Description

Rotary connector

Technical field

The utility model relates to the device of electrical signal transfer between a kind of parts that are used for relative motion.

Background technology

Geophone is a kind of seismic wave receiving system that is used for oil seismic exploration.It is divided into land inspection wave detector and water is examined two kinds in wave detector.Since the operation principle difference of two kinds of wave detectors, the different in kind of reception seismic wave.At present, in order farthest to keep significant wave, filtering influences the disturbing wave composition of data interpretation, thereby improves the seismic data interpretation precision, for oil exploration provides the high-quality well location, water is examined wave detector and the land inspection wave detector formation dual sensor that combines.Because the double transmission conductor of doing land inspection signal of gravitational equilibrium body, it produces relative motion with respect to land inspection cylindrical shell, in order to ensure the transmission of water inspection signal, existing dual sensor, its water inspection geophone signal imports land inspection upper cover injection molding body and is connected with outgoing cable outside land inspection wave detector cylindrical shell, one of two signal line in the land inspection wave detector cylindrical shell are connected on the gravitational equilibrium body, another be connected by gravitational equilibrium body rotating shaft axle center and with the contact of gravitational equilibrium body insulation on.Fix two electroconductive elastic sheets on the support of bearing, corresponding connection with rotating shaft and contact.Because the remittance position of cable relates to wire bonds, operations such as injection moulding are the weak links in the process of producing product, have reduced reliability of products, have strengthened difficulty of processing, complex manufacturing; The double transmission conductor of doing land inspection signal of gravitational equilibrium body makes it impact seismic signal with respect to parameters such as the dielectric constant between land inspection cylindrical shell, insulation resistance, electric capacity, has reduced the seismic signal quality.In order to solve an above-mentioned difficult problem, need a kind of revolving joint of design, water is examined geophone signal pass with outgoing cable in the land inspection wave detector cylindrical shell and be connected, and, many connecting line is not intertwined in relative motion, at present, does not also have the revolving joint that can meet the demands.

The utility model content

The utility model is in order to overcome weak point of the prior art, a kind of dual sensor that is applicable to be provided, and is simple in structure, can realize the rotary connector of electrical signal transfer between the parts of relative motion.

The utility model is achieved through the following technical solutions:

A kind of rotary connector is characterized in that, is made up of bearing, the support of bearing, double-sided PCB, conductive contact pin, contact pilotage support, and pad and concentric conducting slip ring are arranged respectively on the described double-sided PCB two sides; Described bearing fixing is in the dead eye of the support of bearing, and described double-sided PCB conducting slip ring outwards is fixed on a side of the support of bearing; Be provided with the bonding wire through hole with the corresponding position of pad on the described support of bearing, be provided with the holding wire that is connected with pad in the described hole; Be provided with the conductive contact pin hole with the corresponding position of conducting slip ring on the described contact pilotage support, be provided with conductive contact pin in the described conductive contact pin hole and be enclosed within spring on the conductive contact pin, described conductive contact pin one end protrudes the conductive contact pin hole and is connected with conducting slip ring elasticity, the other end is connected with stop nut, is connected with holding wire on the described stop nut.

Described contact pilotage support is the T type.

The utlity model has following technique effect:

Rotary connector of the present utility model is used for dual sensor, can realize the transmission of the signal of telecommunication between the parts of relative motion, the specification that can unify the diameter of axle and the upper and lower carriage and the bearing thereof at gravitational equilibrium body two ends, for contact assembly except former land inspection part, replace except the gap bridge cable, simplify the product packaging technology, improved reliability of products, helped the production of product.Because the no longer double transmission conductor of doing land inspection signal of gravitational equilibrium body makes it no longer impact seismic signal with respect to parameters such as the dielectric constant between land inspection cylindrical shell, insulation resistance, electric capacity, has improved the seismic signal quality.Owing to removed the gap bridge cable, the overall dimension of product has been reduced about 20%, prevent from the damage that causes in the use to help exploring construction operation.And rotary connector of the present utility model is simple in structure, and easy to use, cost is low.
