of apron and closing the time high position and injecing, still need consider 2 lids of apron and can not open by oneself after closing, avoid artificially touching binding post, all be equipped with location jack 1.4 in the both sides of the near end cover body 1 front end in the bottom of mounting groove 1.1 in this structure, be equipped with on the apron 2 two with location jack 1.4 respectively cartridge complex location insert post 2.2. Each location is inserted post 2.2 and is kept away from and be equipped with spacing step 2.2.1 on the lateral wall of 2 one ends of apron, and when location was inserted post 2.2 cartridge cooperation and is leaned on in location jack 1.4 until spacing step 2.2.1 and mounting groove 1.1 bottom plate, apron 2 was leaned on with 3 tops offsets of backup pad, guarantees to lap accuracy, stable spacing of 2 positions. Further in this structure, can also set up elastic buffer (not shown in the figure) at the top of each backup pad 3 for when 2 lid of apron closed the motion, before post 2.2 was inserted in the location cooperation to the location jack 1.4 that corresponds, the lower extreme of apron 2 contacted with the elastic buffer at backup pad 3 top earlier, then apron 2 continues to push down the lid and closes, overcome elastic buffer's effort, accomplish the cartridge lock joint at last, under elastic buffer's effect, guarantee the location and insert the slow cooperation of post 2.3 and location jack 1.4, avoid because of the cartridge effort is too big, lead to the location to insert post 2.2 and warp or split.

As shown in fig. 5, still be equipped with the joint portion 2.3 of evagination on the lateral wall of two location inserted columns 2.2, when location inserted column 2.2 cartridge cooperation was in location jack 1.4, the up end of joint portion 2.3 supported with the lower terminal surface of end cover body 1 and leaned on, and when apron 2 front end received ascending effort, the joint portion 2.3 can break away from in location jack 1.4. That is, when the cover plate 2 needs to be opened, the front end of the cover plate 2 is pulled upwards by hands.

Although the present disclosure has been described above, the scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and such changes and modifications will fall within the scope of the present disclosure.
