In view of the above, embodiments of the present utility model provide an accessory holder capable of reducing damage to wires of accessories from a top base, an accessory holder, and a top cover.

In a first aspect, an embodiment of the present utility model provides an accessory mount. The accessory seat is applied to a circuit breaker, and the circuit breaker comprises a base and a top cover which are covered with each other. The accessory seat is arranged between the base and the top cover, the bottom of the accessory seat is attached to the base, and the top of the accessory seat is attached to the top cover. The outer wall of the accessory seat is provided with an outlet groove which is communicated with the inside and the outside of the accessory seat, and a lead of the accessory arranged in the accessory seat extends out of the outlet groove to the outside of the accessory seat.

In view of the technical problem that in the prior art, when wires of the accessory extend out of the accessory seat from between the accessory seat and the base or from between the accessory seat and the top cover, the wires are easily damaged by the base and the accessory seat or damaged by the top cover and the accessory seat. In the embodiment of the utility model, the wire outlet groove which is arranged on the outer wall of the accessory seat and is used for communicating the interior of the accessory seat with the exterior of the accessory seat is arranged, so that the wires of the accessory arranged in the accessory seat can extend out of the accessory seat from the wire outlet groove arranged on the accessory seat, and the wires of the accessory are not required to extend out of the accessory seat from the position between the accessory seat and the base or from the position between the accessory seat and the top cover, thereby being convenient for reducing the damage of the base, the accessory seat and the top cover to the wires of the accessory.

In some alternatives, the outer wall of the accessory holder includes a sidewall, the sidewall being located between a bottom of the accessory holder and a top of the accessory holder, and the outlet slot being located in the sidewall.

By means of the scheme, the lead wires of the accessory can extend out of the accessory seat from the accessory seat between the base and the top cover instead of extending out of the accessory seat between the accessory seat and the base or between the accessory seat and the top cover, so that damage to the lead wires of the accessory caused by the base, the accessory seat and the top cover is reduced.

In some alternatives, the outlet slot is located at an edge portion of the sidewall.

Based on the above, the embodiment of the utility model provides an accessory seat applied to a circuit breaker, and by means of a wire outlet groove which is arranged on the outer wall of the accessory seat and is used for communicating the interior of the accessory seat with the exterior of the accessory seat, wires of accessories arranged in the interior of the accessory seat can extend out of the exterior of the accessory seat along the wire outlet groove.

In order to make the person skilled in the art better understand the solution of the present utility model, the technical solution of the embodiment of the present utility model will be clearly and completely described below with reference to the accompanying drawings.

Before the description, first, taking the state of the accessory holder 112 shown in fig. 1 and 4 as an example, the bottom and top of the accessory holder 112 are defined, and the setting positions of the base and the top cover are preset. For example, in fig. 1 and 2, the bottom of accessory holder 112 is defined as the lower portion and the top of accessory holder 112 is defined as the upper portion. When the accessory holder 112 is applied to the circuit breaker, the top cover may be disposed above the accessory holder 112, and the base may be disposed below the accessory holder 112. As another example, in fig. 3 and 4, the bottom of accessory holder 112 is defined as the front and the top of accessory holder 112 is defined as the rear. When the accessory holder 112 is applied to the circuit breaker, the top cover may be disposed at the rear of the accessory holder 112, and the base may be disposed at the front of the accessory holder 112.

Fig. 1 is a first schematic view of an accessory holder 112 according to some embodiments of the present utility model. Fig. 2 is a second schematic view of an accessory holder 112 according to some embodiments of the present utility model. Fig. 3 is a third schematic view of an accessory holder 112 according to some embodiments of the present utility model. Fig. 4 is a fourth schematic view of an accessory holder 112 according to some embodiments of the present utility model. Referring to fig. 1 to 4, the outer wall of the accessory holder 112 is provided with a wire outlet slot C for communicating the interior of the accessory holder 112 with the exterior of the accessory holder 112, and wires of accessories mounted in the interior of the accessory holder 112 extend from the wire outlet slot C to the exterior of the accessory holder 112.

The accessory holder 112 has a receiving chamber therein, and the accessory is received in the receiving chamber. The cavity opening of the accommodating cavity may face the top cover, so that after the accessory enters the accommodating cavity from the cavity opening of the accommodating cavity, the accessory seat 112 can space the accessory from the main circuit installed in the base, and interaction between the main circuit and the accessory is reduced. Furthermore, the accommodation chamber may be provided with one or more based on the number of accessories. For example, in the case where a plurality of accessories are provided, the accommodating chambers may be provided in the same number as the number of accessories, and one accessory may be provided in each accommodating chamber. The accessory may be the internal accessory described previously.

The outer wall of the accessory holder 112 refers to a wall that separates the interior of the accessory holder 112 from the exterior of the accessory holder 112, excluding a wall that separates adjacent two receiving cavities provided within the interior of the accessory holder 112.

