Description
Technical field
A kind of closed type connector plug structure is the utility model is related to, more particularly to the L5 connectors of sensor field are inserted
Head, suitable for connecting cables to sensor, transmission signal.
Background technology
Connector is indispensable device in electronic equipment, and place is blocked in connection circuit, realizes the predetermined work(of circuit
Can, the various types of signal being primarily adapted for use between transmission equipment, it is generally divided into two kinds of forms of plug and socket, complete use.Evaluation connects
Connecing device quality mainly has three mechanical performance, electric property and environmental performance aspects.
Sensor field is divided into two kinds of L5 plugs and L5 sockets usually using a kind of L5 connectors.General L5 plugs are fixed
In cable end, L5 sockets are fixed on a sensor.
Conventional L5 plug insides set spring, in use, spring by the excessive screw-down torque effect of nut or by
Vibration, the impact of big magnitude and trigger failure, cause L5 plugs to be connected with sensor socket and release；During storage, the elastic force of spring
Nut is axially moveable, causes the contact pin in plug exposed outside, is vulnerable to external force and acts on and mutagens shape, damage, influence machine
Tool performance.
Conventional L5 plugs can directly influence the contact pin in plug without seal approach, external environment.Environmental performance can make
Contact pin by temperature, humidity, salt fog, mould, sand and dust, the factor such as drench with rain effect and aoxidize, corrode, influence the electricity such as contact resistance
Gas performance.
In actual use, L5 connector plugs had influence on because of self structure the mechanical performance of connector, electric property and
Environmental performance, it is unfavorable for the signal transmission of sensor, influences test, monitoring result, it is impossible to meet use demand.
Technological improvement of the utility model based on L5 connector plugs, using the method that sealing ring is set up in nut groove
Improve the sealing of L5 connector plugs and socket；Sealing encloses position-limiting action simultaneously, prevents nut from moving axially, contact pin is begun
Final position shields in the inner chamber of nut；Core insulator protrudes, when L5 connector plugs are connected with socket, insulator
First with female contact, and elastic deformation is produced, its elastic force reaction increases the coupling mechanism force between screw thread, prevented on screw thread
Release.
It is connector plug structure of the prior art as shown in legend therein referring to Fig. 1, the plug of prior art
Interior setting spring 40.The end face of insulator 22 of prior art is less than the end face of housing 25, and housing 25 uses screw thread with sleeve pipe 23
Connection, therefore for convenience of installing, the straight trough of location purposes is set in the end face of housing 25.Meanwhile the conventional end of socket insulator 33
Face is slightly below the end face of Socket casing 31.During installation, first contact pin 21 is inserted in the endoporus of jack 32, then tightening nut 26 is in socket
On housing 31.The end face of housing 25 and the end contact of Socket casing 31, make to form gap between insulator 22 and socket insulator 33.
Contact pin 21, the environment of jack 32 are connected by this gap and housing end face straight trough, thread pitch with external environment.Use
When, spring 40 is compressed by nut 26 and housing 25.Shaken when by the excessive screw-down torque effect of nut 26 or by big magnitude
When moving, impacting, easily trigger failure, cause the threaded connection of nut 26 and Socket casing 31 to release, connector is failed.Deposit
When putting, spring 40 extends, and nut 26 is moved to the other end of housing 25, causes contact pin 21 exposed outside, is vulnerable to external force effect
And mutagens shape, damage.
