[0021] The present invention will be further explained below in conjunction with specific implementation schemes, but the present invention is not limited thereto.

[0022] In the prior art, the angle of the riveting key and the magnitude of the applied force cannot be precisely controlled. It can only be inspected based on the experience of workers and the actual effect after riveting. Generally, three rivets are riveted on each product. If one of the rivets becomes loose due to insufficient riveting force or the rivet head cracks due to excessive riveting force or angle, the entire electrical connector housing will be scrapped. Riveting looseness or cracking will not only affect the structural dimensions of the product and thus the docking performance, but also reduce the airtightness of the electrical connector product that needs to be sealed, and even pose a risk of rivet detachment during the subsequent use of the product. Therefore, the control of the riveting key process is very necessary.

[0023] For this reason, this implementation provides a riveting key device for an electrical connector housing, as Figure 1 described, including a high-hardness indenter 1, a square gasket 3, a riveting key base 5, a vertical pressure rod 4, a horizontal pressure rod 6, a stop piece 7, a circular gasket 8, a compression spring 9, and a mounting plate 10;

[0024] The riveting key base 5 is fixed on the mounting plate 10;

[0025] A guide groove cavity is provided in the riveting key base 5. The vertical pressure rod 4, the stop piece 7, the compression spring 9, and the circular gasket 8 are arranged in the guide groove cavity from top to bottom in sequence. The vertical pressure rod 4 and the stop piece 7 are fixedly connected, and the bottom of the compression spring 9 is embedded in the circular gasket; the vertical pressure rod 4 and the stop piece 7 can slide freely in the guide groove cavity together;

[0026] When not under pressure, the vertical pressure rod 4 rises to the highest height through the compression spring 9. When under pressure, the stop piece 7 contacts the circular gasket 8 to protect the compression spring 9 from being compressed to the compression limit and ensure the normal operation of the pressure spring. By calculating and adjusting the height of the compression spring and the circular gasket, the indenter 1 of the riveting key can be automatically bounced back to its original position after pressing down in place, facilitating the next riveting key operation.

[0027] The horizontal pressure rod 6 is installed on the vertical pressure rod 4 and can move on the vertical pressure rod 4; a riveting key groove 2 is also provided on the riveting key base 5; the high-hardness indenter 1 is installed in the mounting hole at one end of the horizontal pressure rod 6, and the center line of the high-hardness indenter 1 and the riveting key groove 2 are on a vertical line to ensure that the pressure direction is vertically downward during the riveting operation;

[0028] The square gasket 3 is installed on the riveting key base 5 and is used to clamp the housing 11 of the electrical connector product, so that the mounting hole of the housing 11 falls within the riveting key groove 2. The thickness of the square gasket 3 is designed according to the horizontal distance from the mounting plate of the housing 11 of the electrical connector product to the riveting key hole, ensuring that when the mounting plate is aligned with the square gasket, the mounting hole of the housing just falls within the riveting key groove 2.

[0029] The vertical pressure rod 4 and the stop piece 7 are fixedly connected by a screw.

[0030] The stop piece 7, the circular gasket 8 and the compression spring 9 can all have multiple heights.

[0031] The horizontal pressure rod 6 is installed on the vertical pressure rod 4 by a setscrew; installing the horizontal pressure rod 6 on the upper end of the vertical pressure rod 4 by a setscrew can freely adjust the height of the horizontal pressure rod 6 to meet the riveting requirements of various products;

[0032] The riveting key groove 2 is connected to the riveting key base 5 by screws, and the riveting key groove can be adjusted according to the size of the required rivet, so that the size of the riveting key groove can just accommodate the rivet 12 to be riveted;

[0033] The square gasket 3 has multiple thicknesses, and the high-hardness indenter 1 has multiple specifications. The thickness of the square gasket 3 is designed according to the horizontal distance from the mounting plate of the housing 11 of the electrical connector product to the riveting key hole, ensuring that when the mounting plate abuts against the square gasket, the housing mounting hole can just fall into the riveting key groove 2.

[0034] For rivets of different specifications, corresponding indenter 1 and riveting key groove 2 can be prepared in advance; for different structural housings of the same kind of rivet, only the corresponding square gasket 3 needs to be designed according to the housing size to be used normally.

[0035] As Figures 2-3 shown, this embodiment provides an assembly step and a use method of a riveting key device for an electrical connector housing, specifically including:

[0036] Step 1: Connect the vertical pressure rod 4 and the stop piece 7 with bolts. At the same time, install the compression spring 9 and the circular gasket 8 into the riveting key base 5 in sequence, and then fix the riveting key base on the mounting plate 10 with four bolts.

[0037] Step 2: Install the rivet 12 into the corresponding riveting key groove 2, and then install the square gasket 3 corresponding to the electrical connector product housing 11 on the riveting key base 5 with two bolts. Place the electrical connector product housing 11 so that the housing mounting hole can just fall into the riveting key groove 2.

[0038] Step 3: Screw the indenter 1 into the horizontal pressure rod 6. At the same time, pass the horizontal pressure rod 6 through the vertical pressure rod 4, and adjust the height of the horizontal pressure rod 6 so that when the compression spring 9 is in the downward pressure state, the indenter 1 can just effectively rivet the rivet 12. At this time, lock the setscrew on the horizontal pressure rod 6 to perform the riveting key work.

[0039] Step 4: Install the product rivet 12 into the riveting key groove 2, and align one end of the mounting plate of the electrical connector product housing 11 with the square gasket 3, and at the same time make the mounting hole just fall on the rivet 12.

[0040] Step 5: Use a press to control the pressure to be approximately 0.3 - 0.6 MPa, and press down the vertical pressure rod 4 of the riveting key tooling in Step 4 for 1 - 3 seconds. At this time, the compression spring 9 inside the riveting key is pressed down, and the stop piece 7 contacts the circular gasket 8 and is pressed to the lowest position; the external vertical pressure rod 4 of the tooling drives the horizontal pressure rod 6 and the pressing head 1 to press down the rivet 12, so that the rivet 12 is turned and riveted onto the electrical connector product housing 11; lift the press. Due to the action of the compression spring 9, the vertical pressure rod 4 drives the horizontal pressure rod 6 and the pressing head 1 to rise. At this time, take out the electrical connector product housing 11, and the rivet 12 is riveted into it. At this time, the riveting key tooling is reset, and the riveting key process is completed.

[0041] Step 6: Repeat Step 5 twice to continue turning and riveting the remaining two rivets 12 onto the electrical connector product housing 11. At this time, the riveting of the entire product is completed.

[0042] The riveting key device for the electrical connector housing provided by this implementation scheme can perform riveting keys on deep cavity housings, special-shaped parts, small-sized parts, etc., meet the actual production requirements of riveting keys for the vast majority of electrical connector housings, ensure the consistency and stability of product riveting keys, and at the same time improve production efficiency and product qualification rate.

[0043] The specific implementation manners of the present utility model are written in a progressive manner, emphasizing the differences between each implementation scheme, and the similar parts can be referred to each other.

[0044] The above has described in detail the implementation manners of the present utility model in conjunction with the drawings. However, the present utility model is not limited to the above implementation manners, and various changes can be made without departing from the purpose of the present utility model within the knowledge scope of those of ordinary skill in the art.
