Abstract
Description
Technical Field
[0001] This application relates to the field of radio frequency connector assembly, and in particular to a fixture for simultaneous assembly of multiple processes of radio frequency connectors. Background Art
[0002] A radio frequency connector is a component installed on a cable or on an instrument. As a component for electrical connection or separation of a transmission line, it belongs to an electromechanical integration product and mainly plays a bridging role. A radio frequency connector mainly consists of a body, a center pin, and an insulator.
[0003] Currently, the assembly of the body, center pin, and insulator of a radio frequency connector is usually carried out manually. It is necessary to manually assemble the center pin onto the semi-finished product card slot of the radio frequency connector in sequence, then press it down by a hand press, then manually assemble the insulator and press it down, and finally assemble and press the body to obtain the finished radio frequency connector. However, the method of sequentially assembling multiple components step by step will consume a large amount of time, resulting in low assembly efficiency of the radio frequency connector and difficult to produce efficiently. Utility Model Content
[0004] In order to improve the assembly efficiency of radio frequency connectors, this application provides a fixture for simultaneous assembly of multiple processes of radio frequency connectors.
[0005] The fixture for simultaneous assembly of multiple processes of radio frequency connectors provided by this application adopts the following technical solution:
[0006] A fixture for simultaneous assembly of multiple processes of radio frequency connectors includes a base, a fixture, a press tool, an upper shell, and an elastic member. The fixture is arranged on the base and is used for the center pin to be inserted. The press tool is slidably arranged on the base. An assembly space for the insulator to be inserted is formed between the press tool and the fixture. The press tool is used for the body to be inserted. The upper shell is arranged on the press tool and is used for the semi-finished product to be inserted and docked with the center pin, insulator, and body. The elastic member is arranged on the base and is used to drive the press tool to reset.
[0007] By adopting the above technical solution, the staff places the base on the hand press, inserts the center pin into the fixture, then inserts the insulator into the assembly space formed between the press tool and the fixture, then inserts the body into the press tool, and finally inserts the semi-finished product into the upper shell, so that the semi-finished product is docked with the center pin, insulator, and body. Then, the hand press is used to press the upper shell, and the upper shell drives the press tool to slide towards the direction close to the base, so that the center pin, insulator, column, and semi-finished product can be combined to form a finished radio frequency connector by extrusion. Then, the elastic member drives the press tool to reset, waiting for the next assembly, realizing the synchronous progress of multiple processes, effectively improving the assembly efficiency of radio frequency connectors and shortening the production cycle of radio frequency connectors.
[0008] Optionally, a limiting strip hole is provided on the upper shell along the sliding direction of the press tool, and a limiting post is provided on the base. The limiting post is slidably arranged on the inner wall of the limiting strip hole.
[0009] By adopting the above technical solution, during the sliding process of the upper shell, the limiting post slides in the limiting strip hole, and the side wall of the limiting strip hole limits the limiting post, thereby guiding the sliding of the upper shell and the press tool, improving the assembly accuracy, reducing the assembly error, and ensuring the assembly quality of the radio frequency connector.
[0010] Optionally, the upper shell is slidably sleeved on the outer wall of the base.
[0011] By adopting the above technical solution, the outer wall of the base guides the sliding of the upper shell, further improving the stability of the upper shell during the sliding process.
[0012] Optionally, a positioning groove for the semi-finished product to be inserted is provided on the upper shell.
[0013] By adopting the above technical solution, when the semi-finished product is inserted into the upper shell, the semi-finished product can be inserted into the positioning groove, improving the stability of the semi-finished product on the upper shell.
[0014] Optionally, the elastic member includes a spring. The spring is arranged on the base and connected to the upper shell, and the spring always has a tendency to drive the upper shell away from the base.
[0015] By adopting the above technical solution, during the process of the upper shell being pressed down, the spring provides buffering for the upper shell, reducing the impact of the upper shell and the press tool on the center pin, insulator, column body, and semi-finished product during the pressing down process, thereby reducing the possibility of damage to the center pin, insulator, column body, and semi-finished product, and improving the qualified rate; after the pressing down is completed, the upper shell and the press tool can be driven away from the base for resetting.
