Abstract

The utility model relates to a circuit connector fixed knot of storage formula energy spectrum gamma logging instrument constructs, makes a spacing step in the position that the corresponding spring of shell inner wall contacted with circuit sheath terminal surface, spacing step is used for the restriction circuit sheath to remove to the spring direction. When the logging instrument pumps out, the spring is compressed due to the inertia force, and after the spring is compressed, the circuit sheath is directly propped against the position of the limit step additionally arranged in the shell, so that the phenomenon that the circuit module is separated from the electronic component is avoided.

Description

Circuit connector fixing structure of storage type energy spectrum gamma logging instrument

Technical Field

The utility model belongs to logging instrument field relates to storage formula energy spectrum gamma logging instrument, especially a circuit connector fixed knot of storage formula energy spectrum gamma logging instrument constructs.

Background

A circuit connector fixing structure of a storage type energy spectrum gamma logging instrument in the prior art is shown in figures 1 and 2, a spring 2 compresses a circuit sheath 3 and a circuit module 4, so that the circuit module 4 is tightly inserted with a pin on an electronic component 6 to connect a circuit. Because the storage logging instrument has very big impact inertia when pumping out, the inertia force is left, can make circuit module 3 and electronic components 6 overcome spring pressure and separate, makes the circuit can not normally put through. Because the magnitude of the inertia force can be adjusted according to the actual situation when logging, the problem cannot be solved by simply increasing the force of the spring.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to overcome prior art's weak point, provide a circuit connector fixed knot of storage formula energy spectrum gamma logging instrument constructs, can avoid appearing circuit module and electronic components off-going phenomenon.

The utility model provides a technical scheme that technical problem adopted is:

a circuit connector fixing structure of a storage type energy spectrum gamma logging instrument is characterized in that a limiting step is formed in the position, corresponding to the contact position of a spring and the end face of a circuit sheath, of the inner wall of a shell, and the limiting step is used for limiting the circuit sheath to move towards the spring direction.

And the spring and the circuit sheath are coaxially arranged in the shell in a penetrating way in sequence, the circuit module is coaxially arranged in the circuit sheath in a penetrating way, and the circuit module is spliced with the electronic component with the contact pin.

And the electronic component with the contact pin is sleeved with a component protective sleeve, and the component protective sleeve is butted with the shell and connected with the shell through a screw.

The utility model has the advantages that:

the utility model discloses a spacing step is made in the position that corresponds spring and circuit sheath end face contact in the shell inner wall. When the logging instrument pumps out, the spring is compressed due to the inertia force, and after the spring is compressed, the circuit sheath is directly propped against the position of the limit step additionally arranged in the shell, so that the phenomenon that the circuit module is separated from the electronic component is avoided.

In the figure: the device comprises a shell 1, a spring 2, a circuit sheath 3, a circuit module 4, a component sheath 5 and an electronic component 6 (with a contact pin).

Detailed Description

The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.

A circuit connector fixing structure of a storage type energy spectrum gamma logging instrument comprises a shell 1, wherein a limiting step 7 is formed on the inner wall of the shell corresponding to the contact position of a spring 2 and the end face of a circuit sheath 3. The limiting step can limit the circuit sheath to move towards the spring direction.

When the logging instrument pumps out, the spring is compressed due to the inertia force, and after the spring is compressed by about 1mm, the circuit sheath 3 is directly propped against the newly added limit step 7 in the shell 1, so that the phenomenon that the circuit module 4 is separated from the electronic component 6 is avoided. The length of the pin is about 15mm, much greater than 1 mm.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the spirit of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
