Abstract

The utility model relates to a novel electric connector with a protective jacket, which mainly consists of a jack, a pin and a bushing. The surface of the jack is provided with an annular groove; the head part of the jack is sleeved into the bushing, and the head part of the bushing is an internal turned edge structure; and the bushing is pressed and connected into the jack groove. When in use, and when the pin is plugged into the jack, the internal turned edge structure on the head part of the bushing can guide the pin, so the pin can successfully enter the jack and can protect the end surface of the jack. At the same time, the size of an inner hole of the bushing is matched with the size of an outer circle of the jack, so that the deformation of a mouth part of the jack after being plugged and unplugged for multiple times can be effectively prevented, the jack can be adequately contacted with the pin, and the electric performance failure can be prevented. The electric connector with the protective jacket has characteristics of simplicity, convenience and quickness in operation, reliability in contact and the like, and is suitable for the connection of circuits among different electronic devices and instruments.

Description

The electric connector that protective sleeve is arranged

Technical field the utility model relates to the device that a kind of circuit connects.

Background technology is along with development of electronic technology, to the tolerance under the convenience of electrical connection, reliability, the adverse circumstances influence etc., proposes increasingly high requirement.So-called reliability comprises two aspects of inherent reliability and dependability, and inherent reliability is meant product determined reliability from be designed into the whole process of manufacturing, and it is the intrinsic attribute of product; Dependability then is meant use, keeps in repair the influence to product.

Contact is the key element of electric connector, and it directly influences the reliability of connector.The electric connector contact that tradition is used generally is made up of jack and contact pin, and during use, contact pin inserts jack, each other transmission signals.Structure like this; Can satisfy instructions for use under normal conditions; If but this connector is under the situation of bearing very big pulling force of cable or often plug; The contact of inserting the back can not contact or contact is virtual connection and touches phenomenon, and electrical property just might lose efficacy, and this inefficacy mainly concentrates on the contact.If this connector is in the comparison rugged environment, perhaps crudy is more coarse, and then jack entering contact pin is not easy to look for to the position, uses comparatively time-consuming, effort.

The purpose of utility model content the utility model is, overcomes the deficiency that the traditional circuit connector exists, and a kind of safe and reliable, electric connector contact conveniently is provided.

The utility model is achieved in that

Mainly form by jack and sleeve pipe.Socket surfaces has an annular groove, and the jack head is inserted in sleeve pipe, and the sleeve pipe head is the in-flanges structure.Sleeve pipe links to each other in the crimping of jack groove location.

During use, when contact pin was inserted jack, sleeve pipe head in-flanges structure played guide effect to contact pin, made contact pin get into jack smoothly and had protected the jack end face.Overlap pipe orifice size and jack excircle dimension simultaneously and coincide, effectively prevent socket oral area distortion after repeatedly plugging, make jack can fully contact, prevent that electrical property lost efficacy with contact pin.

The utility model has characteristics such as simple and efficient to handle, that contact is reliable.Be applicable to that the circuit between various electronic equipments, the instrument connects.

Description of drawings

Fig. 1 contact pin, jack contact structures cut-away view;

Fig. 2 female part master TV structure cut-away view;

Fig. 3. jack structure figure;

Fig. 4. sleeve structure figure;

Among the figure, 1 sleeve pipe, 2 jacks, 3 contact pins, 4 annular grooves, 5 in-flanges structures

Embodiment is below in conjunction with the embodiment of the utility model of accompanying drawing narration

Fig. 1 has shown contact pin, the jack contact structures cut-away view of present embodiment.During use, contact pin 3 inserts jack 2, and peristome in-flanges structure 5---guide pin gets into jack to sleeve pipe 1 fast, and the jack oral area is strutted simultaneously, contacts with the cover pipe orifice, has limited the distortion of jack oral area.

Fig. 2 has shown female part master's TV structure cut-away view of present embodiment.Jack 2 heads are inserted in sleeve pipe 1, and sleeve pipe 1 carries out crimping in jack annular groove 4 positions---and be connected jack 2 with sleeve pipe 1 and be fixed up.

Fig. 3 has shown the jack figure of present embodiment.Jack 2 profiles are for circle and have annular groove 4, and the external diameter of jack is φ 2.The jack end face is 7.9cm to the cannelure distance.

Fig. 4 has shown the sleeve structure figure of present embodiment.Sleeve pipe 1 profile is circular, and peristome has in-flanges structure 5---can play quick guide effect in the use.Casing length 8.6cm, internal diameter are that φ 2 coincide with the jack outside dimension, can effectively prevent the distortion of jack oral area.

Claims (1)