[0016] Optionally, a positioning hole for the lower die of the hand press to be inserted is provided on the base.
[0017] By adopting the above technical solution, when the base is placed at the hand press, the lower die of the hand press can be inserted into the positioning hole, thereby positioning the base and improving the stability of the base on the hand press.
[0018] Optionally, a guiding groove is provided on the base, and the press tool is slidably attached to the side wall of the guiding groove.
[0019] By adopting the above technical solution, the side wall of the guiding groove guides the press tool, improving the stability of the press tool during the sliding process.
[0020] Optionally, a locking hole is provided on the base, and a perforation is provided on the upper shell. When the upper shell slides to the maximum limit away from the base, the perforation is aligned with the locking hole.
[0021] By adopting the above technical solution, after the assembly is completed, the spring drives the pressing tool to drive the upper shell to reset. When the upper shell slides to the maximum limit away from the base, the worker passes the pin or bolt through the perforation and into the locking hole, and then the upper shell can be positioned on the base, improving the stability of the upper shell and the pressing tool, reducing the acting force of the upper shell and the pressing tool on the spring, and prolonging the service life of the spring.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. The hand press presses the upper shell, and the upper shell drives the pressing tool to slide in the direction close to the base.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0030] The following further Figures 1-3 describes the present application in detail with reference to the
[0031] Embodiments of the present application disclose a multi-process simultaneous assembly jig for a radio frequency connector.
[0032] Refer to Figure 1 , Figure 2, The multi-process simultaneous assembly fixture for a radio frequency connector includes a base 1, a fixture 2, a press tool 3, an upper shell 4, an elastic member 5, and a limit post 7.
[0033] Referring to Figure 2 , a positioning hole 11 is opened below the base 1, and the positioning hole 11 is used for the lower die of the hand press to insert. When the staff places the base 1 on the hand press, the lower die of the hand press is inserted into the positioning hole 11, and the side wall of the positioning hole 11 limits the lower die of the hand press, thereby positioning the base 1 on the hand press and effectively improving the stability of the base 1 on the hand press.
[0034] Referring to Figure 2 , a guiding groove 12 is vertically opened at the upper end of the base 1, the fixture 2 is installed on the bottom wall of the guiding groove 12, and an adaptation groove for the center pin to be inserted is opened on the fixture 2. When the staff inserts the center pin into the adaptation groove, the center pin can be positioned and assembled onto the fixture 2.
[0035] Referring to Figure 2 , the press tool 3 slides vertically and fits on the side wall of the guiding groove 12, an assembly space 6 is formed between the press tool 3 and the fixture 2, the assembly space 6 is used for the insulator to be inserted, a through hole for the main body to be inserted is opened above the press tool 3, and the through hole is communicated with both the assembly space 6 and the adaptation groove on the fixture 2.
[0036] The staff inserts the insulator into the assembly space 6 formed between the press tool 3 and the fixture 2, and then inserts the main body into the through hole opened above the press tool 3, thus completing the assembly of the insulator and the main body and enabling the center pin, the insulator, and the main body to be docked according to the assembly positions; during subsequent assembly under the pressing action of the hand press, the side wall of the guiding groove 12 guides the sliding of the press tool 3, effectively improving the stability of the press tool 3 during the sliding process, and further improving the accuracy of pressing the center pin, the insulator, and the main body.
[0037] Referring to Figure 1 , Figure 2 , the upper shell 4 is installed on the press tool 3, a hole for the semi-finished product to be inserted is opened on the upper shell 4, the hole is communicated with the through hole on the press tool 3, and a positioning groove 42 for the semi-finished product to be inserted is also opened on the upper shell 4. Through the positioning of the semi-finished product by the positioning groove 42 and the hole, the accuracy and stability of the docking of the semi-finished product with the center pin, the insulator, and the main body on the upper shell 4 are effectively improved.
[0038] Referring to Figure 1 , Figure 2 , the upper shell 4 is slidably sleeved on the outer wall of the base 1, a limit strip hole 41 is opened on the upper shell 4 along the sliding direction of the press tool 3, the limit post 7 is installed on the outer wall of the base 1, the limit post 7 slides in the limit strip hole 41, and the diameter of the limit post 7 is the same as the opening width of the limit strip hole 41.
