CN201246026Y - Key with cipher key chip and lock head - Google Patents

Abstract

The utility model relates to a key and a lock head which are provided with an encryption chip. The key and the lock head include a key and a lock head which are provided with an encryption chip. A chip is arranged inside the encryption key, the information pin of the chip integrates data, address and power supply together, the information pin and the grounding pin of the chip are shaped and plastic-sealed in a key casing. In order to ensure the contact transmission with the lock head, the information pin and the grounding pin are exposed outside the key head in sufficient length, and in order to ensure correct insertion and contact, the key head is made into the shape of a water drop with a larger end and a smaller end. The lock head comprises an elastic information sheet, an elastic grounding sheet, an elastic contacting sheet, a lock head casing and a lock head cover. The elastic information sheet, the elastic grounding sheet and the elastic contacting sheet are made of beryllium bronze sheets and plastic-sealed in the lock head casing, the plug hole of the lock head casing is made into the shape of a water drop which is identical with the key head, the elastic grounding sheet, the elastic contacting sheet and the elastic information sheet correspond to the information pin and the grounding pin of the key head, and the elastic grounding sheet and the elastic contacting sheet form a switch. When the key head is inserted, the information pin and the grounding pin extrude the elastic information sheet and the elastic grounding sheet, the elastic grounding sheet is communicated with the elastic contacting sheet after being extruded to form a channel to the signal ground of the encryption chip, and simultaneously the power ground is communicated.

Description

The key and the tapered end of band key chip

Technical field:

The utility model relates to a kind of key and tapered end with the key chip.

Background technology:

Present electronic lock key and tapered end (dop) only play transmission information basically, and complex structure, cost height, life-span lack, and can not control the break-make of power supply simultaneously.

Summary of the invention:

The utility model is a kind of key and the tapered end with the key chip that designs according to above-mentioned deficiency, and the size of key of its storage reaches 2.8 * 10 ¹⁴, it provides key spoon information transmission channels, the break-make of going back the main control system power supply, and it is simple in structure, safe and reliable, not only economize on electricity but also convenient.

The utility model is to realize like this, be provided with chip in the key spoon (Fig. 1), chip has information pin and grounding leg, and information pin collection data, address are powered at one, information and grounding leg shaping with chip, plastic packaging is in the key shell, and for guaranteeing to contact reliably with the transmission of tapered end (Fig. 2), two leading foots have sufficient length to expose outside key bit, for guaranteeing that not wrong plug connects instead, key bit is made the water droplet shape.

Tapered end (as shown in Figure 2) by the letter shell fragment, shell fragment, contact chip, tapered end shell, tapered end cover constitute.The letter shell fragment, shell fragment, contact chip make by beryllium-bronze, plastic packaging is in the tapered end shell, tapered end shell jack is made the water droplet shape identical with key bit, the letter shell fragment, shell fragment, contact chip and key bit information pin, grounding leg corresponding, ground shell fragment, contact chip composition switch, when key bit inserts, information pin extruding letter shell fragment, grounding leg extruding ground shell fragment is connected contact chip after the ground shell fragment is squeezed, form the passage on key chip information and ground, connect power supply ground simultaneously.

Figure grade: 1 chip, 2 key shells, 3 contact chips, 4 tapered end shells, 5 tapered end covers, 6 ground shell fragments, 7 letter shell fragments

The specific embodiment:

The utility model is that key and tapered end two parts by band key chip constitute, and is provided with chip in the key spoon, and key bit is made into the little water droplet shape of the big end of an end, with the information pin of chip (1) and grounding leg shaping plastic packaging in key shell (2).Tapered end is by contact chip (3), tapered end shell (4), tapered end cover (5), ground shell fragment (6), letter shell fragment (7) constitutes, plastic packaging is in tapered end shell (4), tapered end shell (4) jack is made the water droplet shape that matches with key bit, the letter shell fragment, the ground shell fragment, the contact chip material is the beryllium-bronze sheet, the ground shell fragment, contact chip, signal patch and key bit signal pins, grounding leg is corresponding, ground shell fragment 6 is formed switch with contact chip, when key bit inserts, signal pins, grounding leg extruding letter shell fragment, the ground shell fragment, after being squeezed, connects on the ground shell fragment with contact chip, form the passage on key chip signal and ground, connect power supply simultaneously.

Claims (1)

1, a kind of key and tapered end with the key chip, comprise key and tapered end two parts, it is characterized in that key is the key spoon of microarray strip (1), chip (1) plastic packaging of the key spoon of microarray strip is in key shell (2), information pin and grounding leg have sufficient length to expose outside key bit, key bit is made the little water droplet shape of the big end of an end, tapered end is by contact chip (3), tapered end shell (4), tapered end cover (5), tapered end is by letter shell fragment (7), ground shell fragment (6) constitutes, the tapered end jack is made the water droplet shape identical with key, letter shell fragment (7), ground shell fragment (6), contact chip (3) plastic packaging is in tapered end shell (4), position and key information pin, grounding leg is corresponding, can connect contact chip after the ground shell fragment is squeezed and play transmission and on-off action.
