Description

Detecting detectors for coaxial connectors

The invention relates to a detector for detecting a coaxial connecting seat, in particular to an effective prevention of the impact of the probe, which can avoid the damage caused by the probe, and the detection of the utility model in the whole implementation. Innovative designer of detectors for coaxial connectors.

According to the electronic and electrical equipment, it is often seen that the coaxial connector and the coaxial connector are used as the connection transmission of the electronic signal. The coaxial connector and the coaxial connector are mainly composed of the casing terminal, the insulating bushing and the signal terminal. Inserting the signal terminal into the central shaft hole of the insulating bushing, and assembling the signal terminal together with the insulating bushing in the housing terminal to form a coaxial connector and a coaxial connecting seat respectively, so that the The coaxial connector is interposed with another corresponding coaxial connector to enable the electronic and electrical devices respectively connected to the coaxial connector and the coaxial connector to be in a conductive state.

The coaxial connector and the coaxial connector structure design can provide great convenience for the docking connection of two electronic and electrical equipment, but the coaxial connector may be inserted into the coaxial connector, which may be due to the production process. The influence of various factors causes the coaxial connector to be smoothly connected to the coaxial connector or to be loose after the connection, so that the coaxial connector needs to be designed the same as the coaxial connector after the completion of the fabrication. The plug-in connection test of the detector ensures the quality of the coaxial connector.

Among them, the detector with the same structural design as the coaxial connecting device, in terms of structural design, please refer to the "coaxial connector" No. I365579 published on June 1, 101, which can handle the loading and unloading of the opposite bearing with the outer conductor. The present invention is characterized in that: a housing having a cylindrical front end portion inserted into the outer conductor, and a diameter of the front end portion having a retractable structure; and a probe extending from the front end in a state insulated from the housing a sleeve having a cylindrical portion into which the housing is inserted; and an elastic body that generates a force on the housing and the sleeve when the opposite receiving seat is not installed to keep the front end portion protruding to the barrel a first state outside the shape portion; and a magnet, when the counterpart socket is mounted, generating a force on the casing and the sleeve such that at least a portion of the front end portion is received in the tubular portion, and The front end portion contacts the inner circumferential surface of the cylindrical portion to maintain the second state in which the diameter expansion of the distal end portion is restricted.

However, although the above-mentioned "coaxial connector" can achieve the intended effect of being tested for plugging and connecting with the coaxial connector, it is also found in its actual implementation that the plunger of the probe of the structure protrudes out of the housing. When the plug is connected to the coaxial connector for testing, if the probe has a positional displacement between the plunger and the coaxial connector, the plunger is easily impacted, and the plunger is as fine as a needle. The shape and the lower strength of the structure cause the plunger to be easily skewed or even broken after being impacted, which in turn makes the test result inaccurate, so that there is still room for improvement in the overall structural design.
