Description

Bayonet connector

[technical field]

The utility model relates to a kind of bayonet connector.

[background technology]

At present, industry is in order to be connected to memory module the bayonet connector on the circuit board, as Chinese CN01143101.6 patent, generally include the insulation frame that is installed on the motherboard, be used to keep the latch member of daughter board on the frame with being connected in second angle, daughter board at first is inserted into first angle and forwards second angle in the frame then to, and wherein said latch member comprises: the lock bolt body of metal, and it has the frame coupling part of the frame of being connected to and the daughter board retained part of clamping daughter board; With the metal reinforcement member of separating to the lock bolt body of motherboard with soft soldering; Described fixed part is installed on the tab portion that is bent to form from the lock bolt body, and can move in the preset range in vertical direction.But this kind bayonet connector, its latch member complex structural designs takies more space, is not easy to dismounting, is unfavorable for increasing work efficiency.

Therefore, be necessary to design a kind of novel bayonet connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of novel bayonet connector, and it is simple in structure, and easy disassembly can effectively be increased work efficiency.

In order to reach above-mentioned creation purpose, the utility model bayonet connector, it comprises: insulating body, offer central slot along its longitudinally, a pair of fixed structure, it is located at the two terminal relatively of insulating body, described fixed structure comprises the metalwork and the fixture that can cooperatively interact, described insulating body is provided with and can limits the groove that fixed structure moves at longitudinally, described fixed structure is provided with and can limits the position limiting structure that metalwork moves at horizontal direction, and can guarantee the location structure that metalwork moves in the vertical direction preset range.

Compared with prior art, the utility model bayonet connector, it is simple in structure, and easy disassembly can effectively be increased work efficiency.

Fig. 4 is the sectional perspective exploded view of another embodiment of the utility model bayonet connector.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model bayonet connector is described further.

Please be simultaneously referring to figs. 1 through shown in Figure 3, the utility model bayonet connector is used to accept butt joint electronic component (not icon) and comprises the insulating body 1 that is longitudinal, offers central slot 10 along its longitudinally; Plurality of conductive terminals 2 is located at the both sides of central slot 10, with machinery and electric connection memory module, and 1 liang of terminal relatively stepped groove 11 that is provided with of described insulating body; A pair of fixed structure 5, it is located at 1 liang of terminal relatively groove 11 of insulating body, described groove 11 can limit metalwork 3 moving at longitudinally, described fixed structure 5 comprises the metalwork 3 and the fixture 4 that can cooperatively interact, described fixed structure 5 is provided with and can limits the position limiting structure that metalwork 3 moves at horizontal direction, and can guarantee the location structure that metalwork 3 moves in the vertical direction preset range.Wherein each metalwork 3 comprises that one is fixed in the main part 30 of insulating body 1, can be soldered to the fixed part 31 of circuit board (not icon), and be positioned at the auxiliary section 34 of described metalwork 3 ends, this auxiliary section 34 is contained in the groove 11 loosely, described fixed part 31 is outwards bent to extend to bend downwards to extend again by main part 30 and is bent to form, be provided with at least one pad 310 (being provided with four pads on the described in the present embodiment fixed part) on the described fixed part 31, described pad 310 is the projection on the fixed part 31, through being stamped to form, can play the effect of firm welding, described main part 30 is arranged in groove 11, is used for metalwork 3 is fixed on insulating body 1; Each fixture 4 can match with metalwork 3, and in order to fixing butt joint electronic component, this fixture 4 comprises body 40 and the pulling part 41 that is extended by body 40 bendings, and can hold the clamping part 42 of butt joint electronic component.Wherein, described pulling part 41 can be beneficial to and pull fixture 4 horizontal by certain angle, and described pulling part 41 is provided with chamfering, can not cause adversary's injury.

Described metalwork 3 also comprises the described protuberance 32 that is extended to form by main part 30 bendings, correspondingly, on fixture 4, also be provided with the protuberance 43 that matches with protuberance 32, described protuberance 32 is formed above-mentioned position limiting structure with protuberance 43, and described location structure comprises and is arranged on both sides on the metalwork 3 towards the width of the distance between 33, two location divisions 33, location division that fixture 4 extends greater than metalwork 3 correspondence positions.Described location division 33 can make fixture 4 move in the horizontal direction, the phenomenon that can occur being offset not, in addition, when described fixture 4 when being subjected to the external force of vertical direction, because the restriction of described location division 33, thereby can guarantee the phenomenon that described fixture 4 can not occur teetertottering.Described metalwork 3 can insert in the described groove 11 together with after fixture 4 matches.Wherein, described fixture 4 is fixed in the groove 11 of insulating body 1, and described metalwork 3 can move freely within the specific limits, is beneficial to so that fixed part 31 develops naturally on circuit board and carries out surface adhering.Wherein, described fixture 4 is positioned at the outside of groove 11, and described metalwork 3 is positioned at the inboard of groove 11, such setting, when the impact that is subjected to external force, its active force major part all concentrates on the fixture 4, can make metalwork 3 not be subjected to the influence of external force, thereby phenomenon loosening or that come off can not appear in the fixed part 31 that can guarantee metalwork 3.

Please refer to shown in Figure 4ly, be second embodiment of the utility model bayonet connector, itself and the first embodiment difference are: described fixed part 31 is bent inwards by main part 30 and extends to form, and same, it also can reach identical effect.
