Description

Technical Field

[0001] The utility model relates to a rubber stacking fixture for an electric connector, belonging to the technical field of electric connector manufacturing. Background Art

[0002] In order to meet the moisture-proof performance requirements of the electrical connector, after completing the welding work of the electrical connector according to the design requirements, it is necessary to use a fixture or tooling to stack or pour glue on the tail end to form a glue block to protect the wires at the tail end of the electrical connector.

[0003] For example, a Chinese patent document with publication number CN215088539U discloses a non-sealed connector glue pouring tooling, which includes two half-molds, each of which is provided with a fastening part for clamping the electrical connector and a glue blocking part for glue pouring. The tooling is made of nylon material and does not stick to the glue. After the glue is cured, the tooling can be easily removed.

[0004] However, after the two half molds are fastened together with screws to clamp the electrical connector, it is difficult to close the joints of the two half molds tightly, and a large gap will exist. During the glue pouring process, the glue will leak from the joints of the two half molds, forming excess material on the surface of the solidified colloid, which needs to be cleaned up later, resulting in a decrease in the glue pouring efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an electrical connector glue stacking fixture.

[0006] The utility model is realized through the following technical solutions:

[0007] A rubber stacking fixture for an electrical connector comprises a rubber stacking block A and a rubber stacking block B, wherein the rubber stacking block A is provided with a rectangular notch, the bottom surface of the rectangular notch is provided with a rubber stacking groove A, and both side walls of the rectangular notch are provided with semicircular grooves A, the distance from the semicircular groove A to the bottom surface of the rectangular notch is M, and the distance takes a negative tolerance, the rubber stacking block B is located in the rectangular notch, the rubber stacking block B is provided with a rubber stacking groove B at a position corresponding to the rubber stacking groove A, and the rubber stacking block B is provided with a semicircular groove B at a position corresponding to the semicircular groove A, the distance from the semicircular groove B to the side surface of the rubber stacking block B with the rubber stacking groove B is N, and the distance takes a positive tolerance, and the rubber stacking block B is connected to the rubber stacking block A through a connecting piece.

[0008] The semicircular grooves A on the two side walls of the rectangular notch are arranged symmetrically.

[0009] The connecting piece is inserted into the hole surrounded by the semicircular groove A and the semicircular groove B.

[0010] The connecting piece is a positioning pin, and one end of the positioning pin is chamfered.

[0011] The length, width and height of the rubber stacking block B are consistent with the length, width and height of the rectangular slot.

[0012] A positioning groove A is provided on the bottom surface of the rectangular notch, and a positioning groove B is provided at a position corresponding to the positioning groove A on one side of the rubber stacking block B where the rubber stacking groove B is provided.

[0013] The beneficial effect of the utility model is that the rubber block B is closed with the rubber block A, and the electrical connector is embraced by the rubber groove A on the rubber block A and the rubber groove B on the rubber block B, and then the connecting piece is inserted into the hole surrounded by the semicircular groove A and the semicircular groove B, so that the rubber block A and the rubber block B embrace the electrical connector. At the same time, since the distance from the semicircular groove A to the bottom surface of the rectangular notch is M and a negative tolerance is taken, the distance from the semicircular groove B to the side surface of the rubber block B with the rubber groove B is N and a positive tolerance is taken, the connecting piece pushes the rubber block B to move as close to the electrical connector as possible, so that the side surface of the rubber block B with the rubber groove B is closely attached to the bottom surface of the rectangular notch, which greatly reduces the gap between the side surface of the rubber block B and the bottom surface of the rectangular notch, thereby avoiding the phenomenon of glue leakage in the gap during the glue stacking process, further avoiding the formation of excess material of the glue stacking body in the gap, eliminating the subsequent work of cleaning up the excess material, and helping to improve the glue stacking efficiency.

[0020] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0021] like Figures 1 to 5As shown, a rubber stacking fixture for an electrical connector described in the utility model includes a rubber stacking block A1 and a rubber stacking block B2, wherein a rectangular notch 12 is provided on the rubber stacking block A1, a rubber stacking groove A14 is provided on the bottom surface of the rectangular notch 12, and semicircular grooves A11 are provided on both side walls of the rectangular notch 12, and the distance from the semicircular groove A11 to the bottom surface of the rectangular notch 12 is M, and the distance is negative tolerance, the rubber stacking block B2 is located in the rectangular notch 12, and a rubber stacking groove B22 is provided on the rubber stacking block B2 at a position corresponding to the rubber stacking groove A14, and a semicircular groove B23 is provided on the rubber stacking block B2 at a position corresponding to the semicircular groove A11, and the distance from the semicircular groove B23 to the side of the rubber stacking block B2 with the rubber stacking groove B22 is N, and the distance is positive tolerance, and the rubber stacking block B2 is connected to the rubber stacking block A1 through a connector 3. When in use, the basic dimensions of M and N are equal. The rubber block B2 is closed with the rubber block A1, and the electrical connector is held by the rubber groove A14 on the rubber block A1 and the rubber groove B22 on the rubber block B2, and then the connector 3 is inserted into the hole surrounded by the semicircular groove A11 and the semicircular groove B23, so that the rubber block A1 and the rubber block B2 hold the electrical connector tightly. At the same time, since the distance from the semicircular groove A11 to the bottom surface of the rectangular notch 12 is M and a negative tolerance is taken, the distance from the semicircular groove B23 to the side of the rubber block B2 with the rubber groove B22 is N and taking a positive tolerance, the connector 3 will push the rubber stacking block B2 to move as close to the electrical connector as possible, so that the side of the rubber stacking block B2 with the rubber stacking groove B22 is tightly fitted on the bottom surface of the rectangular notch 12, which greatly reduces the gap between the side of the rubber stacking block B2 and the bottom surface of the rectangular notch 12, thereby avoiding glue leakage in the gap during the glue stacking process, and further avoiding the formation of excess glue in the gap, eliminating the subsequent work of cleaning up the excess, which helps to improve the glue stacking efficiency.

[0022] The semicircular grooves A11 on the two side walls of the rectangular notch 12 are arranged symmetrically.

[0023] The connecting member 3 is inserted into the hole surrounded by the semicircular groove A11 and the semicircular groove B23.

[0024] The connecting member 3 is a positioning pin, and one end of the positioning pin is chamfered.

[0025] The length, width and height of the rubber stacking block B2 are consistent with the length, width and height of the rectangular slot 12 .

[0026] A positioning groove A13 is provided on the bottom surface of the rectangular notch 12, and a positioning groove B21 is provided on one side of the rubber stacking block B2 at a position corresponding to the positioning groove A13. When in use, the positioning groove A13 and the positioning groove B21 are used to position the flange plate on the electrical connector and clamp the flange plate to prevent the electrical connector from moving up and down during the rubber stacking process.
