As shown in Figure 1 to Figure 3, the connector that the utility model embodiment is provided, has the first of cloudy head to treat for connecting Connector (not shown) and the second part (not shown) to be connected with male, the connector include the outer conductor 10 and core of tubular Axle 20.The outer conductor 10 is set on the mandrel 20 and insulated between the mandrel 20 and is connected, and the mandrel 20 includes Cloudy head grafting with the described first part to be connected and the male portion 21 that is in the form of a column and inserted with the male of the described second part to be connected Connect and tubular cloudy head 22, the outer conductor 10 is including body 11, along the body 11 close to the male portion 21 End face axial extension the first plug division 12 and tubular shielding part 14, along the body 11 close to the cloudy head 22 End face axial extension the second plug division 13.Wherein, first plug division 12 is coaxially disposed and institute with the male portion 21 State the first plug division 12 and be located on the periphery of the male portion 21, second plug division 13 be coaxially disposed with the cloudy head 22 and The ring of second plug division 13 is located at the periphery of the cloudy head 22, the ring of shielding part 14 be located at first plug division 12 it is outer and It is set on the described first part to be connected.

The connector that the utility model is provided is shielded this by setting a shielding part 14 in the outer shroud of the first plug division 12 Portion 14 is set on the described first part to be connected, so that connector is for connecting footpath when the first connector and the second connector Strengthen to crystallized ability；Meanwhile, during plug-in connector, the shielding part 14 can also reduce non axial external force to connector Mandrel 20 influence, thus avoid mandrel 20 from being damaged or fracture, so as to ensure that the service life of connector.

It should be noted that in the utility model embodiment, first part to be connected and the second part to be connected are micro- Ripple communication field widely uses test cable, load or other connectors, the first part to be connected and the second part to be connected and this hair The size model number of bright described connector is adapted.In addition, the male and cloudy head are those skilled in the art's common technology Vocabulary, it is to be understood that male and cloudy head with identical size model number can generally be combined steady to be formed with inserting Fixed attachment structure.

The connector that the present embodiment is provided when in use, gets out the first part to be connected and the second part to be connected, the company of holding The shielding part 14 of device is connect, the first plug division 12 is directed at the first part to be connected so that described in the inserting of male portion 21 on connector The cloudy head of one part to be connected, and shielding part 14 is set on the described first part to be connected；Meanwhile, the second plug division 13 is aligned Second part to be connected is so that the male of the second part to be connected described in the inserting of cloudy head 22 on connector, is thus connected device by first Part to be connected and the second part to be connected are relatively firmly coupled to each other.Need the first part to be connected and the second part separation to be connected When, user can axially be extracted connector by shielding part 14 from the first connector and the second connector.

Further, as shown in Fig. 2 the shielding part 14 is provided with the first axially extending grooving 141 of multiple tracks.By setting Multiple first groovings 141 are put, one end of shielding part 14 will be made up of multiple flexure strips in aliform, and thus being shielded from portion 14 can be more preferable Ground is adapted to the first part to be connected.Standby spy is, for the first larger part to be connected of external diameter, to pass through the dilatating and deformable of shielding part 14, screen The first part to be connected can preferably be clamped by covering portion 14, so that the radial direction steadiness of connector is greatly enhanced.

Preferably, each first grooving 141 is uniformly distributed circumferentially on the shielding part 14, so that the edge of shielding part 14 The clamping force size for being radially applied to the first part to be connected is more uniform.

Preferably, the shielding part 14 is the cylindrical body that metal is made.The metallic shield portion 14 can preferably shield outer The interference of boundary's electromagnetic environment.In the present embodiment, shielding part 14 is made up of Cu alloy material.

Further, as shown in Figure 2 or Figure 3, connector also include being located in the outer conductor 10 and the mandrel 20 it Between insulator 30.The insulator 30 be used for shield outer conductor 10 and mandrel 20, with avoid outer conductor 10 and mandrel 20 it is mutual it Between there is signal interference.

Further, as shown in Fig. 2 first plug division 12 is provided with the second axially extending grooving 121 of multiple tracks.It is logical Cross and the second grooving of multiple tracks 121 is set on the first plug division 12, the first plug division 12 can be made preferably to clamp insulator 30.

Further, as shown in figure 3, the periphery of second plug division 13 is provided with the spiral shell being spirally connected with the described second part to be connected Line section 131.Second plug division 13 more can firmly be spun together with the second part to be connected, kept away by the thread segment 131 The situation for exempting to be easier to release when by axial force between connector and the second part to be connected occurs.

Preferably, as shown in Fig. 2 the male portion 21 is provided with least one the 3rd axially extending grooving 211.Pass through 3rd grooving 211 is set, and male portion 21 can produce certain elastic deformation in the cloudy head of the part to be connected of inserting first, go forward side by side And produce certain radial load to be preferably fixedly connected with the first part to be connected.In the present embodiment, only set in male portion 21 The 3rd grooving 211 together is put, to avoid male portion 21 from causing intensity decreases because fluting number is excessive.

Preferably, as shown in figure 3, the cloudy head 22 is provided with least one the 4th axially extending grooving 221.Pass through 4th grooving 221 is set, and cloudy head 22 can also produce certain radial load with more in the male of the part to be connected of inserting second It is fixedly connected with the second part to be connected well.In the present embodiment, the 3rd grooving 211 together is set only on cloudy head 22, to keep away Exempt from cloudy head 22 causes intensity decreases because fluting number is excessive.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model Any modifications, equivalent substitutions and improvements made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
