[0003] The PCB board-mounted antenna includes an IPEX connector, a signal line, and a circuit board. In the existing detection process of FPC antennas, it is necessary to manually dock the IPEX connector with the detection head of the network analyzer. Due to the extremely small size of the IPEX connector, it is difficult for the operator to clearly see the insertion position and state, and it is difficult to accurately control the magnitude and direction of the force, which greatly increases the difficulty of docking the IPEX with the detection head, thereby affecting the detection efficiency, and even damaging the connector during docking.

[0004] Therefore, it is necessary to improve the detection device in the prior art. Content of the Utility Model

Detailed implementation manners

[0028] The following combines the accompanying drawings and embodiments to further describe the detailed implementation manners of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0029] "Top surface", "bottom", and "bottom surface" are referenced based on the normal use state of the detection device, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0030] As Figures 1-5 shown, a high-frequency PCB board-mounted antenna performance detection device includes a base 2, on the top surface of which a notch 204 is vertically opened, and an inner support part 205 of the groove is arranged on the inner side wall of the notch 204; a positioning block 3, which is slidably matched with the notch 204, and a joint positioning through groove 302 distributed vertically is opened on the side surface thereof, and the inner support part 205 of the groove is slidably matched with the joint positioning through groove 302; a return spring 301, which is arranged inside the notch 204, and its two ends are respectively connected to the bottom wall of the notch 204 and the positioning block 3; a detection head 4, which is arranged directly above the positioning block 3, the detection head 4 is connected with a lifting mechanism 5 and is driven to lift by the lifting mechanism 5; a signal line positioning groove 203, which is opened on the top surface of the base 2, and its extending direction coincides with the notch orientation of the joint positioning through groove 302.

[0031] The above detection device is applicable to the performance detection of antennas with IPEX connectors. The detection head 4 is connected to a network analyzer. The detection end of the detection head 4 can be adapted to the IPEX connector. After the detection head 4 is docked with the IPEX connector of the antenna body 6, various performances of the antenna body 6 can be detected and evaluated through the network analyzer, so as to remove defective products in the antenna body 6.

[0032] When the detection device is in use, the connector of the antenna body 6 is inserted into the inside of the connector positioning through groove 302, so that the connector of the antenna body 6 abuts against the inner wall of the connector positioning through groove 302. The shape of the connector positioning through groove 302 is adapted to the connector of the antenna body 6, so as to position the connector of the antenna body 6 through the connector positioning through groove 302; then the signal line of the antenna body 6 is clamped into the inside of the signal line positioning groove 203, and the signal line of the antenna body 6 is positioned through the signal line positioning groove 203. In this way, when the operator's hand releases the antenna body 6, the antenna body 6 will not slip, greatly improving the positioning accuracy; then the lifting mechanism 5 drives the detection head 4 to descend. When the detection head 4 contacts the positioning block 3, the detection end of the detection head 4 is located inside the connector positioning through groove 302. Subsequently, the detection head 4 continues to descend, and the positioning block 3 is pushed into the notch 204 through the detection head 4. During this process, the connector of the antenna body 6 slides inside the connector positioning through groove 302 until the connector of the antenna body 6 is docked with the detection end of the detection head 4. Then, the network analyzer detects the performance of the antenna body 6, so as to remove defective products in the antenna body 6; after the detection is completed, the detection head 4 rises and resets. At this time, the connector of the antenna body 6 and the detection head 4 can be separated manually. After separation, the antenna body 6 can be directly taken away. While the detection head 4 is rising, the pressure of the detection head 4 on the positioning block 3 decreases, and then the return spring 301 pushes the positioning block 3 to rise and reset. It should be noted that when the return spring 301 returns to the normal state, it is not enough to push the positioning block 3 out of the notch 204; the setting of the in-groove support portion 205 is used to support the connector portion of the antenna body 6 to prevent the connector 6 of the antenna body 6 from being driven downward by the positioning block 3, which affects the docking between the connector and the detection head 4.

[0033] In this detection device, the connector positioning through groove 302 and the signal line positioning through groove 203 position the antenna body 6 at the same time, which can improve the stability of the positioning of the antenna body 6, prevent the antenna body 6 from displacing during the docking process, and the positioned antenna body 6 can be accurately docked with the detection head 4. Compared with the manual docking method, the docking difficulty is greatly reduced, the docking accuracy is improved, the detection efficiency is improved, and the probability of damage to the antenna body 6 during docking is reduced.

[0034] A further improvement is that, as Figure 3 and 4As shown, an adhesion layer is provided on the bottom wall of the signal line positioning groove 203. The adhesion layer can be double-sided tape, which is convenient for replacement after the adhesion layer fails. Moreover, the connection strength of the double-sided tape is also beneficial for manually removing the antenna body 6 from the inside of the signal line positioning groove 203 after the detection is completed. Through the adhesion layer, the firmness of the connection between the signal line part of the antenna body 6 and the signal line positioning groove 203 can be improved, thereby preventing the antenna body 6 from shifting again after positioning is completed to ensure the detection accuracy. And when the pulling force of the adhesion layer on the antenna body 6 is greater than the acting force between the antenna body 6 and the detection head 4, the antenna body 6 can be automatically separated from the detection head 4 when the detection head 4 rises and resets, improving the convenience of equipment use.

