The latching elements latch a plurality of contact elements in the contact element receptacles. The second housing part has a locking section locking one of the latching elements in a latching position. The joint connector connects at least two of the contact elements.

A circuit element protection apparatus applied to a signal input terminal, the circuit element protection apparatus includes a slave processing unit, a main processing unit, a first soft start unit and a second soft start unit. The first soft start unit receives a signal from the signal input terminal, and is used for noise filtering on the signal and delayed a transmission of the signal to the slave processing unit. The second soft start unit receives the signal from the signal input terminal, and is used for noise filtering on the signal and delayed the transmission of the signal to the main processing unit. The present disclosure further includes a protection method for circuit elements.

In a structure in which a cable is installed into a connector is provided. A back retainer is arranged in a compressed state between an inner circumferential surface of a cylindrical portion, included in a connector body and extending in the axis line direction, and an outer circumferential surface of the cable. The back retainer includes a main annular portion which is configured such that a compression amount on the back retainer in the radial direction centered on the axis line direction gradually increases as the compression amount goes from one side toward the other side. The back retainer includes an engaging protrusion configured to prevent the back retainer from detaching from the cylindrical portion on an outer circumferential surface of the back retainer.

A connector includes a plurality of terminal receiving chambers arranged in parallel, a plurality of first tool insertion holes, and a plurality of second tool insertion holes. Each terminal receiving chamber is separated from an adjacent terminal receiving chamber by each of side walls disposed on both sides thereof. Each second tool insertion hole is formed to a side wall located at each of ends in a parallel direction of the terminal receiving chambers. In each second tool insertion hole, a lance unlock rib and a tool pressing rib are placed. The lance unlock rib is one of a pair of lance unlock ribs provided to a lance located at each of the ends in the parallel direction of the terminal receiving chambers. The tool pressing rib is provided to a side surface of the each second tool insertion hole, and protrudes in the each second tool insertion hole.

A connector includes a housing including a terminal accommodation chamber, a terminal fitting including a locking hole and to be inserted into the terminal accommodation chamber from behind the housing, and a locking lance for retaining the terminal fitting inserted into the terminal accommodation chamber. The locking lance is cantilevered forward and includes a body portion resiliently displaceable in a direction intersecting an insertion direction of the terminal fitting and a projection projecting from the body portion toward the terminal fitting and configured to enter the locking hole when the terminal fitting is inserted into the terminal accommodation chamber. A width of the projection is smaller than that of the locking hole. A maximum width of the body portion is larger than the width of the projection. A part of the body portion connected to the projection is formed with a guiding portion gradually reduced in width toward the projection.

A connector 10 is provided with a terminal 20 and a connector housing 40. The connector housing 40 includes a terminal accommodating portion 41 for accommodating the terminal 20 and a locking lance 50 for locking the terminal 20 accommodated in the terminal accommodating portion 41. A part of the terminal 20 around a terminal-side opening 28 is exposed through a second opening part 45 in a region including a locking projection 52 of the locking lance 50 when observed from front of the connector housing 40 along a front-rear direction. A front end of the locking lance 50 in the front-rear direction is located at the same position as or in front of that of the terminal 20 and located at the same position as or behind that of the terminal accommodating portion 41.

An electrical connector system includes a plug connector and a receptacle connector each of which having a plurality of terminal receiving cavities for receiving a plurality of terminal lead wires. The plug connector having a perimeter seal for creating a waterproof barrier between the plug connector and the receptacle connector. The receptacle connector including at least one bridging portion having a surface for guiding and aligning the seal when the plug and receptacle connectors are mated together.

A connector 10 is provided with a housing 20, a terminal fitting 30 to be accommodated into a cavity 21 of the housing 20, and a front portion 50 to be mounted on a front surface side of the housing 20. The front portion 50 includes a resilient portion 55 for pressing the terminal fitting 30 and sandwiching the terminal fitting 30 between a facing wall surface portion 21B of the cavity 21 and the resilient portion 55.

An electric connector includes a housing, at least one terminal, and at least two elastic members, the housing has at least one through hole, the at least one terminal is located at the at least one through hole and includes two arm parts, the at least two elastic members are clamped by the two arm parts and an inner wall forming the at least one through hole.

An electrical connector includes a housing that defines a cavity at a mating end. A terminal retention (TR) block is mounted to the housing within the cavity. The TR block defines multiple channels configured to receive contacts therein. The channels include deflectable retention latches configured to engage the contacts to retain the contacts in the channels. A terminal position assurance (TPA) clip is mounted to a distal end of the TR block within the cavity of the housing. The TPA clip is configured to block deflection of the retention latches to lock the contacts in the channels. The TPA clip has slots that align with the channels of the TR block and receive distal tips of the contacts therethrough. The slots have tapered lead-ins configured to guide the distal tips of the contacts from the channels into the slots.
