Abstract

The invention discloses a barb type quick locking connector, consisting of a plug and a socket, wherein the plug comprises a plug shell and a plug base; a pin contact piece is arranged inside the plug base; the plug base is arranged inside the plug shell, and is sealed by a plug pouring sealant; the socket comprises a socket shell and a socket base; a jack contact piece is arranged inside the socket base; and the socket base is arranged inside the socket shell and is sealed by a socket pouring sealant. The barb type quick locking connector is technically characterized in that grooves are arranged at the both sides of the plug base; locking sheets with a barb structure are respectively nested inside the grooves; kidney-shaped grooves matched with barbs of the locking sheets are formed in the socket shell; and rectangular windows corresponding to the locking sheets in shape and size are formed in the plug shell. The barb type quick locking connector provided by the invention has the advantages of smart locking structure, reliable locking effect and convenience in plugging, and can be improved and realized on the basis of appearance of a non-quick locking connector. The defect that the normal rapid locking connector has a large size can be overcome without increasing the appearance size of the connector. The barb type quick locking connector is beneficial to the microminiaturization development of the rapid locking connector.

Description

A kind of hangnail quick-lock connector

Technical field the invention belongs to technical field of electric connectors, relates to a kind of hangnail quick-lock connector.

The quick-lock connector that background technology is traditional, particularly rectangle quick-lock connector generally have following several: a kind of is that fast lock locking member is installed on the installing hole of connector, and this locking member structure is various, and coupling type is arranged, the elastic clip hair style; A kind of is in the connector side locking member to be installed, and has to install in both sides, has in independent one side to install, and structure also has the formula, flexure strip structure etc. of taking of hanging.No matter adopt which kind of locking mechanism, the common feature of these fast latch fittings is exactly that overall dimension is larger, this just causes quick-lock connector more much bigger than the overall dimension of non-quick-lock connector, and these quick-lock connectors can not be realized the microminiaturized development of connector, and its application is subject to certain restrictions.

Summary of the invention the objective of the invention is to solve prior art and has the large technical problem of quick-lock connector overall dimension, provides a kind of hangnail quick-lock connector, to overcome the deficiencies in the prior art.

Hangnail quick-lock connector of the present invention is comprised of plug and socket, and it comprises plug body and Plug base described plug, establishes contact pin contacting piece in the Plug base, and described Plug base is arranged in the plug body, is sealed by the plug casting glue; It comprises jack housing and socket base described socket, establishes jack contact in the socket base, and described socket base is arranged in the jack housing, is sealed by the socket casting glue; Its main points are that the both sides of described Plug base are provided with groove, and groove is embedded with the stay that is the hangnail structure; Described jack housing is provided with the kidney slot that matches with the hangnail of stay; Described plug body is provided with and stay shape, the corresponding rectangular window of size.

The plug two sides of quick-lock connector of the present invention are embedded with the stay of two hangnail structures, because stay for being inlaid in connector inside, does not take the connector space outerpace, do not increase the overall dimension of connector; The kidney slot that cooperates with the hangnail stay is arranged on the shell of socket, and when connector plug, socket docking, the hangnail of stay is hung and is ridden on the kidney slot of jack housing, thereby realizes the quick locking of connector.Because stay is the hangnail structure, be that the inclined-plane guiding of hangnail plugs together when plugging together, plug together easily; When connector separates, for hangnail right angle face cooperates with the rectangular aperture of socket, unless there is external force to promote stay, stay can not deviate from from the opening part of jack housing, thus reach the purpose of locking.When wanting release, the stay at manual squeezing jack housing place, the pulling plug gets final product release.

Locking mechanism exquisiteness of the present invention, reliable lock, plug are conveniently, can improve on the profile basis of non-quick-lock connector and realize, do not increase the overall dimension of connector, remedy the large defective of conventional quick-lock connector overall dimension, be beneficial to the microminiaturization development of quick-lock connector.

Among the figure: 1. plug body 2. staies 3. contact pin contacting pieces 4. Plug bases 5. plug casting glues 6 jack housing 7. jack contacts 8. socket base 9. socket casting glues

Embodiment is with reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6 and Fig. 7, hangnail quick-lock connector of the present invention, formed by plug and socket, it comprises described plug outside the plug, 1 and Plug base 4, establish contact pin contacting piece 3 in the Plug base 4, described Plug base 4 is arranged in the plug body 1, by 5 sealings of plug casting glue; It comprises jack housing 6 and socket base 8 described socket, establishes jack contact 7 in the socket base 8, and described socket base 8 is arranged in the jack housing 6, by 9 sealings of socket casting glue; The both sides of described Plug base 4 are provided with groove, and groove is embedded with the stay 2 that is the hangnail structure; Described jack housing 6 is provided with the kidney slot that matches with the hangnail of stay 2; Described plug body 1 is provided with and stay 2 shapes, the corresponding rectangular window of size.

In order to reproduce the present invention, by reference to the accompanying drawings assembling and the effect of each parts of the present invention are further specified:

Among Fig. 2, stay 2 is inserted in the groove of Plug base 4, and stay 2 is with Plug base 4 plug body 1 of packing into during assembling, when advancing to plug body 1 inner chamber, stay 2 is extruded Plug base 4, therefore, can put into easily plug body, in 1; Stay 2 tail ends and contact pin contacting piece 3 are fixed in the plug body 1 by 5 embeddings of plug casting glue.

According to Fig. 1, the rectangular window that gets out of the way stay 2 is arranged on the plug body 1, this rectangular window and stay 2 have certain gap, guarantee that deflection and the resilience of stay 2 in rectangular window do not stopped.

Among Fig. 6, jack contact 7 is fixed in the inner chamber of jack housing 6 by 9 embeddings of socket casting glue with socket base 8, be processed with kidney slot on the jack housing 6, this groove cooperates with the hangnail of stay can realize connector locking and release, this groove is kidney-shaped, mainly be beneficial to and mill processing, reduce difficulty of processing.

Among Fig. 7, when plug and socket carry out butt-joint locking, it at first is plug body, 1 inserts jack housing 6 carries out guide-localization, then the hangnail inclined-plane of stay 2 contacts with the fillet surface of jack housing 6, stay 2 is extruded inward collapsible, plug continues to plug together forward, when the hangnail partial row of stay 2 enters the kidney slot of jack housing 6, stay 2 is used lower self elastic force, return to not extruded free state, the hangnail of stay 2 just is stuck in the kidney slot of jack housing 6, thereby realizes the locking that plugs together of connector.When connector needs release to separate, by hand the part of stay 2 hangnails in the kidney slot is inwardly pushed away, the hangnail of stay 2 leaves the kidney slot of jack housing 6, and can pull the plug out of the socket this moment, thereby realize that release separates.
