A connector terminal includes a contact portion to be contacted with a counter connector terminal, a hold portion held in a connector housing, and a coupling portion coupling the contact portion and the hold portion, the coupling portion being configured as a rectangular tube with four bending portions and having a single continuous band portion from the contact portion to the hold portion by having notches staggered from the contact portion toward the hold portion, each of the notches including an oblique part that extends to cross over adjacent two of the four bending portions, the oblique part of an odd numbered notch being slanted in a direction from the contact portion toward the hold portion as approaching a tip from an entrance thereof, an even numbered notch being slanted in a direction from the hold portion toward the contact portion as approaching a tip from an entrance thereof.

A belt connector is provided. The belt connector is configured to electrically connect a conductor of an electrode belt to a male portion of a snap connector electrode connected to a biometric device. The belt connector includes a frame, a fastener, and an engaging member. The frame includes a receiving hole having radial flexibility. The receiving hole is configured to receive and fasten the frame to a protrusion of the male portion of the snap connector electrode. The fastener is configured to fasten the frame to a first end of the electrode belt. The engaging member is adjacent to the receiving hole and engages the conductor of the electrode belt by the conductor passing through the receiving hole. When the male portion of the snap connector electrode penetrates the receiving hole, the conductor is forced into contact with a lateral surface of the male portion of the snap connector electrode.

In electrocardiography (ECG) system, a patient cable connecting one or more electrodes to a processing device for processing ECG signals may include one or more electrode connectors mechanically keyed to respective electrodes and/or a device connector mechanically and/or electronically keyed to a cable connector of the processing device. In some embodiments, keying between the cable and electrode is achieved, for example, with an electrode including a hollow-post portion that defines a bore in conjunction with a post protruding from an arm of the electrode connector that is sized to fit within the bore.

A connection terminal includes a conductive terminal main body having a female connection body, and a contact member arranged to oppose an inner circumferential surface of the female connection body in one region of an internal space. A first bulging body and a second bulging body protruding from the inner circumferential surface and electrically connected to a male connection body by sandwiching the male connection body with the contact member are provided in the other region of the internal space. The second bulging body has a first guide portion guiding the male connection body while sliding the male connection body, and a second guide portion guiding the contact member while sliding the contact member. Each of the first and second guide portions is formed in a tapered shape.

An L-type inner terminal in which the increase of the impedance of a connecting portion can be suppressed, an L-type coaxial connector including the L-type inner terminal, and a method for producing the L-type coaxial connector are provided. In the L-type inner terminal, the main portion and the crimping portion are placed inside an L-shaped bent part of the connecting portion. The main portion and crimping portion, which have a low impedance, are proximal to the connecting portion, and therefore the increase of the impedance of the connecting portion can be suppressed by using the main portion and crimping portion, which are possessed by the L-type inner terminal itself.

A receptacle terminal for receipt of a mating terminal therein. The receptacle terminal includes a contact portion having a bottom wall and resilient arms which extend from either side of the bottom wall. The bottom wall has a raised portion with a first embossment position proximate a lead-in surface at a mating end of the contact portion. The bottom wall has a second embossment spaced from the first embossment, the first and second embossments providing additional strength and stability to the contact portion to prevent unwanted bending of the terminal. This provides a stable electrical connection while allowing for a lower insertion force of the mating terminal into the socket terminal.
