Description

Technical Field

[0001] The present application relates to the field of tooling technology, and in particular to a universal tooling for testing the plugging and unplugging force of connectors. Background Art

[0002] Connectors are essential components used to connect two active components or to connect active components to circuits. They transmit signals or power and provide a detachable interface for easy connection and disconnection. SMP and SSMP connectors are two types of ultra-miniature RF coaxial connectors that are widely used in modern electronic devices, particularly in applications requiring high-density mounting and high-frequency signal transmission.

[0003] To ensure connector plugging and unplugging performance meets requirements, connectors are typically tested for plugging and unplugging force before they are purchased and stored. Currently, this method typically involves mounting the connector on a plugging and unplugging force test fixture, which is fixedly connected to a digital push-pull force tester. When the connector is removed from the plugging and unplugging force tester, the push-pull force tester displays the connector's plugging and unplugging force.

[0004] However, existing insertion force test fixtures are typically only compatible with one connector model. Measuring the insertion and extraction force of different connector models requires switching to a different test fixture, which increases operational complexity. Furthermore, due to the typically small size of SMP and SSMP connectors, operators must use tweezers to attach these small connectors to the test fixture. This method is not only inefficient but also prone to errors. Utility Model Content

[0029] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0030] The embodiment of the present application discloses a universal tool for testing the plugging and pulling force of connectors.

[0031] A universal tool for testing connector insertion and extraction forces includes a mounting base 1, a placement assembly 2, and a push assembly 3. The mounting base 1 is fixedly mounted on the end of a force measuring rod of a push-pull force tester. Several different types of plug connectors 11 are provided on the end of the mounting base 1 facing away from the tester. The placement assembly 2 is removably mounted on the mounting base 1 and has a guide channel internally disposed therein. The push assembly 3 engages with the guide channel.

[0032] Before testing the insertion and extraction force of connector 4, first place connector 4 in the guide channel of placement assembly 2. Placement assembly 2 is then secured to mounting base 1, ensuring that the axis of the guide channel aligns with the axis of plug connector 11. Next, push assembly 3 is inserted into the guide channel of placement assembly 2, allowing connector 4 to be inserted into plug connector 11 under the guidance of the guide channel. Afterward, mounting base 1 is securely attached to the end of the force measuring rod of the push-pull force tester, allowing connector 4 to be mounted on plug connector 11, thereby improving the ease and accuracy of installing connector 4.

[0033] The mounting base 1 is generally columnar, and the plug connector 11 is provided with different models to facilitate the installation of various different models of connectors 4 to be tested, such as SMP connectors and SSMP connectors. In order to facilitate the connection of the SMP connector and the SSMP connector, the plug connector 11 is a KK connector. The SMP connector adopts a KK connector that is compatible with the SMP connector, and the SSMP connector adopts a KK connector that is compatible with the SSMP connector. In the present application, the KK connector is threadedly connected to the mounting base 1. At the same time, in order to facilitate the testing of the plug-in and pull-out force of the rectangular connector, the plug connector 11 can also be a lead pin fixed to the mounting base 1, and its function is consistent with that of the KK connector, and the rectangular connector is inserted on the lead pin. In the embodiment of the present application, the lead pin is provided with different models such as seven cores, nine cores, thirteen cores, fifteen cores and twenty-one cores, which can be adjusted according to actual needs to adapt to different models of rectangular connectors.

[0034] The placement assembly 2 includes a connecting ring 21 and guide rods 22. Two connecting rings 21 are provided, and the two connecting rings 21 are coaxially arranged. A plurality of guide rods 22 are provided. In the embodiment of the present application, four guide rods 22 are provided. The length direction of the four guide rods 22 is parallel to the axis of the connecting ring 21, and the four guide rods 22 are circumferentially distributed along the axis direction of the connecting ring 21. The space between the guide rods 22 forms a guide channel. The connecting ring 21 and the guide rods 22 are integrally formed. The connecting ring 21 positions the guide rods 22 and improves the stability between adjacent guide rods 22.

[0035] To facilitate alignment of the axis of the guide channel with the axis of the plug connector 11, a positioning rod 221 is fixedly mounted at the end of each guide rod 22. The mounting base 1 is provided with a plurality of positioning holes 12, evenly distributed circumferentially along the axis of the plug connector 11. In this embodiment, four positioning holes 12 are provided. When the placement assembly 2 is mounted on the mounting base 1, the positioning rods 221 engage with the positioning holes 12.

[0036] To reduce the resistance of the connector 4 to movement within the guide channel, the guide rods 22 are all round rods, and the connector 4 to be tested makes point contact with the guide rods 22, thereby reducing the resistance to movement of the connector 4 to be tested. The placement assembly 2 is provided in several different models to facilitate adaptation to different models of connectors 4 to be tested.

[0037] The push assembly 3 includes a push rod 31, a push cap 32, and a spring 33. The push cap 32 is located at one end of the push rod 31 and is provided with a slide groove 321, so that the push rod 31 and the push cap 32 are slidably engaged. A blocking plate is fixedly mounted on the outer wall of the push rod 31 near the push cap 32. The spring 33 is sleeved on the push rod 31, with one end of the spring 33 contacting the push cap 32, and the other end of the spring 33 contacting the blocking plate. The end of the push rod 31 away from the push cap 32 is plugged into the guide channel, and the end of the push rod 31 away from the push cap 32 contacts the connector 4 to be tested located inside the guide channel. The operator drives the push rod 31 to move within the guide channel by pressing the push cap 32, thereby pushing the connector 4 to be tested. While pushing the connector 4 to be tested, the spring 33 provides a buffer, reducing the possibility of damage to the connector 4 to be tested due to excessive force.

[0038] The connector to be tested 4 is generally provided with a protrusion at one end close to the push rod 31 , and the push rod 31 is provided with a placement groove at one end close to the protrusion. When the push rod 31 and the connector to be tested 4 collide, the protrusion is placed inside the placement groove for protection.

[0039] The implementation principle of a universal tooling for connector plugging and unplugging force testing according to an embodiment of the present application is as follows: the connector 4 to be tested is placed inside a guide channel, which positions the connector 4 to be tested. The positioning rod 221 on the guide rod 22 is then inserted into the positioning hole 12, so that the axis of the guide channel coincides with the axis of the plug connector 11. Next, a push rod 31 is placed inside the guide channel. The operator presses the cap 32 to cause the push rod 31 to push the connector 4 to be tested within the guide channel and insert the connector 4 to be tested into the plug connector 11. Finally, the mounting base 1 is fixed to the force measuring rod of the push-pull force tester, completing the placement of the connector 4 to be tested.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
