## Abstract

In order to improve the flexibility of one-piece quartz mounts, the section of the current lead pins that is pinched into a lug and projects beyond the bottom plate is reduced to a web between the bottom plate and the mounting section. The web is bent twice between the bottom plate and the mounting region so that there are formed a horizontal first web section and a second vertical section. The elasticity of the mounts are thereby further improved. The mounting section can be trimmed in the zone where the quartz disk is mounted.

## Claims

### Claim 1

A holder for a quartz resonator disk having opposed electrodes for energizing the disk, the holder comprising:
a pair of lugs passing through glass seals in a supporting base and being unitary with pins on an opposite of the supporting base, each lug being flattened on one side of the base to form a web divided into a first web section, a second web section and mounting section;
the first web sections starting at a location spaced from the glass seals and extending in opposite directions, the first web sections being of a first reduced width;
the second web sections extending parallel to one another and being joined to the first web sections by bends, the second web sections having the same widths as the first web sections; and
the mounting sections extending from the second web sections, the mounting sections having second widths greater than the widths of the first and second web sections and the mounting sections each having longitudinal slots for receiving edges of the quartz resonator disk and contacting the electrodes thereon.

### Claim 2 (depends on 1)

A holder according to claim 1, wherein in that the web sections each have a width equal to twice its thickness.

### Claim 3 (depends on 1)

A holder according to claim 1, wherein the lugs each have at least one punched-out portion for the formation of the webs.

### Claim 4 (depends on 3)

A holder according to claim 3, wherein the lugs include two symmetrical punched-out portions.

### Claim 5 (depends on 4)

A holder according to claim 4, wherein the webs are angled between the base and the mounting sections.

### Claim 6 (depends on 1)

A holder of claim 1, wherein the flattened sections of the lugs extending from the first web sections and into the glass seals have a width greater than the first sections.

### Claim 7 (depends on 1)

A holder according to claim 1, wherein the first web sections are shorter than the second web sections.

### Claim 8 (depends on 7)

A holder according to claim 7, wherein the lugs are laterally trimmed in the region of the mounting sections.

### Claim 9 (depends on 1)

A holder according to claim 1, wherein the webs are angled between the base and the mounting sections.

### Claim 10 (depends on 1)

A holder according to claim 1, wherein the lugs are laterally trimmed in the region of the mounting sections.

### Claim 11 (depends on 6)

The holder of claim 6, wherein the second sections extend substantially perpendicular to the first sections.

### Claim 12 (depends on 1)

The holder of claim 1, wherein the width of the mounting sections are less than the flattened sections of the lug extending into the insulators.

### Claim 13 (depends on 1)

The holder of claim 1, wherein the quartz resonator has an axis perpendicular to the faces thereof and wherein the lugs are flattened to extend parallel with the direction of the axis.
