Description
Technical field
The utility model relates to a kind of communication cable plug, is specifically related to a kind of test plug for L29 type coaxial connector.
Background technology
Connector is alternatively referred to as connector assembly, it is widely used in various electric wiring, play a part to connect or disconnecting circuit, electric connector is in addition to meeting general performance requirement, the requirement of particular importance is that electric connector must reach contact well, reliable operation, easy to maintenance, whether its reliable operation directly affects the normal work of communication line.To this end, communication line has very strict requirement to the q&r of electric connector, also just because of the high-quality of electric connector and high reliability, it is made also to be widely used in the military systems such as Aeronautics and Astronautics, national defence.
At present, common L29 type connector, the effective contact surface of usual only one of which, and also this contact surface stress point is uneven, is easily deformed during use, slight deformation once occurs, and the PIM value of connector can be made to be deteriorated.Simultaneously, current L29 type connector is test when, there is no supporting test plug, if needing test, original-pack plug can only be used, because original-pack plug and socket be use threaded, so needing to twist frequently swivel nut and pine swivel nut test when, the most inconvenient and lose time.
Summary of the invention
For the deficiency overcoming prior art to exist, the utility model provides a kind of test plug for L29 type coaxial connector.
The utility model adopts the technical scheme that: a kind of test plug for L29 type coaxial connector, it includes plug outer conductor, coaxial cable for high frequency, center pin, plug insulator and fixed cover, a circle spring groove it is milled with in the inside of described fixed cover, the end of described spring groove is provided with elastic rubber ring, described center pin is positioned at plug outer conductor and its one end is connected with coaxial cable for high frequency, plug insulator is between plug outer conductor and coaxial cable for high frequency, medial end at plug outer conductor is provided with hole wall, and hole wall is enclosed in center pin surrounding.
Further, described fixed cover is divided into inner sleeve and overcoat by described spring groove, leaves gap and do not contact between the end of described inner sleeve with the end of described overcoat.The most described overcoat end is provided with square groove, and described elastic rubber ring is placed in square groove, and the outer wall of elastic rubber ring mutually extrudes with inner sleeve and overcoat respectively and contacts.
Further, a length of 4.3-4.5mm of described center pin, and its end is provided with chamfering.Described center pin uses nonmagnetic brass to make.
Further, described hole wall is provided with along central axial equally distributed notch.
Further, the material of described plug insulator is polytetrafluoroethylene (PTFE).
The beneficial effects of the utility model are: when testing L29 type coaxial connector, it is possible to achieve fast insert-pull, when socket is when testing, test plug connected and locking can be inserted directly into, without using screw thread and swivel nut to connect, save the plenty of time, also improve operating efficiency.It addition, this plug has outstanding electric property, can exchange completely with standard L29 type connector, and its PIM value is more stable.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the utility model with L29 type socket to inserting structure figure.
Fig. 3 is that the plug and socket of common L29 type coaxial connector is to inserting structure figure.
In figure: 1-plug outer conductor, 2-coaxial cable for high frequency, 3-center pin, 4-plug insulator, 5-fixed cover, 6-spring groove, 7-elastic rubber ring, 8-inner sleeve, 9-overcoat, 10-hole wall.
Detailed description of the invention
With specific embodiment, the utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of test plug for L29 type coaxial connector, it includes plug outer conductor 1, coaxial cable for high frequency 2, center pin 3, plug insulator 4 and fixed cover 5, it is milled with a circle spring groove 6 in the inside of described fixed cover 5, the end of described spring groove 6 is provided with elastic rubber ring 7, described center pin 3 is positioned at plug outer conductor 1 and its one end is connected with coaxial cable for high frequency 2, plug insulator 4 is between plug outer conductor 1 and coaxial cable for high frequency 2, medial end at plug outer conductor 1 is provided with hole wall 10, and hole wall 10 is enclosed in center pin 3 surrounding.
In the utility model, described fixed cover 5 is divided into inner sleeve 8 and overcoat 9 by described spring groove, leaves gap and do not contact between the end of described inner sleeve 8 with the end of described overcoat 9.Described overcoat 9 end is provided with square groove, and described elastic rubber ring 7 is placed in square groove, and the outer wall of elastic rubber ring 7 mutually extrudes with inner sleeve 8 and overcoat 9 respectively and contacts.It addition, a length of 4.3-4.5mm of described center pin 3, and its end is provided with chamfering；Center pin 3 uses nonmagnetic brass to make.Described hole wall 10 is provided with along central axial equally distributed notch；The material of described plug insulator 4 is polytetrafluoroethylene (PTFE).
As shown in Figures 2 and 3, common L29 type connector mainly with threaded, tests very inconvenient also ratio relatively time-consuming by contact at E after connecting, and if threaded dynamics is not in place, PIM value can be deteriorated.The utility model becomes L29 type and tests at the B of fast socket, connector and at C at the contact surface E L29 type connector, it is made to be changed to two effective contact surface B and C by an effective contact surface, dual guarantee has been accomplished for PIM value and conventional index, at additionally corresponding L29 type connector female end external screw thread contact head contact A, if in test to deviation or the most concentric occurs during inserting, this contact head can play centralizing function, ensure the connection that under any circumstance center conductor can be stable, test class product is more tightened up than normal product requirement longer on service life.In order to ensure the service life of contact head, at D, add elastic rubber ring make its service life longer so that it is PIM value is more preferable, more stable.After the utility model and normal L29 type screw thread coupling do various test Data Comparison, every test index does not has any difference, test convenient flexibly.This plug reaches about 40% when being connected to microwave communication and producing assembling and setting product in raising production efficiency, can substitute L29 type plug the most threaded during production test completely.
The utility model is not directed to part and the most same as the prior art prior art maybe can be used to be realized.
