Abstract

The utility model relates to a blind plug of a communication device, which comprises a contact head (1), a jack (2), a bushing (3), an inner conductor (4), an insulator (5), a shell, a spring (9), an inner tooth washer (10) and a washer (11). The shell comprises a first shell (6), a second shell (7) and a third shell (8); the jack (2) is pressed into the insulator (5); the insulator (5) and the jack (2) are pressed in the first shell (6); the third shell (8) is arranged in the first shell (6); the washer (11) is arranged in the third shell (8); the spring (9) is sleeved on the first shell (6); the second shell (7) penetrates through the spring (9) and then is pressed in the first shell (6); the inner tooth washer (10) is arranged in the second shell (7); the contact head (1) is pressed in the second shell (7) to the step thereof; and the bushing (3) is pressed in the second shell (7) to the step thereof. The utility model can prevent the vibration, and serve as a cushion during the blind insertion process.

Description

A kind of blind plug for communication instrument

Technical field

The utility model relates to a kind of communication products accessory, is a kind of a kind of blind plug that is used on the communication instrument, specifically a kind of communication instrument connector.

Background technology

The wiring board of communication instrument generally all can be adorned a lot of plugs, blind slotting form is all adopted in being connected between wiring board and the wiring board, if the structure of plug is all-in-one-piece will confronting the tough with toughnees, make wiring board and wiring board be difficult to couple together, and the butt joint installation accuracy is very high, can be easy to damaged line plate and joint.

The utility model content

1, technical problem to be solved:

The purpose of this utility model is to connect inconveniently at existing communication instrument circuit plate, causes damaging in the plug process of being everlasting the problem of connector and wiring board, a kind of split type, the connector that inside adds spring buffer that design.

2, technical scheme

The utility model comprises contact head 1, jack 2, lining 3, inner wire 4, insulator 5, shell, it is characterized in that: also comprise spring 9, internal tooth packing ring 10, packing ring 11, described shell comprises first shell 6, second shell 7, the 3rd shell 8, jack 2 is pressed in the insulator 5, insulator 5 and jack 2 are pressed in first shell 6, the 3rd shell 8 is put into first shell 6, packing ring 11 is put into the 3rd shell 8, spring 9 is enclosed within on first shell 6, second shell 7 passes spring 9 and is pressed in first shell 6, internal tooth packing ring 10 is put into second shell 7, and contact head 1 is pressed into second shell 7 to step, and lining 3 is pressed into second shell 7 to step.

3, beneficial effect

The utility model increases the tight fit of a spring 9 and a packing ring 11, makes this product can against shock, can be in the blind effect of playing buffering in slotting, and its performance is more stable.

The utility model has changed the structure of former contact head 1, and this product can be out of shape under the situation of continuous operation.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

Fig. 1, wherein 1 is contact head, and 2 is jack, and 3 is lining, and 4 is inner wire, and 5 is insulator, and 6 is first shell, and 7 is second shell, and 8 is the 3rd shell, and 9 is spring, and 10 is the internal tooth packing ring, 11 is packing ring.

A kind of blind plug for communication instrument comprises contact head 1, jack 2, lining 3, inner wire 4, insulator 5, first shell 6, second shell 7, the 3rd shell 8, spring 9, internal tooth packing ring 10, packing ring 11.Jack 2 is pressed in the insulator 5, insulator 5 and jack 2 are pressed in first shell 6, the 3rd shell 8 is put into first shell 6, packing ring 11 is put into the 3rd shell 8, spring 9 is enclosed within on first shell 6, second shell 7 passes spring 9 and is pressed in first shell 6, characteristic by spring makes product can guarantee the product reset condition under the situation of static state, do not influence properties of product, internal tooth packing ring 10 is put into second shell 7, contact head 1 is pressed into second shell 7 to step, and lining 3 is pressed into second shell 7 to step.

The utility model has adopted the operation that increases a spring and a packing ring, and original all-in-one-piece product is made into tight fit by spring and packing ring, makes product not influence properties of product again, and the effect of playing buffering can increase useful life again.As shown in Figure 1.

Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection range of the present utility model should be defined with the application's claim protection range is as the criterion.
