[0030] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present application.
[0031] The present application provides a test radio frequency connector. As shown in Figure 1 and Figure 2 In the present embodiment, the test radio frequency connector 10 includes a first outer conductor 111, a second outer conductor 112, a center pin 120, a sleeve 130, a fixing flange 140, a first elastic member 150, a second elastic member 160, a first insulating member 170 and a second insulating member 180. As shown in Figure 2 The lower end of the first outer conductor 111 is sleeved with the upper end of the second outer conductor 112, and the second outer conductor 112 can move axially relative to the first outer conductor 111. Specifically, the sleeving of the first outer conductor 111 and the second outer conductor 112 can be as shown in Figure 2The first outer conductor 111 is sleeved on the upper end of the second outer conductor 112, or the second outer conductor 112 is sleeved on the lower end of the first outer conductor 111, which is not limited herein.
[0032] The first elastic member 150 is sleeved on the outer side of the second outer conductor 112, the upper end of the first elastic member 150 abuts against the first outer conductor 111, and the lower end of the first elastic member 150 abuts against the second outer conductor 112. The second outer conductor 112 is arranged to be movable relative to the first outer conductor 111, and the first elastic member 150 is arranged between the second outer conductor 112 and the first outer conductor 111, so that the second outer conductor 112 is elastically connected with the first outer conductor 111. When the outer conductor 100 (including the first outer conductor 111 and the second outer conductor 112) contacts the measured connector, the outer conductor 100 can be elastically stretched and moved. The lower end of the first outer conductor 111 is sleeved with the upper end of the second outer conductor 112, and the sleeved part forms a support and a guide, avoiding deformation and dislocation of the elastic connection between the first outer conductor 111 and the second outer conductor 112 caused by the connection of the first elastic member 150.
[0033] With reference to Figure 2 , the center pin 120 is arranged inside the first outer conductor 111 and the second outer conductor 112, and is insulated from the first outer conductor 111 through the first insulating member and is insulated from the second outer conductor 112 through the second insulating member. As shown in Figure 2 , the two ends of the center pin 120 penetrate the first outer conductor 111 and the second outer conductor 112, so that the two ends of the center pin 120 can contact the center conductor of the measured connector 30. It can be understood that the first outer conductor 111 and the second outer conductor 112 are both provided with through holes for penetrating the center pin 120.
[0034] The sleeve 130 is sleeved on the outer side of the first outer conductor 111 and the second outer conductor 112. The sleeve 130 can fix and guide the first outer conductor 111 and the second outer conductor 112. At the same time, the sleeve 130 can protect the first elastic member 150 arranged between the first outer conductor 111 and the second outer conductor 112. The fixing flange 140 is sleeved on the upper end of the first outer conductor 111.
[0035] As shown in Figure 2As shown, the second elastic member 160 is arranged between the fixed flange 140 and the sleeve 130, the upper end of the second elastic member 160 abuts against the fixed flange 140, and the lower end of the second elastic member 160 abuts against the sleeve 130. By arranging the second elastic member 160 between the fixed flange 140 and the sleeve 130, the elastic force value of the center pin spring in the prior art test radio frequency connector is replaced, the center pin 120 does not need to be arranged as an elastic pogo pin structure, the contact of the self sliding fit of the center pin 120 is reduced, the contact points are reduced, and the contact is more stable, thereby reducing the false test rate. At the same time, the center pin 120 does not need to be arranged as a pogo pin structure, and the service life of the center pin 120 can be prolonged.
[0036] Reference Figure 2 As shown, the first elastic member 150 is conductive silica gel. The conductive silica gel is used as the first elastic member 150, which can not only ensure the elasticity of the first elastic member 150 to form an elastic connection between the second outer conductor 112 and the first outer conductor 111 through the first elastic member 150, but also can conduct electricity by using the conductive silica gel, and the conductive silica gel is used as part of the signal transmission of the outer conductor 110. Compared with the conventional test radio frequency connector in the prior art which uses a spring as the first elastic member 150, the use of conductive silica gel as the first elastic member 150 in the embodiment of the application can improve the contact effect. As shown in Figure 2 As shown, the conductive silica gel 150 closely adheres to the first outer conductor 111 and the second outer conductor 112, so that the entire outer conductor 110 has only one contact point with the measured connector 30, the contact points are fewer, the contact is more stable, and the false test rate is further reduced.
[0037] In an embodiment, as shown in Figure 2 As shown, the second elastic member 160 is a spring, and the spring is sleeved outside the first outer conductor 111. The spring is convenient to assemble and has low cost.
