The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. The terms "comprises" and "comprising," along with any variations thereof, in the description and claims, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Referring to fig. 1, 2 and 5 to 10, an embodiment of the present application provides a panel connector 1 for connecting two adjacent panel bodies 21 (as shown in fig. 5) on an outer frame assembly 2, wherein the panel connector 1 includes two connecting arms 11, one ends of the two connecting arms 11 are connected to each other and form an included angle, and the other ends of the two connecting arms 11 are respectively inserted into insertion cavities 211 (as shown in fig. 10) at the ends of the two panel bodies 21. As shown in fig. 2, 7 and 9, at least one outer sidewall of the connecting arm 11 and/or at least one inner sidewall of the plugging cavity 211 are provided with a protruding portion 111.

As shown in fig. 10, when the connecting arm 11 is inserted into the insertion cavity 211, the parts of the protruding part 111 and the contact protruding part 111 are damaged due to friction, so that the connecting arm 11 and the corresponding two guard plate bodies 21 form an equipotential body, and when the connecting arm 11 is inserted into the insertion cavity 211, the protruding part 111 is used for increasing the resistance of relative sliding between the connecting arm 11 and the insertion cavity 211.

The working principle of the guard board connecting piece 1 is that as shown in fig. 10, when two adjacent guard board bodies 21 on the outer frame assembly 2 are required to be spliced and fixed under the action of two connecting arms 11, only one ends, far away from each other, of the two connecting arms 11 are required to be respectively inserted into the inserting cavities 211 at the end parts of the two adjacent guard board bodies 21, and the splicing and fixing between the two adjacent guard board bodies 21 can be realized.

Under the effect of the protruding portion 111, after the connecting arm 11 is inserted into the inserting cavity 211, the protruding portion 111 is used for increasing the resistance of relative sliding generated between the connecting arm 11 and the inserting cavity 211, so that the connecting arm 11 and the inserting cavity 211 are clamped more firmly, and further the stability and the firmness of the interconnection between two adjacent guard plate bodies 21 are improved.

In addition, as the surface of the guard plate body 21 is usually subjected to a treatment process such as baking varnish, spray paint or coloring, etc., the surface of the guard plate body 21 is in an insulating state, but under the action of the protruding portion 111, when the connecting arm 11 is inserted into the inserting cavity 211, the protruding portion 111 and a portion contacting the protruding portion 111 cause damage to a paint surface due to friction, so that the connecting arm 11 and the two corresponding guard plate bodies 21 form an equipotential body, that is, the two adjacent guard plate bodies 21 can be conducted through the guard plate connecting piece 1, so that the whole tile conduction can be realized, and further, the guard plate is convenient to have good use safety when only single-point grounding. Otherwise, if the two adjacent guard plate bodies 21 are not conducted due to insulation of the paint surface, that is, the whole tile conduction cannot be realized, and if single-point grounding is adopted at this time, the situation that the electric leakage position is not conducted with the grounding wire exists, the use safety cannot be completely ensured, and a large potential safety hazard exists.

In some embodiments of the present application, in order to enhance the effect of the protruding portion 111, at least one outer side wall of the connecting arm 11 is provided with the protruding portion 111, and at least one inner side wall of the plugging cavity 211 opposite to the protruding portion 111 on the connecting arm 11 is provided with the protruding portion 111.

It should be understood that the number of the protruding parts 111 on the outer side wall of the connecting arm 11 or the inner side wall of the plugging cavity 211 is not limited in the present application, and any number of protruding parts 111 can be provided according to actual needs, and preferably, the protruding parts 111 are arranged at equal intervals.

The specific structure of the protruding portion 111 is not limited, and only a preferable structure is provided in which the protruding portion 111 is preferably an elongated tooth tip structure as shown in fig. 2, 7 and 9. Wherein, the tooth point structure is convenient for improve the destruction effect to the paint surface, and rectangular form structure is convenient for integrated into one piece.

In order to further improve the effect of the protruding portions 111 on the two contact surfaces of the connecting arm 11 opposite to the socket cavity 211, the length direction of the tooth tip structure on the connecting arm 11 and the length direction of the tooth tip structure in the socket cavity 211 are intersected with each other, that is, by arranging the protruding portions 111 on the two contact surfaces of the connecting arm 11 opposite to the socket cavity 211 to be intersected with each other, during the process of inserting the connecting arm 11 into the socket cavity 211, the protruding portions 111 on the connecting arm 11 and the protruding portions 111 in the socket cavity 211 are contacted with each other and generate abrasion, the contact area between each other is smaller, that is, the destructive power is stronger, that is, the destructive power to the paint surface is stronger, and meanwhile, the biting force between the contact surfaces is larger, so that larger resistance is provided.

Referring to fig. 10, in some embodiments of the present application, for convenience in forming, the length direction of the tooth tip structure in the insertion cavity 211 is parallel to the length direction of the corresponding shield body 21, thereby facilitating the integral forming of the protrusion 111 while forming the shield body 21. The length direction of the tooth point structure on the connecting arm 11 is perpendicular to the length direction of the tooth point structure in the corresponding inserting cavity 211, namely, the length direction of the tooth point structure is along the thickness direction of the connecting arm 11, so that demolding is facilitated during molding, and in addition, compared with the situation that opposite convex parts 111 are obliquely intersected, the area of the mutual contact surface between the convex parts 111 can be further reduced during perpendicular (namely, positive intersection).

As shown in fig. 3 and 4, the splice between two adjacent guard plate bodies 21 is complementary to each other under the action of two adjacent bevel structures 212.

It should be understood that the angle of the inclined surface structure 212 and the angle between the two connecting arms 11 need to be set according to the shape of the outer frame assembly 2, for example, when the outer frame assembly 2 is rectangular, the angle of the inclined surface structure 212 is 45 ° and the angle between the two connecting arms 11 is 90 °.

Referring to fig. 1 and 10, in some embodiments of the present application, the two connecting arms 11 are provided with bevel structures 112 at the ends thereof remote from each other, and the bevel structures 112 facilitate insertion of the connecting arms 11 into the socket cavities 211.
