Description

Floating connector

Technical Field

The invention relates to the technical field of connectors, in particular to a floating connector.

Background

The floating connector includes a first connector including a first insulating fixed housing, an insulating movable housing, and a first terminal, and the insulating movable housing is capable of floating with respect to the first insulating fixed housing so as to be capable of absorbing vibration. The second connector includes a second insulative fixing housing and a second terminal, and transmits current or signals through connection of the second terminal and the first terminal.

For example, chinese patent application No. CN200510006215.5 (publication No. CN100483860C) discloses a "floating connector", which includes: a fixed-side housing fixed to the substrate and having an inner space; a movable-side housing located in the internal space and provided with a receiving recess portion to be fitted with the plug connector on a side opposite to the substrate; a plurality of contacts held between the two housings. Here, the U-shaped flexible portion formed between the portion held by the fixed-side housing and the portion held by the movable-side housing in each contact extends to project toward the opposite side of the substrate between the movable-side housing and the fixed-side housing, and is located in a contact protection space formed inside a contact protection wall provided on the movable-side housing. The contact portion of each contact is disposed on the surface of the accommodation recess of the movable-side housing so as to be exposed. The invention can increase the allowable dislocation between the shells when the shell is jogged with the other connector compared with the traditional structure.

For another example, chinese patent application No. CN201210017291.6 (publication No. CN102623841B) discloses a "floating connector", which includes: a movable base having a housing recess; a fixed base for loading the movable base in a freely movable manner; and a connecting member. Wherein, the connecting part includes: a lead portion exposed from a lower surface of the fixed base; a contact portion located in the housing recess; and an intermediate portion connecting the lead portion and the contact portion, wherein the intermediate portion has a bent elastic portion that is elastically deformable. The movable base includes: a base; a central protrusion; and an outer limiting wall. The bending elastic part is elastically deformed in the accommodating space of the connecting part, so that the movable base can freely move relative to the fixed base; the bending elastic part abuts against the central protruding part or the outer limiting wall to limit the movable base from moving beyond the allowable moving range.

In the above patent, the first connector has two contact members (equivalent to the first terminals below) or two connection members (equivalent to the first terminals below), but each contact member or connection member has only one contact position when being engaged with the second connector, so that the two are electrically connected, and in a severe use environment, for example, the vibration frequency is very high, or after the first connector and the second connector are inserted and pulled out for many times, the electrical connection between the two at the contact position is easily affected, so that the first connector and the second connector are in poor contact, and the whole floating connector fails to function.
