Abstract

Plug for a connector assembly, consisting of a plug and an accompanying mating plug, the plug having a connector housing (20) on which a locking latch (10) is arranged which, during the mating of the connector assembly, the locking latch comes into contact with a portion of the mating plug, whereby the locking latch is designed as a separate part which can be connected to the housing.

Description

The plug that is used for termination

Technical field

The present invention relates to a kind of plug of termination, be used for matching with the subsidiary supporting plug of termination.

Background technology

Termination is common components in circuit network, for example, and in telecommunication circuit or in the contained circuit of automobile.Plug by termination and subsidiary supporting plug can be connected to cable on another cable or be connected on other parts in the circuit.

In any environment, plug and supporting plug are fixed together to guarantee positive electric connection.Each element fixed or a kind of method of locking is to adopt the locking latch in terminal box.Along with plug and supporting plug fit together, plug is in contact with one another with the groove of the corresponding formation of supporting plug.

The plug of termination and supporting plug are not always to be made by same manufacturer, in their specific embodiment, and seldom can standardization.Therefore termination generally all is developed into and has multiple admissible change (tolerance).Therefore, connecting part be plug and supporting plug cooperate and the process freed in, the danger of existence is: tolerance can change, and the locking device function is incorrect, that is, the locking latch of plug can be cut off.In addition, because the action of pegging graft may be different, and owing to engage with to separate required power obviously different, locking latch Problem of Failure is more serious.

Summary of the invention

The purpose of this invention is to provide a kind of plug that is used for termination, but this plug presents more standardized insert action with respect to the supporting plug made from allowable tolerance.

Above-mentioned purpose realizes that by a kind of like this plug this plug comprises: terminal box; The locking latch, it is installed on the described terminal box, and in plug and supporting plug engagement process, contacts with the part of described supporting plug; It is characterized in that, described locking latch is designed to separating component, also comprise the fastener that is used to be fixed on the box body, so that at plug with before supporting plug matches, this locking latch can be fastened on the outer wall of terminal box, and this locking latch comprises from its outstanding latch projection, is used for forming locking with described supporting plug.

According to the present invention, the plug that is used for termination or connector assembly has the terminal box of fixed latch latch on it, so that in plug and supporting receiving member or plug engagement process, the locking latch contacts with the part of supporting plug.The locking latch is a separated components, can be connected on the terminal box.But locking latch independent design and irrelevant, but therefore can be connected on the supporting plug with multiple allowable tolerance with terminal box.

The locking latch is made by presenting the material that has a higher strength characteristics than joint-box compound, can guarantee like this being connected of plug and supporting plug can repeatedly use (inject or extract) repeatedly, and prevent only use as the traditional plug situation the locking latch that just fractures soon.

Terminal box can be used the synthetic material manufacturing, and this material is made easily and be in light weight.

In another embodiment of plug of the present invention, when being designed to have the hardware of latch projection, realized by the locking latch embodiment of the change of plug, compare this hardware with traditional synthetic material and be not easy wearing and tearing.And because easy punching and deep-draw processes, cost of manufacture is very low.

In one embodiment, the locking latch is arranged on the outer wall of terminal box, and comprises and be used for the locking latch is fixed on fastener on the terminal box wall.

According to another embodiment of this plug, a groove is arranged on the sidewall of terminal box and in the bottom of locking latch and extends, so that supporting plug can be pressed into the locking latch in the described groove with elastic type.In the present embodiment, can reduce plug is latched in required power with supporting plug.

Description of drawings

The embodiment of the invention is described as follows with reference to the accompanying drawings, wherein:

Fig. 1 a and Fig. 1 b are the perspective views of locking latch;

Fig. 2 is the broken away view of the terminal box that is fixed thereon of locking latch;

Fig. 3 is the terminal box perspective view that has lid; And

Fig. 4 a and Fig. 4 b are front view and the cutaway views that has the terminal box part of locking latch;

Embodiment

Fig. 1 illustrates the locking latch of separation, it can be connected to (as shown in Figure 2) on the terminal box, in this embodiment, the locking latch is the hardware 10 that has latch projection 11, this hardware 10 has part or the

arm

12,13 that stretches out in the opposite direction from latch projection 11, be provided with V-type at the free end of

arm

12,13 and widen part, this part has the groove by its extension.

As shown in Figure 2, hardware 10 is fixed on terminal box 20 sidewalls of connector assembly, hardware is extending with the direction that cooperates the axis almost parallel of supporting plug with the longitudinal axis almost parallel of terminal box 20 and with plug, be formed with groove or load mould 21 in the sidewall of terminal box 20, so that hardware 10 is contained in 21 li of grooves.By being positioned at the locking latch in terminal box 20 grooves 21, groove 14,15 cooperates so that hardware 10 is fixed on the terminal box 20 with the

projection

22,23 of stretching out from box side wall.In addition, the locking latch is fixed on the terminal box box body 20 and can realizes by ultrasonic bonding or hot riveting (heat caulking).

Fig. 3 illustrates the perspective view of the terminal box 20 that has lid 30, when they are bonded together, forms the synthetic socket (two-pin synthetic socket) of double-pin of plug, and they are suitable for the plug contacts holding metal spigot or be used for stube cable.

With reference to Fig. 4 b, the cross-sectional view of the hardware 10 on the sidewall that is fixed on box body 20 is shown.Under the latch projection 11 of hardware 10 and outside a little

arched arm

12,13, be furnished with groove 24 on the sidewall of junction box body 20.

In the connector assembly engagement process, projection 11 is under the pressure of the part of the corresponding formation of supporting plug (not shown) on the connector assembly, but 24 li of indentation grooves.Because

projection

11 and 12,13 elastically deformable in groove, thereby reduced supporting plug is moved required power from bumps.Thus, compared with prior art, obviously reduced plug and cooperated required power with supporting plug.

The structure of the above embodiment and feature can mutually combine easily.
