Description

Technical Field

[0001] This utility model relates to a riveting positioning fixture, and more particularly to a positioning fixture for riveting locking accessories of rectangular connectors. Background Technology

[0002] like Figure 1 As shown, the connector (referred to as an electrical connector in this document) includes a connector housing 1 and contacts (not visible in the figure, generally including pins and / or sockets) placed inside the connector housing 1. A connector with a rectangular connector housing 1 is called a rectangular connector. For ease of application, tubular rivet sleeves 3 are often installed on the connector housing 1 near both ends by riveting. One end of the rivet sleeve 3 has a protruding, smaller-diameter, tubular rivet head 2. The rivet head 2 is passed through the corresponding mounting hole on the connector housing 1, and then riveted with a tool to achieve the riveting between the rivet sleeve 3 and the connector housing 1.

[0003] Before riveting, the rivet sleeve 3 is usually positioned using a positioning fixture. The traditional positioning fixture includes a base and a support column on the base. When riveting, a rivet sleeve 3 is placed on the support column, and then the mounting hole of the connector housing 1 is put onto the rivet head 2. One hand holds the rivet head, and the other hand holds a hammer. The hammer is used to strike the rivet head to complete the riveting work.

[0004] The aforementioned traditional positioning fixture has the following drawbacks: one positioning installation can only complete the riveting of one rivet sleeve 3 to the connector housing 1, and two rivet sleeves 3 require two positioning installations, which reduces processing efficiency; during the riveting process, due to the gravity of the connector housing 1, one person cannot keep the rivet sleeve 3 and the connector housing 1 perpendicular to each other, and even if another person holds the connector housing 1, it is not easy to achieve this goal, and the connector housing 1 is prone to rotating around the rivet sleeve 3, and the rivet sleeve 3 is prone to cracking due to the pressure of the flange on one side, which poses a risk of falling off later, reducing the quality and efficiency of riveting; in addition, the aforementioned traditional positioning fixture can only be used for connector housings 1 without tail clamps, which limits its application. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for riveting rectangular connector locking accessories, which can complete the riveting operation of two rivet sleeves to the connector housing after one positioning and installation, in order to solve the above problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A positioning fixture for riveting locking accessories of rectangular connectors includes a horizontal base plate, a horizontal top plate, and a vertical support column. The top plate is located above the base plate and connected to it. The top plate has a strip-shaped groove. The top plate has a non-circular vertical through hole and a vertical through strip-shaped through hole. The vertical through hole is close to one closed end of the strip-shaped through hole and is located on the extension line of the length of the strip-shaped through hole. Both the vertical through hole and the strip-shaped through hole are located directly above the strip-shaped groove. The lower end of the support column, which has a non-circular radial cross-section, has a support column protrusion ring protruding outward in the circumferential direction, and the middle of the upper end has an upward protrusion cylinder with a decreasing outer diameter. The support column protrusion rings of the two support columns are placed in the strip-shaped groove. One support column passes through the vertical through hole and cannot move laterally or rotate around its own center line. The other support column passes through the strip-shaped through hole and cannot rotate around its own center line.

[0008] Preferably, in order to achieve the anti-rotation function of the support column, the two opposite sides of the support column are vertical planes forming vertical side planes, and the two vertical side planes of the support column passing through the strip-shaped through hole respectively contact the two longitudinal hole walls of the rectangular strip-shaped through hole.

[0009] Preferably, in order to make this tooling applicable to connector housings with tail clips, the adjacent side surfaces of the two support columns form vertically opposite planes, which are flush with the corresponding outer wall surface of the corresponding cylinder in the vertical direction.

[0010] Preferably, in order to cooperate with the support column to achieve the anti-rotation function, the surface of the hole wall on the vertical through hole that corresponds to the vertical plane of the corresponding support column is a vertical plane.

[0011] Preferably, in order to quickly and reliably connect the base plate and the top plate, four screws are respectively passed through the top plate through holes near the four corners of the top plate and then connected to the base plate screw holes near the four corners of the base plate.

