Abstract
The utility model relates to an electronic type overload relay convenient for fixing a guide rod. The electronic type overload relay comprises an electronic type overload relay substrate, a guide rod preventing a ship type support from pulling away from a mechanism, and an opening groove used for fixing two ends of the guide rod on the substrate; the opening groove consists of an opening part in the shape of a horn mouth, and a round groove part connected with one end of a small mouth in the opening part of the horn mouth and used for holding the tip of the guide rod; and in the opening groove, the diameter at one end of the small mouth of the horn mouth where the round groove is partially communicated with the horn mouth groove is slightly less than the outer diameter of the guide rod. As the opening groove of the guide rod arranged on the substrate is opened in the shape of the horn mouth, the guide rod is squeezed into and clamped in the round groove from one end of the small mouth of the horn mouth-shaped groove by utilizing the elasticity of a plastic piece after the guide rod enters from a big mouth. The overload relay can conveniently fix the guide rod and can easily squeeze out two ends of the guide rod from the small mouth of the horn mouth groove when the guide rod needs to be disassembled, thus reducing the cost of maintenance.
Description
Technical field
The utility model belongs to a kind of electric switch, particularly relates to a kind of electronic overload relay of being convenient to location guide.
Background technology
In present known TR40 electronic overload relay pedestal as the guide rod that prevents to deviate from during ship type support is by mechanism, when it is installed, the bottom that is used for fixing the open recess of guide rod on the relay pedestal is inserted at the two ends of guide rod, after this also needed with sticker guide rod two ends and the adhesion of pedestal opening groove are fixing.Too slow as what do so on the one hand with the sticking back of silica gel sticker; With 101 gluing after, guide rod is not easy again to pull down when mechanism need reprocess, and in case pull down guide rod and be easy to distortion and can't continue to use, thereby has also increased maintenance cost.
Summary of the invention
The utility model provides a kind of electronic overload relay that can be convenient to dismantle and be convenient to location guide for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it includes the electronic overload relay pedestal, prevents that ship type support is used for fixing described guide rod openings at two ends groove by the guide rod of deviating from the mechanism and on described pedestal, described open recess be by the opening portion that becomes the toroidal groove and therewith osculum one end of iiared port part join, be used to contain and receive the circular groove of described guide rod termination and partly form; In described open recess, the diameter of horn mouth osculum one end that described circular groove is connected with the horn mouth groove is slightly less than the external diameter of described guide rod.
The utility model can also adopt following technical scheme:
The diameter of horn mouth osculum one end that described circular groove is connected with the horn mouth groove part is less than the external diameter 0.25-0.4 millimeter of described guide rod.
Advantage and the good effect that the utlity model has are: by pedestal being installed the oblong open recess of guide rod, changing opening into is that toroidal has descending closing in shape, iiared port is convenient to guide rod and mouthful is entered by big like this, utilize the elasticity of plastic that guide rod is clamp-oned by osculum one end of toroidal groove afterwards again, and it is stuck in the circular groove.From then on can simply and easily guide rod be fixed, and when needs are pulled down guide rod, difficulty the osculum place by the horn mouth groove, the two ends of guide rod is extruded not really again, from and cost can reduce maintenance the time.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B portion enlarged drawing among Fig. 2.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
As shown in Figure 1, 2, 3, guide rod 2 is housed in pedestal 1, is fixedly having open recess 4, open recess 4 to constitute with the horn mouth groove 6 that becomes toroidal on the sidewall at cylinder 3 upper fixed guide rods 2 two ends of electron plate on the pedestal 1 by circular groove 5.Osculum one end of horn mouth groove 6 is connected with circular groove 5.The diameter of horn mouth osculum one end that circular groove 5 is connected with horn mouth groove 6 is less than 0.3 millimeter of the external diameter of guide rod 2.The diameter of horn mouth osculum one end that also can be horn mouth groove 6 is less than 0.4 millimeter of the external diameter of guide rod 2.Guide rod 2 is fixed by extruded entering in the circular groove 5 through osculum one end of horn mouth groove 6.
Claims (2)
1. electronic overload relay of being convenient to location guide, it includes the electronic overload relay pedestal, prevents that ship type support is used for fixing described guide rod openings at two ends groove by the guide rod of deviating from the mechanism and on described pedestal, it is characterized in that: described open recess be by the opening portion that becomes the toroidal groove and therewith osculum one end of iiared port part join, be used to contain and receive the circular groove of described guide rod termination and partly form; In described open recess, the diameter of horn mouth osculum one end that described circular groove is connected with the horn mouth groove is slightly less than the external diameter of described guide rod.
