## Abstract

A connector terminal including a cable fixing unit connected to a signal transmission cable, an upper contact-pressing unit configured to extend in one direction from the cable fixing unit, and a lower contact-pressing unit configured to extend from the cable fixing unit in parallel to the upper contact-pressing unit with a predetermined gap from the upper contact-pressing unit. At least one of the upper contact-pressing unit and the lower contact-pressing unit is provided to be elastically movable to increase or decrease the gap.

## Claims

### Claim 1

A connector terminal, comprising:
a cable fixing unit configured to connect to a signal transmission cable;
an upper contact-pressing unit extending lengthwise in a first direction from the cable fixing unit; and
a lower contact-pressing unit extending lengthwise in the first direction parallel to the upper contact-pressing unit with a gap defining a distance between the upper contact-pressing unit and the lower contact-pressing unit in a second direction that is not parallel to the first direction,
wherein at least one of the upper contact-pressing unit or the lower contact-pressing unit is configured to be elastically movable to increase or decrease the gap, and
wherein the upper contact-pressing unit comprises:
a support part integrally formed with the cable fixing unit; and
an elastic displacing part connected to the support part by at least one elastic member, wherein the elastic member is configured to apply an elastic restoring force on the elastic displacing part in the second direction.

### Claim 2 (depends on 1)

The connector terminal according to claim 1,
wherein the lower contact-pressing unit is integrally formed with the cable fixing unit.

### Claim 3 (depends on 1)

The connector terminal according to claim 1,
wherein the support part has a coupling groove formed by depressing a surface thereof by a predetermined depth, wherein the surface faces the elastic displacing part, and
wherein the elastic member includes:
a block inserted into the coupling groove and protruding from the surface of the elastic displacing part; and
at least one spring interposed between the coupling groove and the block.

### Claim 4 (depends on 3)

The connector terminal according to claim 3,
wherein the at least one spring includes a plurality of springs arranged symmetrically at an upper surface and a lower surface of the block.

### Claim 5 (depends on 3)

The connector terminal according to claim 3,
wherein the at least one spring is either a leaf spring or a coil spring.

### Claim 6 (depends on 5)

The connector terminal according to claim 5,
wherein the at least one spring is a plurality of leaf springs positioned at predetermined intervals along a longitudinal direction of the block, wherein each leaf spring has a center portion fixed to the block, and ends extending from the center portion and separated by a predetermined width.

### Claim 7 (depends on 1)

The connector terminal according to claim 1,
wherein the constant distance between the support part and the lower contact-pressing unit is greater than a distance between the elastic displacing part when the elastic member is not moved and the lower contact-pressing unit.

### Claim 8 (depends on 1)

The connector terminal according to claim 1,
wherein the elastic displacing part includes one or more first guide protrusions, and wherein the lower contact-pressing unit includes one or more second guide protrusions, wherein the first and second guide protrusions protrude toward each other.

### Claim 9 (depends on 1)

A connector, which is directly mounted to a circuit board, comprising:
a connector terminal according to claim 1; and
a connector housing configured to accommodate the connector terminal and configured to be installed at an edge of the circuit board,
wherein the connector housing includes an upper plate and a lower plate including:
respective front portions spaced apart from each other so that the edge of the circuit board is capable of being inserted between the upper plate and lower plate to a predetermined depth; and
respective rear portions connected to each other to form a single body, and
wherein at least one of the upper plate and the lower plate includes a clamping part configured to clamp the circuit board in a second direction that is perpendicular to the first direction.

### Claim 10 (depends on 9)

The connector according to claim 9,
wherein a portion of the clamping part is fitted into the upper plate in the second direction, and the portion of the clamping part is shaped in a saw-tooth pattern inclined in one direction.

### Claim 11 (depends on 9)

The connector according to claim 9,
wherein the connector housing further includes holding ribs provided to respective opposing side surfaces of the connector housing, and
wherein each holding rib includes an approximately U-shaped terminal section into which the circuit board is capable of being fitted.

### Claim 12 (depends on 9)

The connector according to claim 9,
wherein the connector housing further includes a latch portion configured to be hooked to a fastening hole positioned in the circuit board in advance,
wherein the upper plate includes a first upper plate part and a second upper plate part, and
wherein the latch portion is a lever type including a hooking protrusion positioned at a first end thereof and configured to be hooked to and unhooked from the fastening hole so that the first end is lifted when an opposing second end is pressed down, and wherein the latch portion is positioned between the first upper plate part and the second upper plate part.

### Claim 13 (depends on 1)

The connector terminal according to claim 1, wherein the at least one elastic member includes at least one spring.

### Claim 14 (depends on 1)

The connector terminal according to claim 1, wherein each of the elastic displacing part and the at least one elastic member are configured to be at least partially inserted into a depressed surface of the support part.

### Claim 15 (depends on 1)

The connector terminal according to claim 1, wherein the elastic displacing part is integrally formed with the at least one elastic member.