[0012] The beneficial effects of this utility model are as follows:

[0013] This invention utilizes a design with a base plate, an upper plate, and two supporting columns that work together to ensure that one supporting column is immovable while the other can move and be positioned. During use, both supporting columns can be positioned simultaneously for connector housings of different sizes. During the riveting process, two rivet sleeves can be installed on the cylinders of the two supporting columns, with the rivet heads of the two sleeves passing through mounting holes near both ends of the connector housing. This allows for riveting of both sleeves in a single positioning and installation, improving processing efficiency. Furthermore, the connector housing does not rotate or tilt during riveting, maintaining a perpendicular position to the supporting columns. One person can complete the riveting operation. The rivet heads of the sleeves are evenly stressed, preventing cracks and ensuring a stable and reliable riveting connection, thus improving both riveting quality and efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings:

[0021] like Figure 2 and Figure 3As shown, the positioning fixture for riveting locking accessories of rectangular connectors according to this utility model includes a horizontal base plate 4, a horizontal upper plate 13, and a vertical support column 8. The upper plate 13 is located above the base plate 4 and connected to it. A strip groove 14 is provided on the upper surface of the base plate 4. The upper plate 13 has a non-circular vertical through hole 12 and a vertical through strip hole 15. The vertical through hole 12 is close to one closed end of the strip hole 15 and is located on the extension line of the length of the strip hole 15. Both the vertical through hole 12 and the strip hole 15 are located in the strip groove 14. Directly above 4, the lower end of the support column 8, which has a non-circular radial cross section, is provided with a support column protrusion ring 11 that protrudes outward in the circumferential direction, and the upper middle part is provided with a cylinder 7 that protrudes upward and has a reduced outer diameter. The support column protrusion rings 11 of the two support columns 8 are both placed in the strip-shaped sink 14. The upper surface of the support column protrusion ring 11 is not lower than (preferably slightly higher than) the upper surface of the bottom plate 4. One of the support columns 8 passes through the vertical through hole 12 and cannot move laterally or rotate around its own center line. The other support column 8 passes through the strip-shaped through hole 15 and cannot rotate around its own center line.

[0022] like Figure 2 and Figure 3 As shown, this utility model also discloses the following more optimized specific structures:

The two vertical side planes 10 of the support column 8 passing through the strip-shaped through hole 15 respectively contact the two longitudinal hole walls of the rectangular strip-shaped through hole 15.

[0024] In order to make this tooling applicable to connector housings with tail clips, the adjacent surfaces of the two support columns 8 form vertical planes 9, which are flush with the corresponding outer wall surfaces of the corresponding cylinders 7 in the vertical direction.

[0025] In order to cooperate with the support column 8 to achieve the anti-rotation function, the surface of the hole wall on the vertical through hole 12 that corresponds to the vertical plane 9 of the corresponding support column 8 is a vertical plane.

[0026] In order to quickly and reliably connect the base plate 4 and the upper plate 13, four screws 5 are respectively passed through the upper plate through holes 16 near the four corners of the upper plate 13 and connected to the base plate screw holes 6 near the four corners of the base plate 4.

[0027] like Figures 2-5As shown, in application, first loosen screw 5. Based on the dimensions of connector housing 1, move the support post 8 passing through the strip-shaped through hole 15 so that the lateral distance between it and the other support post 8 is the same as the distance between the two mounting holes on connector housing 1 that need to be riveted. Then tighten screw 5, using the upper plate 13 to press down the support post protrusions 11 of the two support posts 8 to achieve positioning of the two support posts 8. Then, fit the two rivet sleeves 3 onto the cylinders 7 of the two support posts 8. Then, fit the connector housing 1 through its two mounting holes onto the rivet heads 2 of the two rivet sleeves 3 respectively, thus completing the installation of the connector housing 1 on this positioning fixture. Then, hold the rivet head in one hand and a hammer in the other, and use the hammer to strike the two rivet heads 2 to complete the riveting connection operation between the two rivet sleeves 3 and the connector housing 1. During the entire riveting process, it is not necessary to hold the connector housing 1 with your hand. The connector housing 1 and the two rivet sleeves 3 are perpendicular to each other and cannot rotate. The rivet head 2 is subjected to uniform force, improving the riveting quality and efficiency.
