Background

Along with the rapid development of cities, high-rise buildings are more and more, the electricity load of the buildings is increased rapidly, and the conventional electric wires and cables are gradually replaced by bus ducts with large capacity, convenient branching and convenient bundling management due to the reasons of small capacity, inconvenient branching, inconvenient bundling management and the like. The bus duct is widely applied to important projects such as hotels, airports, subways and the like, so that the safety and stability performance of related products of the bus duct is very important.

SUMMERY OF THE UTILITY MODEL

There are several areas in which improvements are needed in conventional plug members adapted to be inserted into a bus duct. For example, conventional plug members are generally complex in structure, not conducive to plugging and unplugging, and not conducive to reducing manufacturing costs. For example, conventional plug components typically have contacts on only a single side, and thus only single-sided electrical connections can be made. As another example, conventional plug members are typically less resilient to be retained and positioned in the busbars of a busway by an interference fit achieved by elastic deformation of the plug members themselves, and so on. The present invention provides an improved plug part to address or at least partially address the above or other potential problems.

In one aspect, embodiments of the present disclosure provide a docking component.

The insertion portion includes: at least two segments separated by a slot extending along the longitudinal axis and wherein at least one segment of each of adjacent segments is oppositely curved in a direction perpendicular to the plane of the main body portion to form a curved segment adapted to elastically deform during insertion into the busbar; and a plurality of contacts, each of which is formed on one of the at least two sections and adapted to abut against an inner surface of the busbar in a state where the insertion portion is inserted into the busbar, so that the plug member is electrically connected with the busbar.

In some embodiments, the section comprises a planar section distal to the main body portion, the planar section is coplanar with a plane in which the main body portion lies, and the curved section is disposed between the main body portion and the planar section.

In some embodiments, the contact is convex in the direction to maximize a contact area of the insertion portion with an inner surface of the busbar.

In some embodiments, the contacts in the adjacent segments have an initial distance in the direction before being inserted into the female row and the cavity has a width in the direction, wherein the initial distance is greater than the width.

In some embodiments, the contact is formed at a maximum distance of the curved section from a plane in which the body portion lies.

In some embodiments, the curved section comprises: a pair of deformation sections adjoining the main body section and the planar section, respectively; a contact section disposed between the pair of deformation sections and disposed substantially parallel to a plane in which the main body portion is located; and wherein the contacts are arranged on the contact segments.

In the context of the present disclosure, the term "comprising" and its various variants can be understood as open-ended terms, which mean "including but not limited to"; the term "based on" may be understood as "based at least in part on"; the term "some embodiments" may be understood as "at least some embodiments"; the term "another embodiment" may be understood as "at least one other embodiment".

According to some embodiments of the present disclosure, an improved plug member is provided. Generally, the plug part (which may also be referred to as "plug claw" or "plug claw") according to the embodiment of the present disclosure has the advantages of simple structure, easy plugging and unplugging, good electrical contact with the busbar of the bus duct, low heat generation, and the like.

A socket part according to an exemplary embodiment of the present disclosure will be described below with reference to fig. 1 to 4.

Fig. 1 illustrates a docking component 100 according to an embodiment of the present disclosure. The socket member 100 includes a body portion 150 and an insertion portion 160. The length of the insertion member 100 is defined by the length of the body part 150 and the length of the insertion part 160. The length of the plug member 100 extends along a longitudinal axis L shown in the figures.

The body portion 150 is in the form of a flat sheet or plate, thereby defining a plane in which it lies. The insert 160 comprises two sections on either side of the longitudinal axis L, which are separated by a slot 130. The slot 130 is formed along the longitudinal axis L. The specific manner of forming the slot 130 includes any manner that is currently or may be implemented in the future and is not necessarily limited thereto.

As shown in fig. 1, each section of the insert 160 on either side of the longitudinal axis L may include a generally curvedly shaped curved section. In some embodiments, the curved section may be formed by, for example, stamping. However, other existing and future implementations may be used to form the curved section.

In some embodiments, at least one segment of each segment separated by the slot 130 is oppositely curved in a direction Z perpendicular to the plane of the main body portion 150, respectively, thereby resulting in the curved segment. This curved configuration is particularly suitable for the insert 160 to elastically deform during insertion into the busbar 500 (fig. 4) of the bus duct.

In addition, a contact is arranged on each section of the insertion portion 160. As shown in the figure, one section is provided with contacts 111 and the other section, bent oppositely in the direction Z, is provided with contacts 121.

