Description

Novel grooved crown spring jack contact

Technical Field

The utility model belongs to the technical field of hat spring jack contact element technique and specifically relates to a novel grooved hat spring jack contact element is related to.

Background

The crown spring is applied between the contact pin and the jack of the connector, the main function of the crown spring is to ensure the connection firmness of the contact pin and the jack, the crown belt type is a common one, and the middle part of the crown spring can be tightly attached to the contact pin to realize the connection of the contact pin and the jack when the contact pin is inserted into the crown spring during use. However, in the actual use process of these crown springs, because the crown spring is punched into the main body, the contact part between the crown spring and the main body is small, so that the contact position is easy to generate heat, and because the bending structure in the crown spring is generally fixedly arranged, only the crown spring with another specification can be selected when a large bending amount is needed, so that the use range of the crown spring is narrow.

SUMMERY OF THE UTILITY MODEL

In order to overcome not enough among the background art, the utility model discloses a novel grooved crown spring jack contact, the utility model discloses a large amount of connection structure fix the crown spring in the inside of main part, make area of contact between main part and the crown spring great from this to make the contact zone be difficult for generating heat, moreover can adjust the inside crooked volume of crown spring after installing according to the demand of using, enlarged the scope of using.

In order to realize the utility model aims at, the utility model adopts the following technical scheme:

the utility model provides a novel spring jack contact is hat to open slot type, includes main part and hat spring, the mounting hole has been seted up to the top of main part inside, screw one has been seted up to the bottom of mounting hole, fastening screw is installed to the bottom of hat spring, screw one and fastening screw threaded connection, the bottom position department that hat spring and fastening screw's hookup location department correspond the mounting hole sets up, the spread groove has been seted up on the top of hat spring and fastening screw's hookup location department.

The side face of the main body is provided with a second screw hole corresponding to the first screw hole, a clamping groove is formed in the fastening screw rod corresponding to the second screw hole, and the inner thread of the second screw hole is connected with a limiting screw rod.

The limiting screw is characterized in that pressing sheets which are uniformly distributed are arranged at two ends of the limiting screw, a sinking groove is formed in the position, corresponding to the pressing sheets, of the main body, and a straight-line-shaped groove is formed in the limiting screw inside the pressing sheets.

The outer portion of the top end ring of the crown spring is provided with an external thread area, and an internal thread area is arranged in the mounting hole.

Since the technical scheme is used, the utility model discloses following beneficial effect has:

a novel grooved crown spring jack contact, because crown spring and main part not only have great area of contact in the mounting hole inside, and the area of contact has also been great through being connected between fastening screw and the screw one, make the position of being connected between crown spring and the main part be difficult for generating heat when using, after crown spring installation, the user can rotate through the go-between to crown spring upper end, because the setting in external thread district and internal thread district, make the go-between after the downward rotation can not rise, can make the crooked volume grow of the inside card strip bending position department of crown spring under the effect of force, the application range of crown spring has been enlarged from this.

Detailed Description

The invention will be explained in more detail by the following examples, which disclose the invention and are intended to protect all technical improvements within the scope of the invention.

Combine attached figure 1~3 a novel grooved crown spring jack contact, including main part 1 and crown spring 4, mounting hole 2 has been seted up to the inside top of main part 1, screw 3 has been seted up to the bottom of mounting hole 2, fastening screw 5 is installed to the bottom of crown spring 4, screw 3 and fastening screw 5 threaded connection, the hookup location department of crown spring 4 and fastening screw 5 corresponds the bottom position department setting of mounting hole 2, spread groove 12 has been seted up on the top of the hookup location department of crown spring 4 and fastening screw 5, through the connection contact between screw 3 and fastening screw 5, has greatly increased the area of contact between crown spring 4 and the main part 1 from this for whole difficult heating in the use.

The side of the main body 1 is provided with a second screw hole 6 at a position corresponding to the first screw hole 3, the fastening screw rod 5 is provided with a clamping groove 7 at a position corresponding to the second screw hole 6, the inner thread of the second screw hole 6 is connected with a limit screw 8, the limit screw 8 passes through the position of the second screw hole 6 and passes through the position of the clamping groove 7, and the fastening screw rod 5 can be effectively prevented from rotating out of the inner part of the first screw hole 3.
