Description

Electric connector

The present invention relates to a kind of electric connector, for example resemble the latch or the socket that are used to be connected to power supply.

Generally there are two types as traditional embedded electric connector.One type of shell that comprises that an electric termination integrally forms by the interpolation stitch within it, and another kind of type is a kind of packaging, wherein electric termination is placed between the shell separately.

For the type of above-mentioned interpolation stitch, if produce when opening circuit near the coupling part of electric connector and conductor wire or electric connection terminal, electric connector is irreparable.So, usually can only be with new whole leads and connector be all changed.

Then can repair these parts that open circuit for modular electric connector, thereby must separate and open shell, in order to connect electric termination and lead.In this case, each connects all necessary bonding part that embeds corresponding shell, two ends of termination, and the expensive time is wanted in this work.

The present invention is intended to provide simple structure by the end at shell, overcomes the problems referred to above, simplifies the assembling of electric connector.

For achieving the above object, the invention provides a kind of electric connector, it comprises:

A shell, this shell comprise a main part, and it contains a pair of end holes that is parallel to each other; With a platform level, this level is to form by the end of cutting described shell along the plane of the radial centre lines that contains two end holes, and described level and described main part are globalities;

A cover part utilizes screw on described level contact portion;

The electric termination of a pair of bending, they insert in the described end holes separately;

Each contact surface of described level and described cover part has: first pair of groove, be total to extension point-blank and when described cover part touches described level, lead to described end holes to form bullport, with second pair of groove, angle is arranged extend to described first pair of groove, this angle is corresponding to the angle of bend of the electric termination of above-mentioned electric termination, so that form fixed end-hole when described cover part touches described level, these fixed end-holes lead to described bullport respectively;

Wherein, each described electric termination is inserted in the described separately end holes and is engaged to the bullport that leads to end holes and the fixed end-hole that leads to bullport, and this level contacts with cover part and be fixed with each other.

Wherein, described electric termination is respectively circular axial pin shape termination.

According to said structure, first pair of groove and second pair of groove on the platform level of shell are respectively the part of bullport and the part of fixed end-hole.In assembling during this electric connector, each electric termination is passed on the platform level groove as guide recess, and is inserted into the end holes that is connected with this guide recess, rotates electric termination then vertically, makes it to be meshed with corresponding groove.Therefore, fully prevented the rotation, rising of electric termination and remove from its position.Then, connect with first pair of groove and second pair of groove of platform level respectively by the first pair of groove on the contact-making surface that makes cover part and the second pair of groove, make electric termination be fixed and be engaged in cover part and the platform level between, with screw cover part and platform level are fixed together then.Therefore, can easily assemble electric connector, and not have rotation, rising and the position of electric termination to move.

Fig. 1～Fig. 3 shows one and applies alternating magnetic field to promote sanguimotor magnetic therapy instrument to human body.

This magnetic therapy instrument comprises a plurality of housings, and each housing comprises a magnetic field generator that produces alternating magnetic field, and they are pivotally connected by linkage 12, and tie up tape splicing 13 on the housing 1a of two ends.This therapeutic equipment is installed on each position of human body, will be applied on the human body from the alternating magnetic field of each magnetic field generator.Magnetic field generator in the shell 1 14 interconnects by going between, and for each housing 1a, the side that is attached with 13 provides according to electric connector 2 of the present invention.

Above-mentioned each shell 1 all is made up of a pair of split shell.On the split shell contact-making surface of shell 1a, be formed with the bonding part 15 of a joint electric connector 2.

As shown in Figure 4 to 7, electric connector 2 comprises, a pair of end holes 31,31, they run through abreast, the end parts of separating shell 3 by the warp-wise center along two ends hole 31 forms a nicked level 32, one by the cover 4 of screw in this band otch platform level 32, and a pair of electric termination 5,5.

On shell 3, be formed with one round the opening of end holes 31 and be coupled to the cylindrical portion 33 of corresponding connector 6, on its periphery, be formed with screw thread 34, in order to be connected to the bag type nut 61 that this connector 6 is provided.

On the contact-making surface of band otch platform level 32 and cover 4, be formed with directly the groove 35,41 that is connected in series mutually with corresponding end holes 31,31, and the branch's groove 36,42 that vertically is communicated with corresponding groove 35,41.When cover 4 is fixed on nicked the level 32, form the bullport 37 that leads to end holes 31 by groove opposite 35,41, form branch and the fixed end-hole 38 that is connected with bullport 37 that goes out by relative branch's groove 36,42.

Being electrically connected termination 5 is circular axial pin shape termination, its size is suitable for end holes 31, bullport 37 and fixed end-hole 38, and by bending to certain angle in position, right angle for example, at one end form the end portion 51 that engages with electric connector 6 respectively, form the standing part 52 that engages with fixed end-hole 38 at the other end.The end of standing part 52 is connected with lead-in wire 14 among the shell 1a.And each is electrically connected termination 5 and inserts corresponding end holes 31 by end portion 51 being passed on the band otch platform level 32 corresponding groove 35, and rolls over standing part 52 down and make it to be meshed with corresponding branch's groove 36 and be fixed; Cover is fixed on the band otch platform level 32.At this moment, end portion 51 stretches into respectively within the cylindrical portion 33, corresponding standing part 52 be set in and be fixed in by branch's groove 36,42 and form in the corresponding fixed end-hole 38.

On cover 4 and shell 3, provide be parallel to two ends fixing hole 38 and stretch out and set in the dividing plate between them 39,43, so that two isolation between the electric termination 5,5 are provided.

On the contact-making surface of cover 4 and shell body 3, be formed with a dowel 7 and a Dowel hole 71 that is used to locate cover 4, and be used for the hole that spins in the tram.

In addition, each fixed end-hole might not be defined as the right angle with respect to the angle of bend of corresponding bullport 37, and it can be according to the mounting condition of electric connector 2 and change.

When the above-mentioned electric connector 2 of assembling, each electric termination 5 is passed on the band otch platform level 32 groove 35 as guide recess, and is inserted among the end holes 31 that is connected with this guide recess.Axially rotate electric termination 5 then, so that its standing part 52 is meshed with corresponding branch's groove 36.Therefore groove 35 on the otch platform level 32 inserts electric connection terminal 5 as guiding groove on the connection stomidium 31 that is communicated with, electric connection terminal 5 engages on branch's groove 36 of the fixed part 52 of rotating shaft.Therefore, the rotation of electric termination 5, rising and the situation that moves apart its position are prevented fully.Then, connect with being with groove 35 and branch's groove 36 on the otch platform level 2 respectively, electric termination is fixed and is engaged between cover 4 and the band otch platform level 2 by making groove 41 and branch's groove 42 on the cover 4.By screw cover 4 and band otch platform level are fixed then.

In addition, electric connector 2 of the present invention might not limit and be used for illustrated therapeutic equipments, and it also can be applied on various electronic instruments and the office equipment.