In some embodiments, the number of contacts on each segment need not be one as shown, and more than one contact may be provided depending on the actual length of the segment.

In some embodiments, since the bending directions of the two sections of the insertion portion 160 are opposite, the contact 111 and the contact 121 are correspondingly oppositely convex in the direction Z. In other words, the surface of contact 111 contacting busbar 500 and the surface of contact 121 contacting busbar 500 are opposite to each other. In this way, when the insert 160 is inserted into the busbar 500, the

contacts

111 and 121 each contact the inner surface 501 of the busbar 500, thereby electrically connecting the plug member 100 with the bus duct.

In some embodiments, each section further comprises a planar section (or flattened end) distal to the body portion 150, as shown in fig. 1. The

planar segments

112, 122 are shown. The

planar sections

112, 122 are coplanar with the plane of the main body 150, and the curved section of each section is disposed between the main body 150 and the corresponding

planar section

112 or 122. The arrangement of the

planar sections

112, 122 facilitates entry of the insert 160 into a narrow space or gap, such as the cavity 510 of the busbar 500 shown in fig. 4.

In some embodiments, the

contacts

111, 121 are oppositely convex in direction Z, i.e. the

contacts

111, 121 each are convex towards the inner surface 501 of the busbar 500 in the inserted state of the busbar 500. This maximizes the contact area of the insertion portion 160 with the inner surface 501 of the busbar 500, thereby improving contact resistance and reducing heat generation.

In some embodiments, the curved section of each section of the insert 160 may include a pair of deformation sections and a contact section between the deformation sections. Referring to fig. 1, the curved section of one segment comprises two

deformed sections

110, 1101, and a contact section between the two deformed sections on which contacts 111 are arranged. The curved section of the other segment comprises two

deformation sections

120, 1201 and a contact section between the two deformation sections on which a contact 121 is arranged.

For each segment, one of its two deformations is adjacent to the body portion 150, and the other deformation abuts the planar segment. In some embodiments, the

deformation segments

110, 1101, 102, 1201 may for example be rounded segments, i.e. shaped as smooth segments. This design can provide a good guide for the insertion portion 160, and facilitate the smooth sliding of the plugging member 100 to a designated position in the busbar 500.

In some embodiments, the contact segments may be arranged substantially parallel to the plane of the body portion 150. Such a design may, for example, provide for a more snug fit of the contacts with the inner surface of the busbar, thereby providing for a more reliable electrical connection of the plug member 100 to the bus duct.

In the embodiment shown in fig. 1, the insertion portion 160 of the plug member 100 is divided into two left and right portions having central symmetry by the slot 130. The centrosymmetric structure is combined with a means of manufacturing the plugging component by using an elastic material, so that the plugging component has certain self-adaptive capacity and self-positioning capacity, and further, the good assembly effect of the plugging component in the busbar is ensured.

The difference between the plug part 200 shown in fig. 2 and the plug part 100 shown in fig. 1 is mainly focused on the design of the plug part. Therefore, in the description of fig. 2, the same or similar parts as those of the embodiment shown in fig. 1 may be omitted.

As shown in fig. 2, the insertion portion 260 of the plug part 200 comprises three sections separated by two grooves, i.e. two sections bent downwards on either side of the longitudinal axis L and an intermediate section bent upwards in between.

Similar to the embodiment shown in fig. 1, the three sections of the insertion portion 260 in fig. 2 are provided with

contacts

211, 221, 231, respectively. Reference may be made to the description of the embodiment of fig. 1 with respect to the arrangement of the contacts (e.g., the direction of the bumps, etc.).

Likewise, each of the three sections of the insertion portion 260 of the plug part 200 may comprise a curved section. Each curved section may include a pair of deformed sections and a contact section between the deformed sections.

For example, one section bent down in fig. 2 comprises a bent section and a planar section, wherein the bent section in turn comprises a

deformed section

210, 2101 and a contact section between the two deformed sections on which the contacts 211 are arranged. The other section, bent downwards in fig. 2, comprises a curved section and a planar section, wherein the curved section in turn comprises a

deformation section

230, 2301, and a contact section between the two deformation sections, on which the contact 231 is arranged.

In some embodiments, for example in examples where there are more than two sections of the insert, different sections may have different dimensions. For example, in the insert 260 shown in fig. 2, the size of the middle upwardly curved section may be larger than the size of the two downwardly curved sections. Such changes may be those made to a particular application environment.

