Description

Improved extended line socket fire line terminal

The utility model relates to a kind of fire line terminal of supply socket, particularly a kind of improved extended line fire line terminal.

Existing extended line socket is combined by a male plug (A) and a female plug seat (D), shown in Fig. 1-4, this male plug (A) includes the ground wire terminal that ground wire terminal is set and puts the fire line terminal of groove (B) and fire line terminal and put groove (C) (referring to Fig. 1, Fig. 2), this female plug seat (D) has the ground wire jack (E) of perforation and two firewire jacks (F) (referring to Fig. 3, Fig. 4), and the male plug that supplies male plug (A) to insert is put groove (G), aforementioned each ground wire terminal is put groove (B) and fire line terminal and is put not target ground wire terminal or fire line terminal are set respectively on the groove (C) among the figure, ground wire terminal and fire line terminal are then distinguished the intercalation part that wiring connects the other end, the male plug A that this combination is finished) after elder generation inserts female plug seat (D), be overmolding to reservation shape with PVC again, insert for plug and use.Because existing extended line socket fire line terminal is to be amounted to mutually by conductive metal sheet to form the clamping contact site, its chucking power intensity is to be produced by male plug restrictions (H), chucking power is relatively poor, and because this fire line terminal must be inserted fire line terminal from top to bottom and be put groove (C), and the two clamping contact sites of amounting to formation have the gap, so this male plug (A) must insert in the female plug seat (D), clad material enters in the fire line terminal clamping contact site when being shaped to avoid coating, and cause the out of use facts, also be, its socket closes and has comprised two elements, and increased group and step, this is the greatest drawback that prior art exists, and structure and group and step are simplified and the enhancing chucking power, becomes the difficult problem that this area demands urgently overcoming.

The purpose of this utility model provides a kind of improved extended line fire line terminal, to simplify the structure of fire line terminal, strengthens chucking power, and makes the extended line receptacle combinations convenient.

The purpose of this utility model is realized by following technical scheme: this fire line terminal one end is provided with an open slot, the other end then is provided with a line end pressing portion, to insert socket fire line terminal insertion groove, after being overmolding to predetermined profile again, for inserting the open slot contact, uses by the live wire plug, this fire line terminal is to be stamped to form with the monolithic conductive metal sheet, its open slot head end has big peristome, there is less restriction contact site the centre, two side outer rims have offset, its thickness has the simplification socket for just inserting the socket firewire jack, combined efficiency height and the good effect of terminal chucking power.When this fire line terminal was connected with the insertion section of socket fire line terminal insertion groove, its conductive metal sheet was corresponding with predetermined fire line terminal insertion groove thickness, and contact site do not have the gap, to save cost.

The utility model has the advantages that compared with prior art: the utility model has reduced by an element, can reduce costs such as die sinking, and the step that can remove plate connector again from has designs simplification, combined efficiency height and the bigger effect of terminal chucking power.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is existing extended line male plug top plan view.

Fig. 2 is existing extended line male plug planar elevation view.

Fig. 3 is an existing extended line female plug seat plane rearview.

Number in the figure is described as follows:

(A) male plug (B) ground wire terminal is put groove

(C) fire line terminal is put groove (D) female plug seat

(E) ground wire jack (F) firewire jack

(G) male plug is put groove (H) restrictions

(1) socket

(10) ground wire jack (11) firewire jack

(12) fire line terminal insertion groove

(2) ground wire terminal

(3) (3 ') fire line terminal

(30) open slot (31) line end pressing portion

(32) the big less restriction contact site of peristome (33)

(34) offset (35) insertion section

Referring to shown in Figure 5, the utility model socket (1) mainly includes a ground wire jack (10) and two firewire jacks (11) of perforation, be respectively equipped with ground wire terminal (2) or fire line terminal (3) on ground wire jack (10) and the firewire jack (11), ground wire terminal (2) and fire line terminal (3) be the intercalation part of the wiring connection other end respectively, this socket is overmolding to reservation shape with PVC again, insert use for plug, above-mentioned socket tail end is one-body molded to have and fire line terminal insertion groove (12) (referring to Fig. 6-8) that two firewire jacks (11) are staggered, inserts for the open slot (30) of fire line terminal (3) one ends and uses (referring to Fig. 5 and Fig. 9-11).So compared with prior art, the utility model has reduced by an element, can reduce costs such as die sinking, and the step that can remove plate connector again from has designs simplification, effect that combined efficiency is high.

The utility model fire line terminal (3) one ends are provided with an open slot (30) (referring to Fig. 5), the other end then is provided with a line end pressing portion (31), to insert socket fire line terminal insertion groove (12), after being overmolding to predetermined profile again, for inserting open slot (30) contact, uses by the live wire plug, above-mentioned fire line terminal (3) is to be stamped to form with the monolithic conductive metal sheet, its open slot (30) head end has big peristome (32), there is less restriction contact site (33) centre, the utility model is that the restriction contact site (33) with fire line terminal (3) itself produces preferable chucking power, two side outer rims have offset (34), this offset (34) inserts in the open slot (30) for the live wire plug, the space that designed openings groove (30) expands outwardly, its thickness is for just inserting socket fire line terminal insertion groove (12).Because this thickness and fire line terminal insertion groove (12) are suitable, so when coating shaping, do not have clad material and enter the defective that is caused in the fire line terminal insertion groove (12).In addition, be to save cost, this fire line terminal (3) is in the insertion section (35) of inserting socket fire line terminal insertion groove (12), can be conductive metal sheet and amounts to and become to be scheduled to fire line terminal insertion groove (12) thickness.Be pressed into predetermined thickness with thin conductive metal sheet doubling, escapable cost is referring to another fire line terminal (3 ') among Fig. 5.And amount to contact site and do not have the gap, clad material enters when avoiding coating shaping), have socket, combined efficiency height and the good effect of terminal chucking power of simplification.
