The present disclosure provides an electrical connector and a device for testing conduction which relate to the field of testing devices. By providing a first contact end having a planar structure, the contact area between the electrical connector and a testing substrate is increased, and a large current can be conducted and damage to the product and device is avoided. A second contact end is a point or linear structure, and when poor contact is caused due to the uneven testing substrate or oxidization of the testing substrate, effective contact and electrical connection with the testing substrate can be achieved, to improve the effectiveness of an electrical connection.

The present disclosure provides a terminal assembly, which comprises a first terminal component, a second terminal component, and an elastic member. The first terminal component comprises a first flat terminal, which comprises a cable connecting end part and a first contacting end part. The second terminal component is disposed on one side of the first terminal component. The second terminal component comprises a second flat terminal including a second contacting end part and an electrical connecting end part. The first contacting end part is contacting with the second contacting end part. Two ends of the elastic member are respectively connected to the first terminal component and the second terminal component. The second terminal component is able to move toward or move away with respect to the first terminal component through the elastic member. The first contacting end part is frictionally contacting with the second contacting end part.

A connector includes: a contact including a contact portion connected to a connection terminal by pushing the connection terminal of an external device; a protector protecting the contact portion by covering the contact and including a first opening portion making the contact portion protrude; and a base body accommodating the contact and the protector, and including a second opening portion making the protector protrude; a first waterproof elastic member provided between the contact and the first opening portion and preventing liquid from intruding from a space between the contact and the first opening portion; a second waterproof elastic member provided between the protector and the second opening portion and preventing liquid from intruding from a space between the protector and the second opening portion. The contact portion is movable with respect to the first opening portion. The protector is movable with respect to the second opening portion.

An electrical connector includes a base portion, a tail portion extending from a first side of the base portion, a serpentine portion having a first end connected to a second side of the base portion opposite to the first side, a movable head portion connected to a second end of the serpentine portion, and a housing in which an accommodation chamber is formed to accommodate the serpentine portion. The housing has a first end connected with the base portion and a second end provided with a limiting portion confining the serpentine portion within the accommodation chamber. The head portion is movable so as to pass through the limiting portion. The electrical connector is made of a single piece of metal.

An electrical contact is provided for connecting together substrates. The electrical contact has a longitudinal axis and includes first and second structures that are connected together to prevent relative movement between each other. The first structure extends along the longitudinal axis and has a rigid construction. The second structure includes a spring portion and a mounting portion. The spring portion is resiliently deflectable in the direction of the longitudinal axis. The mounting portion is adapted for securement to one of the substrates. A press-fit portion is provided that extends along the longitudinal axis and is adapted for press-fit insertion into a hole of the other one of the substrates. The press-fit portion may be part of the first structure or the second structure. In addition, the first structure may be composed of metal or plastic.

A test probe for use with a testing apparatus. The test probe includes a first portion, a second portion, and a third portion, with hinges between the first and second portions and the second and third portions. The first portion folded at the first hinge over the second portion, the third portion folded at the second hinge over the second portion, where the second portion is stacked between the first portion and the third portion. The test probe is compressible from a first uncompressed state to a second compressed state.

An electrical connector is adapted to be retained in a non-conducting housing and electrically connecting a first component to a second component spaced from one another. The connector includes a first end having a first contact portion for electrically communicating with the first component. A second end of the connector has a second contact portion for electrically communicating with the second component. The second end has a cantilevered beam adapted to flex at a knee portion to bias the second contact portion against an electrical contact surface of the second component. An attachment portion is disposed between the first and second ends. The attachment portion includes an engagement portion providing an interference fit with a mating groove of the housing in which the connector is retained.

A connection unit includes an insulating mounting frame and multiple resilient press-on contacts situated on the mounting frame. Each press-on contact includes a helical pressure spring that can exert an elastic force on a metal contact body. The contact body is connected in one piece to a connection plug or a connection socket. For each press-on contact, the mounting frame includes a hollow cylinder that forms a cavity within a circumferential wall, the cavity being closed off by a cover that is situated so as to be axially displaceable at the wall of the hollow cylinder. The pressure spring is situated inside the cavity, and with its elastic force acts on the cover. The contact body, in one piece, forms a contact disk that is situated on the outer side of the cover.

A connecting structure includes at least one conductive terminal having a body, a conducting portion connected below the body, a pre-breaking portion provided at an upper end of the body, and a temporary soldering portion connected above the pre-breaking portion; a first strip connected to the conducting portion; and a second strip soldered to the temporary soldering portion. A method for manufacturing an electrical connector includes: forming a first strip and at least one conductive terminal connected thereto; soldering a second strip to the temporary soldering portion of the conductive terminal; separating the conducting portion of the conductive terminal and the first strip; operating the second strip to control the conductive terminal to be mounted to a housing; and disconnecting the pre-breaking portion of the conductive terminal, and removing the second strip and the temporary soldering portion of the conductive terminal.

An electrical connector having a first connector part and a second connector part, the first connector part with at least one electrically conductive pin and the second connector part with at least one shuttle pin, the conductive pin having two or more electrically conductive cores, each conductive core being provided with an external electrical contact and an insulating material forming a watertight seal with the conductive core and the electrical contact. The conductive cores include two or more cores spaced from one another to form the conductive pin. Facing surfaces of the two or more cores are spaced by an air gap with insulating material in the air gap and overmoulded insulating material is in contact with other surfaces of the conductive cores.
