Description

射頻連接器廣泛應用於移動通訊、天線、天饋線中，且射頻連接器連接於線纜的端部，以用於信號的傳輸。RF connectors are widely used in mobile communications, antennas, and antenna feeders, and the RF connectors are connected to the ends of cables for signal transmission.

目前，射頻連接器包括外殼、絕緣子及插針。外殼套設於絕緣子、插針及緊固件外，絕緣子套設於插針的一端外，以使射頻連接器符合絕緣的要求。相關技術中，外殼的內壁具有臺階結構，絕緣子的外壁具有與臺階結構相匹配的凸起結構，絕緣子與外殼相配合時，凸起結構與臺階結構緊密接觸。在組裝射頻連接器時，先將插針與線纜的纜芯連接，然後將絕緣子套設在插針上，最後將外殼套設在絕緣子及插針外。At present, RF connectors include shells, insulators and pins. The shell is sleeved outside the insulator, the pin and the fastener, and the insulator is sleeved outside one end of the pin, so that the radio frequency connector meets the insulation requirements. In the related art, the inner wall of the housing has a stepped structure, the outer wall of the insulator has a raised structure matching the stepped structure, and when the insulator is matched with the housing, the raised structure is in close contact with the stepped structure. When assembling the RF connector, first connect the pins to the core of the cable, then cover the insulators on the pins, and finally cover the outer shells over the insulators and pins.

但是，由於絕緣子的凸起結構與外殼的臺階結構緊密接觸，導致在安裝外殼的過程中，外殼與絕緣子之間的摩擦力較大，不便於射頻連接器的組裝，並且，當絕緣子或外殼存在製造誤差時，較容易出現絕緣子與外殼無法裝配的情況，導致絕緣子或外殼的廢品率較高。However, due to the close contact between the raised structure of the insulator and the stepped structure of the housing, the frictional force between the housing and the insulator is relatively large during the process of installing the housing, which is inconvenient for the assembly of the RF connector, and when the insulator or housing exists In the case of manufacturing errors, it is more likely that the insulator and the casing cannot be assembled, resulting in a high rejection rate of the insulator or the casing.

The hole 211 and the second through hole 221 are used to realize the assembly of the front insulator 2 and the pin 1 . The cross-sectional dimension of the protruding portion 22 is smaller than that of the fixing portion 21 , so that the first side surface 213 of the fixing portion 21 has a free area that is not connected with the protruding portion 22 . In this embodiment, the cross-sectional dimension of the fixing portion 21 may be the maximum dimension or characteristic dimension of the outline of the fixing portion 21 , and the cross-sectional dimension of the raised portion 22 may be the maximum dimension or characteristic dimension of the outline of the raised portion 22 .

可選地，凸起部22位於第一側面213的中心位置處，使得固定部21的外邊緣均具有空閒區域。可選地，如圖4所示，固定部21呈圓板狀結構，凸起部22呈圓柱狀結構，且呈圓板狀的固定部21的軸線與呈圓柱狀的凸起部22的軸線重合。Optionally, the protruding portion 22 is located at the center of the first side surface 213 , so that the outer edges of the fixing portion 21 all have free areas.

上述主體外殼3套設於前絕緣子2及插針1外，且固定部21的外緣212抵接於主體外殼3的內壁，由於凸起部22的橫截面尺寸小於固定部21的橫截面尺寸，使得凸起部22的側壁與主體外殼3的內壁存在間隙。在一實施例中，固定部21的外緣212可以理解為固定部21沿周向的外邊緣，且本實施例中兩個結構的抵接指兩個結構相互接觸但不固定連接。通過固定部21的外緣212與主體外殼3的抵接，使得主體外殼3能夠通過固定部21固定插針1。上述後絕緣子4位於前絕緣子2的一側，線纜10抵接於後絕緣子4。The main body shell 3 is sleeved outside the front insulator 2 and the pin 1, and the outer edge 212 of the fixing portion 21 is in contact with the inner wall of the main body shell 3. Since the cross-sectional dimension of the protruding portion 22 is smaller than that of the fixing portion 21 The size is such that there is a gap between the side wall of the boss 22 and the inner wall of the main body casing 3 . In one embodiment, the outer edge 212 of the fixing portion 21 can be understood as the outer edge of the fixing portion 21 along the circumferential direction, and the abutment of the two structures in this embodiment means that the two structures are in contact with each other but are not fixedly connected.

The outer edge 212 of the fixed portion 21 is in contact with the inner wall of the main body housing 3 , and the raised portion 22 is not in contact with the main body housing 3 . The inner wall is in contact, and there is a gap between the protruding part 22 and the main body shell 3, so that only the outer edge 212 of the fixing part 21 is in contact with the main body shell 3 under the premise of ensuring the insulating function of the front insulator 2, which reduces the distance between the front insulator 2 and the main body shell 3. The frictional force between the inner walls of the main body shell 3 facilitates the assembly between the front insulator 2 and the main body shell 3, thereby facilitating the assembly of the RF connector, and the contact area between the front insulator 2 and the main body shell 3 is small, and the current insulator 2 or When there is a small manufacturing error in the main body shell 3, the main body part 21 or the main body shell 3 can be slightly deformed, so that the front insulator 2 and the main body shell 3 can still be assembled successfully, and then the front insulator 2 and the main body shell 3 can be reduced. scrap rate.

並且，通過固定部21橫截面積尺寸大於凸起部22橫截面積尺寸的設置，使得固定部21與凸起部22及主體外殼3之間存在鏤空空間，在組裝射頻連接器時，該鏤空空間能夠增加空氣補償，進而便於前絕緣子2的裝配。In addition, by setting the size of the cross-sectional area of the fixing portion 21 larger than the size of the cross-sectional area of the raised portion 22, there is a hollow space between the fixing portion 21, the raised portion 22 and the main body shell 3. When the RF connector is assembled, the hollow space is formed. The space can increase the air compensation, thereby facilitating the assembly of the front insulator 2 .

本實施例中，如圖6所示，第二通孔221的橫截面尺寸大於第一通孔211的橫截面尺寸，且如圖4所示，插針1包括接觸段11和連接段12，接觸段11卡抵於第一通孔211，連接段12卡抵於第二通孔221，以提高插針1與前絕緣子2固接的可靠性，還能夠阻止插針1沿自身軸向移動。In this embodiment, as shown in FIG. 6 , the cross-sectional dimension of the second through hole 221 is larger than that of the first through hole 211 , and as shown in FIG. 4 , the pin 1 includes a contact section 11 and a connection section 12 , The contact segment 11 is stuck against the first through hole 211, and the connecting segment 12 is stuck against the second through hole 221, so as to improve the reliability of the fixed connection between the pin 1 and the front insulator 2, and can also prevent the pin 1 from moving along its own axis. .
