Description

Tool is tightly tied the connector construction of usefulness

Technical field

The utility model is tightly tied the connector construction of usefulness about a kind of tool, mainly is the connector that is applied to electric power or electronic signal transmission, uses to improve its contact engaging and separating force and prevent to get loose, and has the usefulness of urgent waterproof concurrently.

Background technology

The transmission of electric power or electronic signal, all be as connection by connector, general connector comprises a male end that is provided with second terminal, has the female end of answering connecting terminal with another, the butt joint of its male and female end, the most substantially, to reach good being electrically connected outside the characteristic, (press, bad being electrically connected can the generation impedance cause decay or distortion, for electric power transfer, more can cause damaging because of this impedance increases generate heat) further to possess the excellent waterproof characteristic, certain requirement that its anti-water coefficient is all arranged in different plants or indoor and outdoor; Moreover, the combination of the male and female end of connector, still need possess certain for stress, in order to avoid get loose when involving.

For reaching above-mentioned purpose usefulness, habitual connector construction such as the novel M344614 patent of TaiWan, China case, it is mainly the anti-pull connector of a kind of tool, comprises: a glue core has at least one buckle; At least one terminal, one end are arranged in this glue core; One terminal fixing pedestal has at least one draw-in groove, and the other end of this terminal is arranged in this terminal fixing pedestal, and this draw-in groove of this terminal fixing pedestal and this buckle of this glue core are interlocked; And a housing holder, be located at this glue core, and prop up this draw-in groove and this buckle place that is interlocked.

By above-mentioned feature, glue core and terminal fixing pedestal are utilized the snap fastener engaging, when housing holder and housing are sealed then, will prop up snap fastener, to increase connector intensity and to prevent to get loose.But, this M344614 patent case, its structure complexity height, and for providing draw-in groove and buckle to be interlocked, and the housing holder props up this draw-in groove and the buckle place that is interlocked, its each combination of components, needing to keep a bonding gap nargin, is to cause its waterproof effect not good therefore.

In addition in the novel M327107 patent of TaiWan, China case, be to disclose a kind of water-tight connector composite set, comprise: a jack assemblies, comprise: a socket, this socket has an outward extending outer double-screw bolt, and the outer peripheral edges of double-screw bolt one end have a bulge loop outside this, and this bulge loop inner edge surface then has a block end; One waterproof ring is sheathed on this outer double-screw bolt; One nut is spirally connected mutually with this outer double-screw bolt; One plug-assembly interconnects with this jack assemblies, comprising: a plug, corresponding grafting with this socket; One knob, in order to be coated on this plug outside, this knob is tubular, on the outer peripheral edges of this knob, establish a breach, this knob can rotate with respect to this plug, and this knob has a fastening end to a end that should socket, in order to affixed mutually with the block end of this socket; And a waterproof washer, be located at this socket inside, and pulled between this socket and plug by folder.

By this, knob is extended into a tubular,, reach water-proof function, simultaneously on the outer ring surface of knob, offer a breach, make knob coat plug, have rotary action and be spirally connected mutually with this socket to coat this plug.

In above-mentioned patent case, main mat plug and socket is corresponding pegs graft, and coats the plug outside by knob, and then rotates relative to plug, and the block end of respective socket is affixed mutually; Same, in this M327107 case, for knob can be provided, its plug, socket combination need retention knob nargin free to rotate, therefore still have to get loose and the not good problem of waterproof performance.
