Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It is to be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present utility model are shown in the drawings. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the utility model. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
Most connectors in the battery pack of an electrical device do not allow for protection of the output stage. While normally the connector is not shorted, there is a possibility of accidents. For example, if the battery pack at the bottom of the new energy vehicle is in a driving process, metal is dropped out due to long-term collision, and the battery pack falls between the positive electrode and the negative electrode of the output stage, so that the connector is short-circuited. I.e. the connector in the unprotected state, the output stage is in a bare state, which easily leads to a risk of short-circuits when falling off. Of course, such problems may also exist with the remaining electrical components.
Based on this, the present utility model designs an injection molding 100 to protect the electrical components by the injection molding 100, so as to avoid the risk of short circuit caused by the exposed electrical components.
As shown in fig. 1, 2 and 3, the injection molding 100 includes a first fixing plate 110 and a second fixing plate 120. The first end of the first fixing plate 110 and the first end of the second fixing plate 120 are flexibly connected such that the first fixing plate 110 and the second fixing plate 120 are folded or unfolded with respect to each other. The second ends of the first and second fixing plates 110 and 120 are provided with fixing structures 130, and are fixedly connected through the fixing structures 130 when the first and second fixing plates 110 and 120 are folded.

The first fixing plate 110 and the second fixing plate 120 can be easily folded or unfolded relatively through the flexible connection between the first fixing plate 110 and the second fixing plate 120, the first fixing plate 110 and the second fixing plate 120 are fixedly connected through the fixing structure 130 at the other end of the first fixing plate 110 and the second fixing plate 120 when the first fixing plate 110 and the second fixing plate 120 are folded relatively, the fixing and the dismounting of the injection molding piece 100 are convenient, and the first accommodating groove 111 on the first fixing plate 110 and the second accommodating groove 121 on the second fixing plate 120 in the injection molding piece 100 are arranged relatively when the first fixing plate 110 and the second fixing plate 120 are folded relatively, so that a large accommodating space is formed by combining the first accommodating groove 111 and the second accommodating groove 121, a connector or other accommodating object can be placed through the accommodating space, the accommodating object can be limited in the first accommodating groove 111 and the second accommodating groove 121, the relative displacement between the accommodating object and the first fixing plate 110 and the second fixing plate 120 can be reduced, and the other accommodating object can be placed on the connector or the other accommodating piece 100 reliably.
Illustratively, as shown in fig. 4, when the accommodating object is a connector, the first accommodating groove 111 and the second accommodating groove 121 are respectively used for accommodating two ends of the connector in an electrical device such as a battery pack.
In an implementation manner, the injection molding piece 100 may be integrally formed of a flexible material, so that one end of the first fixing plate 110 and one end of the second fixing plate 120 in the injection molding piece 100 are flexibly connected, and the connection between the one end of the first fixing plate 110 and the one end of the second fixing plate 120 is not loosened, so as to improve the reliability of the injection molding piece 100.
Optionally, referring to fig. 3, in the case that the injection molding piece 100 is integrally formed, a bending groove may be formed on the first fixing plate 110 and/or the second fixing plate 120, so that the bending is more labor-saving and the bending portion is prevented from protruding outwards, so that the injection molding piece 100 may not fall off naturally, and the injection molding piece 100 may be reliably fixed on the connector or other accommodating objects, so as to improve the reliability of the injection molding piece 100.
Preferably, the bending grooves may include a first bending groove 112 and a second bending groove 122. Specifically, the first end of the first fixing plate 110 connected to the second fixing plate 120 is formed with a first bending groove 112, and the first end of the second fixing plate 120 connected to the first fixing plate 110 is formed with a second bending groove 122, so that the bending part is further prevented from protruding outwards by providing the first bending groove 112 and the second bending groove 122, thereby improving the reliability of the injection molding 100.
Wherein, the groove depth H of the bending groove can be 1 mm-1.5 mm. And the groove depths H of the first bending groove 112 and the second bending groove 122 may be the same or different, which is not limited herein.

Preferably, in the case where the shape of the bending groove is a V-groove, the V-angle θ of the V-groove may be set to 100 ° -140 °, so that the formation of the outer protrusion at the bending portion is further prevented by the bending groove angle setting, thereby improving the reliability of the injection molding 100. And the V-shaped angle θ of the first bending groove 112 and the second bending groove 122 may be the same or different, which is not particularly limited herein. For example, the V-shaped angle θ of each of the first bending groove 112 and the second bending groove 122 is 120 °.
