Abstract
The utility model relates to a board end connector capable of being fixed on a PCB in advance. The board end connector comprises a housing and contact terminals fixed on the housing. Position columns are disposed on the housing. The contact terminals and the positioning columns pass through terminal holes and positioning holes which are disposed on the PCB in order to achieve positioning, respectively. The end portions of the contact terminals and the end portions of the position columns are both equipped with buckles. Compared with a product in the prior art, the connector can be firmly fixed on the PCB through the buckle design before soldered so that cases of deviation and loosening are prevented, achieving high yield of the products. The board end connector is suitable for large-scale batch production.
Description
Technical field
The utility model relates to a kind of automotive connector, especially relates to a kind of plate terminal adapter that pre-fixes in PCB.
Background technology
Automotive connector is made up of plastic casing, two kinds of parts of contact terminal.Contact terminal is generally double, and it is three row or four rows that the only a few product is also arranged, and concise and to the point moulding process is the plastic casing injection mo(u)lding, and the terminal punch forming is assembled into connector assembly with fit again.Such automotive connector assembly is commonly called " plug " (Header), and by contact terminal, an end and pcb board are welded to connect, and the corresponding connector of an end and wire harness is realized the connection in automobile loop to inserting.
PCB welding now just develops towards automatic production line direction efficiently, each electronic component is inserted into PCB automatically go up after, send in the automatic spot equipment by streamline.Present ubiquitous problem is: the PCB that inserts good element is in transport process, because influence such as temperature distortion when vibrations that uncontrollable factor produces or welding, the element of pre-determined bit can not produce off normal, loosening, cause welding scrappage height, part need return problems such as weldering easily, influence the large-scale mass production of product.
The utility model content
The purpose of this utility model is exactly to provide a kind of plate terminal adapter that pre-fixes in PCB for the defective that overcomes above-mentioned prior art existence, make that by buckle design connector can be in firm being fixed on the PCB before the welding not, can not produce off normal, situation such as loosening, make and be fit to large-scale mass production by the yield of products height.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of plate terminal adapter that pre-fixes in PCB, this plate terminal adapter comprises housing and is fixed on contact terminal on the housing, described housing is provided with reference column, described contact terminal and reference column pass the terminal hole and the location hole that are located on the PCB respectively and realize the location, and the end of described contact terminal and reference column is equipped with buckle.
Described reference column is square reference column, and the location hole on the PCB is square location hole.
Described plate terminal adapter is provided with two reference columns, and described pcb board is provided with two location holes, and there are following size relationship: t1=t+0.1 in described reference column and location hole; B＞a+0.3; D2=d1+0.5; Wherein, t is the thickness of PCB, and t1 is the distance of reference column buckle original position to location hole opposite side end face, d2 is two distances between the location hole outermost end, d1 is two distances between the reference column outermost end, and a is the width of reference column buckle, and b is the width of location hole.
Compared with prior art, the utility model makes that by buckle design connector can be in firm being fixed on the PCB before the welding not, can effectively avoid connector stitch connector and PCB when not welding to locate, be easy to generate the equivalent risk that rocks, comes off, improve welding quality, make and be fit to large-scale mass production by the yield of products height.

Embodiment
Shown in Fig. 1～3, a kind of plate terminal adapter that pre-fixes in PCB, this plate terminal adapter comprises housing 1 and is fixed on contact terminal 2 on the housing 1, housing 1 is provided with two reference columns 3, contact terminal 2 and reference column 3 pass terminal hole 4 and two location holes 5 of being located on the PCB respectively and realize the location, the end of contact terminal 2 and reference column 3 is equipped with buckle 6, as shown in Figure 4 and Figure 5.In order to improve the firmness of location, the size relationship that reference column 3 and location hole 5 all adopt square structure and reference column 3 and location hole 5 to exist as shown in Figure 6:
t1＝t+0.1；b＞a+0.3；d2＝d1+0.5；
Wherein, t is the thickness of PCB, and t1 is the distance of reference column buckle original position to location hole opposite side end face, d2 is two distances between the location hole outermost end, d1 is two distances between the reference column outermost end, and a is the width of reference column buckle, and b is the width of location hole.
