Description

Technical Field

[0001] The utility model relates to the technical field of relays, in particular to a support structure and a relay. Background Art

[0002] Refer to the attached Figure 6 to the attached Figure 9 As shown in the attached drawings, a static contact support 1' of an existing electromagnetic relay is provided with a plurality of grooves 11' for fixing a stop piece 2 and a static contact 3. The distribution of these grooves 11' on the static contact support 1' is asymmetric and the depths are different. Among them, the grooves 11' on the left side are shorter in length and shallower in depth, while the grooves 11' on the right side are longer in length and deeper in depth. In a preferred implementation, the depth of the left groove 11' is 2.1 mm, and the depth of the right groove 11' is 3 mm. When the static contact support is demolded from the moving die of the mold during the production process, the left side is demolded earlier than the right side, and the deep groove on the right side is not the structural center of the static contact support 1'. Therefore, when the ejection stroke is between 2.1 mm and 3 mm, since the grooves on the left side have been demolded while the grooves on the right side have not been demolded, thus, the static contact support is prone to shift under this ejection stroke, resulting in unbalanced force during the ejection process, and further prone to the problem of material drawing at the notch of the groove 11' on the right side. Summary of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a support structure, which mainly solves the technical problem that the existing static contact support is prone to shift during the demolding process, thereby causing damage to the notch of the product.

[0004] To achieve the above object, the utility model is realized through the following technical solutions:

[0005] A support structure includes a support body. An installation groove is formed on the support body, and a slotted opening is further formed on the support body opposite to the installation groove. The slotted opening is configured to cooperate with the installation groove during the demolding and ejection process of the support body to achieve balanced ejection of the support body.

[0006] Furthermore, the support body at least includes a main body part. The installation groove and the slotted opening are both formed on the main body part and are diagonally arranged.

[0007] Furthermore, a plurality of installation grooves are formed on the main body part, and an eccentric deep groove which is deviated from the structural center of the main body part and has the deepest depth is defined. The midpoint of the connection line between the center of the slotted opening and the center of the eccentric deep groove is configured to fall within the range of the structural center area of the main body part.

[0008] Furthermore, the ratio of the groove depth of the slotted opening on the main body part to the groove depth of the eccentric deep groove is (0.9 - 1.1):1.

[0009] Further, the range of the structural central region of the main body part refers to the part within the radiation region with the structural center point of the main body part as the center of a circle and a radius of r; preferably, the main body part has a rectangular structure. Define the length of the main body part as L1, the width as L2, the area of the main body part as S1 = L1 * L2, and the area S2 of the range of the structural central region of the main body part as π * r2, then S2:S1 ≤ 0.1:1.

[0010] Further, the eccentric deep groove is configured to be located at one side edge of the main body part and is used for installing the stop piece or the static contact of the relay.

[0011] Further, the support structure is the static contact support of the relay, and the parts of the support body in the installation grooves other than the eccentric deep groove are configured to install the static contact of the relay.

[0012] Further, the slot is a circular slot hole structure.

[0013] Further, the slot is a square slot hole structure.

[0014] Based on the same inventive concept, the present utility model also provides a relay, including the support structure described in any one of the above.

[0015] The above technical solutions have the following advantages or beneficial effects:

[0016] In the support structure and the relay of the present utility model, a slot is opened on the support body opposite to the installation groove. By setting the slot and the mutual cooperation between the slot and the installation groove, a balancing effect is generated on the demolding process of the support body, effectively improving the problem that the notch is damaged due to the skew caused by unbalanced ejection during the demolding of the support body. And, by setting the slot, the injection molding material consumption of the support structure can be reduced to a certain extent, which is beneficial to reducing its production cost.