The wire outlet groove C is a passage that communicates the inside of the accessory holder 112 with the outside of the accessory holder 112. After the wire outlet groove C communicates the inside of the accessory holder 112 with the outside of the accessory holder 112, the wires of the accessory mounted inside the accessory holder 112 can be extended from the wire outlet groove C to the outside of the accessory holder 112.

In the embodiment of the present utility model, in the case that the outer wall of the accessory holder 112 is provided with the wire outlet groove C that facilitates the extension of the wire of the accessory, the wire of the accessory can extend from the accessory holder 112 itself to the outside of the accessory holder 112 without extending from between the base and the accessory holder 112 or from between the top cover and the accessory holder 112. In this way, the wires of the accessory are not damaged by being held by the base and accessory holder 112 or by the top cover and accessory holder 112.

Specifically, one or more wire outlet slots C may be provided in the outer wall of the accessory holder 112. For example, in the case where one accommodation chamber is provided, one outlet groove C may be provided. In this way, the wires of one or more accessories accommodated in the one accommodation chamber can be protruded from the one outlet slot C to the outside of the accessory holder 112. For another example, in the case where a plurality of accommodating chambers are provided, the number of the wire outlet grooves C may be the same as the number of the accommodating chambers, and one wire outlet groove C may be provided at the outer wall of the accessory holder 112 corresponding to each accommodating chamber. In this way, the wires of the accessories in the plurality of receiving cavities can respectively extend from the corresponding outlet slots C to the outside of the accessory holder 112. The embodiment of the utility model does not limit the number of the wire outlet grooves C.

Further, one or more wire outlet grooves C may be provided in various shapes. For example, one or more wire outlet grooves C may be provided as a circular groove, a polygonal groove, a special-shaped groove, or the like; alternatively, in the case where the wire outlet grooves C are provided in plurality, the first part of the wire outlet grooves C may be provided in a circular shape, the second part of the wire outlet grooves C may be provided in a polygonal shape, the third part of the wire outlet grooves C may be provided in a special-shaped groove, and the like. The shape of the wire outlet groove C is not particularly limited in the embodiment of the utility model.

With continued reference to fig. 1-4, the outlet channel C may be located at various positions on the outer wall of the accessory holder 112. For ease of understanding, the following exemplary description will be given taking the accessory holder 112 as an example of being provided in a substantially rectangular parallelepiped.

In a specific embodiment, as shown in fig. 1 and 2, the outer wall of the accessory holder 112 includes a sidewall A1, the sidewall A1 is located between the bottom of the accessory holder 112 and the top of the accessory holder 112, and the outlet slot C is located at the sidewall A1.

Illustratively, sidewall A1 may be one or more of four sub-sidewalls of the generally rectangular parallelepiped-shaped accessory mount 112. The wire outlet slots C may be located on one or more of the sub-sidewalls.

In this embodiment, since the sidewall A1 is located between the bottom of the accessory holder 112 and the top of the accessory holder 112, the outlet slot C is also located between the bottom of the accessory holder 112 and the top of the accessory holder 112, and the wire of the accessory is also located between the bottom of the accessory holder 112 and the top of the accessory holder 112, instead of being located between the accessory holder 112 and the base or between the accessory holder 112 and the top cover. In this way, the accessory holder 112 and the base or the accessory holder 112 and the top cover do not clamp the wires of the accessory, so that damage to the wires of the accessory by the base, the accessory holder 112 and the top cover is reduced.

Specifically, in some examples, please continue to refer to fig. 1, the outlet slot C is located at an edge portion of the sidewall A1.

The edge portion of the side wall A1 may be an edge portion near the base, an edge portion near the top cover, or two edge portions in a direction perpendicular to the direction in which the base and the top cover are covered (i.e., the left-right direction in fig. 1).

In this embodiment, in the case that the outlet slot C is located at the edge portion of the side wall A1 near the side of the base, although the wire of the accessory may extend from the side wall A1 closer to the base, the wire of the accessory is still located on the accessory holder 112, rather than being clamped between the base and the accessory holder 112, and the wire of the accessory is not easily damaged by the base and the accessory holder 112. Similarly, when the outlet groove C is located at the edge portion of the side wall A1 near the top cover, the wires of the accessory are not clamped between the top cover and the accessory holder 112, and the wires of the accessory are not easily damaged by the top cover and the accessory holder 112.

In addition, in the case where the edge portions of the side wall A1 are two edge portions in the direction perpendicular to the direction in which the base 111 and the top cover are covered (the left-right direction in fig. 1), the wire of the accessory is difficult to clamp between the base and the accessory holder 112 or between the top cover and the accessory holder 112 because of a certain distance between the position where the wire of the accessory extends from the side wall A1 and the base or the top cover, so that damage to the wire of the accessory by the base, the accessory holder 112, and the top cover is reduced.

Specifically, in other examples, please continue to refer to fig. 2, the outlet slot C is located at the middle portion of the sidewall A1.

The middle portion of the sidewall A1 is a region surrounded by the edge portion of the sidewall A1.

