Description

Cover assembly lock using cam.

The present invention relates to a cover assembly locking device using a cam, and more particularly, a cover plate of a plate spring material is installed on a cover assembly of a fuse tester, and the cover assembly is firmly closed by installing a cam on a corresponding housing assembly. And it relates to a cover assembly locking device using a cam configured to be locked.

Initial failure test of missile fuses usually includes wiring status check, safety status check, transmission output check, signal processing algorithm check, detonation output check, fuse function check, self-destructive check and variable voltage check.

The device for this test needs to be easily configured by non-experts to be suitable for practical military operation, as well as to be simple to install and to prevent safety accidents.

Therefore, in the development process of the fuse, in order to improve the reliability through countless iterative simulations, an optical system having a structure for quickly and safely simulating a transmitter / receiver that detects a target using a laser beam and generates an initiator signal can be quickly and safely simulated. A fuse tester was presented.

The optical fuse tester is provided with an optical unit having a transmission opening and a receiving opening corresponding to a laser beam transmitting and receiving unit of an optical fuse of the missile, respectively, formed on the outer circumferential surface of the housing assembly, and converting a laser signal transmitted to the optical unit into an electrical signal. A detector is installed, and the electrical signal converted by the photo detector is transferred to the PCB through a heat shrinkable resin tube and is configured to be processed by the PCB.

A cover assembly which can be opened and closed to insert and withdraw laser measurement equipment such as an optical fuse using a laser is installed on the upper part of the housing assembly of the fuse tester configured as described above so as to achieve the desired purpose.

The cover assembly has a first hinge member 16 installed on one side of the housing assembly 2, and a second hinge member 17 installed on one side of the cover assembly 3, as shown in partial cross-sectional view in FIG. 1. The first hinge member 16 and the second hinge member 17 are coupled to each other through the hinge shaft 18 to open and close the lid assembly 3 by an artificial force around the hinge shaft 18. Thus, laser measurement equipment such as optical fuses can be inserted and withdrawn.

In this case, the cover assembly 3 is easily opened and closed, and the handle 10 is installed on the other side of the cover assembly 3 so that the cover assembly 3 can be locked when closed. The locking jaw 13 is installed on the other side of the housing assembly 2 so that the locking end 11 formed at the end of the handle 10 is coupled to the locking jaw 13 in a hook shape so that the cover assembly 3 The lid assembly 3 is configured to be locked when the lid is closed.

Specifically, the locking end 11 is formed at one end of the cover assembly 3 on the other side, and the handle 10 is formed between the rear end of the locking end 11 and the other end of the cover assembly 3. The handle 10 having the elastic spring 14 installed on the flow portion 15 formed to be flowable is coupled to the flow through the rotary pin 12 so as to be movable, and the housing assembly corresponding to the locking end 11. On the other side of (2) the locking step 13 is installed.

Therefore, when the cover assembly 3 is opened and closed to insert and withdraw laser measurement equipment such as an optical fuse, an artificial force is applied to the handle 10 in the opening direction of the cover assembly 3. One end of the handle 10, that is, the locking end 11, may be flown to the other end of the cover assembly 3 with respect to the rotary pin 12. At this time, when the locking end 11 is separated from the locking step 13 and lifts the cover assembly 3 through the handle 10, the hinge shaft 18 on one side of the cover assembly 3 is centered. By opening the lid assembly 3 it is possible to achieve the desired purpose.

On the other hand, when the cover assembly 3 is closed, the cover assembly 3 falls by gravity and its own weight, so that the locking end 11 and the locking jaw 13 are in contact with the slope, and at this time, the weight and gravity As the locking end 11 of the handle 10 flows in the same direction as when the cover assembly 3 is opened, the locking jaw 13 and the locking end 11 are coupled to each other in a hook shape so that the cover assembly ( 3) can be closed.

In addition, the elastic spring 14 installed at the rear of the locking end 11 is elastically supporting the locking end 11 in the opposite direction in which the locking end 11 flows when the cover assembly 3 is opened or closed. The lid assembly 3 is configured to maintain a closed state, that is, a locked state, without artificially applying a force to the handle 10.

However, according to the opening, closing, and locking device of the cover assembly 3 of the conventional fuse tester 1 described above, the handle 10 is exposed to the outside, so that the locking end 11 of the handle 10 is inadvertently inadvertent. While the flow is separated from the locking step 13 and the locked state of the cover assembly 3 can be released, and also the firm closed state of the cover assembly 3 can not be maintained, the handle 10 The exposure has led to problems such as lack of appearance.

Therefore, the present invention is invented to solve the above problems, a locking plate of a plate spring material rotatable by an artificial force is installed inside the cover assembly of the fuse tester, and the first step with a step in the housing assembly corresponding thereto. When the cover assembly is formed with a cam, the end of the locking plate is grounded under the second ground part of the cam when the cover assembly is closed, thereby generating an elastic force so that the cover assembly can be more firmly closed and locked. It is an object of the present invention to provide a cover assembly locking device using a cam, which can have a beautiful appearance in appearance.
