[0020] As briefly mentioned above, the pluggable electrical device is coupled with the base arranged in the circuit by plugging. At the same time, the plug in the electrical device is inserted into the gap of the claw in the base, thereby realizing the electrical connection between the plug and the claw. In the conventional technology, in order to reduce the damage to the claw caused by the large current when the electrical device is working, the free end of each side of the claw away from the base is formed into multiple forks. In this way, the current flowing through the claw can be diverted.

[0021] However, this diversion method also causes large deviations in the opening sizes between the multiple pairs of forks on both sides of the claw, which is difficult to control in industrial production. This also leads to poor contact between the claw and the plug. The multiple pairs of forks on both sides of the claw are difficult to provide uniform pre-tightening force to the plug. Arcing is easily formed between the claw and the plug under lightning strike, thus causing safety hazards.

[0022] According to the present disclosure, a connection assembly and a device assembly for electrical equipment are provided to solve or at least partially solve the above-mentioned problems and other potential problems existing in the traditional solution. According to an embodiment of the present disclosure, the claw of the connection assembly is coupled to the base through a fixed portion and the bending portions on both sides extend in a direction away from the base, and a pair of bending portions extend to the contact portion in a gradually approaching manner and gradually extend to the free end in a gradually moving away manner. In this way, when the electrical equipment is coupled to the base, the plug of the electrical equipment can be inserted between the pair of bending portions, and contact and electrically connect with the contact portion of the bending portion, so that the claw can maintain stable contact with the plug. At the same time, the processing difficulty of the claw is also reduced. In addition, at least one shunt gap on the bending portion extends at least to the contact portion along the extension direction of the bending portion, thereby shunting the current on the claw, thereby improving the safety of the connection between the claw and the plug.

[0023] Figure 1shows a schematic diagram of the internal structure of a connection component according to some embodiments of the present disclosure, Figure 2 Schematic diagram of the connection between the insert and the insert claw according to some embodiments of the present disclosure is shown. Figure 1 and Figure 2 As shown, the connection assembly generally includes a base 1 and a plurality of claws 2 coupled to the base 1. The base 1 is connected to the circuit and is suitable for coupling with the electrical device to supply power or transmit signals to the electrical device while fixing the electrical device. The claws 2 are coupled to the base 1 and are suitable for electrically connecting with the plugs 5 of the electrical device after the electrical device is coupled to the base 1. The claws 2 include a fixing portion 3 and a pair of bent portions 4 arranged on opposite sides of the fixing portion 3. The fixing portion 3 is suitable for electrically connecting with the circuit in the base 1, and then the fixing portion 3 can be electrically connected with the circuit outside the base 1 via the circuit in the base 1.

[0024] The pair of bent portions 4 are arranged to gradually extend to the contact portion 41 in a mutually approaching manner in a direction away from the base 1, and to gradually extend from the contact portion 41 to the free end 42 in a manner away from each other. In this way, during the coupling of the electrical device to the base 1, the contact portions 41 of the pair of bent portions 4 respectively contact the two sides of the plug 5 of the electrical device and provide a pre-tightening force to the plug 5, thereby making the plug 5 stably contact and electrically connected with the claw 2. In this way, the contact portion 41 of the bent portion 4 can provide a stable pre-tightening force to the plug 5, thereby ensuring a good electrical connection between the plug 5 and the claw 2, reducing the abnormal temperature rise and / or arc generation of the claw 2 and the plug 5 due to poor contact, and improving the safety of the electrical device.

[0025] At least one shunt gap 43 is also formed on the bending portion 4 along the extension direction of the bending portion 4. The shunt gap 43 runs through the thickness direction of the bending portion 4 and extends at least to the contact portion 41 along the length direction of the bending portion 4. Therefore, the shunt gap 43 can shunt the current of the bending portion 4, reduce the local accumulation of current in the bending portion 4, and thereby reduce the local temperature rise of the bending portion 4.

[0026] In some embodiments, the bending portion 4 is connected to the fixing portion 3 via a circular arc chamfered structure. Thus, this structure can reduce the internal stress of the material of the claw 2 during molding and reduce the molding difficulty of the claw 2. On the other hand, this structure can also reduce the accumulation of electric charge at the tip of the claw 2.

[0027] In some implementations, the contact portion 41 may also adopt an arc chamfer transition structure. This can facilitate the insertion of the insert 5 between the pair of bent portions 4, and reduce the wear of the insert 5 and the contact portion 41 during the insertion of the insert 5 into the pair of bent portions 4. In addition, the transition of the arc chamfer structure of the contact portion 41 can also increase the contact area with the insert 5, so that the claw 2 and the insert 5 are stably connected.

[0028] In some embodiments, the shunt groove can be arranged to extend along the extension direction of the bend portion 4 and exceed the contact portion 41 to approach the free end 42 of the bend portion 4. This can better shunt the current of the bend portion 4. However, it should be understood that in order to ensure the overall strength of the bend portion 4 and make the bend portion 4 better contact with the insert 5, there should be at least a predetermined width between the shunt groove and the free end 42 (that is, the shunt groove cannot extend to the free end 42).

[0029] In some embodiments, the claw 2 is integrally formed, for example, the claw 2 can be obtained by bending a profile, and in some embodiments, the diverter groove of the bent portion 4 can also be formed by stamping or wire cutting. However, it should be understood that the above processing method is only exemplary and is not intended to limit the scope of protection of the present disclosure. In fact, the claw 2 and the diverter groove can be processed and formed by any appropriate processing method.

[0030] In some embodiments, the connection assembly further includes a limiting mechanism 6, which is suitable for cooperating with the electrical device after the electrical device is coupled to the base 1, and fixing the electrical device in the base 1. The limiting mechanism 6 includes a limiting member 61 movably coupled to the base 1 and an elastic member arranged between the base 1 and the limiting member 61, the elastic member is suitable for being compressed and driving the limiting member 61 to move (displace or rotate) through elastic force, and the limiting member 61 is suitable for being driven to contact the clamping block 7 of the coupled electrical device, and the electrical device is restricted on the base 1 through the interaction between the limiting member 61 and the clamping block 7.

[0031] In some embodiments, the limit member 61 can be a limit pin, and a mounting hole for accommodating the limit pin is opened on the corresponding base 1. The limit pin is at least partially inserted in the mounting hole and partially extends out of the mounting hole under the drive of the elastic member. The part of the limit pin extending out of the mounting hole contacts and engages with the clamping block 7 of the electrical equipment, so that the limit pin can limit the separation of the electrical equipment from the base 1.

[0032] In some embodiments, the block 7 of the electrical device may also be replaced by a fixing slot. For example, the portion of the stop pin protruding from the mounting hole may be inserted into the fixing slot and fix the electrical device by interacting with the inner wall of the fixing slot.

[0033] In some embodiments, the elastic member may be a spring (eg, a compression spring or a tension spring), or may be a spring sheet or other elastic material, which is not limited in the present disclosure.

[0034] The above descriptions of various implementations of the present disclosure are exemplary, non-exhaustive, and not limited to the disclosed implementations. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described implementations. The selection of terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the various implementations disclosed herein.