[0035] A further improvement is that, as Figure 5 shown, the slot width of the joint positioning through groove 302 gradually increases from the bottom of the groove to the notch of the groove. In this way, a guiding inclined surface can be formed at the notch of the joint positioning through groove 302. During the insertion of the joint of the antenna body 6, the guiding inclined surface can guide the joint of the antenna body 6, facilitating the joint of the antenna body 6 to enter the inside of the joint positioning through groove 302, thereby improving the convenience of equipment use.

[0036] A further improvement is that, as Figure 3 and 6 shown, the positioning block 3 is hermetically connected to the notch 204, and the in-slot support portion 205 is hermetically connected to the joint positioning through groove 302, so that a sealed chamber is formed inside the notch 204. A blowing channel 303 communicating with the sealed chamber is provided at the bottom of the interface positioning groove. In the above detection device, the elastic force of the return spring 301 is sufficient to push the positioning block 3 to rise and reset. When the positioning block 3 moves up and down along the notch 204, the air inside the sealed chamber will flow in the blowing channel 303 and form an air flow inside the joint positioning through groove 302. In this way, the inside of the joint positioning through groove 302 and the joints of the detection head 4 and the antenna body 6 can be simply dusted through the air flow, thereby improving the stability of signal transmission and the detection accuracy.

[0037] A further improvement is that, as Figure 1As shown, a sliding base 1 is slidably connected to the bottom surface of the base 2 along the width direction of the base 2 itself. The number of notches 204 is multiple and they are arranged at equal intervals along the width direction of the base 2. A positioning block 3 is arranged in each notch 204, and the lifting mechanism 5 is fixedly connected to the sliding base 1. In the above detection device, a plurality of corresponding positioning blocks 3 and signal line positioning grooves 203 are arranged on the base 2, and a plurality of antenna bodies 6 can be fixed on the base 2 and positioned at the same time. Then, by pushing the base 2 to move on the sliding base 1, the detection head 4 can be respectively docked with the plurality of antenna bodies 6 fixed on the base 2 to achieve detection. In this way, a plurality of fixing stations for the antenna bodies 6 are formed on the base 2. When the antenna body 6 at one station is being detected, the antenna bodies 6 at other stations can be taken and placed, saving the time of waiting for the detection to be completed in the middle and further improving the detection efficiency.

[0038] A further improvement is that, as Figure 2 and 3 shown, a guiding groove 201 is formed in the bottom surface of the base 2 along the width direction of the base 2 itself, and a guide rail 101 is arranged on the top surface of the sliding base 1. The guide rail 101 is in sliding fit with the guiding groove 201. The cooperation between the guiding groove 201 and the guide rail 101 realizes the guiding effect on the sliding direction of the base 2, preventing the base 2 from moving out of position and further ensuring the accuracy of the detection device for detecting the antenna body 6.

[0039] A further improvement is that, as Figures 1-4 shown, a plurality of positioning holes 202 are arranged in the side surface of the base 2 along the width direction of the base 2 itself. Each positioning hole 202 corresponds to a notch 204 one by one. The sliding base 1 is fixedly connected with a threaded sleeve 102, and a bolt 103 is threadedly connected to the threaded sleeve 102. The bolt 103 is inserted and matched with one of the positioning holes 202. The position of the positioning hole 202 corresponds to the position of the positioning block 3. When the bolt 103 is docked with one of the positioning holes 202, the positioning block 3 corresponding to the positioning hole 202 is exactly under the detection head 4, enabling the antenna body 6 to be accurately docked with the detection head 4. In this way, through the docking between the bolt 103 and different positioning holes 202, the accurate docking of the relative positions between the antenna body 6 and the detection head 4 is realized, and the relative sliding between the base 2 and the sliding base 1 during detection can be prevented, thereby ensuring the docking accuracy between the antenna body 6 and the detection head 4 and improving the convenience of using the detection device.

[0040] A further improvement is that, as Figure 1 and 2As shown in the figure, the lifting mechanism 5 includes a slide bar 501 vertically and fixedly connected to the sliding base 1. A lifting seat 503 is slidably connected to the slide bar 501. The detection head 4 is detachably connected to the lifting seat 503. The slide bar 501 is further provided with a driving unit 502, and the driving unit 502 is in transmission connection with the lifting seat 503. The driving unit 502 includes a motor and a screw rod driven by the motor to rotate. The screw rod is threadedly connected to the lifting seat 503. When the screw rod rotates, it can drive the lifting seat 503 to slide along the slide bar 501, thereby driving the detection head 4 to lift, realizing the docking, detection and separation between the detection head 4 and the antenna body 6, and improving the detection efficiency of the detection device.