In other embodiments, the number of sections of the insert may be any number greater than 2, and all sections may have the same dimensions. The design facilitates the manufacturing and processing of the plug-in component, and can advantageously shorten the manufacturing time and reduce the manufacturing cost.

Plug member 300 shown in fig. 3 may be a side view of plug member 100 shown in fig. 1 or a side view of plug member 200 shown in fig. 2. In other words, how many sections the insertion portion of the plug part is divided into, each of which assumes the configuration shown in fig. 3 when viewed from the perspective shown in fig. 3.

The plug part 400 of the embodiment shown in fig. 4 may represent the plug part 100 of fig. 1, the plug part 200 of fig. 2 or the plug part 300 of fig. 3. As schematically shown, the plug member 400 is being inserted into the cavity 510 of the busbar 500 in the direction H (i.e. the direction of the longitudinal axis L).

Before being inserted into the busbar 500, the

contacts

401, 402 on adjacent sections of the insert have an initial distance D1 in direction Z, and the cavity 510 of the busbar 500 has a width D2 in direction Z, wherein the initial distance D1 is greater than the width D2. In some embodiments, the

contacts

401, 402 are formed at locations where the curved section of the insert 400 is at a maximum distance from the plane of the body portion 450. In one example, where the cavity 510, e.g., busbar 500, has a width D2 of about 3mm in direction Z, the initial distance D1 may be about 4.6 mm.

A plugging member according to an embodiment of the present disclosure is adapted for use in a bus duct, in particular with respect to a data center facing bus duct. The plug part may have, for example, a single-layer sheet-like structure and may be of a centrosymmetric structure. Due to the various improvements described above in connection with the exemplary embodiments, the plug-in fitting accuracy of the plug part is less demanding, as a result of which the production and production costs can be advantageously reduced.

In some embodiments, the plug member may be made of a resilient copper material.

In some embodiments, the contact surface of the insertion portion of the plug-in part may be designed with raised structures, such as contacts. This increases the contact area of the insert portion with the busbar, thereby reducing the contact resistance, advantageously enhancing the heat dissipation performance of the insert member.

One of the main features of the plug part according to embodiments of the present disclosure is the elastic deformability of the insertion portion. The elastic contact between the plug-in component and the busbar realized by the elastic deformation can effectively avoid the problem of loose contact caused by expansion with heat and contraction with cold in the long-term operation of the busbar.

In general, the insertion part according to the embodiments of the present disclosure has, but is not limited to, the following advantages under the overall technical concept of the present disclosure:

first, the socket member may be a single-piece, single-layer structure, so that the material used to manufacture the socket member is reduced and the manufacturing process can be simplified. The plug part can be regarded as an integrally formed part, so that no assembly is required.

The second and plug-in parts can be made of elastic copper material. Under the operating condition of the plug-in component, the elastic deformation of the plug-in part enables the contact area of the plug-in component and the busbar to be larger, so that the contact resistance is reduced, and the heat generation is reduced.

Third, the front end (or the insertion portion) of the plug member is grooved to divide it into a plurality of sections, thereby maximizing the contact area of the insertion portion with the busbar in actual contact. In this way, the contact resistance of the plug part is improved, whereby the problem of heat generation of the plug part is alleviated or even eliminated.

Fourth, when viewed from a side view, for example, the plug member is of a symmetrical arcuate configuration with a flat front end and a bowed middle portion, thereby assuming an arcuate transition or curved configuration as a whole. In the process of inserting the plug-in component into the busbar, the flat structure at the front end of the plug-in component can easily enter the cavity of the busbar. In this way, the plug-in part can also be positioned well even when the fitting accuracy is not high, since the arc transition of the insertion part has a good guiding effect on the plug-in part. In this way, it can be ensured that the plug-in part smoothly reaches the designated position along the cavity of the busbar. After being in place, the bent section of the plug part can provide sufficient elastic pressing force to ensure reliable contact of the plug part with the busbar.

And fifthly, each section of the plug-in component is provided with a contact, and the contact of the connected section is opposite to the contact surface of the busbar. This design enables the plug member to make electrical connection with the busbar on both sides, rather than on a single side.

It will be appreciated by those skilled in the art that the above-described embodiments may be modified without departing from the scope and spirit of the disclosure.
