Abstract

The utility model relates to an electric connector which comprises an insulating body and a conductive terminal contained in the insulating body. The bottom wall of the insulating body extends downwards to form a plurality of locating columns, and each locating column comprises a guiding part and a buckling part which are separately arranged. The electric connector can be stably fixed on a printed circuit board through the buckling parts of the locating columns of the bottom wall of the insulating body, thus the condition that the electric connector easily falls off or is easily pulled out from the printed circuit board due to improper use or the action of outside force can be avoided.

Description

Electric connector
[technical field]
The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that is used to connect chip module.
[background technology]
Such as No. the 2741214th, Chinese utility model patent the electric connector of announcement, it is used for chip module is connected to printed circuit board (PCB), and it comprises insulating body, is contained in conducting terminal, the lower house that is used to accommodate insulating body that is used to connect chip module and printed circuit board (PCB) in the insulating body, the action bars that is articulated in the upper shell of lower house one end and is used for fixing lower house.Wherein, extend under described insulating body lower surface one side direction and be formed with smooth cylindric reference column, the extent of the protrusion of this reference column is compared conducting terminal, and to stretch out the length of insulating body long, therefore, when electric connector is mounted on the printed circuit board (PCB), these reference columns can at first enter on the printed circuit board (PCB) and play guide function in the corresponding location hole that is provided with, and can avoid the terminal bending of conducting terminal, guarantee that conducting terminal and printed circuit board (PCB) accurately align.
But, the reference column of the electric connector insulating body lower surface setting of prior art is smooth cylinder, when it cooperates with the corresponding location hole of printed circuit board (PCB), can't offer the good insertion feel of operator, cause the operator to insert excessively easily, and then cause the terminal bending of conducting terminal; On the other hand, because of reference column is smooth cylinder, so electric connector cooperates with the installation of printed circuit board (PCB) and built on the sand, in improper use or have under the situation of external force effect, electric connector comes off on printed circuit board (PCB) easily or extracts, thereby influences the normal use of electric connector.
Therefore, necessary existing electric connector is improved to overcome the shortcoming of prior art.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector, and it can be stablized and is immobilizated on the printed circuit board (PCB).
For reaching above-mentioned purpose, the utility model provides a kind of electric connector, and it comprises the insulating body of the some reference columns of diapire downward projection formation and is contained in the interior conducting terminal of insulating body; Described reference column comprises guidance part and the clamping part that separates setting.
Compared to prior art, electric connector of the present utility model has following beneficial effect: the clamping part that its mat is located at the reference column of insulating body diapire can be immobilizated on the printed circuit board (PCB) electric connector is stable, avoid in improper use or have under the situation of external force effect, electric connector comes off on printed circuit board (PCB) easily or extracts.
[description of drawings]
Fig. 1 is assembled to stereogram on the printed circuit board (PCB) for the utility model electric connector.
Fig. 2 is the stereogram of the utility model electric connector.
Fig. 3 is the stereogram of electric connector other direction shown in Figure 2.
Fig. 4 is the front view of electric connector shown in Figure 1 and printed circuit board (PCB).
[embodiment]
Below, will introduce the embodiment of the electric connector of the utility model in conjunction with Fig. 1 to Fig. 4 in detail.It is installed on the electric connector of the utility model and is used to connect chip module (not icon) on the printed circuit board (PCB) 2, mainly comprises insulating body 1 and is installed on the interior conducting terminal (not label) of insulating body 1.
Insulating body 1 becomes rectangular configuration substantially, it comprises roof 11 and the diapire 12 that is oppositely arranged, be arranged with the resettlement section 10 that is formed for accommodating chip module among the roof 11, these 10 peripheries, resettlement section extend upward and are formed with two oppose side walls 13 that are oppositely arranged, and resettlement section 10 perforations are formed with some correspondences and accommodate the terminal groove of conducting terminal (not label); Wherein aforementioned relative pair of sidewalls 13 respectively correspondence be provided be convenient to pick and place chip module pick and place breach 131.
12 4 edges of the diapire of insulating body 1 are respectively equipped with reference column 14, these reference columns 14 comprise that respectively the guidance part 15 that extends to form from body 1 diapire 12 that insulate reaches and guidance part 15 is oppositely arranged and the clamping part 16 of interval specific distance downwards, in the present embodiment, guidance part 15 is the semi-cylindrical hollow body.These guidance part 15 outsides are provided with along the fin 151 of its projection direction formation, and described clamping part 16 comprises and is positioned at the body 161 of same periphery substantially with guidance part 15 and from the body 161 terminal outwards hook parts 162 of projection formation.Wherein at least one reference column is asymmetric setting with respect to the position of other reference column, placement direction mistake when avoiding electric connector to be mounted on the printed circuit board (PCB) 2.
When electric connector is mounted on the printed circuit board (PCB) 2, the pressing force that the mat operator is downward and reference column 14 is entered in the location hole 21 of printed circuit board (PCB) 2, aforementioned clamping part 16 strain and near guidance part 15 in location hole 21, when the trip 162 of clamping part 16 stretches out outside the location hole 21 of printed circuit board (PCB) 2, the strain of clamping part 16 finishes and makes operator's feedback feeling to a difference insert feels and then prompting operation person's installation.During installation, fin 151 interference engagement of guidance part 15 are in the location hole 21 of printed circuit board (PCB) 2, the hook part 162 of clamping part 16 is snapped in the bottom of printed circuit board (PCB) 2 simultaneously, and electric connector breaks away from printed circuit board (PCB) 2 in the time of can preventing improper use by this or have external force to get involved.
The height of these reference columns 14 stretches out the height of diapire 12 greater than conducting terminal, thereby when electric connector is mounted on the printed circuit board (PCB) 2, these reference columns 14 can be introduced in the location hole 21 of printed circuit board (PCB) 2 correspondences to play guiding and positioning action, avoid the terminal bending of conducting terminal.