[0038] In an embodiment, as shown in Figure 2 and Figure 4 As shown, the end of the second outer conductor 112 abutting against the first elastic member 150 is provided with a fixed groove 1121. As shown in Figure 2 and Figure 4 As shown, the second outer conductor 112 includes an end face A opposite to the first outer conductor 111, the fixed groove 1121 extends downward along the axial direction from the end face A, and the conductive silica gel is inserted into the fixed groove 1121, so as to limit and fix the conductive silica gel. As shown in Figure 2 The arrangement of the fixed groove 1121 can also separate the conductive silica gel from the sleeve 130 by using the groove wall of the fixed groove 1121, so as to avoid the contact between the conductive silica gel and the sleeve 130 and increase the friction force.
[0039] As shown in Figure 4Further, as shown, the second outer conductor 112 includes a small-diameter portion 1122 and a large-diameter portion 1123. The diameter of the small-diameter portion 1122 is smaller than the diameter of the large-diameter portion 1123, and the small-diameter portion 1122 and the large-diameter portion 1123 are arranged in sequence along the axial direction. In combination with Figure 2 and Figure 4 As shown, the small-diameter portion 1122 is inserted into the first outer conductor 111, so that the second outer conductor 112 is sleeved with the first outer conductor 111, and the second outer conductor 112 can slide in the first outer conductor 111. As shown, Figure 4 As shown, the fixing groove 1121 is formed by extending the end face A of the large-diameter portion 1123 along the axial direction.
[0040] As shown, Figure 2 The outer side of the upper end of the first outer conductor 111 is provided with a first boss 1111, and the lower side of the first boss 1111 abuts against the fixing flange 140. Thus, the downward movement of the first outer conductor 111 is limited. At the same time, the upward movement of the first outer conductor 111 is not limited, as shown, Figure 6 As shown, when the test radio frequency connector 10 is installed to the external jig 20, the outer conductor 110 contacts the outer conductor 110 of the measured connector 30. As shown, Figure 6 The outer conductor 110 can be lifted upward by the outer conductor 110 of the measured connector 30. In the above structure, the first boss 1111 is arranged on the outer side of the upper end of the first outer conductor 111, and the lower side of the first boss 1111 abuts against the fixing flange 140. Thus, when the test radio frequency connector 10 contacts the measured connector 30, the outer conductor 110 has a space for upward movement, and the upward movement of the outer conductor 110 is not limited.
[0041] Further, as shown, Figure 3 The fixing flange 140 is provided with a through hole 141 for the first outer conductor 111 to pass through. The inner wall of the through hole 141 is provided with a second boss 142, and the second boss 142 abuts against the first boss 1111. Specifically, as shown, Figure 2 The upper side of the second boss 142 abuts against the lower side of the first boss 1111. The second boss 142 is arranged in the through hole 141 of the fixing flange 140 to abut against the first boss 1111 of the first outer conductor 111, so that the first boss 1111 can be hidden in the through hole 141, without protruding from the upper end face of the fixing flange 140, thereby maintaining the flatness of the flange end face.
[0042] Continuing to refer to Figure 2 The lower end of the sleeve 130 is provided with a third boss 131 extending inward. The second outer conductor 112 is provided with a limiting step 1124, and the upper side of the third boss 131 abuts against the limiting step 1124, thereby limiting the downward movement of the second outer conductor 112, and avoiding the second outer conductor 112 from being pulled out of the sleeve 130. Specifically, as shown,Figure 4 As shown, the limiting step 1124 is the lower end surface of the large diameter part 1123 of the sleeve 130.
[0043] In the embodiment of the present application, as shown in Figure 2 As shown, the center pin 120 is an integrated pin body. In the prior art, the center pin is a flexible pogo pin structure. In the embodiment of the present application, the second elastic member 160 is arranged between the fixing flange 140 and the sleeve 130 to replace the flexible pogo pin structure of the center pin in the prior art. Therefore, in the embodiment of the present application, the center pin 120 can be arranged as an integrated pin body. The integrated pin body has fewer contacts and more stable contact compared with the center pin contact of the flexible pogo pin structure. At the same time, the service life is longer.
[0044] In an embodiment, as shown in Figure 1 As shown, the fixing flange 140 is provided with mounting holes 143 on both sides, and the test radio frequency connector 10 is mounted on the external jig 20 through the mounting holes 143. As shown in Figure 6 As shown, the screw is passed through the mounting hole 143 and locked on the external jig 20.
