Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to an electrical connector pin assembly. Background Technology

[0002] Electrical connectors, also known as plugs and sockets, are widely used in various electrical circuits to connect or disconnect circuits. They are electronic components that enable electrical connections between devices and components.

[0003] Traditional devices have significant shortcomings when dealing with radially distributed sockets. First, they lack an effective radial positioning mechanism, causing the pins to easily deviate from their preset positions due to radial deformation during insertion, resulting in poor contact between the socket and the pin or abnormal insertion and extraction forces. Second, their fixing structure is simple and cannot adapt to radial socket layouts of different sizes, resulting in poor versatility. Summary of the Invention

[0004] The purpose of this application is to provide an electrical connector pin device to solve the above problems. It adopts a connector positioning measure that can be driven to move and rotate, which can clamp different types of electrical connectors and ensure that the pins are coaxial with the sockets, thus achieving precise positioning. These improvements not only improve assembly efficiency and yield, but also support the high-density connector requirements with complex radial layouts.

[0005] This application achieves the above objectives through the following technical solutions:

[0006] An electrical connector pin assembly includes: a rotary feeder with multiple sets of connector positioning components distributed circumferentially along its upper edge;

[0007] The connector positioning assembly includes a slide rail, a slider, a guide rod, a return spring, and a connector placement base;

[0008] The rotary feeder is equipped with a chute, with fixed slide rails on both sides of the chute. The slider slides in cooperation with the slide rails and can move linearly along the chute.

[0009] One end of the slider is provided with a guide rod mounting hole, the guide rod is detachably connected to this end, and a return spring is sleeved on the outside of the guide rod to push the slider to return to its original position;

[0010] The connector holder is rotatably connected to the slider, with an open top to accommodate the electrical connector and a tapered bottom to expose the socket at the bottom of the electrical connector.

[0011] The slider is composed of a first slider part and a second slider part, which are fixed together by through bolts;

[0012] The rotary feeder is equipped with a hole adjustment and positioning assembly, which includes an electric slide, a short-stroke telescopic cylinder, a servo motor, an electric gripper, and an elastic element, used to clamp and adjust the position of the connector placement seat.

[0013] Furthermore, the hole positioning component includes:

[0014] A horizontally positioned electric slide table, the output end of which is connected to a short-stroke telescopic cylinder mounting base;

[0015] The short-stroke telescopic cylinder is fixed to the short-stroke telescopic cylinder mounting base, and its output end is connected to the servo motor mounting base;

[0016] The servo motor is fixed to the servo motor mounting base, and the output shaft is connected to the electric gripper mounting base;

[0017] The electric gripper is fixed to the electric gripper mounting base, and an elastic element is provided between the grippers to buffer the clamping force.

[0018] Furthermore, the elastic element includes: a telescopic rod, both ends of which are fixed to the inner side of the gripper of the electric gripper by pressure plates; and a pressure spring sleeved on the telescopic rod, located between the two pressure plates, for providing flexible pressure.

[0019] Furthermore, the sliding mating surface between the slide rail and the slider has a V-groove structure to enhance guiding stability; the diameter of the reduced diameter opening is smaller than the diameter of the electrical connector body.

[0020] Furthermore, the reset spring is a compression spring, with one end abutting against the slider and the other end abutting against the outer wall of the groove. Under normal conditions, it is in a pre-compressed state, providing the reset driving force.

[0021] Furthermore, the slider is composed of a first slider part and a second slider part, which are fixed by bolts.

[0022] Compared to existing technologies, this application uses a connector holder that can rotate on a slider. The movement and rotation are driven by the orifice positioning component, which can clamp different types of electrical connectors and ensure that the pins are coaxial with the sockets, thus achieving precise positioning. These improvements not only enhance assembly efficiency and yield, but also support the high-density connector requirements with complex radial layouts. Attached Figure Description

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0033] In the description of this application, it should be understood that the terms "upper," "lower," "front," "back," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the appendix. Figure 1 This description is provided for the convenience of describing this application and for the purpose of simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] like Figure 1-6 As shown, an electrical connector pin assembly includes: a rotary feeder 1, on which multiple sets of connector positioning components are distributed circumferentially.

[0035] The connector positioning assembly includes a slide rail 3, a slider 4, a guide rod 5, a return spring 6, and a connector placement seat 8;

[0036] The rotary feeder 1 is provided with a chute 2, with slide rails 3 fixed on both sides of the chute 2. The slider 4 slides with the slide rails 3 and can move linearly along the chute 2.

[0037] One end of the slider 4 is provided with a guide rod mounting hole 7, and the guide rod 5 is detachably connected to this end. A return spring 6 is sleeved on the outside of the guide rod 5 to push the slider 4 to return to its original position.

[0038] The connector holder 8 is rotatably connected to the slider 4. Its top is open to accommodate the electrical connector 10, and its bottom has a reduced diameter opening 9 to expose the socket 11 at the bottom of the electrical connector 10.