In this embodiment, since the distance between the middle portion of the side wall A1 of the accessory holder 112 and the base or the top cover is larger, the distance between the position where the wires of the accessory extend from the accessory holder 112 and the base or the top cover is also larger, and the wires of the accessory are less likely to be clamped between the base and the accessory holder 112 or between the top cover and the accessory holder 112, which is more beneficial to reducing the damage of the base, the accessory holder 112 and the top cover to the wires of the accessory.

In another specific embodiment, referring to fig. 3 and 4, the outer wall of the accessory holder 112 includes a bottom wall A2, and the bottom wall A2 is located at the bottom of the accessory holder 112; the wire outlet groove C is positioned on the bottom wall A2.

In this embodiment, although the bottom wall A2 of the accessory holder 112 is attached to the base, the outlet slot C may be used as a receiving slot to receive the wires of the accessory during the process that the wires of the accessory extend out of the accessory holder 112. When the wires of the accessory can be accommodated by the accommodation groove, the wires of the accessory are not clamped between the base and the accessory holder 112 and are damaged.

Specifically, in some examples, please continue to refer to fig. 3, the outlet slot C is located at an edge portion of the bottom wall A2.

The edge portion of the bottom wall A2 is a portion near the side wall A1 of the accessory holder 112.

The inlet end of the wire outlet groove C may be located at the edge portion of the bottom wall A2 of the accessory holder 112, and the outlet end of the wire outlet groove C may be located at the side wall A1 of the accessory holder 112.

In this embodiment, when the wires of the accessory pass through the outlet slot C, the portion between the inlet end and the outlet end of the outlet slot C can function as a wire for accommodating the accessory, so that the wires of the accessory are not clamped between the base and the accessory holder 112. In addition, the part of the wire of the accessory extending out of the outlet end of the wire slot C is not clamped between the base and the accessory seat 112, so that the base and the accessory seat 112 do not damage the wire of the accessory.

Specifically, in other examples, referring to fig. 4, the outlet groove C extends from the middle portion of the bottom wall A2 to the edge portion of the bottom wall A2.

The inlet end of the outlet slot C may be located at the middle portion of the bottom wall A2 of the accessory holder 112, unlike the outlet slot C located at the edge portion of the bottom wall A2.

In this embodiment, the function of the outlet slot C is the same as that of the outlet slot C when it is located at the edge portion of the bottom wall A2, and will not be described here again.

With continued reference to fig. 1 and 3, in the case where the outlet groove C is located at the edge portion of the side wall A1 or at the edge portion of the bottom wall A2, the outlet groove C is configured as a notch, and the opening dimension L1 of the notch and the in-opening dimension L2 of the notch are configured to satisfy: l1 is less than L2.

In the case where the wire outlet groove C is located at the edge portion of the side wall A1, for example, as shown in fig. 1, if the wire outlet groove C is located at a side close to the top cover, the wire of the accessory may be bent to reach between the accessory holder 112 and the top cover due to a short distance between the wire of the accessory and the top cover, and be clamped by the accessory holder 112 and the top cover to be damaged.

Similarly, if the outlet slot C is located on the side of the sidewall A1 near the base, the wires of the accessory may be damaged by being clamped by the accessory holder 112 and the base.

In the case where the outlet groove C is located at the edge portion of the bottom wall A2, for example, as shown in fig. 3, the wires of the accessory may be damaged by being clamped by the accessory holder 112 and the base.

Based on this, in the present embodiment, by setting the wire outlet groove C as a notch and setting the opening dimension L1 of the notch to be smaller than the in-mouth dimension L2 of the notch, the opening wall of the opening portion can restrict the wires of the accessory to reduce the possibility that the wires of the accessory protrude out of the notch and are clamped between the base and the accessory holder 112 or between the top cover and the accessory holder 112.

Specifically, for example, in the case where the notch is provided at the edge portion of the side wall A1, if the notch is provided at a side close to the top cover with the opening of the notch facing the top cover, the opening size and the intraoral size refer to the sizes in the direction perpendicular to the opening direction and parallel to the plane in which the notch lies (i.e., the approximately right-left direction in fig. 1).

For another example, in the case where the recess is provided at the edge portion of the bottom wall A2, if the opening of the recess is oriented toward the base, the opening size and the intraoral size at this time refer to the sizes in the direction perpendicular to the opening direction and parallel to the plane in which the recess lies (i.e., the approximately right-left direction in fig. 3).

In some embodiments, FIG. 5 is an enlarged view of portion O of FIG. 1 in some embodiments of the utility model. Referring to fig. 5, the outer wall of the accessory holder 112 includes an inner surface A3 and an outer surface A4, the inner surface A3 faces the inside of the accessory holder 112, and the outer surface A4 faces the outside of the accessory holder 112; a first arc-shaped transition surface M1 is arranged between the groove wall of the wire outlet groove C and the inner surface A3; and/or a second arc-shaped transition surface M2 is arranged between the groove wall of the outlet groove C and the outer surface A4.

If the groove wall of the wire outlet groove C is in transition with the inner surface A3 through the edge angle in the process that the wires of the accessories extend into the wire outlet groove C, the edge angle can be in contact with the wires of the accessories to cut the wires of the accessories.
