Abstract

The utility model relates to a connecting terminal for an electric connector, comprising a base part. Two elastic arms extend out of one end of the base part to form a clamping opening, and a connecting pin extends out of the other end of the base part; at least one elastic arm on both sides of the clamping opening of the connecting terminal is connected with a bending clamping edge. By the structure, when a formula terminal is inserted into the clamping opening for connecting, a connecting area can be increased by the clamping edge of the elastic arm to ensure the stable effect of electrical connection. In addition, because the clamping edge is integrally formed when the two elastic arms are punch formed, the utility model is easy to manufacture.

Description

The splicing ear of electric connector

The utility model relevant a kind of electric connector, the particularly splicing ear of relevant a kind of electric connector.

See also Fig. 1, it is a kind of D type electric connector of known low order double-row type, it is provided with the preceding sheath body 11 of a metal, one plastic body 12, a plurality of terminals 13 and a plastic rear cover 14, wherein body 12 is provided with a plurality of slots 121, its both sides respectively are provided with positioning piece 15, terminal 13 has length respectively, short terminal, it is the moulding of sheet metal integrated punching, be provided with a base portion 131, base portion one end extends two elastic arms 132 and forms a folder mouth 133, and the other end extends a pin 134, its two elastic arm 132 is inserted the slot 121 of body, and pin 134 stretches out outside the slot, and preceding sheath body 11 is sleeved on body 12 front ends, and bonnet 14 is placed on body 12 rear ends.

Above-mentioned terminal is a matrix, so in the use with the D type electric connector of a formula terminal, shown in Fig. 2,3, when two connectors connect, formula terminal 16 inserts connection from the folder mouth 133 of terminal 13, in use have following shortcoming, that is: because two elastic arms, the 132 Elastic Contact terminals 16 of terminal 13 are section 1321, section is a sheet metal thickness, not only contact area is very little but also burr are arranged, so the stability that is electrically connected is not good, and also can scratch formula terminal, still remain improvement; But the terminal of this kind pattern has an advantage, simple structure, more or less freely and saving material in the manufacturing.

Because the electrical connection poor effect of above-mentioned electric connector, so the matrix terminal further is designed to the coating mode, as announce the terminal that is this pattern for No. 222148, see also Fig. 4, its terminal 17 is provided with a base portion 171, base portion one end is provided with a junction 172, the other end connects a pin 173, connecting portion 172 is around being rolled into the pipe shape, and front end 174 need strike out bell mouth shape, though this terminal has preferable electrical connection effect, yet this terminal not only increases the processing procedure difficulty on making, and also increase greatly of material, cost is increased.

Main purpose of the present utility model is to provide a kind of and has good electrical connection effect, and the splicing ear of the electric connector that can reduce cost.

For achieving the above object, the utility model is taked following measure:

The splicing ear of electric connector of the present utility model comprises a base portion, and base portion one end extends two elastic arms and forms a folder mouth, and the other end extends a pin, it is characterized in that, the Jia Kou both sides of described terminal have at least an elastic arm to be provided with the folder edge of bending.

The splicing ear of electric connector is characterized in that, a described folder mouthful two-side elastic arm is equipped with the folder edge.

When the formula terminal of above-mentioned form inserts folder and mouthful connects, can increase the connection area by the folder edge of elastic arm, can guarantee to be electrically connected effect, and since folder be formed in one during because of punch forming two elastic arms, very easy in manufacturings.

Reach embodiment in conjunction with the accompanying drawings, characteristics of the present utility model be described in detail as follows:

The accompanying drawing simple declaration:

Fig. 1 is the three-dimensional exploded view of known D type electric connector.

Fig. 2 is the schematic side view of known D type electric connector terminal when connecting.

Fig. 3 is the front-view schematic diagram of known D type electric connector terminal when connecting.

Fig. 4 is the schematic perspective view of the terminal of No. 222148 patent of known bulletin.

Fig. 5 is the perspective exploded view of the utility model embodiment.

Fig. 6 is the schematic side view of the utility model embodiment terminal.

Fig. 7 is the front-view schematic diagram of the utility model embodiment terminal.

Fig. 8 is the front-view schematic diagram of the utility model embodiment terminal when connecting.

Fig. 9 is the schematic side view of the utility model second embodiment.

Figure 10 is the plane decomposing schematic representation of the utility model the 3rd embodiment.

Figure 11 is that the terminal of the utility model the 3rd embodiment amplifies schematic side view.

See also Fig. 5, sheath body 2, a body 3, a plurality of terminal 4 and a bonnet 5 before the electric connector of present embodiment is provided with one, wherein:

Body 3 is made of plastics, and is provided with a plurality of slots 31, and both sides respectively are provided with positioning piece 32.

Please cooperate and consult Fig. 6,7, terminal 4 has long and short terminal respectively, it is by the moulding of metallic plate integrated punching, be provided with a base portion 41, base portion 41 1 ends extend two elastic arms 42, form a folder mouth 43, and the other end extends a pin 44, its two elastic arm 42 is put human body's slot 31, and pin 44 1 ends stretch out the folder edge 45 that the elastic arm of slot 41 outer folder mouthful 43 both sides is provided with bending.

Preceding sheath body 2 is made by metal material and is sleeved on body 3 front ends.

Bonnet 5 is made of plastics, and is placed on body 3 rear ends.

See also Fig. 8, when formula terminal 16 inserts folder mouthfuls 43, folder edge 45 formed folder faces 46 by elastic arm 42, not only can increase and connect area but also be not that section does not have burr (section is 47) fully, stablizing effect in the time of can guaranteeing to be electrically connected, moreover, because folder edge 45 is formed in one when punch forming two elastic arms, be very easy in the manufacturing, production cost is also low.

The terminal of the foregoing description adopts surface adhesive type, sees also Fig. 9, and it is expressed as the utility model and adopts the spot welded type terminal, and its pin 44 does not bend.