[0039] When the hand press presses the upper shell 4 and the upper shell 4 drives the pressing tool 3 to slide, the outer wall of the base 1 guides the sliding of the upper shell 4. At the same time, the limit post 7 slides in the limit strip hole 41, and the inner wall of the limit strip hole 41 limits the limit post 7, so that the upper shell 4 can only slide along the sliding direction of the pressing tool 3, effectively improving the sliding stability of the upper shell 4 and the pressing tool 3. Moreover, the limit strip hole 41 can also limit the stroke of the up and down sliding of the pressing tool 3, improving the accuracy of the upper shell 4 and the pressing tool 3 for pressing the center pin, insulator, main body and semi-finished product, improving the assembly accuracy, reducing the assembly error, and ensuring the assembly quality of the radio frequency connector.
[0040] Refer to Figure 2 As shown in the figure, the elastic member 5 is installed on the base 1. The elastic member 5 is used to drive the pressing tool 3 to reset. The elastic member 5 includes a spring 51. One end of the spring 51 is installed on the bottom wall of the guide groove 12, and the other end of the spring 51 is connected to the upper shell 4. And the spring 51 is wound around the outer periphery of the pressing tool 3. The spring 51 always has a tendency to drive the upper shell 4 to slide away from the base 1.
[0041] When the hand press presses down the upper shell 4, the spring 51 provides buffering for the downward movement of the upper shell 4 and at the same time provides buffering for the downward movement of the pressing tool 3, reducing the impact of the upper shell 4 and the pressing tool 3 on the center pin, insulator, column and semi-finished product during the downward pressing process, thereby reducing the possibility of damage to the center pin, insulator, column and semi-finished product and improving the yield rate. After the upper shell 4 and the pressing tool 3 complete the downward pressing, the spring 51 resets and drives the upper shell 4 and the pressing tool 3 to move away from the base 1 for reset.
[0042] Refer to Figure 1 、 Figure 3 As shown in the figure, a locking hole 13 is horizontally opened on the base 1, and a through hole 43 is horizontally opened on the upper shell 4. When the upper shell 4 slides to the maximum limit away from the base 1, the through hole 43 is directly opposite to the locking hole 13. After the radio frequency connector is assembled, the spring 51 drives the upper shell 4 and the pressing tool 3 to move away from the base 1 to the maximum limit. At this time, the through hole 43 and the locking hole 13 are directly opposite. At this time, the staff can insert a pin or a bolt through the through hole 43 and into the locking hole 13 to lock the upper shell 4 and the base 1 through the pin or the bolt, improving the stability of the upper shell 4 and the pressing tool 3 on the base 1, reducing the acting force of the upper shell 4 and the pressing tool 3 on the spring 51 when not assembled, and improving the service life of the spring 51.
[0043] The implementation principle of a multi-process simultaneous assembly fixture for a radio frequency connector in an embodiment of the present application is as follows: The staff positions and assembles the base 1 onto the lower die of a hand press, then clips the center pin into the fixture 2, then clips the insulator into the assembly space 6 formed between the press tool 3 and the fixture 2, then clips the main body into the press tool 3, and finally clips the semi-finished product into the upper shell 4, so that the semi-finished product, the center pin, the insulator, and the main body are butted according to the assembly positions. Then, the hand press presses down onto the upper shell 4, and the upper shell 4 drives the press tool 3 to press down towards the direction close to the base 1, and thus a finished radio frequency connector can be formed by combining the center pin, the insulator, the column body, and the semi-finished product. During the pressing process, the spring 51 provides buffering and drives the upper shell 4 and the press tool 3 to reset after the pressing is completed, thereby realizing the synchronous progress of multiple processes, effectively improving the assembly efficiency of the radio frequency connector, shortening the production cycle of the radio frequency connector, and precisely guiding the upper shell 4 and the press tool 3 during the pressing process, effectively improving the assembly precision, reducing the assembly error, and ensuring the assembly quality of the radio frequency connector.
[0044] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
