Holding unit

The utility model is about a kind of holding unit, refers in particular to a kind of circuit board firmly to be mounted on holding unit on the electric connector.

The prior art relevant with the utility model can be with reference to United States Patent (USP) the 5th, 584, and 705,5,650,917, Des.418,484,4,349,238 and 5,494, cases such as No. 451.Be illustrated in figure 1 as the constitutional diagram of existing holding unit and electric connector, wherein this holding unit 5 is mounted on the both sides of the insulating body 60 of electric connector 6, comprise that a main part 50 reaches in the holding section 51 that main part 50 1 ends are convexly equipped with, wherein main part 50 is mounted in the bayonet socket 61 of electric connector 6 insulating bodies 60 both sides, and main part 50 tops are located in holding section 51 and extend setting relatively, hold mutually with the bayonet socket 70 with circuit board 7 both sides.But, for guaranteeing main part 50 insulating body 60 suitable smooth installation and the dismountings that pivot and must guarantee circuit board 7 relatively, the main part 50 of holding unit 5 must borrow special mechanism's group on electric connector 6 insulating bodies 60, therefore in the manufacturing of holding unit 5 and insulating body 60 and installation process, need to consider correct cooperation therebetween and need the higher accuracy of manufacture, and this shows to be unfavorable for reducing and produces and assembly cost.Moreover, the bayonet socket 70 that circuit board 7 must be borrowed both sides fastens with the holding section 51 of holding unit 5 and can be immobilizated on the electric connector 6, therefore in the design of circuit board 7 and holding unit 5 and make the laying that also must consider the relative position of the two, this is unfavorable for the convenience that designs and make.

The utility model purpose is to provide a kind of and circuit board firmly can be mounted on the electric connector and simple in structure and be easy to the holding unit making and assemble.

The purpose of this utility model is achieved through the following technical solutions: this holding unit comprises cramping body and the holding body that fastens with cramping body, wherein cramping body comprises two clamping limbs that relatively are provided with and connects the linking arm of this two clamping limb, and also be provided with the accepting groove that is used to accommodate circuit board on the cramping body, be provided with bayonet unit in the clamping limb end again, and holding body is located at the electric connector both sides, comprise draw-in groove of accommodating the clamping limb end and the clamping close device that fastens with the clamping limb bayonet unit, after circuit board is inserted on the electric connector, cramping body is mounted on the board edge periphery, wherein the part lateral margin of circuit board is contained in the accepting groove of cramping body, and the bayonet unit of clamping limb matches with the holding body clamping close device, circuit board then firmly is mounted on electric connector and is effectively prevented to take place between circuit board and electric connector relative rocking thus, to guarantee the reliable transmission of signal between circuit board and the electric connector.

Compared to prior art, after the utility model holding unit and electric connector and circuit board combination, the bayonet unit of the cramping body of holding unit and the clamping close device of holding body fasten, circuit board is contained in the accepting groove, and before the upper limb of circuit board reaches, the cell wall of rear surface and accepting groove offsets, like this, the moving of circuit board all directions can effectively be prevented and can firmly be mounted on the electric connector, moreover, the utility model holding unit is only borrowed the cramping body bayonet unit to engage with the holding body clamping close device and is mounted on the electric connector, its installation and dismounting are quite convenient and be beneficial to and boost productivity and reduce production costs, in addition, in making the utility model holding unit process, production mould be there is no special requirement and is beneficial to the reduction die cost.

Below in conjunction with diagram and embodiment the utility model is further described.