[0039] The slider 4 is composed of a first slider part 401 and a second slider part 402, and is fixed by a through bolt 12.

[0040] The rotary feeder 1 is equipped with a hole adjustment and positioning assembly, including an electric slide table 13, a short-stroke telescopic cylinder 15, a servo motor 17, an electric gripper 19 and an elastic element, which is used to clamp and adjust the position of the connector placement seat 8.

[0041] Specifically, the rotary feeder 1 is existing technology and will not be described in detail. The positioning components of the electrical connector 10 are circumferentially distributed to facilitate automated feeding. The electrical connector 10 is placed in the connector placement seat 8 with the socket 11 facing downwards. The connector placement seat 8 is connected to the slider 4 through a bearing to support the rotation of the connector placement seat 8. The connector placement seat 8 is clamped by the hole adjustment positioning component, and the hole adjustment positioning component can drive the connector placement seat 8 to move and rotate so that each socket 11 corresponds to the pin, which facilitates the insertion of the pin. When the slider 4 is driven to move by the hole adjustment positioning component, it simultaneously drives the guide rod 5 to move. The guide rod 5 can slide in the sliding hole. At the same time, the slider 4 compresses the return spring 6 so that the elasticity of the return spring 6 can push the slider 4 to return to its original position.

[0042] Furthermore, the hole positioning component includes:

[0043] A horizontally positioned electric slide 13 has its output end connected to a short-stroke telescopic cylinder mounting base 14.

[0044] The short-stroke telescopic cylinder 15 is fixed to the short-stroke telescopic cylinder mounting base 14, and its output end is connected to the servo motor mounting base 16.

[0045] The servo motor 17 is fixed to the servo motor mounting base 16, and the output shaft is connected to the electric gripper mounting base 18.

[0046] The electric gripper 19 is fixed to the electric gripper mounting base 18, and an elastic element is provided between its grippers to buffer the clamping force.

[0047] Furthermore, the elastic element includes: a telescopic rod 20, both ends of which are fixed to the inner side of the gripper of the electric gripper 19 via pressure plates 22; and a pressure spring 21 sleeved on the telescopic rod 20, located between the two pressure plates 22, for providing flexible pressure.

[0048] Specifically, when the electric gripper 19 is driven to descend, the elastic element first contacts the electrical connector 10 and presses against the electrical connector 10, securing the electrical connector 10 inside the connector placement seat 8, so that the electrical connector 10 can be rotated while the connector placement seat 8 is rotated.

[0049] Furthermore, the sliding mating surface between the slide rail 3 and the slider 4 is a V-groove structure to enhance guiding stability; the diameter of the reduced diameter port 9 is smaller than the diameter of the main body of the electrical connector 10 to prevent the electrical connector 10 from falling off.

[0050] Furthermore, the reset spring 6 is a compression spring, with one end abutting against the slider 4 and the other end abutting against the outer wall of the slide groove 2. Under normal conditions, it is in a pre-compressed state, providing reset driving force.

[0051] Furthermore, the slider 4 is composed of a first slider part 401 and a second slider part 402, which are fixed by bolts 12.

[0052] Specifically, the screw 12 can tighten 401 and 402 to allow for the removal and installation of the slider 4, and to allow for the replacement of different models of connector holders 8 to accommodate different models of electrical connectors 10.

[0053] In the above structure, the electrical connector 10 to be inserted is placed in the connector placement seat 8 with the socket 11 facing downwards. The rotation of the turntable feeder 1 feeds the electrical connectors 10 one by one to the area below the electric gripper 19. Then, the short-stroke telescopic cylinder 15 can drive the electric gripper 19 to rise and fall, and the electric slide table 13 can drive the electric gripper 19 to move horizontally. Through this interaction, the electric gripper 19 clamps the connector placement seat 8, while the elastic element presses against the electrical connector 10. The drive of the connector placement seat 8 drives the slider 4 to move. The interaction between the rotating and moving electrical connectors 10 and the visual system diagram (not shown) ensures that each socket... The pin insertion mechanism aligns with the connector placement mechanism, inserting the pin into the socket 11. The electric gripper 19 is driven to rotate by the servo motor 17, causing the connector placement seat 8 to rotate, which in turn causes the electrical connector 10 to rotate. Thus, the pin insertion mechanism can insert the pin into the socket 11 at different positions. At the same time, the electric slide table 13 drives the movement of the pin insertion mechanism to insert the pin into the socket 11 at different positions along the radial direction of the electrical connector 10. After the pin insertion is completed, the electric gripper 19 releases the connector placement seat 8. The return spring 6, which is pressed by the slider 4, pushes the slider 4 to reset, thus resetting the unloading and loading positions. Therefore, it can adapt to the radially distributed sockets 11.

Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this application.
