Abstract

The utility model relates to the technical field of electronic connector elements, in particular to a bonding wire type male for connectors, which comprises a front plastic main body with a metal terminal installed inside and a rear plug arranged at the rear end of the front plastic main body. A metal casing is arranged outside the front plastic main body, and the metal casing extends to the external surface of the rear plug. A snapping protrusion is formed at the external surface of the rear plug, and correspondingly a snapping groove is formed on the metal casing. Based on the previous connecting structure of the front plastic main body and the rear plug of the connector male, the structure of the bonding wire type male for connectors enable the metal casing outside the front plastic main body to extend to the external surface of the rear plug and form a snapping structure of the snapping protrusion and the snapping groove between the external surface of the rear plug and the metal casing. Accordingly, locating of the metal casing and the rear plug is more correct and the connection is closer. Dropping of the rear plug and clearance behind bonding wires are avoided, and normal following process is guaranteed.

Description

A kind of wire welding type male of connector

Technical field:

The utility model relates to electric power connector Element Technology field, refers in particular to a kind of wire welding type male of connector.

Background technology:

Existing wire welding type male with all kinds of connectors of preceding main body of plastic cement and back plug structure, before the plastic cement main body be being connected between fill in the back to realize by the buckle structure of the two both sides moulding, and back plug contacts hardly with metal shell on the preceding main body of plastic cement, also do not have any syndeton.This just makes that the back plug is insecure with being connected of the preceding main body of plastic cement, easily comes off, and Width on a large scale in be difficult to the location, be easy to generate in conjunction with not tight, form problems such as slit behind the bonding wire, in the process of follow-up moulding inner membrance, plastic rubber material overflows into from the slit, thereby causes the generation of defective products.

The utility model content:

The purpose of this utility model is to overcome the above-mentioned weak point of existing this type of connection, and a kind of connection wire welding type male of connector closely is provided.

The utility model realizes that the technical scheme that its purpose adopts is: a kind of wire welding type male of connector, it comprises the back plug that inside is equipped with the preceding plastic cement main body of metal terminal and is installed in described preceding plastic cement body rear, plastic cement main body outside also is provided with metal shell before described, described metal shell extends to the outer surface of described back plug, and the outer surface in described back plug is formed with the buckle salient point, accordingly, on described metal shell, be formed with the buckle groove.

After the utility model adopts said structure, the preceding plastic cement main body of connector male head is filled on the basis of original syndeton with the back, the metal shell of preceding plastic cement main body periphery extends to the outer surface of back plug, and between the outer surface of back plug and metal shell, form the buckle structure of buckle salient point and buckle groove, the plastic cement main body is more accurate with plug location, back before making, connects closelyr, can guarantee that not only the back plug does not come off, guarantee simultaneously not produce the slit behind the bonding wire, guarantee normally carrying out of following process.

Description of drawings:

Fig. 1 is the decomposition texture schematic diagram of the utility model connector male head;

Fig. 2 is the combining structure schematic diagram of the utility model connector male head.

Embodiment:

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

As Fig. 1, shown in 2, the wire welding type male of connector described in the utility model comprises that inside is equipped with the preceding plastic cement main body 1 and the back plug 2 that is installed in described preceding plastic cement main body 1 rear end of metal terminal, plastic cement main body 1 outside also is provided with metal shell 3 before described, metal shell 3 is split type in the present embodiment, a metal shell is installed in the front of plastic cement main body 1 promptly, reverse side is also installed a metal shell, the metal shell 3 on described two sides all extends preceding plastic cement main body 1, can touch with the outer surface of described back plug 2, and the outer surface in described back plug 2 is formed with buckle salient point 21, positive, reverse side all is provided with, accordingly, on described two sides metal shell 3, be formed with buckle groove 31 respectively, therefore, when back plug 2 was connected with preceding plastic cement main body 1, it was connected the buckle groove 31 further reinforcements on the buckle salient point 21 that can utilize back plug 2 and the metal shell 3, makes its connection tightr.Certainly, the buckle salient point 21 of back plug 2 and buckle groove 31 shapes and the quantity on the metal shell 3 can design as required.

The utility model is simple in structure, good connecting effect.

Claims

1. the wire welding type male of a connector, it comprises the back plug (2) that inside is equipped with the preceding plastic cement main body (1) of metal terminal and is installed in described preceding plastic cement main body (1) rear end, plastic cement main body (1) outside also is provided with metal shell (3) before described, it is characterized in that: described metal shell (3) extends to the outer surface of described back plug (2), and the outer surface in described back plug (2) is formed with buckle salient point (21), accordingly, on described metal shell (3), be formed with buckle groove (31).
